Abstract(1048)
Abstract:
On the basis o f epidemiolog ical sur vey on diabetes mellitus( DM) in jiangsu province, w e conducted a case control study to investigate the relationship bet ween smoking or drinking and diabetes.Newly diag nosed diabetes and impair ed glucose tolerance( TGT) patients were matched by their ow n contro ls respectively. Our result show ed smoking was related to DM. Those who smo ked more t han 26 cigarettes per dav were in hig her r isk of DM, the odds ratio of ever smokers was 5?? 60. T he morecig ar ettes an individual smoked in a day, the hig her risk he w ould take in DM. We hadn?? t found smo kingw as in r elation with IGT. Drinking habits, unlike smoking, w as proved not to be the r isk factor of DM or IGT acco rding to our study, but if consuming up to 35 kilogr ams pure alcohol per year, one would have a higher risk in IGT.

Abstract:
The serum copper, zinc iron, magnesium and protein levels of 50 patients with nephrotic syndrome, 28 pat ients with glomer ulonephritis determined by atomic absorption spectrophotometry.The serum copper, zinc, iron, magnesium and protein in glomer ulan diseases were analy zised. The results showed that the serum level of zinc in nephrotic syndrome group and glomerulonephr itis group was significantly lower than normal group. The serum levels of iron, magnesium were of insignificant difference between glomerulandiseases group and normal group. There were significant pos-itivecorr elations between serum zinc content and serum albumin content, and between serum zinc content and serum globulin content. The serum level of copper in nephrotic syndrome group was significantly lower than normal group. The serum level of copper were of insig nificant difference between glomerulonephritis group and no rmal group. There w er e significant posit ive cor relations between serum copper content and serum albumin content, and between serum copper content and serum globulin content. We suggest these changes are associated witht he gener at ion and state of disease.

Eff ects of Exposure to Low Concentration of Terephthalic Acid, Ethylene Glycal and Dowtherm A on Health of the Exposed Workers
Yao Hongwei
1999, 15(11): 1006-1007.
Abstract:
To study the effect of ex posure to low concent ration of terephthalic acid ( TPA), ethylene glycal ( EG) and dowtherm A( DOW) on health of the exposed workers, an occupational ep-idemiolo gicalinv estigation on 1230 ex posed workers and 177 controls in achemical fibr ecorpor ation was carried out. The results showed that the activity of ser um ALT, GGT, ALP and the ur-inary excretion of β2- 2-microglobulim (β2-MG) were significanlty higher in the exposed group than those in the controls( P<0.05 or P<0.01). The positiver ates of urinary protein and red blood cells in the exposed workers were higher too ( P<0.05 or P<0.01). It is suggested that the renal function and liver function should be impaired in TPA, EG, DOW chronically-exposed workers and that the combined effect of TPA, EG and DOW on the workers?? health should be probably considered. The comprehensive evaluation results comfirmed that the occupational hazard in this company showed atendency to improve.

Liu Dehua
1999, 15(11): 1025-1027.
Abstract:
The effcts folow-lead exposure on neurobehavior and hyperactivity in 360 inner-city school children were assessed by measuring he blood lead (PbB), air lead level and FEP、serotonin (5-HT)、dopamine (DA)、no radrenaline (NE)in whole blood.180 children living near abusy road are exposed to lead and 180 are as controls.All were given a neurobehavioral core test battery (WHO recommended neurobehavioral test battery, NCTB).Hyperactivity was quantified by using Co nner's teacher and parent's questio nnaire.As compared with the control group, the exposed group showed sig nificantly higher air-lead level 、blood-lead level、FEP and lower 5-HT level.The children with blood lead level≥10g/ dl were 59.17 %(66.67% in the ex posed group and 57.67% in the control group).Analy sis of the children's neurobehavio ral test performance showed the elevated lead levels (PbB ≥10μg/dl)were.associa ted w ith deficits in visualmo tor functioning 、visual-perceptual capacity and mood states.Hyperactivity was significantly increased with elevated bloo d lead lev els in the children.The children with PbB <10μg/ dl、FEP ≥ 50μg/ dl had deficit in visualmemory and attention.Thus, w e suggest the blood lead be 10μg/ dl as the definitio n of the children lead toxicity.THe children with PbB <10μg/ dl, FEP≥50μg/dl should also be prevented from lead to xicity.
