Atef, M., S. A. Youssef, A. Ramadan, and M. Issa, "Ruminal excretion of sulfadimethoxine and sulfadimethyloxazole in goats and their influence on some enzyme activities and renal clearances.", DTW. Deutsche tierarztliche Wochenschrift, vol. 97, issue 5, pp. 203-6, 1990 May. Abstract

Five clinically health goats were injected with sulfadimethoxine and sulfadimethyloxazole in a single dose of 100 mg/kg b. wt. by intravenous route. Highest concentration levels of sulfadimethoxine and sulfadimethyloxazole in rumen were detected 1 hour following intravenous injection, then the concentration for both compounds declined at 12 and 8 hours post administration, respectively. In addition, both types of sulfonamide completely disappeared in ruminal fluid samples taken after 24 and 12 hours, respectively. The rate of acetylation for sulfadimethoxine and sulfadimethyloxazole were nearly similar and occurred to a high extent in ruminal fluid (22.95 and 23.72%, respectively). On the other hand, both tested drugs increased significantly the ruminal gas production from the first to eight hours after i.v. injection in goats. Changes in the serum enzyme activities (SGOT, SGPT and alkaline phosphatase) observed with sulfadimethoxine and sulfadimethyloxazole, and represented by a significant decrease in the activity of SGOT and SGPT level, alkaline phosphatase 4 hours sulfadimethoxine and in GOT/GPT ratio 24 and 48 hours after i.v. injection, respectively. The creatinine clearance was significantly decreased after 4 hours following the i.v. administration of sulfadimethoxine and sulfadimethyloxazole in goats.

Elsebai, "A randomized pilot study of high-dose epirubicin as neoadjuvant chemotherapy in the treatment of cancer of the bilharzial bladder", Annals of Oncology, vol. 2, no. 2, pp. 137-140, 1991. AbstractWebsite

Seventy-one patients with T2 and T3 bladder cancer were randomized to receive either two courses of epirubicin 120 mg/m2 i.v. push every 21 days pro-operatively, and four additional courses post-operatively (group I = 34 patients), or radical surgery (group 11 = 37 patients). At a median follow-up of 24 months (range 22 months to 38 months) 25 patients from group I and 14 patients from group II are still alive and disease-free. The estimated two-year disease-tree survival percentages were 73.5 and 37.9%, respectively (P = 0.05). After initial chemotherapy, resected specimens were subjected to histopathologieal study of chemotherapeutic effects. Necrosis was detected in 95% of cases with squamous cell carcinoma and in 57.3% of cases with transitional cell carcinoma. We conclude that the benefit which was obtained by pre-operative and post-operative chemotherapy with epirubicin is promising and may represent a significant improvement in the treatment of patients with carcinoma of the bilharzial bladder.
