Abstract:
Brain injury in Mongolian gerbil(Meriones unguiculatus) was induced by occluding bilateral common carotid arteries followed by reperfusion. Levels of ATP, ADP and HX in gerbil brain measured by HPLC method were decreased and increased significantly respectively after 60 min cerebral ischemia. The level of oxygen free radicals(OFR) measured by electron spin resonance(ESR)were increased significantly only at 5-min reperfusion. DTC, iv 50 mg·kg-115 min before occlusion, increased level of ATP and ADP in brain,reduced edema of neuron and tissue of brain and decreased the level of OFR in 5-min reperfusion group and the mortality of gerbil to 50% as dexame thasone did in the reperfusion group. The results suggested that DTC had protective effects on ischemia-reperfusion induced gerbil brain injury. The OFR in gerbil brain may be formated mainly by the route of xanthine oxidase.

Abstract:
This article reports activities of the Tosufloxacin in vitro and in vivo, toxicity, pharmacokinetics, clinical effects. Tosufloxacin has a broad spectrum against Gram-postive and-negative bacteria. It has potent antibacterial activities against Gram bacteria was Superior to Ciprofloxacin and Ofloxacin. It was well absorbed after oral administration. Clinic had excellent effect with various infections of patients and side was low.

Abstract:
The stability of SuanZaoRen pellet was studied with the method of constant temperature acceleration test according to the principle of chemial dynamics. It's content was determined and t0.925 was predictively determined to be 2.96a.

Abstract:
The rectal capsule of acetaminophene was prepared, it can be formed several sizes by children's weight so as to administrate in personal. Tmax, Cmax and AUC of the capsule and the suppository commercial were 1.87, 1.67h; 54.86, 46.69(μg/ml); 198.94, 188.94 (μg·h/ml) in rabbits respectively, the results showed that the suppository of acetaminophene can be substitued by the rectal capsule, it was a new dosage form in rectal administration, it's dissolution in vitro was determined by the method of rotating-cylinder with millipore memberane(RCMM) established by ourself. There are a significant correlation between the cumulative dissolution rates in vitro and the absorption rates in vivo, and the both meets zero-order kinetics, the results showed that RCMM could simulated the dissolution of rectal capsule in rectal, it provided a new method of determing dissolution of soluble suppositories, RCMM can simulated the conditions of poor liquid, pH≈7, temperature higher than body temperature but cann't simulated the larger absorption area and the pressure of rectal acting on preparations in rectal, it has several advantages such as simple operating, fixed diffusion area, regulating millipore memberane and non-ignoring the differances of preparations.

Abstract:
This paper reported a improved recipe and prescription technological process of Ftibamzonum Eye Drops(Ocustilla Ftibamzoni). The examinational results of 8 lots of products showed that the quality is stable and it stores well in 2 years at room temperature.

Abstract:
Compatible stability of injection Dexamethasone Sodium Phosphate and injection Vitamin B6 in 5% glucose injection were observed. The results showed that there were no significant changes in outward, pH and Rf in 6h after they had been mixed. Ultraviolet spectrophotometry was used to detect the content of Dexamethasone Sodium Phosphate. The results showed there were no significant changes. It has proved that the two drugs were compatible.

Abstract:
Five compounds(Ⅰ-Ⅴ) were isolated from Liaoxi propolis. Their chemical structures were established as multi-sulfur S8(Ⅰ),3,4-dimethoxylcinnamic acid(Ⅱ), isoferulic acid(Ⅲ), Caffeic acid(Ⅳ), and benzoic acid(Ⅴ) by spectra. Ⅰ and Ⅴ were found from the propolis for the first time.
