A myocardial beidge is an anatomic arrangement in which an epicardial coronary artery becomes engulfed for a limited segment by mycardial fibers. Myocardial bridges are not uncommon finding at coronary angiography and are identified by the systolic narrowing of the affected artery, mainly the left anterior descending coronary artery. The significance of myocardial beidges is controversial. These are frequently found at autopsy, and have been associated with episodic angina, tachcardia-induced ischemia amd sudden death during strenuous exercise. It has been suggested that clinical mamifestations of myocardial ischemia could be the result of severe reductions in the myocardial blood flow during the systole caused by the mylcardial bridge. We report two cases of myocardial damage occuring in a previous asymptimatic patients, hacing myocardial beidge in a left anterior descending coronary artery. This report strengthens the view that myocaridal bridges may, on occasion, cause ischemis

Although uterine arterovenous malformation(AVM) is a rare cause of menorrhagia or postmenopausal bleeding, it is important to consider that curettage may precipitate life-threatening hemorrhage and therefore it is contraindicated when AVM is suspected. Special investigations such as hysteroscopy, Doppler flow ultrasound and angiography are important diagnostic tools, and transarterial embolization(TAE) has replaced hysterectomy as the treatment of choice in women who wish to retain their fertility. But due to the high incidence of collateral vessels, recurrence of the vascular malformation after TAE is common. We have experienced two cases of AVM, one of which was managed by TAE in combination with surgical arterial ligation.

Adenomyosis is a common disease of middle-aged women and adenomyoma is a variety of adenomyosis that formed localized tumor. Cystic degeneration of an adenomyoma is a rare clinical manifestation. A 30-year-old parous woman suffered from severe dysmenorrhea and menorrhagia for about 5 months, was operated under the impression of endometriosis of the pelvis. Following the operation, cystic degeneration of an adenomyoma was found incidentally. The authors experienced a case of adenomyosis that formed cystic tumor of uterus and presented with a pertinent literatures.

The primary objective of this study is to estimate of the mesiodistal crown diameters of the unerupted permanent successors derived from the mesiodistal crown diameters of the deciduous teeth in Korean population. The subjects were 54 indiciduals (twenty nine boys and twenty five girls) with normal occlusion aged 6 to 13 years. The mesiodistal crown diameters of the deciduous and the successional permanent teeth were measured from the longitudinal dental cast models using the shding calipers (Mitutoyo Co.) From the study, the results are as follows, 1. Sex differences of mesiodistal crown diameters were less in the deciduous teeth, but male were more than that of female in the successional permanent teeth. 2. The mesiodistal crown diameters of the deciduous central incisors, lateral incisors, canines were smaller than that of the successional permanent teeth and the deciduous 1st molars, and 2nd molars were more larger than that of the successional permanent teeth. 3. Size differences between sum of the mesiodistal crown diameters of central meisors and lateral meisors in the decidous teeth and the successional permanrnt teeth were 7.20 +/- 1.79 mm in upper, 5.38 +/- 1.64 mm in lower and that of canine, 1st molar and 2nd molar in the deciduous teeth and the successional permanent teeth were 0.56 +/- 1.19 mm in upper, 2.22 +/- 1.19 mm in lower. 4. In male, the correlation coefficients between the upper deciduous central incisor and the successional permanent tooth (r=0.57) and in female, the correlation coefficients between the upper deciduous 1st molar and the successional permanent tooth (r=0.67) appeared the highest. 5. The regression constants were determined to estimate the mesiodistal crown diameters of the unerupted successional permanent teeth.
