    Notizen: Abstract. Oxolinic acid (OA), oxytetracyline (OTC) and trimetoprim (TMP) were investigated in whole gutted rainbow trout, Salmo gairdneri Richardson, and in their skin, muscle and blood, at 6, 12 and 18°C. Concentrations of drugs were measured by high-pressure liquid chromatography. It is recommended that withdrawal times for rainbow trout be based on whole gutted rainbow trout and not, as in earlier investigations, from residual concentrations in muscle. Any concentrations in rainbow trout feed were found to be stable during the pelleting process used and up to 81 days after pelleting. The absorption of the drugs in rainbow trout show different temperature dependencies. A quantitative comparison of our overall data from this work with individual results from earlier investigations was undertaken. Suggested withdrawal times for freshwater rainbow trout treated with these drugs are: for OTC, 90 days below 6°C, 70 days between 6 and 12°C and 60 days above 12°C; for TMP, 60 days below 8°C and 40 days above 8°C; for OA, 20 days at approximately 18°C.

    Notizen: In an attempt to create uniform nationwide guidelines for the management of all stages of endometrial carcinoma, and to limit the use of adjuvant radiation therapy in stage I disease to high-risk patients only, a protocol was developed by the Danish Endometrial Cancer group (DEMCA). From September 1986 through August 1988, 1214 women in Denmark with newly diagnosed carcinoma of the endometrium have been treated according to this protocol. This figure represents all endometrial carcinomas diagnosed in Denmark during this 2-year period. The primary treatment was total abdominal hysterectomy and bilateral salpingo-oophorectomy and no preoperative radiation therapy was delivered. In 1039 cases no macroscopic residual tumor and/or microscopic tumor tissue in the resection margins was found following surgery. Based on surgery and histopathology, these patients were classified as: P-stage I low-risk (grade 1 & 2 and 〈inlineGraphic alt="leqslant R: less-than-or-eq, slant" extraInfo="nonStandardEntity" href="urn:x-wiley:1048891X:IJG06010038:les" location="les.gif"/〉 50% myometrial invasion), P-stage I high-risk (grade 1 & 2 and〉 50% myometrial invasion, and grade 3), P-stage II and P-stage III (Group 1). Distribution was as follows: P-I low-risk 641 patients, P-I high-risk 235, P-II 105 and P-III (Group 1) 58 patients. No postoperative radiation therapy was given to P-I low-risk cases. P-I high-risk, P-II, and P-III (Group 1) cases received external radiation therapy. Recurrence rate at 68–92 months follow-up was 45/641 (7%) in P-I low-risk, 36/235 (15%) in P-I high-risk, 30/105 (29%) in P-II, and 27/58 (47%) in P-III (Group 1) cases. Fifteen of 17 vaginal recurrences in P-I low-risk cases were salvaged (mean observation time 61 months).
