Biochemical studies on bilharzial and nonbilharzial hyperoxaluria: effect of pyridoxine and allopurinol treatment.

The urinary excretion levels of oxalic acid, calcium, kynurenic, and xanthurenic acids and serum pyridoxal and pyridoxal phosphate concentrations were determined for nonbilharzial and bilharzial hyperoxaluric patients with or without urinary stones. The effects of pyridoxine and allopurinol treatment were also studied. The different groups studied showed elevated levels of urinary oxalic acid, calcium, kynurenic, and xanthurenic acids as well as decreases in serum pyridoxal and pyridoxal phosphate concentrations.

Effect of new anticancer methanesulfonates on different biochemical parameters of mouse liver.

The comparative effect to two chemically related new synthesized anticancer drugs namely 3,3'-(methylimino) di(l-propanol)dimethanesulfonate(ester)diphenyl disulfonate, No. 838 D (NSC, 140-115) and 3,3' iminodi-l-propanol dimethanesulfonate(ester)p-toluene disulfonate, No. 864 T (NSC, 140-117), on liver DNA, RNA, lipids and glucose-6-phosphatase, after single 100 mg i.

A study on the etiological factors of bilharzial bladder cancer in Egypt. 6. The possible role of urinary bacteria.

A correlation was obtained between a positive nitrite test in urine and the severity of urinary bacterial infection. Bacteria isolated from the urine of bilharzial or bladder cancer patients were found to be rich in nitrate reductase activity. "Escherichia coli" was the most common microorganism isolated from these specimens.

Effect of dietary trans fatty acids on cholinesterase and monoamine oxidase activities in different organs of rats.

The effect of trans fatty acids and essential fatty acid deficiency upon the activities of cholinesterase and monoamine oxidase in livers, hearts, brains and lungs of rats was studied. This study was performed using three groups of male albino rats. Two out of these three groups were fed essential fatty acid low diets containing 10% hydrogenated coconut oil (HCNO) or margarine stock (MS, partially hydrogenated soybean oil) while the third group was fed an adequate supply of essential fatty acids through a diet containing 10% corn oil (CO).

Inhibition of erythrocyte and plasma cholinesterase by 5-hydroxytryptamine.

The inhibition of human erythrocytes and plasma cholinesterase (ChE) by 5-hydroxytryptamine in vitro was studied. Constants characterising this inhibition, namely the inhibition rate for red blood cells RBCs (2.5 x 10(4) (mol/l)-1 min-1) and plasma ChE (1.
