51. Cathepsin D and plasminogen activator inhibitor type 1 in normal, benign and alignant ovarian tissues : a preliminary reportMarina Šprem, Damir Babić, Marija Abramić, Duško Miličić, Ivan Vrhovec, Janez Škrk, Maja Osmak, 2000, original scientific article Abstract: Background. The aim of the present study was to determine the concentration ofcathepsin D (Cath D) and plasminogen activator inhibitor type 1 (PAI-1) in normal ovarian tissues, benign and malignant ovarian tumor tissues, and to asses relationship between Cath D and PAI-1 content, and some clinical and pathohistological parameters. Materials and methods. Cath D contents and PAI-1concentrations were determined (using immunoradiometric ELSA-Cath D assayand commercial IMUDIND R ELISA immunoassay, respectively) in 35 samples: 10 normal ovarii, 10 benign, 10 primary malignant and 5 metastatic ovarian tumors. Results. The concentrations of Cath D were significantly higher in malignant (32.89+-14.26 pmol/mg protein ) and metastatic (31.42+-10.24 pmol/mgprotein), than in normal (13.68+-4.03 pmol/mg protein) and benign (17.89+-13.13 pmol/mg protein) ovarian tissues. There was no statistical differences in the concentrations of PAI-1 between normal, benign, malignant and metastatic tumor specimens. The concentrations of Cath D as well as PAI-1 did not correlate to the age of patients, menopausal status, parity, GOG risk group, clinical stage or pathohistological grading. Conclusion. Concentrationsof Cath D (but not PAI-1) were significantly increased in malignant and metastatic ovarian tumor tissues when compared to normal and benign ovarian tumor samples; they were independent from pathohistological andclinical parameters.

56. Local excision of flat adenomas of the rectum in the period from 1987 to 1991Janez Novak, 1997, original scientific article Abstract: In a period of 5 years, 35 patients underwent operations on for flat adenomas of the rectum located at a depth of 10 cm from the anocutaneous line. All the tumours were removed by transanal submucous excision. The average period of follow-up was 22 months. Three recurrences were detected and treated with reoperation. No major complications occurred. We consider our method suitable for clinical use if combined with careful follow-up.

59. Prognostic value of staging laparotomy in supradiaphragmatic clinical stage I and II Hodgkin's diseaseMarjeta Vovk, Tatjana Šumi-Križnik, Marija Jenko-Fidler, Gabrijela Petrič-Grabnar, Marinka Kremžar, Janez Novak, Mojca Senčar, Branko Zakotnik, Alenka Vodnik-Cerar, Branimir Jakšić, 1996, original scientific article Abstract: In the period 1974-1989, 219 patients with supradiaphragmatic clinical stage I and II Hodgkin's disease were treated at the Institute of Oncology in Ljubljana; of these 95 (43%) patients underwent staging laparotomy. Of laparotomized patients, those with pathological stage III-IV, and of non-laparotomized, those with unfavorable prognostic factors (B-symptoms, bulky mediastinum) received chemotherapy: the remaining patients were treated by irradiation. No statistically significant difference in the survival and disease-free survival between laparotomized and nonlaparotomized patients could be found.
