    초록

    This study was done to investigate the effect of age and dietary linolenic acid content and the linolenic acid/linoleic acid(LNA/LA) ratio on the lipid metabolism and formation of PGI2 and TXA2. The male Sprague-Dawley rats were fed 6 different with 0.2, 0.4, 0.6 of LNA/LA ratio within either 8% LNA(high LNA) or 4% LNA(low LNA) of fatty acid content for different feeding period(1, 4, 12 month). The dietary fat used were sesame oil, perilla oil, soybean oil and beef tallow. The concentration of serum total lipid, total cholesterol and HDL-C were increased with aging. Triglyceride concentration was decreased in 0.2 ratio of LNA/LA. The lipid content of liver showed similar tendency to that of serum. The ratio of PGI2/TXA2 was increased in 1 month rats and antithrombotic effect was reduced significantly with increasing age. The PGI2/TXA2 ratio was tended to be higher in diet of 0.2 and 0.4 LNA/LA ratio at high LNA level and in diet of 0.6 LNA/LA ratio at low LNA level. Especially PGI2/TXA2 ratio was increased linearly with rising LNA/LA ratio at low LNA level. It seemed that the LNA content and LNA/LA ratio had interaction to increase the antithrombotic effect bychanging TXA2 synthesis. And the dietary fatty acid related effect lowering the serum and liver lipid content, excepting triglyceride, was increased when dietary n3/n6 ratio was high(0.6) at both high and low n3 level. Therefore, it could not be recommended to consume large amount of n3 fatty acid or high ratio of n3/n6 to prevent cardiovascular diseases. These results suggested that the dietary fatty acid ratio of n3/n6 could be determined based on the n-3 content of dietary fat to reduce the risk of cardiovascular disease.

    We have examined the antigen specificity in orally tolerant mice fed with the casein(CN) diet. In contrast to previous reported results of studies on oral tolerance, these mice responded poorly to ovalbumin(OVA) and ovomucoid(OM), as well as $\alpha$ sl-enriched fraction of these cells suppressed anti $\alpha$ sl-CN antibody production of naive mice, but could not significantly suppressed antibody response of previously immunized recipient mice. These results indicate that oral tolerance was not medicate through suppressor T cell activities.

    초록

    This study was performed to investigate the effect of dietary chitin & chitosan on cadmium (Cd) toxicity and lipid metabolism in rats. Forty-two male rats of Sprague-Dawley strain weighing 137 $\pm$ 2g were blocked into 6 groups according to body weight, and were raised for 4 weeks. Cadmium chloride was given at the level of 0 or 400ppm in diet and chitin and chitosan were given at the level of 0 or 4%(w/w) of diet. The results are summarized as follow. Chitosan decreased the toxicity of Cd on liver, kidney and femur and increase the Cd content of fecal excretion. Chitosan increased the lipdi & cholesterol content of fecal excretion by combining with lipid and bile acid. Chitosan decreased lipid, cholesterol and TG content in serum and liver by combining with lipid and bile acid. Chitin was less effective than chitosan in decreasing of Cd toxicity and lipid content of rat.

    초록

    In order to investigate the effect of Korean green tea, oolong tea and black tea beverage on the antioxidative detoxification in cadmium(Cd) poisoned rat liver, male Sprague-Dawley rat weighing 143 $\pm$ 3.2g were divided into control and experimental groups. The experimental groups were fed standard diet containing 40ppm Cd and were given distilled water(CD), 5% black tea(BT), oolong tea(OT) and green tea(GT), respectively. Tea beverages were extracted from 5G dry leaves of teas in 100ml hot distilled water by the treatment at 85 $^{\circ}C$ for 3 min. Liver xanthine oxidase(XOD) activity was increased by the administration of Cd except GT group. Liver superoxide dismutase(SOD), glutathione peroxidase(GSH-px), glutathione S-transferase(GST) activities were decreased by te administration of Cd but did not decreased by the administration of green tea(in GT group). Vitamin E and reduced glutathione contents were significantly decreased in Cd administered groups. Liver lipid peroxide value in Cd administered groups were increased compared to control group, but was not increased in GT group. Serum glutamic oxaloacetic transaminase(GOT) activities in CD, OT, BT groups were higher than control, but that in GT group was similar to control group. Serum glutamic pyruvic transaminase(GPT) activity was not significantly different among various groups. It was concluded that green tea might alleviate peroxidative damage in Cd-administered rat liver by reinforcing antioxidative detoxification system.

    Dietary iodine intake and urinary iodide excretion were meassured from 110 patients with various thyroid hormone diseses(hypothyroidism, hyperthyroidism, simple goiter and thyroid adenoma) and 67 normal control subjects. Iodine intake was assessed on the 24-hour recall dietary data using the compiled lists of food iodine values developed from various countries. Urinary iodide concentrations of drink water samples were measured with the iodide-selective electrode. The average iodine intake of the thyroid patients was 411 $\mu\textrm{g}$ , which was 87% higher(p $\mu\textrm{g}$ ). Patients with hyperthyroidism and hypothyroidism or simple goiter excreted the most(0.6442ppm) amount of iodide respectively in the urine, with the control subject in the middle(0.5229ppm). Iodide concentrations of the drinking water samples were found to be in the range of 0.0015ppm to 0.0214ppm, which seemed to vary depending on the kind(underground water vs public water) and the location.

    Nonobese NIDDM patients were studied were studied with respect to changes in visceral protein status, serum glucose and lipids and insulin secretion capacity before and after intake of enteral formula. Patients with renal or hepatic disease, gastrectomy, malabsorption, weight gain over past 6 months and poorly controlled blood glucose level were excluded. Eighteen patients served as case and administered, in addition of their usual diet, 400ml of enteral formula for 8 weeks. Another 18 patients participated in controls and had usual food intake for 8 weeks. In the begining, the levels of fasting and postprandial glucose, glycated hemoglobin, triglyceride, HDL, LDL, total cholesterol, albumin, total protein and transferrin and glucose response area on oral glucose tolerance test were not different between two groups. The response areas of insulin, C-peptide and free fatty acid and serum IGF-1 level were higher in the case than in the control group. Energy intake of patients given enteral formula exceeded their estimated energy requirements(108%) and they consumed a mean of 112g protein per day. Patients given enteral formula showed an increase in body weight(4.4%), serum transferrin(10%), IGF-1(13%) and triglyceride(34%) while controls showed no changes in those parameters at 8 weeks compared to initial values. There were no significant changes after 8 weeks in the levels of glucose, glycated hemoglobin, HDL, LDL, total cholesterol, total protein and albumin and response areas of glucose, insulin, C-peptide and free fatty acid in both groups compared to initial values. This study suggests that nutrition supplement with enteral formula can increase body weight and visceral protein status in nonobese NIDDM patients without changes in blood glucose. However, excessive calorie intake could temporarily increase serum triglyceride. In addition, this study indicates that serum transferrin and IGF-1 are more sensitive indicators to changes of protein intake than serum albumin and total protein.

    This study was performed to study the effects of dietary factors on breast and cervical cancer incidence in female Koreans. The subjects were 60 breast and 109 cervical cancer patients recruited from five general hospitals in Seoul. Food intake, anthropometric measurement, and blood compositions were studied through personal interview and using medical records, from August 1991 to September 1992. Body weight, body mass index, triceps skinfold thickness and body muscle mass were at upper limit of normal value, which suggest that these patients had a tendency of overweight. The levels of hemoglobin and hematocrit of the patients were below the normal values. The values of serum protein, albumin, and calcium were in the normal range but close to the lower bound. Therefore the nutritional status assessed by blood composition seems to be marginal. The results of diet history showed that most of the nutrient intake of the subjects met with RDA. The fat intake were 22.9-36.9g/day which supplies about 15-16% of total calories. The results of this study do not agree with those reports of western societies which showed the positive correlation between calorie and fat intake and the incidence of breast and cervical cancer. Even through the calories and fat intake of the subjects were not high, it was higher than national average, especially in breast cancer patients. From this study, dietary factors does not seem to be a major risk factor in cancer incidence in Korea. However, the tendency of the increasing consumption of fat could be a contributing risk factor together with overweight.
