This study evaluated the neuroprotective effects of MOF6 (isolated from Moringa oleifera leaves) and Trimyristin (isolated from Myristica fragrans seeds) on Acetylcholinesterase concentrations in cerebral cortices of rats with Sodium arsenite-induced neurotoxicity. Sixty-five adult male rats (150 g-250 g) were randomly divided into thirteen groups comprising of five rats per group. Groups 1 and 3 received physiological saline and 1 ml/200 g bodyweight of Olive oil respectively for 9 weeks. Group 2 received 20 mg/kg bodyweight of Sodium arsenite (SA) for 6 weeks and left untreated for another 3 weeks. Groups 4-5 received 20 mg/kg bodyweight of SA for 3 weeks followed by treatments with 5.0 and 7.5 mg/kg bodyweight of MOF6 respectively for 6 weeks. Groups 6-7 received 20 mg/kg bodyweight of SA for 3 weeks followed by treatments with 15 and 30 mg/kg bodyweight of Trimyristin respectively for 6 weeks. Groups 8-11 received 5.0 and 7.5 mg/kg bodyweight of MOF6; 15 and 30 mg/kg bodyweight of Trimyristin respectively for 9 weeks. Groups 12-13 received 7.5 mg/kg bodyweight of MOF6 and 30 mg/kg bodyweight of Trimyristin respectively for 6 weeks followed by co-administration of each extract dose with 20 mg/kg bodyweight of SA for another 3 weeks. Histological examination of cerebral cortices and biochemical analyses of Acetylcholinesterase concentrations were carried out in all rats. Computed data were analyzed using Microsoft Excel 2016 with statistical significance at p≤0.05. Histo-pathological evaluations revealed normal histo-architecture of cerebral cortices of all rats. Results showed statistically significant (p≤0.05) increases in Acetylcholinesterase concentrations in rats of Groups 1-10 and 12 compared with Group 2 (2.78±1.76 𝜇mole/min/g). 7.5 mg/kg bodyweight of MOF6 showed the best therapeutic and neuro-regenerative potential against SA-induced neurotoxicity.Conclusions: Our findings implied that MOF6 and Trimyristin reversed downregulation of Acetylcholinesterase concentrations in SA-induced neurotoxicity in rats; and possess neuro-protective and neuro-regenerative potentials.

Abstract Tramadol is a synthetic opioid analgesic used for moderate-to-severe pain structurally related to codeine and morphine, where their analgesic mechanism is a result of opioid and non-opioid mechanisms. This study was designed to evaluate the effects of Moringa oleifera leaves extract (MLE) on tramadol-induced testicular toxicity, sperm changes, testicular damage, and oxidative stress in male rats. Forty male albino rats were divided into four groups and treated for 4 weeks (group 1, as control; group 2, MLE; group 3, tramadol; group 4, MLE + tramadol). The relative body weight, relative testes weight, serum total testosterone, luteinizing hormone, follicle-stimulating hormone, sperm counts, vitality, total sperm motility, catalase, and superoxide dismutase activities were significantly decreased in tramadol-treated group when compared with the control group. In contrast, sperm abnormality, immotile sperm percent, testicular injury, and TBARS concentration in testes were significantly increased in the tramadol-treated group. In addition, histopathological examination for the tramadol-treated group has shown incomplete spermatogenesis, moderate degeneration in some seminiferous tubules with a significant decrease in the number of spermatogenic cells and depletion of Leydig cells. The administration of MLE with tramadol ameliorates the testicular toxicity, injury, sperm count, abnormalities, and oxidative stress induced by tramadol.

Tramadol, a broadly in recent years, is an effective analgesic agent for the treatment of moderate to acute pain. Its metabolites are excreted by the kidney which may cause nephrotoxicity. Moringa oleifera leaves are commonly used to provide herbal and plant-derived medicinal products especially in developing nations. The present study was carried out to determine the biochemical and histopathological changes in the kidney of tramadol-treated albino mice and to evaluate the possible protective role of Moringa oleifera leaves against tramadol-induced nephrotoxicity. Twenty adult albino mice were divided into four groups. Control group (group i) received daily intraperitoneal injection of normal saline only, group ii received oral dose of Moringa oleifera leaves extract (20 mg/kg/bw) for three weeks, group iii received daily intraperitoneal dose of tramadol (0.3 mg/kg/bw) for the same period, group iv, received daily oral dose of Moringa oleifera leaves extract, (20 mg/kg/bw) three hours before injecting intraperitoneal dose of tramadol (0.3 mg/kg/bw), for the same period. Blood samples were withdrawn at the end of the experiment for kidney function tests and specimens from the kidney were processed for histological study. No significant differences in the mean values of the kidney function tests were noticed between Moringa oleifera group and control group. However, there was highly significant increase in the mean values of serum, urea and creatinine in tramadol-treated group as compared to the control group. Although tramadol + Moringa oleifera group revealed significant difference in the mean values of urea and creatinine when compared with tramadol-treated group. So, Moringa oleifera leaves extract have been shown to attenuate the renal dysfunction, improve the renal architecture, with nearly normalization of serum urea and creatinine levels which indicate improvement of renal function. In conclusion, in the light of biochemical results and histological findings, co-administration of Moringa oleifera leaves lessened the negative effects of tramadol-induced nephrotoxicity; possibly by its antioxidant action. Further investigation of these promising protective effects of Moringa oleifera leaves against tramadol-induced renal injury may have considerable impact on developing an adjunct therapy aiming to improve the therapeutic index of some nephrotoxic drugs.
