Public protective actions against nuclear power plant accident / 中国辐射卫生

With the continuous development of nuclear energy, more and more people live around nuclear power plants. However, they generally lack basic knowledge of nuclear radiation and know little about protective actions against nuclear accidents. Timely and correct protective actions can minimize the harm of nuclear power plant accidents to public health. This paper introduces the public protective actions after the nuclear power plant accident: sheltering, decontamination of body surface contamination, evacuation, stable iodine prophylaxis, food and drinking water control, personal protective measures, pet care and psychological support, to guide the public to carry out protection actions correctly and improve the public's emergency response ability during the nuclear power plant accident.

Studies of the Protective Effect of Oral Yihuang Liquor on Immune Liver Injury in Mice / 中国药房

OBJECTIVE:To study the protective effect of oral Yihuang liquor on the immune liver injury of mice METHODS:The mouse models were established by injecting BCG+LPS qd through caudal veins on 10 successive days,then Yihuang liquor was given to mice through gastric tube The serum ALT,AST and weight of liver and spleen were determined,and the pathological changes of the liver were observed under light microscope before and after administration of Yihuang liquor RESULTS:Yihuang liquor in a large dose or middle dose could markedly decrease the levels of serum ALT and AST,lessen the swelling of liver and spleen,reduce the degeneration and necrosis of hepatic cells and inflammatory cell infiltration in portal area in mice with liver damage On one hand Yihuang liquor in a low dose could inhibit the immunofunction and alleviate delayed hypersensitive reaction in mice with normal or enhanced cellular immunofunction but on the other it could raise immunofunction and enhance the delayed hypersensitive reaction in mice with hypoimmunofunction CONCLUSION:Yihuang liquor can regulate cellular immunofunction and obviously protect the immune liver injury

Experimental Study of Cerebral Protective Action with Dexamethasone in a Rat`s Forebrain Ischemic Model / 대한마취과학회지

This study examined the protective effect of dexamethansone following bilateral forebrain ischemia in a rat model of two-vessel occlusion. Twenty rats were subjected to dexamethasone (1 mg/kg intravenously) before bilateral common carotid artery occlusion for 10 minutes. Carotid artery blood flow was restored and the rats were terminated by a perfusion-fixation method after 7 days. Ten minutes of two-vessel occlusion produced cellular ischemic change in the cerebral hemispheres of most rats. This region was studied mainly with light microscope, and it was noticed that the CA 1 neuron in the hippocampus is the most vulnerable to ischemia. Ischemic neuronal damage was graded in accordance with conventional neuropathological criteria. The grade had no statistical significance.

Protective action of Shuganwan on acute liver injury and its effect on bile secretion in rats / 西安交通大学学报(医学版)

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.
