In order to investigate the protective effects of Jiyusaenggan-Tang by F-I(Jiyusaenggan-Tang aspirated by distilled water), F-II(Non-polysaccharides in Jiyusaenggan-Tang) and F-III(Polysaccharides in Jiyusaenggan-Tang), experimental studies were performed in mice with liver injury induced by $CCI_4$, and d-galactosamine. The results were summarized as follows : 1. The increases of the serum GOT activities in mice induced by $CCI_4$ were inhibited significantly by the administration of highly concentrated FIII. The increases of the serum GPT, LDH, and ALP activities in mice induced by $CCI_4$ were inhibited significantly by the administration of highly concentrated FI and FIII. 2. The increases of the serum total-cholesterol and triglyceride activities in mice induced by $CCI_4$ were inhibited significantly by the administration of highly concentrated FI, FII and FIII. 3. On liver injury induced by the $CCI_4$, the activities of GOT, GPT, ALP, LDH were inhibited by highly concentrated FIII, F-I, F-II, and F-I, F-II, F-III on total cholesterol level and F-III, F-I, F-II on triglyceride level in order of their efficacies. And F-III is considered to be the most effective component. 4. The increases of the serum GOT, GPT activities in mice induced by d-galactosamine were inhibited significantly by the administration of FI and FIII. The increases of the serum LDH, ALP activities in mice induced by d-galactosamine were inhibited significantly by the administration of FI and FIII. 5. The increases of the serum Total-cholesterol, Triglyceride activities in mice induced by d-galactosamine were inhibited significantly by the administration of FI, FII and FIII. 6. The increases of the serum GOT, GPT activities in mice induced by d-galactosamine were inhibited significantly in F-III administrated group and then F-I in order of efficacies. FII does not showed significant effect, on inhibiting the activities of serum GOT and GPT levels. The activity of ALP was inhibited by F-III, F-I, F-II, LDH by F-III, F-I in order of efficacies, and F-II did not showed significant effect on LDH activity. The triglyceride level was decreased significantly by F-III, F-II, F-I and the total cholesterol level by F-II, F-I, F-III in order of their efficacies. Judging from the above results, it is considered that Jiyusaenggan-Tang has protective effect against liver injury, and that Polysaccharides in Jiyusaenggan-Tang is more effective.

After infection of male mice with the plerocercoids (spargana) of Spirometra mansoni, serum levels of estrogen and testicular weight were analyzed by enzyme-linked immunosorbent assay (ELISA) and weighing machine, respectively. The serum level of estrogen increased progressively in infected mice compared with normal controls, whereas the testicular weight of infected mice decreased significantly (P < 0.05). These results suggest that certain substances from spargana change the steroid hormone metabolisms in the host by unknown pathways, and chronic infection may contribute to change of the function of steroid hormone target organ, i.e., testis, in male mice.

This study was carried out to investigate the effect of Lentinus edodes which were harvested at different times of maturity on blood glucose and lipid levels in diabetic mice. The diabetic KK mice were fed diets supplemented with Lentinus edodes harvested early (LE) or late (LL) for eight weeks, and control (CO) mice were fed regular diet without Lentinus edodes. Diet intake, body weight, organ weight, blood glucose and serum lipid levels were measured. The mice which were fed diets supplemented with LE and LL showed significantly lower body weights compared to the CO group. There were no significant differences in the diet intake and the weights of different organs including liver, heart, kidneys, and epididymal fat pad among three different groups. Furthermore, the concentrations of serum triglycerides and total cholesterol were significantly lower in LE and LL groups compared to the CO group. These results clearly demonstrate that Lentinus edodes, regardless of their harvested period reduced body weight and serum lipid without affecting blood glucose level in diabetic mice.

Mullerian inhibiting substance (MIS) is a member of the TGF-${\beta}$ (transforming growth factor-${\beta}$) family whose members play key roles in development, suppression of tumour growth, and feedback control of the pituitary-gonadal hormone axis. MIS is expressed in a highly tissue-specific manner in which it is restricted to male Sertoli cells and female granulose cells. The serum levels of MIS in prenatal and postnatal ICR mice were measured using the enzyme-linked immuno-solvent assay (ELISA) using the MIS/AMH antibody. Mice were grouped by age: the significant periods were at the onset of development. During sex organ differentiation, no remarkable difference between female and male foetus MIS serum levels (both<0.1 ng/ml) was observed. However, MIS serum levels in pregnant mice markedly changed (4.5~12.2 ng/ml). After birth, postnatal female and male mice serum MIS levels changed considerably (male: <0.1~138.5 ng/ml, female: 5.3~103.4 ng/ml), and the changing phase were diametrically opposed (male: decreasing, female: fluctuating). These findings suggest that MIS may have strong associations with not only develop-ment but also puberty. For further studies, establishing the standard MIS serum levels is of importance. Our study provides the basic information for the study of MIS interactions with reproductive organ disability, cancer, and the effect of other hormone or menopause. We hypothesise that if MIS is regularly injected into middle-age women, meno-pause will be delayed. We detected that serum MIS concentration curves change with age. The changing phase is different between males and females, and this difference is significant after birth. Moreover, MIS mRNA is expressed during the developmental period (prenatal) and also in the postnatal period. This finding indicates that MIS may play a significant role in the developmental stage and in growth after birth.

Acute and subacute toxicity of Artemisia asistica Nakai Aqua-acupuncture Solution (ANAS) were studied in ICR mice. In acute toxicity test, mice were injected intraperitoneally with single dose of $1{\times}$, $5{\times}$, $10{\times}$ ANAS, and toxicological responeses were observed for consecutive 14 days. Mortality, body weight changes, organ weight, and serum chemistry were performed. The mortality and body weight changes of mice treated with $1{\times}$ and $5{\times}$ ANAS were not affected during the experimental periods. With the $10{\times}$ ANAS treatment, there were dead animals and changes of body weight, organ weight and serum biochemical values were observed during the experimental period. In subacute toxicity test, mice were injected intraperitoneally with doses of $1{\times}$, $10{\times}$ ANAS for 14 days. No difference was found between control and $1{\times}$ ANAS treated group in mortality, changes of body weight and organ weight, and serum biochemical values. However, Dead animals, changes of body weight and organ weight, and increased serum biochemical values were observed with $10{\times}$ ANAS treated groups. These results suggest that $1{\times}$ ANAS causes no toxicity in acute and subacute toxicity tests. However $10{\times}$ ANAS causes toxicity in both tests.

Effect of the butanol fraction of Astragali Radix (BFAR) on the humoral immune response were investigated in ICR mice. Mice were divided into 4 groups and BFAR at doses of 5,25 and 125 mg/kg were administered orally to mice daily for 3 weeks, and the normal animals were given vehicle. The results of this study are summarized as follows; the relative weight of spleen was markedly increased by BFAR treatment, compared with that in normal mice. However, the body weight gain and the relative weight of liver were not affected. Splenic plaque forming cells and hemagglutination titers to sheep red blood cells, and the secondary IgG antibody response to bovine serum albumin were also dose-dependently enhanced by BFAR treatment. In these mice, BFAR did not increase serum alanine aminotransferase total protein, sect albumin and albumin/globulin ratio when compared with those in normal mice. Thus, these findings indicate that BFAR significantly enhances humoral immune response to antigen in concentrations that do not affected liver function.

Objectives : The aim of this study was to know the immunity reponse of Esubwhaltong-tang(hereafter referred to ESWTT) to rheumatoid arthrits in CIA(collagen induced arthritis) mice. Methods : For this purpose, ESWTT was orally administerd to mice with arthritis induced by collagen II and then value of immunocyte in paw joint, cytokine(IL-6, $TNF-{\alpha}$), rheumatoid factor(IgG and IgM) and collagen II specific antibody in the serum were measured. Results : 1. The cytotoxicity was not shown on hFLSs and liver. 2. Marginal erosion, necrotic chodrocytes, cartilage and bone degradation were improved in histological section of paw joints from CIA mice(ESWTT extract administration group). 3. Total cell number of paw joint in CIA mice(ESWTT extract administration group) was decreased significantly. 4. The absolute number of CD3+, CD3+/CD69+, CD4+, CD4+/CD25+, CD49b+, CD3+/CD49b+ cells in CIA mice(ESWTT extract administration group) were decreased significantly. 5. The levels of IL-6 and $TNF-{\alpha}$ in the serum of CIA mice(ESWTT extract administration group) were decreased significantly. 6. The levels of total IgG and IgM in the serum of CIA mice(ESWTT extract administration group) were decreased significantly. 7. The level of collagen II specific antibody in the serum of CIA mice(ESWTT extract administration group) was decreased significantly. Conclusions : Comparison of the results for this study showed that ESWTT had immunomodulatory effects of suppressing. So we expect that ESWTT could be used as an effective drugs for not only rheumatoid arthritis but also auto-immune disease.

The insecticide p-nitropheny diethyl thiophospate is alse known by the symbol E.605 and a legion of trade names including “parathion”. The insecticide is widely used in agriculture, but it is highly toxic and now clear that parathion behaves like a cholinergic drug by inhibiting the enzyme cholinesterase. In order to know acute toxicity and the changes of glucose concentrations and activity according to time lapsed in female mice given orally single with the half dose to $LD_{50}$ of parathion, glucose contents and cholinesterase activities in serum as well as cholinesterase activities in whole brain and spinal cord were investigated, otherwise median lethal dose ($LD_{50}$) of parathion given orally against female mice was determined. The results obtained were summerized as follows ; 1. $LD_{50}$ value of parathion given orally to female mice was 7.1mg/kg(95% confidence limits, 3.8-13.1mg/kg) 2. The inhibition rate of cholinesterase activities in serum of parathion-administrated mice according to time lapsed were peakly decreased to 61% after 30 minutes in comparison to control group, but activities were completely recovered after 48 hours. 3. The inhibition rate of cholinesterase activities in whole brain of parathion-administrated mice according to time lapsed were peakly decreased to 49% after 2 hours in completely recovered after 24 hours. 4. The inhibition rate of cholinesterase activities in spinal cord of parathion-administrated mice according to time lapsed were peakly decreased to 57% after 2 hours in comparison to control group, but activities were completely recovered after 48 hours. 5. The changes of glucose contents in serum of parathion-administrated mice according to time lapsed and in directly after death due to parathion poisoning were no significantly difference.

Cancer cachexia, characterized by weight loss and progressive tissue wasting, has been postulated to be mediated by cytokines. This study was conducted to evaluate the effect of Korean Traditional Medicine (KTM ; mokhyang, jisil, osooyu) mixture on food intake, blood cytokines level and blood nutrients status of the cachexia induced-mice. Thirty male Balb/c mice aged 6-8 weets were blocked into 3 groups that were Normal (no colon26 cells) Control (colon 26 cells) and KTM (colon26 cells + KTM extract mixture) group. In Control and KTM groups, murine adenocarcinoma colon 26 cells were injected subcutaneously to induce cachexia. KTM mice were given 200 ul KTM extract mixture (7%) per day. Half of each groups were sacrificed at the 14 th day to see serum cytokines & nutrients and the others were fed until almost of control group died to see life span. food intake and body weight were decreased significantly in cachexia induced groups. Tumor weight of KTM group was significantly lower than control group. Serum cytokines (IL-1$\beta$ and TNF-$\alpha$) level of cachexia induced groups were increased than those of normal group, and those of KTM group were significantly lower than the level of control group. Total serum protein and serum albumin were higher in KTM group than other groups. TG and fatty acid were lower in cachexia induced groups than normal group. HDL-cholesterol in serum was increased in KTM group. Effect of oral administration of KTM extract mixture on survival time of colon26 bearing mice showed extension of the life span. Overall, this study showed that KTM (mokhyang, jisil, osooyu) extract mixture inhibited the growth of cancer cell, changed the secretion of cytokines induced by colon26 adenocarcinoma in mice, and changed nutrition metabolism.

Berberine, a protoberberine isoquinoline alkaloid, showed inhibitory effects on dopamine content in PC12 cells $(53.8\%\;inhibition\;at\;20\;{\mu}M)$. Tyrosine hydroxylase, the rate-limiting enzyme in the catecholamine biosynthetic pathway, was inhibited at $20\;{\mu}M)$ of berberine by $21.8\%$ relative to control. Thus, we hypothesized that the inhibition of tyrosine hydroxylase by berberine might be partially contributed to the decrease in dopamine content in PC12 cells. Furthermore, we investigated the effects of berberine on catecholamine content of serum after immobilization and cold stress in mice. Adult male mice were either subjected to 30 min of restraint or to 2 hr of cold chamber at $4-6^{\circ}C$. Serum norepinephrine, 16.8 pmol/ml, in control mice was increased to 28.8 pmol/ml by immobilization and the stress-induced rise in serum norepinephrine was partially blocked by the treatment of berberine (10 mg/kg, i.p.) once a day for 6 days. Berberine (10 mg/kg/day for 3 days, i.p.) also inhibited the increase in serum norepinephrine by cold stress in mice. These results suggest that berberine may be developed as the promising antistress agent.
