We observed a significant sign in postenhancement CT of liver cirrhosis, that is visualization of portalvenous branches. During postenhancement CT scanning of liver, the portal vein can not be identifed in liverparenchyme in 84% of patients without known cirrhosis (including chronic active hepatitis). Two have the samehemodynamic changes in that there is diffuse fibrosis and resultant decrease in vascular bed. Visualization ofintrahepatic portal branches in postenhancement CT is because of decreased diffusion ability and portalhypertension.

A 33 years old house wife with accessory breast tissue is described and the literature is reviewed. The patient developed soft tumors in both axillae with axillary hair loss during the 8 th month of her 8 th pregnancy. This disorder is rather common in the literature but has been paied little attention dermatology.

PURPOSE: Autonomic dysreflexia represents one of the most serious medical emergencies in the care and rehabilitation of patients with spinal cord injury. We evaluated the effect of terazosin for the prevention of symptoms due to autonomic dysreflexia in patients with spinal cord injury. MATERIALS AND METHODS: The effect of terazosin was evaluated in 20 spinal cord injury patients with autonomic dysreflexia. All patients received terazosin as the only medication for the autonomic dysreflexia. Baseline measurements of blood pressure, the autonomic dysreflexia severity score and autonomic dysreflexia frequency score were recorded before terazoxin medication. Follow-up measurements were taken at 1 week, 1 month and 3 month after medication. All the data were statistically evaluated and the following results were obtained. RESULTS: The majority of patients(95%) had manifested headache and sweating. The autonomic dysreflexia severity score after terazosin medication decreased from an average of 9.0+/-0.6 at baseline to 6.8+/-0.7, 5.2+/-0.7 and 4.9+/-0.6 at 1 week, 1 month and 3 months repectively(p=0.001). And the autonomic dysreflexia frequency score after terazosin medication decreased from an average of 2.4+/-0.5 to 1.2+/-0.4 at 3 months. CONCLUSION: Tetazosin appears to be effective in preventing symptoms due to autonomic dysreflexia.

To evaluate whether mast cells are involved in developing pathologic feature of psoriasis, 60 biopsy specimens of patients with psoriasis were analyzed. They had not been treated for at least 1 week before skin biopsy. Histological findings in early and fully developed lesions and numbers of mast cells in their dermal papillae were investigated. The results were as follows: 1. In epidermal changes of psoriatic lesions, parakeratosis and acanthosis revealed different findings between early lesions and fully developed lesions. While early lesions revealed mounds of parakeratosis and mild to moderate acanthosis, fully developed lesions revealed confluent parakeratosis and moderate to severe acanthosis. In dermal changes of psoriatic lesions, papillomatosis revealed different findings between early developed lesions and fully developed lesions. While early lesions revealed normal to moderate papillomatosis, fully developed lesions revealed moderate to severe papillomatosis. 2. Degree of acanthosis is related to the degree of papillomatosis. The more increase in the degree of acanthosis, papillomatosis, and parakeratosis, mast cell numbers in dermal papillae were more increased. 3. Mast cell numbers in dermal papillae were more increased in fully developed lesions than early lesions. 4. These findings suggest that mast cell may play an active role in developing pathologic finding of psoriasis.

PURPOSE: To evaluate the clinical significance of the screening mammography in the detection of the breast diseases, especially breast carcinoma. MATERIALS AND METHODS: We analyzed 1,800 cases of mammography retrospectively. The mammography was done as a part of routine check in Health Counselling Center, Korea University Medical Center, during 9 months from November 1993 to July 1994. The age range was from 23 years to 76 years, mean 49.8 years, and the largest age group was 6th decade(31.4%). According to the mammographic findings, we divided the subjects into three groups; normal group, abnormal group in need of follow up study, abnormal group requiring biopsy. RESULT: On mammography, the normal group consisted of 1,534 cases(85%), and the abnormal group consisted of 266 cases(15%). The abnormal findings were benign-looking calcification(n=140), fibroadeno ma (n=29), fibrocystic changes (n=27), cyst(n=23), malignant lesion(n=15), lipoma(n=7), and others. In four of 15 cases, which were suspected to be malignant on mammograms, breast carcinoma was confirmed pathologically. In four cases of breast carcinoma, one was under 40 and the other 3 were over 50 years of age. All of the breast cancers were under 3cm in size, and the mammographic findings of breast cancer included spiculated margin(n=3), parenchymal disortion(n=3), malignant calcification(n=2) and enlarged axillary node (n=l). CONCLUSION: Screening mammogram is helpful for early detection of non-palpable breast cancer, especially for women over 50 years of age.

Evaluations of residual renal function and the therapeutic effectiveness in renal tuberculosis have largely been dependent on intravenous pyelogram or Contrast-CT scan, even though, exact renal function are not evaluated with there methads. 99mTc-DMSA is a radiopharmaceutical that is trapped in the functioning tubular cells of the kidney and therefore, quantitative renal function could be evaluoted by ineasuring the counts of renal radioactivity and concomittant evaluation of renal morphology could be passible with the analog imapes of the radioactivity. The authors retrospectively analyzed 99mTc-DMSA scans of 75 kidndys of 67 patients with confirmed renal tuberculosis. We classified the morphologies of tuberculous kidneys as 6 types. We classified the morphologies of tuberculous kidneys as 6 types such as the type with small cortical defect, with parenchymal ulcerocavernous lesions, ulcerocavernous fistula to pelvis, mass-like defects, contracted kidney with ureter visualization, and the type with nonvisualization of kidney, corresponding to the characters of renal tuberculous pathogenesis with abscess formation, ulcerocavernous fistula, and fibrosis, and correspondings to the renal anatomy with parenchyma, and pelvocalyceal collecting system. Their mean residual renal functions measured with 99mTc-DMSA uptake rates were 19.0%, 18.4%, 7.9%, 12%, 4.1%, 3.4% respectively.
