Background: Infertility is an important issue for couples that may cause various psychological and emotional problems. Female infertility disorders play a major role in approximately 50-80% of the ...causes of infertility in various areas in Nigeria. Moringa oleifera has been proposed as a plant with female fertility enhancement effects. The objective of this study was to assess the fertility-improving effects of ethanol extract of M. oleifera leaf and to determine the phytochemical components causing these effects by in silico analyses. Methods: The in vitro effects on fertility were evaluated using Drosophila melanogaster (fruit fly) because of its genetic similarities to humans. The copulation duration, mating latency, and the number of emergences from the fruit fly after mating were determined. Three doses (0.025%, 0.05%, and 0.1% w/w) of the M. oleifera ethanol extract were administered to three different groups, while a control group only received feed mixed with ethanol. For in silico studies, 62 compounds were obtained from the PubChem library by mining compounds from articles related to M. oleifera. Next, a ligand library was generated and docked against various targets of interest (estrogen, progesterone, kisspeptin, liver X, PPARG, and 15-PGDH receptors as well as 17β hydroxysteroid dehydrogenase and insulin-degrading enzymes) which have female fertility-enhancing effects. Results: The in vivo experiments showed that M. oleifera had no effect on copulation duration and mating latency, but interestingly, it enhanced the fertility/emergence of the treated fruit flies. In silico studies suggested that phytochemicals such as rutin, marumoside B, myricetin, and quercetin showed docking scores that may well support previous works on M. oleifera enhancement of female fertility. Conclusion: The results showed that M. oleifera can enhance fertility in female fruit flies.
Mammea africana, a medicinal plant, used in ethnomedicine for the treatment of malaria, diabetes, poisoning and inflammatory diseases was investigated for cytotoxic and genotoxic effects on the root ...meristem cells of Allium cepa. Onion bulbs were exposed to 2.5 mg/mL, 5mg/mL, and 10 mg/mL concentrations of the stembark extract for macroscopic and microscopic analysis. Tap water was used as a negative control and Methotrexate (0.1 mg/mL) as a positive control. There was statistically significant (p< 0.05) inhibition of root growth depending on concentration by the extract when compared with the negative control group. All the tested concentrations of the extract were observed to have cytotoxic effect on cell division in A. cepa. When compared to the control group, the extract-induced chromosomal abnormalities and micronuclei (MNC) forms in A. cepa root tip cells were substantial (p<0.05). Further inducing cell death, ghost cells, membrane damage, and binucleated cells was the extract treatment. These findings imply that the phytochemical components of Mammea africana root extract exert their cytotoxic and genotoxic actions on A. cepa.
The acute and sub-chronic toxicities of the leaf extract of Newbouldia laevis, an ethnomedicinal herb use in the management of diabetes mellitus was investigated. For the acute toxicity study, 10 – ...5000 mg/kg of the extract were administered orally to mice and obvious signs of toxic symptoms and mortality monitored for 24 h post extract administration. In the sub-chronic study, 302 and 604 mg/kg of the extract were orally administered daily for 90 days. Body weight changes as well as haematological and biochemical parameters were determined periodically. Qualitative phytochemistry was also conducted. Presence of flavonoids, saponins, tannins, reducing sugar, steroids, terpenoids, alkaloids and glycosides phytocompounds in the extract were detected. The oral LD50 was estimated to be above 5,000 mg/kg in mice. Ninety days oral administration of ethanol extract of N. laevis produced a significant (P<0.05) reduction in body weight at 604 mg/kg on the 31st day and at both 302 and 604 mg/kg on the 61st and 91st days compared to 5% Tween 20 vehicle control group. For liver function enzymes, the extract at both doses (302 and 604 mg/kg) produced significant (P<0.05) reduction in serum ALT enzyme activity at the 91st day with non-significant reduction in other liver function enzymes compared to vehicle control group. Non-significant changes were also recorded for haematological and kidney function markers. The results from this study provide evidence for safety profile of the ethanol leaves extract of N. laevis thus supportive of its validity in the use for treatment of chronic diseases like diabetes.
A BSTRACT Background: 2,4-Dinitrophenylhydrazine induces testicular toxicity and can result in reproductive dysfunction in male rats. Aim: This study investigated the effects of hydromethanolic leaf ...extract of Justicia secunda on phenylhydrazine (PHZ)-induced reproductive dysfunction in male Wistar rats. Settings and Design: Twenty rats (90–170 g) were grouped into five (A-E) ( n = 4) with the approval of the research ethics committee. Materials and Methods: Group A (control) received 0.5 mL of normal saline, Groups B to E received PHZ, PHZ + Astymin (0.5 mL), PHZ + J. secunda (0.2 mg/kg) and PHZ + J. secunda (0.5 mg/kg), respectively. All animals in Groups B to E received 2 mg/kg PHZ intraperitoneally for 2 days, and thereafter, administration of Astymin and J. secunda commenced in Groups C, D and E for 14 days using gavage. Statistical Analysis Used: The data were analysed using a one-way analysis of variance and the Bonferroni post hoc test. Results: Follicle-stimulating hormone (FSH) decreased significantly in PHZ, PHZ + Astymin and PHZ + J. secunda (0.2 mg/kg) and increased significantly in PHZ + J. secunda (0.5 mg/kg) than control. Luteinising hormone (LH) and testosterone significantly ( P < 0.001) reduced in treated groups than control. Total cholesterol, triglyceride, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol and very-low-density lipoprotein-cholesterol were significantly reduced in the treated groups than the control. Tumour necrosis factor alpha (TNF-α) significantly ( P < 0.001) increased in treated groups than in control. Testicular glutathione (GSH), glutathione peroxidase, catalase and malondialdehyde significantly increased in extract-treated groups compared to control. Superoxide dismutase significantly decreased in PHZ-treated group than in the control. Conclusion: PHZ administration caused testicular toxicity and altered biochemical markers, astymin treatment reduced male reproductive hormones, while J. secunda (0.5 mg/kg) increased FSH and LH, decreased TNFα levels and altered the concentration of testicular antioxidant markers. These alterations may be linked to the toxic effect of PHZ and could negatively affect spermatogenesis.
