Ultrastructural studies of cytoplasmic droplets of various mammalian spermatozoa(bull, ram, rabbit, rat, and bat) have revealed only numerous membranous vesicles and tubules in their matrix. The simpl icity of the ultrastructure and lack of other organelles and inclusions in the droplet matrix led researchers to doubt suggestions that cytoplasmic droplets contain endogenous substrates for epididymal spermatozoa survival. Recently, however, biochemical and cytochemical analysis of cytoplasmic droplets in spermatozoa of different domestic animals showed a rather high activity of hydrolytic and glycolytic enzymes.In our study of interspecific variation in sperm morphology within the salamander family Plethodontidae, it was observed that spermatozoa of all examined plethodontid species have a characteristic cytoplasmic droplet. Cytoplasmic droplets of 16 species were examined with the light microscope and in addition, Plethodon qlutinosus was examined with the TEM.

The article discusses main issues of organizing activities for the treatment of stray and street animals in the city of Novosibirsk. The important role of successful solving the problem of stray animals in ensuring environmental comfort and safety of the urban population is noted. Definitions of the concepts “stray animals” and “street animals” are given, the differences between them are emphasized. The main regulatory and legal documents governing the handling of stray and street animals are listed. The ways in which domestic animals get into a stray state are described briefly. The results of the collection and analysis of information on the activities of shelters for stray animals in Novosibirsk are described. The information on the quantitative indicators of the shelters are given. Conclusions on how to solve the problem of stray animals, relying on the latest regulations are drawn.
