ABSTRACT
The proliferative potential of six primary ovarian carcinoids with different clinical outcome and histogenetic origin was examined immunohistochemically. The results showed that two cases with extremely high level of proliferative activity were associated with metastatic spread. In the remaining tumors, the examined factor was found to be at low level comparable with excellent prognosis of typical carcinoids in other locations. The preliminary results showed a possibility of a prognosis prediction according to typing of the ovarian carcinoids into two categories, i.e., tumors of low and intermediate malignancy. Topoisomerase II-alpha and Ki-67 are suitable markers giving valuable information about this phenomenon.

Nine strains of lactobacilli isolated from different parts of the intestinal tract of chicken were studied to determine their taxonomy and cultural characteristics. The experimental scheme included physiological and biochemical tests, morphological observations and determination of fermentation products from glucose. All isolates were heterofermentative organisms assigned to the Lactobacillus fermentum species. The relevance of intestinal lactobacilli to the nutrition of chickens was discussed.
