Abstract Background Waltheria indica is a multipurpose medicinal plant with abundance of phytochemical compounds. Antifertility effect of Waltheria indica Linn. root and leaves have been reported. However, the fraction responsible for this antifertility effect needs to be isolated for possible male contraceptive purpose. Therefore, this research was designed to isolate the antifertility fraction of Waltheria indica Linn. root (WILR) in an in vivo model using male Wistar rats. Crude ethanol extract of WILR was sequentially dissolved in hexane, dichloromethane, and ethyl acetate. Rats (n = 5) were administered with 200, 500, or 1000 μg/kg of hexane, dichloromethane, and ethyl acetate soluble extracts of WILR, while control received distilled water, daily for 15 days to determine the soluble extract with most antifertility effect. Thereafter, fractions were separated from dichloromethane soluble WILR extract by column and thin-layer chromatography. Rats (7 groups, n = 5) were administered with each of the fractions (DF1 to DF7; at 1000 μg/kg) to determine the fraction with the highest antifertility. Rats were thereafter sacrificed, and sperm parameters, reproductive hormones, testicular cholesterol, and protein were determined according to standard procedure. Histology of the testis was also done. Data were analyzed using ANOVA at p ≤ 0.05. Results Dichloromethane soluble fraction (500 μg/kg) significantly decreased sperm concentration (137.00 ± 9.85 to 107.00 ± 13.08 × 106 cells/mL), levels of testosterone (2.90 ± 0.65 to 1.50 ± 0.37 ng/mL), and FSH (0.08 ± 0.08 to 0.99 ± 0.08 IU/L). The dichloromethane soluble fraction also caused the loss of testicular interstitium and spermatogenic cells. DF5 significantly reduced sperm motility (92.00 ± 2.74 to 76.00 ± 5.48%) and LH (2.86 ± 0.52 to 1.47 ± 0.18 IU/L). DF5 also significantly increased levels of prolactin (1.22 ± 0.10 to 1.88 ± 0.48 ng/mL), testicular total protein (7.36 ± 0.35 to 8.54 ± 1.06 g/dL), and testicular cholesterol (34.17 ± 3.65 to 55.76 ± 6.08 mg/mL). Conclusion The results indicate that the DF5 is the bioactive fraction of WILR responsible for its antifertility effect. The possible antifertility mechanisms are through the reduction in sperm parameters, reproductive hormones, and histological changes in the testis.

AbstractApproved medications for alcohol use disorder (AUD) display modest effect sizes. Pharmacotherapy aimed at the mechanism(s) by which ethanol activates the dopamine reward pathway may offer improved outcomes. Basal and ethanol-induced accumbal dopamine release in the rat involve glycine receptors (GlyR) in the nucleus accumbens (nAc). Glycine transporter 1 (GlyT-1) inhibitors, which raise extracellular glycine levels, have repeatedly been shown to decrease ethanol intake in the rat. To further explore the rational for elevating glycine levels in the treatment of AUD, this study examined accumbal extracellular glycine and dopamine levels and voluntary ethanol intake and preference in the rat, after systemic treatment with glycine. The effects of three different doses of glycine i.p. on accumbal glycine and dopamine levels were examined using in vivo microdialysis in Wistar rats. In addition, the effects of the intermediate dose of glycine on voluntary ethanol intake and preference were examined in a limited access two-bottle ethanol/water model in the rat. Systemic glycine treatment increased accumbal glycine levels in a dose-related manner, whereas accumbal dopamine levels were elevated in a subpopulation of animals, defined as dopamine responders. Ethanol intake and preference decreased after systemic glycine treatment. These results give further support to the concept of elevating central glycine levels to reduce ethanol intake and indicate that targeting the glycinergic system may represent a pharmacologic treatment principle for AUD.

ABSTRACT Background: Researches on Chagas disease still use several animals and rats, due to size and susceptibility were preferred by many authors. Aim: To develop an experimental model of megacolon in rats inoculated with the strain Y of Trypanosoma cruzi. Methods: Thirty male Wistar rats were distributed in three groups inoculated with different inoculants: Group A: 600000, Group B: 1000000 and Group C: 1500000 blood trypomastigotes of T. cruzi. Animals were sedated intramuscularly at zero inoculation time (T0) and 60 days after inoculation (T60), to perform the barium enema in order to evaluate the dilatation of the different segments of colon in a comparative study of the measurements obtained, using a digital caliper. Evidence of infection was performed by blood smear collected from the animal’s tail 18 days after inoculation with observation of blood forms. Results: Comparing the intestinal diameter of the inoculated animals with 60,0000 trypomastigotes in the T0 of infection with T60 days after the inoculation, significant dilatation was observed between the proximal, medial and distal segments (p<0.01), indicating the establishment of the megacolon model. In addition, comparing intestinal diameter between the different segments, with in the T0 of infection and the T60 after inoculation, significant alterations were observed (p<0.05). Conclusion: The proposed model was possible for in vivo studies of alterations due to infection by T. cruzi and functional alterations of the colon. In addition, the changes manifested in the colon are not directly proportional to the size of the inoculum, but to the time of infection that the animals were submitted, since the animals inoculated with 60,0000 blood forms were the ones which presented the most significant alterations.

This study was performed to investigate the effects of aqueous Imperata cylindrica root extract on hepatic enzyme levels of alloxan-induced diabetic male Wistar rats. Forty (48) male wistar rats were divided into six groups consisting of eight animals each. Diabetes mellitus was induced using intraperitoneal administration 150 mg/kg body weight of alloxan and treatment was carried out for a period of 28 days. The first group served as the normal control and received only feed and water ad libitum. In Group 2 were diabetic rats without treatment with extracts. Group 3: diabetic rats treated with 200 mg/kg aqueous Imperata cylindrica root extract. Group 4: diabetic rats treated with 400mg/kg aqueous Imperata cylindrica root extract. Group 5: diabetic rats treated with 600mg/kg ethanol extract of aqueous Imperata cylindrica root extract. While Group 6 was diabetic rats treated with 0.5mg/kg Glibenclamide. The liver enzymes alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase levels were significantly (p < 0.05) changed in rats treated with Alloxan (150mg/kg b.w.) while treatment with the respective dosages of extracts significantly changed the levels of these parameters to normal. The results obtained indicate that the different doses of aqueous Imperata cylindrica root extracts were beneficial in mending damages to the liver caused by Alloxan monohydrate in the male wistar rats.
