acetylsalicylic acid
Opis:: Acetylsalicylic acid (ASA) and α-2-pyrazylidene-α-cyano N-butyl acetamide (PD-101), a new antiaggregatory pyrazine derivative were tested for their genotoxicity in human lymphocytes in vitro using the sister chromatid exchange (SCE) technique. Both compounds were found to be inactive in inducing SCE in concentration from 1 µM up to 1000 µM. The agents displayed inhibitory effect on cell kinetics.

Tytuł:: Morphology and developmental potential of bovine parthenotes after spontaneous activation in vitro

Opis:: Spontaneous parthenogenetic activation of bovine oocytes in an in vitro maturation and fertilization system (IVM/IVF) is described. Altogether, 1403 follicular oocytes, collected by the aspiration method, were matured in vitro and then cultured without insemination in the same conditions as a group of inseminated oocytes. After 48-72 h of additional culture, 141 oocytes (10%) were found to be spontaneously activated. Morphological evaluation revealed that the number of blastomeres within parthenotes ranged from 2 to 16 cells, with a minority (15.7%) comprising of 9-16 blastomeres. According to a cytogenetic analysis, only 1.2% of the analysed parthenotes consisted of more than 9 cells. Parthenotes may not be distinguished from embryos produced in vitro and spontaneous parthenogenetic activation in an IVM/IVF system indicates suboptimal culture conditions. A group of non-inseminated oocytes should be included in each experiment to serve as a control. Spontaneously activated bovine parthenotes only occasionaly developed beyond the 8-blastomere stage in a common IVM/IVF system. The incidence of parthenotes interferes with the efficiency of in vitro embryo production but it is doubtful whether it lowers the pregnancy rate after transfer of IVF embryos.

Opis:: Five newly synthesised monophosphates of two pyrimidine acyclonucleoside series, namely 1-N-[(2’-hydroxy)ethoxymethyl] and l-N-[(l’,3’-dihydroxy)- 2’-propoxymethyl] derivatives of 5- and 5,6-alkylated uracils were tested in vitro for chromosome aberrations and sister chromatid exchanges (SCE). Metaphase plates were obtained via microculture of human lymphocytes from heparinized peripheral blood. The compounds were tested in doses: 10, 20, 40, 80 and 150 µg per mL of culture. The tested compounds induced mainly chromatid gaps, less frequently chromosome gaps. A low number of mitoses with chromatid and chromosome breaks, acentric fragments, dicentric chromosomes and exchange figures were also observed. The tested compounds in doses: 40, 80 and 150 µg per mL, doubled or tripled the percentage of cells with chromatid gaps and chromosome gaps as compared to the control. The percentage o cells with aberrations (excluding gaps) induced by the tested compounds in all doses did not exceed 2%. The tested compounds induced a higher number of SCE per cell but less than double frequency as compared to the control. SCE frequencies and replication index (RI) values varied depending on the examined compounds. For the highest dose of the tested compounds (150 µg per mL) a significant decrease in RI values was observed for l-N-[(2’-hydroxy)ethoxymethyl]-5,6-tetramethyleneuracil monophosphate and for l-N-[(2’-hydroxy)ethoxymethyl]-5,6-dimethyluracil monophosphate. So far, the results have indicated potential clastogenicity of all the tested compounds except acycloguanosine monophosphate.
