OBJECTIVE: To evaluate the therapeutic effect of Zangfukong suppository on the experimental vaginitis.METHODS:The experimental rats were equally assigned to 6 groups: normal control group,model control group,gyno-daktarin(0.12 g?kg-1) group,three Zangfukang groups(0.33 g,0.17,and 0.08 crude drug? kg-1).Candida albicans solution was injected into the vigina of the estrous rats to establish colpomycosis model.The effect of Zangfukang suppository on the infection rate of candida albicans was observed.The bacterial vaginitis model was established by injecting the mixture bacteria of Neisseria gonorrhoeae,staphylococcus aureus and escherichia coli into the vagina of rats,and the effect of Zangfukang suppository on the gonococcal infection rate.RESULTS: After local application of Zangfukang suppository for 7 consecutive days for treatment of colpitis mycotica of rats,the infection rates of candida albicans were significantly lower in medium-dose and high-dose groups than in the model control group(P

In this research,we chiefly explored a new fast test method--microtox technology to evaluate the comprehensive toxicity of Shen Mai injection.We investigated characteristic parameters of vibrio fischeri (CS234) under different conditions in the pursuit of the optimum test parameters of the reliable method;and then locked the best parameters for Shen Mai injection assay with the products from different manufacturers by microtox fast test.As a result,the optimum reaction condition included 0.9 mL recovery liquid in each freeze-dried vial and 50 μL bacteria suspension of each sample within 2 mL solution in aggregate with 10-mins detection after adding bacteria suspension which pH value ranging from 5 to 10 and luminous intensity from 0.8 to 1.2 million in 10 mins.The relative standard deviation values of replication experiment and precision test were all below 15％.Under this optimum detection condition,it was found that the EC50 values were 35.60％,92.34％ and 146.57％,differing among the samples from three representative drug manufacturers,respectively (P ＜ 0.01).In conclusion,the concentration-effect relationship of Shen Mai injection existed in the toxicity assessment of vibrio fischeri with various ECs0 values from the three manufacturers.These results suggested that biological detection standards of Shen Mai injection presented great growth potential.Microtox-based fast test in the evaluation of comprehensive toxicity of ShenMai injection showed favorable application prospects over controlling the quality of different sources of products.

Objective To investigate the therapeutic effect of the sandwich method (medical glue +gelatin sponge+medical glue) in the repair of spinal dura mater to prevent the cerebrospinal fluid leakage.Methods From February 2007 to June 2011,54 patients with spinal subdural tumors underwent excision of tumor in our hospital.According to manner of repairing spinal dura mater,all patients were classified into two groups:routine group and sandwich group.There were 16 males and 7 females with an average age of 45.2±7.2 years in the routine group,while 19 males and 12 females with an average age of 44.2±6.4 years in sandwich group.In routine group,the spinal dura mater was repaired through running locked suture.In sandwich group,the spinal dura mater was repaired through running locked suture,painting medical glue around the dural incision,covering with gelatin sponge,and painting medical glue on the surface and margin of gelatin sponge successively.Results Compared with the routine group,the total volume of postoperative drainage in sandwich group decreased significantly on the very day,the first day,the second day,and the third day,and the incidence of cerebrospinal fluid leakage decreased significantly.Before discharge,hydrops happened in 3 cases in the routine group,and got well through aspiration,continuous pressure by sandbag,and prone position.Three months after operation,5 cases from the routine group got deep hydrops under the incision and no treatment was applied to them.There was no obvious abnormality in the sandwich group.Conclusion The sandwich method can improve the repair effect of spinal dura mater injury,reduce the volume of postoperative drainage,and decrease the incidence of cerebrospinal fluid leakage
