Shenfukang is an effective formula for glomerulonephritis applied in the first affiliated hospital of Guangzhou University of TCM. It is composed of Radix Folium seu Flos Tripterygii wilfordii, Radix Astragali seu Hedysari, Radix Notoginseng, Herba Leonuri, etc.. Glomerulonephritis rat model was induced by cationized bovine serum albumin (C-BSA) according to Border's method and was used to observe the pharmacological action of Shenfukang. The results showed that Shenfukang can eliminate urine protein, increase the levels of serum protein, albumin (A), globulin (G) and A/G ratio, and decrease the contents of serum cholesterol, creatinine and urea nitrogen. It can also counteract the increase of plasma TXB 2 and the decrease of plasma 6-keto-PGF 1? . LD 50 of Shenfukang for mice is 174.34?36.74?g/kg which is much larger than that of Tripterygium wilfordii (29.73?6.46?g/kg for female mice and 101.74?10.93?g/kg for male mice). It is indicated that Shenfukang exerts a protective effect on renal function and reduces toxicity of Tripterygium wilfordii.

The purification of SND was evaluated by chemical and pharmacological methods. Results: The thin layer chromatograms, high performance liquid chromatograms of the SND purification and those of SND were almost the same; also the SND purification can significantly promote the content of nitric oxide (NO) in serum of mice treated by Metaraminol. Conclusion: The SND purification can keep the active ingredients of SND.

Objective: To study the correlation of pharmacokinetics(PK) and pharmacodynamics(PD) of Sini Decoction (SND) (Radix Aconiti Praeparata, Rhizoma Zingiberis, Radix Glycyrrhizae, etc.) and reveal the compatibility of SND. Methods: Using the drug serums from the same source, we determined the plasma concentration in vivo in dog and the pharmacological effects at the same time inspected by the contents of aconitine type alkaloids and nitric oxide (NO). Results: The data of PK and PD can be both described by one compartment open model with first order absorption in vivo in dog and the parameters of two methods are similar. The results show that the effective fraction of SND gives a prompt and lasting effect in accordance with characteristic function of SND. Conclusion: A good correlation exists in SND of the parameters between pharmacokinetics and pharmacodynamics.

Objective To examine the therapeutic effect of Kummerowia striata (KS) on IgA nephropathy (IgAN) rats.Methods Sixty SD rats were equally randomized into 6 groups after adaptive feeding for 3 days:blank control group,model control group,tripterygium glycosides (TG) group (in the dose of 0.0165 g/kg),and high-,middle-and low-dose KS groups (in the dose of 16.0,8.0,4.0 g/kg respectively).IgAN rat model was established with bovine serum albumin (BSA),lipopolysaccharide (LPS) and carbon tetrachloride.After modeling,rats except those in blank control group received gastric gavage of corresponding drugs for 10 continuous weeks.Levels of 24-hour proteinuria and hematuria in each group were measured,serum levels of total protein (TP),serum albumin (ALB),aspartate aminotransferase (AST),and alanine aminotransferase (ALT) were tested.The pathological changes of renal tissue were observed under light microscope by HE staining.Results Water decoction of KS could significantly decrease the proteinuria and hematuria levels,and reduce renal pathological changes of IgAN model rats.However,water decoction had no effect on indicators of liver function such as TP,ALB,AST,and ALT in IgAN rats.Conclusion KS has certain therapeutic effect on IgAN model rats.

Objective To investigate the sedative and hypnotic effects of Ganoderma lucidum brewage(GLB).Methods The NIH mice were given with gavage of GLB 0.06,0.12,and 0.24g/kg per day respectively for 15 days.The spontaneous motion,the sleeping time induced by pentobarbital sodium in subthreshold dosage and threshold dosage,and the number of mice subjected to pentylenetetrazol-induced convulsion were observed.Results GLB can reduce the spontaneous motion,significantly longthen the mice sleeping time of pentobarbital sodium in threshold dosage and increase the number of sleeping mice under subthreshold dosage of pentobarbital sodium.GLB was synergic with pentobarbital sodium,and antagonized pentylenetetrazol-induced convulsion in a dose-dependent manner.Conclusion GLB possesses obvious sedative,hypnotic and anticonvulsive effects.

[Objective] To observe the pharmacological action of Ganoderma Lucidum Brewage (GLB) in decreasing blood lipid. [ Methods ] Eighty rats were randimized into 8 groups: blank control (Group A), model ( Group B) high-dose GLB ( Group C), moderate-dose GLB ( Group D), low-dose GLB ( Group E), Ganoderma Lucidum Decoction (Group F), Ganoderma Lucidum Capsule (Group G) and Xuezhi Kang (Group H). So did the mice. Hyperlipidemia mouse models and rat models were induced by yolk and high-fat diet respectively. Effect of GBL in various doses to decrease blood lipid was observed in the two kinds of hyperlipidemia models and was compared with that of Xuezhi Kang, Ganoderma Lucidum Decoction and Ganoderma Lucidum Capsule. [Results] GLB could decrease the serum contents of triglycerides and cholesterol both in model mice and model rats (P

AIM: To study the effects of Zhongjingweiling Capsule (Fructus Amomi, Cortex Cinnamemi, Rhizoma Alpiniae Galangae, Fructus Foeniculi, Radix Glycyrrhizae, etc.) on analgesia, anti inflammation and gastrointestinal peristalsis inhibition. METHODS: The effect of analgesia was tested by the method of writhes and hot plate on mice. The effect of anti inflammation was tested by injecting acetic acid and implanting cotton pellet and xylene into mice. RESULT: Zhongjingweiling Capsule effectively inhibited the swelling of mouse pinna induced by xylene and the increase of peritoneal capillary permeability caused by the acetic acid injected into mice. The capsule also decreased the proliferation of granuloma caused by implantation cotton pellet significantly and had an abirritant effect on the algesia induced by acetic acid and hot plate. Besides, it effectively inhibited the gastrointestinal peristalsis. CONCLUSION: Zhongjingweiling Capsule is an effective medicine in anti inflammation, analgesia, and gastrointestinal peristalsis inhibition.

[Objective] To observe the counteractive action of cyclovirobuxinum D (Cvb-D) for myocardial ischemia and to explore its possible mechanism. [Methods] Sixty SD rats were randomized into blank control group, Cvb-D groups in the dosage of 2.2, 1.1 and 0.55 mg? kg-1 ? d-1 respectively, isosorbide dinitrate group (25 mg? kg-1 ?d-1). The blank control group was treated with distilled water and the other groups were treated with the corresponding drugs by gavage according to the experimental design for 30 days. One hour after the last medication, pituitrin (1.5 U/kg) was injected into the caudal vein of the rats except the blank control to induce coronary artery spasticity myocardial ischemia. After that, electrocardiogram (ECG) was recorded, plasma superoxide dismutase (SOD) activity, malonyldialdehyde (MDA), lactate dehydrogenase (LDH) and phosphocreatine kinase ( CPK) levels were detected. [ Results ] The incidence of ischemic changes in ECG was decreased, plasma SOD activity increased and MDA, LDH and CPK levels lowered in Cvb-D groups as compared with those in the model group (P
