OBJECTIVE: Although ovarian cancer is the leading cause of death among all cancers of the female reproductive tract, the genetic alterations involved in ovarian cancer remains largely unknown. Recently, mutations of the p53 gene have been documented in many types of human cancer including ovarian cancer. METHODS: In tbe present study, p53 gene mutation was examined in DNA samples extracted from paraffin embedded surgical specimens of ovarian cancer. Furthermore, clinicopathological parameters were examined in relation to p53 gene mutation in order to understand the role of p53 mutation in the development of ovarian cancer. Using the polymerase chain reaction(PCR) and single strand conformational polymarphism(PCR-SSCP), p53 gene mutation was examined and the mutations were confirmed by DNA scquencing in 17 cases of ovarian cancer. RESULTS: Abnormal bands indicating mutation were detected in 2/17(11.8%). DNA sequencing confirmed in 2 mutations and revealed C to T and A to T nucleotide chmges. In clinicopathological parameters, FIGO stage, grade, and recunence were not correlated with the p53 gene mutation. However, the recurrence rate was higher in patients with mutant p53 compared with those with wild type p53(50.0% vs 13.3%), altbough this is not statisticaUy significant. CONCLUSION: In conclusion, p53 gene mutation shows no correlation with stage, grade and recurrence, and p53 gene mutation does not appear to be a marker that predicts the biological behavior or the outmme of the disease. This study suggested useful data to elucidate the mechanism of chemotherapy-resistant ovarian cancer and further p53 expression assay would be mandatory for p53 nonfunctioning ovarian cancas.

Testicular involvement in male patients with leprosy is well documented and may be associated with impotence, sterility and gynecomastia. Testicular histology shows atrophy of the seminiferous tubules with hypertropy and clumping of Leydig cells and hyalinization of the small and medium sized vessels. The hormonal functions of the testes have been studied by a number of workers, usually in patients with testicular atrophy and gynecomastia. In these particular patients, androgens are generally diminished while gonadotropins are increased. The pathogenesis of testicular damage is uncertain, though Wall and Wright(1974) found that testicular germinal cell antibodies were present in 75% of lepromatous, and postulated that :autoirnmunity, Erythema Nodosum Leprosum imrnune complex damage and direct invasion by Mycobacterium leprae may all be contributory.

Multiple cerebral infarction developed in a 36-year-old woman with adenocarcinoma of the right lung with direct cardiac invasion. Neurological examination and brain MRI showed findings of ordinary infarction. Transesophageal echocardiography showed left atrial pedunculated mass which was the potential source of embolism. We report a rare case who had such multiple spontaneous tumor emboli large enough to result in clinically detectable cerebral infarction.

The need for film recording in endoscopic practice is important with the present demand for documentation and teaching (legal problem). The electronic endoscopy which has a very small charge coupled device (CCD) at the distal end of an endoscope yields several times more resolving power than conventional optical endoscopes. However the system has not been utilized in Urologic field because there has not enough space for CCD at the end of the telescope comparing to the endoscope in Gastroenterology field. However the video converter with CCD could be adapted to the eyepiece of the telescope, and the automatic monitor photo unit (CVP 600, SAMSUNG, KOREA), video system and monitor were used for imaging, which is so called Urologic Video Information System (UV1S). The image processing was done by instantaneous system (CCD color camera, EC-202 II, ELMO, Japan) with conventional optical light source. From September 1992 to August 1996, we did cystoscopic examination with CCD in 1079 cases.
