Paenibacillus larvae는 Gram양성의 내생포자 형성 세균으로, 꿀벌의 질병 중 가장 심각한 피해를 입히는 미국부저병(AFB)의 원인균이다. 이 P. larvae를 발병전인 봉군 또는 애벌레에서 보다 빠르게 검출하기 위하여 기니아피그를 이용하여 이 병원균에 대한 다클론 항체를 제작하였고 또한 그 항체의 성능을 평가하였다 제작된 항체를 이용한 ELISA검색법을 개발한 후, 다수의 P. larvae균주를 검사하였다. 그 결과 P. larvae ATCC 25748의 균체를 사용하여 제작된 항체는 ATCC 9545 (대표균주), ATCC 25747, 국내 분리 균주인 SJl5등과 높은 항체 친화성을 나타내었으며. 다른 세균 종들과는 반응하지 아니하였다. 또한 이 ELISA검색법은 미국 부저병의 현장검사에 적용하기 위하여 사용되었으며, 그 결과로 본 연구에서 제시하는 항체는 벌집 내 또는 애벌레 내에 존재하는 P. larvae의 빠른 동정과 모니터 링에 매우 유용함을 보여주었다.

Counts of RBC and proportion of packed cell volume(PCV) showdc no difference among treatment groups. the values of hemoglobin in rat showed a tendeuy to increase in herbal-acupuncture group, however the values of hemoglobin in guineapig and rabbit showed no significant difference in the treatnent groups. the count of WBC showed high in the chishiI(BL52) herbal-acupuncture group. The proprtion of neutrophils showed no significant difference in rabbit, however the values in guinea-pig and rat showed a tendency to increased in herbal-acupuncture groups. The proportion of lymphocytes in rabbit and guinea-pig showed a tendency to decreast in herbal-acupuncture groups, however the values in rat showed no significant difference. The proportion of Eosinophils and monocytes showed no significant difference in all the treated groups. Results from this study indicated that shinsu(BL23) and chishil(BL52) herbal-acupuncture with palmijihwangtang elivate the biglogical function in Rabbit Guinea-pig and Rat.

This study was carried out to investigate the effect of Yeemosan extract on the contractile force of the isolated guinea pig trachea smooth muscle and elucidate its mechanism. The results were obtained as follows: 1. The contractile response of the trachea smooth muscle of isolated guinea pig to acetylcholine was significantly inhibited by Yeemosan. 2. The contractile response of the trachea smooth muscle of isolated guinea pig pretreated propranolol was significantly inhibited by Yeemosan. 3. Effects of Yeemosan extract on the contractile response of the isolated guineapig trachea smooth muscle pretreated methylene blue was not significant. 4. The contractile response of the trachea smooth muscle of isolated guinea pig to prostaglandin $F2{\alpha)$ was significantly inhibited by Yeemosan. 5. Effects of prostaglandin $F2{\alpha)$ on the contractile response of the isolated guinea pig trachea smooth muscle pretreated Yeemosan was not significant. According to the above results. it was suggested that the contractile response mechanism of the guinea pig trachea smooth muscle to Yeemosan was related to sympathetic nervous system receptor and other mechanism should have further study.

The survey was conducted on the actual conditions of species, the facilities, a establishment of regulation concerning laboratory animals and the related problems on users and suppliers of laboratory animals in Korea. The questionnaires were sent to 430 and received from 107$(24.9\%)$ places. The results obtained were as follows : 1. Experimental animals used at the 107 places were 21 species: mouse(90\;places,\;84.1\%)$, rat $(61,\;57.0\%)$, rabbit$(76,\;71.0\%)$, guineapig$(42,\; 39.3\%)$ etc. 2. The main organizations using laboratory animals were university $46(43.0\%)$, institute $32(29.9\%)$ and pharmaceutical company $27(25.2\%)$ etc. 3. Most the laboratory animal facilities in Korea have been conventional system without environmental controls, but a few places have been recently established barrier system. 4. To get a good experimental result, a regular genetic and microbiological monitoring of laboratory animals should be done. 5. It was required that a educational facilities and a quality test agency for laboratory animals should be established. 6. It was also required that a regulation for breeding and using of laboratory animals should 'be enacted.

The hyalinized zone in compressed periodontal ligament seems to be an unavoidable aspect during certain phases of orthodontically produced tooth movement. And these hyalinized zones leads to a standstill of tooth movement. But when hyalinized zones disappears after a certain period of time and tooth movement is established. In the basic aspect of clinical science of orthodontics, it is very important, to study about the process involved and to establish whether a difference of periodontal response by the amount of the applied experimental force exists. The 35 Guineapigs were divided into the control group (5 animals) and the experimental group (Group I-Group VI 30 animals). The experimental tooth movement of Guineapig's maxillary incisors were carried out by rendering continuous force, 5g (Group I, Group II) 35g (Group III, Group IV), 100g (Group V, Group VI) respectively. 15 animals (Group I, Group III, Group V) were sacrificed one week after this experiment. Another 15 animals (Group II, Group IV, Group VI) were sacrificed one week after the removal of active appliences. At the end of the experimental periods, specimens containing tooth and adjacent periodontal structure were obtained and processed for light and electron microscopy. The results were as follows: 1. In Group I, cellular changes of pressured zones showed swollen mitochondria, dilation of rough surfaced endoplasmic reticulum (RER), vesicles and pyknosis of nucleus. 2. In Group III and Group V, the hyalinized tissues showed cell necrosis accompaning ruptures of cytoplasmic membrane and perinuclear envelope, large cytoplasmic vacuoles and many necrotic cell debris. 3. In Group IV and Group VI, hyalinized tissue were eliminated and the primitive mesenchymal cells and blood capillaries were proliferated. 4. In group V, the destruction of the collagenous fibers were observed, while in group I and group III were not observed. 5. In Croup IV and Group VI, the hyalinized zones were still remained partly.

A polysaccharide, G009, isolated from Ganoderma lucidum IY 009, was subjected to investigating on general pharmacology. This material at the large oral doses of 1000 and 2000 mg/kg in mice did not exhibit any abnormal behaviors and another effects on central nervous system. It also had no influences on hexobarbital-induced sleeping time, rotarod test and spontaneous activity test at each oral dose of 1000 mg/kg in mice. No effects on the body temperature and on acetic acid induced writhing syndrome in mice were observed with its oral administration at 1000 mg/kg, and the convulsions induced by strychnine and pentetrazole were not inhibited at its oral doses of 1000 mg/kg in mice. The solution of G009 as given intravenously at the doses of 30 and 60 mg/kg in rabbit had no influences on blood pressure and respiration rates and depth. In isolated organs of rat uterus and fundus muscles and guineapig ileum and trachea, it did not show any contraction or relaxation at the concentrations of 2$\times$10$^{-3}$ g/ml, and the contractive actions produced by oxytocin, acetylcholine, serotonin and histamine were not inhibited at the same doses. This material showed no effect on intestinal propulsion test in mice and gastric secretion in rats at the oral doses of 1000 mg/kg. However, it is interesting that the material exhibited potent inhibition of acidified aspirin induced gastric damage at the doses of 500 and 1000 mg/kg in rats.
