AIM: To examine the effect of protamine sulfate, lipopolysaccharide(LPS),tumor necrosis factor(TNF), epidermal growth factor(EGF) and " Bushen Huoxue Xiezhuo" (BHX) decoction on the proliferation of extracorporeal cultured rat glomerular epithelial cells (GEC). METHODS: Their action on the proliferation of rat GEC were investigated using the -TdR incorporation. Meanwhile, the serum of rats treated with BHX decoction was extracted pharmacologically and its effects on the growth of GEC were also studied. RESULTS: LPS, protamine sulfate, TNF-? and EGF could significantly inhibit the -TdR incorporation of GEC in a dose- and time-dependent manner. However, this inhibition could be efficiently reversed by the serum containing BHX decoction. CONCLUSION: GEC is one of the main target cells on which BHX decoction act, and the protection on GEC might be one of the mechanisms underlying the role of BHX decoction in preventing the progression of nephrosis.

Objective To explore the effects of ligustrazine on secretion of nitric oxide(NO) in ventricular tissues of rats under physiologi-cal condition.Methods Twenty-four normal wistar rats were divided into three groups,eight each group.The left and right ventricular tissues of each rats were divided into control group and 2 ligustrazine groups and the final concentrations of ligustrazine were 15 mg/L and 150 mg/L respectively.The ventricular tissues that had been cutting into small pieces were incubated in 37 ℃ thermostatic water bath for 4 hours with Krebs solution as supernatant.After incubation of the ventricular tissues,the spectrophotometric method was used to detect the content of NO_2~-/NO_3~-in the supernatant.Results Compared with the content of NO in control group,it was significantly decreased in the 150 mg/L ligustrazine group(P

AIM: To study the effect and the mechanism of crenulatin, an effective constituent of Chinese traditional medicine, on apoptosis of cerebral microvascular endothelial cells. METHODS: The following terminal concentrations of crenulatin were used in the study: 25 mg/L and 100 mg/L. Apoptosis of mouse cerebral microvascular endothelial cells (bEnd. 3 cell line) was evaluated by flow cytometer, immunocytochemical assay (Fas, Bcl - 2) and Western blotting (caspase - 3) after culture for 24 h. RESULTS: Compared with control group, apoptosis of bEnd. 3 cells in 25 mg/L group was significantly inhibited ( P ＜0.05), but apoptosis in the 100 mg/L group was significantly increased (P ＜ 0.05). In apoptosis inhibited group, the Fas immunocytochemical staining was weaker, the positive cells were significantly decreased ( P ＜ 0.05) and caspase - 3 expression was decreased compared with control group; however, the Bcl - 2 staining was stronger and the positive cells were significantly increased ( P ＜ 0.05). On the other hand, in apoptosis increased group ( 100 mg/L group), the changes were just opposite. CONCLUSIONS: The effect of crenulatin on apoptosis of mouse cerebral microvascular endothelial cells possesses a dual - direction change, inhibitive effect in 25 mg/L and stimulative effect in 100 mg/L group, respectively. The mechanism is related to the alterations of Fas/Bcl - 2 expression and caspase - 3 activity.

Objective To study the expression of vascular endothelial growth factor (VEGF) and microvessel density (MVD,CD34) in inoculated hepatic alveolar echinococcsis gerbil model and explore the clinical significance.Methods Sixty healthy gerbils were randomly divided into model group,control group and sham operation group.Each gerbil in both model and control groups had liver vaccination with 0.1 ml immature alveolar echinococcus protoscolex suspension or 0.1 ml phosphate buffered saline by open abdominal surgery,respectively,and the sham operation group only had abdominal surgical procedures.Gerbils were put to death on the 120th day post operation,extracted the eyeball and drawn the blood.The alveolar hydatid tissue,surrounding and distal liver tissue were removed from the model group,and normal liver tissue was collected from the other two groups.The VEGF and MVD-CD34 expression was detected by immunohistochemistry staining,Western Blot,and enzyme-linked immunosorbent assay (Elisa).Results Liver alveolar echinococcsis tissue was only observed in model group.The VEGF expression was observed as yellow or brown yellow granules located in the cytoplasma.The VEGF score and VEGF/β-actin ratio in the different parts were 5.13 ± 1.81 and 1.12 ± 0.05,4.20 ± 1.52 and 0.91 ± 0.02,2.46 ± 1.06 and 0.28 ±0.02,2.20 ±0.77 and 0.30 ±0.02,2.13 ± 1.72 and 0.25 ±0.01,respectively.The VEGF expression in different histological sites showed a gradient change,and bubble hydatid tissues had the highest VEGF expression (P ＜ 0.05).CD34 was expressed in alveolar hydatid tissue and surrounding liver tissue in model group and the CD34 positive cells was stained brown,while CD34 was mainly located in the cell membrane of endothelial cells.The CD34 scores and the CD34/β-actin ratio in the different parts were 5.06 ± 2.46 and 0.66 ±0.01,2.43 ± 1.26 and 0.58 ±0.02,and the other tissues did not have CD34 expression.The alveolar hydatid tissue had higher CD34 expression than any other tissues (P ＜ 0.05).The respective serum VEGF and CD34 level in each group was (106.17 ± 14.17)pg/ml,(38.13 ± 21.36)pg/ml,(42.88 ±17.25) pg/ml,and (1.47 ± 0.28) ng/ml;(0.82 ± 0.12) ng/ml,(0.72 ± 0.16) ng/ml,both are higher in model group than those in the other groups with statistical significance (P ＜ 0.05).Conclusion Angiogenesis is detected in gerbil alveolar hydatid tissues,which might be involved in the infiltrating growth of alveococcus.
