Extraosseous tuberculosis of the extremities is relatively rare even in the wide spread incidence of bone and joint tuberculosis. And few reports about extraosseous tuberculosis of the extremities have been published in the literatures. Eight cases of the extraosseous tuberculosis of the extremities were experienced at the Department of Orthopaedic Surgery, National Medical Center, from 1975 to Sep. 1979. Five out of 8 extraosseous tuberculosis were tenosynovitis and the others were bursitis in location. All cases were surgically excised and combined with antituberculous chemotherapy, and primarily cured.

OBJECTIVES: The study was conducted to estimate the carcinogenic risks from the ingestion of some carcinogenic pesticides (CPs) in vegetables sampled at a local agricultural product market in Seoul. METHODS: After applying a hazard identification step, we selected four pesticides, such as DDT, dieldrin, folpet, and heptachlor epoxide, for this risk assessment. Concentrations of each pesticide were measured from randomly sampled vegetables. In order to estimate the human exposure levels, we combined the concentration of pesticides in the vegetables with consumption rate of those vegetables. Three scenarios were hypothesized for human exposure assessment. Scenario I was the most conservative which supposed the undetected CPs would be the detection limit values. Scenario II was assumed that the undetected CPs would be a half of the detection limit values, and finally scenario III merely considered only values greater than the detection limit values. We finally presented the estimated carcinogenic risks on the basis of the traditional risk assessment procedure suggested by U.S. EPA. RESULTS: Pesticides including DDT, dieldrin, folpet and heptachlor epoxide were detected in 9 samples (6%) in the range of 0.0006~0.09ppm. The daily intake levels of carcinogenic pesticides were estimated in the range of 0.0009~0.0079 microgram/day. As we expected, excess cancer risks based on scenario I was also the highest (1.1x10-8~ 5.5x10-5). CONCLUSIONS: We found that the estimated risks from the pesticides we investigated were not serious. We, however, propose that a continuos monitoring is needed to make sure for the protection of public health.

We report a case of primary cutaneous mucinous adenocarcinotna in a 64-year-old female. The tumor was about 2cm in size, forminga round dome-shaped alopecic scalp mass which had gradually increased in size over about 5 years, Histalogic examination revealed that the tumor was divided into numerous compartments by strands of fibrous tissue. In each compartment, abundant amounts of pale-staining mucin surrounded nests or cords of moderately anaplastic epithelial cells. We couldn't find any evidence of internal neoplasms as a source of metastasis. We resected the tumor with approximately a 1 cm margin and then performed a split thickness skin graft.

Differential diagnosis between tuberculous epididymitis and nonspecific chronic epididymitis is one of the most difficult problem in the field of urology. The definitive diagnosis of tuberculous epididymitis is often made by pathological examination of the epididymectomy or orchiectomy specimen. However, the preferred approach to treatment of tuberculous epididymitis is primarily antituberculous chemotherapy and we believe that as a primary measure, surgical procedure is avoidable with careful clinical work-up. A clinical comparative investigation was undertaken on 20 cases of tuberculous epididymitis and 13 cases of nonspecific chronic epididymitis, diagnosed by histopathologic examination during recent 6 year period. Tuberculous epididymitis occurred most frequently in men aged 21-30 years (80%), whereas nonspecific chronic epididymitis occurred frequently in men aged above 31 years (69.2%). Tuberculous epididymitis and nonspecific chronic epididymitis Were present clinically as painless scrotal mass in 70%, 53.8%, painful scrotal mass in 30%, 46.2%, and voiding symptoms in 15%, 7.7% respectively. Scrotal swelling were present in 30% of tuberculous epididymitis, but only in 7.7% of nonspecific epididymitis. Irregularity of mass were noted in 65% of tuberculous epididymitis, and in 23.1% of nonspecific epididymitis. Scrotal fistula were present only in 5% of tuberculous epididymitis. Of the patients with tuberculous epididymitis, 20% had a history of tuberculosis, and 46.1% of the patients with nonspecific chronic epididymitis had a history of acute epididymitis. In tuberculous epididymitis, clinical findings of concurrent infection with tuberculosis were found in kidney, prostate, vas, lung, and testis in order of frequency. Past history of tuberculosis or acute epididymitis and clinical findings of concurrent tuberculous lesions were helpful for clinical diagnosis, in 70% of the patients with tuberculous epididymitis and 46.2 % of the patients with nonspecific chronic epididymitis.

Although a lot of articles examining concomitant intrauterine and ectopic pregnancy have been presented, we have not found any reports on ectopic implantation of chorionic villi in the vagina with normal intrauterine pregnancy. We experienced a case of chorionic villi on the vaginal wall as a hemorrhagic mass during the second trimester of pregnancy. A pregnant woman (gestational age of 16 weeks and 1 day) visited our hospital due to vaginal bleeding. There was no abnormal finding except vaginal hemorrhagic mass, and the mass revealed a product of conception.

Retroviral vector provide a highly efficient method for gene transfer into eukaryotic cells. This vector system can be divided into two components; the retroviral vector itself and the retroviral packaging cell line. The key improvement in the design of these two components are. focused on two aspects; the reduction of helper virus production and high titer-virus. We used PA317 for retrovirus packaging cell line, for its high producibility of viral titer, To test the ability of the vectors to generate high titer-virus, we have chosen four different retroviral vectors; LN, LNSX, LNCX and LXSN. To test easily the viral titer, we have made recombinant construction with CD4 and CD8, checked their viral titer and stained their surface expression. LXSN which contain SV40 early promoter in front of leo gene showed best results in viral transient transfection assay, dot blot assay and surface expression. In addition, recombinant containing CD8 generally showed much higher viral titration and surface expression than CD4.
