The aim of this study is to find out the effect of phenylhydrazine on creatinine clearance, hence GFR and the relationship between GFR and aldosterone. Sixteen 16 male Wistar rats weighing 200 – 250 grams were randomly divided into four groups namely: Group 1 – Normal control Group 2 - Hematinic group (Fes): fed normal rat chow + tap water + ferrous sulphate (using an oral gavage at 75mg/kg bw); Group 3 - Anemic -treated group (AFes): administered Phenylhydrazine (PHZ) intraperitoneally for two consecutive days to induce anemia at a dose of 40mg/kg bw + normal rat chow + tap water + ferrous sulphate at 75mg/kg bw. Group 4 (Anu) – Anemic control group: administered Phenlyhydrazine (PHZ) intraperitoneally at a dose of 40mg/kg of bw + normal rat chow + tap water (as in group one). After 15 days, blood and urine samples were collected into sterile sample bottles for analysis. There was a significant (P<0.01, P<0.01, P<0.05) increase in aldosterone levels between Anu, control, Fes and AFes respectively. There was a significant (P<0.001) decrease in control compared with Anu. There was also a significant (P<0.01, P<0.001) decrease in Fes with AFes and Anu. Anu creatinine clearance was also significantly (P<0.001) lower than AFes. Phenylhydrazine intoxication led to a reduction in creatinine clearance and an increase in aldosterone levels, confirming a negative correlation (r= 0.9956, P<0.01) between aldosterone and creatinine clearance. Also, ferrous sulphate tends to reduce the extent to which aldosterone levels increased hence narrowing the margine and or reducing the significance of the correlation.

This study aimed at finding out whether chronic consumption of oxidized palm oil affects the expression and/or activity of the renal transport proteins involved in the transportation of the electrolytes and glucose. 20 male Wistar rats weighing 120-140gms at the beginning of the experiment were randomly divided into four groups namely: control group, fresh palm oil diet-fed group (FPO); photoxidized palm oil diet-fed group (PPO), and Thermoxidized palm oil diet-fed group (TPO). The control group received normal rat chow while the oil-fed groups received 15% of the respective palm oil diet regimen in addition to tap water for 90 days. After 90 days, the animals were sacrificed, and blood samples collected while the kidneys were excised for biochemical analyses. Results showed that aldosterone levels in the PPO and TPO were significantly (P<0.01 and P<0.001 respectively) higher than that of control with the levels in the TPO being significantly (P<0.001) higher than PPO. Na+/K+ATPase and H+/K+ATPase activities were significantly (P<0.01; P<0.001, P<0.001) higher in FPO, PPO and TPO compared with control; with the Na+/K+ATPase activities in TPO being significantly (P<0.001 and P<0.05) than FPO and PPO respectively; while K+/H+ATPase activities in TPO were significantly (P< 0.001; P<0.001) higher than FPO and PPO respectively. SGLUT2 concentration in PPO was significantly(P<0.001) lower than control and FPO; and significantly (P<0.001) lower in TPO when compared with control and PPO and FPO. Therefore, chronic consumption of photo-and thermoxidized palm oil diets increases Na+/K+ATPase, and H+/K+ATPase activities, aldosterone levels but lowers SGLUT2 levels in Wistar rats.

Background: There are conflicting reports on the effect of coitus on seminal parameters. Similarly, studies believe hemi-orchidectomy improves the function of the contralateral testis while others observed no differences in the function of the contralateral testis. But there is paucity of information on the effect of coitus on seminal parameters in hemi-orchidectomized animals, and hence this study. Methods: Twenty (20) male Wistar rats were used for this study. The 20 male rats were divided into 4 groups of 5 rats each. Group 1 (both testes, no coitus); group 2 (both testes, with coitus); group 3 (hemi-orchidectomized, no coitus) and group 4 (hemi-orchidectomized, with coitus). Each male rat in groups 2 and 4 was cohabited with 2 females for three months after two weeks of the orchidectomy. Animals were sacrificed and their cauda epididymis and right testes dissected out for assessment of relevant parameters. Results: The results shows that seminal fluid parameters were not significantly different among the groups. There were no significant differences in body and organ weights among the groups. Group 2 rats (both testes/coitus) had a significantly reduced sperm count (p<0.05) compared with group 1 (both testes, no coitus). Sperm count was also significantly lower in group 3 (hemi-orchidectomized, no coitus) than in group 1 (both testes, no coitus) (p<0.05). Sperm count was significantly increased in group 4 (hemi-orchidectomy, with coitus) compared with group 2. Conclusion: We conclude that coitus may reduce sperm count in normal rats but does not have effect on sperm parameters in hemi-orchidectomized animals. However, orchidectomy increases sperm count in the contralateral testis.
