To elucidate the effects of an obesity control program on body composition and serum lipid levels, 31 obese elementary students (male: 25, female: 6) residing in the Gyeonggi area were evaluated and their body composition, serum total cholesterol, HDL-cholesterol, LDL-cholesterol and TG (triglyceride) were analyzed. The average age, height, weight and BMI (body mass index) were $11.52{\pm}1.00\;yrs$, $151.96{\pm}8.04\;cm$, $68.21{\pm}9.03\;kg$ and $29.40{\pm}1.79\;kg/m^2$ for the males, respectively, and $11.17{\pm}1.17\;yrs$, $147.83{\pm}5.15\;cm$, $65.05{\pm}10.86\;kg$ and $29.62{\pm}3.24\;kg/m^2$ for the females, respectively. There was a significant decrease in BMI for males (p<0.001) and females (p<0.05). There were also significant changes in all of the biochemical levels evaluated before and after the study. Specifically, the total cholesterol, LDL-cholesterol and TG level decreased after the obesity control program, while the HDL-cholesterol level increased after the program. These results indicate that obesity control programs do change the BMI, serum total cholesterol, HDL-cholesterol, LDL-cholesterol and TG levels in obese elementary students. Thus, obesity control programs are urgently needed to prevent degenerative disease and decrease obesity among children in elementary school.

It is known as that onion is antioxidation effect, antibiotic effect, blood pressure decreasing effect and reducing serum cholesterol levels. This research about effect that onion concentrate gets blood cholesterol levels and body composition. Subject was 17 adult men of hyperlipidemia. Age distribution of investigation subjects were average 49.4 years old by 40~56 years old, and average height and weight were 167.6cm and 75.5kg each, BMI was 26.9kg/$m^2$, and BMR was 1,460.6$\pm$87.5㎉, and AMC was 25.0$\pm$1.05cm, and BCM was 41.0$\pm$2.79cm. In the meantime, the body muscle was 53.7$\pm$3.7kg, and fat mass was 18.7$\pm$3.8kg, and intracellular fluid was 26.6$\pm$1.8kg, and extracellular fluid was 12.8$\pm$0.9kg. The % body fat was 24.6$\pm$3.8%, and fat distribution was 0.9$\pm$0.0%, and the obesity degree was 125.4$\pm$8.2%. Vegetables, seaweeds, fruits and juices increased by change of dietary life and greasy foods, instants, breads, rices etc. decreased or there was no change, fast foods and eggs were no change. Also, subject previewed that guidance about stress, smoking, drinking and beverage intake need. If compared the nutrient intake amount with before onion concentrate allowance, it was similar level almost without significant. Energy, calcium and riboflavin are lower than the RDA for koreans. After 3 months, the levels of plasma total cholesterol, triglycerides had decreased significantly : 15.0%, 31.2% respectively. And the HDL-cholesterol and LDL-cholesterol levels also showed a marked reduction of 6.8%, 8.7% respectively. Plasma lipid level change by onion concentrate supplement would can know that case of triglyceride more greatly than plasma cholesterol. The pH and Na+ level of plasma were low significant since 8 weeks after, and $K^{+}$ level increase significant. While $Ca^{++}$ level was low significant after 1 month, there was no change since 2 months after, but nC $a^{++}$ level was low significantly. Plasma $Mg^{++}$ level was no change and nM $g^{++}$ level was low significant after intake.e.e.e.e.e.

This study was designed to investigate the effects of calcium supplementation on calcium metabolism in seven healthy college women, aged from 19 to 21 years old. For this purpose, metabolic studies were conducted for two weeks. During the first week, the subjects ate experimental diet which nutrients composition was similar to their usual intake. And during the consecutive second week, they ate the same experimental diet supplemented with 500mg of calcium daily. The results were summarized as follows ; 1) Fecal excretion of calcium increased significantly (P<0.05), but urinary excretion of that did not show any change after supplementary intake of calcium. 2) Mean apparent calcium absorption was 28.5% and retention was 182mg/day when subjects ate the experimental diet without calcium supplementation. Calcium retention was significantly ate the experimental diet without calcium supplementation. Calcium retention was decreased to 24.1% by additional intake of calcium. 3) Phosphorus balance did not show any change after additional intake of calcium. 4) Serum calcium level was also not changed by additional intake of calcium. 5) Serum calcium level increased significantly(P<0.05) but serum phosphorus level did not show any change after additional intake of calcium. The above results showed that supplementation of 500mg calcium daily can be helpful to increase calcium retention as well as the peak bone mass in young women eating usual Korean diets.

The effects of dietary cellulose on the lipid metabolism in albino rats were observed, especially the effects of dietary cellulose from three different sources; cereal, vegetable and pure-cellulose. The results were summarized as follows. 1. Dietary cellulose from rice bran and vegetable resulted in lowering of reserved lipid in the body and the effect of rice bran was remarkable as compare to that of vegetable. 2. But the fatty acids composition in serum, liver, gastrocnemius, small intestine and epididymal fat pad was unchanged by dietary cellulose. This means the effect of dietary cellulose was only to change the body fat in quantify and not in quality. 3. Cellulose from rice bran increased serum cholesterol content and maintained medium level of serum total lipid. Cellulose from vegetable decreased serum total lipid and cholesterol content. Pure-cellulose decreased also serum total lipid and cholesterol content but the effect was not as low as vegetable cellulose. 4. It need to be further investigated on the different effects of cellulose from three sources on serum cholesterol content, particularly the increasing effects of rice bran.

This study was designed to confirm the effect of dietary protein level and oral administration of tryptophan on brain serotonin metabolism. Two animal experiments were conducted. The objectives and results of research were as follows : In the first experiment, it was investigated whether administration of reserpine to Sprague-Dawley rats fed 6% or 20% casein diet induced decrease in serum tryptophan and large neutral amino acid(LNAA) concentrations, tryptophan/LNAA concentration ratio, brain tryptophan, serotonin and 5-hydroxyindoleacetic acid(5-HIAA) contents. Brain serotonin content of 6% casein diet group was lower than those of 20% casein diet group. Both 6% and 20% casein diet groups administered with reserpine to induce the analogous depression, showed the notable decrease in brain serotonin content when they were compared with 20% casein diet group not administered with reserpine. Serum tryptophan/LNAA ration and brain 5-HIAA content showed a tendency similar to the change of serotonin content, but the mean difference among all groups was not significant. From these results, it could be said that when the dietary protein level was low, brain serotonin content was decrease. The second experimnt was to see the change in serum tryptophan concentration and tryptophan/LNAA ratio and brain tryptophan, serotonin and 5-HIAA content when tryptophan was administered orally to the animals treated with reserpine. Serum tryptophan concentration tended to increase in both reserpine-treated 6% and 20% casein diet groups administered with tryptophan, especially in the 6% casein diet group. Serum tryptophan/LNAA concentration ratio tended to incrase in reserpine-tteated 6% casein diet group, while decrease in reserpine-treated 20% casein diet group. Brain tryptophan content was increased in both reserpine-treated 6% and 20% casein diet groups. However, brain serotonin content of reserpine-treated 6% casein diet group showed a tendency to decrease, while that of reserpine-treated 20% casein group increase. Consequently, the effect of tryptophan administration on increase of brain tryptophan and serotonin content in animals treated with reserpine was far more excellent in 20% casein diet groups. It was concluded that dietary protein intake and tryptophan administration increase brain serotonin level. Accordingly, it was possible to confirm that brain function, particularly in aspect of behavior related to the serotonin, was changed with manipulation of dietary composition.

Liver is an oragan which has various functions. For this functions in liver disease change variously, many methods of examination of them are invented. Each liver disease impairs these functions diversly rather than uniformly, thus it is possible to differentiate each disease by using various methods of testing it. Liver has high reproductive capacity and despite partial impairment of its function localized disease may not show any abnormality in liver function test due to compensation of remaining intact tissue of the liver. Thus the result of liver function test should be interpreted under adequate clinical investigation with other test, not depending on the liver function test only. This thesis deals with the composition, distribution in living body and clinical significance of liberating enzyme, GOT, GPT, and LDH which are included in serum enzyme that show abnormality in liver disease.

Rainbow trout (Oncorhynchus mykiss) were treated with ultrasonic (40kHz) and microbubble. The organic serum components, glucose were decreased compared to control at microbubble single treatment (M) and ultrasonic treatment (UL), but glucose concentrations in fish serum of all experimental groups analyzed in this study were also within the normal range. The organic serum components, cholesterol and total protein were no significant change by ultrasonic and microbubble treatment. There were no significant changes in the lysozyme activity on ultrasonic and microbubble treatment. Serum bactericidal activity decreased on ultrasonic single treatment (UL) compared to the control (P<0.05), but the numbers of bacterial colonies were significantly lower than those in the negative (PBS). The results of this study indicate that ultrasonic and microbubble treatment did not have a critical effect on the serum composition and innate immunity of O. mykiss, and that it is a way to do not significant stress on the fish body as a countermeasure against sea lice.

This study was conducted to investigate the effect of dietary thyroid hormone (T$_3$and T$_4$) on growth, feed conversion ratio and serum T$_3$or T$_4$concentration of broiler chicks. Zero to six week-old broiler chicks were randomly allocated into seven treatment groups for feeding trials with three replication : control, T$_3$(0.1), T$_3$(1.0), T$_3$(5.0), T$_4$(0.1), T$_4$(1.0), T$_4$(5.0) ppm group. Concentrations of T$_3$and T$_4$in serum were analyzed. The weight gain of T$_3$(1.0), T$_3$(5.0) and T$_4$(5.0) groups were significantly lower than that of control. No statistically significant adverse effect was observed in other groups (p〉0.05). Feed intake was significantly lower in T$_3$(0.1, 1.0 and 5.0) and T$_4$(5.0) than in control group (p〈0.05), and the feed conversion ratio had a similar trend to the feed intake change. The contents of liquid and abdominal fat pad in carcass were significantly decreased in all T$_3$and T$_4$groups (p〈0.05). T$_3$and T$_4$concentration in serum was significantly increased at over 1.0ppm of the hormone supplementation level. As T$_3$addition level increased, T$_4$concentration in serum reduced ; however, T$_3$in serum was directly proportional during fasted were slightly increased when T$_3$or T$_4$was added to broiler diets.

Objectives : This study was performed to investigate the effects of Rhizoma Arisaematis water extract on lipid and glucose metabolism and histochemical change of obese rats. Methods and materials : 10 rats were divided into normal, control and RA (Rhizoma Arisaematis) groups. We fed the control group a high-fat diet and administered normal saline for 8 weeks. We fed the experimental group of rats a high-fat diet and administered an extract of Rhizoma Arisaematis for 8 weeks. At the end of the experiment, the rats were sacrificed to determine their chemical composition. The groups were examined for effects on blood serum lipids, blood sugar, blood insulin concentration and epididymal fat cells. Results : 1. Serum total cholesterol, triglyceride, HDL-cholesterol and glucose of the RA group decreased compared with those of the control group. These decreased rates were significant(P<0.05). 2. Serum LDL-cholesterol, total lipid, free fatty acid and the average size of epididymal fat cells of the RA group decreased compared with those of the control group. These decreased rates were significant(p<0.01). Conclusions : These results suggest that RA may be used to prevent or cure the obesity iniduced by a high-fat diet.
