RESUMO
BACKGROUND: Previous studies have shown that morphine negatively effects male fertility while Phoenix dactylifera (dates) could cure male infertility by the exhibition of antagonist effects. This study was conducted to assess the possible ameliorating effects of dates on the histological features of morphine-induced male rat reproductive organs. MATERIALS AND METHODS: Adult male Sprague Dawley rats age 7-9 weeks old, 200-250 g body weight (BW) were divided into six rats per each group: Group 1, force-fed with distilled water, 1 ml/kg BW for 35 days (control); Group 2, intramuscularly (IM) injected with morphine, 20 mg/kg BW for 7 days followed by force-fed with distilled water for 28 days; Group 3, force-fed with distilled water for 7 days followed by crude P. dactylifera extract, 200 mg/kg for 28 days; Group 4, injected (IM) with morphine, 20 mg/kg BW for 7 days followed by force-fed of crude P. dactylifera extract, 200 mg/kg for 28 days. Rats were sacrificed on day 36. The seminal vesicle (SV) and prostate gland (PG) were removed and fixed before histological processes. RESULTS: In morphine-treated rats, the SV showed the absence of honeycomb-like appearance with flattened columnar cells while in the PG, eosinophilic secretion was noted to be absent from glandular lumina as compared to the control group. Administration of P. dactylifera extract in Group 4 showed improvement in histoarchitecture of the SV and PG with complex mucosal infoldings and glands luminal filled with secretion. CONCLUSION: P. dactylifera extract has a protective effect against the adverse effects of morphine on the male rat reproductive organs.
RESUMO
Anastatica hierochuntica L. (A. hierochuntica) is a desert plant consumed by people across the globe to treat various medical conditions. This review is aimed at providing a summary of the scientific findings on biological activities of A. hierochuntica and suggests areas in which further research is needed. This systematic review was synthesized from the literature obtained from the following databases; PubMed, Science Direct, Web of Science, Ovid Medline, Scopus, Google Scholar and WorldCat. Previous studies have indicated that the methanolic and aqueous extracts of this plant have antioxidant, antifungal and antimicrobial activities. It was shown to have the ability to activate phagocytes and to possess microbicidal activity, thereby causing increased resistance to infection. Both methanolic and aqueous extracts of this plant were also demonstrated to have a hypoglycaemic property, whilst the methanolic extract significantly exhibited hypolipidaemic effects in diabetic rats. Moreover, the methanolic extract of A. hierochuntica has been suggested to have hepatoprotective properties. This is supported by its ability to significantly decrease transaminase and alkaline phosphatase activities in alloxan-induced diabetic rats. Besides, this desert plant exhibited anti-inflammatory, anti-melanogenic and gastroprotective activities. Even though A. hierochuntica is widely used, studies on this plant are still scarce, thus its reputed biological activities and medical benefits require critical evaluation. Before A. hierochuntica can be used clinically, further studies need to be conducted to increase our understanding of the effects of this plant, its constituents, and possible mechanisms of action.
