Selective cholesterol deposition in the kidney tissue of rats fed palm kernel oil diet.

Plasma and tissue lipids were determined in twenty-four rats fed on locally prepared 'Ogi' diet containing palm kernel oil (PKO), red palm oil (RPO) and mixture of both oils. Fasting blood sample was obtained from each animal by cardiac puncture under light ether anesthesia after feeding on different diets for twelve weeks. There were significant variations in the mean liver, kidney, spleen (p < 0.001, p < 0.03, p < 0.002) tissue weights in the different dietary groups compared with the corresponding control values. The plasma total cholesterol, triglyceride and lipoprotein cholesterol concentrations in the dietary group showed no significant changes when compared with the corresponding control values. The liver, spleen and heart total cholesterol concentrations were not significantly different from the corresponding values in the control group, but within group analysis showed significantly elevated total cholesterol in the kidney tissue of rats consuming PKO diet (p < 0.001). The total cholesterol level in rats consuming PKO diet was significantly higher than the corresponding concentration in those consuming the diet containing a mixture of PKO + RPO [p < 0.02] and control (p < 0.02) diets. There was also a significant increased in the kidney tissue cholesterol of rats fed RPO diet when compared with the corresponding control value (p < 0.05). The histological findings revealed no abnormality except in rats fed on PKO and RPO diets where nephrocalcinosis was found.

Plasma and semen ascorbic levels in spermatogenesis.

BACKGROUND: Conflicting reports on the mechanism of action of ascorbic acid level in male reproductive system exist and very little is known about the ascorbic acid status in Nigerian males with weak fertility. METHOD: Ascorbate that accumulates preferentially in the testis, the lipid and lipoprotein levels were determined in the plasma of Nigerian males. Twenty-seven (27) male with inadequate spermatogenesis (36+/-1.0) years, with mean value of 15.6+/-6.90 million/cm3 sperm count and fourteen (14) controls (34+/-0.6) years, with mean value of 108.0+/-25.42 million/cm3 sperm count were selected for this study. The anthropometric indices were also determined. RESULTS: There were highly significant decreases in sperm cell count, percentage motility and percentage vitality (p<0.001) in each case, while percentage morphologically abnormal sperm cells was significantly elevated (p<0.001) compared with the control values. There were significant decreases in the seminal and plasma ascorbic acid concentrations (p<0.001) in the males who had inadequate spermatogenesis compared with the control values. The plasma total cholesterol (TC) and body mass index (BMI) were not significantly different from the corresponding control values, but the plasma low density lipoprotein (LDLC) (p<0.001) and triglyceride (TG)(p<0.01) concentrations were significantly increased in all the patients. While the plasma high density lipoprotein cholesterol (HDLC)(p<0.001) was significantly decreased compared with the controls. The plasma lipid and lipoprotein levels did not demonstrate any definite pattern with the sperm characteristics. CONCLUSION: The decreased semen ascorbate level may play a significant role in the reduced sperm characteristics in these patients.

Abnormal serum alkaline and acid phosphatase isoenzymes in female breast cancer patients.

Serum total, different isoforms of both alkaline and acid phosphatases, liver function enzymes, calcium, inorganic phosphate, heamatocrit, white blood cells and platelet counts were determined in 50 female patients suffering from breast cancer. The serum total alkaline and total acid phosphatases within the breast cancer group were variable with significant elevation of both enzymes compared with the corresponding control values. The activities of alanine and aspartate transferases were higher than the control values, while the decreases in serum albumin and heamatocrit were statistically significant. In the breast cancer patients, the increases in the activities of both heat and urea labile alkaline phosphatases were significant. Similarly, in the patients, the tartrate-labile acid phosphatases activity was significantly elevated while the difference in tartrate resistant activity was not significant. In 9 patients (18%), both total alkaline and acid phosphatases were excessively raised when compared with the control. The increased activities of urea-labile and heat-labile alkaline phosphatases as well as tartrate-resistant acid phosphatases are suggestive of increased activities of osteoclast and osteoblasts associated with bone metastasis. A possible diagnostic importance of this observation deserves further investigation, using monoclonal antibody techniques.
