    Objective:The quantitative determination of bacterial endotoxin in metronidazole injection was introduced and
    its relative problems were discussed.Methods:The bacterial endotoxin in metronidazole injection was quantitatively
    determined by the bacterial endotoxin test and affinity membrane isolating method, 0.2% metronidazole injection diluted
    5time was determined, 0.5% metronidazole injection diluted 13time was determined (sensitivity of tachypleus
    amebocyte lysate was 0.125 EU/ml).Results:Affinity membrane isolating method was similar to bacterial endotoxin
    test.Conclusion:Affinity membrane isolating method is accurate and dependable, simple and quick in clinical application.

    Objective:To evaluate the effect of stevioside against hypertension.Methods:The characterically hypotensive effect of intravascular stevioside on concious and anesthetized spontaneously hypertensive rats was studied. The concious spontaneously hypertensive rats were given intravascular stevioside 50200 mg/kg, the anesthetized rats 25398 mg/kg, and the dogs 16159 mg/kg.Results:The Stevioside reduced SBP and DBP with a dose dependent, the hypertensive duration are extend, and the effect of DBP reduced was superior to that of SBP. The doseeffect relationship was significant in the spontaneous rats received intravascular stevioside 63251 mg/kg and the dogs received 40159 mg/kg.Conclusion:Stevioside has exactly hypotensive effect, its effect of DBP reduced is superious to that of SBP reduced.

    Objective:To evaluate the value of tinidazole (TNZ) injection in the prevention and treatment of obstetrical and gynecological patients with anaerobic infecitons in comparison with metronidazole (MNZ) injection.Method:A dose of 800 mg/200 ml TNZ or 1 000 mg/200 ml MNZ were intravenously infused daily. The gynecological patients received the treatment for 5 days, and the obstetric patients for 3 days. The isolation and culture for anaerobes were performed before and after treatment. At the same time, antibacterial activity in vitro of TNZ against 3 reference strains and 107 anaerobes isolated from patients was examined and compared with the activity of MNZ.Results:The eradication rate or obvious reduction rate of anaerobic bacteria in TNZ group and MNZ group were 91.0% and 44.0%, respectively. The total clinical effective rate of both injections were 94.0% and 82.0%, respectively. The results showed that the clinical efficacy of TNZ against anaerobes was higher than that of MNZ (P<0.01). The both activities in vitro were confirmed also that TNZ was better than MNZ, MICs and MBCs were 0.3950.00 mg/L and 0.78100.00 mg/L, respectively.Conclusion:TNZ is more effective than MNZ in the prevention and treatment of anaerobic bacterial infection in female genital tract.

    Objective:The action mechanism of ForbidFatStar capsule on a reduction of blood lipid and clinical effect.Methods:Total serum cholesterol and trighlyceride of hyperlipemia in rats and blood rheology in rabbits were experimentally observed.Results:There were significiant effect for reducing the total serum cholesterol and triglyceride in human and animal, and the effect of experimental group was superior to controlled group.Conclusion:This capsule can be used for prevention and treatment of patients with hyperlipemia. The obvious toxic and side effect have not been found.

    To confirm the effect of taurine on serum lipids in rats with nephrotic syndrome (NS).Methods:Effects of Taurine on hyperlipemia were observed by the model of doxorubicine plus NS after one side nephrotomy.Results:Taurine could significantly decreased the concentrations of total cholesterol, total triglycerides, low density lipoprotein, and very lower density lipoprotein compared with the controlled group (P<0.05).Conclusion:Taurine has the effects of regulating lipid metabolism, and partly maintaining renal function in rats with nephrotic syndrome.
