- ItemCarpolobia lutea methanol root extract reinstates androgenesis and testicular function in cadmiumchallenged rats(Kampala International University, 2019) Ejike, Daniel Eze; Okpa, Precious Nwaka; Igbokwe, Ugochukwu Vincent; Moses, Dele Adams; Karimah, Mohammed Rabiu; Ayikobua, Emmanuel TiyoCadmium produces a wide range of biological dysfunctions in human and laboratory animals where it chiefly affects the testes, whereas, Carpolobia lutea has been known to have antioxidant benefits. This study was intended to investigate the effects of Carpolobia lutea root extracts on testicular hormone function in cadmium-challenged male rats. 48 male Wistar rats (170-190 g) were divided into six groups, each containing eight rats. Experimental animals in control (Group 1) were given 0.2ml/kg body weight (BW) of 10% tween 80; Group two were administered 1mg/kg BW of cadmium (i.p); Group 3 were given 1mg/kg BW of cadmium (i.p) + 100mg/kg BW extract; Group four took 1mg/kg BW of cadmium (i.p) + 200mg/kg BW extract while Group five and six got 100mg/kg and 200mg/kg BW extract respectively. The administration of vehicle and extract was conducted orally for six weeks. Testicular activity of 17 betahydrosteroid dehydrogenase (17β-HSD) and serum testosterone, luteinizing and follicle stimulating hormone (LH, FSH) levels were evaluated. Findings indicated that cadmium statistically (p<0.05) lowered testicular 17β-HSD activity and serum testosterone, LH and FSH levels when compared with those of the control group animals. However, Carpolobia lutea and its co-administration notably (p<0.05) elevated the activity of testicular 17β-HSD and levels of serum testosterone, LH and FSH. The study suggests that Carpolobia lutea extract plays a protective function in ameliorating testicular damage caused by cadmium in rats. This is probably due to the extract’s potential in the management of testicular dysfunction and fecundity in animals.

- ItemComparative Effects of Taurine and Vitamin E in Acetaminophen-Induced Oxidative Stress on Learning and Memory in Male Wistar Rats(Kampala International University, 2018) Iliya, Ezekiel; Ejike, Daniel Eze; Moses, Dele Adams; Karimah, Mohammed Rabiu; Adam, Moyosore Afodun; Sheu, Oluwadare Sulaiman; Okpanachi, Omachonu Alfred; Ayikobua, Emmanuel TiyoStress is an integral part of human life; stressful events exert deleterious effects on normal (physiological) functions, leading to the pathogenesis of diseases. Stress alters cognition, learning, memory and emotional responses, resulting in mental disorders like depression and anxiety. The comparative effect of taurine (TAU) and vitamin E (VIT E) was evaluated on learning and memory in acetaminophen-induced oxidative stress in male Wistar rats. Methods Twenty animals weighing (100-120 g) were divided into four groups (A-D) of five rat each. Animals in Group A (control) received 0.5 ml of distilled water only while those in Group B received 100 mg/kg of acetaminophen (ACE) only. Animals in Group C received 100 mg/kg of taurine plus ACE while those in Group D received 0.5ml of Vitamin E plus ACE. The administration was done once daily for sixty days during which learning and memory of the animals were assessed using elevated plus maze and novel object recognition for rats. Results Animals in Groups A, B, C and D were able to locate the closed arm at an average of 41.0 ± 13.2 s, 67.0 ± 13.5 s, 56.3±16.6 s and 32.2± 12.1 s respectively. During the training phase, the TAU + ACE animals explored the object presented to them more (67.99 %) compared with the control and other groups. The VIT E + ACE animals have the least percentage (51.94%) in exploring the novel object that was presented to them. During the consolidation phase, the control group explored the novel object presented to them more (75.62%) when compared with the other groups. The VIT E + ACE animals have the least percentage (64.15%) in exploring the novel object that was presented to the animals. Conclusion Available evidence from this study showed that animals in acetaminophen and control groups were able to explore the elevated plus maze faster than the taurine plus acetaminophen and vitamin E plus acetaminophen groups. It also demonstrated that TAU and VIT E have protective effects on acetaminophen-associated learning and memory impairment in male rats which might be elucidated by antioxidative effects, facilitation of neurotransmitter activity and secretion of the hormone corticosterone.
