Intestinal capillariasis is caused by a small trichurid nematode, Capillaria philippinensis, which infects freshwater fish as intermediate hosts and subsequently fish eating birds as definitive hosts. It has occurred in areas such as the Philippines and Thailand where people eat raw fish. We report an imported case of intestinal capillariasis in a 31-year-old Korean man who lived in Saipan for ten years. He suffered from diarrhea with weight loss, abdominal distension, and pitting edema in the lower extremities for two years. He ate raw freshwater fish in the Saipan 2 years ago. The diagnosis was confirmed by jejunal biopsy. Flat mucosal surface without villi contained sections of numerous round worms with stichosome, larvae, and eggs which were identified as Capillaria philippinensis. The patient was successfully treated with albendazole.

In accordance with the development of EEG and polysomnography in the field of sleep research, the sleep onset period (SOP) between wakefulness and sleep has been considered an important part for understanding the physiology of sleep. SOP in the transition from wakefulness to sleep is a gradual process integrating various viewpoints such as behavior, EEG, physiology and subjective report. Particularly, based on understanding of EEG changes during sleep, SOP has been regarded as a pattern of topographical change in specific frequency and specific state in EEG. Studies on quantitative EEG (qEEG) and event-related potential (ERP) have suggested that SOP shows the changes of functional coordination at the specific cortical areas in qEEG and the changes of regular patterns in response to environmental stimulation in ERP. The development of sleep EEG and topographic mapping of EEG is expected to integrate various viewpoints of SOP and clarify the neurophysiologic mechanism of SOP further.

Utrasonic evaluation has been suggested as a screening method for early ovarian cancer. This study was designed to evaluate the aceuracy of pelvic ultraesound to measure the ovarian volume as the preliminary study. The ovarian volume me ured. by ultrasound was compared with findings at. surgery. Subjects far this investigation were 25 menstruating patients and 12 climacteric patients who were scheduled for gynecologic surgery chiefly unrelated to adnexal masses. The mean nf ovarian volume with menstruating patients was 5.7+/-5.9cm3 and that of climacteric patients was 2.5+/-l.3cm3(P<0.01). The eorrelation coefficient between the ovarian volurne measurement made by two examiners was 0.80. The correlation coeffieient between the ovarian volume measured by transvaginai ultrasonography and ovarian volume at laparotomy was 0. 37 and poor, The ll ovaries(52%) among the 24 ovaries of 12 climacteric tients were not visualized. So, this study suggested that the ovarian volume measurements af the postmenopauml by transvaginal ultrasonograpy was not simple and demanded the skill and laboraus training.

Occasionally, a bony spine of variable size, the supracondylar process, projects distally from the anteromedial surface about 5cm proximal to the medial epicondyle, to which it is joined by a band of fibrous tissue. It was found in one per cent of living white subjects and less often in the colored races; only in rare instances it is associated with clinical signs, usually median nerve neuralgia. Here, we reported a case of incidental finding of supracondylar process without a definite symptom.

Of the shoulder syndromes, acute calcific tendinitis of the rotator cuff is the least difficult to differentiate, for the mechanical and inflammatory aspects combine to produce a picture of severe, and localized pain which presents in obvious distress, splinting the affected shoulder by holding the arm to his side. The radiologic picture corresponds poorly to the clinical picture, with visible calcium deposits ranging from thin crescents to large fluffy amorphous masses. Acute calcific tendinitis is a self-limited process with a natural history of 6 to 14 days. Relief is dramatic when the inflammatory and mechanical cycle is broken, but the potential remains for exacerbation as for more serious sequellae such as adhesive capsulitis. We expereinced 5 lesions of calcific tendinitis in supraspinatus tendon treated by surgical removal in 4 lesions and by conservative measure in one lesion.

PURPOSE: To evaluate ultrasonographic findings and usefulness in the diagnosis of breast diseases during pregnancy and lactati ng period. METHODS AND MATERIALS: The authors evaluated the ultrasonographic findings of 18 breast diseases during pregnancy and lactation retrospectively. The ultrasonographic examinations were performed with linear-array 5 MHz transducer (ATL). Final diagnoses were obtained by the excisional biopsy, fine needle aspiration and clinical follow-up. RESULTS: Total 18 cases of breast diseases were consisted of 8 cases of galactocele, 4 cases of fibroadenoma, 3 cases of axillary accessory breast, 2 cases of lactating adenoma, and I case of phylloides tumor. The ultrasonographic findings of the above breast diseases were valuable in the diagnosis and therapeutic planning. CONCLUSION: Ultrasonography is the initial and useful method of diagnosing breast diseases during pregnancy and lactating period.

OBJECTIVES: This study was to investigate the fertilization rate after intracytoplasmic sperm injection (ICSI) or partial zona dissection (PZD) of human and hamster sperm into hamster oocyte in in vitro fertilization (IVF). In addition, the possibility of clinical application was evaluated by the comparison of usefulness and difference of these method. MATERIALS AND METHODS: Hamster immature oocytes were obtained from oviducts superovulated by PMSG and hCG, and hamster sperms were obtained from epididymis. The freezed human sperms were thawed before use. Fertilization were confirmed by two pronuclei, one pronucleus, swollen sperm head or/and two polar bodies at 7~8 hour after ICSI or PZD. RESULTS: The fertilization rates after ICSI and PZD of human sperm to hamster oocyte were 3.6%, 64.2%, 73.6%, and 55.6% for negative control, positive control, ICSI, and PZD respectively, suggesting that ICSI only showed improved fertilization rate (p<0.01). The fertilization rates after ICSI and PZD of hamster sperm to hamster oocyte were 11.1%, 51.2%, 39.6%, and 72.7% for negative control, positive control, ICSI, and PZD respectively, suggesting that PZD only showed improved fertilization rate (p<0.01). PZD showed significantly higher fertilization rate than ICSI (p<0.05). CONCLUSIONS: As for the fertilization rate by ICSI and PZD using hamster oocyte in IVF, ICSI technique was considered to be more useful for human sperm and PZD technique for hamster sperm. Therefore, ICSI technique was considered more appropriate for experimental application using human sperm and hamster oocyte.

OBJECTIVES: This study was carried out to evaluate the effects of embryonic stage, cryoprotectant, and freezing-thawing method on the rates of survival and development of the cryopreserved mouse early embryo and finally to establish the cryopreservation method of surplus embryos obtained during assisted reproductive technology (ART). MATERIALS AND METHODS: Two to eight cell embryos were obtained from oviducts of mated F1 hybrid female mice superovulated by pregnant mare's serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG). Two-step 1,2-propanediol (PROH), dimethylsulfoxide (DMSO) and 4-step PROH, DMSO were used as cryoprotectant and dehydration and rehydration method of embryos, and slow- cooling or rapid-cooling method was used as frozen program. The survival rates of embryos were measured after thawing and rehydration, and the developmental rates of embryos were compared and observed during culturing embryos for 24, 48, 72, 96 hrs. RESULTS: As for the survival and development rates of embryos according to embryonic stage, the survival rate of 2 cell stage in PROH and DMSO was significantly higher than 4-8 cell (64.5% versus 62.1%, 79.7% versus 73.2%) (p<0.01, p<0.01), but the development rates of 4-8 cell embryos in PROH and DMSO were significantly higher than 2 cell embryos for whole culture period (p<0.01) and the development rates of 4-8 cell embryos in PROH were significantly higher than 2 cell embryos in DMSO (p<0.01). As for the survival and development rates of embryos according to cryoprotectant, the survival rate of 2 cell embryo in DMSO was significantly higher than that in PROH (74.4% versus 64.5%) (p<0.01), whereas the development rate of embryos was not differ till 24 hrs. The development rate from morular to hatching blastocyst, however, was significantly higher in PROH than in DMSO during 48 hr (p<0.01). The survival rate of 4-8 cell embryo was 62.1% in PROH and 73.2% in DMSO. The development rates of embryo in PROH were significantly higher for whole culture periods (p<0.01, 0.05). In respect to the effect of freezing and thawing program on the survival and development rates of embryos, method of slow cooling and rapid thawing was more effective than that of rapid cooling and rapid thawing. CONCLUSIONS: The survival rate of embryo in 2 cell stage was higher than in 4-8 cell stage, and PROH appears more effective cryoprotectant than DMSO because PROH showed better development rates of embryos in 2 and 4-8 cell stage. Moreover, slow cooling and rapid thawing method was considered as the best cryopreservation program.

This study was performed to investigate the stimulating effect on oocyte maturation and cumulus cell expansion in TC199 media by human cord serum (HCS) supplementation. Immature mouse oocyte cumulus complexes (OCCs) were cultured in TC199 media supplemented with bovine serum albumin (BSA), HCS and human chorionic gonadotropin (hCG) instead of luteinizing hormone (LH) respectively, and the expression of cumulus expansion and oocyte maturation were observed. After 4hr and 24hr culture with or without OCCs, media containing 0.4% BSA, 10% HCS and 10 lU hCG respectively were collected and analyzed for changing concentrations of estradiol (E2), progesterone(P4), testosterone(T), and PGF2. There were no elevation of E2, T, and PGF2 by OCCs culture, but minute elevation of P4 level by 24hr OCCs culture in hCG supplementation (p=0.048). The stimulating pattern of cumulus expansion of OCCs by HCS and hCG supplementation was similar to our previously report using Ham's F-10 media, however oocyte maturation rates after 24hr OCCs culture in all media were increased by 20~30% compared to Ham's F-10 media. These results suggest that LH in HCS induce cumulus expansion probably by P4 secretion of OCCs, and TC199 is efficient media for immature mouse oocyte maturation.
