0.05).In2001the urinary? 2 -MG contents in cadmium-polluted area were also not significant different from that of the control area.Con clusion The present study indi cated that the renal disfunction had appeared in the part of women in cadmium-polluted area became of increased body burden of cad-mium induced by over-in taking cadmium from rice in1982and1987.However,the body burden of cadmium decreased and the renal function ameliorated and recovered gradually in women of cadmium polluted area following cessation of the intake of rice containing cadmium.

46 cases of recurrent oral ulcer were treated by acupuncture,after treatment CD +3 ,CD +4 ,and CD +4 /CD +8 ratio of T lymphocytes in peripheral blood of the patients were increased(P ＜0.05),CD +8 lymphocyte decreased(P ＜0.05).Acupuncture may improve cellular immune function of the patients with recurrent oral ulcer.

AIM To study whether chlorpromazine(CPZ) and verapamil (Ver) have protective effects on the nephrotoxicity of cadmium (Cd). METHODS Thirtytwo Wistar rats were divided randomly into four groups.Each agent was injected 5 times per week for 6 weeks.The rats in Cd-treated group were sc injected with CdCl2 7μmol·kg-1. The rats of CPZ- and Ver- pretreated group were ip injected with CPZ 5 mg· kg- 1, Ver 4 mg· kg- 1,respectively, 1 h later sc injected with CdCl2 7 μ mol·kg- 1. The control group was sc injected with saline 2 mL·kg-1 at corresponding time. Twenty-four hours after the last injection, the 24-h urine samples were collected. The renal cortex was also excised. Lactate dehydrogenase (LDH) activity, protein and Cd concentration in urine were determined.The activities of protein kinase C (PKC), Na + -K + -ATPase, Ca2 + -ATPase and Cd concentration of renal cortex were also measured. RESULTS Cd concentrations of renal cortex and urine in rats from Cd-treated group were significantly higher than those of control group.Cd concentrations in urine of rats from CPZ- and Ver-pretreated groups were significantly lower than those of Cd-treated group, but there was no significant change in renal cortex. As compared with control group, LDH activity, protein content in urine and the activities of PKC, Na+ -K+ -ATPase and Ca2+ -ATPase in the rats of Cd-treated group increased significantly. LDH activity, protein content in urine and activities of PKC,Na+ -K+ -ATPase and Ca2+ -ATPase in rats of CPZ- and Ver-pretreated groups were significantly lower than those of Cd-treated group. CONCLUSIONCd could activate the activities of PKC,Na+-K+-ATPase and Ca2+-ATPase. Moreover, pretreatment of CPZ and Ver could reduce nephrotoxicity of Cd.

BACKGROUND:Smoking is one of the major risk factors for the formation of atherosclerosis. OBJECTIVE:To investigate the effect of cigarette smoke extract on the concentration of GATA-2 in the vascular smooth muscle cells and in which the role of the early growth response factor-1. METHODS:Vascular smooth muscle cells were cultured in vitro. The vascular smooth muscle cells were treated with various concentrations of cigarette smoke extract (0, 5%, 10%, 20%), then the reverse transcription PCR was applied to detect the mRNA expression of GATA-2. The vascular smooth muscle cells were treated with cigarette smoke extracts in the optimal concentration for 0, 4, 8, 12 and 24 hours, and then the expression of GATA-2 mRNA was observed, as wel as the changes of expression of GATA-2 mRNA after added with growth response factor-1. RESULTS AND CONCLUSION:Compared to the 0 concentration group, the expression of GATA-2 mRNA after treated with low concentration (5%) of cigarette smoke extract was increased more significantly than moderate concentration (10%) and high concentration (20%). The vascular smooth muscle cells in 0 hour group expressed GATA-2 mRNA at low level. The GATA-2 mRNA began to increase within 4 hours and reached peak at the 8 hours after stimulated with cigarette smoke extract of 5%concentration. After added with growth response factor-1 inhibitors, the expression of GATA-2 mRNA in 5%cigarette smoke extract induced vascular smooth muscle cells was decreased. Cigarette smoke extract can promote the increasing of GATA-2 by growth response factor-1, while the GATA-2 expression is reduced after the inhibition of growth response factor-1.

Objective To evaluate the variability of four parameters of multi-focal electroretinogram (mERG) a-wave amplitude, b-wave amplitude, a-wave latent period, b-wave latent period. Methods Sixty normal eyes of 46 volunteers were divided into 3 groups of different ages. RETIscan 3 12 system was used to carry out mERG examination. The stimulus matrix of 61 hexagonal elements spanning the central 24?of the visual field. These hexons were scaled with eccentricity and divided into 5 rings. First-order kernel was selected. Results The variability of four parameters of mERG was great. The variability of b-wave latent period was the smallest, its coefficient of variatian was 4.52%～15.62%;that of a-wave latent period held the second place:10.29%~48.67%;that of b-wave amplitude was greater:25.92%~76.11%;that of a-wave amplitude was the greatest:43.82%~88.23%. The results of three groups showed that b-wave amplitude of ring 1 had the smallest variability. Conclusions The variability of latent period is smaller than that of amplitude; the variability of b-wave was smaller than that of a-wave. The longer the centrifugal distance, the lower the amplitude density of a-wave and b-wave. Physiological and anatomical factors might be important for the variability of parameters of multi-focal electroretinogram.
