The subependymal giant-cell astrocytoma, a key feature of the tuberous sclerosis complex, has been reported in patients without obvious features of this condition. The tumor is a rare cerebral glioma that characteristically arise in the wall of lateral ventricle and as an intraventricular mass, causing hydrocephalus by obstruction of the foramen of Monro. We experienced a case of tuberous sclerosis in 9-year-old male patient who presented typical clinical manifestations and cortical tuber, subependymal giant-cell astrocytoma developing with hydrocephalus. Diagnosis was confirmed by brain CT and MRI. We applied surgical resection to remove the mass. Brief review and related literatures were also presented.

One of the important functions of nervous system is to supply the information related to the injury. Therefore, for various kinds of injuries, to feel pain is thought to be the part of this important function. There are A-fiber (Type I AMHs, Type II AMHs) & C-fiber (CMHs) which respond to the mechanical & thermal stimuli as the nerve fibers of peripheral unit performing this function. The phenomena expressed to us by these stimuli are those reaction like the in- crease of heart rate and the elevation of blood pvessure by stimulation of the autonomic nervous system as well as pain. As it is, using these reactions which are the most popular parameter of pain expression during anesthesia, we make the depth of anesthesia deeper or use analgesics as adjuvants. In general, there are many kinds of analgesics for adjuvants of anesthesia or for elimination of postoperative pain. To compare the efficiency of those analgesics toward pain, the authors studied the inhibitory effects of analgesics on the increase of pulse rate and mean arterial pressure evoked by the thermal and mechanical stimulations in rats. We used the agents popularly used in nowadays 1) Tramadol HC1, known as a potent analgesics, 2) Nalbuphine, antagonist of opioids, 3) Meperidine and Morphine, opioids to com- pare the efficiency of hemodynamic augumentation by the thermal and mechanical stimulations with the control group. The results were as follows', 1) The inhibitory effects on the increase in pulse rate and mean arterial pressure evoked by the stimulations were in the decsing order of morphine, meperidine, nalbuphine, and tramadoL 2) The inhibitory effect of morphine on the incmnent of pulse rate and mean arterial pressme was evident. 3) Meperidine and nalbuphine, not so much potent as morphine in inhibitory also inhibit to a considerable degree. 4) In the case of tramadol, the increament of pulse rate evoked by the stimulations were inhibited to some extent, but it was proven not to inhibit the elevation of mean arterial pressure.

Pheochromocytoma is the cause of hypertension in 0.1% of the hypertencive patits, and in 10% of these cases, the tumor is bilateral. Therefore bilateral pheochromocytoma is very rare. The following is a report of the anesthetic methods employed in the surgical management of a case of bilateral pheochromocytoma which was performed in stages at PNUH, between June 4th and June 12, 1986. The staged operation reduced the instability of the vital signs caused by concurrent manipulation of the bilateral pheochromoytoma and facilitated tumor removal.

The purpose of this clinical study was to evaluate the postoperative pulmonary function and ventilatory reserve in patients over 60 years of age. The author analysed 40 anesthetic patients who underwent abdominal surgery at the Department of Anesthesiology of Pusan National Universtiy Hospital from Mach 1, 1987 through July 31, 1988. Only those patients who have had normal or nearly normal cardiopulmonary function were selected and those who developed postoperative pulmonary complications were excluded from the study. The results were as follows: 1) On the first postoperative day, the FVC of the upper abdominal surgery group was 44% of the preoperative value, 2.84+/-0.68 1/sec, and that of the lower abdominal surgery group was 64% of the preoperative value, 2.84+/-0.36 1/sec, (p<0.001). 2) On the first postoperative day, the FEVI of the upper abdominal surgery group was 37% of the preoperative value, 2.24+/-0.64 1/sec, and that of the lower abdominal surgery group was 51% of the preoperative value, 2.43+/-0.31 1/sec, (p<0..01). 3) On the first postoperative day, the MMEF of the upper abdominal surgery group was 55% of the preoperative value, 2.50+/-0.36 1/sec, and that of the lower abdominal surgery group was 75% of the preoperative value, 2.55+/-0.71 1/sec, (p<0.001). 4) The preoperative FEVI/FVC ratio of the upper abdominal surgery group was 79%, and that of the lower abdominal surgery group was 84%. In the postoperative period, there were no significant differences between the upper and lower abdominal surgery group. 5) In the upper and lower abdominal surgery group, postoperative pH and PaCO2 values were found to be changed insignificantly. 6) In the upper and lower abdominal surgery groups, postoperative PaO2 values were found to be decreased significantly(p<0.05).

This study examined the protective effect of dexamethansone following bilateral forebrain ischemia in a rat model of two-vessel occlusion. Twenty rats were subjected to dexamethasone (1 mg/kg intravenously) before bilateral common carotid artery occlusion for 10 minutes. Carotid artery blood flow was restored and the rats were terminated by a perfusion-fixation method after 7 days. Ten minutes of two-vessel occlusion produced cellular ischemic change in the cerebral hemispheres of most rats. This region was studied mainly with light microscope, and it was noticed that the CA 1 neuron in the hippocampus is the most vulnerable to ischemia. Ischemic neuronal damage was graded in accordance with conventional neuropathological criteria. The grade had no statistical significance.
