Ninety-three dry mandibles in Korean adults were radiographed and fifty-two hemimandibles were sectioned in an attempt to analyze the intramandibular courses of the mandibular canal and the internal structure of the mandibles. On radiographs, the intramandibular course of the mandibular canals was most in which located in the middle portion of the mandible, the shape of the mandibular canals was almost round and the average diameter of the mandibular canals was 2.0 +/- 0.4mm, encapsulated by thin cortical plates of 0.5mm thickness on sectioned specimens. In regard of facio-lingual relation, the prevalence of pattern which the mandibular canal ran nearly to the lingual cortical plate, and turned abruptly towards the buccal side was 70% of observed specimens. According to superior-inferior relation, the prevalence in which mandibular canals ran inferiorly, anteriorly and then, had an angle superiorly in the second mandibular molar region was 39.0%. Taken all together, in most of the case, the anterior border of the mandibular canal is located around the premolar region, and the mental foramen is opened nearly the second premolar. Therefore, it may be suggested that osteotomy has to be taken at the anterior place next to the canine region, at the 2.4mm below to the mental foramen on genioplasty.

We report a rare cause of lung cavities, occurring in a patient with intrapulmonary cystic teratoma. Computed tomography (CT) provided us more detailed informations about the tumor characteristics containing fat and calcification, which could not be distinguished on the plain radiographs. In addition, CTscans clearly demonstrated the dilated anterior segmental bronchus of the left upper lobe entering the posterior aspect of the cavity.

The limb-body wall malformation complex is a sporadic congenital anomaly characterized by protean manifestations. The diagnosis is based upon the presence of at least two out of craniofacial anomaly, body wall defect, and limb abnormalities. We present a case of limb-body wall malformation complex. This case shows abdominal and pelvic wall defects with eventration of the viscera. It also shows an absence of right kidney, polycystic left kidney, absence of external genitalia and anus, and lower extremity abnormalities. The right lower extremity is absent and the deformed left leg shows malformed foot-like structure attached to the shin in addition to a normally positioned left foot. Our patient is the first case of complete absence of the external genitalia associated with limb-body wall malformation complex in Korean publications and the seventh in English publications.

PURPOSE: To evaluate the findings and the role of CT in plexiform neuro-fibromatosis of the mediastinum. MATERIALS AND METHODS: We retropectively reviewed the CT scans of five patients with plexiform neurofibromatosis of the mediastinum. The CT scans were reviewed with attention to the distribution of the lesions, appearance and attenuation of mediastinal lesions, enhancement pattern after intravenous contrast infusion and associated findingssuch as intercostal neurofibroma. RESULTS: In all five patients CT scans demonstrated fusiform low attenuated masses which were oriented longitudinally and extended over multiple contiguous scans along the distribution of major mediastinal nerves. In four patients, mediastinal lesions appeared infiltrative, obliterating adjacent mediastinal fat plane. One patient had well defined fusiform masses along the major mediastinal nerves. Postcontrast enhanced CT scans revealed slight central enhancement in two patient and no contrast enhancement in three patients. Associated findings such as neurofibromas of intercostal nerves and sympathetic trunk, or subcutaneous neurofibromas were detected on CTscans in all five patients. CONCLUSION: Characteristic CT findings of low attenuation masses along the major mediastinal nerves are helpful to differentiate plexiform neurofibromatosis from mediastinal lymphadenopathy and to prevent from misreading as a malignant disease.

A number of noninvasive technics have been advocated as reflecting left ventricular performance. These methods include systolic time intervals, echocardiography and imaging of the left ventricular chamber with radionuclides during systole and diastole. Radionuclide evaluation of left ventricular function by means of the gamma camera and gating currently appears to be the most reliable noninvasive method for approximating angiographic evaluation of left ventricular performance. Utilizing the radionuclide angiography, we measured the left ventricular function in 19 normal healthy control, 60 patients with coronary artery diseases 7 patients with dilated cardiomyopathy, 5 patients with hypertension. 1) Left ventricular ejection fraction decreased in 12 patients with anterior myocardial infarction (39.9+/-11.6%), 17 patients with inferior myocardial infarction (49.9+/-8.4%) and 7 patients with dilated cardiomyopathy (19.0+/-5.8%), and there was a statistically significant difference compared with 19 normal control group (63.5+/-8.2%)(p<0.005). However there were no statistically significant difference between normal control group, patients with hypertension (58.8+/-7.6%) and patients with angina pectoris (60.1+/-6.5%). 2) Left ventricular ejection fraction decreased in both anterior and inferior myocardial infarction, and there was a statisically significant difference between both groups (p<0.01). All 13 patients with acute myocardial infarction had abnormal LVEF (40.5+/-9.1%) whcih was significantly lower than that of 16 patients with old myolardial infarction (50.1+/-10.5%)(p<0.01).

Retrograde ejaculation, semen flows into the bladder because of failure of the bladder neck to close, is to uncommon cause of male infertility. Many pregnancies have been tried by artificial intrauterine insemination of the wife with the husband's sperm recovered from voided urine. Major problems that use of retrograde ejaculation specimens for artificial insemination are (1) the acidity of the urine, (2) the osmotic pressure of the urine, (3) the dilution effect caused by the urine, and (4) urine contamination of the cell suspension. We report a case of successful pregnancy using Ham's F-10 medium, which contained 10% cord in the retrograde ejaculation patient.
