ABSTRACT
Objective To observe the therapeutic effects of Liuwei Shunji Capsule on survival state, visceral hypersensitivity, the content of 5-HT of model rats with liver depression and spleen deficiency-type irritable bowel syndrome (IBS), and explore its mechanism.Methods SD rats were randomly divided into normal group, model group, pinaverium bromide group and Liuwei Shunji Capsule of high, medium and low dose groups. Senna with restraint stress was used in duplicating liver depression and spleen deficiency-type IBS model. From the second day after the model was established, each drug treatment group was administered with corresponding drugs once a day for two weeks. The effects of Liuwei Shunji Capsule on survival state, visceral hypersensitivity, the content of 5-HT in serum and hypothalamus were observed.Results Compared with model group, Liuwei Shunji Capsule could raise weight growth rate of model rats with liver depression and spleen deficiency-type IBS (P<0.05), improve their diarrhea, fatigue demeanor, fur quality, irritability and other symptoms, significantly decrease their visceral hypersensitivity, the content of 5-HT in serum and hypothalamus (P<0.01).Conclusion Liuwei Shunji Capsule can effectively improve survival state and intestinal disorders of rats with liver depression and spleen deficiency-type IBS, and the mechanism of treatment could be realized through regulating 5-HT level.
ABSTRACT
Objective: To observe the therapeutic effects of effective compounds which were extracted from TongMai. Methods: SD rats experimential model with MsPGN were induced by subcutaneously injection rabbit anti-rat thymocyte serum(ATS) and forced swim. The rats were respectively ig with different dose(1.2,0.6,0.3 g'kg-1) of effective compound of TongMai for 4 weeks. Then the proliferative degree of mesangium was examined by HE stain, PAS stain and immunfluorescent respectively. Mesagium area proportion in glomerular capillaries area was calculated using image analyzing system. The expression of PCNA in the glomeruli was examined by immunohis to chemistry. Results: The effective compounds of TongMai can control the hyperplasia of the glomemlar mesangial cells (GMG)and the mainifold of the mesangial matrix, and prevent the deposit of IgG in mesangium. The proportions in glomerular capillaries area in model control group were significantly higher than that in the treatment groups; The express of proliferative cell nuclear antigen (PCNA) were ascended either. Conclusion: The effective compound of TongMai can improve the damage s of pathology in glomerular.
ABSTRACT
Objective To study the effect of Aloe polysaccharides (AP) on the thymocytic apoptosis and cell cycle in ? - ray irradiated mice. Methods Single- cell thymocytes suspension was sampled at different time points to observe the thymocytic apoptosis and cell cycle by flow cytometry. DNA ladders were tested by 1.8 % agarose gel electrophoresis. Transmission electron microscopy was used to examine the ultrastructure of thymocytes. Results Pre- treating with AP (50 mg/kg,ip) 30 min before irradiation could significantly decrease the percentages of apoptotic thymocytes in? - ray irradiated mice 4 h, 8 h and 12 h after irradiation, increase the percentage of thymocytes at G0/G1 phase and reduce the percentage of thymocytes at G2/M phase. It could also lessen the DNA ladders and reduce the number of apoptotic bodies. Conclusion The protective effects of AP on the thymocytes in ? - ray irradiated mice is related with the alleviation of the disorder of cell cycle and the inhibition of the apoptosis of thymocytes.
ABSTRACT
Objective To study the effect on proliferation of glomerular mesangial(GMC) cell by the dose compatible proportion between Radix Astrsgali and Radix Notoginseng in Tongmai Oral Liquid(TMOL) so as to select the optimal dose proportion.Methods We used serological pharmacological methods to prepare Decoction of Tongmai of different dose proportions and assay its effect on the proliferation of GMC to confirm the best dose compatible proportion between Radix Astrsgali and Radix Notoginseng of Decoction of Tongmai.Results Both TMOL and the different proportions between Radix Astrsgali and Radix Notoginseng(6∶1,3∶1,1.5∶1) of Decoction of Tongmai could inhibit the proliferation of GMC cultured either in fetal cow serum(FCS) or in FCS plus lipoplysaccharide.The inhibitory effect of Decoction of Tongmai(3∶1) group was better than both Decoction of Tongmai 6∶1 and Decoction of Tongmai 1.5∶1.Conclusion The dose compatible proportion between Radix Astrsgali and Radix Notoginseng in TMOL was reasonable.
