The effects of ginseng ethanol extract on the toxicity of lead acetate in mice were examined. Mice were given intraperitoneally daily doses of lead acetate 50mg/kg with ginseng ethanol extract 50mg/kg, 100mg and 200mg/kg for 3 weeks. The exposure of lead acetate showed the toxicity at all experimental assay such as the gain of body weight, the ratio of some organs weight to body weight, serum transaminase activity and creatinine value, hematocrit and WBC counts. These toxicities were inhibited significantly by the ginseng ethanol extract administration. The 50mg/kg and 100mg/kg administration of ginseng ethanol extract inhibited histopathological changes on kidney by lead acetate, whereas the 200mg/kg administration of the fraction enhanced histopathological changes.

Experiments were performed to investigate effects of ethanol and saccharin on the immune system in rats. 4% ethanol and 0.02, 0.20, 2.00% saccharin solution in 4% ethanol were provided ad libitum by tap water for 4 weeks. Rats were sensitized and challenged with sheep red blood cells(S-RBC). Immune responses were evaluated by relative immuno organ weight, antibody production, Arthus reaction, delayed type hypersensitivity, and rosette forming cell. Ethanol exposure decreased thymus weight and delayed type hypersensitivity. A combined solution of ethanol and saccharin decreased water intake, growth rate, spleen weight, thymus weight, humoral and cellular immune response. Especially, a 2% saccharin solution in 4% ethanol very significantly suppressed cellular immunity.

안영근,김정훈,이상근 환경독성보건학회 1990 환경독성보건학회지 Vol.5 No.3

Experiments were performed on mice to investigate the influences of cimetidine, ranitidine and famotidine on the immune response. Immune response were evaluated by antibody, Arthus reaction (Arthus), delayed type hypersensitivity (DTH), rosette forming cell (RFC), phagocyte activity and whit( blood cell (WBC) in mice, sensitized and challenged with sheep red blood cells (SRBC). The weight of liver, spleen and thymus were measured. Following results obtained in this experiment. 1) The administration of cimetidine as compared to normal group significantly decreased Arthus, Hemagglutinin titer (HA), RFC, DTH, WBC and phagocyte activity, but increased the activity of serum albumin. 2) The administration of ranitidine as compared to normal group decreased RFC and HA. 3) The administration of Famotidine as compared to normal group decreased DTH and RFC, and significantly decreased HA, Arthus and serum protein. 4) The administration of ranitidine and famotidine decreased more humoral immune response than cellular immune response, but the administration of cimetidine significantly decreased humoral and cellular immune response, WBC and phagocyte activity.

Amygdalin has been used for a long time as an anticancer agent. But because of its toxicity, it is difficult to administer continuously for treatment of cancer. This paper was attempted to reduce the side effect and toxicity of amygdalin. That is, effects of cysteine and streptomycin on the toxicity of amygdalin were investigated in rats orally administered amygdalin. 1. The group administered only amygdalin 400 mg/kg was effected on the lung and body weight, hematocrit, hemoglobin, clotting time, SGOT and albumin value. That is, lung and body weight, hematocrit hemoglobin and albumin value were significantly decreased. SGOT and clotting time were significantly increased compared with those of normal group. 2. Weight of lung was significantly increased in the C group (administred amygdalin 400 mg/kg and cysteine 300 mg/kg), D group (amygdalin 400 mg/kg and streptomycin 10 mg/kg), E group (amygdalin 400 mg/kg, streptomycin 10 mg/kg and cysteine 200 mg/kg)and F group (amygdalin 400 mg/kg, streptomycin 10 mg/kg and cysteine 300 mg/kg). 3. Values of hematocrit and hemoglobin were significantly increased, and clotting time was significantly decreased, in the E group and F group compared with those of A group. 4. SGOT was significantly decreased in the C group, E group and F group compared with that of A group. 5. The blood cyanide concentration was significantly decreased in the E group and F group compared with that fo A group. 6. In short, coadministration of cysteine and streptomycin are considered to reduce the toxicity of amygdalin in rats orally administered.

The effect of vitamin A on the immune response in ICR mice was studied. The effects were evaluated by immuno organ weight, peripheral circulating white blood cells, HA and HY titer, peritoneal exudate cells, RFC, Arthus reaction and DTH in mice. The spleen of mice was significantly hypertrophied by deficiency or over doses of vitamin A as compared with control group (50IU/㎏). Arthus reaction, RFC and peritoneal exudate cells were sharply decreased according to the increase of vitamin A doses. The number of white blood cell was decreased according to the increase of vitamin A doses, but in the case of vitamin A 50,000 IU/㎏ treated group, it was significantly increased. These results suggest that deficiency or over dose of vitamin A decrease ed humoral and cellular immune response.

The immunopotenciating effects of petroleum ether extract, ethanol extract and butanol fraction of panax ginseng on the immunotoxicity of Cimetidine were investigated in ICR mice. Immune responses were evaluated by antibody production, Arthus reaction, delayed type hypersensitivity (DTH), and rosette forming cell(RFC) in mice, sensitized and challenged with sheep red blood cells. To investigate the change of the non-specific immune responses, phagocyte activity and number of leukocytes in peripheral blood were measured also. The results of this study are summarized as followings; 1. Cimetidine treated group as compared with normal group generally decreased HA, 2-MER, RFC, number of circulating leukocytes and phagocyte activity whereas increased Arthus reaction and DTH. 2. The panax ginseng petroleum ether extract combined administration group as compared with the control group remarkably increased HA, 2-MER, number of circulating leukicytes and phagocyte activity. 3. The panax ginseng ethanol extract combined administration group as compared with the control group remarkably increased Arthus reaction, DTH, HA, RFC, number of circulating leukocytes and phagocyte activity. 4. The panax ginseng butanol fraction combined administration group as compared with the control group remarkably increased Arthus reaction, HA, 2-MER, RFC number of circulating leukocytes and phagocyte activity.

The purpose of this experiment was to investigate both the immunomodulatory effect of evening primrose(EP) oil and the effects of EP oil immunoregulation by cyclophosphamede in mice. EP oil at doses of 0.1, 0.2 and 0.4㎖/㎏ were orally administered to ICR male mice once daily for 28 consecutive days. Cyclophosphamide was injected intraperitoneally to ICR mice with a single dose of 5㎖/㎏ at 2 days before secondary immunization. Mice were sensitized and challenged with sheep red blood cells(S-RBC). Immnune responses were evaluated by humoral and cellular immune responses and non-specific immune response. The results of this study were summarzed as follows; (1) The humoral immune responses such as hemagglutination titer(HA). hemolysin titer(HY), Arthus reaction and plaque forming cell(PFC) were significantly enhanced in the low dose EP oil administered groups(0.1 and 0.2㎖/㎏). However, in the high dose EP oil administered group(0.4㎖/㎏) the responses were significantly lowered. (2) In the case of cellular immune responses, delayed type hypersensitivity reaction(DTH) was significantly decreased in EP oil whereas rosette forming cell(RFC) was remarkably enhanced. (3) Activities of natural killer cells and phagocyte were generally enhanced in EP oil. In addition, serum albumin and globulin were also increased.

마우스에 있어서 免疫反應에 미치는 마늘의 效果

黃永植,金正勳,安榮根 圓光大學校 1989 論文集 Vol.23 No.2

마늘이 아직도 世界倒處에서 많은 疾病의 治療 및 豫防의 目的으로 이용되고, 飮食의 향신료로서 마늘의 利用과 世界的 分布는 그의 人氣를 한층 더하여 주고 있다. 또한 健康專門分野에 從事하거나 硏究하는 사람들의 새로운 關心은 無毒내지 低毒性의 廣範圍 治療能을 갖는 物質이나 藥을 마늘로부터 探索하고저 하는데 집중되고 있다. 어떤 硏究報告는 많은 病原性眞菌과 細菌에 대하여 마늘推出物이 增殖沮止 또는 殺菌作用이 있다고 記述하였고, 最近의 動物實驗을 通한 硏究報告는 마늘의 高脂血症, 血液凝固, 動脈硬化症 및 低血壓 등에 대하여 有意性있는 保護作用이 있음을 밝힌 바 있다. 本 硏究의 結果 마늘이나 allicin은 體液性免疫에는 큰 影響이 없었으나 細胞性免疫은 顯著히 抑制하였고, 白血球數와 大食細胞의 活性에는 別로 影響이 없었으나 NK-cell의 活性은 그 量에 따라 增加시킴이 밝혀졌다. 이것이 抗癌作用의 動機가 된다고 思料된다. The immunomodulating and antitumor effect of raw garlic, boiled garlic and allicin were studied in mice. ICR male were divided into 10 groups and were fed on experimental diets for 4 weeks. Mice were evaluated for changes in immune status as measured by the antibody titer(HA) and hypersensitivity to sheep red blood cells(SRBC), organ weight, peripheral circulation white blood cell number, macrphage activity, and natural killer cell activity. Antitumor activity was measured by the inhibition rate of growth of Sarcoma 180. Increase of body weight was retarded, but liver weight was increased by raw garlic diets. However, spleen weight was increased by 2% boiled garlic diet and 0.002% allicin diet. Raw garlic and allicin diets suppressed the weight of thymus. Raw garlic and boiled garlic diets reduced Arthus reaction, and allicin diets reduced the delayed type hypersensitivity. HA titer and peripheral circulating white blood cell number were not affected by all experimental diets. Macrophage activities were increased by 1% raw garlic diet and 0.003% allicin diet administration. Growth rates of Sarcoma 180 were inhibited by all experimental diets administration. Especially, boiled garlic diets and allicin diets inhibited the growth of tumor. Natural killer(NK) cell activities were increased by 3% boiled garlic diet and 0.002% allicin diet administration. The data show that raw galic, boiled garlic and allicin treatment altered humoral and cell-mediated immunity. Increased NK cell activity may account for the increased resistance to challenge with tumor cells.
