ABSTRACT
The purpose of this study was to investigate the anti-hyperlipidemic effect of soy bean extract solution fermented by Bacillus subtilis MORI (BTD-1E) in obese db/db mice. Eight-week-old male db/db mice were administered 33.3 mg/kg BTD-1E solution orally once a day for four weeks. The BTD-1E group showed significantly lower body weight compared with the db control group (P<0.05). The BTD-1E group showed significantly lower serum total cholesterol and LDL cholesterol levels compared with the db control group, respectively (P<0.05, P<0.01). The BTD-1E group showed significantly decreased liver weight relative to final body weight compared with the db control group (P<0.01). After four weeks of BTD-1E administration, lipid droplets in the liver were apparently decreased in the BTD-1E group compared to the db control group. In summary, our results suggest that BTD-1E has an anti-hyperlipidemic effect in the obese mouse model.

Peel off facial masks, based on polyvinyl alcohol (PVA), are formulations that, after application and drying, form an occlusive film over the face. After removing, they provide cleanness, tensor and moisturizing effects, removing dead cells, residues and other materials deposited on the stratum corneous. The soybean extract fermented by Bifidobacterium animalis has sugars, amino acids, peptides, proteins and free isoflavonoids in high concentrations, when compared to the unfermented extract, providing benefits to the cosmetic formulations like anti-aging effect, moisture, tensor action and emollience. The cosmetic bases of peel off facial masks, added with 5.0 percent w/w of fermented soybean extract, were submitted to Preliminary and Accelerated Stability Studies. Eight (8) preparations were evaluated in several conditions of temperature (-10.0, 5.0, 22.0 and 45.0 ºC) and time (maximum of 15 days), comparing the results with the initial condition (48 h after preparation). The variables observed were: organoleptic characteristics, pH and appearing viscosity value and film drying time. The preparation containing 17.0 percent w/w of PVA and 0.5 percent w/w of guar gum was selected between the eight preparations initially prepared, because it presented the best performance in the stability test, being recommended storage at low temperatures (5.0 ºC).
As máscaras faciais peel off a base de álcool polivinílico (PVA) são formulações que, após a aplicação e secagem, formam um filme oclusivo sobre a face e, após sua remoção, conferem limpeza, ação tensora e hidratação à pele, retirando células mortas do estrato córneo, resíduos e outros materiais depositados. O extrato de soja fermentado por Bifidobacterium animalis possui açúcares, aminoácidos, peptídeos, e alto teor de isoflavonas na forma livre, quando comparado ao leite não fermentado, propiciando benefícios às formulações cosméticas, como ação antienvelhecimento, hidratação, efeito tensor e emoliência. As bases cosméticas de máscaras faciais peel off, acrescidas de extrato de soja fermentado 5,0 por cento p/p, foram submetidas aos ensaios de Estabilidade Preliminar e Acelerada, avaliando-se 8 preparações em diversas condições de temperatura (-10,0; 5,0; 22,0 e 45,0 ºC) e tempo (máximo de 15 dias), em relação à condição inicial (48 h após o preparo). As variáveis observadas envolveram: características organolépticas, valor de pH, viscosidade aparente e tempo de secagem do filme. A preparação contendo 17,0 por cento p/p de PVA e 0,5 por cento p/p de goma guar foi a selecionada dentre as oito preparações elaboradas inicialmente, por ter apresentado melhor desempenho no teste de estabilidade, sendo recomendado o armazenamento em temperatura reduzida (5,0 ºC).
