INTRODUCTION: The number of passengers using aircraft is steadily increasing with the improvement in the air transport business. It requires the investment both in materials and human resources for commercial aircrew members to be able to accomplish their tasks of aircraft safety. Therefore, the aircrew members are required to maintain and improve their mental and physical states to an optimal condition. It is also very important to periodically evaluate a physical condition, which is essential to flight safety. METHODS: In this study, each of a total of 89 out of a population of 278 korea aircrew members over 50 were examined in three aspects: blood lipids, maximal oxygen consumption, and bone density. The examinee were divided into two groups (HDL-C high group and HDL-C low group) and three parameters described above were compared between two groups. RESULTS: The results were as follows: (1) TC and LDL-C were significantly higher(p<0.05), and HDL-C, TG and TC/HDL were significantly lower in HDL-C High group than HDL-C Low group (p<0.01). (2) The maximal oxygen consumption was significantly higher in HDL-C high group (p<0.05). (3) The bone density of lumbar spine was significantly higher in HDL-C high group (p<0.01). (4) VO2max were significant (P< .05) correlate to HDL-C. CONCLUSION: On the basis of the study, an aerobic exercise which helps in improving the maximal oxygen consumption and cardiopulmonary function is considered to be essential for aircrew members to maintain physical conditions for their tasks, and it is desirable to develop more effective aerobic exercise programs.

We report a case of ciliated hepatic foregut cyst which was incidentally found in a 64 year-old man. The cyst, 6 cm in diameter, was unilocular, solitary and was located in the medial segment of left lobe, just below the Glisson's capsule. Microscopically, the cyst wall consisted of 4 layers; pseudostratified ciliated columnar epithelium, subepithelial loose connective tissue, smooth muscle bundles and an outermost fibrous capsule. Although cartilage or subepithelial sero-mucous glands were absent, the morphologic features of the cyst correspond with those of an incomplete form of brochogenic cyst.

The fibrous pseudotumor arising from testicular albuginea in child is very rare benign tumor We experienced a case of this tumor in 6 year old boy who present with painless and nontender scrotal mass, which was movable on palpation. It was a hyperechoic lesion with calcification and had unclear relationship with testis in ultrasonography. Orchiectomy was performed after clamping of spermatic cord due to possibility of malignancy. The excised mass was 2.2xl.5cm sized, ovoid, white-yellowish, had a short stalk arising from testicular albuginea and showed whorled pattern in cut section. Microscopically, abundant collagenous fiber, proliferative fibroblast and calcification were noted.

PURPOSE: Convulsive status epilepticus(SE) is a serious, life-threatening neurological condition that requires immediate treatment to avoid significant morbidity and mortality. Despite improvements in the diagnosis and treatment of SE in the last two decades, SE in young infancy is still associated with high morbidity and mortality. Thus, understanding the varied etiology and clinical presentation and prognosis of SE is very important for improving the methods of evaluation and treatment of this major neurological condition. METHODS: Eighty-eight cases with 53 who have been admitted to the Department of Pediatrics, Fatima Hospital during the period of July, 1992 to June, 1997 were included. We described age distribution, etiologic classification according to age, seizure type, neurologic outcome, recurrence of SE and epileptic seizure. RESULTS: SE was frequent in young infant less than 3 years of age. Major etiology of SE was acute symptomatic(34.1%) and febrile(31.8%). In the seizure type, the majority(92.1%) was generalized convulsive, many cases(69.3%) of SE were first seizures. The neurologic sequelae were found in 15.9% and mortality rate in 5.7%. The neurologic sequelae and mortality were higher in acute symptomatic. In sixty-three follow-up cases, eleven cases were epileptic seizure, eight cases were recurred SE and two cases were recurred febrile SE. CONCLUSION: SE is a life-threatening neurological condition and occurrs mostly in young infants less than 3 years of age. It requires immediate detection of etiology in SE and aggressive treatment for reducing mortality and morbidity rates.

The precise nature of the underlying disturbance responsible for TTP is unknown, but recent work suggests that abnormalities of sodium channels play an important role. There are only a few electrophysiologic studies reported during an attack of paralysis of TTP and the electrophysiologic studies during paralytic attack in our two patients showed the following results, different only in severity. 1.Nerve conduction studies were normal in all the tested sensory nerves. Motor nerves showed normal conduction velocities, but low amplitudes of CMAPs except for median nerve. 2.Needle EMG showed markedly decreased insertional activities, and lowamplitude, short-duration, and polyphasic MUAPS, The recruitment patterns on maximal efforts were markedly reduced. There were no spontaneous activities. 3.Repetitive nerve stimulation of ulnar nerve showed significant incremental responses on digiti quinti muscle, marked during the early phase of stimulation. The degree of incremental responses was proportional to the frequency of stimulation.
