Ovaries of heteropterans consist of telotrophic meroistic ovarioles that are composed of apically located tropharium and basal vitellarium, containing developing oocytes. The tropharium (trophic chamber) houses trophocytes (nurse cells) that are connected with the centrally located trophic core. The organization of the heteropteran tropharia is highly(More)
The sensitivity of the available methods of apoptosis detection in lymphocyte cultures was tested. Cells were preincubated with genotoxic agents: hydrogen peroxide (0.2 mM; 20 min.) and benzo[a]pyrene (40 microM; 90min.), and then cultured for 36h in the presence of a lectin (PHA-M; 1% v/v) and one of the following potentially antimutagenic agents:(More)
An antimutagenic activity of fluphenazine, todralazine, anthocyanins and alkylresorcinols was established in a battery of short-term cytogenetic tests. One of the possible mechanisms of their antimutagenic action could be an increase in apoptotic elimination of heavily-damaged cells from a culture. In this paper we provide data on quantitative estimation of(More)
An oocyte nucleus contains different extrachromosomal nuclear domains collectively called nuclear bodies (NBs). In the present work we revealed, using immunogold labeling electron microscopy, some marker components of interchromatin granule clusters (IGCs) and Cajal bodies (CBs) in morphologically heterogeneous oocyte NBs studied in three hemipteran(More)
