PURPOSE: To evaluate further the right minor and major fissure on thin-section narrow-interval CT scans with particular emphases on orientation, degree of completeness. MATERIALS AND METHODS: Thin section CT scans from 10 mm distal to carina to the proximal basal segmental bronchus were obtained at 5 mm invervals in 50 consectutive subjects. Orientation, degree of completeness, and the relationship of the minor and major fissure on thin-section CTscans were analyzed. RESULTS: Four principal types of the minor fissure could be identified according to the highest point of the upper surface of the middle lobe. At bronchus intermedius level, the major fissure appeared with its medial end anterior to lateral end in 45 subjects. The minor fissure was complete in only 10 subjects (20%). Completely absent minor fissure was noted in four subjects (8%). The major fissure was incomplete in 17 subjects (34%) at bronchus intermedius level. the minor and major fissure intersected each other in only 27 subjects (54%). The hig best point of intersection was variable. CONCLUSION: There are much more variations in the fissural complex in our study than in previous reports and these variations can be visualized well on thin-section CTscans.

The CT findings were reviewed in two patients with injuries to the gallbladder following blunt trauma. In one patient high attenuation of intraluminal blood clot within the gallbladder and associated hemoperitoneum were identified. Another patient was represented hemoperitoneum and bile leakage into the peritoneal cavity due to laceration of the fundus of the gallbladder which appeared contrasted.

Pulmonary endomertiosis is a rare disorder with the typical symptom of hemoptysis during menstruation (catamenial hemoptysis). We report a case of a 19-year-old woman, gravida 0, with 3-month history of catamenial hemoptysis which was confirmed with chest computed tomography. She was treated by means of thoracoscopic wedge resection for the right lesion and fuperior segmental resection through the left thoracotomy, successively. Preoperative fluoroscopy-guided hooking for thoracosopic target lwsion was helpful in circumstances with one lung anesthesia. Four months of follow-up after an uneventful discharge revealed out no recurrence of catamenial hemoptysis in symptoms and images.

We report a case of Holt-Oram syndrome associated with tetralogy of Fallot. Right thumb was digitalized, and left thumb was hypoplastic and dislocated at metacarpopharygeal joint. Thrombocytopenia in peripheral blood and megakaryocytic hypoplasia in bone marrow was accompanied. Brief review was done with emphasis on embryologic pathogenesis.

After pantethine in doses of 540 mg per day was administered for 8 weeks in 20 patients with hyperlipidemia, the serum levels of total cholesterol, triglyceride and HDL-cholesterol were compared with the pretreatment level. The serum level of total cholesterol decreased to 240+/-52 mg%[mean+/-standard deviation] after 4 weeks and 223+/-41 mg% after 8 weeks from the pretreatment level of 293+/-38 mg%(p<0.01). The serum triglyceride level also decreased to 254+/-109 mg% after 4 weeks and 239+/-114 mg% after 8 weeks from the pretreatment level of 375+/-126 mg%(p<0.01). But, there was no significant change in the serum levels of HDL-cholesterol before and after treatment (56+/-27 mg% beforAfter pantethine in doses of 540 mg per day was administered for 8 weeks in 20 patients with hyperlipidemia, the serum levels of total cholesterol, triglyceride and HDL-cholesterol were compared with the pretreatment level.

OBJECTIVES: Manganese is cytotoxic to the central nervous system including basal ganglia. Its toxic mechanism is related to oxidative stress, mediated by toxic free radicals but is specultives. In the present study, we have investigated to manifest apoptosis in manganese-induced cytotoxicity in primary neuronal cell culture of rat basal ganglia. METHOD: To detect apoptotic neuronal cells were stained by the terminal deoxynu-cleotide(TdT)-mediated dUTP nick end-labelling(TUNEL) method and apoptotic changes in nuclei of neurons were observed by electron microscopy. RESULTS: We showed that TUNEL immunostain showed brownish signal in the nuclei of apoptotic cells and the proportions of apoptotic cells in Manganese treatment groups were more higher than controls. On transmission electron microscopy, there were chromatine condensation with margination toward nuclear membrane and condensation of cytoplasm in the treated with luM MnC1, for 48 hours in a basal ganglia neurons. Apoptotic bodies were found and consisted of semilunar-like condensed nuclei with relatively intact cytoplasmic organelles. CONCLUSIONS: Apoptosis appears to be one mechanism in the manganese-induced neuronal cell death. Manganese intoxication is a convenient model for apoptosis study.

To present CT and clinical features of active tuberculomas, we analyzed retrospectively CT findings of 14 tuberculomas (n=14) in 13 patients which appeared as solitary pulmonary nodules on plain radiographs and evaluated the response of tuberculomas to antituberculous chemotherapy. Nine tuberculomas (64%) were ovoid in shape and 10 (72%) showed smooth margin. Twelve(86%) tuberculomas were shown as low density lesions on unenhanced or enhanced CT scans. Calcification and cavitation were noted in three (21%) and eight (57%) tuberculomas respectively. Seven (50%) tuberculomas were accompanied by satellite nodules. Acid-fast bacilli (AFB) was positive in all tuberculomas in sputum, lavage fluid, or percutaneous transhoracic needle aspiration (PTNA). Smear and culture of lavage fluid and PTNA aspirate were superior to the detection of AFB than sputum examination. Follow-up study with antituberculous chemotherapy in 14 tuberculomas resulted in complete disappearance in three, decrease in size in seven, and no visible change in the remaining four. These observations suggest that tuberculomas are well-defined, ovoid, and low-density nodules containing calcifications and/or cavitations. Tuberculomas are relatively indolent even with threatment.
