The role of angiotensin ll and oxidative stress in the spontaneously hypertensive rat.
Oxidative stress resulting from an imbalance between free radicals and antioxidants is considered to be an important etiological factor in the development and maintenance of hypertension. Angiotensin II (Ang II) has been ...
Determination of exposure of humans to selected mycotoxins with particular reference to aflatoxins.
Mycotoxins are poisonous secondary metabolites commonly produced by fungi and are involved in human disease conditions known as mycotoxicoses. There is evidence to show that food eaten by the rural Black population of ...
Endotoxaemia in intestinal dysfunction in experimental animals : intestinal ischaemia and hyperthermia.
Endotoxins or lipopolysaccharides (LPS), highly toxic component of the outer membrane of gram-negative bacteria, are normally present in the mammalian gut lumen.In this thesis, I investigated, in laboratory animals, whether ...
The synthesis of xanthone derivatives and their enzymatic conversion and inhibition of aflatoxin biosynthesis.
The biosynthesis of Aflatoxin B1 (AFB1) has been the subject of conflicting speculation and numerous reviews. The currently accepted scheme for the aflatoxin pathway is based on data obtained from feeding studies using ...
A cytotoxic evaluation of aflatoxin B1, zearalenone and their epoxide derivatives using human cell lines.
Since the discovery of mycotoxins in food, the thrust of biochemical and toxicological research has been carried out on animals which has proven to be uncoordinated and not easily extrapolated to humans. Over the last ...
The effect of vitamin B-6 deficiency on copper, zinc and iron balance in the rat.
In order to address the contradictory reports on the rat trace element status during a vitamin 8-6 deficiency, Zn, Cu and Fe balance was assessed over 8 weeks in 3 groups of young male rats. Group 1 was the control group ...
The value of morphological analysis in duodenal ulcer therapy
This study was designed to examine two premises: that the morphological "severity" of duodenal ulcers (DU) may influence the incidence of drug mediated healing and the morphological "quality" of healing after curative ...
Evaluation of the anthropometric parameters and fitness levels of prepubertal Indian soccer players.
Due to the lack of morphological data on prepubertal Indian male soccer players in South Africa, this study was undertaken on ninety male prepubertal subjects. The subjects were divided into three groups of thirty subjects ...
An investigation into the chemopreventive properties of an indigenous herb, Amaranthus lividus, using cancerous cell lines.
Chemoprevention may be defined as the inhibition, delay or reversal of carcinogenesis by dietary compounds or their derivatives. "Imifino" is a collective name for many wild plants used predominantly by rural people as ...
