PURPOSE: The aneurysmal aortitides could be classified into 4 categories by clinical features, and each category has a different principle of treatment and prognosis. The purposes of this study were 1) to classify the CT findings of the aneurysmal aortitides by the 4 categories-aortic aneurysm, aortic dissection, penetrating atheromatous aortic ulcer, and annuloaortic ectasis, and 2) to evaluate the complications of each category. MATERIALS AND METHODS: We reviewed the CT findings of 33 cases of aneurysmal aortitides, and classified them into the above-mentioned 4 categories. Thirty-two patients were examined with CT with or without ultrasound, angiography, echocardiography, or MRI. Among them, 15 cases were confirmed with operation and the rest were diagnosed with radiologic and clinical findings. RESULTS: There were 17 aortic aneurysms, 9 aortic dissections, 4 penetrating atheromatous aortic ulcers, and 3 annuloaortic ectases. Aortic rupture, the most serious complication of aortitides, occurred in 9 cases. The causes of the rupture were aortic dissection, aneurysm, and penetrating aortic ulcer in descending order of frequency. The most frequent site of rupture was retroperitoneum. CONCLUSION: Using CT with or without other diagnostic tools, we could classify the aneurysmal aotitides into 4 categories and evaluate the complications.

OBJECTIVE: To confirm the effect of calcitonin injection relieving pain in ovariectomized rats. METHOD: Thirty five Sprague-Dawley rats were randomly divided into five groups (high dose calcitonin group (112 U/ Kg), low dose calcitonin group (56 U/Kg), free calcitonin group, ovariectomy group, control group). To assess the pain in ovariectomized rats, the tail of rats were dived in waters of 50+/-1degrees C. Then the tail withdrawal time was measured (tail withdrawal test). The tail withdrawal test was performed in once a week for eight weeks. RESULTS: 1. At seven and eight weeks after injection, the tail withdrawal time of high and low dose calcitonin group compared with that of ovariectomy group were significantly prolonged (p<0.05). 2. At eight weeks after injection, the tail withdrawal time of free calcitonin group compared with that of ovariectomy group was significantly prolonged (p<0.05). CONCLUSION: The effect of calcitonin injection relieving pain in ovariectomized rats was found.

OBJECTIVE: This study was evaluated the bone protective effects of the salmon calcitonin microspheres against the cancellous bone loss in the ovariectomized rats. METHOD: The experimented rats were total 50 Sprague-Dawley female rats. They were divided randomly 5 groups. The treatment was initiated on the first day after surgery and continued for a period of 4 weeks. Bone measurements were performed in the distal femoral metaphysis and 5th lumbar vertebrae with dual energy x-ray absorptiometry at the time of 2nd week and 4th week after drug injection in all groups. RESULTS: The cancellous bone density in the ovariectomized rats treated with high dose of the salmon calcitonin microspheres was significantly higher than that of the free salmon calcitonin-treated ovariectomized rats, but less than that of the sham-operated control rats. CONCLUSION: This study shows that the salmon calcitonin microspheres were evaluated for protection against the can cellous bone loss in the ovariectomized rats. The bone protective effect of the salmon calcitonin microspheres was greater than that of the free salmon calcitonin.
