  • The polysaccharide fraction from the rhizome of Trichosanthes kirilowii (Cu-curbitaceae) showed marked antitumor and cytotoxic activity with immunopotentiating activity. It was evidenced by the increase in the number of circulating leucocytes and peritoneal exudate cells and the recovery of lowered antibody forming activity in mice. The polysaccharide was mainly composed of glucose, galactose, fructose, manmose and xylose and a small amount of protein.

  • In order to investigate the effects of YOOKMIJIHWANGTANG, GAMIJIHWANGTANG and PALMIJIHWANGTANG on the various immune responses, the chemotactic, adherent, nitric oxide release ability of macrophages were studied in vivo and in vitro. The results obtained were follows : 1. The total number of peritoneal exudate cells from mice injected with three drugs were 2~3 times more than those from the PBS. 2. The administration of three drugs enhanced significantly the Fc receptor mediated activity(phagocytosis, rosette formation activity). 3. The administration of three drugs enhanced significantly the chemotactic activity of peritoneal macrophages. 4. The administration of three drugs enhanced significantly the adherent activity of macrophages and neutrophils. 5. The administration of GAMIJIHWANGTANG and PALMIJIHWANGTANG enhanced significantly the chemotatic activity of macrophages (p<0.01). And also the administration of YOOKMIJIHWANGTANG enhanced significantly the chemotatic activity of macrophages(p<0.05). 6. The administration of GAMIJIHWANGTANG and enhanced significantly the chemotatic activity of neutrophils(p<0.01). And also the administration of YOOKMIJIHWANGTANG and PALMIJIHWANGTANG enhanced significantly the chemotatic activity of neutrophils(p<0.05). From above findings, it is suggested that YOOKMIJDTWANGTANG, GAMIJIHWANGTANG and PALMIJIHWANGTANG seems to produce the increase of immune response such as the Fc receptor activity, chemotactic activity, adherent activity, nitrate release of macrophages. From the above results, the GAMIJIHWANGTANG among three drugs may be the most useful drug having immunostimulating effects.

  • 간흡충 피낭유충의 경구감염 또는 간흡충 성충의 대사산물의 피내주사로 감작한 근교계 nude 및 DS 마우스의 복강삼출세포와 혈청이 간흡충 감염에 대한 면역을 동승(syngeneic) 마우스에 이입하는지 여부를 구명하기 위해 대조군 마우스에서의 EpG, 부하충체수 및 모장당 plaque 형성세포수를 기준으로 감작군에서의 그 성적과 비교하였다. Challenge 감염후 EpG의 변동은 감작군과 비감작 대조군 마우스와 nude 및 DS 마우스와의 사이에 유의한 차를 인정할 수 없었다. 간흡충 성충의 회수률에서는 감작군과 비감작 대조군 사이에 유의적 차를 인정할 수 없었으나 nude 마우스는 DS 마우스에 비하여 다소 높은 회수률을 나타내었다. 비장에서 plaque 형성세포는 복강 삼출세포 $5{\times}10^5$와 Group II DS 마우스의 혈청 0.1 ml를 복강에 감작한 제4군에서만 소수 검출할 수 있었다. 이상의 성적으로 미루어 보아 세포성 면역계에 결손이 있다고 알려진 근교계 nude 및 DS의 복강삼출세포와 혈청에 의해서는 간흡충에 대한 면역이 이전되지 않음을 확인하였다.

  • H. erinaceum은 현재 산업적으로 매우 주목되고 있는 기능성 소재들 중의 하나이다. 본 연구에서는 식용은 물론 각종 약리효과를 나타내는 H. erinaceum의 기능성 식품의 제품화 연구 일환으로, 지금까지 체계적으로 연구된 바 없는 H. erinaceum의 액체배양을 시도하고, 생성된 균사체의 생리기능성의 변화를 자실체의 물 추출물과 비교, 조사함으로써 H. erinaceum 액체배양 생성물의 생리기능 효과를 평가, 규명하고자 하였다. H. erinaceum의 자실체 및 균사체 물 추출물은 HeLa (human cervix epitheloid carcinoma; 인간 자궁 상피암세포), Raw264.7 (mouse monocyte macrophage; 생쥐 단핵 대식세포), Jurkat (human acute T cell leukemia, 인간 급성 T 백혈병 세포), KATO3 (human gastric carcinoma 인간 위장 암세포), EL4 (mouse T lymphoma 생쥐 T 림프종 세포), LyD9 (mouse bone marrow plurypotent stem cell; 생쥐 공수유래 간세포) 등 각종 암세포주에 대해 농도 의존적으로 증식 억제 효과를 나타내었다. 자실체 추출물은 균사체 추출물보다 대부분의 암세포 증식의 억제 효과가 컸으며, 가장 높은 암세포 증식 억제효과를 보인 자실체 열수 추출물의 효과는 Raw 264.7 및 EL4 세포주를 사용한 Taxol와의 비교실험 결과, 자실체 농도 0.01$\sim$10 mg/ml에서 자실체 사용량의 1/1000에 상당하는 양의 Taxol 효과와 비슷하였다. 자실체 및 균사체 열수 추출물들은 1 mg/ml 농도에서 복강세포의 nitric oxide 생산 유도능을 나타내었으며, lipopolysaccharides 자극으로 더욱 증가하였다. 반면, 비장세포의 증식유도능 및 interleukin-2 유도능에서는 각 시료 단독으로는 증식 유도 및 interleukin-2 유도능을 나타내지 않았으나 각각 lipopolysaccharide와 concanavalin A의 첨가 및 concanavalin A 자극으로 강한 증식유도능 및 interleukin-2 생산능을 나타내었고, 그 효과는 균사체 추출물에서 자실체 보다 더욱 높았다. 또 각 시료는 골수세포에 대해서도 약간의 증식효과를 보였으며, 복강세포의 탐식능을 나타내었다.

  • Background: Ginsenosides of Korean Red Ginseng extracts (RGE) and its saponin components suppress secretion of inflammasome-mediating cytokines, whereas the nonsaponin fraction (NS) of RGE oppositely stimulates cytokine secretion. Although direct exposure of NS to macrophages in mice induces cytokine production, oral administration of NS has not been studied in inflammasome-related disease in animal models. Methods: Mice were fed RGE or NS for 7 days and then developed peritonitis. Peritoneal cytokines were measured, and peritoneal exudate cells (PECs) were collected to assay expression levels of a set of toll-like receptors (TLRs) and cytokines in response to NS ingestion. In addition, the role of intestinal bacteria in NS-fed mice was assessed. The effect of preexposure to NS in bone marrow-derived macrophages (BMDMs) on cytokine production was further confirmed. Results: NS ingestion attenuated secretion of peritoneal cytokines resulting from peritonitis. In addition, the isolated PECs from NS-fed mice presented lower TLR transcription levels than PECs from control diet-fed mice. BMDMs treated with NS showed downregulation of TLR4 mRNA and protein expression, which was mediated by the $TLR4-MyD88-NF{\kappa}B$ signal pathway. BMDMs pretreated with NS produced less cytokines in response to TLR4 ligands. Conclusion: NS administration directly inhibits TLR4 expression in inflammatory cells such as macrophages, thereby reducing secretion of cytokines during peritonitis.

  • This report describes a case of postpartum uterine rupture associated with retained placenta and sequential acute metritis, not dystocia. A 14-month-old Bichon Frise bitch presented with continuous vaginal bleeding. She delivered five puppies 3 days ago and expelled four placentas on the next day. After then, anorexia, acute depression with continuous vaginal haemorrhage developed. Plain radiography showed decreased serosal detail, and ultrasonography showed irregularly thickened uterine wall and ascites. Blood-tinged peritoneal fluid was an exudate with bacteria. Ovariohysterectomy was curative for the patient, and four full-thickness perforated holes were identified on both sides of the uterine horns.

  • The thymus weight of the mouse was 54.1% in protein malnutritive diet group and 39.2% in group treated with saponin fraction of Panax ginseng in comparison to normal diet group. This decreasing effects of protein malnutritive diet and saponin fraction on the thymus weight practically disappeared after four weeks. The saponin fraction showed no effect on the spleen weight of the mouse. The supplement of the saponin fraction enhanced total peritoneal exudate cells, content of total serum protein and albumin content of the mouse, each 45, 8 and 10% respectively in comparision to that of normal diet group. And these values in protein malnutritive diet group were 61.2, 83.6 and 87.0% respectively in comparision to that of normal diet group, and recovered to the level of normal diet group by the supplement of the saponin fraction. The electrophoregram of the serum protein of the mouse fed with protein malnutritive diet was different from that of the mouse fed with normal diet, but this difference practically disappeared by the supplement of the saponin fraction.

  • The anititumor and immunologic activities of the glycoproteins extracted from sea cucumber (Stichopus japonicus) on mice bearing sarcoma 180 cells were investigated . Maximum tumor suppression (64%) occurred at the dose of 100mg glycoprotein/kg. The highest prolongation ratio was achieved at the level of 100mg/kg an dincreased by 395 more than that of control. Glycoproteins from sea cucumber exhibited direct cytotoxic effect on the tumor cells. Dose dependent increase of leucocyte, peritoneal exudate cell and weights of immunoorgans revealed the improvement of immunity. When the glycoportein-administered group was compared with the control, a significant difference was not noted in the clinico-chemical values such as S-GOT, S-GPT , alkaline phoshatse activity, total protein, cholesterol, triglyceride, urea nitrogen and glucose levels in blood. These results suggests that the antitumor activity of sea cucumber glycoprotein is associated with activation of cells in the immune system.

  • Polysaccharide fractions were prepared from Forsythia Corea by several different extraction schedules. The fractions obtained were designated as ForCo A, ForCo B and ForCo C respectively. ForCo C was further purified through Sephadex G 200 column chromatography and obtianed two subfractions (Coreana A, Coreana B). ForCo showed marked antitumor activity against sarooma 180 and its activity was dose-dependent. Coreana A, purified from ForCo C, showed somewhat higher antitumor activity. ForCo C increased the number of circulating leucocytes and peritoneal exudate cells, but didn't show any significant effects on the phagocytic activity and total serum protein level. Chemical analysis showed that ForCo C was composed of glucose, galactose, xylose and arabinose. A close relationship between antitumor activities and polysaccharide contents waw observed. These results indicate strongly that antitumor active principle of Forsythia Corea is polysaccharide.
