Received: 6 September, 2007 Key words: Edemotofibrosc/erotic ponniculitis; Dermoe/ectroporotion; Summary One of the ways of treating EPF (edematofibrosclerotic pa nnic ulitis) is to carry out cycles of intradermal mesotherapy involving the injection of simple drug cocktails with lipolytic and vaso-protective action. The authors decided to verify the possibility of administering the same drugs transcutaneously by means of de1m oelectroporation. This method consists of the application to the skin of special-designed drug-delivery units that emit contro lled , low-intensity electrical impulses, thus causing the ope ning of partic ul ar intercellular cutaneous channels (hydroelectric pores) through which the acti ve molecules are transmitted. The following repo1t provides the history of 23 cases chosen for EPF treatment of the lower limbs (trochanteric areas) with weekly application of a lipo lytic and vasoprotecti ve drug cockta il. The final results confirm the effectiveness of dermoelectroporation fo r the transcutaneous administration of drugs used for the locai reduction of EPF and of localized adiposity.

This technique derives MATERIALS ANO METHODS from the well-known electroporation technique developed by American dermatologists in 1970 . 23 fornaie patients aged between 26 and 52 years Since then , it has been sign ificantly improved (average age: 35) affected by second- and thirda nd , recently, biotechnologically refi ned , to the 3 Transdermal treatment of EPF by means of dermoelectroporation degree EPF were selected. The exclusion criteria adopted were cigarette consumption (more than 10), cu rre nt locai or systemic pharmacological treatment and/or suc h treatment carried out with in three months of the recruitment and other aesthetic treatments under way. The patients were examined in upright posture to assess the presence of skin roughness, chromatic alte rations (dyschro mia, hyperpigmentation) of the skin , skin pallor, teleang iectasia a nd/or micro-varicosity or the presence of stretch marks. After palpation , in order to assess hypothermal variations in the areas concerned and the presence of fine granule micro-nodules at the lower levels, a thermographic exami nation was made of a li the patients in order to determine the extent and seriousness of damage to cutaneous and hypodermal microcircul ation and to determine precisely the extent of the EPF. Ali of the patients were fo und to be within second- and third-degree clinica! and instrumental parameters. Digitai photographs were taken in metrically graduated upri ght posture, anterior, posterior and faterai, pre- and post-treatment. The areas treated were the trochanteric areas. The circumferences of these areas were measured in graduated centimetres in upright posture. The patients were subjected to UT on the left side, wi th 4 -mm , 30-G needles, and to dermoelectroporation on the left s ide. The drug cocktail, used on both sides, consisted of: - in 11 patients: I ml aminophy lline + 2 ml Lymdiaral + 2 ml Venon - in 12 patients: l ml aminophyll ine + I ml Lcarnitine + 2 ml Yenon. For the dermoelectroporation method, the drug cocktai l, in 5-ml syringes, was released into the trochanteric cutaneous area by means of a variable-speed dispenser (0.5 ml/min.). The patients were prohibited from havi ng massages and/or lymph draining during the 72 hours fo llowing the treatme nt. They were also supplied 4 with a clinica! diary in which they were asked to make note of any side effects or complications a nd to make a final assessment of the results. RESULTS The results were collated three months after the beginning of the treatment and were examined using subjective, objecti ve and instrumental criteria. From a subjective point of view, the patients did not referto any complication or side effect from the treatment. They were provided wi th a quartile assessment scale (0 = no resul t, l from O to 25% improvement, 2 from 25 to 50% improveme nt, 3 from 50 to 75% improvement, and 4 from 75 to I 00% improvement) to be completed independently by both the patients and the study personnel at the end of the treatment. O vera li , the results were satisfying: 13 4 th leve!, 7 3rd leve! and 3 2nd leve) as far as the patients were concerned and slightl y more criticai as far as the study personnel were concerned (I 1 4th leve!, 9 3rd leve! and 3 2nd leve!) . From a n instrumental point of view, the final thermographic exam was repeated and showed a reduction in extent and seriousness of damage to the cutaneous and hypode rmal microcircu la tion wi th a reduction of skin rough ness and granularity on both visual inspection and palpation. Comparative examination of the digitai photographs showed reduction of skin blemishes, w ith improveme nt in the profile of the trochanteric fine.

Twe nty six female volunteers in good health used the developed cosmetic products for 28 days. Sensory (clinica! evaluation and selfeva luation) and instrumental (hydration, sebum and pH) measure me nts were performed at the begi nning and after 14 and 28 days of application of the treatme nt. Sensory and instrumental methods indicateci that the objectives of the cosmetic treatment were achieved. After 14 days a significant increase in hyd ration, lightness, smoothness and generai state was ac hi eved, suggesting an improvement in the state of the epidermis . After 28 days, treatment also caused a n increase in wrinkles and elasticity quality scores in old women , whi ch suggests an improveme nt in the state of the dermis. Both clinica! evaluation and selfeva luation methods prov ided similar and comple me ntary information and were able to detect changes in the state of the skin of the volunteers with treatme nt. lnstrumental measurements showed that, despite being ac id and formulateci with iiandu o il , the evaluated cosmetic products did not caused an excessive increase in pH and sebum of the skin of the vo lunteers . Riassunto Scopo del presente lavoro è di valutare l'efficacia di un trattamento cosmetico basato sull ' uso di una crema da giorno ed una crema da notte contenente olio di nandù. A tale scopo sono stati utilizzati metodi sensoriali e strumentali su un gruppo di 26 donne sane volontarie per un periodo di 28 g iorni. ll Evoluotion of the Efficocy of o Cosmetic Treotment Contoining Nondu oil Le val utazioni sensoriali (valutazione chimica e autovalutazione) e strumentali (controllo idratazione, sebo e pH) sono state effettuate dopo 14 e 28 giorni dall' applicazione bi/giornaliera dei prodotti . Con entrambi i metodi si è potuto verificare il raggiungimento dell'obiettivo prefissato. Dopo 14 giorni è stato verificato un incremento dell'idratazione cutanea, della luminosità e levigatezza generale della cute trattata. Dopo 28 giorni è stato anche verificato un incremento della elasticità cutanea accompagnato da un miglioramento delle rughe, dovuto, probabilmente, ad un riassestamento generale del derma. Questi dati sono stati confermati sia dai metodi strumentali che dall'autovalutazione de i soggetti. D'altra parte l'utilizzo dell'olio di fiandù non provoca incrementi nei lipidi di superficie, né del pH cutaneo. 12 M. E. Parente, G. Ares, A. G6mbaro INTRODUCTION Fats and oils, both from ani mai a nd vegetai orig in , have been included in cosmetic products fo r a very long time. Howe ver, de mand for these products has augmented in the last decade due to the increasing interest in incorporating natu ral ingredients in cosmetic products ( I ) . Ratites are flightless birds which include ostrich (Struthio camelus), emu (Dromaeus novaehollandiae), fia ndu comun (Rhea americana) and cho iq ue (Pterocnemia pennata). O ils fro m these birds are commonl y incorporateci in products for both therapeutic and cosmetic use (2,3). T hese o ils a re rich in triacilglicerides with unsaturated fa tty acids as palmitoleic, oleic, linoleic and lino le nic ac id (4), which make their inclusion in cosmetics an interesting possibility. These produc ts might act as lipophilic e mo llients in cosme tic e mulsions. J\Tandu o il contains 62.5% unsaturated fa tty ac ids, which includes 37 .0 % monounsaturated fatty o ils (mainly o leic acid - 34.7%-) and 24.7% polyunsatu rated fa tty acids (5). Besides, fia ndu oil contains high concentrations of linoleic acid (22.2%) and linolenic acid (2.5 %), both essential fatty acids (5) . Essential fa tty ac ids deficit has been reported to cause an abnormal increase in transepide rmal water loss, leading to the developme nt of dry and scaly skin (6). Moreover, lino leic acid or emollie nts containing it have been reported to increase barrie r functi on of the skin , favoring water retention of the stratum corne um (1 ,7) . Therefore , fiandu oil appears as an inte resting acti ve emollie nt. The sensory c haracteristics of fiandu o il were studied in previous work (8). When applied on the skin, this product showed similar sensory characteristics to those of dimethicone. In this work , fiandu oil was classified as a protective fa tty e mo llient due to the fac t that it left an oily film on the skin that lasted severa) times (8). However, the efficacy of cosmetic treatments containing fiandu oil has not been studied . The efficacy of cosmetic products could be regarded as the achieveme nt of the main goals proposed during their developme nt. Efficacy is an important factor for the sales pote ntial of any cosmetic product. If the clinica! acti vity of a certain cosmetic product can be supported by sensoria! perception, this product is more li kely to be successful in the market piace (9). The sta te of the skin during the study of the efficacy of cosmetic treatments could be evaluated using both instrumental and sensory methods. Sensory methods include cl inica! evaluation and selfevaluation. Clinica! evaluation is a sensory method for skin state evaluation pe rformed by expe rts (Dermatologists or Cosmetologists), who objectivel y evaluate the state of a patient's skin by using their senses and adequate methodologies (10). In thi s case, experts evaluate the efficacy of cosmetic products and decide whic h product they consider as better. On the othe r ha nd, selfevaluation consists in a subjective method to evaluate the state of the ski n performed by cosmetic users ( 11 - 19). Severa! authors have used clinica) evaluation and instrume ntal methods to evaluate the efficacy of cosmetic products (1 2, 13, 20 , 2 1), or selfevaluation and instrumental methods (l l - 15, 16, 19). In previous work (22) sensory me thods fo r skin diagnosis were developed , apply ing clini ca) e val uation and selfe valuation, a nd concluded that they provided complimentary information. Wh ile clinica! evaluation provided information regarding the objective state of the skin , selfevaluation provided a measure of the perception that each volunteer has of her skin. The aim of the present work was to use sensory and instrumental methods to study the efficacy of a cosmetic treatment composed of a day cream and a night cream contain containing fiandu oil . 13 Evaluation of the Efficacy of a Cosmetic Treatment Containing Nandu oil MATERIALS ANO METHODS methylparaben (and) propylparaben, a-hydroxiacids -AHA- (Pyrus malus (and) Vitis vinifera (and) Citrus limonum (and) propilenglySubjects col (and) water (and) imidazolidinylurea (and) methyl paraben), fiandu oil, Tocopheril acetate Twenty six female volunteers in good health , of and Xantan Gum.

Gambaro prevention effects due to the presence of antioxidants. Efficacy evaluafion Evaluation of the state of the facial skin of the volunteers was carried out using clinica! evaluation and selfevaluation, as developed in previous work (22). Instrumental measurements (hydration , pH and sebum) were also performed. Three evaluation instances were considered: before they start the treatment, after fourteen days of treatment and after 28 days. Evaluations were carried out under controlled temperature and humidity (20°C and 60% relative humidity) . Volunteers were asked to stay under those conditions for 15 minutes before the evaluation (33, 34). Clinica/ evaluafion A Cosmetologist observed the facial skin of the volunteers and scored different attributes using a structured 9-point quality scale (Table I). The evaluated attributes were: wrinkles (amount and depth), hydration, smoothness, elasticity, lightness and generai state. After the evaluation, the Cosmetologist defined the type of skin of each volunteer (dry, normai, mixed, and greasy) and an interview about skin care and hygiene was performed. Selfevaluafion Volunteers were asked to evaluate the state of their facial skin by scoring the same attributes than the Cosmetologist, using the same quality scale. lnsfrumenfal measuremenfs Three instrumental measurements were performed on the facial skin of the vol unteers: hydration, pH and sebum. Hydration was measured by electrical capacitance using a Corneometer CM825® (Courage + Khazaka electronic GmbH, Koln, Germany). The skin of the volunteers was classified as very dry when the reading was lower than 50, dry when the reading was between 50 and 60, and sufficiently moistured when the reading was higher than 60 (34).

Sebum was only determined before the start the treatment and at the end. When sebum reading was lower than 70 skins were classified as dry, whe n it was between 70 and 180 as normai , and as greasy if sebum reading was higher than I 80. pH was measured using a piane electrode Skin pH meter PH 900®(Courage + Khazaka electronic GmbH , Koln , Germany) . Skin was classified according to its pH in acid skin (pH between 3.5 and 4.4), normai skin (pH between 4.5 a nd 5.5) and basic skin (pH between 5.6 and 6.5). For each volunteer 5 measure ments of hydratio n a nd pH were performed on each cheek, whereas 3 measurements of sebum were performed. Data analysis Analysis of variance (ANOVA) was performed on the instrumental and sensory data obtained considering volunteer and time as variation factors . When differences were significant (p<0.05) means and Fisher's Jeast significant differences were calcul ated. Principal component analysis (PCA) was performed on the clinica! evaluation and selfevaluation data, to illustrate the relationship between variables, and between variables and volunteers. At each evaluation time , volun teers were sorted in groups according to instrumental data fo r hydration, pH and sebum. The ex istence of differences in the volunteers frequency distributions with time was evaluated us ing xl statisti ca! test. An a nalysis of variance (ANOYA) was performed on clinica! evaluation, selfevaluation and instrumental measurements data , considering group as variation factor. When the effects were significant, mean ratings fo r each sample and Fisher 's least significant differences were calc ulated. Diffe re nces were considered significant when p < 0.05. 16 Ali statistica) analyses were perfo rmed using Genstat Discovery Edition (VSN International , UK). RESULTS ANO DISCUSSION Clinica/ evaluation Analysis of variance pe rformed on clinica) evaluation data showed that ali the evaluated attributes varied with time of a pplication of the evaluated cosmetic treatme nt (p<O .00 I) . As shown in Table II, after 14 days of treatment, a significant (p<0.00 I ) improvement was fou nd in softness , lightness, hydration and generai state. This improvement continued until the e nd of the study. Scores increased from 3-4 (defective to enough) to 6 (satisfactory) after 28 days, whi ch shows the efficacy of the developed cosmetic treatme nt. Softness, lig htness and hydration correspond to skin characte ristics that depend on the state of the superficial layers of the skin and therefo re easily a nd quick!y respond to treatment. Considering that the main objective of the proposed treatme nt was to improve these skin attributes, results suggest that it was achieved. On the other hand , wrinkles and elasticity were not significantly affected afte r 28 days of treatme nt. These attributes depend of the state of the dermis and need long treatments (of more than 28 days) to achieve sig nificant improveme nts . Results according to age group As previously mentioned , volunteers were sorted into two groups considering thei r age in young and old women. C li nica) evaluation data was analyzed separately for each of these age groups. As shown in Table ill, similar results were found for young and old women. A sign ificant improve in smoothness, lightness, hydration and gene rai state was registered after 14 days of treatment M. E. Parente, G. Ares, A. G6mbaro for both age groups . Therefore, these results suggest that the efficacy of the developed cosrnetic treatrnent on the epiderrnis did not depend on the age of the volunteers . Thus, it could be used by both age groups for irnproving this aspect of the state of the skin. On the other hand, an increase in elasticity was observed for both age groups after 28 days of treatrnent. Moreover, an irnprovernent in wri nkles was achieved after 28 days only for old wornen. The fact that young wornen did not show an irnprovernent in wrinkles quality scores could be attributed to the fact that they show hi gh scores at the beginning of treatrnent.

This improvement in smoothness , lig htness and hydratio n a fter 14 days o f treatment might e ncourage volunteers to continue the treatment for a longer pe riod , making the treatment poss ible to improve wrinkles and e lasticity, characteri stics that are mo re diffic ult a nd take mo re time to improve.

T hese results suggest that vo lunteers in both age groups perceived the efficacy of the developed cosmetic treatme nt. Differences in the effect of cosmetic treatme nt in wri nkles were observed between young and old wo men . Whi le young women no ticed an improveme nt in wrinkles after 28 days, old wome n d id not notice an improvement in this attribute w ith treatment. However, c lin ica] evaluatio n data showed an improve ment in wrin kles for both age g roups after 28 days of treatme nt. Thus, the se results suggest a difference in the perceptio n of the efficacy of the cosmetic treatment be tween o ld women and the Cosmetologist.

These results are in agreement with previous work (22) and with results fo r clinica( evaluation data. A similar trend was observed when evaluating the relative position of the volunteers before and after 28 days of treatment in the PCA of selfevaluation data than that of clinica) evaluation data. As shown in Figure 4 , 73 % of the volunteers were initially located to the left of PC I , showing low values for smoothness, lightness, hydration , genera! state. Nonetheless, this percentage was inverse at the end of the treatment (after 28 days) as 73% of the volunteers were located to the right of PCl, suggesting a good leve! of care of their skin. Moreover, ali the volunteers moved to the right of PC 1, showing an improvement in their perception of the state of their skin after applying the treatment for 28 days. Some volunteers also moved up in PC2, showing an improvement in wrinkles and elasticity, suggesting an improvement in the state of their dermis. Nevertheless, these displacements were fewe r than those on PC J and were shown by a smaller amount of volunteers, in agreement with clinica! evaluation data. Therefore, these results show that vol unteers perceived the efficacy of the evaluated cosmetic treatment. INSTRUMENTAL MEASUREMENTS Hydration As shown in Table VI, ANO VA showed a highly significant increase in hydration with ti me of application of treatment, which could be attributed to the presence of emollients (fiandu oil and isopropyl miri state) and moisturizing agents (glicerine and urea) in the cosmetic products included in the treatment. These results are in agreeme nt with the increase in hydration scores during clinica) evaluation and selfeval uation. 21 Evaluation of the Effìcacv of a Cosmetic Treatment Containing Nandu oil Wrinkles 0 ,5 ~ .,.; ~ o N (.)

As shown in Table VI, young women showed higher hydration values than old women throughout treatment, as expected due to aging effects on skin . Both age groups showed a significant increase in hydratio n due to treatment. Volunteers were sorted in three categories according to hydration measurements: very dry, dry and sufficientl y moistured.

As shown in Table VII , treatment caused a mar- M. E. Parente, G. Ares. A. G6mbaro ked increase in the percentage of women with hydrated skin and a concomitant decrease of those with very dry and dry skin. Wh ile only 27% of the those showed sufficiently moistured skins at the beginning of the treatment, this percentage increase to 77% after 28 days of treatment. These results show an increase in ski n hydration with treatment, suggesting the efficacy of the evaluated treatment. Sebum end of the treatment. ANOVA showed that volunteers showed higher sebum scores (p<O .05) at the end of the treatment, wh ich could be attributed to the presence of emollients and waxy substances (gliceryyl stearate and cetearyl alcohol) in the cosmetic products included in the treatment. As shown in Table VIII, old women showed lower sebum scores than young women throughout treatment. This differe nce could be explained considering a decrease in the secretion of the sebaceous g landules with aging .

Table IX presents type of skin freque ncy distribution of the volunteers, according to their sebum scores, at the beginn ing and the end of treatment. As shown in Table IX, a slight decrease in percentage of volunteers with dry skin and a paralle l increase in women with normai skin were o bserved after 28 days of treatment. O n the other hand , as the evaluated cosmetic p roducts contained na nd u oil an excessive increase in sebum could be expected. However, it is important to indicate that after 28 days of treatme nt no increase was registered in percentage of women with greasy skin. These res ults suggest that the increase in sebum due to treatment was restricted to women with very low levels of sebum. caused a significa nt decrease in pH after 28 d ays, for both young and old women. This could be attributed to the low pH of the cosmetic products that composed the treatment. The skin of the volunteers was sorted in three categories according to pH measure ments: acid, normai and basic. Table XI shows type of skin freque ncy distribution, considering pH, th roughout treatment. As shown in Tab le XI, no significant di ffere nces we re found with time application of treatment in the type of skin distribution of volunteers. Thus, although the evaluated night c ream was ac id (pH=4) it only caused an slight acid ification of the skin of the volunteers. CONCLUSIONS Both sensory and instrumental methods provided useful information to evaluate the efficacy of the developed cosmetic treatme nt. Both clinica! evaluatio n and selfevaluation methods provided similar a nd complementary information and were able to detect cha nges in the state of the skin of the volunteers with treatme nt. pH As shown in Table X, the e valuated treatme nt TABLE VIII Average scoresfor sebum scores of the volunteers througlww treatme111, for the wlwle popu/ation and by age group.

On the other hand, selfevaluation could be regarded as a measure of how satisfied consumers are with the evaluated cosmetic treatment and with its effects on their skin. Sensory and instrumental methods indicateci that the objectives of the cosmetic treatment were achieved. After 14 days a significant increase in hydration, lightness, smoothness and generai state was registered , suggesting an improvement in the state of the epidermis. After 28 days, treatment also caused an increase in wrinkles and elasticity scores in old women, which suggests an improvement in the state of the derm is. Instrumental measurements showed that, despite being acid and formulateci with fiandu oi l, the evaluated cosmetic products did not caused an excessive increase in pH and sebum of the skin of the volunteers.

" Fractional Photothermolys is" seeks to onl y damage certai n zones within the selected target area, (producing tiny dot, or pi xel-like treated areas on the skin) , leaving the othe r zones within it perfec tly intact; hence only causing fractional damage through the heat of the light source. T his allows the skin to heal much fas ter than if the whole area was treated , as the ' healthy' untreated tissue surrounding the treated zones helps to fili in the damaged area with new cells . T he Authors examine the effects of this new procedure on the skin , w ith the aim of analyze the treatment, exploring the c utaneous reaction to various laser pulse durations a nd energies by means of the macroscopic reaction and histo logical appraisal. Riassunto Il res urfacing fraz ionale è una nuova tecno logia che colma una nicchia unica nei protocoll i di ring iovanimento c uta neo . "La Fototermolisi fraz ionale" riesce a danneggiare solo parzialmente il tessuto bersaglio, producendo piccole colonne di coagulazione, lasc iando le altre zone tra di esse pe rfettamente intatte. Provoca, quindi, esclusivamente un danno frazionale grazie al calore della luce laser, e le zone risparmjate dal trauma fungono da serbato i di rigenerazione per la produzione delle nuove cellule . Gli A utori esaminano gli effetti di q uesta nuova procedu ra sulla pelle, con lo scopo d i a nalizzare il tratta mento attraverso le reazioni cutanee da un punto di vista macroscopico ed isto logico a d iverse durate dell'impulso e a diverse energie. 29 The Effects on the Skin of a New Fractional Laser.

Jr is possible to identify a reticulum of "microscabs" simi/ar to the theoretical print of the fractional lens array of the laser. 32 From the comparison between the first series and the second one, probably the alterations of the keratinocytes and the dermis after the laser irradiation , is a "vita!" phenomenon that has developed within the 24 hours of observation and is consequent to a thermal insult concentrated inside the microspots and caused by the laser beam. P.Mezzana, G. Coppola In ali the cases, damage to leve! of the corne um layer does not exist and it is interesting to notice the presence of free melan in in the epidermis . Lowe r times of exposure and fl uence (es . 5ms, 5mJ/MTS) determi ne damage to the leve! of the basai membrane and an overheating of the superficial dermis without coagulation. The basai membrane carries out a fundamental ro le of support and regulation of the cellular prolife ration (sees improvement of the texture), it is a structural support and al lows fo r the nourishment and the refuse to diffuse . It acts as a fi lter for macromolecules, a nd also a zone of polarization of the cells, in the regeneration process as it works a "freeway" fo r the cellular migrati on. Its alteration therefore, that happens also at re latively low parameters, can already justify the positive observations on the improvement of the c utaneous texture at low laser parameters . The max imum depth of coagulation in the test is 600 m icron using 11 mJ/MTS (fig. 5). The syste m can reach 20 mJ/MTS and the coagulation columns can reach in the dermis at approximately 900 micron. 33 The Effects on the Skin of a New Fractiona/ Laser.

The Conference was accompanied by " tabletop" exhibition, in wh ich cosmetic universities and academies, branch publishers and cosmetic industry representatives participated. This year Conference was held under the banner "Education and science for beauty" . Four sessions devoted to cosmetic active ingredients , technologies used in formulation of new products, permeation abil ity of cosmetic ingredients through the skin and hair as well as a perfumery session took piace during two days of the conference. Altogether, 28 speeches were given. For the first time, the separate commerciai sessions and technical workshops for the clients of raw material s suppliers were organized. The conference was also accompanied by poster session , in wh ich about thirty posters displaying scientific research with in cosmetic chemistry and cosmetology were presented. The leve! of speeches was very high. Polish cosmetology was represented mainly by young people originating from various academic circles and presenting the results of research carried out within the range of master and PhD studies. Apart from specialists from Poland, a number of foreign guests gave lectures: Elio Mignini - President of SICC (Societa Italiana di Chimica e Scienza Cosmetologiche), Torsten Clarius (Cognis) , Michael Schuricht (Symrise), Horst Westenfelder (DSM Nutritional Products). The Conference gathered about 350 participants. AFC Conference was the opportunity to meet scientists, lecturers , specialists and professionals from Poland and European countries, among whose there were representatives of ali most important uni versities educating in cosmetology, cosmetic chemistry and related sciences, as well as numerous group of students.

Thus epithe li al defense aga inst infection agents relies on the recognition of microbial products by patte rn recognition receptors and the locai production of a ntimicrobial peptides . These toll-like receptors are early sensors of microbial materiai in both , epithelial cells and dendritic cells, and thus init iate immune responses way before the specific or immune system is alerted .

This was the topic of Prof. Hong -Duo Chen, Prof Xing-Hua Gao,and Yu-Xiao Hung from the famous and oldest China Medicai University in Shenyang.

Meanwhile textile industry is booming, derrnatologists have established a bridging role in testing and evaluating ali the effects of fibe rs on the skin, at both lab and clinic settings. And innovati ve textiles may be produced by the use of the Italian patented chitin nanofibrils with new properties and significant advantages, for exarnple, in wound care. This natural and safe polyglucoside rnay be constructed with cornbination of other fibers of different densities to enhance and optimize the direct transport of fluids into the textile (Fig.4), but it may be used also to produce quality and natural textiles exhibiting antibacterial activities with a special wear comfo1t cornpared to synthetic one. But according with rny opening topic this nanostructured chitin rnay have an interesting use as cosmetic and/or drug carrier and as a natural skin moisturi zing ingredie nt or as biodegradable polymer for the engineering and rege neration of different tissues (Fig.5). ?«,J_,... , "'"lii'.'.!~~ •• • ••0 • o0 o0oo~g0000000 °oo0 o oo~g~JJ0o0o o 00~0000000 00~000000 Fig. 4 Textile produced from chitin ' nanofibrils.

China has, in fact, the biggest production volume of texti le and the awareness of unwanted effects clothing may have on human health has increased also. Therefore, according with these scientists, Chinese dermatologists are paying 40 Nanotechnology will therefore be ab le to spearhead innovation , giving new impetus to a globalized and even faster trade. But the ability to market nano-structured products will depend on the ability of companies to produce and contro! this new class of products, meeting the needs of both man and the environrnent, on the Special Reports abi lity of govemment to regulate their production and use quickly and effecti vely, and on the abi lity of the products themselves to meet the needs and expectations of consumers. Biofunctional textiles but innovative cosmeceuticals and nutraceuticals also, were among the more than 200 topics presented , October 20-23 , of last year, in a wonderful Beijing. Fig. s Activity of chtin'nanofibrils on wound healing. But what about Traditional Chinese Medicine (TMC)? According with Professor X iran Lin (Fig.6) Dept. Dermatol of Dalian Medicai University, cosmeceuticals have already emergent in China from at least 1700 years. In Zhou Hou Fang, a classica! medicai book of ancient China, written by Ge Hong, formulae composed of traditional Chinese drugs , were used to improve people's appearance. Since then, a number of trad itional Chinese herbs, as Fructus Trichosanthis, Radix Angel icae Sinesis, Radix Ginseng, etc. have been recorded in medicai literatures in the past dynasties to compose form ulae used for cosmetic purpose. These herbal medicines , according to the theoretical system of TCM, are deemed to possess the actions of invigorating Qi and nourishing blood, removing blood stasis, eliminating heat and promoting the blood circulation , removing dampness and relieving itching. These actions will balance the Yin and Yang (Fig.7), coordinate the Qi and blood, promote the physio logical fu nction and consequently bring about a holistic cosmetic effect. This is why the trad itional Chinese doctor refer to phys iognomy, wh ich is the art of discovering temperament and character from outward appearance. For this diagnos is he often uses the E ight Character system to make a comprehensive analysis of the patient's inborn and postnatal constitution as well as lifespan. ---- .jl;I; ..&\. ~ ......., Fig. 7 A painting representation ofYin and Yang.

The system is used in fortu ne telling and is based on I Ching, or The Book of Changes, a Taoism classic. In the ancient time, in fact, TCM and Taoism were inseparably bound up in each other. Many Taoists were doctors, and nearly ali doctors were Taoists. 41 Special Reports And ali of us obtained a royal welcome.
