Benzodiazepines are one of the most frequently prescribed drugs due to their anxiolytic properties. The aim of this study was to evaluate the effects of diazepam on lipopolysaccharide-induced peritoneal acute inflammatory responses. Swiss mice were treated with diazepam in a single dose of 1 or 10 mg/kg- subcutaneously 1 h before an intraperitoneal injection of lipopolysaccharide or sterile saline solution. The mice were killed 16 h after and the cells were washed from the peritoneal cavity to determine the total number of cells and the mononuclear and polimorfonuclear subpopulations, as well as the TNF-alpha activity and percentage of spread macrophages. Our results showed that the diazepam treatment (1 and 10 mg/kg) induced a significant reduction in the LPS-induced macrophage stimulation and TNF-α activity. Diazepam (10 mg/kg) also reduced the inflammatory cellular migration when compared to the control. It can be concluded that the diazepam treatment in a single dose is able to influence the inflammatory cellular influx, macrophage stimulation and TNF-α activity in the acute inflammatory response in mice, having possible implications on the anti-infectious response efficiency.

This study aimed to evaluate the use of sweet potato as a substrate for the production of spirits. In order to promote an alternative technologically feasible, an experimental design was performed to minimize the operations of preparation, defining the most adequate conditions for the fermentation process. From sweet potato flour obtained by milling and dehydration process of the roots was carried out an enzymatic process of hydrolysis-saccharification of suspension of sweet potato flour with 18% dry matter. The hydrolyzate was used in the fermentation process which followed the 23 full factorial experimental design with central and axial points, and the independent variables were the concentration of reducing sugars, concentration of viable yeast and fermentation temperature. The dependent variables were viable cells, residual sugar, ethanol, glycerol and methanol. The dependent variables were quantified by liquid chromatography. The data analysis indicate that the best fermentation conditions among the tested conditions were: concentration of yeast 5 x 107-1 x 108 in number of viable cells, total reducing sugars from 12.5 to 13.5% and temperature between 33 -34ºC.
