The effect of active schistosomiasis on the activity of some serum enzymes of hepatic origin has been studied in 46 male Egyptian patients with S. mansoni infections. These enzymes included total lactic dehydrogenase and its isoenzymes, 5'nucleotidase, B-glucuronidase, ornithine carbamyl transferase and sorbitol dehydrogenase. Samples were collected on admission, a week after the end of treatment and one month later. B-glucuronidase showed no change whereas ornithine carbamyl transferase, sorbitol dehydrogenase and 5'-nucleotidase showed elevated levels throughout the study. Total LDH was not significantly different on admission but increased significantly after treatment and returned to normal at follow up. Of the five LDH isoenzymes only LDH4 showed elevated levels. The significance of these findings in relation to conventional liver function tests is discussed.

A profile of biochemical tests was performed on 72 patients attending a lymphoma clinic. Urinary hydroxyproline excretion was increased in 24 cases at the outset; of these ten had positive clinical or radiological evidence of bone disease at that time, and in a further ten such evidence became available over the next two years. Hepatic involvement was detected among 9 patients at the initial examination. All of these, and a further five who developed liver involvement over the next two-year period had raised activity of serum 5'-nucleotidase. Total serum alkaline phosphatase was raised in 8 of the 9 patients with initial involvement, but only 1 of the 11 patients who subsequently developed hepatic disease; the heat stability test indicated the presence of the hepatic isoenzyme in these cases. Alkaline phosphatase was raised in 10 of the 20 cases with initial or subsequent evidence of bone disease, heat stability indicating the bone isoenzyme to be predominant. Serum ornithine transcarbamoylase was raised in only 7 patients with initial hepatic involvement, and the aminotransferases were not helpful in identifying lymphomatous involvement of the liver.

The effect of kolaviron, a mixture of Garcinia biflavonoid 1 (GB1), Garcinia biflavonoid 2 (GB2) and kolaflavanone, used in the treatment of various ailments in southern Nigeria on hepatotoxicity and lipid peroxidation induced by 2-acetylaminofluorene (2-AAF) in rats was investigated. The ability of butylated hydroxyanisole (BHA) to attenuate the toxic effect of 2-AAF was also examined. Kolaviron administered orally to rats at a dose of 100mg/kg body weight twice a day for 1 week before challenge with 2-AAF (200mg/kg feed) and continuously for 3 weeks at a single dose of 200mg/kg body weight reversed the 2-AAF-mediated decrease in final body weight and relative organ weights, especially the liver. BHA was administered at a dose of 7.5g/kg feed to the animals for 4 weeks. The extract decreased significantly the 2-AAF-mediated increase in the activity of aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transferase and ornithine carbamyl transferase by 58%, 62%, 60% and 67%, respectively. BHA elicited respectively 55%, 63%, 57% and 65% reduction in the 2-AAF induced-increase in the activities of these enzymes. Histological examination of the liver slices correlated with the changes in serum enzyme alterations. Similarly, kolaviron decreased the 2-AAF reduction of 5'-nucleotidase and glucose-6-phosphatase activities by 63% and 60%, respectively while BHA elicited 59% and 61% decrease in the activities of these enzymes. Simultaneous administration of kolaviron with 2-AAF inhibited microsomal lipid peroxidation as assessed by the thiobarbituric acid reacting substances (TBARS) formation by 66%. BHA produced a 64% reduction in TBARS formation. In the present study, kolaviron appears to act as an in vivo natural antioxidant and an effective hepatoprotective agent and is as effective as BHA.
