Serotonin receptors have been found in several reproductive organs as well as in the central nervous system. Serotonin-binding sites have been demonstrated in duck ovarian follicles and the testis, hamster ovaries, human granulosa cells and mouse placenta. Local production of serotonin by the rat ovary, oviduct, uterus and testis has also been reported. We(More)
The morphogenetic function of the transient phase of cell death that occurs during blastocyst maturation is not known but it is thought that its regulation results from a delicate balance between survival and lethal signals in the uterine milieu. In this paper, we show that blastocysts from diabetic rats have a higher incidence of dead cells than control(More)
The course of histopathological alterations within jejunal graft architecture during the initial adaptation phase in the host body was investigated. Graft tissues were compared to the intestinal tissues of the recipients. This study demonstrates: (1) renewal of intestinal epithelial lining in the graft biopsies during initial hours after transplantation is(More)
Components of plant essential oils have been reported to have health benefit properties, including antioxidative, anti-tumour, antimicrobial, anti-stress, and immunomodulative activities. We examined the anti-inflammatory effects of thymoquinone, the active ingredient in the volatile oil of Nigella sativa seeds, and borneol, the active component of Salvia(More)
Ischaemic/reperfusion (IR) injury of the small intestine may lead to the development of multiple organ failure. Little is known about the morphological changes occurring in the organs during the subacute course of this syndrome. The objective of this study was to observe histopathological features and the role of apoptosis in the jejunal mucosa and lung(More)
It has been suggested that cyclosporin A (CsA) nephrotoxicity can be reduced by the concomitant administration of omega-3 fatty acids or vitamin E. The present study was designed to establish whether the effect of the above substances can also be demonstrated in rats with hereditary hypertriglyceridemia (HTG) whose sensitivity to the nephrotoxic effect is(More)
Serotonin is a neurotransmitter functioning also as a hormone and growth factor. To further investigate the biological role of serotonin during embryo development, we analysed serotonin localization as well as the expression of specific serotonin 5-HT1D receptor mRNA in mouse oocytes and preimplantation embryos. The functional significance of serotonin(More)
In a controlled study we compared the outcome of intracytoplasmic sperm injection (ICSI) performed by two different methods. The oocytes from 20 patients were equally divided into two groups and injected either by conventional ICSI using polyvinylpyrrolidone (PVP) or by a modified PVP-free ICSI procedure. While in the conventional ICSI method the(More)
Ischemic-reperfusion (IR) injury of the small intestine makes a serious complications associated with various surgical procedures and is related to changes in motility, secretory activity and structural alterations. Preconditioning can reduce range of this damage. The aim of the experimental study was to determine the influence of ischemic preconditioning(More)
The localization of fibrillarin and nucleolin in the nuclei of mouse two-cell, four-cell, and eight-cell embryos has been studied using immunofluorescent staining with specific antibodies. In all of these cleavage stages, both antigens were associated exclusively with the peripheral region of the nucleolus precursor bodies (NPBs). The original speckled(More)
