The present paper reports the effects of low and high doses of X-irradiation on hCG-induced testosterone secretion in cultured rat Leydig cells. The Leydig cells harvested from testis in immature rats were exposed to 25, 50, 75, 100, 250 mGy and 0.5, 1.0, 2.0, 4.0, 8.0 Gy X-irradiation at a dose-rate of 12.5 mGy/min and 0.51 Gy/min respectively after a preincubation for 24h. The cells were stimulated with 0.025 or 0.05 i.u./ml of hCG for 48 h in culture after X-irradiation. In low dose irradiated Leydig cells, the response to 0.05 i.u./ml of hCG in both 25 and 50 mGy groups was significantly higher than that of the control. No significant changes were found in response to 0.025 i.u./ml hCG in all the low dose groups. In high dose irradiated Leydig cells, the response to either 0,025 or 0.05 i.u./ml hCG was significantly inhibited in a dose-dependent manner. It is concluded that low dose ionizing irradiation acts synergistically with hCG in stimulation of testosterone production, while higher doses inhibit its secretion. The possible mechanisms of these effects were discussed.

The mechanism may be related with its protection of cell membrane and antioxygen.

Objective To confirm the effect of lymphangiogenesis in immunological reaction on pterygium formation and development.Methods The clinical removal of pterygium material in quiescent phase,advanced phase and recurrent phase was selected.each phase with 12 cases,while 10 cases of normal bulbar conjunctiva were taken as control.5'-nueleotide enzyme-alkallne phosphat&se-double enzyme histochemistry was performed to compare the number of lymphangiogenesis in different tissues.Results Lymphangiogenesis in normal bulbar conjunctiva and quiescent phase pterygium tissues expressed little,but gray-stained lymphangiogenesis widely distributed in pterygium tissue of advanced phase and recurrent phase,and there were statistically significant differences compare those with the normal bulbar conjunctiva and quiescent phase pterygium(P=0.03 and 0.01).Conclusion Lymphangiogenesis may be involved in immunity process of pterygium pathogenesis.

Objective To study the effect of CMPS on acute fatty liver induced by DL-E. Methods Oral administration DL-E (250 mg/kg) was given to mice to establish the models of acute fatty liver mice. Liver index, the contents of TG and morphological changes of liver tissue were detected to study the effect of CMPS on liver fat accumulation.Results The Liver index and the contents of TG in the model group rose. Under light microscope, lobular central vein could be seen around the liver steatosis and cytoplasm of liver cells appeared vacuolated changes. As compared with the model group, indexes significantly improved in CMPS group. Conclusion DL-E could obviously damage the liver and lead to liver fat accumulation. CMPS has protective effect on liver injury.

BACKGROUND:The phenomenon of temporary ischemia of the tissues and organs caused by injury is common in the clinic. However, there are few studies on the treatment of ischemia/reperfusion injury. It is significant to investigate the effect of TanshinoneⅡA on improving uterine ischemia/reperfusion injury in a rat model. OBJECTIVE:To observe the effect of TanshinoneⅡA intervention on improving uterine ischemia/reperfusion injury in rats. METHODS:The rat models of uterine ischemia/reperfusion injury were established by suture method. The rats that were intraperitonealy injected with Sodium Tanshinone IIA Silate injection (20 mg/kg) at 5, 3, 1 days and 30 minutes before the operation were included in the experimental group. Model and sham operation groups were established for comparison. RESULTS AND CONCLUSION:Spectrophotometry and immunohistochemical staining results showed that at 1 and 3 hours of ischemia/reperfusion, the malondialdehyde concentration and Bax protein expression in the injuried rat uterine tissue were significantly decreased (P < 0.05), superoxide dismutase (SOD) activity and Bcl-2 protein expression were significantly increased (P < 0.05) in the experimental group than in the model group. The results confirm that TanshinoneⅡA has a protective effect on uterine ischemia/reperfusion injury in rats.
