In September 1998, a case of nosocomial cutaneous myiasis caused by Lucilia sericata (Meigen, 1826) in a 77-year-old male was found. The patient had been receiving partial maxillectomy due to the presence of malignant tumor on premaxilla. This is the first verified case involving Lucilia sericata in Taegu, Korea. In the present paper, the salient morphological features of the third instar larvae involved have been studied.

We report a case of tracheopathia osteoplastica(TO) that.involvedboth larynx and tracheobronchus. On CTscans, the laryngeal and tracheobronchial cartilages were thickened with irregular calcification. Multiple nodules with or without calcification were seen protruding into the lumen from the anterior and lateral walls.

In mammal, lots of follicles start simultaneously their growth but only a few oocytes are ovulated in every sexual cycles. Most of matured and grown oocytes are destined to degenerate by atresia. However, the molecular and physiological mechanisms are not elucidated yet. The present study was designed to establish an induction method of follicular atresia with ketamine or pentobarbitone and evaluate the effect of these anesthetics on oocyte maturation and granulosa cell apoptosis of the mouse ovarian follicle. The percentages of degenerated oocyte and apoptotic granulosa cell in ketamine treated groups were significantly higher than that in controls (58.9% vs 33.5%, p<0.01, degeneration; 44.9% vs 26.6%, p<0.01, apotosis). Futhermore, it was revealed that the concentrations of progesterone in both groups were markedly higher than that in control. In conclusion, it is considered that ketamine induce an atresia as pentobarbitone, and may be useful for inducing follicular atresia.

31 cases of the trochanteric fractures were treated at the Department of Orthopedic Surgery, Chosun University Hospital, from Jan. 1975 to Dec. 1978 and the following results were obtained. 1. The sex ratio was 3:2 (male to female). 18 cases were in man, with the peak age at the 4th decade and 5th decade and 13 cases were in woman over the 6th decade. 2. The most common causes of the trochanteric fractures were traffic accident or fall in man and slipping in woman. 3. The features of the trochanteric fractures were mostly unstable type (60%) and 16 cases in the right hip (52%) and 15 cases in the left hip (48%). 4. Dimon-Hughston method and Wayne-Country method were used to the unstable fractures and anatomical reduction to the stable fracture was maintained by inserting the S-P nail, Jewett nail and Mclaughlin nail. 5. Post-operative cast immobilization was applled until clinical union was oftained on the fracture site and early weight bearlng was carried out for the acceleration of the bony union. 6. Complications were found in 50% of the group treated by conservative method, while it occurred in 21.7% of the group treated surgically.

OBJECTIVE: Our purpose was to compare the expression of endothelial nitric oxide synthase in the placenta and umbilical cord of preeclamptic placenta with that of the normotensive placenta. METHOD: We compared placental endothelial nitric oxide synthase expression in preeclamptic (n=5) with in normal (n=5) pregnancies. Frozen sections of umbilical cords, chorionic plate vessels, and terminal villi were immunostained with a monoclonal endothelial nitric oxide synthase antibody. RESULTS: The age revaled no difference between control (28.1+4.2 years). and study group (26.1+4.7 years). The gestational age was statistically different between control (38.9+1.7 weeks) and study group (34.9+3.5 weeks). The neonatal body weight and placental weight were also statistically different between control (3060+528 g) and study group (2160 417 g). No difference in endothelial nitric oxide synthase immunostaining in the endothelium of the umbilical vessels and stem villous vessels was found between preeclamptic and normotensive pregnancies. In contrast, in the preeclamptic placental endothelial nitric oxide synthase immunostaining was seen in the terminal villous vessels. In the syncytiotrophoblast endothelial niric oxide synthase immunostaining appeared primary basal in location and diffuse in distribution in the preeclamptic placentas but primary apical in the normotensive placentas. CONCLUSION: Differences in endothelial nitric oxide synthase expression in terminal villous vessels and syncytiotrophblast may be a result of vascular alterations or damage that take place in the placenta in preeclampsia.
