연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Chines herbs nephropathy (CHN) has been described in young women who had taken a slimming pills containing some chines herbs. Aristolochic acid (AA), suspected substance as the causal factor of CHN, is known a carcinogen. The Aristolochiae fructus (fruit of Aristolochia contorta) was used in Korean Traditional Medicine consists of appropriate amounts of mixed natural products. Subchronic toxicity of A. furctus containing aristolochic acid was investigated in SD rats. The body weight and clinical signs were observed after orally administration of A. futctus at doses of 21.2, 213, and 2130 mg/kg/day; mixture (including 9 other herbs) at dose of 427 mg/kg/day; aristolochic aicd (Ⅰ+Ⅱ) at doses of 0.05, 0.5, and 5 mg/kg/day for 3 months. At the end of the treatment, high dose treated animals revealed a deficit in final body weight about 25% compared with that of control. Organ weights of kidney, liver, testis, or ovary were increased with dose dependent manner. No changes considered to be due to the administration of A. furctus, mixture or aristolochic acid were in hematological and clinical study. However, significant changes at histopathological study of kidney and stomach were boserved in high-dose treated groups. In conclusion, for human health safety it needs appropriate regulatory actions regarding the use of natural herbal medicines known or suspected of containing aristolochic acid.

The concept of PCA(Patient Controlled Analgesia) was first described in 1968, by Sechzer. The earliest descriptions of actual self-administered PCA machines were by Forrest et al. In gastric bypass surgery, cesarian section, orthopedic surgery etc, PCA is widely used in the control of postoperative pain. Previous Studies have shown that PCA provides effective pain-control for the postoperative patient. The postoperative pain-control is a problem that should be solved in surgery. Especially in orthognathic surgery, it is not same as in the case of maxillofacial trauma surgery or of tumor surgery : most orthognathic surgery patients are under operation not accustomed to pains, and difficulties in pain-complaint due to IMF(Intermaxillary fixation), postoperative nausea, and vomiting are additional problem. In this study, we have compared PCA and IM analgesics with respect not only to time request but also to the quality of postoperative pain control.

Control of blood pressure is affected by regulation of intrarenal blood flow. Renal sympathetic nerve simulation inhibits pressure-depressor mechanism of kidney. This antidepressor mechanism was known as happening to due to a decrease the blood supply of renal medulla. It is not known whether renal sympathetic nerve innervation of renal medulla is and it affects regulation of medullary blood flow. We tried to measure total renal blood flow(TRBF), cortical blood flow(CBF), papillary blood flow(PBF) by ultrasonic and laser Doppler techniques in Wistar rats during 3 kinds of renal sympathetic nerves stimulation. The simulation orders are tried randomly and each stimulation period is 15 minute. TRBF and CBF decreased at 1 Hz by 2 and 2%, 3Hz by 18 and 15%, 5Hz by 49 and 44%, respectively as similar to each other. But PBF increased by 1% at 1 Hz and 4% at 3 Hz, while it decreased by 4% at 5 Hz. Therefore, it seems superficial renocortical and total renal blood flows are closely regulated by renal sympathetic nerves with increasing vasoconstriction at 5 Hz, onthe other hand while medullary blood flow seems to be under strong local control, tending to offset neurogenic flows restrictions.

This study was planned to analyze amino acids in the septal nucleus of dorsal and ventral hippocampectomized rats by high performance liquid chromatography (HPLC). Male albino rats were used. Under chloral hydrate anesthesia (20%, 2 ml/kg body weight), a hole was made in each parietal bone about 4 mm lateral to the sagittal suture, and 4 mm rostral to the lambda suture. The cortical tissue on each side was removed and, through this opening, the hippocampal tissue anterodorsal and posteroventral to the hippocampal flexures on both sides was removed by aspiration. This preparation served as the dorsal and the ventral hippocampal animals, respectively. The cortical control animal received the same surgery short of hippocampectomy. The normal rats served as normal control animal. One day later, the animals were sacrificed by decapitation in the cold room. Two to three milligrams of tissue was obtained form the septal nucleus in one side of the brain. The tissue samples were homogenized and centrifuged. Then content of each amino acid was measured by HPLC form the brain tissue. The contents of aspartate and glutamate were decreased significantly more in the dorsal and ventral hippocampal groups than in the normal and the cortical control groups. The contents of glutamate were decreased significantly more in the ventral hippocampal group than in the dorsal hippocampal, while there were no significant differences between the two control groups. It is inferred form the above mentioned results that glutamate and aspartate may be used as excitatory transmitters in septal nucleus, and that the dorsal hippocampus may be facilitatory to the septal nucleus, but the ventral hippocampus would be inhibitory/facilitatory to the cortex.
