N/A Clinical observations were made on 24 cases of acute drug itoxication who were admitted to the Department of Internal Medicine, Pusan Adventist Hospital from January 1984 to December 1987 and the following results were obtained. 1) The total number of cases of acute drug intoxication was 274 which was 0.94% of the total patients of the emergency room. 2) The ratio of male to female was 1:1.8 The age incidence was highest in the 3rd decade age group (38.7%). 3) The incidence was highest in May and during the spring season. 4) The motive for intoxication was suicidal attempt in 87.3% and accidental poisoning in 21.8% of cases. 5) The most common drug of intoxication was sedatives (26.6%) and the others were rodenticides, pesticides, and miscellaneous unknown drugs in order. 6) Most cases complained of impairment of conscious- ness. Vomiting, abdominal pain and convulsion were frequently observed. Physical examination revealed increased pules, increased blood pressure, sweating, increased bronchial secretion and miosis of the pupil, Such symptoms and physical signs were more prominent in pesticide intoxication. 7) Leukocytosis was common in pesticide intoxication (54.0%). 8) The overall mortality rate of total cases was 4.7% and the mortality rate was highest in pesticide intoxication.

웅성-마우스의 고환을 diethyl ether마취하에서 제거하고, 수종의 steroid 홀몬을 각각 매일 1회씩 4일간 피하주사한 다음 날의 오전 11-12 시에 뇌, 신장, 간장 및 소장의 polyamine을 검량하여 다음의 성적을 얻었다. 1. 고환절제-마우스(CM)에서, 소장 putrescine(PT)는 비고환절제-마우스(UCM)에 비하여 유의한 저하를 보였으나, 간 및 소장의 spermine(SM)은 오히려 유의하게 증가되었다. 2. Hydrocortisone 50 mg/kg는 UCM의 소장 PT는 현저히 증가시켰으나, CM의 뇌 PT 함량은 오히려 감소시켰다. 3. Estradiol 5 mg/kg는 UCM의 간 PT 함량을 현저히 증가시켰으며, CM에서는 간 PT 뿐만 아니라 신장의 전 polyamin 함량-증가와 아울러, 다소의 뇌 및 소장 PT-증가를 유도하였다. 4. Dehydroepiandrosterone 250 mg/kg(DHEA)와 testosterone 5 mg/kg(TS)는 UCM의 경우 신장 PT 함량만 유의하게 증가시켰으나, CM에서는 신장의 PT, spermidine(SD), 및 SM 모두를 더욱 현저히 증가시켰고, 아울러 DHEA는 간 SM의 감소를, TS는 뇌 SM의 유의한 증가를 유도하였다. 이상의 결과로 미루어 볼때, 간 및 소장의 polyamine대사-특히 PT함량의 변동은 각각 E2 및 HC에 의하여 보다 특이적으로 조절되고, 신장의 polyamine 대사는 성steroid들에 의하여 다소 비특이적인 조절을 받는 것으로 생각되며, 고환절제-마우스에서 나타나는 HC에 의한 뇌의 전potyamine감소 및 성steroid들에 의한 신장의 전polyamine증가의 발현기전에 대한 연구가 있어야 할 것으로 사료된다. The bilateral castration of male mice was operated under light ether anesthesia, and the sham operated mice were considered as the uncastrated. The treatments of mice with the following steroids were started one hour after operation. Hydrocortisone 50 mg/kg (HC), dehydroepiandrosterone 250 mg/kg (DHEA), ${\beta}-estradiol$ 5 mg/kg (E2), and testosterone 20mg/kg (TS) were subcutaneously injected into male ICR mice at noon for four days. Animals were sacrificed in the next-morning (at 10-12 A.M.) after the last injection. The intestinal putrescine(PT) content was lower and the liver and intestinal spermine(SM) contents were higher in castrated mice(CM), comparing with those of uncastrated mice (UCM). The intestinal PT content of UCM was markedly increased HC. But all brain polyamines of CM were significantly decreased by it. And HC also increased the spermidine(SD) content of kidney and liver and the intestinal PT content in CM. E2 induced the marked increase of liver PT content with the moderate increase of renal SD in UCM. And E2 significantly increased the brain and liver PT contents and the all renal polyamine contents in CM. Both of DHEA and TS induced the increase of renal PT content in UCM, and they also induced the marked increases of all renal polyamines of CM. In addition, TS increased the brain SM of CM. These results suggest that the steroidal regulation mechanism of brain, kidney, liver, and intestine seems to be different from one another, and the renal activity of polyamine synthesis can be markedly enhanced by sex steroids.
