Tytuł:: RER and protamine-type proteins during Chara tomentosa L. spermiogenesis

Opis:: In Chara tomentosa during mid spermiogenesis (phases V, VI, VII) when the amount of nuclear protamine-type proteins increases, while the amount of histones decreases, in connection with chromatin remodelling, an extensive RER system filled with dark, fine-granular substance is observed. The intermembranous space of the nuclear envelope is filled with a homogenous substance which looks similar. The most extensive ER system can be observed in phase V, which is at the beginning of nuclear protein exchange. The results presented in this paper correspond with the earlier suggestion based on Chara vulgaris spermioge nesis studies, that ER takes part in a protamine-type protein synthesis, which enter a nucleus by endocytosis, through an inner nuclear envelope membrane.

Opis:: The present paper describes a synaptonemal complexes analysis carried out on oocytes collected from the ovaries of one-day-old puppies of domestic dog (Canis familiaris). Ovaries have been collected from 20 individuals altogether. Synaptonemal complexes were identified in oocytes originating from two puppies. It is concluded that the onset of canine female meiosis may occur earlier than previously reported.

Tytuł:: Is spermiogenesis common or rare in young male European bison aged 2 and 3 years?

Opis:: The aim of the present study was to determine how often spermiogenesis occurs in young male European bison up to 3 years old. Research was performed on sections of the testes and epididymes collected from 51 male bison aged 2-3 years. The animals were divided into 2 age groups: young males up to 2 years and young males up to 3 years old, with further separation into specimens with or without spermiogenesis. The animals were culled during the autumn-winter seasons in 1994-2008 (after rutting period) in the Bialowieża Primeval Forest. Spermiogenesis in the 2-year-old animals was a rare condition found in 16.7% of cases. However, at the age of 3 years more than half of the individuals examined (53.3%) had spermiogenesis. Young males up to 2 years old with spermiogenesis were characterized by a significantly higher body weight and their right testis also weighed more than the left testis of the animals without spermiogenesis, the difference being on the border of statistical significance. There was no significant differences in the body mass and weight of the left testis between older animals, up to 3 years old, with or without spermiogenesis. However, young males up to 3 years old with spermiogenesis were characterized by a significantly higher weight of the right testis than those without spermiogenesis.

Opis:: The area, perimeter and diameter of the seminiferous tubules in the European bison Bison bonasus (L.) were statistically higher in the animals with than in those without spermiogenesis, both among 2-year-old and 3-year-old males (p<0.001; p<0.001; p<0.001).
