Abstract
Mollusc shells are composed of more than 95% calcium carbonate and less than 5% of an organic matrix consisting mostly of proteins, glycoproteins and polysaccharides. Previous studies have elucidated the biological activities of the shell matrices from bivalve molluscs on skin, especially on the expression of the extracellular matrix components of fibroblasts. In this work, we have investigated the potential biological activities of shell matrix components extracted from the shell of the scallop Pecten maximus on human fibroblasts in primary culture. Firstly, we demonstrated that shell matrix components had different effects on general cellular activities. Secondly, we have shown that the shell matrix components stimulate the synthesis of type I and III collagens, as well as that of sulphated GAGs. The increased expression of type I collagen is likely mediated by the recruitment of transactivating factors (Sp1, Sp3 and human c-Krox) in the −112/−61 bp COL1A1 promoter region. Finally, contrarily to what was obtained in previous works, we demonstrated that the scallop shell extracts have only a small effect on cell migration during in vitro wound tests and have no effect on cell proliferation. Thus, our research emphasizes the potential use of shell matrix of Pecten maximus for dermo-cosmetic applications.

Abstract
A somatotropina, além do efeito anabolizante, age no processo de cicatrização acelerando a formação local de tecido de granulação, síntese e deposição de colágeno, quando administrada por via subcutânea. Objetivo: Avaliar o efeito da somatotropina sobre a cicatrização de feridas cutâneas, em ratos. Métodos: Utilizaram-se 53 ratos Wistar, machos, com idade média de 145,19 dias e peso inicial médio de 287,72 g, divididos em dois grupos: controle (n=26) que recebeu 1,2 ml/dia de água destilada pela via subcutânea e experimento (n=27) que recebeu 0,2 UI/kg/dia de somatotropina humana pela mesma via. Fez-se uma ferida cutânea no dorso do animal, que diariamente era medida, procedendo-se ao final do experimento o cálculo de contração da ferida. Os tempos de aferição foram 3, 7 e 14 dias, quando de 9 animais de cada grupo, coletou-se sangue para dosagem bioquímica de proteínas plasmáticas e ressecou-se a ferida para estudo histológico. À microscopia avaliou-se: epitelização, reação inflamatória local, tecido de granulação, neovascularização e fibrose. Resultados: O cálculo de contração da ferida, nos 3 tempos de aferição, não demonstrou diferenças entre os grupos controle e experimento. Na dosagem bioquímica encontrou-se diminuição das proteínas totais (p=0,007) e aumento da relação albumina/globulina (p=0,03) no 14º dia no grupo controle, enquanto o grupo experimento manteve-as constantes. Na avaliação histológica observou-se significante aumento da fibrose no 7º dia no grupo experimento (p<0,0001). Conclusões: A somatotropina mantém constantes a relação albumina/globulina e as proteínas totais plasmáticas no 14º dia, além de intensificar a fibrose cicatricial quando utilizada durante 7 dias.

Abstract
The components of the cutaneous envelope, the epidermis and the dermis, change in response to aging or environmental stress factors. The fibroblasts involved in maintaining skin tone are the main targets. Nacre, mother of pearl, from Pinctada maxima, which can stimulate and regulate bone forming cells, was implanted in the dermis of rats to test its action on the skin fibroblasts. This report describes the effect of nacre on the skin fibroblast recruitment and physiological activity. It resulted in enhanced extracellular matrix synthesis and the production of components implicated in cell to cell adhesion and communication (such as decorine) and in tissue regeneration (type I and type III collagens). The nacre implant produced a well vascularized tissue. The physiological conditions in the region around the implant are thus those required for the positive interactions between the dermis and epidermis which are fundamental for the physiological function of the skin.
