In order to investigate modulating effect of total tomato saponin(TTS) on uric acid, we used hypoxanthine, oxonic acid potassium salt, and uric acid and potassium oxyzincate to establish hyperuric acid model mice, and investigated the effects of TTS on uric acid excretion, blood uric acid, urea nitrogen, creatinine, xanthine oxidase and organ index in normal mice and hyperuricemic mice. The experimental results were as follows: TTS did not affect the blood uric acid level in normal mice, and the blood uric acid values in the normal group and the low, medium and high dose groups of TTS were(170.4±36.7),(178.3±69.7),(175.5±42.1),(185.3±72.6) μmol·L-1, respectively. TTS could reduce blood uric acid level and xanthine oxidase activity in hypoxanthine and oxonic acid potassium salt combination-induced hyperuricemia mice, and the blood uric acid values in normal group, model group and TTS high dose group were(140.4±36.7),(378.3±69.7),(278.3±62.6) μmol·L-1, respectively. The xanthine oxidase values in the normal, model and TTS low, medium and high dose groups were(1.2±0.3),(1.8±0.2),(1.6±0.2),(1.5±0.3),(1.3±0.4) U·g-1 liver, respectively. TTS reduced blood uric acid levels and decreased xanthine oxidase activity in mice with hyperuricemia induced by the combination of uric acid and oxonic acid potassium salt, and the blood uric acid values in normal group, model group and TTS high dose group were(98.8±21.8),(455.6±78.8),(333.7±68.7) μmol·L-1, respectively. The xanthine oxidase values in the normal, model and TTS high dose groups were(2.1±0.3),(2.5±0.2),(2.3±0.2) U·g-1 liver, respectively. The above results suggest that TTS does not affect blood uric acid levels in normal mice, but can reduce blood uric acid levels in mice in a hyperuricemia acid model, and the mechanism may be related to the reduction of xanthine oxidase activity.

The slope instability and destruction of the banks of rivers and lakes often cause serious casualties and huge economic losses,and there are many factors that lead to the instability and destruction of slope. In this paper,four kinds of laboratory model tests for the instability and collapse failure of the homogeneous Xiashu clay slope with different sand rates were carried out,the erosion process of the slope on the instability and collapse failure under the influence of water level fluctuations and underwater scours were analyzed,and the underwater disintegration tests for the samples of Xiashu clay with different sand rates were carried out. The results show that the composition of soil mass has important influence to the stability of slope. Under the joint action of water level fluctuations and underwater scours,the Xiashu clay slope without sand is the most stable,the higher the sand content of homogenous slope,the weaker the ability of the slope to resist underwater scours and water level fluctuations,and the shorter the time of the slope’s unstable slide collapse. The influence of water level fluctuations and underwater scours to the stability of the slope varies greatly with the difference of sand content of the slope soil. With the increase of the sand content of the slope soil,the influence of underwater scours to the collapse of the slope is getting smaller and smaller,and the effect of the water level fluctuations on the slope unstable collapse is more and more important. The disintegration of soil samples with different sand contents in water is very different. The samples with low sand content of Xiashu clay disintegrate slowly in water. With the increase of sand content in soil,the disintegration rate of samples becomes faster and faster [ABSTRACT FROM AUTHOR]

In this paper, firstly, the methyl eleostearate (ME) was prepared via transesterification of tung with methanol, then epoxidized methyl eleostearat (EME) was synthesized via the reaction of methyl eleostearate with hydrogen peroxide and acetic acid under the catalysis of concentrated phosphoric acid. Finally, the tung oil based polyol (TO-based polyol) was acquired through the reaction of EME with diethanolamine (DEA) using cationic photoinitiators (triarylsulfonium salts) as catalytst via ultraviolet photocatalysis. The products were confirmed by the characterization results of fourier transform infrared spectroscopy (FT-IR), ultraviolet-visible spectroscopy (UV-vis), nuclear magnetic resonance spectroscopy (NMR) and gel Permeation Chromatography (GPC). The results showed that TAS could catalyze the ring-opening reaction of EME with DEA under UV irradiation, and the hydroxyl value of TO-based polyol was 599.54 mgKOH/g and the average relative molecular mass was 544.

To study the effects of L-arabinose on modulating levels of uric acid in hyperuricemia and normal mice. L-arabinose were administrated to hyperuricemia mice and normal mice. Mice models with hyperuricemia were induced with oxonic acid potassium salt and hypoxanthine or with oxonic acid potassium salt and uric. We determinated levels of urate excreted. We also measured levels of uric acid, total cholesterol, triglyceride, glucose, creatinine, urea nitrogen in serum, xanthine oxidase activity in liver and small intestine, liver index, kindey index and spleen index. The results showed that L-arabinose could promote uric acid excretion, but had no effect on serum levels of uric acid in normal mice; could promote serum levels of uric acid, but had no effect on uric acid excretion in mice models with hyperuricemia induced with oxonic acid potassium salt and hypoxanthine; had no effect on uric acid excretion and serum levels of uric acid in mice models with hyperuricemia induced with oxonic acid potassium salt and hypoxanthine uric. This indicates that L-arabinose has no effect on normal serum levels of uric acid; but can promote serum levels of uric acid in mice models with hyperuricemia induced with oxonic acid potassium salt and hypoxanthine.

KM Alzheimier's disease mice models caused by D-galactose,the abilities of learning and memory of mice were investigated by avoid dark experiment in all animals,and antioxidant were used to study protective effects of fordia cauliflora hemsl on the D-galactose induced senile dementia model mice. Fordia cauliflora hemsl could increased antioxidant and decreased lipids,but the results suggested that fordia cauliflora hemsl and fordia cauliflora hemsl butanol extract might be beneficial to inproving the learning and memory behaviors in mice with Alzhemiers' disease induced by D-galactose. The results of pharmacological experiment results confirmed that the active part of fordia cauliflora hemsl butanol extract. [ABSTRACT FROM AUTHOR]
