The crude toxin was extracted from hypha and culture solution of Phyllosticta commelimecola through three different polarity solvent: benzinum, puncificatum ethyl acetate and chloroform. The result indicated that the toxin secreted by Phyllosticta commelimecola not only was in hypha but also in culture solution and the extracting effect of ethyl acetate was the best. The soybean median and PSK media can be respectively used as solid and liquid culture media to produce toxin and grow mycelium. The optimal cultural conditions for producing toxin were temperature 32℃,cultured period 14d, cultured ways shaking of 150r/min.

Objective To study the effects of angiotensin converting enzyme inhibitor benazepri1 on apoptosis and the expression of Fas and FasL in the kidney of rats with adriamycin-indued nephritic glomeruosclerosis.Methods After uninephrectomy and the injection of adriamycin induced rats model with glomerulosclerosis, benazapril(6 mg/kg) was delivered daily by gavage to the rats in therapeutic groups for 12 weeks.Apoptosis was examined by means of terminal-deoxynucleotidyl trans ferase mediated d-UTP nick end label ling(TUNEL) and immunohistochemistry was utlized to detect the expression of Fas and FasL.Software of pathological analysis quantitated the level of Fas and FasL.Results Compared with those of the control group, the kidney of model group had moresevere glomerulosclerosis, much more apoptotic cells and higher level of exprssion of Fas and FasL. The degree of glomeruloscleroais, the nuxner of apoptotic cells and the level of expression of Fas and FasL were ameliofated by benazepril treatment.Conclusion Benazepril may suppress the excessive apoptosis of kidney cell by lowering the expression of the protin correlatng apoptosis Fas and FasL,so as to postpone the process of glomeruosclerosis.

OBJECTIVETo study the bioactive constituents of the fresh rhizome of Pinellia ternata, and provide the scientific basis for quality control.
METHODVarious chromatographic techniques were used to separate and purify the chemical constituents, and their chemical structures were determined on the basis of physical-chemical properties and spectroscopic analysis. The inhibitory effects of the isolated compounds on tumor necrosis factor (TNF)-alpha production in the peritoneal macrophages of mice stimulated with lipopolysaccharide (LPS) were assayed in vitro by microplate colorimetric method.
RESULTNine compounds were isolated and identified as (E)-p-coumaryl alcohol (1), 3, 4-dihydroxycinnamyl alcohol (2), ferulic acid (3), lariciresinol (4), erythro-guaiacylglycerol-beta-O-4'-sinapyl ether (5), dehydrodiconiferyl alcohol (6) , isolariciresinol (7) , sachaliside 1 (8) and coniferin (9). The inhibitory effect of compounds 1, 2, 3, 8, and 9 were 24.1% , 57.6% , 40.2% , 82.7% , and 62.0% , respectively, against the TNF-alpha production in the peritoneal macrophages of mice stimulated with LPS at a concentration of 10(-5) mol L(-1) in vitro.
CONCLUSIONThe compounds 1, 2 and 4-8 from genera Pinellia Ten. and compound 9 from P. ternata were isolated for the first time. The compounds 1, 2, 8 and 9 were phenylpropanoids, and 4-7 were lignanoids. The anti-inflammatory effects of the rhizome of P. ternata might relate at the least to compounds 1, 2, 3, 8 and 9.

To investigate the effects of oleanolic acid (OA) on the proliferation, migration and the formation of tube-like structure in human vascular endothelial cells (HUVECs). MTT assay, flat plate scarification, Transwell plates and matrigel-induced tube formation assay were performed to detect the effects of OA on proliferation, migration and tube formation. MTT assay showed that the inhibition rates of HUVECs treated with 60 and 100 microg x mL(-1) of OA for 24 h were 19% and 83% respectively. Treatment of HUVECs significantly inhibited the cell migration in a dose-dependent manner. The vascular indexes of HUVECs treated with 40 and 60 microg x mL(-1) OA were 33% and 20% respectively. Western blotting analysis showed that treatment of the cells with OA significantly attenuated the expression and secretion of VEGF. Additionally, VEGF could in part reverse the effects of OA on migration and tube formation of HUVECs. In conclusion, OA inhibits the proliferation, and VEGF plays an important role in OA induced decreased migration and tube formation of HUVECs.

OBJECTIVEUsing doubly labeled water method to validate the colmputer science application's activity monitor (CSA) in assessing physical activity of free-living adults in Beijing, in order to develop equations to predict total daily energy expenditure (TEE) and activity related energy expenditure (AEE) from activity counts (AC) and anthropometric variables.
METHODSA total of 72 healthy adults (33 males and 39 females, mean age 43.6 +/- 4.0 yr) were monitored for 7 consecutive days by CSA. TEE was simultaneously measured using doubly labeled water method. Average AC (counts/min(-1)) was compared with TEE, AEE and physical activity level (PAL).
RESULTSPhysical activity determined by AC was significantly related to data on energy expenditures: TEE (r = 0.31, P < 0.01), AEE (r = 0.30, P < 0.05), and PAL (r = 0.26, P < 0.05). Multiple stepwise regression analysis showed that TEE was significantly influenced by gender, fat-free mass (FFM) or BMI and AC (R(2) = 0.52 - 0.70) while AEE was significantly influenced by gender, FFM and AC (R(2) = 0.25 - 0.32).
CONCLUSIONAC from CSA activity monitor seemed a useful measure in studying the total amount of physical activity in free-living adults while AC significantly contributed to the explained variation in TEE and AEE.
