PLLA/Triethyl citrate membrane as an alternative for the treatment of skin wounds

Bioresorbable polymers can be applied as membranes to sustain and guide cell growth through the regeneration process. This study evaluated poly(acid lactide), PLLA, membranes with addition of 10% triethyl citrate as skin wound healing in Wistar rats. Initially a 2cm² skin wound was exercised of the back of 24 animals. The animals were divided into two groups: treated, whose the polymer membrane was implanted, and control, in which the wound was kept exposed. The results obtained after 1, 3, 7 and 15 days showed an inflammatory response more satisfactory in the implanted wounds, with early repair and collagen more organized when compared to exposed wounds. In addition to, the protected areas showed no irritant inflammatory response which could be attributed to the membrane. Thus, we conclude that the PLLA/Triethyl citrate membrane has effectively protected the wounds, allowing the repair and presenting itself as a promising skin dressing.Polímeros sintéticos biorreabsorvíveis podem ser utilizados sob a forma de membranas para sustentar e guiar o crescimento celular, através do processo de reparação tecidual. Este trabalho avaliou membranas de poli(ácido lático), PLLA, com adição de 10% de trietil-citrato usadas como curativos de feridas cutâneas agudas em ratos Wistar. Inicialmente uma ferida de 2cm² foi provocada na região dorsal de 24 animais. Estes foram divididos em 2 grupos: tratamento, nos quais as feridas foram recobertas pela membrana polimérica e controle, com feridas permanecendo cruentas. Os resultados obtidos em 1, 3, 7 e 15 dias mostraram uma resposta inflamatória mais satisfatória nas feridas protegidas pelas membranas, com reparação precoce e colágeno mais organizado quando comparadas com as áreas incialmente mantidas sem proteção. Além do que, as áreas protegidas pelas membranas não mostraram alterações inflamatórias irritativas que pudessem ser imputadas ao uso da membrana polimérica. Diante disso, conclui-se que a membrana de PLLA/Trietil-citrato protegeu efetivamente as feridas, permitindo o processo de reparação e mostrando-se promissora como curativo cutâneo.798806Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Contribution to the floristic knowledge of the head of the Po Valley (Piedmont, north Italy)

In 2014, the annual field trip of the working group for Floristics, Systematics, and Evolution of the Italian Botanical Society was held in Piemonte (northern Italy), at the head of the Po Valley. This valley, at whose extremity is located the Monviso (3,841 m a.s.l.), belongs to the Cottian Alps about which very little is known from a floristic point of view. An inventory of the taxa of vascular plants collected during the field trip is reported here. The research led to the identification of 3,546 exsiccata, kept in nine public and nine private collections. A total of 669 taxa belonging to 79 plant families were recorded. Six taxa resulted endemic to Italy and three exclusive to Piemonte, while only nine alien species were detected; six taxa are new and five confirmed for the regional flora

Foliar epicuticular wax of Arrabidaea brachypoda: flavonoids and antifungal activity

Abstract The epicuticular wax of the leaves of Arrabidaea brachypoda was analyzed for its flavonoid content and four compounds (1-4) were isolated. They are known flavonoids and showed antifungal activity against Cladosporium sphaerospermum. They were identified by mass spectrometry, proton nuclear magnetic resonance spectroscopy and nuclear Overhauser effect spectroscopy (NOESY) as 3Ј,4Ј-dihydroxy-5,6,7-trimethoxyflavone (1), cirsiliol (2), cirsimaritin (3) and hispidulin (4). Two major chemical features resulting from this work are the first report of 1 as a natural product and the first finding of cirsiliol in Bignoniaceae. 2002 Elsevier Science Ltd. All rights reserved.
