PURPOSE: To find the magnetic resonance (MR) imaging patterns and to determine the viability in normal, infracted and reversible ischemic testis of the rat. MATERIALS AND METHODS: Fifteen Sprague-Dawley rats were examined and they were divided into four groups. Group 1 was the control group, group 2 had a complete testicular artery ligation, group 3 had a complete ligation with reperfusion after 1 hour and group 4 had a complete ligation with reperfusion after 12 hours. All four groups were imaged every 5 minutes for 30 minutes. Delayed MR imaging was obtained every 30 minutes for 90 minutes. Two follow-up MR images were performed in all groups at a one-week interval. The signal intensity was measured in the normal testis, ischemic testis, and in muscle, water and fat in every rat at each time, with the phantom attached near the scrotum during the scanning. The signal intensities were analyzed statistically. RESULTS: On initial and 2-week follow-up examinations, the pattern of change differed among four groups (p<0.001). Group 1 and Group 3 did not show any marked change over time at each examination. Group 3 showed strong enhancement at the first week follow-up. Group 2 showed steadily delayed enhancement at each examination. Group 4 had same pattern with the Group 2 with higher enhancement intensity in parallel. CONCLUSION: MR images with Gd-DTPA could be useful for the diagnosis of damaged testicular tissue and for the determination of testicular viability.

BACKGROUND: According to the areas and people that are examined, there are many differences in the prevalence of syphilis in Korea. However, the reactive rate of the serologi test for syphilis showed an increase in the 1960s, and it has deerea@sed from the beginning of the 1970s. OBJECTIVE: Comparing the results of tke serologic test for syphilis which lotad been performed for the 5 years(1987-1991) on the physical examines and pregnant women who were considered as healthy, with the results with normal people, who were considered as healthy, which had been already reported, we tried to observe the change of reactive rate of serologic test for syphili. METHODS: The serologic test for syphilis, including serum VDRL test and serum TPHA test, were carried out on 25,254 healthy adults(20,405 were physical examineea eamined at National Medical Center and 4,849 were pregnant women delivered at National Medical Cer ter). RESULTS: The reaetive rate of serum VDRL test was 0.8% in 25,25 the althy adults(physical examinees 0.8%, pregnant women 0.7%). There were no stistically differerces between the annual incidences. 85.5% of VDRL-reactive subjects showed low VDRL titers(below 1:4) by the quantitative serum VDRL test, The biologic false positive reaction of serum VDRL test was 29(19.5%) in 149 VDRL-reactive subjects, using serum TPHA test as a standard. CONCLUSION: This study suggested thai, there was a decrease in the prevslence of syphilis in Korea.

The skin manifestations of secondary syphilis, termed syphilid, show macular, papular and papulosquamous rashes in most cases, but may show lots of other clinical findings. We report a case of syphitid simulating purpura annulsris telangieitodes in 25-year-old male who had a history of genital ulcer 2 months ago. The skin lesion showed diffuse erythematous, 1-3 cm sized, telangiectatic annular patchea and purpuric plaques on both lower extremities and discrete papulosquamous rashes on both soles. The results of the serologic test for syphili was found to be reactive to 32 dilution in serum VDRL test and positive in serum TPHA test. Histovathologically, we could observe the obscuring of dermoepidermal juction, coat-sleeve-like perivascular infiltrate composed of mononuclear cells and a few plasma cells, and endothelial swellings. Afte the treatment with benzathine penicillin G, the titer of serurn VDRL test was decreased abruptly to 4 dilution and the skin lesions disappeared completely.

A 24-year-old woman was seen for evaluation of an skin lesion on thiright nipple. Examination revealed a solitary 1.5 x 1cm-sized, erythematous, oozing, eroded andruted, verrucous nodule on the right nipple. A small amount of serous discharge was found but there was no pain or tenderness. Histopathologic findings showed cystic invaginations extending down vard from the epidermis and papillary projections extending into the lumina of the invagination. Pupiae were lined by two rows of cells. In stroma, there were marked inflammatory infiltrates containing any plasma cells. The overlying dermis showed an adenomatous growth pattern with a prolifertion of round, oval or irregular shaped ducts and fibrotic stroma.

Conjoined twins occur when there is imcomplete fission of the inner cell mass later at approximately 13 to 15 days after fertilization. The earlist case in the literat.ure appears to be that of the Biddenden Maids who were born in England in 1100. since then over two hundred cases of successful separation were reported on literature. And also successful separation cases were reported by Seung et al.(1991) in Korea. Conjoined twins occur between one in 50,000 to 100,000 births but real incidence is one in 200,000 because two thirds are stillbirth or died immediately after birth. The conjoined twins are not associated with maternal age, race or family history and 70 % of them are females. We experienced a case of conjoined twins with omphalopagus and performed surgical separation. A brief review of related literatures was done.
