Metabolic defects caused by treatment with the tetrahydropyridine analog of haloperidol (HPTP), in baboons.

Mounting evidence suggests that compromised cellular energy production is a major contributor to idiopathic and drug-induced degenerative processes. Our interest in neurotoxins have prompted us to examine in the baboon the effects of HPTP, the tetrahydropyridine dehydration product of haloperidol, on urinary chemical markers that reflect defects in mitochondrial respiration. Urinary dicarboxylic acid and conjugate profiles, similar to those seen in humans with inborn errors of mitochondrial metabolism and toxin-induced Jamaican vomiting sickness (JVS) were observed in the treated baboons.

Failure to thrive and its relationship to serum vitamin A levels and diet.

Serum vitamin A and retinol-binding protein (RBP) levels were determined in a group of 34 children between 1 and 4 years of age with failure to thrive and in 34 age- and sex-matched controls. Both groups of children were also assessed in respect of anthropometry and diet. Vitamin A levels in patients (0-32.

Nutritional status of primary school children with endemic goitre in Caprivi, Namibia.

The nutritional status of primary school children living in an endemic goitre area in eastern Caprivi, Namibia, was assessed by means of clinical, biochemical, anthropometrical and dietetic observations. An approximately 20 pc sample, consisting of 380 primary school children, aged six to 18 years and representing eight schools in the Cuando River area of eastern Caprivi, was included in the study. Their goitre prevalence of 34.

Dietary patterns and nutritional status in free-living older white men with established vascular disease.

Thirty-nine white men aged 51-84 years with established vascular disease were studied to investigate the effect of fish oil capsules on the regression of these lesions. This article deals with the baseline data of the study. The subjects completed a 7-day dietary record, weight and height were measured and a fasting blood sample was analysed for proteins, haematological values and certain vitamins.

Plasma lipids and fatty acids in urbanized Bushmen, Hereros and Kavangos of southern Africa (Namibia).

Thirty-nine urbanized ethnic Namibian people comprising 21 Bushmen (semi-urbanized), 7 Hereros and 11 Kavangos were assessed for plasma lipids and fatty acid (FA) composition. Total cholesterol and triacylglycerol concentrations were measured by enzymatic methods, and neutral lipid FA composition by gas-liquid chromatography. The results demonstrated that while total cholesterol concentrations were not significantly different, significant differences in triacylglycerol concentrations (P < 0.
