Adipose tissue stromal vascular fraction in the treatment of full thickness burns in rats

Acta cir. bras; 31 (9), 2016
ABSTRACT PURPOSE: To analyze the healing effects of stromal vascular fraction (SVF) application compared to wound dressing with 2% silver sulfadiazine in full thickness burn wounds in rats. METHODS: Animals were divided into two groups: 2% silver sulfadiazine group and SVF group. Both groups received o...

Antioxidant effects of açaí seed ( Euterpe oleracea ) in anorexia-cachexia syndrome induced by Walker-256 tumor

Acta cir. bras; 31 (9), 2016
ABSTRACT PURPOSE: To assess antioxidant effects of açaí seed extract on anorexia-cachexia induced by Walker-256 tumor. METHODS: A population of 20 lab rats were distributed into four groups (n=5): Control Group (CG), which only received tumor inoculation. Experimental Group-100 (EG-100), with anima...

Efecto de la adrenomedulina cerebelosa frente al estrés agudo

Invest. clín; 57 (3), 2016
La adrenomedulina (AM) es un péptido involucrado en la regulación cardiovascular. En el cerebelo, la densidad de los receptores de la AM se encuentra alterada durante la hipertensión, sugiriendo un posible papel del sistema adrenomedulinérgico cerebelar en la regulación de la presión arterial (PA)....

Caracterização de um modelo de paralisia cerebral em ratos: cognição e estrutura do hipocampo e amígdala

Rev. bras. neurol; 52 (3), 2016
FUNDAMENTO: A paralisia cerebral (PC) é caracterizada por distúrbios do movimento e da postura, que podem estar associados a déficits cognitivos. Tais comprometimentos são atribuídos a lesões não progressivas ao encéfalo em desenvolvimento. No âmbito experimental, modelos animais dessa condiçã...
