It has been known that most patients with Korean Hemorrhagic Fever (KHF) were recovered without any significant renal complication. But several cases of renal hypertension, chronic pyelonephritis, and chronic renal failure after KHF have been reported. Recently, we experienced one case of chronic pyelonephritis as a sequela of KHF, which has been diagnosed at the 78th month of illness. This case showed reduced thickness of renal parenchyme, small and irregular shaped kidney, focal loss of normal cupping of calyces, and accumulation of radiacontrast media at distal calyes by IVP. This case suggested that chronic pyelonephritis may develop as a sequela of KHF,

Midazolam maleate, a water soluble banzodiazepine unlike diazepam, was synthetized by Walser and Fryer in 1975. In order to ealuate the effectiveness as an induction agent for general anesthesia, 22 elective surgical patients belonging to ASA classification 1 and 2 were selected. And ten patients (male 7, female 3, average 33.5 years old) were induced with midazolam maleate 0.2mg/kg and twelve patients (mdale 7, female 5, average 32.5 years old) with diazepam 0.3mg/kg. The results were summarized as follows. 1) Anesthesia was induced in all of midazolam group by one intravenous injection, but only 6 patients of diazepam group could induced by one injection and the other 6 patients needed 2 or more injections. 2) The changes of blood pressure and pulse rate after induction and intubation were almost similar in the two groups, but greater individual variation was seen in diazepam group. 3) A buring sensation following intravenous injection was noted in 11 cases of diazepam group, but none in midazolam group and no phlebitis in either group. From the above results, diazepam and midazolam are almost similar in nature but midazolam is definitely effective as an induction agent and has less side effects. Therefore midazolam maleate is regarded as a more effective agent than diazepam as an induction for general anesthesia.

Taxonomic review of the five flyingfishes, Parexocoetus mento (Valenciennes), Cheilopogon agoo (Temminck et Schlegel), Cheilopogon heterurus doederleini (Steindachner), Cheilopogon cyanopterus (Valenciennes), Hirundichthys oxycephalus (Bleeker) were carried out based on samples collected from the South sea and around sea of Jeju Island of Korea from 1996 to 1998. Parexocoetus mento (Valenciennes) and Cheilopogon cyanopterus (Valenciennes) were revealed as the unrecorded species in Korea, which were named as "Men-to-hwang-nal-chi" and "Ki-geom-nal-chi" respectively. Parexocoetus mento is differed from P. barchypterus in having no chin barbels in juveniles, and Cheilopogon cyanopterus is distinguished from C. agoo in the branched form of pectoral fin rays and from C. heterurus doederleini in the numbers of the dorsal fin ray and the color of pectoral fins.

The lung is the most common site of metastasis of extrapulmonary malignant tumor. According to past reports, metastatic cancer of the lung has been found in about 2% of all patients at autopsy. But these days, a diagnosis of endobronchial metastatic cancer utilizing bronchoscopy only is not easy. Thus we need other means of gathering more informaction, such as past history, discovery of other metastatic sites, and pathologic findings with special staining and electronmicroscope, especially in cases of poorly differentiated adenocarcinoma and epidermoid cancer, which are common types of primary lung cancer. We present 5 cases of endobronchial metastatic cancer. We found endobronchial metastatic cancer 2 cases of cervix cancer (epidermoid, adenocarcinoma), 1 case of colon cancer (adenocarcinoma), hypernephroma (renal cell carcinoma), and bladder cancer (transitional cell carcinoma). Since it was impossiole to diagnose the metastatic adenocarcinoma from the cervix only with lightmicroscopic findings, we could use past history and unusual radiologic and bronchoscopic findings which was thought to be the specific endoscopic finding of metastic endobronchial cancer. The interval between the diagnosis of the primary cancer and endobronchial metastatic cancer was 25.7 months. In the future, development of immunohistochemistry, monoclonal antibody, and molecular biologic techniques will give us diagnostic clue for differential diagnosis of metastatic endobronchial cancer from primary bronchogenic lung cancer.

An imaginative innovation to shorten hospital stays as a means to reduce patient charges, is out-patient surgery. This procedure also minimized the inconvenience and disruption of the family unit, reduced the opportunities for cross-infection, and freed hospifal beds for the more serriously ill patienta Since the concept of out-patient surgical service was organized, managed, and performed in the Hanyang Medieal Center, we had experience of 132 ambulatory anesthetics during the last two years (from Jan. 1974. to Dec. 1975 ). The results are summarized as follower 1. Preanesthetic examination should be routinely cheeked with Hb., Hct., urinalysis and chest x-ray. 2. Premedication should be administered preanesthetically, atropine sulfate intravenously. 3. ASA class 1 patients should be rhnsen fnr short (less than 1 hour) procedures. 4. Anesthesia is induced with Epontol+S.C.C. and maintained with Halothane+N2O+O2. 5. We suggest that ambulatory anesthesia should be more carefully planned, organized, and managed.

A new type of Si diaphragm was fabricated using Si-wafer direct bonding and two-step electrochemical etch-stopping methods. Using the new diaphragm structure in mechanical sensors, more precise control of cavity depth and diaphragm thickness was achievable. Also, the propagation of the stress, which was generated near the bonding interface, to the surface can be avoided. Finally, a piezoresistive-type Si pressure sensor was fabricated utilizing the diaphragm and a digital pressure gauge, which can display units of pressure, was realized.

In this study, the radiation monitoring system using CsI(TI) scintillation counter is developed for the measurement of radiation distribution in the field of high dose level. When the inner diameter of collimator is 8 mm, we have realized the optimum detecting efficiency and spatial resolution. At that time, the position resolution was 10 cm at 1 m from the system. And experimental results indicated that the energy resolution of the system were 10 % for 662 keV of Cs-137, 7.6 % for 1.17 MeV of Co-60, and 5.8 % for 1.33 MeV of Co-60. Also, we have shown that the real radiation distribution images may be obtained by our measurement system.

Phenochromocytoma is a catecholamine-secreting tumor, most of which grow at the adrenal gland. About 109p Of pheochromocytomas are detected at the extra-adrenal chromaffine tissues and are called paraganglioma. The main symptoms of pheochromacytoma include hypertension, headache, palpitation, and sweating. Gastrointestinal symptoms such as abdominal pain, constipation, and vomiting are found in 20∼40% of patients with pheochromocytoma, but these are usually overlooked because of the severe, prominant cardiovascular symptoms. Intestinal pseudo-obstruction without hypertension in pheochromocytoma is very rarely found. It is caused by the decreased motility of the intestine and the over-contraction of the intestinal sphincter, which are caused by the unbalanced activation of α-and β-adrenal receptors. It can be hypothesized that catecholamine receptors in the cardiovascular system are down-regulated or desensitized, but those in the intestine remain intact. We report herein a case of pheochromocytoma in which intestinal pseudo-obstruction was the main presenting clinical manifestation. Symptoms of intestinal pseudo-obstruction were completely relieved by administration of phenoxybenzamine, an α-receptor blocker, and excisional surgery.
