Abstract The article describes a method of preventing postpartum obstetric-gynecological diseases and improving cow reproductive function due to the increase of body nonspecific resistance with the application of electropuncture and biopreparation Prevention-N-C (Chuvash State Agrarian University, Russia) and Salus-PE (Chuvash State Agrarian University, Russia). The cows of the 1st group were injected three times 45-40, 25-20 and 15-10 days before calving intramuscularly at a dose of 10 ml/head with the biopreparation Prevention-N-C, and the cows of the 2nd group were injected according to the same scheme and the same term with Salus-PE, and the cows of the 3nd group electropuncture was performed on the Vocal-B device (BIORS, Russia) immediately after childbirth, three times, after 48 h. The use of biopreparations during critical periods of cow steeliness reduced the risks of subinvolution of the uterus, endometritis and mastitis in the postpartum period and increased the reproductive qualities of cows. It has been shown that after the use of Salus-PE, 100% of cows are fertilized, 60% of which are fertilized in the first sexual hunt, and 40% - in the second. The insemination index was 1.4.

Productive insemination of cows against the background of heat detection or synchronization of the estrous cycle within a relatively short time after the previous calving is the main factor that determines the productivity and profitability of dairy cattle breeding. Many obstetric and gynecological diseases often occur in the first 2 months of lactation. Postpartum obstetric and gynecological diseases of cows impair their reproductive qualities, which leads to prolonged anestrus, decreased fertility, and depletion of the body. Inflammatory processes of the female reproductive organs are accompanied by enhanced stress. The research aims to prevent diseases of the postpartum period and realize the potential of the reproductive qualities of cows by activating the nonspecific resistance of the organism with the Prevention-N-B-S biological preparation. Based on the performed studies, a method for the prevention of obstetric-gynecological diseases of the postpartum period and an increase in the reproductive function of cows by increasing the nonspecific resistance of the body with the biological Prevention-N-B-S is proposed. The newly designed biological preparation was for the first time used in cows of the 2nd experimental group intramuscularly at a dose of 10 ml 35-30, 15-10, and 10-5 days before the expected calving time, and the animals of the 1st experimental group were injected with Dorogov's antiseptic stimulator of fraction 2 in combination with eleovitum in a ratio of 1:9 60 days before the scheduled calving dates. It was found that in cows of the 2nd trial group (28.8±0.56 days), the first estrus began 5.8 and 14.4 days earlier than in the mates of the 1st trial group (34.6±0.93 days) and control (43.2±1.64 days) groups. There was a decrease in the conception rate in cows of the 1st (1.8±0.24) and 2nd (1.4±0.36) trial groups, in comparison with the control (2.6±0.26). The service period in the 1st (64.6±1.62 days) and 2nd (57.8±1.50 days) experimental groups decreased compared to the control group (89.2±3.02 days). In the first sexual estrus in the control, 1st and 2nd experimental groups, 2, 4, and 6 cows have become fertile, respectively. The use of biological in the critical periods of cow pregnancy reduced the risks of uterine subinvolution, endometritis, and mastitis in the postpartum period, and also increased the reproductive qualities of cows. The most expressed corresponding effect was obtained when using the biological preparation Prevention-N-B-S.

A growth in the number of deer and an increase in their productivity are closely related to the solution of the complex problem of reproduction and rational use of deer females. Significant damage to reindeer husbandry is caused by the barrenness of northern domestic deer, the level of which has been quite high in recent years. So, in the Republic of Sakha, on 01.01.2020, the number of domesticated reindeer was 152,068, of which female deer and heifers — 71,818, offspring per 100 females — 59, business yield amounted to 52 fawns per 100 females. The causes of infertility are very diverse, as the natural and climatic conditions of the breeding zones have a significant influence on the reproductive function of reindeer. In Yakutia, the main population of northern domestic deer is bred in mountain taiga and tundra natural-climatic zones, so there are about 55 thousand deer in the mountain taiga zone and more than 65 thousand deer in the tundra zone. In this regard, the study of the peculiarities of the postpartum period course in domestic reindeer females, its morphophysiology, and behavioral reactions depending on the natural and climatic conditions of breeding is of great importance.

The Brain

In mammals, the reproductive function is controlled by the hypothalamic-pituitary-gonadal axis. During development, mechanisms mediated by gonadal steroids exert an imprinting at the hypothalamic-pituitary level, by establishing sexual differences in the circuits that control male and female reproduction. In rodents, the testicular production of androgens increases drastically during the fetal/neonatal stage. This process is essential for the masculinization of the reproductive tract, genitals and brain. The conversion of androgens to estrogens in the brain is crucial for the male sexual differentiation and behavior. Conversely, feminization of the brain occurs in the absence of high levels of gonadal steroids during the perinatal period in females. Potential genetic contribution to the differentiation of brain cells through direct effects of genes located on sex chromosomes is also relevant. In this review, we will focus on the phenotypic alterations that occur on the hypothalamic-pituitary-gonadal axis of transgenic mice with persistently elevated expression of the human chorionic gonadotropin hormone (hCG). Excess of endogenously synthesized gonadal steroids due to a constant hCG stimulation is able to disrupt the developmental programming of the hypothalamic-pituitary axis in both transgenic males and females. Locally produced estrogens by the hypothalamic aromatase might play a key role in the phenotype of these mice. The “four core genotypes” mouse model demonstrated a potential influence of sex chromosome genes in brain masculinization before critical periods of sex differentiation. Thus, hormonal and genetic factors interact to regulate the local production of the neurosteroids necessary for the programming of the male and female reproductive function.

Today one of the main state tasks in the Russian Federation is to save people, which cannot be implemented without increasing the birth rate. Despite the fact that maternal mortality tends to decrease, bleeding remains one of the leading causes of death of women during pregnancy, childbirth and the postpartum period, so the fight against bleeding is one of the fundamental tasks in obstetric practice. The existing standards of step-by-step medical care for obstetric bleeding are successfully applied in practical health care, but the state of a woman’s reproductive function after the use of surgical hemostasis has not been sufficiently studied. This article presents an overview of a clinical case of reproductive function preservation in a 38-year-old woman after undergoing surgical hemostasis due to obstetric bleeding in the anamnesis.

Environmental toxicants, chemicals exhibiting with cholinotropics properties, and drugs – agonists and antagonists of M- and N-cholinergic receptors by acting on the developing brain of the fetus in the embryonic period of ontogenesis, cause a change the activity of the cholinergic mechanisms of the brain during critical periods of prenatal development with the subsequent disruption of the formation of different brain systems, primarily the ontogeny of nerve cells and brain neurotransmitter systems. These changes in the long term is correlated with neurobehavioral deficits from adult individuals, dysfunction of the reproductive system of adult offspring. The relevance of the study of prenatal effects of cholinergic factors on the central mechanisms of reproductive function, memory processes and learning during ontogenetic development of the organism due to the need of prevention and treatment of subsequent mental, behavioral, and sexual dysfunctions, and abnormal sexual behavior, infertility.

Abstract. Purpose. Examination of the thyroid and adrenal glands in the postpartum period in reindeer. Methods. The objects of the study were morphological changes of the thyroid gland and adrenal glands in the postpartum period. Measurements and weighing are carried out, the state of glands is described. At the same time studied the condition of the genital organs doe some morphological changes, bearing in mind the relation of these glands to the reproductive function. Results. The obtained data on thyroid weight pregnant doe averaged 5.7 g doe in parturition – 45 g, 22–28 days after parturition – 8.9 and 7.3 g (individual animals may be individual differences). The weight of the adrenal glands increases to 5 days of puerperium by almost 1.5 times (2.8–4.8), then decreases to initial values, the size of this organ changes slightly. Thyroid gland pregnant doe and killed in 1–3 days after birth contains different size follicles. In the adrenal glands, the glomerular zone of the cortical substance is thicker than that of the stele doe. On the fifth day of the postpartum period in the ovaries, the largest number of follicles was noted, at the same time, the mass increases and the structure and vascularization of the adrenal glands changes, and in the thyroid gland, on the contrary, the mass decreases, a large number of small follicles are found, which indicates its increased function. Thus, studies have shown significant changes in the size and weight of the adrenal glands and thyroid gland in the postpartum period in reindeer. The scientific novelty is the change in the size and weight of the adrenal glands and thyroid gland of deer in the postpartum period.

The research was aimed at determining the optimal dosage of "STEMB" (Embryonic Stimulant) for preventing delivery and postnatal complications, for which purpose 4 groups of 20 cows in each were formed. During the experiment, the animals in the studied groups were in similar feeding and keeping conditions, dry matter in the diet amounted to 44.95%. The animals in the experimental groups received "STEMB" subcutaneously three times in the 30 days period before delivery with the interval of 7 days in the following dosages: the first experimental group received 0.05 ml per 1 kg of live weight; the second experimental group received 0.075 ml per 1 kg of live weight; the third experimental group received 0.10 ml per 1 kg of live weight; the cows in the reference group did not receive the preparation. It has been determined that the dosage of "STEMB" equal to 0.075 ml per 1 kg of live weight prevents postpartum complications, shortens the labor and the postpartum period. The obtained data may be used for developing the reference criteria of using "STEMB" for correcting the reproductive function and preventing complications during delivery and postnatal complications.

The pituitary gland has an essential role in the maintenance of homeostasis, normal growth and reproductive function. Although pituitary tumours are rare in childhood and adolescence and are typically histologically benign, significant morbidity may result due to their location, mass effect and/or interference with normal pituitary hormone functions.1The early identification of pituitary tumours in children is necessary to avoid serious adverse effects on both physiological and cognitive outcomes as a result of pituitary hormone dysregulation during the critical periods of growth in childhood and adolescence. In this report, we review recent findings on the diagnosis, evaluation, treatment and molecular genetics of pituitary adenomas presenting in childhood.
