돼지 난포의 폐쇄기 작을 규명하고 폐쇄난포의 판정기준을 보완, 확립하기 위하여 난포의 크기 및 상태 그리고 난소주기에 따라 Acid phosphatase(Acpase)의 활성부위와 활성도를 조사하였다. Acpase의 활성부위는 과립세포와 난포막내층이었고, 반응정도는 난포 :극 대난포와 중난포의 경우 정상군에 비해 폐쇄군에서 강한 반응을 보였다. 황체기난포의 과립세포에서는 중난포와 소난포 모두 반응이 미약하였고, 난포막층에서는 정상군과 폐쇄군 모두 강하게 나타났다. Acpase의 활성도는 난포기 난포의 과립세포에서 난포가 커짐에 따라 증가하였는데 난포막층의 활성도는 감소하였으며 , 폐쇄군이 높은 활성도를 보f:다. 황체기의 경우 반포기와는 달리 과립세포와 난포막층에서 난포가 커짐에 따라 활성도는 감소하였으나 폐쇄군은 역시 높았다. 이상의 결과에서 폐쇄난포의 Acpase의 활성부위와 활성도는 정상난포에 비하여 뚜렷하고 강하여서 이 방법은 폐쇄의 판정기준으로 이용 가능한 것으로 사료된다. 또한 난소주기에 따라 상이한 결과를 나타낸 것은 폐쇄기 작이 서로 다름을 시사하였다.

This study was performed to investigate the influcence of mugwort on the duodenal ulcer induced by cysteamine administration in rats. Five groups of rats were fed each experimental diet containing 0%, 5%, 15%, 30% of mugwork powder for 10 weeks. Duodenal ulcer was induced by cysteamine injection (400mg/100g body weight) after 10 weeks of feeding experimental diets (C-0, C-5, C-15, C-30). Control animal that fed 0% mugwork powder added diet were injected saline (S-0) to compare with cysteamine injected groups. When the duodenal ulcer induced by cysteamine-HCI administration, all animals in the C-0 group formed erosion and perforating ulcer was found in 44% of animals. Higher the added mugwork ratio, more inhibited of the duodenal ulcer induced by cysteamine administration (C-5, C-15). But when the ratio of added mugwort is 30%, the inhibition effect disappeared (C-30). The alkaline phospatase activities were lower at the duodenal mucosa and small intestinal mucosa in the cysteamine treated groups(p<0.05). The acid phophatase activities were higher at the stomach, small intestine and large intestine of the cysteamine treated groups. But in mugwort added diet group, the changes of enzyme activites were lessended. The maltast activities were lower at the duodental mucosa and small intestinal mucosa of cysteamine treated groups. But in mugwort added diet group, maltase activites were recovered.

This study compared the characteristics of five Bacillus strains capable of aerobic and anaerobic growth, CBW3, CBW4, CBW9, CBW14 and EBW10. They were isolated and selected from a polychaete, Perinereis aibuhitensis, which is known as a good degrader of organic compounds in marine wetland. Based on a 16S rRNA sequence, CBW3 and CBW14 were found to share more than 99.8% similarity with B. nanhaiensis, B. arsenicus and B. barbaricus. CBW4, CBW9 and EBW10 shared 92.7%, 99.8%, and 99.8% similarity with B. anthracis, B. algicoa and B. thuringiensis, respectively. The temperature, salinity, and pH ranges of the cell growth of the Bacillus strains were $4-45^{\circ}C$, 0-17%, and pH 5-pH 9, respectively. All Bacillus strains were found to exhibit enzyme activities for the degradation of casein and starch. Notably, strain EBW10 exhibited the enzyme activities for all the tested macromolecules, DNA, casein, starch, cellulose, and four kinds of Tweens, which suggests the possibility that it had protease, amylase, cellulose, and lipase. All five Bacillus strains had alkaline phosphatase activities, and the strains CBW3, CBW4, and EBW10 also had acid phospatase. Strains CBW3 and EBW10 exhibited the enzyme activities both for esterase (C4) and esterase lipase (C8). The analysis of fatty acids revealed that in all strains, major fatty acids were anteiso $C_{15:0}$ and iso $C_{15:0}$.

It is reported that Pueraria Radix contains phtoestrogens whereas flower, and bud of Pueraria lobata Ohwi were not known. In the present study, we determined the amount of phytoestrogen in each portion of P. lobata Ohwi and carried out therapeutic effects of osteoporosis. The amounts of genistein, daidzein, and formononetin in Pueraria Radix (PR), Pueraria Flos (PF), and young Pueratia Folium (PL) were quantitated using a HPLC system. Proliferation of osteoblast and growth inhibitory effect on osteoclast were measured in order to screen their effects on osteoporosis. Proliferation of osteoblast-like cells (Saos-2) was analyzed by both MTT methods and alkaline phosphatase (ALP) assays. Growth inhibitory effect on osteoclast was also detected as Tartrate resistant acid phosphatase (TRAP) assay. Ovariectomized rat as an in vivo animal model was selected and administrations of PR were 1 g/kg/day (PR-1) and 5 g/kg/day (PR-5) for 9 weeks, respectively. Trabecular bone areas (TBAs) of tibia and lumbar were analyzed usibg histomorphological methods. Results show that PR contains the highest level of daidzein ($10435{\pm}2143\;mg/kg$ of dried herb) and stimulated ALP activity, approximately 160% of the control. Growth inhibitory effect on osteoclast by both PR and daidzein were almost identical with control although $IC_{50}$ of genistein was $5.81{\times}10^{-7}$ M. Increases in body weight of OVX rats were suppressed by administration of PR but wet weights of uterus in PR-5 group were increased (p<0.05). Plasma ALP and HDL-cholesterol levels were decreased following ages (p<0.01), and LDL-cholesterol level was also decreased in PR-5 group at 20 week of age (p<0.01). TBAs of tibia and lumbar in PR-1 and PR-5 groups were higher than those of the control although the values were less than those of the sham group (each p<0.01) In conclusion, administrations of PR prevented loss of TBAs of tibia and lumber in OVX rats, while PL and PF did not (p<0.01).
