3T3-LI preadipocytes were induced to differentiate and 3T3-L1 adipocyte or preadipocytes were incubated with oleate or palmitate overnight.RT-PCR was used to measure adiponectin receptor(AdipoR)1 and AdipoR2 mRNA levels.The results showed that the AdipoRl and AdipoR2 expressions were differentiation- dependent.Oleate only suppressed AdipoR mRNA expression in preadipocyte but not in adipocyte.However,high concentration of palmitate reduced AdipoR mRNA expression in both 3T3-LI preadipocyte and adipocyte.

Lactic acid production and antagonistic property of five strains of LAB isolated from piglet intestine were investigated. The results showed that among all strains L5 exhibited the most rapid production and highest amount of lactic acid in the culture. Consequently, the pH in L5 culture showed the fast decline, with the final value significantly lower than those of other cultures. Strain L1 showed the least production of lactic acid and highest pH among all strains. Culture supernatants of the five strains showed different degrees of antagonistic effect against pathogenic E. coli K88, K99, 987P, O141, E1, and S. aureus. When taking out the effect of the acid, the culture supernatants still showed 22%~53% inhibitory effect, suggesting that the bacteria produced other inhibitory substances apart from lactic acid. The inhibitory effect of the culture supernatant was above 92% after heat treatment and above 85% when treated with proteases.

OBJECTIVETo compare the therapeutic effect of Compound Recipe Gengniankang ( GNK) with that of hormone replacement treatment (HRT) on climacteric female rats with osteoporosis, and to investigate the roles of estrogen and estrogen receptors in the mechanism of osteoporosis.
METHODSClimacteric female rats with osteoporosis were chosen and divided into three groups (GNK group, HRT group and control group). Apoptosis of ovarian granulose cells was measured by terminal-deoxynucleotidyl transferase mediated nick end labeling (TUNEL) assay. Serum level of estradiol (E(2)), follicle stimulating hormone (FSH), luteinizing hormone (LH) were determined by the method of radioimmunoassay (RIA). Reverse transcriptase polymerase chain reaction (RT-PCT) technology was used to evaluate the expression of estrogen receptor (ER) in bone. Bone mineral density (BMD) was measured by double energy X-ray absorption (DEXA).
RESULTSIn the climacteric rats, BMD, serum E(2), ER mRNA expression in bone decreased remarkably, and serum FSH, LH and apoptosis of ovarian granulose cells increased obviously. After treating with GNK, all the indexes were reversed except serum E(2). The increase of E(2) was not significant.
CONCLUSIONGNK is effective on climacteric osteoporosis female rats. Its role is performed not by increasing serum E(2) but by enhancing ER in the bone and inhibiting apoptosis of ovarian granulose cells. GNK can deter further exhaustion of ovarian function.

To study the pharmacokinetic process of Danshensu in cerebal ischemia injury model rats and the correlation with its anti-cerebral ischemia effect. In this study, the middle cerebral artery occlusion (MCAO) model was established, in which all of the rats were intravenously injected of Danshensu at a single dose of 40 mg x kg(-1). The HPLC-DAD method was applied to determine the plasma concentration of Danshensu at different time points and draw the drug-time curve. Meanwhile, the superoxide dismutase (SOD) and the lactate dehydrogenase (LDH) activity were determined to draw the time-effect curve. The DAS 3.2. 6 software was used to process the data, analyze their correlation, compare the pharmacokinetic difference between model and normal rats after the administration of the same doses of Danshensu and the changes in pharmacodynamic indicators of model rats after the administration, and evaluate the effect of Danshensu in treating the cerebral ischemia disease. According to the results, the pharmacokinetic processes of Danshensu in the cerebral ischemia-reperfusion and normal rats were consistent to the two-compartment model. The main pharmacokinetic parameters were: t1/2alpha were (0.267 +/- 0.026), (0.148 +/- 0.020) h;t1/2beta were (1.226 +/- 0.032), (1.182 +/- 0.082) h; AUC0-infinity were (42.168 +/- 4.007), (26.881 +/- 1.625) mg x L(-1) x h. After the cerebral ischemia-reperfusion, the activity of SOD decreased and the activity of LDH increased. Danshensu could inhibit the decrease in the SOD activity and the increase in the LDH activity within a certain period of time. This indicated that Danshensu could stay longer in cerebral ischemia-reperfusion rats than in normal rats and eliminated more slowly, which reflected the rationality of Danshensu in the clinical treatment of cerebral ischemia diseases. Danshensu's effect against the cerebral ischemic injury may be related with its level in vivo. Its plasma concentration is positively related to the SOD activity and negatively related to the LDH activity.

OBJECTIVETo observe the effect of compound gengniankang (GNK) in regulating the endocrine and immune functions in aged female rats.
METHODSAged female rats with osteoporosis were selected as the object for observation and healthy young rats were taken for control. Animals were administered by GNK and nilestriol respectively, through gastric perfusion, for 3 months to observe the therapeutic effect of drug treatment on osteoporosis and the regulatory effect on endocrine and immune function. Bone mineral density (BMD) was measured by double energy X-ray absorption technique, serum levels of estradiol (E2), follicule-stimulating hormone (FSH) and luteinizing hormone (LH) were determined by RIA, T-cell subsets and apoptosis in spleen were detected by flow cytometry.
RESULTSIn aged rats with osteoporosis, the BMD decreased, serum level of E2 lowered, FSH and LH levels raised, splenic CD4+, CD4+/CD8+ significantly decreased and T-cell apoptosis rate significantly elevated. GNK could increase the BMD, lower the FSH and LH levels, but showed no significant effect on E2 level. It could increase the CD4+ and CD4+/CD8+ ratio to nearby the normal range, and reduce the apoptosis of T-cells.
CONCLUSIONGNK has therapeutic effect on osteoporosis in aged rats, and is able to regulate the endocrine and enhance the immune function in organism.

OBJECTIVETo observe the effect of ginsenoside Rg1 on behavior and hippocampal amino acids in depressive-like rats.
METHODSD rats were randomly divided into 5 groups: control, model, fluxetine, low dose ginsenoside Rg1 and high dose of ginsenoside Rg1. The chronic unpredictable mild stress (CUMS) was performed to induce depressive-like animal model. Fluxetine group was orally given fluxetine in dose of 10 mg x kg(-1) for 21 days, low dose ginsenoside Rg1 group was orally given ginsenoside Rg1 in dose of 20 mg x kg(-1) for 21 days, high dose ginsenoside Rg1 group was orally given ginsenoside Rg1 in dose of 40 mg x kg(-1) for 21 days. The control and model group was orally given saline for 21 days. The sucrose consumption was detected before and after the CUMS procedure. The horizontal and vertical activities of rats were determined by open-field test. HPLC was adopted to detect the contents of amino acids in hippocampus.
RESULTThe sucrose consumption, horizontal and vertical activities in CUMS rats were decreased compared with those in control group. Compared with control group, the contents of glutamate (Glu) and aspartate (Asp) in hippocampus of CUMS group were increased, while the gamma amino butyric acid (GABA) and taurine (Tau) were decreased. Ginsenoside Rg1 treatment significantly increased the CUMS-induced decrease in sucrose consumption, horizontal and vertical activities. Administrated with ginsenoside Rg1 also decreased Glu and Asp and increased the GABA and Tau in hippocampus in a dose dependent manner.
CONCLUSIONGinsenoside Rg1 could alleviate the behavior changes of depressive-like rats, which might be related to regulate the levels of amino acids in hippocampus during CUMS and prevent the neuro-toxicity of excitatory amino acids.
