AIM: To determine toxicopathological and cytogenetic effects of Acetothioamide (ATA) on the female reproductive system. METHODS: Twenty albino female mice were divided equally into two groups: the first group (control) fed with diet pellet. The second group (treated) were inoculated intraperitoneally with a single dose of ATA (100 mg/kg Bw) for 15 days. All mice were sacrificed at the end of the experiment and blood was collected for evaluation of (FSH and LH), serum peroxy nitrate radical concentration. Cytogenetic analysis (chromosomal aberration, micronuclei, mitotic index and blast index) and the histopathological examination on ovary and uterus were done. RESULTS: ATA causes significant reduction (p < 0.0001) for FSH, LH and serum peroxy nitrate radical concentration among treated females. Oophoritis, pyometria, thrombosis and endometrial hyperplasia with granulomatous reaction were reported among treated females mainly in uterus tissue and ovary. CONCLUSION: ATA causes significant reduction for FSH, LH and serum peroxy nitrate concentration among treated females. Oophoritis, pyometria, thrombosis and endometrial hyperplasia with granulomatous reaction were the main pathological changes in uterus tissue and ovary among treated females.

Rabbits are among the most popular pets kept in the domestic environment, after dogs and cats. Therefore, more people have been seeking better information about their care, and finding greater availability of veterinarians qualified to treat these species. The result is increased longevity and more frequent diagnosis of various pathologies. Diseases that affect the female reproductive system such as neoplasias and hyperplasias are increasingly reported. In contrast, extra-uterine pregnancy is a disorder that is still poorly documented in rabbits in Brazil. The objective of this report is to describe a case of ectopic pregnancy with two fetuses in a 3-year-old rabbit, associated with endometrial hyperplasia succesfully treated by surgical intervention

Abstract Background Cystic endometrial hyperplasia-pyometra complex (CEH-P) is one of the most common uteropathies in bitches. In diseases with mild or obscure clinical signs and normal uterine size, a diagnosis based on a clinical assessment might be incorrect. The main aim of the research was to determine the morphological variables accompanying uterine diseases in bitches in microscopic evaluation. Consequently, the obtained results can be used to create a new classification system for uterine pathological changes during the development of the CEH-P, diagnosed by microscopic examination in bitches. Material for the study consisted of the uteri of 120 female dogs, aged 1–16 years, obtained during routine ovariohysterectomies. Macroscopic observation after a longitudinal incision of the uterine horns, allowed a preliminary classification of the uteri into research groups: control group (physiological uteri), and groups GI-III uteri collected form bitches with varying degrees of endometrial pathology. These preliminary classifications were then verified by histological analysis (H&E stain). Results The obtained results made it possible to determine and describe the prevalence (%) of pathological changes characteristic of the analyzed uterine diseases in the examined bitches. Histopathological analyses that were conducted have confirmed preliminary macroscopic evaluation for the control group, group GII (CEH), and group GIII (pyometra). In the uteri of the GI group, a severe congestion of the endometrium has been observed – this is typical of inflammation – which was not confirmed during histopathological examinations. However, these examinations revealed acute endometrial haemorrhage of varying severity. Conclusions Early reproduction disorders in bitches are, in general, not confirmed by clinical signs in the examined animals. The results show that during classification of typical morphological changes in the endometrium over the development of the CEH-P complex in bitches microscopic examinations are required. The obtained results indicate a frequent lack of consistency in the macroscopic assessment and histological analysis of the endometrium, observed in the analyzed uterine diseases, which in most cases is not followed by clinical symptoms. The presented classification of uterine diseases may be useful as a diagnostic tool in reproductive disorders in bitches and in examination in the field of basic research.

Introduction. The article presents a comparative analysis of the treatment of patients with combined estrogen-dependent pathology of female reproductive system: fibrocystic mastopathy and endometrial hyperplasia without atypia. The experience of treatment with an indole-carbinol-containing drug as monotherapy while using a levonorgestrel-releasing intrauterine system is presented.Aim. To evaluate the clinical efficacy of indolecarbinol in the treatment of patients with combined estrogen-dependent pathology of the female reproductive system.Materials and methods. The authors studied the responses to the treatment of patients with fibrocystic mastopathy and simple endometrial hyperplasia (n = 65) with the indole-carbinol-containing drug at a dose of 400 mg once daily for 12 months. All patients were divided into two groups: Group I (n = 32) – women who refused hormone therapy (indole-carbinol monotherapy); Group II (n = 33) – the use of indole-carbinol while using the levonorgestrel-releasing intrauterine system. Diagnostic methods: clinical and laboratory examination, ultrasound examination of mammary glands and pelvic organs, mammography, nipple discharge cytology at baseline and 6 and 12 months after the start of therapy. Before study group assignment to treatment, all patients underwent hysteroscopy with endometrial biopsy and histological examination. Descriptive statistics were used to evaluate the data: p-values below 0.05 were considered statistically significant.Results and discussion. The presented experience in treating women with combined pathology of the female reproductive system (fibrocystic mastopathy and endometrial hyperplasia without atypia) with the indole-carbinol-containing drug showed high clinical efficacy in mastopathy (relief of mastodynia (83.0 ± 1.6%), improvement of the ultrasound view of BI-RADS (66.1 ± 1.4%), reductions in mammographic density (66.1 ± 2.1%, p < 0.05)), high tolerability and satisfactory compliance. This drug combined with hormone therapy is recommended for the treatment of endometrial hyperplasia.Сonclusion. The use of indole-carbinol in the treatment of benign hyperplastic processes in mammary glands and endometrial hyperplasia is pathogenetically substantiated and shows high clinical efficacy

ABSTRACT The present investigation deals with the oestrogen-sensitivity of the female reproductive system during the neonatal period. Newborn female guinea pigs were used as test animals. At different times after a single subcutaneous injection of a physiological dose of 0.1 μg or an unphysiologically high dose of 10 μg 17β-oestradiol/100 g body weight, the RNA- and protein-synthesis was examined in the hypothalamic region, pituitary, cerebral cortex, liver, adrenal gland, ovary and uterus. With a physiological dose an increase in organ weight, protein content, RNA-and protein-synthesis was found only in the uterus. These alterations turned out to be dose-dependent. In addition to the findings in the uterus an inhibition of the aminoacid incorporation rate occurred in the liver following the injection of the high oestradiol dose. As early as 1 hour after the administration of 0.1 μg 17β-oestradiol an almost 100% increase in uterine protein synthesis was detectable. This result demonstrates a high oestrogen-sensitivity of this organ during the neonatal period. All the other organs of the female reproductive system such as the hypothalamus, pituitary and ovary did not show any oestrogen response. Therefore the functional immaturity of the uterus during post partem life is not the result of a deficient hormone sensitivity but is correlated with the absence of a sufficient hormonal stimulus at this time. The investigation on the effects of actinomycin resulted in different reactions in the uterus and liver. In contrast to the liver a paradoxical actinomycin effect was found in the uterus after treatment with actinomycin alone. This effect is characterized by a small inhibition of RNA-synthesis and a 50% increase in protein synthesis. The treatment of the newborn test animals with actinomycin and 17β-oestradiol together abolished the oestrogen-induced stimulation of the uterine RNA-and protein-synthesis. Consequently, the effect of oestrogens during the neonatal period is also connected with the formation of new proteins via an increased DNA-directed RNA-synthesis.

The aim of the study: was improvement of results of surgical treatment of patients of reproductive age eligibility with hyperplastic processes of endometrium (HPE) through the introduction of individualized treatment algorithm with the use of monopolar radio wave and hysteroscopic endometrial ablation. Materials and methods. The study included 62 women with non-atypical form of hyperplasia of the endometrium who were treated at the Center of General gynecology of the clinical hospital «Feofania», gynecological Department at the city maternity hospital № 3 of Kyiv. Depending on the age group, nature of the pathological process and method of treatment is randomized, the distribution of women according to groups: group 1 – 41 women's reproductive eligibility age netipichnaya forms of endometrial hyperplasia (PHEBA and KGEB), who were subjected to hysteroscopic monopolar endometrial ablation; group 2 – 21 female reproductive eligibility age netipichnaya forms of endometrial hyperplasia (PHEBA and KGEB), which was held radiowave ablation of the endometrium (RHAE). In the 1st group the age of patients ranged from 42 to 54 years, mean age was 49.9±4.7 years. In the 2nd group the age of patients ranged from 41 to 53 years, mean age of 51.6±4.3 years. Results. A comparative analysis of the techniques for hysteroscopic monopolar ablation and RHEE showed the fact that for RHEE used local anesthesia, while carrying out hysteroscopic monopolar ablation was necessary intravenous anesthesia. The duration of the hysteroscopic monopolar endometrial ablation was 28.6±5.5 min, RAE – according to the standard method – 44.3±0.3 min. When performing hysteroscopic monopolar endometrial ablation in 2 patients (3.7%) patients observed the signs of intravasation of fluid, increased blood pressure and tachycardia. This syndrome was successfully docked, but in the future, women have conducted a thorough examination. When you run RHAE intraoperative complications have been identified. Conclusion. 1. Women with netipichnaya forms of endometrial hyperplasia eligibility and late reproductive age who do not have reproductive plans as an alternative to hysterectomy, in the presence of contraindications or ineffectiveness of hormone treatment may be recommended or radiowave monopolar hysteroscopic ablation of the endometrium. 2. Monopolar hysteroscopic endometrial ablation is indicated for women with netipichnaya forms of endometrial hyperplasia, can be used in the presence of submucous form of uterine fibroids, postoperative scars on the uterus, but in the absence of adenomyosis II–III degree. The effectiveness of monopolar hysteroscopic endometrial ablation in women with non-atypical form of hyperplasia of the endometrium is 87.8%. 3. Women after endometrial ablation should be under observation for two years. The method of choice for dynamic monitoring of the condition of the uterus in women who underwent endometrial ablation is transvaginal ultrasound which should be performed after 1, 3, 6, 12 and 24 months of follow up. 4. In case of recurrence of hyperplastic process of the endometrium (bleeding, thickening of the M-mode echo according to the ultrasound) shows a hysteroscopy with a mandatory histopathological examination and verification of the diagnosis. Key words: endometrial hyperplasia, women eligibility age, women of reproductive age, ablation of the endometrium.

Currently, there are no standard approaches to monitoring patients with ovarian cancer (OC). While the role of ultrasound (US) has been identified in the primary diagnosis of OS, it is still controversial during the subsequent surgical treatment of OC. In world statistics, ovarian cancer is consistently among the four main localizations of malignant tumors of the female reproductive system, along with tumors of the breast, body and cervix.

In experimental studies on rats (males, females) at their infantile stage starting from 10 days, a potential delayed toxic effect of the antiviral drug Kagocel on the reproductive system was studied. The drug was administered for 12 days in a therapeutic dose and at a dose 10-fold higher than the therapeutic one. Reproductive safety was estimated after animals reached the reproductive age (2.5 months). It was found out that the drug, when administered in both doses, does not decrease the fertility of animals, does not induce morphological and pathological changes in the sex glands, and does not have toxic effect on the offspring. Obtained data characterize Kagocel as a preparation with a wide reproductive safety profile and show that it can be used in pediatric practice for infants.
