Objective To study the protective action of Shuganwan on liver injury and its cholagogue action. Methods Acute liver injury was induced by carbon tetrachloride in rats. The biochemical indexes and pathological changes were used for evaluation. The cholagogue action was studied by biliary drainage method. Results Compared with those of the CCl 4 control group, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and bilirubin levels of Shuganwan group declined significantly, and albumin/ globulin (A/G) inversion was obviously improved. The pathological changes revealed that liver injury was relieved. There was no change in bile secretion after administration of Shuganwan. Conclusion Shuganwan has protective action on acute liver injury by carbon tetrachloride, but no promotive action on bile secretion.

Objective To observe the protective effects of enalapril on the long-term functions of the allograft in renal transplant recipients. Methods Twenty renal transplant recipients with ~survival time over one year, normal renal functions of the allograft and urine TGF-?_1 levels being more than ~250.0 pg/mg.Cr took enalapril every day for at least one year. Twenty-three recipients under the same conditions who did not receive enalapril served as control group. Three years later renal ~dysfunction cases, loss of creatinine clearance rate (Ccr) and TGF-?_1 levels in blood and urine were compared between the two groups. The changes in the expression of TGF-?_1mRNA in renal biopsy specimens were compared before and one year after enalapril therapy. Side-effects of enalapril were ~investigated in all patients in enalapril-treated group. Results Three years later, the number of renal dysfunction cases was less, the loss of Ccr was less and the level of urine TGF-?_1 was lower in ~enalapril -reated group than those in control group with the differences being significant (P~0.05 ). One year after enalapril therapy TGF-?_1mRNA expression was significantly decreased in renal biopsy specimens (P

Objectives To understand the status of wild feces distribution and pollution in schistosomiasis endemic areas in Yunnan Province. Methods According to the distribution of Oncomelania hupensis snails and characteristics of human and ani-mal activities in recent five years 6 schistosomiasis endemic villages in Weishan Nanjian and Midu counties 2 villages each county were selected as the investigated areas and more than 4 hm2 area with snails around each village were investigated for the types and densities of wild feces. The schistosome infested feces was detected with the hatching method. Results Totally 63 hm2 were investigated and 420 wild feces were found in all kinds of environments. The densities of wild feces were 0.066 7 piles/100 m2 and the densities of wild feces of the road and the hillside were the highest 0.098 7 piles/100 m2 and 0.088 0 piles/100 m2 respectively . Totally 260 fresh wild feces were collected including the feces of human being cattle horse dog sheep and pig and the feces of cattle and dog was the most 37.38%and 30.71% respectively . No schistosome positive feces was found. Conclusions There are a lot of wild feces in snail areas in Yunnan Province and the risk of schistosomiasis transmission is still high. Therefore we should strengthen the banning grazing measures and the investigation of dogs.

Aim To investigate the effects of meloxi-cam on the proliferation,migration and expression of PTEN of human colorectal cancer LoVo cells.Meth-ods The colony formation test was used to detect the effect of meloxicam on the proliferation of LoVo cells. The cell migration assay was applied to analyze the effect of meloxicam on LoVo cells activity.The RT-PCR assay was used to detect the effect of meloxicam on the mRNA expression of PCNA and PTEN gene. The western blot assay was applied to analyze the effects of meloxicam on the expression of PTEN pro-tein.The recombinant adenovirus and Annexin-V assay were used to testify the relationship between PTEN gene and anti-cancer effect of meloxicam.Results Compared with the control group,meloxicam could in-hibit the colony formation and PCNA protein expression of LoVo cells.At 48 h and 80 μmol·L -1 ,the expres-sion of PCNA protein was reduced to 61 .57% ± 2.81 %(T =7.086,P =0.01 9),the mRNA expres-sion of PTEN gene increased to 1 60.43% ±4.71 %(T=24.244,P =0.002),and the expression of PTEN protein increased to 1 52.63% ±3.33%(T =27.359, P =0.001 ).Results Annexin-V test indicated that the anti-cancer effect of meloxicam was associated with the up-regulated expression of PTEN.Conclusions Meloxicam can inhibit the proliferation and migration of LoVo cells by up-regulating the expression of PTEN.

Objective To observe the efficacy of local gene transfection in CD154 extracellular domain on the survival of renal allografts. Methods The kidneys of Brown Norway (BN) rats were transfected with CD154 extracellular domain gene recombined adenovirus. The transfected kidneys were transplanted to Lewis rats (transfection group). BN→Lewis kidney transplantation with non transplanted kidneys served as the controls. The allograft survival time and the allograft function between the two groups were compared. Results The allograft survival time of the transfection group was longer than that of the controls significantly [(28?7.3)d vs (8.6?1.2) d, P

AIM: To study the action of Shugan Pills (SHGP) (Fructus Toosendan, Rhizoma corydalis, Radix Paloniae Albe, Radix Aucklandiae, Cortex Magnoliae Officinalis, Fructus Aurantii, etc.) on treatment of epigastralgia. METHODS: The analgesic effect was tested by the hot plate test and writhing method. The anti gastric ulcer action of SHGP was observed on the gastric ulcer induced by water immersion stress, reserpine and absolute ethyl alcohol. The effect on gastric secretion in rats was studied with pylorus ligation. The effect on gastrointestinal motility was observed by determination of gastric emptying and small intestinal propulsion ability in mouse. RESULTS: SHGP enhanced hot pain threhshold and decreased the number of twisting body in mouse. SHGP markedly inhibited gastric ulcer induced by water immersion stress, reserpine and absolute ethyl alcohol. SHGP significantly inhibited the secretion of gastric acid and pepsin and promoted the secretion of gastric mucus. SHGP markedly delayed gastric emptying in normal mouse and when gastric emptying and small intestinal propulsion was stimulated by neostigmine. SHGP faintly strengthed the effect of atropine on inhibition of gastrointestinal motility. CONCLUSION: Shugan Pills could have analgesic effect, anti gastric ulcer action, it inhibited the secrection of gastric juice and the activity of gastric smooth muscle. These effects might be the pharmacological mechanisms of SHGP on treatment of epigastralgia.

AIM:To investigate the effects of Zhouluotong (Radix Astragali, Ramulus Cinnamomi, Radix Angelicae Sinensis, Radix Rchmannia, Herba Asari, etc.) on nerve function and polyol pathway in streptozotocin diabetic rats. METHODS: Streptozotocin diabetic rats were administrated with Zhouluotong for 8 weeks. Effects of drugs on sciatic never morphological alterations, sciatic never conduction velocity, aldose reductase activity, Na +,K + ATPase activity and sciatic nerve polyol contents were determined. RESULTS: Compared with diabetic group, sciatic never morphological alterations was improved, sciatic never conduction velocity was increased, aldose reductase activity was depressed and Na +,K + ATPase activity was increased in each administrated group. Sorbitol and gloucose contents were decreased in Zhouluotong groups. CONCLUSION: Zhouluotong could improve metabolism and function of peripheral nerve issue in streptozotocin diabetic rats. As a result of that, it could prevent diabetic peripheral neuropathy in streptozotocin diabetic rats.
