  • The comparison of topic effects of methanol and ethanol on rats and frogs was performed. Intraperitoneal administration in graded doses of absolute alcohols showed specific toxicities on animals, suggesting that these substances had different effects on species specificity of animals. Throughout the experiment, the following results were obtained and summerized here. 1. In rats $LD_{50}$ dose of absolute methanol was $2.65{\mu}l/g$ of body weight, while that of absolute ethanol was $1.85{\mu}l/g$ of body weight. 2. The $LD_{50}$ dose of methanol in frogs was $17.2{\mu}l/g$ of body weight, while that of ethanol was $10.9{\mu}l/g$ of body weight.

  • Pharmacological studies on the water extracts of Sambbcus latipnna var. coreana have confirmed that there are: 1) Remarkable sedative actions in preteated mice with C.N.B (caffeine and sodium benzoate) by the administration of intraperitoneal injection. 2) Antihypertensive actions in rabbits intraperitoneally injected with the extract, and as antihypertensive components, rutin, and crystal A (m.p. $250{\sim}254^{\circ}$, Liberman-Buchard's reaction, positive) were isolated from Sambucus latipinna var. coreana. 3) Marked diuretic actions in mice intramuscular injection with the dose of 600mg/kg.

  • The effects of antimetabolite, 6-aminonicotinamide (6-AN), on ultrastrudural changes in the spinal cord of golden hamster were investigated. Intraperitoneal administration of 6-AN (10 mg/kg body weight) every two days gave rise to a marked reduction of about $30\sim40%$ in body weight after $26\sim28$ days ($13\sim14th$ injection). In the lesions of the spinal cord, neuroglial cells such as astrocytes and oligodendrocytes were severely damaged, but neurons and blood vessels were not affected by 6-AN. The myelin sheath was also affected by 6-AN. Vacuoles observed in the lesions were produced by the swelling and degenerating changes of neuropils and neuroglial cells. Numerous swollen mitochondria and cisterns of rough endoplasmic reticulum were observed in the watery cytoplasm of damaged neuroglial cells, but intermediate filaments were well preserved. Especially in the damaged astrocytes, the outer nuclear membrane were partially swollen and formed a halfmoonlike structure. It is suggested that as well as the multivesicular bodies protruding from the swollen dendrites, the conjugation of adjacent vacuoles also participated in the formation of large vacuoles.

  • As previously reported, an immunoglobulin M (IgM) monoclonal antibody (MAb) B6.1, specific for a cell wall B-l,2-mannotriose, was protective against vaginal infection due to Candida albicans when mice were treated with the antibody. In this study, the role of neutrophil was examined in the protective effect of MAb B6.1 against vaginal infection. To deplete neutrophils, mice were given intravenously rat anti-mouse neutrophile MAb RB6-8C5 prior to intraperitoneal administration of MAb B6.1 to these mice. The mice were examined for antibody in their reproductive tract. By an ELISA, MAb B6.1 was found in the vaginal homogenates, but no antibody was detected in vaginal lavage materials. The neutropenia was induced by a single dose of the anti-neutrophil antibody, but lymphocytes were also partially depleted. The protective effect of MAb B6.1 was decreased when mice pretreated with MAb RB6-8C5 were given the anti-Candida antibody before challenge with C. albicans yeast cells intravaginally. These results show that neutrophils are involved in the MAb B6.1 protection against Candida vaginal infection.

  • The aqueous extract of Siegesbeckia pubescens (SPAE) inhibited compound 48/80-induced systemic anaphylaxis 100% with the dose of 1.0, 0.5 mg/g body weight (BW) at 1 h before or 5 min, 10 min after intraperitoneal injection of compound 48/80. The passive cutaneous anaphylaxis (PCA) reaction also inhibited to 78.5% by oral administration of SPAE(1.0 mg/g BW). When SPAE pretreated on mice at concentrations ranging from 0.0001 to 1.0 mg/g BW, the serum histamine levels were reduced in a dose-dependent manner. Moreover, SPAE ($100-800{\mu}g/ml) dose-dependently inhibited the histamine release from peritoneal mast cells (RPMC) by compound 48/80 $(5{\mu}g/ml)$. Analysis by microscopic appearance observation revealed that SPAE $(500{\mu}g/ml) stabilized the RPMC membrane. Therefore, these findings indicate that SPAE inhibits anaphylactic reactions through stabilization of mast cell membrane.

  • The present investigation was under taken to study whether the tumor-associated macrophages (TAM) of Daltons lymphoma (DL), a spontaneous transplantable murine T cell lymphoma can be activated to tumoricidal state by crude thymus extract. Intraperitoneal administration of thymus extract to DL-bearing mice resulted in activation of TAM with an enhanced IL-1, TNF and antigen presenting ability. It was found that treatment with thymus extract could also enhance the phagocytic and cytotoxic activity of TAM. However, only a marginal increase in arginase activity was observed. Till date to the best of our knowledge the effect of crude thymus extract on the activation of tumor associated macrophages has not been investigated, this study provides a new piece of information in the area of thymus therapy.

  • In order to study the antioxidative action of the effectient garlic components, peroxidase and superoxide dismutase activity were compared through the in vitro and in vivo experiments. RESULTS : 1. Observing the effects on peroxidase activity of efficient components in vitro, garlic oil, alliin and ethanol fraction showed effective, which was similar to the trend of TBA value, peroxide value and induction time for the first period of lipoperoxide formation in vitro. 2. In vivo experiment with peroxidase activity, the ethanol fraction and garlic oil were effective when intraperitoneally administered as well as orally administered. 3. Considering the superoxide disutase activity in vitro, the garlic oil, alliin and ethanol fraction were effective in efficient components. But non-kaolin fraction inhibited the activity on the contrary. 4. In terms of the efefcts on superoxide dismutase activity in vivo, alliin and garlic oil wee effective in intraperitoneal adminstraton and the ethanol fraction and alliin in oral administration.

  • This study was carried out to investigate effects of Cuscutae semen extract(C. S. E) on $CCI_4$-induced liver damage in rabbits and acute toxicity in mice. $LD_{50}(mg/kg)$ of C. S. E. was 7.83g/kg by intraperitoneal administration in mice. C. S. E. groups were showed more rapid recuperation than the control group intoxicated by $CCI_4$ only. SGPT activity was lowered significantly in 800mg/kg after 6 days. The levels of total cholesterol and total bilirubin and alkaline phosphatase were decreased apparently in 800mg/kg from 6 days. It is suggested that C. S. E. can be administered not only as a therapeutic agent(such as liver tonics) but also a healthy food to shorten the recovery time in liver diseases.

  • 본 연구에서는 저령(Grifola umbellata)의 균핵을 끓여 추출물을 얻어 이것이 실험용 생쥐에 미치는 영향을 조사하였다. 생쥐에 저령 열수 추출물(100 mg/kg 체중)을 1일 1회 2일간 복강투여 했을 때 암 발생의 원인이 될 수 있는 superoxide radical의 생성은 대조군에 비해 약 22% 가량 억제되었으나, 지방과산화는 대조군과 별다른 차이를 보이지 않았다. 반면에 항피로능은 대조군에 비해 추출물 투여군의 유영기간이 약 1.8배 가량 증가되어 저령의 열수 추출물에 항피로 효과성분이 있음을 알 수 있었다.

  • Single dose of Hantabax, HFRS-vaccine, was given to both sexes of Sprague-Dawley rats and ICR mice, subcutaneously and intraperitoneally. Any toxic symptom was not noted in the treated animals. Macroscopic examination on the organs of tested animals showed no abnormal findings. In general toxicological aspects Hantabax was practically nontoxic in rats and mice upto a single dose of 1000 times of human clinical dose equivalent via subcutaneous and intraperitoneal administration.
