This study was attempted to investigate the effects of "Angelicae gigantis Radix extract" (AG.EX.) on the activities of GOT and GPT, the contents of total lipid, triglyceride, total cholesterol, phospholipid and ${\beta}-lipoprotein$ in serum, and the weight change ratio of body, liver and spleen in the experimentally induced hyperlipemic rats by administering the extract of 300 and 500 mg/kg p.o.. Significant test was performed by comparision with the biochemical values between control group and experimentally hyperlipemic rats. In the activities of s-GOT and s-GPT inhibition effects were significantly appeared in all dose of AG.EX. (especially more excellent in ethanol extract) and Angelicae acutilobae Radix extract (AA.EX.) as compared with the control group. The content of total lipid was remarkably decreased in all sample group when compared with the control group, and AA.EX. showed more excellent decreasing effect than AG.EX. The contents of triglyceride and total cholesterol were significantly lowered in all sample group, and more significantly decreased in water extract of AG.EX. and ethanol extract of AA.EX. The content of phospholipid was significantly decreased in all sample group and AG.EX. was more significantly decreased than AA.EX. The increasing rate of body weight in all sample groups except AA.EX. 500 mg/kg was increased more than control group and more significantly remarkable in dose of 300 mg/kg than 500 mg/kg. The increasing rate of liver weight in all sample groups was increased more than control group, and AG.EX. was more increased than AA.EX.

배경: 폐암은 근치적 절제술이 가장 좋은 치료법이나 수술 후에 재발한 경우나 수술 시기가 지난 경우에는 항암 화학요법의 중요성이 강조된다. 항암 치료 전에 감수성 있는 항암 화학 치료제가 선별되어진다면 치료 효과를 극대화할 수 있다. 신피막하 분석법은 흉, 복부 종양의 생체 내 검사법으로 중요성이 인정되고 있고 항암 감수성 검사로서도 짧은 기간 내에 판별이 가능한 이점이 있다. 신장은 각종 암세포의 이식 장소로 잘 알려져 있으나 비장이나 간에서의 이식 성적을 비교한 연구는 없는 실정이다. 인체 암세포 이식의 실험방법 중에 비장과 간장에 암 세포주를 이식하였을 경우와 신장에 시행되는 신피막하 분석법에 의한 성장의 차이점 유무를 평가하였다. 대상 및 방법: 인체 폐암 세포주(SW-900 G IV)를 RPMI 1640 (Leibovitz L-15 medium)배지에서 배양하여 fibrin clot으로 만들어 $10^{8}$ 개의 암세포가 포함되도록 한 후 3${\times}$${\times}$3mm의 크기로 Spague Dawely (S.D.) 암컷 쥐의 신, 비장 및 간 피막하에 이식하였다. 이식 후 1일부터 6일간 면역억제를 위하여 cyclosporin-A (80 mg/kg)를 피하투여하였다. 이식 전후 실험동물의 체중 변화, 종양의 성장 여부 및 종양의 크기를 계측하고 병리 조직 검사와 혈청 내 암 표지자 검사를 실시하여 비교하였다. 걸과: 실험 5.D. 쥐의 체중 변화는 대조군이나 실험 군 모두에서 체중 증가가 있었다. 혈청 내 암 표지자의 정량 검사 결과 Cyfra 21-1은 검출되지 않았고, CEA및 NSE는 의미 있는 변화가 없었으며, SCC-Ag이 실험 군에서 유의한 증가가 있었다. 비장에 이식한 폐암 세포주의 성장이 신장 및 간장에 비해 더 증가된 결과를 보였다. 표면적, 두께와 용적 모두가 비장에서 유의한 증가를 나타내었다. 이식 성공률은 신장이 80%, 비장이 76.7%, 간장이 43.3%이었다. 병리학적 검사 결과 신장에는 비교적 둥글게 성장하며 크기는 제일 작았으며 성장 방향이 일정한 모양을 보이는 특징이 있으며 비장은 성장이 잘되어 제일 큰 종양을 형성하나 불규칙한 성장과 위성 종양(satellite tumor)이 빈번히 발견되었으며 현미경적으로는 혈관 신생과 함께 종양 혈전이 발견되었다. 간장은 간 내부로 침투 성장하여 이식 성공률이 가장 저조하며 현미경적 소견은 응고성 괴사와 점액양 섬유성 병변을 가지는 특징을 보였다. 걸론: 이식 성공률은 신장과 비장이 높으나, 성장이 일정하고 계측이 용이한 것은 신장이었다. 혈청 암 표지자는 SCC-Ag이 가장 조기에 반응하였으며, Cyfra 21-1은 조기에 검출되지 않았다. 이상에서 감수성 검사를 위한 종양이식 실험에 이용하기에 가장 적합한 장기는 신장을 이용한 신피막하 이식법으로 생각되며, 조기에 유용한 암표지자 검사는 SCC-Ag 정량법이라고 판단된다.

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.

The effects of oligosaccharide supplementation on the growth performance, flock uniformity and GIT development of broiler chickens were investigated. Four diets, one negative control, one positive control supplemented with zinc-bacitracin, and two test diets supplemented with mannoligosaccharide (MOS) and fructooligosaccharide (FOS), were used for the experiment. Birds given MOS or FOS had improved body weight (BW) and feed efficiency (FCR), compared to those fed the negative control diet during the 35-d trial period. The effect on FCR became less apparent when the birds got older. FOS and MOS supplementation reduced the pancreas weight as a percentage of BW, with an effect similar to that of the antibiotic, at 35 d of age. Birds given MOS tended to have a heavier bursa (p = 0.164) and lower spleen/bursa weight ratio (p = 0.102) at 35 d of age. MOS and Zn-bacitracin showed a clear improvement on flock uniformity, compared to FOS. The mortality rate was not affected by FOS or MOS.

DA-125, a new anthracycline antitumor antibiotic, was administered to Sprague-Dawley rats intravenously for 4 weeks to investigate the repeated dose toxicity Focal alopecia was noted in three female rats receiving 1.0mg/kg/day. In rats receiving 1.0 mg/kg/day, weight gain decreased in both sexes after first or second week. Hematological examination revealed lower counts of total leukocyte and increased numbers of platelet after second week. At terminal necropsy, atrophy of thymus and spleen was observed. Lymphocytic depletion of thymus and atrophy of white pulp in spleen were observed microscopically. A decrease in the number of hematopoietic cells in the bone marrow and degeneration of germinal epithelia in testes were also observed. These treatment-related effects were mainly confined to rats receiving 1.0 mg/kg/day. And toxic effects with microscopic changes were not observed in rats receiving 0.2 mg/kg/day or 0.04 mg/kg/day.
