Intramural implantation is among the rarest forms of ectopic pregnancy.Since the first description by Perli, 21 cases were reported in worldwide literatures.The pathologic criteria required for intramural pregnancy is that the product of conception is completely surrounded by uterine musculature and is separated from the uterine cavity and the fallopian tube or round ligament.The previous history of uterine injury or adenomyosis is known as possible etiology of intramural implantation. Because the early diagnosis is very difficult, most cases is found after onset of complication such as a uterine rupture or hemoperitoneum. We have recently experienced a case of intramural pregnancy diagnosed and treated by laparoscopy in a 9 weeks gestation nulliparous woman without previous history of uterine injury or disease, and report with a brief review of literatures.

Avulsion injury of the flexor digitorum profundus tendon from distal phalanx is considered as a rare injury. Accrording to the classification by Leddy and Pacter, this case is Type III, which is a large bony fragment retained by the tendon. The distal pulley prevents retraction beyond the middle phalanx. We are reporting a case with brief review of literatures.

To investigate whether the abnormal expression of matrix metalloproteinases(MMPs) in the aqueous humor may case the development of glaucoma, the activity of MMP in the aqueous humor of galucoma and cataract patients were measured and compared. Six primary open angle glaucoma(POAG), 2 chronic angle closureglaucoma(CACG), 2 normal tension glaucoma(NTG), and 14 cataract patients were enrolled. Aqueous humor of each patients were collected during surgery, and total protein concentration and activity of gelatinase A in the aqueous humor were measured by protein assay kit and zymography, respectively. Total protein concentration and gelatinase A activity of POAG patients were increased by 2.1 times and 3.9 times, respectively compared to those of cataract patients. However, there were no statistically significant changes in total protein concentration and gelatinase A activity of CACG and NTG patients compared to those of cataract patients. In conclusion, the development of POAG may be associated with the abnormal expression of MMP in the aqueous humor.

The shoulder injury was resulted from muscle imbalance between acceleration and deceleration during the throwing. The agonist-antagonist muscle strength relationship for throwing was formerly described as functional ratios of eccentric external rotator to concentric internal rotator moments and eccentric internal rotator to concentric external rotator moments. The purpose of this study was to measure the ratio of concentric and eccentric strength of the shoulder rotators by isokinetic muscle performance in Korean throwing college athletes for descriptive data. On 10 dominant shoulders of asymptomatic throwing college athletes applying Cybex II isokinetic dynamometer, concentric and eccentric muscle strength of the rotators were measured at the speed of 90degrees/s, 180degrees/s, 240degrees/s. Maximal torque ratio of the eccentric strength of the external rotator against the concentric strength of the internal rotator was 1.25, 1.13, 1.21 at the each speed. The functional external eccentric-to-internal concentric ratio was similar with previous published studies. There was no significant difference between each speed. Eccentric strength of the external rotator was higher than concentric strength of the internal rotator during internal and external rotation at all speeds. This functional assessment of strength testing that reflected the importance of eccentric external rotation strength for the dynamic shoulder joint stability during the throwing. Therefore, the increase of the eccentric strength of the external rotator would be helpful to prevent the shoulder injury and to treat for rehabilitation of injured shoulder.

A melanotic neuroectodermal tumor of infancy (MNTI) is a uncommon osteolytic pigmented neoplasm that primarily affects the jaws of newborn infants. Most patients (> 90%) present with the tumor in the first year of life. Approximately 65% form in the maxilla, 11% in the mandible, 5% in the brain and elsewhere. MNTI is normally benign, but up to 15% may recur and a few have metastasized. Approximately 200 cases of MNTI have been reported but only 2 of them presented as multifocal. A case of MNTI in a 7 month old boy was encountered. The chief complaint was maxillary anterior ridge swelling. The incisional biopsy findings were MNTI. Two months after the first operation, mild swelling of another site was observed. The infant was examined periodically since undergoing two procedures with no recurrence. This case demonstrates the possibility of a multicentric MNTI. We report a multicentric MNTI with a review of the relevant literature.

INTRODUCTION: To evaluate the skeletal stability after a bilateral sagittal split osteotomy (BSSO) setback of the mandible fixed with a biodegradable internal fixation device or metal internal fixation device. MATERIALS AND METHODS: Thirty consecutive patients underwent mandibular setback via BSSO. Fifteen patients were fixed with a biodegradable internal fixation device or metal internal fixation device respectively. Posteroanterior (PA) and lateral cephalograms were taken preoperatively and at two days, 5.5 months and 14.5 months postoperatively. The relevant skeletal points were traced and digitized to evaluate the skeletal changes postoperatively. The relapse rates were analyzed and compared statistically. RESULTS: There was no statistically significant differences in postoperative stability between the two groups.(P<0.05) CONCLUSION: The biodegradable internal fixation device may make an effective device alternative to a metal internal fixation device for setback BSSO.

PURPOSE: To identify novel proteins which bind to myocilin, using a yeast two-hybrid screening system. METHODS: A bait plasmid of myocilin was constructed, and then transformed into yeast AH109. The transformed yeast cells were mated with yeast Y187 containing human skeletal muscle cDNA library plasmids in 2 X YPD medium. Mated diploid yeasts were plated on synthetic dropout medium (SD/-Trp-Leu-His and SD/-Trp-Leu-His-Ade). The positive clones grown on the selective medium were amplified, sequenced, and analyzed using the database of GenBank. The expression of selected genes in trabecular meshwork (TM) cells was detected by RT-PCR. RESULTS: The expression of bait protein in yeast was confirmed by Western blot analysis. Extensive screening of a cDNA library led to the selection of twenty-four positive clones which represent eight genes, including six of cytoskeleton associated proteins such as alpha-actin, myosin regulatory light chain 2A, dynactin, syntrophin alpha1, microtubule associated protein 1B, and myosin binding protein C. CONCLUSIONS: Myocilin may interact with cytoskeleton associated proteins in TM cells. Further studies on their interactions will provide functional clues of myocilin.

OBJECTIVE: It is well known that X-ray induces follicular atresia, but the exact mechanism of atresia is not still unveiled completely. In addition, the role of macrophage related with clean-up the dead granulosa cells and other functions within the ovarian follicle is emphasized recently. The aim of this study is to assess the radiation-induced morphological changes of ovarian follicles and follicular macrophages. METHODS: 8 Gy X-ray irradiated on the 3-week old rats (Sprague-Dawley strain), sacrificed at 6, 12, and 24 hours after irradiation, and performed morphological studies with light and transmission electron microscopy, TUNEL, and macrophage immunohistochemistry. RESULTS: Follicular atresia increased significantly (p<0.01) at 6 hours after X-irradiation, and it was decreased significantly (p<0.01) at 12 and 24 hours after irradiation. X-ray induced chromatin condensation in the nucleus and nuclear fragmentation of granulosa cells, which were the typical features of apoptosis. Apoptotic granulosa cells were phagocytosed by the neighboring normal granulosa cells and the macrophages. During atresia of follicles, radioresistant granulosa cells were found in some follicles, which showed similar features morphologically with the granulosa cells of normal follicles. Macrophages were found both within the antrum and at the follicular granulosa layer. CONCLUSION: X-radiation induced follicular atresia by means of granulosa cell apoptosis, and radioresistant granulosa cells which have similar features morphologically with the granulosa cells of normal follicles were observed in some follicles. And the macrophages which phagocytose the apoptotic granulosa cells were located within the follicular antrum and at the follicular granulosa layer.

A case of an anterior communicating(Acom) artery aneurysm in a 36-year-old woman with polycystic kidney, and a case of multiple aneurysms(Acom. And anterior choroidal artery aneurysm) in a 49-year-old man with Marfan's syndrome are reported. Polycystic kidney was confirmed by abdominal ultrasonography and computed tomography. Marfan's syndrome was diagnosed with skeletal abnormalities(dolichocephaly, highly arched palate, cleft palate, arachnodactyly and tall slender height with excessive length of limbs) and marked elongation and tortuosity of the vertebral artery on cerebral angiography. Those patients were treated with the clipping of aneurysms. We will discuss the pathogenesis of cerebral aneurysm in those diseases with stress on the important points of management.
