BACKGROUND: Induction of anesthesia with propofol commonly associated with reduction in systemic arterial pressure, especially in elderly and high risk patients. This reduction is influenced by the dose and rate of propofol injection. The aim of this study was to examine the effect of different injection rate of propofol on vital signs, dose requirement and induction time during induction period. METHODS: Unpremedicated one hundred and twenty ASA physical status I and II patients aged 20~60 years scheduled for elective surgery were randomly allocated into one of four (150, 300, 600, 1200 ml/hr) groups according to speed of injection of propofol during induction period. Loss of verbal contact was taken as the end-point of induction. Vital signs, SpO2, dose requirement of propofol and induction time were checked. RESULTS: As the injection rate of propofol became slower, there were significant reduction in induction dose and increase in induction time (p<0.05). For example, induction dose and time were 1.82 mg/kg, 223 +/- 58 sec in 150 ml/hr group and 3.14 mg/kg, 50 +/- 11 sec in 1200 ml/hr group, respectively. Also, decrease in systolic and diastolic pressure were less marked at lower injection rates. CONCLUSIONS: Slower injection of propofol produces less vital sign changes and dose requirement for the induction of anesthesia.

Nausea and vomiting are common problems after strabismus surgery in pediatric patients. We compared the effects of droperidol and ephedrine with conventional regimen consisting of halothane-N2O to the effects of conventional regimen itself, 69 children. ASA physical status l, ages 1-12yrs, were studied. Each child was randomly assigned to receive droperidol 0.04mg/kg., ephedrine 0.5mg/kg or normal saline 2ml intramuscularly, 10 minutes before the end of surgery. The incidence of postanesthetic nausea and vomiting was 17% in the droperidol group(p<0.05)., 13% in the ephedrine group(p<0.05), which were significantly less than the control group(43%). But there was no significant difference between droperidol group and ephedrine group. We concluded that droperidol and ephedrine have significant postoperative antiemetic effect in patients undergoing strabismus surgery.

It is well known that hypertension is associated with left ventricular diastolic dysfunction which frequently precede systolic dysfunction. To determine whether nifedipine could improve left ventricular diastolic function in hypertensive patients, we studied 15 hypertensive patients and 15 normotensive subjects matched for sex, age with Doppler echocardiography. After oral administration of 10mg of nifedipine, there were no significant changes in Doppler-derived transmitral diastolic filling indexes of normotensive subjects. On the other hand, although peak flow velocity in atrial systole(PFVA), time velocity integral in atrial systole(TVIA) did not change significantly after nifedipine, nifedipine significantly increased peak flow velocity in early diastole(PFVE) from 40.2+/-6.4cm/sec to 46.5+/-10.9cm/sec(p<0.005), time velocity integral in early diastole(TVIE) from 5.24+/-1.2cm to 5.97+/-1.43cm(p<0.001), the ratio of PFVE/PFVA from 0.69+/-0.11 to 0.76+/-0.12(p<0.05), the ratio of TVIE/TVIA from 1.18+/-0.21 to 1.29+/-0.24(p<0.05), deceleration slope(DS) from 244.9+/-51.9cm/sec2 to 289.9+/-49.1cm/sec2 (p<0.001) and decreased isovolumic relaxation time(IVRT) from 132.3+/-10.3msec to 117.2+/-13.5msec(p<0.001), deceleration time(DT) from 168.8+/-30.3msec to 154.9+/-29.8msec(p<0.05) in hypertensive patients. These fimdings indicated that nifedipine improves Doppler-derived early diastolic filling indexes in hypertensive patients and may be related to improvement of active relaxation of left ventricle in early diastole.

[Objective] It makes a through study on the popularization and usefulness plan of Moxa Combustion, therefore popularizing practical use of that.
[Methods] It was based on the established treatises and books, in order to studying about the literature of Moxa Combustion.
[Results & Conclusions] It makes a through study on the whole of Moxa Combustion, the results as follows.
1. We explained (illustrated) the origin, history, classification and mechanism (effect) of Moxa Combustion.
2. The study of standardization plan of Moxa Combustion for popularization.
The thermal stimulation of Moxa Combustion was decided the characteristic pattern of combustion temperature by moxa burning and that makes a measure to grasp the effective action of Moxa Combustion upon human body. Thereupon it is necessary to continue further studies by analyzing the characteristic pattern of combustion temperature by moxa burning and there clinical effects in practice.
3. The usefulness of Moxa Combustion.
The therapeutic effect of Moxa Combustion are hematopoiesis (increase the blood), analgesic function, increase the immunity, antioxidant activity, diuretic action, control of hormone (endocrine gland), suppression of carcinogenesis, increase the self involution (natural healing), decrease of GOT/GPT, glucose, cholesterol level.

Primary intracranial yolk sac tumor usually arises in the pineal or suprasellar area and shows poor prognosis. Several children with primary yolk sac tumor in the cerebellum have been reported in the literature, and none of these survived beyond 30 months. We report a case of primary yolk sac tumor in the cerebellum showing longer survival with intensive multimodal combined therapy using surgery, preirradiation chemotherapy, and irradiation.

We report a case of pituitary apoplexy resulting in right internal carotid artery occlusion accompanied by hemiplegia and lethargy. A 43-yr-old man presented with a sudden onset of severe headache, visual disturbance and left hemiplegia. Investigations revealed a nodular mass, located in the sella and suprasellar portion and accompanied by compression of the optic chiasm. The mass compressed the bilateral cavernous sinuses, resulting in the obliteration of the cavernous portion of the right internal carotid artery. A border zone infarct in the right fronto-parietal region was found. Transsphenoidal tumor decompression following conservative therapy with fluid replacement and steroids was performed. Pathological examination revealed an almost completely infarcted pituitary adenoma. The patient's vision improved immediately after the decompression, and the motor weakness improved to grade IV+ within six months after the operation. Pituitary apoplexy resulting in internal carotid artery occlusion is rare. However, clinicians should be aware of the possibility and the appropriate management of such an occurrence.

OBJECTIVE: Temozolomide is a novel oral alkylating agent, which has been reported to be effective in treating patients with recurrent malignant gliomas. This study report an analysis of the activity and toxicity of temozolomide as second-line therapy for patients with recurrent and progressive malignant gliomas after surgery and standard radiation therapy with or without chemotherapy. METHODS: Twenty patients with malignant gliomas of which thirteen(65%) had glioblastoma multiforme(GBM), five(25%) with anaplastic astrocytoma(AA), and two(10%) with anaplastic oligodendroglioma(AO) were enrolled in this study. They had been treated in our institution since July, 2000 and had been previously irradiated with or without chemotherapy. For the patients with recurrent and progressive disease, temozolomide(150-200mg/m2/d x5 days) was administered every 28 days until the progression of the tumor or toxicity developed. RESULTS: The median number of treatment cycles was 3(total 86). Of the 20 patients, 2(10%) achieved a complete response(CR), 5(25%) achieved a partial response(PR), 5(25%) had stable disease(SD), and 8(40%) had progressive disease(PD). One patient achieved a CR, 3 patients achieved a PR, 2 patients had SD and 7 patients had PD in GBM, and 1 patient achieved a CR, 2 patients achieved a PR, 3 patients had SD, 1 patient had PD in the non-GBM patients. Median progression free survival(PFS) was 8 weeks in GBM and 22 weeks in the non-GBM patients. No hematological toxicity greater than grade 2 was observed, and hepatotoxicity of grade 2 was encountered in 1(5%) patient. CONCLUSION: Temozolomide demonstrate moderate activity in recurrent and progressive malignant brain tumors, and the response rate and PFS were better in the non-GBM tumors than in the GBM tumors. The treatment is well tolerated without any serious toxicity.
