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 observe the effect of combination of Rhizoma Coptidis (RC) and Fructus Evodiae (FE) in various proportions on rat models with heat syndrome. [Methods] Rat models with heat syndrome were set up by gastric infusion of Radix Codonopsis Pilosulae and Radix Astragali seu Hedysari. Fifty rats were allocated to five groups: normal control group (Group A), model group (Group B), model rats treated with RC and FE at the proportion of 6∶1 (Group C), model rats treated with RC and FE at the proportion of 2∶1 (Group D) and model rats treated with RC and FE at the proportion of 1∶1 (Group E). [Results] Ultrastructure of hepatic cells were improved in Group C, Group D and Group E. Indexes of heat syndrome such as temperature, serum corticosteroid (Cor) level and 17 - hydroxycorticosteroid (17-OHCS) content in homogenate of adrenal glands were decreased in Group C and Group D but stayed unchanged in Group E as compared with Group B ( P
ABSTRACT
[Objective] To optimize the conditions of the extracting process of Hujin Granules. [Methods] The orthogonal design was applied. With the total emodin and the total anthraquinone (TA) content as the parameters for the alcohol-extraction, the concentration of alcohol, the volume of solvent and the extracting time were used for optimization of alcohol-extraction. With the total polysaccharide (TP) as the parameters for water-extraction, the soaking time, the volume of water and the extracting time were used for optimization of water-extraction. [Results] The optimum conditions of alcohol-extraction were: extracting with 70% alcohol 245 mL for 2 hours and extracting twice. The optimum conditions of water-extraction were: extracting with 80 mL water (not for soaking) for 1.5 hours, extracting 3 times. [Conclusion] The results indicate that the extracting process is rational and feasible, and can provide evidence for the extracting process of Hujin Granules.
ABSTRACT
Objective To investigate the anti- inflammatory and analgesic a ctions of Huangqi Guizhi Wuwu Decoction (HGWD) and its compositions and to study its rule of compatibility.Methods Analgesic action of HGWD and its compositio ns were observed by hot- plate method and acetic- acid- induced body twist me thod. Anti- inflammatory action of HGWD and its compositions were observed on t he models of xylene- induced auricular swelling in mice, celiac capillary perme ability in mice, cotton- induced granuloma in rats, albumem- induced arthritis and adjuvant arthritis in rats.Results HGWD and its drug pairs could inhibit the acute inflammation induced by albumen and xylene and rat adjuvant arthriti, decrease the celiac capillary permeability, inhibit the proliferation of granu loma, increase the pain threshold in mice and reduce the frequencies of body tw ist induced by acetic acid.Conclusion HGWD has significant anti- inflammatory and analgesic actions, so does single drug; Radix Astragali alone, but when Ra dix Astragali is used with the other drugs in HGWD, its effect can be enhanced.
ABSTRACT
The anti-aging effect of Yang Shou Dan (YSD) was studied. It was shown that YSD could obviously increase the activity of superoxicde dismutase (SOD) in erythrocyte, decrease lipid peroxides (LPO) in serum and in liver tissue and reduce the content of lipofucin in myocardium of mice. It could also prolong the mean life span, the half lethal period and the longest life time of drosophila melanogater. It is suggested that YSD exerts an anti-aging effect to a certain extent.
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 pharmacodynamic effect of Reganling Oral Liquid(RGL) in treating wind heat epidemic syndrome. Methods: After RGL was administered ig to experiment animals, we observed its antifebrile effect by using pathologic hectic rabbit caused by typhoid bacterin and pathologic hectic rat caused by injection of 2,4 dinitro phenol, anti inflammation effect by weighing the tampon acestoma in rat, anti anaphylaxis effect by using delay anaphylactoid mice caused by injection of 2,4 dinitrochloro benzene. The Liquid Tube Observing Method was used to investigate the bacteriostatic activity of RGL on eight kinds of germina in vitro . Results: RGL could evidently inhibit the raising of animal heat caused by bacterin and chemical, and also could markedly restrain the weight of tampon acestoma in rat and delay anaphylactoid in mice. RGL also had remarkably bacteriostatic activity on eight kinds of germina in vitro which mainly caused wind heat epidemic syndrome. Conclusion: RGL had the evident effects of antifebrile, anti inflammation, anti anaphylaxis and bacteriostatic activity in vitro .
ABSTRACT
Having referred the Chinese academic publications on TCM during the last decade ,we summarized the researches in Angelica Decoction (AD), which included immunoregulatory, circulatory system, the basis of decoction composition, anti-oxidation, liver injury and compaibility. AD can improve the immunity action, meliorate abnormal circulation, and also has the effects of anti-oxidation and protection of liver injury. Futher study on AD should be focused on its mechanism and material basis in the future.
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.
