The present study was devised to determine the effects of vitamin E and selenium (Selevit) on body weight, organ weight, hematological values and biochemical parameters in the orchidectomized (Orch) rats. Intact group (n=15) received no treatment and operation. Orch+Selevit received operation and Selevit. The body weights of each group increased, but that of the Orch＋Selevit group were significantly lower than those of all the other groups. There were significantly different decreased (p<0.001) of body weights between Orch＋Selevit group and all the other groups. Also, organ weights such as heart, liver, spleen, kidney, lung and skeletal muscle were measured. The heart and liver weights in the Orch＋Selevit group were significantly different decreased (p<0.001) in comparison with those in the Intact and Sham groups. The kidney weights in the Orch＋Selevit group were significantly different decreased (p<0.01, p<0.001) in comparison with those in all the other groups. The number of white blood cell (WBC) was significantly higher (p<0.05) in the Orch＋Selevit group than in all the other groups. The hematological values of 12 parameters were not significantly different in any of the groups. The concentrations of serum total protein, albumin and alkaline phosphatase only increased significantly (p<0.05, p<0.01) in the Orch＋Selevit group as compared to that in the Orch group. We conclude that Selevit was significantly decreased the body weight in the Orch rats. Our findings suggest that Selevit may influence the process of lipid packaging and absorption in the Orch rats.

The edible mushroom Agaricus blazei Murill is known to have many physiological functions, including antitumor, antiviral, and anti-inflammatory effects. Aqueous extracts were obtained by extracting A. blazei in water at $90^{\circ}C$ for 15 h, followed by spray-drying with dextran at a 70:30 ratio. In this study, we examined the immunomodulatory effect of A. blazei Murill water extract (ABM) in BALB/c mice. Mice were administered orally with 4, 20, and 100 mg/kg of ABM for 21 days. ABM-treated mice did not show significant differences in body and organ weights compare to saline-treated control mice. Splenocytes isolated from ABM-administered mice revealed similar levels of cellularity and proliferation compared to control mice, whereas they showed increased natural killer (NK) cell activity and decreased IL-4 and IL-12 production. Different from in vivo results, splenocytes isolated from normal mice showed increased proliferation and $INF-{\gamma}$ production following ABM treatment in vitro. In addition, ABM treatment enhanced macrophage proliferation and nitric oxide (NO) production in a dose-dependent manner. However, ABM had no effect on LPS-induced NO production. These results suggest that A. blazei modulates immune function by increasing NK cell activity and macrophage function.

The present study was undertaken to evaluate the effects of 50% buckwheat diet on the body weight, organ weight, urine albumin, urine glucose, plasma glucose and plasma lipid in normal rats and diabetic rats treated with streptozotocin(STZ). The food intake, body weight, the level of urine glucose in diabetic buckwheat groups were not significantly different with diabetic control group. The level of urine albumin was lower in raw and steam buckwheat group than in the diabetic control group. Compared to the normal control group, liver and kidney weights were heavier in the diabetic groups. Pancreas weight was heavier diabetic buckwheat groups than in normal and diabetic control groups. Fasting plasma glucose level of diabetic buckwheat groups significantly decreased by 18-37% compared with the diabetic control group. Plasma triglyceride level of diabetic buckwheat groups significantly decreased by 34-50% compared with the diabetic control group. Plasma total cholesterol level of diabetic buckwheat groups decreased by 15-27% compared with the diabetic control group. The level of HDL-cholesterol was not affected by buckwheat diet. These results indicate that buckwheat is an effective therapeutic regimen for the control of metabolic derangements in diabetics.

Elucidation of the metabolic pathway due to 50% dietary restriction carried out in this study. Seventy male and female wealning rats, weighed $43{\pm}2g$ were divided into seven groups, 10 rats each. Twenty rats, ten males and ten females were sacrificed every three weeks after 50% dietary restriction for whole length of the experiment, nine weeks. Pair-feeding was employed in this study. According to the increment of the dietary restricted period, the body and organ weights were decreased. Especially liver and spleen were mostly shrinked in their weights, and brain was the most stable organ in account of dietary restricted effect. In comparison nitrogen retention between restricted and unrestricted groups, the former showed lower than the later but tubulated into the rate of Nitrogen retention per gram of body weight, reverse was true in this respect. In regardness of the experimental organs, spleen revealed the most fast change and the brain the most slow change their content of RNA and DNA in account of the 30% dietary restriction. Hematological investigation did not show any anemic conditions in both restricted and unrestricted groups. Also serum albumin contents A/G ratio, did not effect due to 50% dietary restrictions.

To study the effects of diets containing Ginseng extracts as foods, Sprague-Dawley strain rats were fed several diets containing the Ginseng extracts(Ginseng nectar, Ginseng orange juice, Ginseng drink) for 12 week. The Ginseng diets contained 555 mg or 1,110 mg of Ginseng extracts per kg of the diet. During the feeding, growth rate, feed efficiency ratio, organ weight, hematocrit value, SGOT and SGPT activity were compared with those of the control rats. As results of growth rate, feed efficiency ratio, organ weight, hematocrit value and SGPT activity showed no statistical significance between Ginseng fed animals and the controls. The experimental animals showed slightly lower SGOT activity and higher serum cholesterol than the controls did. The difference was, however, not statistically significant. No abnormalities of liver, spleen and kidney tissues were observed in the rats fed with the diets containing the Ginseng extract. As result of swimming test, a statistically significant increase of the swimming time was observed in the experimental animal groups, especially in Group V.

The purpose of this study was to investigate the effect of germinated buckwheat on blood pressure, plasma glucose and lipid levels of spontaneously hypertensive rats(SHR). The male and female SHR were divided into two groups. After feeding the germinated buckwheat diet(50%, w/w) ad libitum for 6 weeks, the weight gain of the germinated buckwheat group in male rats was higher than those of control group. Systolic blood pressure of the germinated buckwheat group in male rats was significantly decreased at 6 weeks by 3%. The fasting glucose levels of the germinated buckwheat group had a tendency to be lower compared with those of the control group. Total cholesterol, HDL-cholesterol and HTR of female SHR fed the germinated buckwheat diet were significantly increased compared to the control diet. Atherogenic index of the germinated buckwheat group was decreased in males(ns) and females(p<0.05) than those of the control group. From these results the germinated buckwheat might be useful for anti-hypertensive and anti-hyperlipidemic agents.

This study was conducted to evaluate the effects of dietary softwood by-products extract on growth performance, organ weight and intestinal microbes in organic broiler chicks. Five treatments were assigned to 200 broiler chicks with four replication, allocating 10 broiler chicks in each replication. Dietary treatments included control(Organic diet), +C(Organic diet + antibiotics), T1(Organic diet + softwood by-product powder 3.0%), T2(Organic diet + softwood by-product extract 0.05%) and T3(Organic diet + softwood by-product extract 0.1%). Body weight gain was higher in +C and T3 for overall period than control and T1. Feed efficiency of were slightly improved in +C and T3 groups compared with that of control and T1. The small intestine weight tended to be higher in control and +C, but it's length showed high in only T1 group. Gizzard weight was significantly higher in T2 compared with other treatments(P<0.05). In contrast, spleen weight was significantly lower in control group(P<0.05), whereas the weight of cecum and liver were not significantly different by dietary treatment. Intestinal microflora was significantly lower or/and seemed to be low in softwood by-products treatment groups than control. Digestibility of energy and protein were statistically lower in control and T1 than other treatments(P<0.05). The IgG concentration of birds fed antibiotics, softwood by-product extract was higher than control and T1, but was no significance. The results of this experiments indicated that softwood by-product extract would be possible to apply for the feed additive in organic broiler diets.

In this study, the radioprotective effects of Grifola umbellata hot water extracts (Gu-extract) on mice were investigated. Single pre-administration of Gu-extract increased the 40-day survival ratio of irradiated mice from 65.5％ to 78.6％. The growth of 3 week old male mice in the irradiated group was slightly retarded as compared to those of the control and Gu-extract treated mice. The average spleen and thymus weights of the irradiated mice were lower than those of the control and Gu-extract treated mice. The weight reduction of testis in the irradiated mice was significant. While it was relatively slight in the Gu-extract treated mice as compared to that of control mice. No significant difference in the weight was observed in heart, kidney or liver among three groups. The leukocytes of the Gu-extract treated mice did not decrease dramatically as in the irradiated group, but recovery patterns were similar in both groups. Reduction of erythrocytes were similar in both groups but its recovery occurred more rapidly in the extract treated group. The glucose level of the Gu-extract treated group did not change during the period examined, while it was still higher in the irradiated group than the level in the control group in two weeks. The cholesterol levels in the irradiated and the Gu-extract treated groups were higher than that of control group on day 7, but decreased to the level of the control group on day 14. No difference was observed in total protein amount of the serum among the three groups. SDS-polyacrylamide gel electrophoresis of the soluble proteins extracted from various organs did not reveal differences to any extent in all groups except in the livers of the irradiated and extract treated groups, in which some proteins were missing or less present.
