Reliability of histopathological examination and immunohistochemistry of a single biopsy for evaluation of endometrial health in Icelandic mares. Endometritis and endometrosis have been and still are the major reasons for infertility in mares. The diagnosis of endometritis can be based on cytology and microbiology, but endometrial biopsy is still the only way to diagnose endometrosis in the mare. Our study attempted to determine if a single biopsy using his-topathology and immunohistochemistry is sufficient to ascertain reasons for infertility in Icelandic mares. The objectives of this study were to examine the relationship between deviations in endometrial biopsies in terms of prostaglandin-endoperoxide synthase-2 (PTGS-2) and fibronec...
Modification of equine sperm chromatin decondensation method to use fluorescence in situ hybridization (FISH). Fluorescence in situ hybridization (FISH) is widely used in the study of chromosome structure and organization. Cytogenetic evaluation of chromosomes using FISH technique plays an increasingly important role in diagnosing karyotype changes in both somatic and reproductive cells. The aim of the study was to optimize the conditions of stallion sperm decondensation, which have a significant effect on the results of fluorescence in situ hybridization. Appropriate type and time of decondensation was chosen for the sperm of every stallion. It was found that decondensation performed using a preparati...
Application of primed in situ DNA synthesis (PRINS) with telomere human commercial kit in molecular cytogenetics of Equus caballus and Sus scrofa scrofa. Recently, molecular techniques have become an indispensable tools for cytogenetic research. Especially, development of in situ techniques made possible detection at the chromosomal level, genes as well as repetitive sequences like telomeres or the DNA component of telomeres. One of these methods is primed in situ DNA synthesis (PRINS) using an oligonucleotide primer complementary to the specific DNA sequence. In this report we described application of PRINS technique with telomere human commercial kit to telomere sequences identification. This commercial kit may be use to visualization of inte...
Comparison of specificity of human and horse leucocyte proteinases with synthetic peptide substrates. Highly purified horse leucocyte proteinases 1, 2A and 2B hydrolyze synthetic substrates which are decomposed also by human leucocyte elastase but they are unable to hydrolyze typical substrates of cathepsin G. Thus in distinction to other mammalian species horse leucocytes are devoid of cathepsin G and contain only elastases.
The interaction between some serine proteinases and horse leucocyte inhibitor. Horse blood leucocyte cytosol exhibits a broad inhibitory activity against serine proteinases. The purified inhibitor was exposed to investigated enzymes (trypsin, chymotrypsin, elastases and serine proteinase from S. aureus) for variable time and the products were analyzed by gradient polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulphate. The molar ratio I:E, association rate constants k on and inhibition constants Ki for the enzymes and inhibitor were determined. The examined elastases form stable, stoichiometric complexes with the inhibitor (Ki less than 10(-10) M), ...
Activity of delta(5)3beta-hydroxysteroid dehydrogenase and steroid hormones content in early preimplantation horse embryos. The activity of delta (5)3 beta-hydroxysteroid dehydrogenase was examined histochemically in 6 to 10 days aged horse blastocysts. A positive reaction was noted in the blastomeres of all embryos incubated in medium with substrate. Measurable amounts of progesterone, androgens and estrogens were found in blastocysts on day 8th. The presence of enzyme and hormones suggests that steroid hormone production takes place in very early preimplantation horse embryos.
