[A case of an atypical course in pheochromocytoma].

A case of a young woman, 33 years of age, suffering from pheochromocytoma with an atypical course (proved pathologicoanatomically) with the clinical picture of shock hyperpyrexia (up to 41 degrees C), leucocytosis with a shift to the left is presented. The authors are of the opinion that the atypical course is probably due to the prevailing adrenaline secretion. The contemporary drug treatment of these cases is discussed.

[Microflora in corn silage].

A total of 1050 samples of maize silage taken at various depths on premises for storing ensilaged feeds. The presence of eight species of microscopic fungi was demonstrated in the sampled silage: Mucor, Penicillium, Aspergillus, Alternaria, Trichoderma. It was established that highest was the number of species in the surface layer of the ensilaged mass. Considerably less were the species at a depth of 1.5 m, and then again the number of species rose toward the ground layer of silage. It is believed that lactic acid fermentation and the aerobic conditions exerted mycostatic effects. It was also demonstrated that with the aging of silage fungal species of the Fusarium and Trichoderma genera disappeared.

[Distribution, species composition and toxicological characteristics of Fusarium fungi isolated from corn].

Studied were the occurrence and species composition of microscopic fungi of the Fusarium genus in maize, and the results are given of testing the toxicity of these fungi for chick embryos. A total of 357 strains of Fusarium fungi were isolated from 800 maize samples. Thirty-nine per cent of the sampled material accounted for the presence of F. moniliforme, 4,5--per cent--for that of F. graminearum, and 0.5 per cent--for that of F. culmorum. Most toxic for chick embryos proved F. graminearum. Less toxic was F. moniliforme, and least toxic--F. culmorum.

[Toxicological characteristics of mold isolated from corn silage].

Tested for toxicity were a total of 48 strains of pure cultures of the fungi: Aspergillus flavus, As. fumigatus, Penicillium, F. moniliforme, F. graminearum, Tr. lignorum. The methods of dermal tests, chick embryos, and feeding of young birds were employed. It was found that through dermal tests ten strains of the following species proved toxic: As. fumigatus, As. flavus, F. moniliforme, F. garminearum, and Trichoderma lignorum. Toxic for chick embryos were 13 strains of the same species. When young chickens were fed moulded silage toxic proved As. flavus and F. moniliforme. Chick embryos showed highest sensitivity to mycotoxins. The toxicity of the investigated strains varied depending on the methods employed, however, it was manifested to a different extent with all three methods.
