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.

OBJECTIVES: Recently, recombinant FSH (rFSH) has been manufactured using a Chinese hamster ovary cell line transfected with the gene encoding human FSH. Both rFSH and urinary gonadotropin (uFSH) could be used for controlled ovarian hyperstimulation (COH). However, uFSH implies a number of disadvantages, such as batch-to-batch inconsistency, no absolute source control, dependence on large amounts of urine, low specific activity, and low purity. The purpose of this study was to evaluate the efficacy of rFSH in human IVF-ET program. MATERIALS AND METHODS: A total of 508 infertile women was enrolled in this study. They are classified into rFSH group (n=177) or uFSH group (n=331), and all of them were matched by age and cause of infertility in same period. The Puregon(R) (Organon, Holland) was used as rFSH, and the Metrodin-HP(R) (Serono, Switzeland) and Humegon(R) (Organon, Holland) was used as uFSH. We subdivided the patients into three age groups. The outcomes of IVF-ET program were analyzed using the statistical package for social sciences (SPSS). RESULTS: There was no significant differences in the level of estradiol on hCG injection day, the numbers of retrieved oocytes, matured oocytes, fertilized oocytes, transferred embryos, frozen embryos between the two groups. The total dose (IU) of gonadotropin for COH was significantly lower in the rFSH group compared to uFSH group (1339+/-5491.1 vs 2527.8+/-1075.2 IU, p<0.001). Clinical pregnancy rate per embryo transfer in the rFSH group showed increasing tendency, compared to the uFSH group, but there was no statistical significance (35.2% vs 29.3%). Our results demonstrated that the relative efficiency of rFSH compared with uFSH is higher in older patients. CONCLUSIONS: The ovarian stimulatory effect and clinical outcome of recombinant FSH was similar to that of the urinary gonadotropin. The IVF-ET cycles with significantly lower dose of gonadotropin in rFSH group showed comparable results. Therefore, we suggest that recombinant FSH is more potent and effective than urinary gonadotropin.

PURPOSE: It has been customary to perform brain ultrasonogram (brain US) for the early detection of intraventricular hemorrhage (IVH) during intensive care of neonates. On the other hand magnetic resonance imaging (MRI) has been greatly restrictioned due to its complicated procedures. This study was conducted to identify changes in neonates' brain structure and to gain basic data for the long-term follow-up of neurologic sequelae in the future. For this purpose, the findings obtained from both brain US performed within one postnatal week and MRI at the time of discharge were compared and analysed. METHODS: Brain US within one postnatal week and MRI at discharge were carried out on 67 neonates who were discharged from the neonatal intensive care unit of Fatima Hospital from July 01, 1996 to June 30, 1998. We compared and analysed IVH found in the brain US, and focal parenchymal hemorrhage, periventricular leukomalacia (PVL), basal ganglia hemorrhage, and encephalomalacia revealed the MRI performed at discharge. RESULTS: It was found that out of 67 cases from the brain US, there were 13 with IVH of Grade l & ll, 11 with IVH of Grade lll or higher, one with focal parenchymal hemorrhage, and three with PVL. Also the MRI found seven with focal parenchymal hemorrhage, one with basal ganglia hemorrhage, six with PVL, three with encephalomalacia, and one with ventricular dilatation. CONCLUSION: For infants with IVH of Grade lll or higher, MRI performed at discharge is considered to be very useful in identifying structural parenchymal abnormality and the presence or absence of its associated lesions as well as in carrying out long-term follow-up.
