AIM: To study the effect of copper transporting P-type ATPase in copper metabolism of hepatocyte and pathogenesis of Wilson disease (WD). METHODS: WD copper transporting properties in some organelles of the cultured hepatocytes were studied from WD patients and normal *** cultured hepatocytes were incubated in the media of copper 1. mg x L(-1. only, copper 1. mg x L(-1. with vincristine (agonist of P-type ATPase) 0.5mg x L(-1., or copper 1. mg x L(-1. with vana{1.te (antagonist of P-type ATPase) 1..39 mg x L(-1. separately. Microsome (endoplasmic reticulum and Golgi apparatus), lysosome, mitochondria, and cytosol were isolated by differential centrifugation. Copper contents in these organelles were measured with atomic absorption spectrophotometer, and the influence in copper transportion of these organelles by vana{1.te and vincristine were comparatively analyzed between WD patients and controls. WD copper transporting P-type ATPase was detected by SDS-PAGE in conjunction with Western blot in liver samples of WD patients and controls. RESULTS: The specific WD proteins (M(r)1.5,000 lanes) were expressed in human hepatocytes, including the control and WD patients. After incubation with medium containing copper for 2 h or 24 h, the microsome copper concentration in WD patients was obviously lower than that of controls, and the addition of vana{1.te or vincristine would change the copper transporting of microsomes obviously. When incubated with vincristine, levels of copper in microsome were significantly increased, while incubated with vana{1.te, the copper concentrations in microsome were obviously decreased. The results indicated that there were WD proteins, the copper transportion P-type ATPase in the microsome of hepatocytes. WD patients possessed abnormal copper transporting function of WD protein in the microsome, and the agonist might correct the defect of copper transportion by promoting the activity of copper transportion P-type ATPase. CONCLUSION: Cop

Natural Disaster Reduction in china 2003年第4期 32-37页

作者： Zhou Youyou\+1.and tang Xiaochun\+2 (1.School of Resources and Environment, Guangxi {1. College, Nanning 530001. Guangxi 2. Geography department, south china normal university, guangzhou 51.61., Guangdong)

The subtropical \%karst\% mountain area is mainly distributed in southwest{1. and south{1.. Its landforms are mainly peak\|formed low\|lying lands and \%karst\% valleys that are formed by the intercalation of Cambrian system, Permian system, carbonate rocks, fragmentary rocks. Because the ecosystem is extremely vulnerable, and the interference from human activities is heavy, it is difficult for a long period to rationally exploit and utilize the resources in this area and the environment has been deteriorating increasingly. With the implementation of West{1. Development Strategy, such problems as the deterioration of the environment, the backwardness of the economy, and the irrational exploitation and use of resources have attracted the great attention of such academic circles as geography, \%karst\%, ecology and environment. The recovery and restoration of the ecosystem and the rational planning of agriculture, forestry and other industries have become tasks that demand immediate actions.

The influence of exercise at high temperature on adult males＇ routine blood indexes and biochemical indexes and the expression of HSP72 in peripheral blood lymphocytes （PBLs） was studied in order to provide theoretical ground for health supervision of adults receiving exercise at high temperature. 1.0 adult males were selected and divided into exercise group and control group, in which the exercise group was subdivided into subgroup 1.and subgroup 2 receiving exercise at high temperature in the afternoon and in the morning, respectively. Peripheral venous blood was phle- botomized before and after the exercise to examine routine blood indexes and blood biochemical indexes. The expression levels of HSP72 in PBLs were detected by flow cytometry. The results showed that the routine blood indexes and biochemical indexes in each group were within the range of normal values of male adults. There was no significant difference between each exercise group and control group in indexes before exercise. After exercise, the expression levels of HSP72 in PBLs in exercise groups were higher than those before exercise, and HSP72 expression levels in subgroup 1.were obviously higher than those in subgroup 2 and control group. The contents of ALT, urea, Na＋, Cl-, Ca2＋ and K＋ in subgroups 1.and 2 were lower than those in control group, but CK level was higher than in control group （P〈0.05）. The contents of Na＋ and Clin subgroup 1.were relatively lower than those in subgroup 2 （P〈0.05）. It was concluded that while receiving exercise at high temperature, adult males＇ HSP72 levels in PBLs could be increased and the biochemical indexes changed. Attention should be paid to health supervision to avoid obvious body injuries at high temperature.
