Studies on the insect biological characterization are essential for understanding the ways of
ecological adaptation to the specifi c conditions of a particular region, and in practical terms, help
to predict the status of harmful or benefi cial insect populations. The main aim of the work was
to determine the biological characteristics of the development and distribution of species Sitona
lineatus L. on lucerne fi elds in the Republic of Moldova. As the result of the research carried
out, the largest number of specimens has been collected in the central part of the Republic of
Moldova (56%). The average number of S. lineatus L. population density was 5.03 ex./m 2 . The
maximum number counted 13-14 ex./m 2 . New data on the distribution of the species in the
country have also been updated and presented.

Phenotypical signs and biochemical composition of Saccharomyces cerevisiae CNMN-Y-
20 and Saccharomyces cerevisiae CNMN-Y-21 yeast strains are described in this article. The
presence of protein complexes with high content of indispensable amino acids and antioxidant
enzymes, as well as polysaccharides with predominance of β-glucanes allow us to recommend
these yeast strains for the utilization in biotechnology. The fi ndings are of interest for the
standard description of yeast strains offered as object for industrial purposes.

ASSESSMENT OF THE INCIDENCE OF STOMACH AND DUODENUM DISEASE
BY CYTOLOGICAL METHOD. Florea Natalia, Zatâc A. // Buletinul Academiei de Ştiinţe
a Moldovei. Ştiinţele vieţii.. 2012, No 3 (318), p. 147-151.
The purpose of the investigation was to assess the level of H. Pylori diagnostication by
a cytological method in various pathologies of the stomach and duodenum. Lot of research
has been investigated endoscopically in 210 patients of the Oncology Clinic. The cytological
investigation of bioptate prints sampled from stomach and duodenum is an adequate and
informative addition to histological investigation. It allows us to fi nd both detailed and malignant
processes and background processes and precancerous conditions.

Key words: Fibrogastroduodenoscopy - H. Pylori – stomach – duodenum – biopsy -
histological examination - cytological investigation.
