The progeny of intact rats parents were exposed to emotional stress (Maternal separation stressn) and received an excessive amount of the blend of phytoestrogens (Ph) with mother's milk (1st group) from 3 to 22 day life. At the age of 10 months males received NP GdVO4 (0.33 mg/kg; 2nd group) or speman (158 mg/kg; 3rd group) with feed over the 70 days. Sexual behavior and fertility of males were investigated; the integrated indicator of reproductive potential (FI) was calculate and was estimated with the data of animals from group Control who were given vehicle (water). In the 1st group sexual behavior of males was characterized by accelerating sexual responses on female (double shortening of mounting and intromission latency) and a reduced ability to achieve ejaculation and to start the second round of copulations. The less females have been inseminated by these males (67% vs. 91% in Control group), but almost all became pregnant. As a result of the neonatal induction deterioration in the quality of male gametes intrauterine pregnancy loss increased more than twice, and the total number of foetus decreased (on 21%). These changes have led to a reduction of the male integrated indicator of reproductive potential (Fi) in 2.6 times compared with control animals. Using a NP GdVO4 rehabilitated male sexual behaviour indicators to Control group level, resulting in an increase in the number of fertilized females (up to 95%). In pregnant females decreased fetal losses (up to 15.2% vs. 18.1% in control, p<0,05) and increase in the number of fetuses (on 25%, p<0,05) that shows an improvement in the quality of sperm. The integrated indicator of reproductive potential (F1) increased to (8.3 ± 0.5) vs. (3.0 ± 0.3) u. in the 1st group (without treatment), that statistically higher than in groups Control and 3rd. Application of NP GdVO4 in rats with neonatal inductive pathology of the reproductive function and metabolic disorders normalizes sexual behaviour, the quality of sperm that restores male fertility and improves reproductive potential much more efficiently than the reference drug speman.","PeriodicalId":12306,"journal":{"name":"Fiziolohichnyi zhurnal","volume":"499 2 1","pages":"76-82"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77858253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This indicates about inhibition of arginase pathway of L-arginine metabolism, which is not significantly dependent on the type of disruption of spermatogenesis. The most significant changes have been observed in infertile men with leucocytospermia since white blood cells stimulate the formation of reactive oxygen species, induction and development of oxidative and nitrative stress in spermatozoa. Inhibition of arginase pathway of L-arginine metabolism has adaptive role, which is to limit bioavailabil- ity of L-arginine and to prevent excessive formation of NO in cytotoxic concentrations to sperm cells. It has been noted changes in serum concentrations of gonadotropin and sex hormones in men with various forms of pathospermia. The most expressed significant changes were in levels of follicle stimulating hormone and testosterone. The concentration of follicle stimulating hormone in patients with oligozoospermia caused by hypogonadism is twice higher and in patients with leucocytospermia in 1.8 times higher than in fertile men.

Using Ca²⁺-sensitive fluorescent dye Fluo-4 AM it was shown that the selected calix[4]arenes can suppress energy-dependent accumulation of Ca²⁺ by mitochondria. Accumulation of Ca²⁺ (80 jiM in the medium) accompanied by the growth of the fluorescent probe response from a conventional unit to a value of 1,57±0,04 (n=5). Calix[4]arenes C-97, C-99, C-107 falls fluorescent signal below the 0,88±0,08, 0,92±0,08 and 0,78±0,04 respectively. Thus, the selected calix[4]arenas lead to release of previously accumulated Ca2+ from mitochondria.

Analysis of fluorescence response NADH and FAD in a suspension of isolated mitochondria suggests that the effects of test compounds on the functional activity of the electron transport chain is associated with the initial stimulation of its 1-th complex and subsequent inhibition of Ca²⁺-dependent NAD- containing Krebs cycle dehydrogenases. Along with this, the use of photon correlation spectroscopy to assess changes in the volume of mitochondria (their hydrodynamic diameter) under the action of selected calix[4]arenes has shown that interference with the electron transport chain leads to changes in the osmotic balance between the matrix of the mitochondria and the external environment. The result is the growth of isolated organelles volume. In particular, the hydrodynamic diameter of mitochondria increased by 22±6 % and 34±8 % (n=5) in presence of C-97 or C-99. The conclusion was done about the advisability of further studies of the calyx[4]arenes effect on smooth muscle Ca²⁺-homeostase and mitochondrial bioenergetics in order to find effective modifiers of their func- tional activity.","PeriodicalId":12306,"journal":{"name":"Fiziolohichnyi zhurnal","volume":"1 1","pages":"27-36"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90919073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
