  • To examine the effects of pomegranate on cerebral blood flow and obesity, we observed regional cerebral blood flow in normal rats, as well as body weight, serum total cholesterol, serum HDL-cholesterol, serum LDL-cholesterol, serum triglycerides, serum total lipids, serum phospholipids and serum free fatty acid levels in rats fed a high fat diet. The results were as follows. Pomegranate seed extract significantly increased regional cerebral blood flow and the peel extract increased regional the cerebral blood flow in a dose dependent manner. In addition, the pomegranate extracts(seed, peel, juice) decreased body weight, serum total cholesterol, serum LDL-cholesterol, serum triglycerides, serum total lipids, serum phospholipids and serum free fatty acid levels, and increased serum HDL-cholesterol in the rats fed a high fat diet. More specially the seed extract significantly decreased serum total cholesterol, serum triglycerides and serum phospholipid levels.

  • Magnesium(Mg) plays an important role in lipid metabolism and Mg deficiency but Ca sufficiency Increases serum cholesterol and triglyceride. The relationships of serum Mg, Ca, Ca/Mg ratio with lipids was examined in 79 female college students in Choong-Nam area. Subjects were divided into underweight, normal and overweight groups according to their BMI. The average age, body weight, height and BMI were 21.9yr, 55.9kg, 158.5cm and 22.62kg/$m^2$ respectively. Height was not different between groups. Serum cholesterol and LDL-cholesterol concentrations were significantly lower in the underweight group than other groups. BMI had positive correlations with LDL-cholesterol, atherogenic index (AI) and LDL-cholesterol/HDL-cholesterol ratio(LPH), and negative correlations with HDL-cholesterol/total cholesterol ratio. Serum minerals (serum Mg, Ca, Ca/Mg ratio) and serum lipid concentrations were not significantly different between groups. However, there was a tendency of increasing serum Mg level with increasing serum HDL-cholestrol, HDL-cholesterol/total cholesterol ratio and decreasing serum LDL-cholesterol, LPH, total cholesterol/HDL-cholesterol ratio(TPH) and AI. And there was a tendency of increasing serum Ca level with increasing serum HDL-cholesterol/total cholesterol ratio and decreasing serum triglyceride, LDL-cholesterol, LPH, TPH and AI. And there was a tendency of increasing serum Ca /Mg ratio level with decreasing triglyceride, serum LDL-cholesterol and TPH. This study was limited within serum levels of minerals (serum Mg, Ca and Ca/Mg ratio), serum lipids concerned with CHD, therefore I hope there will be wider efforts to consider about the dietary levels of minerals for presentation of the connection between dietary Mg, Ca and serum lipids.

  • This study has been done with 1,431 subjects who visited Health Promotion Centers of the hospitals in Gumi for National Health Screening Program for People at Transitional Ages from April to December 2007. Serum biochemical tests related with metabolic syndrome were performed. Among biochemical factors related with metabolic syndrome, the mean values of serum glucose, AST, ALT, triglyceride and HDL cholesterol except LDL cholesterol were significantly higher in males than in females, so a significant difference by sex was observed (P<0.001). AST, ALT, triglyceride and HDL were thought to be significantly affecting serum GGT for males. In contrast, ALT and HDL cholesterol were important factors for females (P<0.001). For both sexes, serum glucose and LDL cholesterol did not produce any meaningful effect on serum GGT. In males AST, ALT and HDL cholesterol were associated with high risk of abnormality of serum GGT and in females AST, ALT and LDL cholesterol were related with high risk of abnormality of serum GGT. Therefore, AST and ALT showed a significant effect on abnormality of serum GGT in both males and females. It was observed that males exhibited significantly high correlation between metabolic syndrome related biochemical factors and serum GGT than females, and their influence on abnormality of serum GGT was also higher in males than in females. Therefore, serum GGT tests performed for health screening are considered to be useful for managements of cardiovascular diseases and metabolic syndrome as well as liver function test.

  • Attenuated varicella-zoster virus(VZV) was cultured in human embryonic lung cells. The effects of serum type and its concentration on the production of VZV were studied. Regardless of cell culture conditions, VZV yield was increased with multiplicity of infection, and the total cell concentration was decreased after virus infection. The newborn calf serum, calf serum, or horse serum was not as good as the fetal bovine serum or calf serum supplemented with iron for the propagation of VZV in the human embryonic lung cells. The yields of total VZV(cell-associated virus and cell-free virus) in the medium with calf serum containing iron were comparable to those in the medium supplemented with fetal bovine serum. Furthermore, some components of serum appear to be important for the maintenance of VZV infectivity.

  • This study was designed to determine serum osmolality and to investigate the association among serum osmolality, health-related factors and biochemical indices. Two hundred thirty seven elderly(86 male, 151 female : mean age 73.8) residing in the chungbuk area participated. Sociodemographic data and self-perceived health status were obtained by interview, and biochemical parameters were measured. The mean serum osmolaity was 301.2$\pm$10.1 mOsm/kg(range 240.8~328.9 mOsm/kg) and serum osmolality of the females(302.4 mOsm/kg) was significantly(p<0.05) higher than that of the males(299.0 mOsm/kg). Only 11.0% of the elderly were within the accepted normal range(280~295 mOsm/kg) and the majority of the subjects were in a hyperosmolar state(60.8% : 296~307 mOsm/kg). It was observed that serum osmolality was reduced with increasing age but not statistically significant. There was no significant difference in serum osmolality according to marital status. Serum osmolality was significantly lower(p<0.05) in the elderly with higher self-perceived health scores than the elderly with lower self-perceived health scores, however no significant difference was observed between the presence or absence of disease. Serum osmolality tended to be higher(p=0.06) in the elderly with difficulty in mobility than the elderly who have no problem in mobility. Serum osmolality tended to be higher(p=0.06) among drug users compared to that of non-users. There was a significant association between serum osmolality and serum albumin in females but not in males. Significant associations were shown between serum osmolality and serum transferrin in both sexes. However, there was no significant correlation between serum osmolality and hemoglobin or hematocrit except with hematocrit in females only. The results of this study indicated that the elderly were dehydrated and hydration state seems to influence health status and, the elderly should be encouraged to drink an adequate amount of fluids. Also, the hydration state is required to be assessed and considered for the interpretation of biochemical parameters.

  • The purpose of this study was to measure serum lipids concentrations by gender and age, and to investigated the relation of serum lipids levels to cigarette smoking alcohol intake exercise and menopausal status in Korean adults. The subjects consisted of 463 healthy adult(29- men and 173 women) volunteers who were visiting the health Promotion Center in the Asan Medical Center from July 1, 1994 to July 22, 1994 Subjects were ambulatory free-living people and aged 20- 80 years, Anthropometric measurement was performed and serum triglyceride(TG), HDL-cholesterol and total cholesterol(TChol) concentrations were measure by automatic system(Hitachi 736-40). Data on life styles were obtained using structured questionnaires issued by a trained interviewer, All data were statistically analyzed by PC-SAS(Version 6.04) Serum concentrations of triglyceride and total cholesterol was higher(p<0.05) in men than in women, and serum HDL-cholesterol was lower(p<0.05) in men than in women. The prevalence of hyperlipidemia(TG>170 mg/dL and TChol>220 mg /dL) was 12.5% in men and 4.1% in women. The levels of serum triglyceride, total cholesterol and BMI increased with age in women. The distribution curves of serum triglyceride, total cholesterol and LDL-cholesterol of women were located in lower increased more rapidly with aging than in men, The distribution curves of BMI of women increased with aging after the thirties, The BMI of women was located in higher levels than of men in their sixties. The serum concentration of triglyceride and total cholesterol of male current-smokers and non- smokers were significantly(p<0.05) higher than those of ex-smokers. The concentrations triglyceride the male current0drinkers were higher(p<0.05) than those of male non-drinkers. In non-smokers and non- drinkers, serum TG concentration were lower (p<0.05) than those of current-smokers and current-drinkers. In exercisers, the serum triglyceride concentration was significantly(p<0.05) lower than in non- exercisers. In postmenopausal woman BMI and serum concentrations of TChol, TG and LDL-Chol were significantly by age and gender and smoking alcohol drinking, exercise and menopausal staus might be a better indicator to predict serum lipids in both genders.

  • The present study was performed to investigate the effects of caffeine and heparin on capacitation and acrosome reaction of bovine spermatozoa, effects of antisperm antibodies on acrosome reaction of bovine spermatozoa. The rates of acrosome reaction in control group, caffeine treated group, heparin treated group, caffeine-heparin complex treated group were 40.3, 54.3, 63.3, 72.3%, respectively and there were significant differences among the groups(p<0.01), especially higher in caffeine-heparin complex treated group than the others. The rates of acrosome reaction of antisperm antibodies serum supplemented groups(5, 10 and 20%) were 60.4, 48.9 and 37.1%, respectively and there were significant differences among the groups(p<0.0l), and the more increases in serum concentrations, the more decreases in acrosome reaction, but this phenomenon was not seen in fetal calf serum supplemented group and heifer serum group. When the serum concentration was 5%, the rates of acrosome reactions were significantly lower in fetal calf serum supplemented group than heifer serum group and in antisperm antibodies serum group(p<0.01), and there were no significant differences between heifer serum group and antisperm antibodies serum group(p<0.01). When the serum conecntrations were 10%, 20%, the rates of acrosome reactions were significantly lower in antisperm antibodies serum supplemented group than in fetal calf serum group and in geifer serum group(p<0.01), and there were no significant differences between fetal calf serum group and heifer serum group(p<0.01). These results indicate that caffeine-heparin complex treatment is very effective for inducing acrosome reaction of bovine spermatozoa and that antisperm antibodies block acrosome reaction.

  • Chrominum (cr) plays an important role in carbohydrate and lipid metabolism , and Cr deficiency impairs glucose tolerance and increases serum cholestero and triglyceride. The relationship of serum Cr with serum blucose and lipids was examined in 79 female college students in Choong-Nam areas. Subjects were divided into underweight , normal , and overweight groups according to their BMI. The average age, wiegth , height and BMI were 21.9yr, 55.9kg, 158.5cm and 22.6kg/$m^2$, respectively. Heights were not different between groups. Serum Cr and glucose concentrations werenot significantly different between groups. However, there was a tendency toward lowered serum Cr levels in under and over-weight groups. Serum cholesterol and LDL-cholesterol concentrations were significant lower in the underweight group than in other groups. BMI had positive correlation with LDL-cholesterol , AI and LPH , and negative corelations with HDL -cholesterol /total cholesterol ratio. Low serum Cr concentration was related to increased LDL-cholesterol and total cholesterol, and related to decreased HDL cholesterol in all groups . Therfore, serum Cr levels were lowered in abnormal weight groups and Cr may playan important role in coronrary heart diesease.

  • In an attempt to evaluate the diagnostic significance of the serum thyroid hormones in various thyroid function states, the author measured serum $T_3$ uptake, serum $T_3$, serum $T_4$, serum free $T_4$ and free $T_3$ index in 27 cases of normal subjects, 11 cases of hypothyroidism, 152 cases of euthyroidism and 81 cases of hyperthyroidism by the radioimmunoassay method. The results were as follows: 1. The ranges of serum thyroid hormones in normal subjects were, serum $T_3$ uptake; $27.4{\sim}42.1%$, serum $T_3;\;93{\sim}245ng/dl$, serum $T_4;\;4.08{\sim}12.9ug/dl$ and serum free $T_4;\;0.57{\sim}1.53ng/dl(M{\pm}2S.D.)$. 2. Free $T_4$ index and serum $T_4$ show relatively high diagnostic value in euthyroidism group, and serum $T_3\;and\;T_4$ in hypothyroidism group, while serum $T_3$, free $T_4\;and\;T_4$ show relatively high diagnostic value in hyperthyroidism group. 3. There were significant correlation between free $T_4$ index and serum $T_4$(r=0.68), and between free $T_4$ index and serum free $T_4$(r=0.67) in hyperthyroidism group.

  • Atopic dermatitis (AD) has become a serious epidemic in Korean children. We aimed to investigate the association between vitamin C, E and other nutrients, and serum total IgE/specific IgE levels in children with AD. A total of 119 children (0-24 mo) diagnosed with AD were recruited for this cross-sectional study from a medical center in Seoul. A 24 h recall was used to assess dietary intakes. Serum total and six food-allergen specific IgE levels were measured by CAP-FEIA. Serum vitamin E was also measured but only in 25 out of the total 119 participants. Multiple linear regression analysis was performed to estimate the coefficients between serum IgE levels and dietary intake as well as serum vitamin E. Serum vitamin E levels showed a significantly inverse association with serum total IgE and all specific IgE levels (P < 0.05). Fat intake was inversely related with specific-IgEs for egg whites, milk, buck wheat, soy, and peanuts (P < 0.05). Positive associations were found between carbohydrate (CHO) intake and total IgE and specific IgEs to egg whites, milk, soy, and peanuts (P < 0.05). Vitamin C, E and n-3/n-6 fatty acids were not related with serum total IgE and specific IgE levels except for the association between buck wheat and vitamin E. In addition, there were no significant differences between males and females in dietary intake and serum IgE levels by student's t-test. Although dietary vitamin E showed no association with serum IgE levels, serum vitamin E drew a significant inverse relationship with serum IgE levels. The evidence seems to suggest that vitamin E may possibly lower total and specific-IgEs in children with AD, and that it is important to maintain a relatively high serum vitamin E level in children with AD.
