Abstract

To ascertain the comparative effects of ripe and unripe Lime (Citrus aurantifolia) on spermatozoa and gonadosomatic index evaluation in matured male Wistar rats; exploring the idea that both ripe and unripe Lime (Citrus aurantifolia) might or might not positively affect semen quality, crucial for male fertility. Twenty-eight (28) sexually mature male Wister rats, aged 9–10 weeks and weighing between 211.50g and 217.00g, were divided equally into seven groups (1 to 7); with Group 1 serving as the control and Groups 2 to 7 receiving 25%, 50%, and 75% concentrations of ripe lime juice (RLJ) and unripe lime juice (ULJ) respectively. The findings indicated that ULJ had a higher concentration (0.1mg/ml) compared to ripe lime RLJ at 0.08mg/ml, although both had approximately the same LD50 value of 1581.138mg/kg. RLJ, at different concentrations, adversely impacted the reproductive performance of rats, leading to decreased progressive motility, livability, sperm count, testicular size, and sexual drive. However, ULJ did not exhibit these effects. A 75% concentration of RLJ showed anti-prostatic activity, causing a reduction in prostate size, which was more pronounced than that of the same ULJ concentration. Importantly, both RLJ and ULJ did not have a significant impact on the sizes of the liver, spleen, heart, kidneys, and lungs, with these visceral organs maintaining normal sizes comparable to the control group (statistically, p>0.05).The findings suggest that RLJ or ULJ consumption, particularly at the highest concentration, may lead to alterations in reproductive performance, hence such consumption should be discouraged.

Abstract

Platelet aggregation, coagulation, and activation are crucial for hemostasis. Collagen treatment can impair hemostatic processes leading to bleeding disorders like thrombosis; vitamin C may mitigate these effects.  Hence, modulatory efficiency of vitamin C on collagen-induced platelet aggregation and dysfunction was investigated. Thirty (30) Wistar rats (135g-155g) were divided equally into; Group 1 (Control), Group 2 (Collagen-induced), and Group 3 (Collagen + Vitamin C treated). Platelet aggregation, prothrombin time, bleeding time, fibrinogen levels assessed coagulation and platelet function. Thromboxane B2 and P-selectin levels measured platelet and endothelial activation. Platelet count, mean platelet volume (MPV), platelet distribution width (PDW), and plateletcrit (PCT) evaluated platelet production and size variability. Statistical significance was set at p < 0.05. Group 2 exhibited higher platelet aggregation, prolonged prothrombin and bleeding times and elevated fibrinogen, thromboxane B2, and P-selectin levels, along with increased platelet count, MPV, PDW, and PCT, compared to Group 1. Group 3 showed significant reductions in all these parameters compared to Group 2 (p < 0.05). Vitamin C demonstrated significant modulatory effect on collagen-induced platelet aggregation and dysfunction which suggests that vitamin C may have therapeutic potential in mitigating platelet dysfunction and coagulation impairments associated with collagen-induced pathophysiological conditions.
