The experiment was carried out to determine the gross and microscopic effects of arsenic on uterus of female Black Bengal Goats against control group in the Department of Anatomy and Histology, Faculty of Veterinary Science, Bangladesh Agricultural University, Mymensingh-2202. A total of twelve mature female Black Bengal goats were studied, six from arsenic affected areas of Mymensingh district and theother six from Hill Tracts of Bangaldesh which are arsenic free. Gross parameters show slight variations in the morphology (color and shape) and biometry (size and weight) of uterus of arsenic affected Black Bengal goats, but this variation was statistically insignificant (p>0.05). For microscopic study, permanent slide was prepared by Mayer’s Hematoxylin and Eosin stain method. In microscopic level, there were significant variations in arsenic affected group of goats compared to the control group. Arsenic affected group of goats show thickening of uterine horn (p<0.01), uterine gland is lower in amount and diameter(p<0.01), cervical villi length was smaller (p<0.01), cervical wall thickness was higher (p<0.01). This work may be the tip of the iceberg representing the full extent of arsenic exposure to female genital tract. DOI: http://dx.doi.org/10.3329/bjvm.v11i1.13175 Bangl. J. Vet. Med.

Interstitial cystitis (IC) is a chronic inflammatory disease characterized by bladder pain and increased urinary frequency. Although the C57BL/6J (B6) and FVB/NJ (FVB) mouse strains are commonly used as animal models for studies involving the urinary system, few reports have compared their lower urinary tract anatomy, despite the importance of such data. Our study aimed to characterize bladder function changes in FVB and B6 mouse strains with lipopolysaccharide (LPS)-induced IC, to understand mouse model-based bladder research. The bladder function parameters were measured by cystometrogram. Histological assay was examined by hematoxylin and eosin stain, Masson’s trichrome stain, and immunofluorescence staining. Results indicated that the two strains in the control group exhibited different bladder structures and functions, with significant anatomical differences, including a larger bladder size in the FVB than in the B6 strain. Furthermore, cystometry tests revealed differences in bladder function pressure. LPS-treated B6 mice presented significant changes in peak pressure, with decreased intercontraction intervals; these results were similar to symptoms of IC in humans. Each strain displayed distinct characteristics, emphasizing the care required in choosing the appropriate strain for bladder-model studies. The results suggested that the B6 mouse strain is more suitable for IC models.

This study aimed to investigate the impacts of the Trigonella foenum-graecum (T. foenum-graecum) seeds on the female gonad. A total of twenty local rabbits were used in this study; were divided into four groups (5 each): first group (G1) was considered as the control group. The second group (G2), third group (G3) and fourth group (G4) were fed daily1.5%, 3%, and 4.5% of T. foenum-graecum seeds respectively for 60 days (twice daily). At the end of the experiment, the animals were euthanized by diethyl ether (C2H52O). Then the abdomen was incised, and the samples of ovaries were collected and fixed by 10% neutral buffered formalin. The histological assessment was done with a paraffin embedding technique and the histological sections were stained with Hematoxylin and Eosin stain. The result showed that the numbers of primary and secondary follicles were significantly P< 0.05 decreased in G3and G4 compared with the control (G1) and G2. The numbers of Graafian follicles were significantly P<0.05 decreased G4 compared with other groups. The diameters of the primary, secondary, and Graafian follicles were significantly lower than the other groups. The thickness of the granulosa cell layer in G3and G4 were significantly lower than the other groups. The histological figures declared that the ovary of G2 was similar to that in G1. The histological sections of G3 and G4 were revealed marked cortical and medullary vascular congestion and focal hemorrhage; there were also marked follicular degeneration and cystic necrosis. The study concluded that the low concentration of T. foenum-graecum (fenugreek) seeds do not have any positive effect in terms of ovarian stimulation


Summary. Reproductive health is a priority in today’s global health care system. Among the factors of reproductive health disorders are female genital tract malformations. This pathology is mostly diagnosed with the onset of reproductive disorders at different ages of women, negatively affecting not only the reproductive but also the sexual functions of women, absorbing the quality of her life. The objective: to develop measures for the prevention of reproductive disorders in patients with female genital tract malformations based on the assessment of clinical manifestations and the frequency of reproductive disorders. Materials and methods. A retrospective assessment of reproductive disorders in 84 patients with a verified diagnosis of abnormalities in the development of the female genital organs was performed. The diagnosis was based on complaints, anamnestic data, the results of objective examination, clinical, laboratory and instrumental methods. The control group consisted of 25 women without abnormalities in the development of the female genitalia. Results. The mean age of the surveyed women was 27.6 ± 3.8 years. The duration of verification of the diagnosis of female genital tract malformations from the moment of the first visit to the gynecologist took an average of 3.1 ± 1.3 years. Of all the abnormalities in the development of the female reproductive system, 14.3 % were so-called «obstructive» abnormalities associated with impaired menstrual blood flow. Therefore, their clinical manifestation was earlier and more pronounced than in other patients and was manifested primarily by severe dysmenorrhea. Deviations in the age of onset of menarche occurred in 25 % of patients (OR =8; 95 % CI 1,019 – 62,798). In 73.8 % of women, the first reproductive disorders began during puberty. Dys menorrhea of varying severity occurred in 69.1 % of patients (OR = 7,064; 95 % СІ 2,527 – 19,744), of whom 70.6 % used medical treatment. The share of infertility among the women with anomalies in the development of the reproductive system was 19.1 %, pregnancy loss – 40.5 %. It was found that the risk of miscarriage in patients with congenital pathology of the female genitalia increases significantly (OR = 3,570; 95 % CI 1,125 – 11,325). 34.5 % of patients were diagnosed with genital endometriosis (OR = 6,064; 95 % СI 1,335 – 27,540). In 21.4 % of cases, abnormalities in the development of the female genitals were combined with congenital kidney disease. Conclusions. Prevention and predictability of reproductive disorders in patients with female genital tract malformations should begin with the pubertal period of the girl. A separate risk group consists of girls with pathology of the kidneys diagnosed prenatally. The basis for the prevention of reproductive health disorders in women with female genital tract malformations is the timely verification of congenital pathology and the development of a personalized system of management. The results of our research and the literature suggest that verification of the diagnosis of female genital tract malformations in women usually begins when patients have lost pregnancy or are experiencing infertility, while dysmenorrhea, menstrual irregularities that may occur in adolescence, often do not alert and do not become the basis for exclusion of congenital anomalies. That is why we believe that screening ultrasound examination of the pelvic organs in the presence of these disorders, it is advisable to conduct girls during puberty, if necessary – using 3D ultrasound and/or MRI.

SUMMARYClinical features, treatment and outcome were assessed retrospectively by means of a questionnaire in 174 patients in general practice whose vaginal swabs yielded bcta-haemolytic streptococci. These were compared with 96 patients whose swabs yielded no recognized microbial pathogens. Patients with group B streptococci did not differ in any of these parameters from the control group, but those with group A streptococci were more likely to have vaginal soreness, a purulent discharge. and to respond to anti-streptococcal antibiotics. Implications for laboratory reporting are discussed.
