RESUMO
Objective: To observe the effect of herba artemisiae capillaris extracts (HACE) on the expression profile of microRNA (miRNAs) in the kidney tissue of the diabetic rats, and to explore the protective effect of HACE on the kidney tissue of diabetic rats from the miRNA angle. Methods: A total of 60 male Wistar rats were divided into control group (n=12), model group (n=24) and HACE group (n=24). The urinary albumin excretion rate and urinary protein excretion rate of the rats in various groups were detected. HE staining was used to detect the morphology of the kidney tissue of the rats in various groups after treated for 8 and 16 weeks; miRNAs chips were used to screen the expressions of miRNAs in the kidney tissue of the rats. The positive miRNAs were screened out from those with differentially expression amounts higher than 1. 74 times as well as high abundance, and RT-qPCR was used to verify the relative expression amounts of miRNAs. Results: Compared with model group, the glomeruli matrix accumulation of the rats in HACE group (after treated for 8 and 16 weeks) was significantly improved and the urinary albumin excretion rates were decreased (P<0. 05). The miRNAs chips results showed that there were 35 differentially expressed miRNAs in control and model groups and there were 17 differentially expressed miRNAs in model and HACE groups. The RT-qPCR results showed that after treated for 8 weeks, compared with control group, the relative expression amounts of miR-1306-3p (P<0. 05), miR-672-5p (P<0. 05) and miR-3550 (P<0. 01) in the kidney tissue of the rats in model group were decreased; compared with model group, the relative expression amount of miR-672-5p in the kidney tissue of the rats in HACE group was increased (P<0. 05). After treated for 16 weeks, compared with control group, the relative expression amount of miR-21-5p in the kidney tissue of the rats in model group was increased (P
RESUMO
To study the effect of chinese herbal medicine preventing gallstone formation, morphology of livers and gallbladders as well as conjugated bile acids of the bile. 58 female guinea pigs were randomly divided into three groups. The control group was fed on normal diet; the lithogenous groups was high cholesterol diet (HCD) and the antilithic group was high cholesterol and the chinese herbal medicine capsule (13.5 g/kg). 8 weeks later the guinea pigs were killed. Liver and gallbladder were removed for light and electroscope observation. Gallbladder bile were withdrawn and gallbladder were collected. The minute construction of gallstones were observed by scanning electron microscope and gallstone components were quantified by Fourier Transform Infrand Spectros Copy (FT-IR). The morphology of liver and gallbladder were observed by light microscope and transmission electron microscope. Conjugated bile acid of biles were determined by Thin-layer Chromatograph. The effect of chinese herbal medicine preventing gallstone formation, morphololgy of livers and gallbladders as well as conjugated bile acids of the bile were also observed. We measured conjugated bile acids in all groups and found that decreased in lithogenic group and increased notably in antilithic group (P＜0.01). The gallstone formation rate was 100% when the animals were fed on HCD in lithogenic group. The rate decreased to 5.3% when the animals were fed on HCD and Chinese herbal medicine capsule inantilithic group. It indicates that changes in diet is an important factor in the process of gallstone formation and the chinese herbal medicine can prevent gallstone formation effectively.
RESUMO
Objective:In order to investigate the influence of Herba Artiemisiae Capilloais on the UDPGT activity in rat's hepat.Methods: The UDPGT activities induced by Herba Artemisae capillaris were determined by the Black's assay.Results: Herba Artemisiae capillaris increased the activity of UDPGT in rats' hepat and also increased the ratio of liver weight/body weight. Conclusions: Herba Artemisiae capillaris was able to induce the acitvity of UDPGT in rats' hepat.
