To assess the pattern of psychiatric symptoms and to evaluate the relationship between exposure related variables(duration of work and urinary hippuric acid concenturation) and psychiatric symptoms in organic solvent exposed workers, case control study of forty-two solvent exposed workers and ninety-six non-exposed workers was conducted. The general health questionnaire 28(GHQ28) was administered to evaluate psychiatric symptoms and urinary hippuric acid concenturations was measured to estimate the present status of solvent exposure in exposed group and to estimate normal level in non-exposed group. The meand concenturation of urinary hippuric acid was significantly higher in exposed group (2.953g/creatinine g) than non-exposed group (0.395g/creatinine g) (P<0.01). The total positive rates of symptoms were significantly higher in exposed group(28.2%) than non-exposed group(17.5%) (P<0.05). The positive rates of symptoms for four sub-scales of GHQ 28 in exposed group were in the order of somatic symptoms, anxiety, social dysfunction, depression and in the order of social dysfunction, anxiety, depression, somatic symptoms in non-exposed group.The positive rates of symptoms for somatic symptoms and anxiety were significantly higher in exposed group than non-exposed group (P<0.05) and the proportion of workers with six or more positive symptoms(dysthymic states) in exposed group were significantly higher than non-exposed group (P<0.01). After the effect of age, sex, level of income, level of education, and duration of work were controlled, the total score of GHQ28 was still significantly different between exposed and non-exposed group(P<0.01). In multiple logistic regression analysis on the dysthymic state, the odds ratio of level of income was statistically significant in both group. The odds ratios of exposure related variables such as duration of work and hippuric acid concenturations were not statistically significant but there was a tendency that exposure related variables had an effect on dysthymic state in exposed group.In future, comtinuous evaluation of psychiatric symptoms on organic solvent exposed workers and studies to detect the factors that affect on psychiatric symptoms are required.

Image-guided localized, water-suppressed in vivo 1H MR spectroscopic studies were performed on the brain tumors in 3 patients. In all 3 patients, in vivo 1H MR spectra in brain neoplastic tissues revealed that the signal intensities of N-acetylaspartate (NAA) choline (Cho) resonances were decreased and increased, respectively, comparing with healthy normal tissue. A distinct lactate signal was identified in all three patients. A ratio that the observed metabolite alterations from localized, water-suppressed in vivo 1H MR spectroscopy can be useful as an index of brain tumors, and that the technique is clinically to highlight as one promising modalities in brain tumors for more accurate diagnosis.

Various renal functions were studied in 45 young Koreans, 41 males and 4 females. The glomerular filtration rate, the renal plasma and blood flows and the filtration fraction were comparable to those in the occidental. The renal diluting capacity, as judged by the value of positive free water clearance (CH2O), was also comparable to that in the occidental. However, the renal concentrating ability, as judged by values of both the maximum urine osmolality induced by pitressin injection or during dehydration and the maximum negative free water clearance (TcmH2O) during mannitol diuresis, was somewhat low in the Korean. The tubular reabsorptive capacity of glucose (TmG) Was significantly low in the Korean while the tubular secretory capacity of PAH (TmPAH) was not altered. The urea clearance and its ratio with the inulin clearance were generally low. Moreover, the normal osmolar composition of urine indicated that urea is responsible for only 20 to 30%, while salt accounts for nearly 2/3 of the total urine osmolality. In view of the fact that the Korean is chronically maintained on a low or poor protein diet, these results are discussed in the light of this peculiar dietary habit of the Korean. Although the reduction of both the renal concentrating ability and the urea clearance could be reasonably attributed to a low protein intake, the observed low value of Tmc could not be explained thus at present.
