Analyses of lead and zinc were made by means of standard addition method using atomic absorption spectrophotometer(Baird Ltd., Model A5100) with flameless method for lead and flame method for zinc. The blood samples used were merely diluted with triton x-100, because it was simple, rapid and minimal risk of contamination. Mean recovery rate for lead added to the blood ranged from 97.7 to 101.3% with coefficient of variation ranging from 1.9 to 10.7%, and that for the added zinc ranged from 99.0 to 102.2% with coefficient of variation ranging from 2.1 to 9.1%. In repeated measurements of zinc in the blood, good reproducibility and inter-individual variation were proved(p<0.01). In comparison of the lead and zinc concentrations in the blood determined by the standard addition method and standard method, there were good correlations between 2 sets of data (r=0.9731 for lead and r=0.9785 for zinc), although lead levels were estimated higher by the former method(p<0.01) and zinc levels by the latter method(p<0.01). It can be concluded that lead zinc levels in blood standard addition method is reliable for determination of lead and zinc in the blood with good accuracy and reproducibility.

We have performed assay for zinc on the expressed prostatic secretion in 52 consecutative patients with complaints of chronic prostatitis along with 23 controls. Among 52 patients, 29 are chronic bacterial prostatitis and 23 are chronic non-bacterial prostatitis. The result is as follows: 1. There is a significant difference(p<0.01) of the concentration of zinc in expressed prostatic secretion between the patient and the control. 2. Not remarkable difference of the concentration of zinc between the bacterial prostatitis and the non-bacterial prostatitis is elucidated.

This study was carried out to evaluate the relationship between the biological lead exposure indices and air lead concentrations measured by personal air samplers. The 72 occupationally lead exposed workers were observed and the biological lead exposure indices chosen for this study were blood lead(PuB), urine lead(PbU), zinc protoporphyrin in whole blood(ZPP), gamma-aminolevulinic acid in urine(ALAU), gamma-aminolevulinic acid dehydratase activity(ALAD), coproporphyrin in urine(CPU) and hemoglobin(Hb). The workers were divided into four groups by air lead concentrations: Group I; under 0.05 mg/m3, Group II; 0.05-0.10 mg/m3, Group III; 0.10-0.15 mg/m3 and Group IV; and over 0.15 mg/m3. For evaluation the relationship between the biological lead exposure indices and air lead concentrations was used as correlation coefficients. The results obtained were as follows: 1. In Group I, II, III and IV, the mean value of PbB were 25.45+/-1.84 microgram/dl, 27.87+/-3.53 microgram/dl, 31.21+/-1.76 microgram/dl and 47.02+/-13.96 microgram/dl. Between Group IV and other groups showed statistically significant difference(p<0.05). 2. There was an increasing tendency of PbB, PbU, ALAU and ZPP according to the increase the mean air lead concentration, while ALAD has decreasing tendency. CPU and Hb did not show any constant tendency. 3. Correlation coefficients between PbB, PbU, ZPP, ALAU, ALAD, CPU, Hb and air lead concentration were 0.95, 0.83, 0.89, 0.72, -0.83, 0.51 and -0.45 respectively, and regression coefficient between PbB(Y) and PbA(X) was Y=126.8746X+16.9996(P<0.01).

To study the preventive effects of zinc supplementation on malnutrition during the first months of life (5-7 months of age) in healthy Vietnamese children. Infants were divided into 2 groups: one received for 6 months a syrup containing 10mg of zinc, other group received a placebo. The results showed that, zinc level in all groups were higher than in placebo group. Zinc administration increased the growth velocity of weight and height compared with placebo, particularly in female. Growth factor-I (IGF-I) levels decreased from 26ng/mL to 25ng/mL for both groups, but increased by 10% in the zinc treated females.

A randomized, double blind study on 968 infants aged 5-7 months in Que Vo district, Bac Ninh province was carried out for 6 months. The infants were randomly received one of four following syrups: zinc sulfate, iron sulfate, combined zinc and iron sulfate or placebo. By the end of the study, weight, WAZ and WHZ values and their changes over the study period were significantly different between zinc supplemented group and the remaining ones, the change of height was significantly different between zinc supplemented group and iron supplemented and placebo ones only, hemoglobin and serum zinc value was increased in all groups. Hemoglobin value and its changes were significantly increased in iron and iron+zinc supplemented groups in comparison with the remaining groups.
