Aims: The acceptability and accessibility of modern contraceptive drugs are limited especially in northern Nigeria. These contraceptives also have numerous side effects hence there is need to search for safe natural alternatives from medicinal plants. This research was aimed at evaluating the contraceptive effect of stem bark methanol extract of Vitex doniana in female albino rats. Place and Duration of Study: Department of Biochemistry, Faculty of Life Science, Kebbi State University of Science and Technology Aliero, Kebbi State, Nigeria. Between August 2019 to July 2020. Methodology: Vitex doniana stem bark was extracted with methanol and the extract was subjected to qualitative phytochemical screening. Acute toxicity (LD50) of V. doniana stem bark extract was determined using up and down method and anti-fertility effect was evaluated via (anti-ovulation, anti-implantation and serum hormonal assay). Results: The results for phytochemical screening showed the presence of alkaloids, flavonoids, tannins, steroids, glycoside, balsam and volatile oil. The LD50 of the extract was estimated to be greater than 5000 mg/kg as no mortality or any sign of toxicity are recorded within 14 days. The anti-fertility studies, methanol stem bark extract of Vitex doniana showed anti-ovulation activity through alteration of estrous cycle, changes in the histology of ovarian corpus luteum and decreasing number of follicles of extract treatment groups compared to control. Serum hormonal assay showed significant decrease (P<0.05) in oestrogen and progesterone level respectively in the extract treated groups compared to control group. Also, anti-implantation effect was observed in drug treated group (levenogesterel) and group treated with 400 mg/kg of V. doniana stem bark as there was no evidence of conception. Conclusion: The present study revealed that methanol stem bark extract of Vitex doniana is relatively nontoxic at acute dose and possess a moderate amount of antifertility agent.

Objective: This study was designed to investigate the sub-acute toxicity profile of hydro-methanol extract of Burkea africana  (BA) stem bark in rats. Methods: The stem bark of BA was extracted by cold maceration using 80% methanol. Twenty female albino rats were randomly assigned into four groups of five rats each. Group 1 (only distilled water). Groups 2-4 received the extract (100, 200, and 400 mg/kg) orally, once daily for 28 days. The rats were observed for signs of toxicity and the bodyweight (b.wt) of rats taken weekly. Blood samples were collected on day 28 for hematology and serum chemistry. Visceral organs were harvested for organ-somatic index and histopathology. Results: There were no toxicity signs observed and no significant (p< 0.05) change in body weight but the pulmo-somatic index was significantly (p< 0.05) higher at 400 mg/kg compared with the control and other treated groups. Significant (p< 0.05) increase in PCV, RBC, and MCV and significant (p< 0.05) decrease in MCHC, Total WBC count, neutrophils and lymphocytes were observed. Also, there were significant (p< 0.05) decreases in ALT, total protein, globulin, total bilirubin of test groups when compared with the control group. Urea concentration of test groups significantly (p< 0.05) increased when compared with that of the control group. Conclusions: BA stem bark extract can be said to have no deleterious effect on erythrocyte, but rather serve to improve erythropoiesis and also has no overt toxic effect on the visceral organs. Also the extract may have immunosuppressive and oxidative tendencies on prolong use.                                   Peer Review History: Received 12 January 2021; Revised 3 February; Accepted 25 February, Available online 15 March 2021 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Different parts of Vitellaria paradoxa plant have many applications in ethno-medicine. Some of the uses of this plant include treatment of diarrhoea and other GIT disorders. In this study the antidiarrhoeal activity of the ethanol extract of Vitellaria paradoxa was evaluated using three experimental models: Castor oil-induced diarrhoea; small intestinal motility and intestinal fluid accumulation (enteropooling) models in mice. Five groups of five mice were used for each model. Group one mice received 10 ml/kg of distilled water, while groups 2, 3, and 4 received 125, 250 and 500 mg/kg of the extract orally respectively. Group 5 mice received Loperamide 5 mg/kg orally. Oral median lethal dose (LD50) of the extract was determined using OECD (2008) Guideline 425. Phytochemical studies were conducted using standard procedures. The LD50 was estimated to be greater than 5000 mg/kg body weight and there were no signs of mortality or visible signs of toxicity in all the mice treated. Phytochemical screening revealed the presence of carbohydrates, alkaloids, flavonoids, saponins, tannins, triterpenes, steroids, cardiac glycosides and anthraquinones glycosides. Extract showed a dose-dependent anti-diarrhoeal activity by reducing stool frequency and consistency. The extract at the higher doses significantly (p < 0.05) inhibited GIT motility and castor oil-induced enteropooling, comparable to that of the reference control drug Loperamide. The study showed that ethanol stem bark extract of Vitellaria paradoxa possess anti-diarrhoeal activity and thus justifies its ethno-medicinal use in the treatment of diarrhoea.

The Impact

Objective: The objective of this work was to validate the traditional claim of the use of the stem bark of Berlinia grandiflora in treating liver problems by investigating the effect of its ethanol stem bark extract on maker liver enzymes in vivo.Methods: Groups of Wistar albino rats (6 in each group) were daily treated with CCl4 (2 ml/kg b.w., diluted with olive oil 1:1 v/v, intravenously), followed by oral administration of ethanol stem bark extract of Berlinia grandiflora (ESBG) at doses 100, 300 and 900 mg/kg b.w. respectively, 3 h after the administration of the CCl4. Serum biochemical parameters were measured 24 h at the end of the 7-day treatment period and compared to a group intoxicated with CCl4 (2 ml/kg b.w., diluted with olive oil 1:1 v/v, intravenously) alone.Results: Treatment of rats with ESBG (at doses 100, 300 and 900 mg/kg b.w. orally) reduced the impact of CCl4-induced hepatotoxicity on liver maker enzymes Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Alkaline phosphatase (ALP) and total bilirubin (TB), with the 900 mg/kg b.w. showing a significant reduction (p<0.05) compared to the group intoxicated with CCl4. The extract reversed the impact of the CCl4-induced hepatotoxicity by increasing the concentration of the serum Total protein (TP) and albumin (ALB), with the 900 mg/kg b.w. dose showing a significant increment (p<0.05) compared to the group intoxicated with the CCl4.Conclusion: The investigation of the effect of Berlinia grandiflora on CCl4 induced liver damage revealed that the ethanol extract of the stem bark of the plant was able to reverse the hepatotoxicity, with the 900 mg/kg b.w. dose showing a significant activity.

Xylopia Aethiopica

Impairment in testicular function can occur through perturbations in testicular oxidative stress markers and histology. Xylopia aethiopica (XE) is used to enhance fertility in males, but with information gap on its effect on testicular oxidative stress markers and histology. The present study assessed the effects of ethanolic stem bark extract of Xylopia aethiopica (EEXA) on testicular oxidative stress markers and histology of male albino rats. Sixty adult male albino rats (200g-250g) were randomly grouped into 4 (A-D) of 15 rats per group. The rats in the control group A (A1-A3) were administered per oral (p.o) with water (0.2 mL/day) for 15, 30 and 60 days respectively. The rats in groups B (B1-B3), C(C1-C3) and D (D1-D3) were administered p.o with EEXA (200, 400 and 800 mg/kg/day) for 15, 30 and 60 days respectively. The rats were anesthetized at the termination of EEXA administration and were dissected and testes removed. The testes were weighed and evaluated for oxidative stress markers and histology. Testicular weights were decreased in a dose and-time dependent fashion in EEXA-treated rats. Significant decreases in testicular superoxide dismutase, glutathione, catalase, and glutathione peroxidase levels with significant increases in malondialdehyde levels in a dose and time-dependent fashion were observed in rats administered with EEXA. Testicular histology showed cellular necrosis, degeneration and loss of interstitial tissues in rats administered with EEXA. This study observed that EEXA perturbed testicular oxidative markers and histology. Its use may impair testicular function.
