Anti-proliferative, Anti-angiogenic and Anti-inflammatory Effects of Moringa peregrina Leaf Extracts on Testosterone- Induced Benign Prostatic Hyperplasia in Rats

AIM

To investigate the potential anti-inflammatory and biochemical effects of Moringa peregrina leaf extracts on testosterone-induced benign prostatic hyperplasia (BPH) in rats.

METHODS

Six groups of rats (each group included 5 rats) were included in this study. The groups included: 1) the control group, 2) the testosterone-induced BPH group, 3) with 50 mg/kg bwt (bodyweight) oil-treated BPH, 4) with 100 mg/kg bwt. oil-treated BPH, 5) with 500mg/kg bwt. ethanol treated BPH and 6) with 1,000 mg/kg bwt. aqueous treated BPH group. Biochemical markers were measured to evaluate the effect of M. peregrina leaf extracts.

RESULTS

Our results showed a significant improvement in the thickness of epithelial cells of the BPH glandular tissues when treated with different M. peregrina extracts (p < 0.05). In addition, M. peregrina extracts showed anti-inflammatory, anti-proliferative and anti-angiogenesis effects on the BPH tissues by reduction of IL-6, PCNA and VEGF-A, respectively.

CONCLUSION

Our preclinical study concluded that M. peregrina leaf extracts showed a significant effect on BPH by reducing inflammation, proliferation, and angiogenic processes with no signs of toxicity.

Effect of partial replacement of alfalfa hay with Moringa species leaves on milk yield and composition of Najdi ewes

The present study was carried out to investigate changes in milk yield and composition of Najdi ewes fed 25 % Moringa oleifera (MOD) or Moringa peregrina (MPD) leaf diets as a supplement to alfalfa hay diet (AHD). Thirty ewes (average 55 kg, 2 years old) were randomly sorted into three experimental groups with 10 animals each and were fed for a 6-week period with these diets (AHD, MOD, or MPD). Diets dry matter, crude protein, and crude fiber were comparable, while fat, nitrogen-free extract (NFE), neutral detergent fiber (NDF), acid detergent fiber (ADF), metabolizable energy (ME), total phenolic, and antioxidant activity varied (p ≤ 0.05) between the diets. Feeding ewes with MOD increased (p ≤ 0.05) the milk yield compared to those fed AHD while milk composition was similar (p ≤ 0.05) between treatments. The concentration of malondialdehyde (MDA) in the ewes' milk and serum was lower (p ≤ 0.05) for MOD, while the total antioxidant capacity, catalase activity, and vitamin C contents were increased (p ≤ 0.05). The serum cholesterol and glucose of the ewes were lower (p ≤ 0.05) for those fed MOD. Moringa diets increased (p ≤ 0.05) average daily weight gain of lambs compared to those fed alfalfa diets. The results obtained showed that the inclusion of Moringa, especially M. oleifera, in the diet of Najdi ewes can improve milk yield and quality.
