BACKGROUND: The aging process may be induced, at least in part, by reactive oxygen species(ROS). It has been though that the lung could be a good source of ROS because it has a high oxygen tension. In the present study, we invetigated the inducibility of the first and last lines against oxidative stress, superoxide dismutases (Cu/Zn-SOD and Mn-SOD) as a scavenger of O2- and metallothionein(MT) as a scavenger of OH·, respectively, in mouse lungs with age. METHODS: Oxidative stress was induced by paraquat, an intracellular superoxide generator, at 1, 4, 8, and 12 months of age and then SODs and MT mRNAs were determined by RT-PCR method. RESULTS: The steady-state level of Mn-SOD mRNA increased from 1 to 8 months but decreased thereafter. However, Mn-SOD mRNA was not induced by paraquat after 1 month. On the other hand, there was no change in the steady-state level of Cu/Zn/-SOD mRNA, which decrease abruptly at 12 months of age. Additionally, Cu/Zn/-SOD mRNA was not induced by paraquat at any age. There was no change in the steady-state level of MT mRNA with age whereas its inducibility by paraquat was intact at all ages. CONCLUSION: These results indicate that lack of induction of SODs with age may be one of the causative factors in the aging process while induction of MT may play an important role in the defense against oxidative stress. It is therefore implicated that the tissue antioxidant/proxidant balance could be one determinants of meal life span.

Meigs' syndrome is defined as a hydrothorax with ascites and a pelvic tumor, both of which resolve on removal of the tumor. Pseudo-Meigs' syndrome is a variant not possessing the original tumor cell types described by Meigs. Both these syndromes should be considered in otherwise healthy women who present with either new or recurrent hydrothorax and ascites. Pseudo-Meigs' syndrome occurs with the clinical triad of (1)ascites, (2)pleural effusion and (3)Brenner tumors, struma ovarii, benign thecomas, extreme ovarian edema, uterine leiomyomas or other benign pelvic tumors. A case of Pseudo-Meigs' syndrome associated with Brenner tumor is presented with a brief review of literatures.

BACKGROUND: Diuretic agents are widely used in the treatment of variable diseases. Although some diuretics may cause photosensitive reactions, this has been a relatively neglwted area of investigation. OBJECTIVE: The study was undertaken to examine whether or not the diuretic agents could cause phototoxicity with the photohemolysis test and with the Candida albica as test. METHOD: Photohemolysis test: Fresh human red blood cells (RHC) were washed and diluted to 200 fold of original volume with TCM buffer. Test compound suspension, were added to the diluted blood at the final concentration of 10 M. Each sample was irradiated with 50 J/cm of UVA, and control samples were incubated in water bath with light shielding. After additional incubation in a dark water bath for 30 minutes the sarnples were centrifuged. After adding Drabkins reagent, measurement of absorbance of the supernatents by speetrophotometer at 420, 540, 550nm were performed. The degree of photohemolysis was determined by comparing the results wiith the control solution. Candide elbicens test wenty microliter of each solution of arious diuretics were applied to Sabourauds dextrose agar plate in which Candida albicanp had been diffusely applied previously. Four hours after the application, 80 J/cm of UVA was irradiated. The irraicated plates and nonirradiated controls were incubated in a darlI room for 48 hours, and were examined clearzones arround the drugs as the mean of positive results fcir the phototoxic potential of the drugs. RESULTS: The photohemolyeii; vaIues of azosemide, spironolaetonet, iamterene, and xipamide at 420, 540, and 550nm were 70.57%/28.36%/31.61%/83.65%/16.40%/15.21%/75.66%/25.40%/28.17%, and 14.02%/9.11%/8.99% respectively, which exceeds the mear,injful positive value of above 5 , With the Candida olbicans test all teat solution at concentration of 1% and 5% showed negstive results. CONCLUSION: A phototoxic reaction may be triggered by azosemide, spironolactone, triamterene, and xipamide, and the possible mechanism concerned may be directed to cellular membranes. However with the negative result of knowed photosensitizers like hydrochlorthiazid and furosemide, there may be other possibilities for the explenation of phototoxicity. Thus further stirdies may be necessary to investigate more details about the cliscrepancies in greates detail.

Endometriosis is an enigmatic disease of menstruating females affecting the reproductive life. We report herein a case of perineal endometriosis in a 33-year-old woman. The patient presented two rounded, thickened plaques bilaterally on the perineum for about four year. The plaque on the right side was located mainly at the episiotomy scar. Histologic examination showed confirmative feature of glandular structures embedded in the cellular stroma and predecidual changes of late secretory phase of endometrium. Radical operation of total hysterectomy with bilateral oophorectomy and partial excision of perineal lesions were performed. There was complete resolution with no relapse by the 6-month follow-up. This is of a very rare occurrence and three cases have been reported in the Korean literatures up to date.

Objectives : 201Tl - chloride, 99mTc - MIBI, 99mTc(V) - DMSA SPECT has been used in distinguishing lung cancer from benign lesion. To compare the diagnostic efficacy of SPECT with these tumor - seeking agents, we performed three consecutive SPECT using 201Tl, 99mTc - MIBI, 99mTc(V) - DMSA in same subjects with a solitary pulmonary lesion. Methods : SPECT was carried out at 10min and 3hr for 201Tl after injection of 2 mCi, and 2hr for 99mTc - MIBI and 99mTc(V) - DMSA after injection of 20mCi, respectively, in 37 patients with a solitary pulmonary lesion(27 lung cancer and 10 benign diseases). In patients showing visual uptake on lesion site, we obtained the lesion - to - bakground(target lesion/contralateral normal lung) uptake ratio from transverse slice for each radionuclide and also calculated the retention index for 201Tl. Results : The diagnostic sensitivity of 201Tl, 99mTc - MIBI and 99mTc(V) - DMSA SPECT to lung cancer was 100%, 96% and 73%, and the specificity was 40%, 70% and 70%, respectively. The low specificities for these agents were mainly due to high positive uptake in patients with active pulmonary tuberculosis. There were no significant differences in uptake ratios and retention index between malignant and benign lesions, and among the histologic types of lung cancer Conclusion : 201Tl and 99mTc - MIBI showed higher sensitivity than 99mTc(V) - DMSA for detecting lung cancer, but was of limited usefulness in distinguishing lung cancer from benign lesion due to low specificity, especially in area with a high prevalence of active pulmonary tuberculosis.
