BACKGROUND: The proliferation of vascular smooth muscle cell(VSMC) is a part of the major pathogenic mechanism for atheroscle- rosis. It has been reported that L-type calcium channel plays a role in the VSMC proliferation in diabetic rats. But there is a little study results about the association between L-type calcium channel and VSMC proliferation by glucose concentrations in culture media. So we examined the association between voltage-dependent L-type calcium channel of VSMCs and the proliferative activity of vascular smooth muscle cells. METHODS: Rat aortic VSMCs were isolated from the aorta of OLETF rat by enzyme method. VSMCs were cultured in various concentrations of glucose(5.5, 25 mM). The VSMCs(1x104 cells in 24-well plates) were incubated in the presence of Bay K 8644 (10-6M) with/without verapamil(10-6M) for 48 hours. Then the proliferation was assessed by MTT(methylthiazole tetrazolium) assay and expression of L-type calcium channel mRNA was measured by RT-PCR. RESULTS: The proliferative ability and the expression of L-type calcium channel of cultured VSMCs were increased dose-dependently by the glucose concentrations(p<0.05). Bay K 8644 enhanced the proliferation of VSMC and verapamil blocked the incremental effects induced by Bay K 8644. CONCLUSION: These results suggest that L-type calcium channel may play a role in VSMC proliferation of OLETF rat.

Even though ultrasonography is a primary tool for evaluation of gynecological pelvic mass, CT can be helpful when ultrasonography is suboptimal either because of abundant intestinal gas or marked obesity. Authors experienced 3 cases of hydatidiform mole demonstrated by CT. The findings of hydatidiform mole are enlargement of uterus, low density in the uterine cavity, irregular soft tissue mass with small multiple cysts, and strong contrast enhancement of the soft tissue mass within the uterine cavity. CT can be a useful diagnostic tool for differentiation of hydatidiform mole from choriocarcioma because of good visualization of uterine wall and pelvic structures.

The idiopathic hypereosinophilic syndrome (HES) represents a heterogenous group of disorder characterized by prolonged eosinophilia of undetectable cause and multiorgan system dysfunction. Bone marrow is the most frequentry involved organ, but the most severe clinicopathologic involvement is heart. The major cause of death in patients with the HES is cardiac dysfunction especially congestive heart failure resulted from endocardial fibrosis and restrictive cardiomyopathy. We have experienced a case of DES with both cardiac and pulmonary involvements. The patient was an 18-month-old infant with poorly controlled lung abscess who complained of fever and productive cough. On the microscopic examination of pleural effusion, eosinophilic infiltration was noted. M-mode echocardiogram showed diffuse thickening of interventricular septum and left ventricular posterior wall. On the peripheral blood smear, prolonged eosinophilia was observed. We confirmed this case with bone marrow aspiration which showed eosinophilic hyperplasia.

7.MR Imaging Findings of Recurred Dermatofibrosarcoma Protuberans of the Scalp: A Case Report.

A 48-year-old man presented with a dermatofibrosarcoma protuberans (DFSP) of the scalp associated with local recurrence. Axial T1- and T2-weighted images demonstrated a well-circumscribed hypointense and intermediate hyperintense mass in the skin and subcutaneous layer of the scalp, respectively. Contrast-enhanced T1-weighted images showed the strongly enhanced mass invasion to the skin, subcutaneous layer and adjacent galeal layer. Scalp DFSP is very uncommon but is an aggressive tumor, so MR imaging diagnosis of the extent of the lesion to underlying structures, and initial wide local resection is important to prevent recurrence.

An echogenic lobulated round mass in the head of pancreas was found during abdominal ultrasonography for routine checkup on a 34 year-old man. CT and MRI showed characteristic findings of lipoma. Clinical followup confirmed intrapnacreatic lipoma, which had been reported only once proviously. This lesion should be added to the list of benign connective tissue tumor of the pancreas.

A clinical review was made on 48 cases with cor pulmonale who were admitted to medical department, National Medical Center, between 1973 and 1982, and the results were as follows : 1) Teh age of subjects ranged from 26 to 88, and their mean was 51. male to female ratio was 1.6:1 and majority of them were in their 6th and 7th decade. 2) COPD was the most common cause of cor pulmonale but pulmonary tuberculosis had also a considerable portion. Less commonly it was caused by chest deformity which was mainly from spine tuberculosis and kyphoscoliosis. 3) Almost all patients were admitted with over heart failure. 4) Laboratory features showed indirect evidence of heart failure and pulmonary hypertension in chest X-ray films, RVH patterns in EKG and hypoxia and hypertcapnea with metabolic compensation in arterial gas analysis. 5) The case fatality rate was one-forth and that from kyphoscoliosis was especially high(80%).
