This study was conducted to investigate the relationships among body composition, dietary intake, and clinical blood indices in college students by body mass index (BMI). Their body compositions were determined by means of BIA (Bioelectrical Impedance Analysis) method. Their dietary intake was determined using a 3-day record method and their hematological indices were determined by semi-automated microcell counter (Sysmex F-520). Their serum lipid levels were measured using biochemical analyzer (Spotchem). Subjects were classified as underweight, normal or over-weight groups according to their BMI. The subjects were 69 healthy college students aged 20 to 26 years. The average age, height, weight, and BMI was 21.3 years, 162.6 cm, 54.4 kg, and $20.6cm/m^2$, respectively. Their average consumption of energy was 1693 kcal, 84.7% of RDA and their mean ratio of carbohydrate: protein: fat were 54.5 : 16.4 : 29.0. There was no significant difference in nutrient intake among the groups except ${\beta}$-carotene and vitamin C. The ${\beta}$-carotene intake was significantly higher in the underweight group. Vitamin C intake was significantly higher in the overweight group. The mean intakes of Ca, Fe, Zn and folate of subjects were 74.8% to 83.2% of RDA. Especially, intakes of Ca, Fe, Zn and folate were lower in the abnormal weight groups. The overall mean values of the hematological indices in female college students were within the normal range and there was no significant difference among the groups. However, anemic subjects with hemoglobin (< 12 g/dl) and hematocrit (< 36 g/dl) accounted for about 11% of the subjects. The everall mean values of the serum lipid levels were within the normal range and there was no significant difference among the groups. But serum HDL-cholesterol level of the overweight group was lower than that of the other groups. LDL-/HDL-cholesterol ratio and AI index were significantly higher in the overweight group compared to the other groups. Based upon this study, it is necessary for college women to be educated regarding consuming more Ca, Fe, Zn, folate and less fat and cholesterol in order to have better health promotion.

This study is designed as pilot study to report the efficacy and safety of long term medication of Oncheongeum-gamibang on atopic dermatitis. The patient of atopic dermatitis was asked to take Oncheongeum-gamibang for 3 months. Every end of month, he had gotten hematological test and SCORAD Index examination. After the clinical trial was done, he had additional examination to see the changes and duration of medicinal effect. During the period of taking Onchung-um, estimation of symptoms by SCORAD Index examination showed little bit of improvement while taking medicine and after one month, the improvement was maintained. There were no significant changes in hematologic test and liver function test during and at the end of the clinical trial. We were able to find out that it is effective and safe to take long term medication of Oncheongeum-gamibang for an individual. However, due to deficiency of the cases and immunological values, there will be additional study to make up for better result.

본 연구는 의료기관에 종사하는 의료방사선 작업종사자에게서 직업적 방사선 피폭으로 인한 인체 내 생리적인 변화를 통해 만성적 저선량 방사선피폭의 위험도를 예측하며 현 수준의 변화 상태를 파악하기 위한 목적으로 서울시내 일개 대형병원에서 최근 1~9년간 방사선 작업종사자로 근무한 370명을 대상으로 남녀 간의 체내 혈액성분의 수치변화를 대조군과의 비교 분석을 실시하여 다음과 같은 결론을 얻었다. 1. 종사자의 1~9년간 평균 방사선 누적선량은 남자가 $9.65{\pm}15.2\;mSv$, 여자가 $4.89{\pm}5.55\;mSv$로 남자에서 높았으며 이는 통계적으로도 유의하였다(p<0.01). 2. 남녀 종사자 모두에서 누적선량과 종사기간의 차이에 따른 검사항목들과의 상관성은 매우 미약하였다(r<${\pm}0.25$) 3. 종사기간이 증가할수록 남자에서는 백혈구의 감소자와 증가자, 혈색소의 감소자, 당질의 증가자 비율 유의하게 높았으며(p<0.05), 여자에서도 백혈구의 감소 및 증가자, 호산구의 감소자의 비율이 유의하게 높았다(p<0.01). 4. 누적선량의 증가할수록 남녀모두에서 오히려 이상분포를 보이는 항목은 줄어들었으며, 남자는 림프구와 혈소판의 감소자가 유의하게 높았고(p<0.05) 여자는 림프구와 적혈구의 감소뿐만 아니라 종사기간에서 이상을 보였던 백혈구의 감소 및 증가자 역시 유의한 증가를 나타냈다(p<0.05). 5. 전체적인 변화를 보면 남자 종사자에서는 혈액성분 중 적혈구, 혈소판, 림프구가 주로 감소되며 백혈구는 감소와 증가양상을 같이 보였다. 화학성분 중 당질의 증가가 유의했지만 큰 의미는 없었다. 여자 종사군에서는 남자와 똑같게 백혈구가 감소, 증가 양상을 동시에 보였으며 그밖에 적혈구와 림프구, 호산구의 감소가 유의했다. 이상의 결과를 종합해보면 비록 낮은 선량에 피폭이 되고 있는 의료방사선 종사자일지라도 방사선 피폭에 있어서는 자유롭지 못하여 그 영향으로 인한 체내 생물학적 변화를 겪을 수 있으며 그 변화는 선량에 의존하기 보다는 다분히 확률적일 수 있다는 사실이다. 그러므로 항상 미연에 피폭을 방지하기 위한 노력을 종사자 스스로 기울임을 물론 관련 당국 또한 종사자들의 건강을 체계적으로 관리할 수 있는 시스템을 하루빨리 구축하여 방사선 피폭으로 인한 직업병의 발생의 우려를 없애야 할 것으로 사료된다.

This study was carried out to investigate the effect of body weight reduction of patty containing glucomannan in high fat diet-induced obese rats. Male Spraque-Dawley rats were randomly assigned to control and high fat diets groups for 4 weeks. After 4 weeks, the control and high fat diet groups were rearranged into 5 groups by different levels of patty containing glucomannan (60%). After 5 weeks, serum and whole blood levels were analyzed. Obesity index was significantly lower in the group fed patty containing glucomannan than that of high fat diet groups. The status of white blood cells in hematological examination was significantly higher in rats fed high fat diet and not significantly different from those fed patty. Serum albumin levels were not significantly different, while serum glucose levels were significantly different among groups. Serum Triglyceride and total cholesterol levels were the highest in rats fed high fat diets, while the lowest in rats fed patty containing glucomannan.

An experiment was conducted on crossbred male calves to study the effect of arsenic (As) on immunity status and certain hematological parameters. Ten crossbred male calves of 3-4 months of age were distributed into two equal groups. Group I was kept as control, whereas, group II was supplemented daily with 50 ppm As (as $As_sO_3$) up to 90 days, in the diet. Calves of both groups were fed as per ICAR standards and their requirements were fulfilled by feeding concentrate mixture and green oats. All calves were kept under similar managemental conditions. Blood samples were collected at fortnightly intervals to estimate various haematological parameters and superoxide dismutase (SOD) enzyme activity. Serum Ig and serum glutamic pyruvate transaminase (SGPT) were also measured. Cell-mediated immune responses of the calves were monitored at 0, 45 and 90 of experimental feeding, through lymphocyte proliferation. No change in blood total leukocyte counts (TLC), differential leukocyte counts (DLC), packed cell volume (PCV), haemoglobin (Hb) and SGPT was observed with As supplementation. A decrease in SOD activity was noticed in group II calves. Stimulation index (SI) for lymphocyte proliferation decreased from 1.14 to 0.79 in group II calves during 90 days experimental feeding, whereas, there was no change in SI values in group I indicating significant decrease in immune response of As supplemented calves. Blood As concentration increased in group II calves with the decrease in immune response. Short term supplementation of As to growing calves suggested suppressive effects on cell-mediated immunity. However, long term experiments are required to demonstrate clearly the efects of this toxic metal in calves.

This study was conducted to evaluate the effects of duck-meat consumption on adult disease risk factors, including body compositions, hematological variables, and serum metabolic and lipid profiles in adult human males. To obtain results, 20 adult males aged 20 to 25 were subjected to a diet of 600 g/day of duck-meat for 4 wk, after which body composition, hematological variables, and serum metabolic and lipid profiles were investigated to determine if there was a relationship between duck-meat consumption and adult disease risk factors. The results revealed that high amounts of duck-meat intake did not negatively alter body indices such as body weight, fat mass, body mass index (BMI), % body fat or waste-to-hip ratio (WHR). Furthermore, there were statistically insignificant changes in the number of blood cells, although this number did increase significantly following intake of duck-meat. Moreover, general decreases in serum metabolic parameters were observed, but none of these changes were significant with the exception of the concentration of blood urea nitrogen (BUN). The serum concentrations of LDL-cholesterol also showed a statistically significant decrease by 5.86%. Therefore, this study suggests that the ingestion of duck-meat not only significantly increased the RBC count but also decreased BUN and LDL-cholesterol concentrations in adult males.

This study was performed to investigate the growth rate, hematological and serological changes of the rats when they were fed with the high fat diets supplemented with or without the tannic acid for five weeks. Thirty-two Sprague-Dawley male rats(235.7\pm10.7g\;of\;body\;weight)$ were randomly divided into four groups, control group and three treatment groups(T1, T2 and T3). Rats in control group were fed with the high fat diet containing $15\%\;lard,\;1\%$ cholesterol and $0.5\%$ sodium cholate(wt/wt) which was modified from the formula of American Institute of Nutrition (AIN)-76 diet and rats in treatment groups were fed with above diet supplemented with $0.25\%(T1),\;0.5\%(T2)$ or $0.75\%(T3)$ of tannic acid(wt/wt), respectively. The supplementation of tannic acid(TA) did not affect the final body weight, gain of body weight and feed intake of rats in both control and treatment groups. The numbers of red blood cells, hemoglobin concentrations and hematocrit values in blood of rats showed no significant differences between control group and treatment groups. The glucose concentration and albumin/globulin(A/G) ratio of rats in treatment groups were slightly lower than that of control group without significance. The values of total protein, albumin and globulin showed no significant differences between control group and treatment groups. The values of total cholesterol, low density lipoprotein­cholesterol and atherogenic index in sera of rats in treatment groups were much lower than that of control group without significance. The values of triglycerides in sera of rats in T3 group were significantly lower than that of control group (p<0.05). The values of AST and ALT in sera of rats in T3 group were significantly lower than that of control group (p<0.05). Thus supplementation of tannic acid to high fat diet could be effective to reduce the serum lipid levels such as total cholesterol, high density lipoprotein-cholesterol and triglycerides which were regarded as to cause the cardiovascular diseases.
