Pertutaueous transluminal angioplasty is the treatment of choice for renovascular hypertension in cases due to the renal vascular occlusion which is not severe enough to pass dilatation catheter. The advantages of percutaneous transluminal angioplasty are the use of local anesthesia, its noninvasiveness without surgical risk, feasibility of repetition and shorter hospital days compared with surgical methods. We are presenting a case of renovascular hypertension due to atherosclerosis cured by percutaneous transluminal angioplasty with the review of literatures.

Although some recent studies showed that increased synthesis of vasodilatory prostaglandin E2 were possible factor in the maintenance of renal blood flow during the states of impaired renal perfusion. However this fact is not studied in cases of upper urinary tract calculi yet. This study is to estimate the value of urinary prostaglandin E2 in cases of upper urinary calculi. The amount of prostaglandin E2 in urinary excretion was measured by radioimmunoassay in ten cases of complete ureteral obstruction compared with normal side, in eleven cases of partial ureteral obstruction compare with normal side and in three cases of bilateral renal calculi. The results obtained were summerized as follows: 1. The values of urinary prostaglandin E2 were highly elevated in cases of bilateral renal calculi. 2. In ten cases of complete ureteral obstruction, the values of urinary prostaglandin E2 decreased in comparison with those of the normal side. 3. In eleven cases of partial obstructions of the ureter, urinary prostaglandin 2, values were elevated than those of the normal side.

Mach bands, a visual phenomenon resulting from lateral inhibitory impulsess in the retina, are recognized aslucent or dense lines at the borders of different radiographic densities. A number of clinical situations have been described in which Mach bands may cause difficulty in radiographic diagnosis. Photodensitometric measurement of the film can differentiate the true change in film density from the Mach band which is an optical illusion. Authors present several examples of photodensitometric tracings of Mach bands, with the brief review of themechanism of their production.

Benign polyps with prostatic type epithelium (BPPE) in the male urethra is known as a rare case. The common signs of reported cases are painless gross hematuria, hemospermia, microscopic hematuria, dysuria, frequency and postatism in young adult. We are reporting three cases of benign polyps with prostatic type epithelium of the verumontanum and the clinicopathological findings of these cases with the references.

BACKGROUND: Traditional visual reading of patch-test reactions is a rather subjective method, lacking the sensitivity and reproducibility needed in experimental studies. Recently the laser Doppler perfusion imaging (LDPI) has been used to measure objectively the increase in superficial blood flow which results in the appearance of erythema. OBJECTIVE: We designed this study to examine the relationship between the LDPI measurement and visual reading after patch test to several different irritants. METHODS: In this study, reading of erythema in experimentally-induced irritant contact dermatitis was performed visually and by laser Doppler perfusion imaging (LDPI). In addition, we investigated whether the LDPI measurement was appropriate in the routine patch test clinic. RESULTS: A close correlation was shown between the 2 methods (r=0.9046, p<0.001) and the LDPI producing mean adjusted perfusion values (APVs) was able to discriminate between the different visual grades. CONCLUSION: LDPI is a valuable instrument to objectively assess intensity of irritant patch-test reaction, and is indeed one of the few methods which overcomes the inter-individual variations in visual reading, but this instrument is not appropriate to use routinely in patch test clinic because of unacceptably long measurement time.

Leiomyosarcoma of the penis is an extremely rare disease. We have encountered a case of leiomyosarcoma of the penis in a 45 year old man. On staging work up. local invasion to corpus cavernosum. but no evidence of lymph node metastasis was evident. After the confirmation of leiomyosarcoma by excisional biopsy, the patient underwent partial penectemy. Herein we report this case with the review of literatures.

Estrogen replacemetn therapy is known to reduce the incidence of cardio-ascular disease in postmenopausal women, and its beneficial effect is thought to be mediated in part by favorable changes in serum lipoprotien levels. However, the long-term effects on serum lipoproein levels of estrogen in low doses currently used have not been precisely evaluated in Korea. In postmenopausal women with uterus, progestogen should be added to protect the endometrium from the hyperplasia or carcinoma induced by unopposed estrogen. However, progestogens may adversely influence the beneficial effects of oral estrogen. To evaluate the impacts of progestogen on the lipid and lipoprotein levels during estrogen replacement therapy, we conducted the 1-year trial of conjugated equine estrogen(Premarine, 0.625mg/day) with or without cyclic prgoestogen(medroxy-progesterone acetate: MPA, 10mg/day for 12 days) in 120 postmenopausal women. Serum total cholesterol, triglyceride, HDL cholesterol, LDL cholesterol levels in fasting state were measured in all subjects before treatment and at 12 months during treatment. The value of post-treatment levels were compared with that of baseline levels. In patients who received either premarine only or premarine plus MPA, serum HDL cholesterol levels increased significantly. While premarine plus MPA group showed a smaller increase in HDL cholesterol than premarine only group. And premarine plus MPA group showed a significant decrease in LDL cholesterol, total cholesterol, and triglyceride. While premarine only group showed a significant decrease in LDL cholesterol, but no statistical significance in total cholesterol and triglyceride levels. These results suggest that the addition of MPA at the daily dose of 10mg for 12 days cyclically in estrogen repalcement treatmetn appears to lessen the change to lipid and lipoprotein levels induced by unopposed estrogen, therefore maintain the longterm favorable effects on serum lipoprotein levels in postmenopausal women.

STATEMENT OF PROBLEM: A tenderness of the dentin after tapering of teeth for dental prosthesis is a common phenomenon. In practice, the alternative desensitizer may be used for minor pain after tapering of teeth. PURPOSE: In this study, the desensitizers were used to investigate the affect decreasing of shear bond strength according to the use of various cement, such as resin, Glass Ionomer, and phosphate cement. MATERIAL AND METHOD: Three different desensitizers were used on this study. Compositions of two dentin desensitizers were HEMA(hydroxyethylmethacrylate) and glutaraldehyde. The other one is oxalic acid. Three dentin desensitizers applied on 12 degrees taper teeth. Then, Ni-Cr crowns were bonded with Resin cement, Zinc Phosphate (ZPC) cement and Glass Ionomer (GIC) cement. 120 human premolar teeth were used for specimens. The specimens were divided into four group as the reference and the empirical each with thirty specimens, then further divided into 12 group according to type of desensitizers and cement types. The shear bond strength were measured by Instron multi task instrument. RESULTS: According to the result, the measured shear bond strength in order from the weakest to the strongest in general was ZPC, Resin, and GIC. And it is found that the application of desensitizers on dentin surface does not affect the shear bond strength. CONCLUSION: Dentin desensitizers that alleviate or prevent a dentin tenderness, usually contains HEMA and glutaraldehyde compounds. Such desensitizers are widely used in clinical studies. By applying the dentin desensitizer on the exposed dentin surface, the dentin capillary are blocked and periodontal membrane and cementum can not be drawn in pulp cavity. Since HEMA and glutaraldehyde may cause harm to the pulp cavity, an alternative desensitizer was developed.
