The effects of acute carbon monoxide poisoning on the hepatic blood flow were studied in mongrel dogs. In this study dogs were divided into two groups, namely control and experimental, and the hepatic blood flow measured by the determination of the fractional clearance of the intravenously administered colloid 198Au. In the experimental group carbon monoxide poisoning was induced by the rebreathing of about 2% CO gas mixture for 15 minutes, and the hepatic blood flow was measured before and 30 minutes after the completion of the rebreathing of the gas mixture. The hepatic blood flow in the experimental group showed a insignificant relative increase compared to that in the control group. The alteration of the mean value of the hepatic blood flow following carbon monoxide poisoning appeared proportionate to that of the cardiac index, and inversely proportionate to those of the femoral artery mean pressure and the total peripheral resistance. However, the individual value of hepatic blood flow revealed no correlation with any of these hemodynamic measurements.

The aim of this study was to assess the degree of association between individual stress and the amount of smoking among male senior students of a medical college. The questionnaire survey was conducted twice for collecting the data on stress level in terms of BEPSl score, smoking amounts, alcohol intake, and residence type in 1992 and 1993. Among the 223 responders, 39.9% were smokers. In the smokers, the association between stress level and smoking amount was significant after controlling for alcohol intake and residence type (P < 0.l). Especially in the group of living without family, the association was more significant (p=0.06). Therefore, it is recommendable that the stress management program is called upon for the student smokers to reduce smoking amount.

BACKGROUND: Osteoporosis results from bone loss due to menopause [estrogen(E) deficiency] and aging. Initial skeletal effect of menopause is accelerated bone resorption with an increase in seurm calcium(Ca) and compensatory but inadequate bone formation. Secretion of parathyroid hormone(PTH) is suppressed at this time. Postmenopausal osteoporosis results in fractures predominantly of trabecular bone, i.e., vertebra. With aging, secondary hyperparathyroidism by low serum Ca and vitamin D deficiency superim poses. Senile osteoporosis produces hip fractures, area of cortical bone. The aim of this study was to- examine the association of vitamin D[25(OH)D] and intact(i) PTH with bone mineral density(BMD) after controlling for suggested confounding factors, and the possibility of low serum vitamin D and high serum iPTH concentration could impact bone loss in Korean postmenopausal women. METHODS: Data from 188 postmenopausal Korean women aged 42 to 69 were analyzed through BMD, serum 25(OH)D, iPTH, Ca, phosphorus(P), alkaline phosphatase(ALP) and clinical characteristics. Factors affecting BMD was determined by Pearson correlation and the relationship between lumbar and femoral neck BMD and vitamin D[25(OH)D] and iPTH was assessed by multiple regression analysis after adjus- ting for suggested confounding factors. RESULTS: Lumbar and femoral neck BMD, serum Ca, P were decresaed and serum iPTH was increased with aging. In Pearson`s correlation, significant contributing factors to lumbar BMD was age, height, weight, menarche, year since menopause(YSM) and ALP. And significant contributing factors to femoral neck BMD was age, height, weight, menarche, YSM and iPTH. No relationship could be demonstrated between serum vitamin D[25(OH)D] and lumbar and femoral neck BMD. How ever, after controlling for potential confounding factors, a correlation was found between vitamin D[25(OH)D] and both of lumbar (p=0.013) and femoral neck BMD(p=0.077). iPTH was inversely related to femoral neck BMD(p=0.004) only in multiple linear regression. CONCLUSION: Serum vitamin D[25(OH)D] was influencing both of vertebral and femoral neck BMD, which suggests a significant role of vitamin D deficiency in the pathogenesis of postmenopausal osteo- porosis. In age related remodeling and loss of bone, increased serum iPTH might have additive role in cortical bone of femur. These findings suggest that vitamin D is very important for optimal bone health and a deleterious effect of increased iPTH on cortical bone loss. Adequate calcium and vitamin D status have to be maintained to prevent osteoporosis in postmenopausal Korean women.

The authors studied anxiety, using Zung's Self-Rating Anxiety Scale (SAS), in the subjects of 3,499 male and 1,335 female college freshmen of Yeungnam University. The authors collected the reports of SAS during the periods from January to February, 1986, and applied ANOVA and t-test on anxiety scores in order to compare them between various psychosocial factors, and sexes. The results are as follows: There was significant difference in the mean averages of total anxiety scores between male and female students: male students scored 32.91±7.70, female students scored 34.48±6.00, (P<0.001). The anxiety scores relating to the items of sweating, apprehension, restlessness, and insomnia were relatively higher in both groups. The anxiety scores relating to the items of faintness, mental disintegration, tremors, dizziness were lower in both groups. Thirty-nine male students (1.1%) showed seriously high anxiety scores of 50 or higher, while twenty-one female students (1.6%) showed the same scores. So the authors inferred that the features of anxiety symptoms were much the same in our country, but female showed more various symptoms and higher level of anxiety than males. Male students attending in pharmacy showed higher level of anxiety scores (P<0.01). There was a strong tendency toward higher anxiety scores in the students who were dissatisfied with their home atmosphere, colleges, department and familiarity of parents, and those who had pessimistic views of self image in the past, present, or future, in both groups (P<0.001).
