Oral fructose-induced changes in blood ethanol oxidokinetic data among healthy Nigerians.

Reports on the influence of fructose on blood alcohol clearance have not always been consistent. Notwithstanding, information concerning the Nigerian population is yet to be documented. In this present study, ten consenting adults in apparent sound health, and who did not have any traceable history of alcohol or drug abuse were selected.

Thiocyanate levels of mainly dietary origin in serum and urine from a human population sample in Port Harcourt, Nigeria.

Thiocyanate levels were determined in serum and urine samples obtained from a human population sample of healthy non-smoking volunteers (aged between 14 and 30 years) of both sexes known to eat gari-based meals at least once a day. The samples were collected before and 3-4 hours after a gari- or rice-based meal. The values obtained before the test meals showed a wide variation, ranging between 39.

Whole blood cyanide levels of mainly dietary origin in a human population sample in Port Harcourt, Nigeria.

Whole blood cyanide levels in a human population sample of volunteers known to each gari-based meals at least once a day were determined. The most widely eaten cassava product in the area of research is gari. The mean blood cyanide obtained for healthy normal volunteers was 0.

The use of arginine analogues for investigating the functional organization of the arginine-binding site in lobster muscle arginine kinase. Role of the 'essential' thiol group.

1. The nature of arginine binding to lobster arginine kinase and the extent of its possible involvement with the ;essential' thiol group of the enzyme has been investigated with some inhibitory analogues of arginine. 2.

Effects of arginine and some analogues of the partial adenosine triphosphate-adenosine diphosphate exchange reaction catalysed by arginine kinase. Evolutionary divergence in the mechanism of action of a monomer and a dimer arginine kinase.

1. Both the monomer arginine kinase from lobster muscle and the dimer arginine kinase from Holothuria forskali catalyse the ATP-ADP partial exchange reaction at rates equal to 3 and 0.6% of the normal rate of transphosphorylation respectively.

Effects of anions on a monomeric and a dimeric arginine kinase.

1. Some effects of anions on the rates of phosphoarginine synthesis by monomeric (lobster) and by dimeric (Holothuria forskali) arginine kinases are reported. 2.

Evolutionary variation between a monomer and a dimer arginine kinase. Purification of the enzyme from Holothuria forskali and a comparison of some properties with that from Homarus vulgaris.

1. A purification procedure for the dimeric arginine kinase of the sea cucumber Holothuria forskali is described. 2.
