Objectives : The aim of this study was to investigate the immunopotentiating activity of combine extract that Silkworm and Cinnamomum cassia. Recently, acute epidemic diseases such as cold and viral respiratory diseases have been emerging. So, interested in immunity enhancement has been increasing, and research on natural products to promote immunity activity has been actively conducted. Methods : To confirm the immunopotentiating activity effect, Silkworm (SW), Cinnamomum cassia (CC), and SWCC combined extracts were treated 14 days at 300 mg/kg/day. The changes of glutamic oxalacetic transaminase (GOT), glutamic pyruvate transaminase (GPT) in serum were analyzed after experiment. The changes in the total spleen cell number were measured. Immune cells in spleen were analyzed using fluorescence activated cell sorter (FACS). also, analyzed the expression of cytokines in spleen. Results : Total number of cells in the spleen and FACS analysis of T lymphocytes activated in the spleen showed that the SWCC combined treated group had much higher frequency of active cells than both single groups. The ratio of CD4+CD8+, CD4+CD69+ and CD4+CD25+ T cells in spleen, SWCC is higher than other groups except Nor in CD4+, CD4+CD69+, CD4+CD25+ T cells. The results of this study suggest that SWCC can help immune function via IL-2, IL-10, IL-12, IFN-${\gamma}$ cytokine production, increased T lymphocytes and splenocyte proliferation. Conclusion : Therefore, these results suggested that the SWCC combined extracts administration increase stronger immunity enhancement than when SW and CC adminstration.

Objectives : Although the pharmacological effects of anti-inflammatory and antioxidant action of Atractylodes macrocephala Koidzumi water extract (AM) have been proven from many studies, reports on the antioxidant effect of AM on ulcerative colitis (UC) are scarce. Therefore, we aimed at evaluating the anti-oxidant effect of AM on the DSS-induced UC model. Methods : To induce ulcerative colitis, 8-week-old male Balb/c mice received 5% DSS in drinking water for 1 week. After 1 week of adaptation, mice were divided into four groups (n=8 each) for use as normal (Normal), DSS Control (Control), DSS + AM 100 mg/kg (AM100)-treatment, DSS + AM 200 mg/kg (AM200)-treatment. After 1 week of the experiment, the animals were sacrificed, and the extracted colon tissue was analyzed for protein through western blot. Results : As a result of confirming the macroscopic changes in colon tissues to confirm the therapeutic effects of AM, the decrease in colon length was suppressed in the AM treatment group compared to the control group. In addition, as a result of biochemical analysis, AM administration significantly reduced serum glutamic oxalacetic transaminase, glutamic pyruvate transaminase levels and tissue malondialdehyde levels. As a result of confirming the protein expression level through western blot, AM administration significantly decreased the expression of NADPH-related proteins such as NOX2, p22^phox, and iNOS, but significantly increased the expression of SOD, catalase, and GPx-1/2. Conclusions : AM may improve DSS-induced UC in mice by modulating NADPH and antioxidant-related proteins. In conclusion, AM showed an antioxidant effect through the improvement of oxidative stress on UC.

The purpose of this paper is to find out whether Du-chung tea and Du-chung tea added with Stevia leaves are suitable for everyday use of diabetics. For this purpose, states of diabetic rabbit, induced by giving alloxan to normal rabbit, were examined in two cases. One was to administer Du-chung tea sweetened by sugar to the above same animal and the other to apply Du-chung tea sweetened by Stevia leaves, instead of sugar, under the equal condition. A study was carried out to determine the effects on blood sugar level, contents of BUN (blood urea nitrogen) and total cholesterol, and GPT (glutamic pyruvate transaminase) activity in both groups. The following results were obtained. 1) Sweetness of Du-chung tea added with 0.3-0.5% Stevia leaves was never to the standard sweetness. 2) Sweetness of Du-chung tea with 2% sugar plus 0.2% Stevia leaves was the nearest to the standard sweetness. 3) Du-chung tea with 0.5% Stevia leaves was recognized as the most effective the next was Du-chung tea no sweetening, and the worst was Du-chung tea with sugar. Addition of 0.2% Stevia leaves without lessening sugar concentration of the above Du-chung tea showed the same result as Du-chung tea with sugar. 4) Du-chung tea with Stevia leaves and Du-chung tea without sweetening had the tendency of reducing the total cholesterol content in serum, while only Du-chung tea with Stevia leaves presented remarked difference after 4, 6 and 10 days, when they were compared with control group. 5) Degree of CPT, activity had in general the similar tendency- to that of total cholesterol content. 6) Taken Du-chung tea with Stevia leaves and Du-chung tea without sweetening, the BUN content showed reducing tendency in small quanity, but, having little defference from control group.

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.

The purpose of this study was to investigate the effect of vitamin E and selenium on the antioxidative defense mechanism in the liver of streptozotocin(STZ)-induced diabetic rats. Sprague-Dawley male rats(120$\pm$10gm) were randomly assigned to one control and five STZ-diabetic groups. Diabetic groups were classified to STZ-0E (vitamin E free diet), STZ-40E(40mg vitamin E/kg of diet), STZ-400E(400mg vitamin E/kg of diet), STZ-S(0.5ppm Se/kg of diet) and STZ-400ES(400mg vitamin E and 0.5ppm Se/kg of diet) according to the level of vitamin E and selenium supplementation. Diabetes was experimentally induced by intravenous adminstration of 55mg/kg of STZ in citrate buffer(pH 4.3) after 4-weeks feedng of six experimental diets. Animals were sacrificed at the 4th day of diabetic states. Activities of the serum glutamic oxaloacetate transaminase(GOT) and the glutaminc pyruvate transaminase(GPT) in STZ-0E, STZ-40E and STZ-S rats were higher than those of control. Liver xanthine oxidase activities were similar to serum GOT and GPT. Liver superoxide dismutase(SOD) activities were higher in STZ-0E and STZ-40E groups by 33%, 22%, respectively than that of control. Glutathione S-transferase(GST) activities of liver were similar to GSH-Px activities. The contents of vitamin E in liver tissue were significantly lower STZ-0E, STZ-40E and STZ-S groups by 50%, 36%, 45% than that of control. Reduced glutathione(GSH) contents of liver were lower STZ-0E, STZ-40E, STZ-400E, STZ-S and STZ-400ES groups by 57%, 51%, 19%, 18%, 12% than that of control. Lipid peroxide values (LPO) in liver were higher 5.6, 2.3 and 2.3 times in STZ-0E, STZ-40E and STZ-S group than that of control. The present results indicate that STZ-induced diabetic rats are more sensitive to oxidative stress, leading to the acceleration of lipid peroxidation process, which can be more accelerated by feeding the low level of dietary vitamin E. In the coincident supplementation of high dietary vitamin E and selenium antioxidative enzymes activities and physiolosical antioxidants were increased more than those of the separate supplementation of vitamin E or selenium. Therefore, dietary vitamin E and selenium reduced peroxidative damage of tissue, promoting antioxidative defense mechanism against lipid peroxidation by diabetes.

Objectives : We have studied to know analgesic effects of the combination of Aconitum Cilliare Tuber with honey in the models of peripheral neuropathic pain. Methods : Neuropathic pain model was made by ligating left 5th lumbar spinal nerve. After 3 days, combination of Aconitum Ciliare Tuber and honey extract was administrated each alternate day. Administration was divided three groups, that is NP-OA1(0.06 mg/ml), NP-OA2(0.24 mg/ml), and NO-OA3(0.96 mg/ml). After that, we examined the withdrawl response of neuropathic rats legs by von Frey filament and acetone stimulation. And also we examined c-Fos, glutamic oxaloacetic transaminase(GOT), glutamate-pyruvate transaminase(GPT) and change of weight. Results : Mechanical allodynia in NP-OA1 groups were significantly decreased compared with the control group. Cold allodynia in all experimental groups were no significant differences with the control group. c-Fos protein expression on the central grey, all experimental groups were lower than that of control groups. But, there were no statistically significant differences. Change of weight in all experimental groups were significantly increased compare with the control group. In blood serum GOT in NP-OA1, NP-OA2 groups were significantly decreased compare with the control group. In blood serum GPT in all experimental groups were no significant difference with the control group. Conclusions : We had noticed that the combination of Aconitum Ciliare Tuber and honey decreased mechanical allodynia in the model of neuropathic pain compared with the control group and it has not efficacy in elevation of GOT, GPT and weight loss etc., the element of which becomes damage to liver. This study can be proposed that Aconitum Ciliare with Honey may be applicable to neuropathic pain in clinic. But it is reliability not that cold allodynia and c-Fos expression have effectively to control pain. Therefore we have to follow up about that.
