Pleomorphic adenoma presenting as primary lesion of the bronchus is very rarely encountered, and in our knowledge only 6 cases have been reported in the literature of the western world, and no case report has been published in Korea. Currently, we experienced a case of bronchial pleomorphic adenoma occuring in a 38 years old woman. On X-ray examination, hazy density in the right upper lobe and emphysematous change in the right lower lobe were noted. A right pneumonectomy was done under bronchoscopic diagnosis of bronchial adeoma. The pathologic examination of the present case showed a polypoid endobronchial tumor, 1.4 x 1.1 cm (with extraluminal portion, 2.2 x 1.7 cm) in the right upper bronchus. The microscopic examination revealed a pleomorphic adenoma showing same morphology as those found in the salivary gland. This case, therefore, was believed to be a genuine example of bronchial pleomorphic adenoma of salivary gland type. We compared this case with 6 cases in the literature.

BACKGROUND AND OBJECTIVES: The purpose of this research was to evaluate physiological significances of expression of immediate early gene proteins in the vestibular nuclear complex by change of arterial pressure (AP) in adult Sprague-Dawley rats. MATERIALS AND METHOD: Record AP and inject either sodium nitroprusside (SNP) or phenylnephrine to change AP. Either fast or slow removal of blood from the femoral artery was made to induce different rapidity in reduction of AP. Blood supply to the inner ear was temporally blocked by clamping anterior inferior cerebellar artery (AICA). Immunohistochemical staining and image analysis for cFos, FosB, Krox, and JunB proteins were performed 2, 6, 12 hours after change of AP. RESULTS: The selective expression of cFos protein was observed in the medial vestibular nucleus (MVN) following reduction of AP. The number of cFos positive neurons peaked at 2 hours and then rapidly reduced, returning to the normal value 24 hours after SNP injection. And cFos protein expression was also well correlated with that of AP reduction at 2 hours of SNP injection. The rapid falling of AP caused a significant expression of cFos protein but slow withdrawal of blood did a minimal change of cFos protein expression. In addition, there was a significant expression of cFos protein following the increase of AP by single injection of phenylnephrine. Unilateral occlusion of AICA resulted in the significant expression of cFos protein in bilateral MVN. Furthermore, bilateral ablation of vestibular endorgans resulted in significant reduction of cFos expression by AICA occlusion in MVN. CONCLUSION: These results suggest that cFos protein is a marker for neuronal excitation in vestibular complex in response to rapid changes in the arterial blood pressure and that medial vestibular nuclei plays an important role in signaling the process of cardiovascular information coming from the peripheral vestibular apparatus.

The increasingly successful results of hair restoration surgery in the last years have developed the interest and the confidence of patients and it is the most frequently performed esthetic surgery among male patients. Currently, various kinds of techniques for hair restoration surgery including hair transplantation, scalp reduction, and scalp flaps are performed in our clinic. Among these, hair transplantation is the basic and the most popular procedure, which can be performed not only by itself but also in conjunction with other procedures. 123 consecutive cases of hair transplantations were peformed from Jan. 1995 to Feb. 1996 for male pattern baldness, traumatic alopecia, and female pattern baldness under out patient base. The authors introduced a new classification for male pattern baldness, which are the type M, O, C, U, M-O, and C-O after alphabet to make simple and easy for clinical application. The ancillary procedures were scalp reduction, preauricular flap, and scalp expansion. An ellipsis of hair bearing scalp taken from the occipital area was sliced into slit-, mega-, mini-, and micro-grafts. The survival rate of the grafts was over 90% with minimal complications. This hair transplantation technique enabled us to achieve a good density and more natural looking hair with avoidance of cobble stoning and apparent scar.

OBJECTIVES: Cadmium (Cd), a toxic and non-essential metal, is recognized as a human carcinogen, which has a tendency to accumulate in the human body. The levels of Cd in renal cortex and liver are good indicators as an index of Cd exposure in the general population. In this study, we present an estimation of reference Cd levels in tissue (renal cortex and liver) and total body burden in the general population of Korea. MEDTHODS: Cd and zinc (Zn) were analyzed in renal cortex and liver from 254 autopsies (male : 188 cases, female : 66 cases) aged 0 to 87 years. RESULTS: Geometric mean concentration of Cd was 27.4 and 3.1 ua/g wet weight in renal cortex and liver, respectively. The level of Zn in renal cortex and liver was 35.4 and 42. 6 v/g wet weight, respectively. The result suggests that kidney is the target organ for Cd accumulation. The accumulation of Cd in renal cortex was age-dependent with a biphasic pattern. The level of Cd in renal cortex increased with age up to the fifties, and then leveled off thereafter. Based on the data, the regression model for Cd accumulation in renal cortex by age is predicted by : Log KCd = 0. 2325 + 0. 0553 Age 0. 0005 Age. The highest Cd accumulation in renal cortex of Koreans was estimated at 43. 3 ua/g wet weight at 50. 8 years old. In addition, the total Cd body burden by age was estimated by the following equation: Total Cd Body Burden = -4. 5948 + l. 2278 Age - 0. 0121 Age. The highest body burden of Cd was estimated at 26. 5 mg at age 50. 7 years in the Korean general population. The positive correlation between Zn and Cd was observed in renal cortex and liver. CONCLUSIONS: The level of Cd exposure in Korean was found to be lower than in Japanese, but same as or higher than in American and Europeans.

The laparoscopic cholecystectomy, performed for the first time in France in 1987, has been accepted as in many countries the method of choice when performing a cholecystectomy. The trend toward minimally invasive surgery has prompted general surgeons to try it instead of open cholecystectomy. We performed 1000 laparoscopic cholecystectomies at the Department of General Surgery of Eulji Medical College Hospital from January 1992 to April 1997. The outcome data have been analyzed retrospectively. Moreover, we have compared the case histories of 13 patients who received cholecystostomy with those of 43 patient who did not. We also present preliminary results for an interval laparoscopic cholecystectomy which was a preceded by percutaneous cholecystostomy. The results are as follows: 1) The mean age was 54.3 years ranging from 17 to 86; there were 402 males and 598 females. 2) Of the 1000 patients, 123 patients (12.3%) had a history of abdominal surgery. 3) More than half of the patients(560 patients, 56.0%) underwent operations within 6 months of the onset of symptoms. 4) A preoperative endoscopic retrograde cholecystoscopy was performed on 220 patients (22.0%), and of these, 93 patients received endoscopic sphincterotomies because of bile duct stones. 5) The majority of patients(744 patients, 74.4%) had laparoscopic cholecystectomies which lasted 40 minutes or less. 6) More than half (54%) of the removed gallbladders showed grade II inflammation. 7) Drains were used in 142 patients (14.2%). 8) Postoperative complications were encountered in 48 patients (4.8%). 9) Postoperative oral intake was resumed within 24 hours in most patients. 10) Most patients(854 patients, 85.4%) were discharged within 3 days of the operation. 11) The pathologic diagnosis was chronic nonspecific inflammation in most cases (823 cases, 82.3%). 12) The most common microorganism in the bile was E. coli. 13) Patients who received a cholecystostomy had many benefits: a shorter operation time, a low rate of open cholecystectomy, early oral intake. 14) For the 1160 patients who underwent a cholecystectomy during the same period, the rate of open cholecystectomy was 13.8%.
