The anesthetic effects by dosages of Tiletamlne-Zolazepam in the dogs were investigated and then the optimal dosages for the operation of patients were suggested. 1. In groups of T+Z 20, 10 and 5 mg/kg administration, anesthetic periods are 180~300, 33~47 and 40~50 minutes, respectively and complete recovery from anesthesia was shorted with taking 53~72 minutes in the group of 5 mg/kg administration. 2. Reflex responses to eyelids, cornea and pharyngolarynx were maintained but pedal reflexes became considerably sluggish 3. It showed tachycardias on ECG but there were no specific dysrhythmias. On EEG, it showed low voltage-fast waves before anesthesia, high voltage-fast waves in induction stage, low voltage-slow waves in anesthetic stage and high voltage-fast waves again in recovery stage. 4. Surgical procedures could be performed satisfactorily in 6 cases of the 10 mg/kg administration group, but in 3 of 5 cases of 5 mg/kg administration group it could be completed after additional administration. 5. In conclusion, it was considered desirable for anesthetizing dogs that for healthy cases T+Z at the level of 10 mg/kg B.W. was administered, and for poor risk patients, 5 mg/kg B.W., followed by an additional administration in unsatisfied cases.

Ixeris dentata was extracted with methanol and then the methanol extract was further fractionated to hexane, chloroform, ethyl acetate, butanol and aqueous fraction. The methanol extract of lxeris dentata had the strong antimutagenic effect on the aflatoxin B1(AFB1) and N-methyl-N'-nitro-N-nitrosoguanidine(MNNG) in Ames mutagenicity test and SOS chromotest. Among the solvent extracted fractions from the methanol extract, the chloroform fraction exhibited the greatest antimutagenic effect suppressing the mutagenicity of AFB1 with inhibition rate of 74 percent. The methanol extract of Ixeris dentata also revealed the inhibitory effect on the growth of MG-63 human osteosarcoma cells after 6 days of breeding at 37℃. The chloroform fraction and the ethyl acetate fraction from the methanol extract of lxeris dentata were most effective and inhibited the growth of MG-63 cells by 97 and 93 percent, respectively. It is suggested that the inhibitory effects of lxeris dentata on the mutagenicity and the growth of MG-63 human osteosarcoma cells are strong in the lipid soluble fractions.

The bark of Berberis koreana Palibin was fermented by Bifidobacterium longum B6 and Lactobacillus paracasei at $37^{\circ}C$ for 72 hour, then extracted by water solvent at $100^{\circ}C$ for 180 min. Total pholyphenol and flavonoid contents were improved by fermentation process, compared to conventional water extraction. The barks of B. koreana Palibin extracts by B. longum B6 (FE-B.L.) and by L. paracasei (FE-L.P.) showed 17% and 16% cytotoxicity on human normal cell lines(HEK293) at 1.0 mg/$m{\ell}$ of the highest concentration, respectively, which was about 3~5% lower than 20% from normal extracts (NE). DPPH radical scavenging activity of the FE-B.L. and FE-L.P. were about 73% and 75.9% higher than 56.8% of NE. The highest inhibitory potency on xathine oxidase and superoxide dismutase (SOD)-like activities were also measured as 31.9% and 61.9% by adding FE-L.P. of 1.0 mg/$m{\ell}$. On tyrosinase inhibition test, the FE-L.P. showed highest activity as 75.9% at 1.0 mg/$m{\ell}$. Generally, FE-L.P. showed higher antioxidant activities as well as higher tyrosinase inhibition activity, possibly due to high contents of total pholyphenol and flavonoid. In general, fermentation of barks of B. koreana Palibin has relatively better biological activities than normal extracts. Specifically, the extracts fermented by L. paracasei showed higher activities than that from B. longum B6.

Objectives : This study was carried out to investigate the effects of Soyumjungjang-tang(SJT) on the experimental ulcerative colitis induced by dextran sulfate sodium(DSS) in mice. Methods : Ulcerative colitis was induced through supplying 4% DSS solution as the drinking water for 7 days in 6-week-old male ICR mice. The colitic mice were divided into three groups: the sample groups were orally administered SJT in doses of 25mg/kg(S25 group) or 100mg/kg(S100 group) once a day for 10 days, from 3 days before starting drinking the DSS solution, and the control(C) group was administered normal saline instead of SJT. The DSS solution or SJT was not administered to the normal(N) group. The length of colon, histologic finding, the activities of myeloperoxidase(MPO) and alkaline phosphatase(AP), and the expressions of $IL-1{\beta}$, IL-6, COX-2, $NF-{\kappa}B$, and $I{\kappa}B$ in colonic mucosa was checked using immunoblot, ELISA, etc. The activities of chondroitinase, tryptophanase, ${\beta}-glucuronidase$ and ${\beta}-glucosidase$ in stool were also measured. Results : The length of colon shortened, histologic finding deteriorated, the activities of MPO, AP, chondroitinase, tryptophanase, ${\beta}-glucuronidase$ and ${\beta}-glucosidase$, and the expressions of $IL-1{\beta}$, IL-6, COX-2, $NF-{\kappa}B$ increased, and the expression of $I{\kappa}B$ decreased in the C group. All measures, except $NF-{\kappa}B$, were restored in S25 group, but some measures deteriorated more in the S100 group than in the C group. Conclusions : According to the above results, it is supposed that SJT has a potential therapeutic effect on ulcerative colitis.

Aging occurs as a part of maturation as the time progresses which manifests in the human body causing morphological and functional degeneration, eventually leading to death. This experimental study was conducted to investigate a herbal formula to fortify the heart with easy clinical applications. Sungshimsan was chosen to study its effects in heart lipid peroxide and metabolic enzyme system in senescence induced rats. After pre-treatment of Sungshimsan for 2 weeks at the dosage of A (100mg/kg), B (250mg/kg), C (350mg/kg), and D (500mg/kg), a lipid peroxide and metabolic enzyme system changes of the heart were meaured in 32 weeks old rats. The following results were obtained in this study: 1. The contents of lipid peroxide was significantly reduced in the experimental groups treated with greater than 2 weeks at 250mg/kg. 2. The enzymatic activity of cytochrome P-450, cytochrome b5, and NADPH-cytochrome P450 reductase were significantly decreased in the 250mg/kg, 350mg/kg, and 500mg/kg experimental groups. 3. The activity of glutathione and glutathione S-transferase were significantly increased in the 250mg/kg, 350mg/kg, and 500mg/kg experimental groups. 4. The activity of glutathione reductase and glutathione peroxidase were not influenced compared to the control group. 5. The activity of ${\gamma}$-glutamylcystein synthetase was significantly increased in the 250mg/kg, 350mg/kg, and 500mg/kg experimental groups. 6. The activity of enzymes detoxificatioon superoxide dismutase and catalase were not influenced compared to the control group. Summarizing above results suggest that the Sungshimsan has profound effects in the heart lipid peroxide, free radicals, and delaying the heart aging process. Further clinical researches and application can be anticipated on the topic of senility and gerontology.

In this study, the effects of the immune stimulator Euglena gracilis (Euglena) in cyclophosphamide (CCP)-induced immunocompromised mice were assessed. The key component β-1,3-glucan (paramylon) constitutes 50% of E. gracilis. Mice were orally administered Euglena powder (250 and 500 mg/kg body weight (B.W.)) or β-glucan powder (250 mg/kg B.W.) for 19 days. In a preliminary immunology experiment, ICR mice were intraperitoneally injected with 80 mg of CCP/kg B.W. during the final 3 consecutive days. In the main experiment, BALB/c mice were treated with CCP for the final 5 days. To evaluate the enhancing effects of Euglena on the immune system, mouse B.W., the spleen index, natural killer (NK) cell activity and mRNA expression in splenocytes lungs and livers were determined. To detect cytokine and receptor expression, splenocytes were treated with 5 ㎍/ml concanavalin A or 1 ㎍/ml lipopolysaccharide. The B.W. and spleen index were significantly increased and NK cell activity was slightly enhanced in all the experimental groups compared to the CCP-only group. In splenocytes, the gene expression levels of tumor necrosis factor-α, interferon-γ, interleukin (IL)-10, IL-6, and IL-12 receptor were increased in the E. gracilis and β-glucan groups compared to the CCP-only group, but there was no significant difference. Treatment with 500 mg of Euglena/kg B.W. significantly upregulated dectin-1 mRNA expression in the lung and liver compared to the CCP-only group. These results suggest that Euglena may enhance the immune system by strengthening innate immunity through immunosuppression.
