    Notizen: Of 317 patients with hypersensitivity to Hymenoptera stings forty had severe local reactions (SLR) only, fifty-nine reported severe local reactions before their first and seven after their last systemic reaction (SR). The probability to develop a life threatening systemic reaction when restung after a severe local reaction was calculated to be about 5%. In 80% of the patients with severe local reactions only, hypersensitivity to either bee or yellow jacket venom could be demonstrated by skin tests and/or RAST. A fair correlation of skin test and RAST results was observed. In patients with severe local reactions hyposensitization therapy with venoms is not generally indicated. In exceptional patients whose allergy is proven by skin tests or RAST and who are at a high risk of being restung, hyposensitization may be considered.

    Notizen: Summary After 12 oral applications of 80 mg/kg MNNG as a suspension in 30% aqueous ethanol at weekly intervals, 98 Sprague-Dawley rats died with multiple tumors of the forestomach after a medium latency period of 226 days. Histological examination showed generalized papillomatosis developing into keratinizing squamous cell carcinomas with infiltrative growth in 88/98 (89%) animals. Tumorigenic lesions in the glandular stomach ware only observed in 3/98 rats. In two of these animals, mucosal adenocarcinomas were found and in the third a leiomyosarcoma. In about 30% of the animals treated with MNNG, degenerative liver changes were found, especially single cell and focal necroses, cystic alterations, and bile-duct proliferations.

    Notizen: Summary The chemotherapeutic activity of five cytostatic drugs was investigated experimentally in monotherapy and in two-drug combinations, using Yoshida sarcoma cells implanted into the wall of the glandular stomach of Sprague-Dawley rats. In monotherapy, the antibiotic agent mitomycin C and the nitrosourea methyl-CCNU exhibited the highest cytotoxic activity in this tumor model. In combination therapy, the combination of these two drugs was superior to all the other therapeutic schemes tested. In general, the results demonstrate a marked superiority of combination therapy in comparison with monotherapy.
