The Artichoke extract at 10% was used to add in drinking water to understand its effect on Aflatoxicosis of chickens. The Artichoke extract at the dose of 6 ml per liter of drinking water was given (experiment group) or not (control group) and to Hybro chickens (150 birds), during the first 49 days of life. Also, the chickens were fed with foodstuff containing 200 ppb or 500 ppb Aflatoxin $B_1$. Results showed that, the chickens having Artichoke extract: (1) Had overcome the growth retardation caused by the toxin at concentration of 200 ppb and 500 ppb of Aflatoxin $B_1$ (an addittonal weight gain of about 200-400 g/bird). (2) The feed conversion was improved (a reduction of 200-400 g of feed per kg of bird living weight). (3) Aflatoxicosis lesions were mild in the chickens, which fed 500 ppb of Aflatoxin $B_1$ or not found in those having the toxin 200 ppb. The blood examinations at 28th and 49th days of the trial gave the following results: (1) The Artichoke extract had an effect of suppressing the changes of blood cell numbers, hemoglobin amount. packed cell volume. leukocyte formula that were caused by Aflatoxin $B_1$. (2) The Artichoke extract had an effect of suppressing the diminution oj sugar, protein levels and the increase of the levels of GOT, GPT, alkaline phosphatase and bilirubin in the blood of intoxicated chickens. There was not or very Jew residue of Aflatoxin $B_1$ contained in the liver and muscle of chickens intoxicated by Aflatoxin $B_1$ having Artichoke, that was much lower than the allowed level in animal products.

Chicory is used popularly. We use leaves of the plant as ordinary mea1, and roots as a substitute of tea materials. It also has been asserted that it has clinical effects on weakness, hepatic disease, diabetes, etc. However, experimental evidences are so insufficient that we started these studies. For antiinflammatory activity, MeOH Ex. was orally administered to rats, and decreased amounts of paw edema induced by carrageenan injection were measured. For bile secretion increament, rats were administered total MeOH, EtOAc fraction, and BuOH fraction Ex. respectively. One hour later, bile ducts were cannulated, and we collected bile every 20 minutes for 4 hours. For hepatoprotective activity, CCl$_4$-intoxicated mouse were treated with MeOH Ex., then s-GPT, S-GOT, and liver weight were measured. For antidiabetic activity, rats were induced diabetes by streptozocin 45mg/kg(i.v) injection. One week later, 1000mg/kg of total MeOH Ex. of chicory root was orally administered. We divided rats into three groups. Group 1 rats were administered only once, group 2 ones once a day for one week, and group 3 ones for three weeks. The concentrations of serum glucose were measured before and after administration. For antihypertensive activity, SHR were administrated total MeOH Ex. of chicory once a day for 8 days, and were measured blood pressure on 1st, 3rd, 6th and 8th day. Total MeOH, EtOAc fraction, and BuOH fraction Ex. increased bile secretion in rats, and decreased liver toxicity induced by CCl$_4$ in mouse. Total MeOH, Ex. of chicory roots has antiinflammatory effect, and decreased blood glucose concentration in group 2 and 3 rats. It was revealed not lowering blood pressure significantly in SHR.

The effects of salinity on survival, oxygen consumption, and hematological response of greenling Hexagrammos otakii, mean body weight 147.1±3.8 g, were investigated under salinity conditions of 33.4 (control), 33.1, 32.8, 32.2, 31.0, 28.7, 23.9, 14.5, and 3.8 psu, to evaluate physiological effects in relation to changes in salinity. The survival and hematological responses of fish were measured at each salinity after 96- and 24-h exposures. The oxygen consumption rate (OCR) of fish was measured in triplicate under conditions of stepwise salinity exposure (33.4→33.1→32.8→32.2→31.0→28.7→23.9→14.5→3.8 psu) with an interval of 24 h at each salinity, using a continuous flow-through respirometer. No fish mortality was observed in the range of 33.4 to 14.5 psu, but the survival rate was reduced to 53.3% at 3.8 psu after 96 h of exposure. The OCRs did not significantly differ in the range between 33.4 to 28.7 psu (P>0.05), but significantly increased at 23.9 and 14.5 psu, and then dramatically decreased at 3.8 psu compared to the control (P<0.05). Hematological variables, such as glucose, glutamic pyruvic transaminase (GPT), hematocrit, and Na⁺, were affected by reduced salinity. This result may be applicable for habitat and culture management of greenlings.

Background and Objectives : Although the incidence of allergic rhinitis has increased specific therapeutics with a certain medicine is not well developed yet. In therapeutics of allergic rhinitis, limited medicines just have been used in the clinin. Sochungyong-tang has been a widespread medicine for allergic rhinitis. However, okbyeongpung-san has been taken for raising immunity. In medical treatment of allergic rhinitis, raising immunity is a necessary part of the process. In this reason, this study aimed to find out therapeutic effects of combination of sochungyoung-tang and okbyeongpung-san extract on allergic rhinintis of nasal tissue in rats. Materials and Methods : The Sprague-Dawley male rats, about 200g of body weight, were divided into three groups: the normal group, the control groups, and the sample groups. With the Levine and Vaz method, the allergic reaction was induced with ovalbumin as antigen in the intraperitoneal route. Rats of the sample groups were treated with 2cc of sochungyoung-tang plus okbyeongpung-san extract once a day for 28days. I observed historical changes in nasal tissue. I also found changes in the segment of lympocyte and neutrophil of Leukocyte and erythrocyte. I used the statistical methods of post Hoc test(p<0.05) Results : The increase of the goblet cell and mucous secretion in the sample groups was rare when compared to the control groups. Effects of sochungyoung-tang plus okbyeongpung-san extract on the liver function were also studied in rats. Treatment of sochungyoung-tang plus okbyeongpung-san extract did not affect GOT and GPT. The number of lymphocyte was decreased, while the number of erythrocyte was increased in sample groups. Conclusion : This study shows that sochungyoung-tang plus okbyeongpung-san plus okbyeongpung-san extract has considerable effects on allergic rhinitis.

In this study, we investigated the effects of obesity index on the risk factors of chronic diseases in obese children. The subjects were male and female children aged 9 to 12. The average obesity index was 147.7$\pm$13.8% in boys and 147.6$\pm$16.5% in girls. The average percentages of body fat was significantly higher in boys(33.9$\pm$5.7%) than in girls(30.7$\pm$4.4%). It was found that 26% of subjects had abnormal serum GOT and GPT values. Percentages of subjects at risk of cardiovascular disease(CVD) based on corresponding criteria of TG, T chol, HDL chol, and LDL chol were 28.6%, 28.6%, 45.5% and 42.7%, respectively. The risk of CVD was increased with the degree of obesity, which was not significant. The AI(atherogenic index) was higher in boys(4.6$\pm$2.3) than in girls(3.6$\pm$1.2). The serum T chol and LDL chol levels of subjects whose mother are in thirties were significantly higher than those of subjects whose mother are in fourties. The T chol levels of subjects who had mother with job were significantly higher compaired to those of subjects who had housewife mother. The results indicated the urgent need of nu tritional management for the obese children to prevent further devel opment of childhood obesity and hyperlipidemia. Based upon this study, devising method and media for the mother nutritional education as well as for the children nutritional education is required for better growth and health promotion of primary school children.

Anti-diabetic effect of various fractions of Cordyceps militaris (CM), CCCA (crude cordycepin containing adenosine), CMESS (ethanol soluble supernatant), and cordycepin were evaluated in streptozotocin (STZ) induced diabetic mice, CMESS showed potent inhibitory activity of 34.7% in starch-loaded mice (2 g/kg) while acarbose as a positive standard exhibited 37.8% of inhibition rate. After 3 days administration (50 mg/kg), cordycepin (0.2 mg/kg), and acarbose (10 mg/kg) dramatically reduced blood glucose level (inhibition ratio: 46.9%, 48.4% and 37.5% respectively). CCCA that has high contents of cordycepin (0.656 mg/4 mg) did not influence on reducing blood glucose level. The proliferation of splenocytes and peritoneal macrophages derived from STZ-induced diabetic mice administered samples were evaluated out by addition of mitogens to see the stability of the usage of these herbal medicines. Proliferation of T-lymphocyte was significantly decreased; while NO production was increased more than two fold to STZ control in the cordycepin-administered group. Changes of serum enzyme levels of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) were also evaluated. Cordycepin administered group was appeared to acarbose. We conclude that CMESS and cordycepin may be useful tools in the control of blood glucose level in diabetes and promising new drug as an anti-hyperglycemic agent without defects of immune responses and other side effects.

The effect of ginseng administration on the patients of acute viral (B type) hepatitis has been oberved and the results were as follows. The albumin/globulin ratio of the ginseng administered group has significantly improved 4 weeks after admission while that of control group has not been improved suggesting that the ginseng might be effective in improving the protein metabolism. The thymol turbidity test again gave a similar result. Recovery of the disorder of bilirubin metabolism was also accelerated in the ginseng administered group compared with control group. The raised bilirubin value of the former returnedto the normal value 2 week after admission while that of the latter reached to normal 4-5 weeks after admission. However no significant difference of the bilirubin level between ginseng treated and non-treated groups could be observed. Cholesterol metabolism is also stimulated in ginseng administered group. The lowered cholesterol level of the ginseng group returned to normal 3-4 weeks after admission while that of latter reached to normal 5-6 weeks after admission. The raised S-GOT and S-GPT levels of the ginseng treated group returned to the normal value 3-4 weeks after admission while those of control group rehimed to normal in 5 weeks after admission suggesting that the ginseng improved impaired liver function. The improvement of the raised transaminase level seemed to be accelerate6 by the ginseng administration, however, no significant difference of the transaminase level between the ginseng treated and non-treated group could be observed. A significant effect of ginseng on the raised alkaline phosphatase level was observed. From the above results, it seemed that ginseng might stimulate the improvement of the disturbance of liver function, particularly at the early phase of its development of acute liver disease suggesting that panax ginseng might play a significant role in preventing the disease developing to be chronic.

This study was undertaken to find out the bio-effects due to be a radiation fractionated exposure. The experimental animals were divided into the control group and the radiation exposure groups of 20cGy, 40cGy and 80cGy with 220 male Sprague-Dawley rats at 6 weeks old. The radiation exposure groups were fractionated exposed from each 20cGy, 40cGy and 80cGy for every 5 days. The chromosome aberrations, the frequency of SCE, the changes of body weight, hematological values and enzyme activities were investigated for the fractionating exposure times and the time after fractionated exposure. The results were summarized as follows 1. The body weight of the radiation exposure groups were significantly decreased compared with control group according to the increasing fractionated exposure times, and it was the lowest values at the immediately after the end of the fractionating exposed, but it was recovered with the level of control group at 3rd weeks gradually increased 1st week after fractionated exposure. 2. The values of WBC, RBC, Hb and Hct in the radiation exposure groups were significantly decreased than those the control group, but the values of GOT, GPT, ALP, and LDH in the radiation exposure groups were significantly increased than those of the control group. 3. The frequency of chromosomal aberration were increased according to the increasing fractionated exposure dose, and it showed the highest at 5th days after fractionated exposed. The types of chromosomal aberration were occurred such as a numerical abnormality, deletion, break and duplication, it was not recovered immediately and maintained high frequency than the control group. 4. The frequency of SCE were significantly increased according to the increasing fractionated exposure dose in 20cGy, 40cGy and 80cGy groups. But it was recovered the level of control group at 7th days after fractionated exposure. According to the above results, this study could confirm that the frequency of chromosomal aberration and SCE were increased with fractionated exposure dose, the other hand, the changes of body weight, hematological values and enzyme activity values were significantly affected according to the increasing fractionated exposure dose.
