We, investigators made a survey on the species, regional distribution and toxic chemical components of the poisonous plants in Cheju island from March to Nov. 1974. The results obtained were as follows : 1. If not all, 86 species(65 spp. of herbs(inbolvlng ergot), 21 spp. of shrubs) within 42 families of the poisonous plants distributed in this Cheju area were classified. 2. According to their regional distribution, 36 spp, were in wild, field, 34 spp. in jungle area, 21 spp. in inhabited region, 15 spp. in a region of seashore, 5 spp. in a mountainous area. 3. And according to their toxic chemical components or poisoning types, they were classified as 7 spp. of cyanogenetic plants, 8 spp. of photosensitization, 6 spp. of oxalate-producing plants, 3 spp. of producing a thiamine deficiency, 2 spp. of teratogenetic effect, 1 sp (ergot) of gangrene production and 59 spp. of the other activities. 4. Actually, the bracken fern(Pteridium nquilinum) is a most problematic poisonous plant in livestock, because it is so high in frequecy or in this Cheju island. But, of course, it will be a nonsense to despise lots of the other poisonous plants.

Because c very little information available regarding the poisonous plants distributed in Cheju-lsland, the author made a survey of such plants from March. 1974 to Dec., 1977. The results obtained were as follows: 1. If not all, 68 families, 137 genera and 190 species of poisonous plants distributed in Cheju-island were classified. And 190 species were divided into 137 spp. of herbs, 45 spp. of shrubs, 3 spp. of molds and 5 spp. of toadstools. 2. Relatively, a large number of poisonous plants were distributed in wild field. Jungle area, inhabited region, seashore and high mountainous area took next place gradually by the number of plants. 3. And according to their toxic chemical components or poisoning types, they were clas-sified as 16 spp. of cyanogenetic plants, 14 spp. of oxalate-producing plants, 14 spp. of nitrate-producing plants, 10 spp. of photosensitization and 136 spp. of the other activities.

Equine bones including one phalanx 3 and three teeth excavated from Kwakji archaeological site, were morphologically examined, Compared with the Cheju pony and the Thoroughbred horse, the significance of the observations were tentatively evaluated. It was suggestied that the larger-limbed horses than the present Cheju pony inhabited in ancient Cheju island.

Holstein 송아지에 있어서 中等度의 倂發性 鼓脹症으로 인한 斃死例

梁奇千 제주대학교 1978 논문집 Vol.10 No.-

Two Holstein calves were come to sudden deaths resulted from a moderate intercurrent acute bloat without earlier symptoms on Oct. 7 and Oct. 31, 1978. These two calves showed the results summarized as follows through a routine postmortem examination and blood smear. Case 1: This female calf, 14 months old, was in progress with moderate bracken poisoning. In addition, the intercurrent ruminal bloat outbreak was fatal dicisively with a potentiate general anoxia through difficulty in general circulation and dyspnea. Case 2: This male calf, 3 months old, had been suffered from superinfections of chronic bronchopneumonia, calculus within ureter and anemia. As a result of these ab normalities, this calf was in a state of cachexia and loss of enteric peristaltic movement with resulted from chronic peritonitis was observed. Moreover, the intercurent acute ruminal bloat followed from overloading feed with combined fodder was fatal definitively. The above mentioned two cases of sudden deaths suggested that an intercurrent bloat, even if it's not a severe case, might be fatal in a state of erythropenic anemia which resulted from braken poisoning and other causes. Also, in general cachexia and declines of enteric peristalsis, the fatal secondary bloat might be developed easily by overloading feed.

The authors obtained the following results from the research project they completed in the laboratory, the experimental animal stalls of Cheju college and the south area of Cheju-do. The strains of ticks used in the research were Boophilus microplus and Haemaphysalis bispinosa. The ticks which were present in the south area of Cheju-do seemed to have a resistance to the chlorinated hydrocarbons. The effects of each ixodicide were as folows: Organic phosphorous insecticides were most effective and Carbomates (especially Sevin(0.5%) were effective but not so good as the organic phosphatos. And the chlorinated hydrocarbons were poor in tickicidal. effect, but r-BHC (0.03%) and Dieldrin(0.1%)were better than the other Chlorinated hydrocarbons. Among the Organic phosphates, Dursban (0.03%) and Dipterex(0.1%) were most effective and Asuntol(0.05%) was also effective. In various compounds, MBD(0.1%) (Compound of malathion, r-BHC and DDT), DA(0.1%) (Compoud of Dipterex and Aldrin) and MA(0.1%) (Compoud of Malathion and Aldrin) were most effective. These compounds were much better in tickicidal effect and toxicity than the Organic phosphates and Chlorinated hydrocarbons alone. As a result, the authors now recommend MBD, DA, MA and Dipterex as the most practical ixodicides in this year for Cheju area by reason of their effectiveness, lower cost and low toxicity.

Carbon Tetrachloride의 독성에 미치는 Chlorpromazine의 영향

양기천 제주대학교 1969 논문집 Vol.1 No.-

The author investigated the influences of Chlorpromazine(CPZ) on the acute CCl₄ toxicity by measurement of S-GOT, S-GPT activities and LD??. Animals used were healthy mice weighing 20-30g and healthy albino rabbits weighing 1.7-2.2kg. The LD?? was estimated by Behrens- Kaerher method and S-GOT and S-GPT activities by Reitman-Frankel method. The results obtained were summarized as follows. 1. The LD?? of CCl₄in control was 10.7ml/kg b. w. for grouped mice. When, however the grouped mice was pretreated with CPZ (5mg/kg.), it raised the LD?? of CCl₄as 14.0 ml/kg. (Table 1) 2. The activities of GOT, GPT in the rabbit blood serum pretreated with CPZ seemed to be increased slightly in comparison with them of CCl₄alone, but it was not significant. (Table 2,3, Fig. 1,2)

Organic nitrogen and mineral contents in so, forages and blood serum of beef cattle sampled in June-July and September-October in 1987 from 12 different pasture areas of Cheju island were determined and the results are summarized as follows: 1. The contents of all mineral studied were significantly different (p<0.01) between soils of different pastures sampled in June-July. and the contents of P, Mg, Fe, Na. Ca and Zn were significantly different (P<0.01) between soils of different pastures sampled in September-October. The contents of P and Ca were much higher in soils sampled in June-July than in soils sampled in September-October. but the contents of K and Mg were opposite to those of P and Ca. 2. N, P, Mg. Cu and Co contents of orchard grass sampled in June-July were significantly different (P<0.01 ) between the pastures, and K, Ca, Mg, Na and Co contents of orchard grass sampled in September-October were significantly different (P<0.01) between the pastures. Cu, Fe, Na, Cu and Zn contents were higher in orchard grass sampled in September-October than in that sampled in June- July. 3. Except for Mg, mineral contents of ladino clover sampled in June-July were different between the pastures, and N, Ca, Mg, Fe, Na and Zn contents were significantly higher in ladino clover than in orchard grass. 4. The contens of Zn and Fe in blood serum of beef cattle sampled in June-July were significantly different (P<0.01) between the pastures and the contents of K, Ca, Mg, Na and Co in that sampled in September-October were different between the pastures. No difference was found in serum mineral contents between beef cattle from different pastures. 5. Serum Co content (0.07ppm) in the cattle raised in lsidore was below the normal, Co deficiency being suspected. Serum contents of the other minerals were found to be normal in the cattle of all pastures. 6. Only Fe content was significantly (p<0.05) correlated between the content of forages and the blood serum(R=0.84).
