BACKGROUND: In order to improve the medication safety and remove export obstacles of Chinese preparations contained heavy metal and arsenide (cinnabar, realgar), it is necessary to carry on the evaluation on the efficacy and safety of cinnabar and realgar. At present, it has not been clear concerning to the pharmacodynamic mechanism of cinnabar and realgar in compound prescriptions yet.OBJECTIVE: To study the differences in cinnabar and realgar in angong niuhuang wan in the organism physiologically and pathologically so as to probe into those pharmacodynamic mechanism.DESIGN: A randomized and controlled trial.SETTING: Institute of Clinical Pharmacology of one university.MATERIALS: The experiment was performed in Institute of Clinical Pharmacology of Guangzhou University of Traditional Chinese Medicine in January 2003. Totally 51 male SD rats weighted varied from 250 g to 300 g were employed, provided by Experimental Animal Center of First Military Medical University of Chinese PLA.METHODS: SD rats were randomized into 6 groups(8-10 rats/group),named as normal group, normal & angong niuhuang san (integral recipe) group(278 mg/kg), normal & cinnabar and realgar omitted angong niuhuang san(disassembled recipe) group(222.7 mg/kg), cerebral edema model group(ligature on unilateral carotid artery by injection of pertussis bacilli (PB), 2 500 million/kg), model & integral recipe group (medication 278 mg/kg was done 1 hour before model preparation), model & disassembled recipe group(medication 222.7 mg/kg was done 1 hour before model preparation) . Five hours later after once medication(4 hours later after PB injection in model group), blood was collected and brain homogenate was prepared.MAIN OUTCOME MEASURES: Brain tissues, serum lactate dehydrogenase(LDH) activity and percentage enzyme activity of lactate dehydrogenase isoenzymes (LDH1-5).RESULTS: Compared with normal group, the general activity of LDH in normal & integral recipe group and normal & disassembled recipe group was significantly improved by 32.4% to 38.4% ( P ＜ 0.05); percentage enzyme activity of LDH1,2 was significantly increased( P ＜ 0.01 ), and that of LDH4, 5 was reduced( P ＜0.01) . Except LDH5, there were no significant differences in enzyme activity of isoenzymes in two groups. Compared with model group, the general activity of LDH in model & integral recipe group and model & disassembled recipe group was significantly improved by 23.4% to 38.5% ( P ＜ 0.01); percentage enzyme activity of LDH5 was significantly increased( P ＜ 0.01 ), there were no significant differences in two groups. In model & integral recipe group, percentage enzyme activity of LDH2,3 was significantly decreased( P ＜ 0.01), and that of LDH1,4 was no significant change. In model & disassemble recipe group, percentage enzyme activity of LDH1,4 was significantly reduced( P ＜ 0. 05, 0.01 ) and that of LDH2,3 was no significant change.CONCLUSION: In normal physiological state, angong niuhuang san produces a certain injuries on cardiac muscle and kidney. In pathological state of infectious cerebral edema, both integral and disassembled recipes inhibit LDH enzymes that have been over-activated, but the significant differences did not presented between both. Cinnabar and realgar in compound prescript provide the effects in various degrees on levels of LDH isoemzymas.

Objective To establish gas chromatography for determining the contents of borneol in aqueous humor and perfusate of rabbit cornea.Methods Naphthalene was used as the internal standard,samples were extracted by ethyl acetate and the chromatographic procedure was carried out in OV-1701 capillary column.The parameters were set as follows:Inject Temp,210 ℃;Oven Temp,30 ℃;FID Temp,250 ℃;Carrier gas:Nitrogen,3.0psi;Hydrogen,45 ml/min;Air,450 ml/min;split ratio,10:1.Results Borneol and isoborneol were well separated from other components.Borneol and isoborneol had an good linearity in the rang of 0.2～20 ?g/ml,R2 was 0.9953 for borneol and 0.9902 for isoborneol;and the intra-day and inter-day RSD were less than 9.68 %and 12.60 %respectively.Conclusion The method is simple and precise,and can be used for determining borneol in ophthalmological preparation.

Objective To observe the effect of Zhipu Hollow Suppository (ZHS) on postoperative ankylenteron in rats,and to investigate the possible mechanism.Methods Forty Wistar rats were randomly divided into model group,ZPS group,positive control group,and blank control group,10 rats in each group.Rats were given corresponding drugs according to the experimental design after modeling.Rats were executed after medication for one week,and the pathologic changes of ileal serosa were observed under scanning electron microscope and the ultrastructure of ileal serosa cells was observed under transmission electron microscope.Results Results of the examination under scanning electron microscope showed that the arrangement of ileal-serosa mesothelial cells in ZHS group was regular,and the network structure arranged spindle-shaped with uniformity size and with the shape close to the normal ones.There was proliferation in mesothelial cells in the exposed base layer.Under the transmission electron microscope,mesothelial cells recovered well and the proliferation of fibroblasts was not obviously in ZHS group,but mesothelial cells disappeared and the secretion of collagen by fibroblasts was actively in the model group.Conclusion ZHS can prevent ankylenteron by promoting the ileal-serosa mesothelial cell proliferation,improving the ileal-serosa ultrastructure and protecting the ileal serosa.
