PHYTOCHEMICAL CONSTITUENTS, FREE RADICAL SCAVENGING PROPERTIES AND ANTIDIABETIC POTENTIALS OF METHANOL EXTRACT OF THE STEM (BARK) OF Alstonia boonei ON ALLOXAN-INDUCED DIABETIC ALBINO RATS

by

ABSTRACT This study was carried out to investigate the phytochemical constituents of the methanol extract of the stem (bark) of Alstonia boonei (MEAB), in vitro antioxidant activity of the extract and its possible antidiabetic and antioxidant potential using alloxan- induced diabetic rats as model. The qualitative analysis of the extract showed a wide range of … Read more

INTERACTION OF ANTIMALARIAL DRUGS (PYRIMETHAMINE AND SULPHADOXINE) WITH NORMAL AND SICKLE HAEMOGLOBINS: A UV-VISIBLE STUDY

by

ABSTRACT Crude haemoglobins were extracted from blood samples of identified individuals of normal (AA), sickle trait carrier (AS), and sickle (SS) by employing centrifugation techniques. The crude haemoglobins were dialysed at 4oC for 12hr against 50mM Tris-HCl buffer of pH 7.2. The effects of pyrimethamine and sulphadoxine on the haemoglobins in the presence and absence … Read more

EXTRACTION, PARTIAL PURIFICATION AND CHARACTERIZATION OF CELLULASE FROM Aspergillus fumigatus AND Aspergillus flavus IN SUBMERGED FERMENTATION SYSTEM USING BREADFRUIT HULLS AS CARBON SOURCE

by

CHAPTER ONE INTRODUCTION   Enzymes are the catalysts of biological processes. Like any other catalyst, an enzyme brings the reaction catalyzed to its equilibrium position more quickly than would occur otherwise. An enzyme cannot bring about a reaction with an unfavourable change in free energy unless that reaction can be coupled to one whose free … Read more

EFFECT OF ALKALINE STEEP AND AIR-REST CYCLE ON THE DEVELOPMENT OF SORGHUM PEROXIDASE ACTIVITY DURING MALTING

by

Abstract The effect of alkaline steep and air-rest cycle on the development of peroxidase activity during malting was investigated in sorghum variety, KSV8. Preliminary experiment showed that alkaline steep (test) and the distilled water steep (control) had germinative energy of 92± 2.87 % and 89± 0.57 % respectively. In regime II (sorghum grains steeped in … Read more

COMPOSITIONAL EVALUATION AND NUTRITIONAL POTENTIAL OF WINGED TERMITE (Macrotermes bellicosus)

by

ABSTRACT As part of the effort in combating hunger, this study was undertaken to determine the nutrient composition of an insect, winged termite (Macrotermes Bellicosus). This insect was high in protein (64.30g/100g), also it could be a good source of oil (19.93g/100g) and minerals, particularly calcium and potassium, at 975 and 203mg/100g respectively.  The proximate … Read more

COMPARATIVE STUDY OF THE EFFECTS OF AQUEOUS EXTRACTS OF MORINGA OLEIFERA AND VERNONIA AMYGDALINA LEAVES ON SOME BIOCHEMICAL INDICES IN ALBINO

by

ABSTRACT   A comparative study of the effects of aqueous extract of Moringa oleifera and Vernonia amygdalina on selected biochemical indices of prostate pathologies of male albino rats was investigated using thirty two adult male albino rats of average weight of 152g. Rats were randomly assigned into four groups of eight rats each with different … Read more

BIODEGRADATION KINETICS OF THE HERBICIDE, ROUNDUP BY SOME SOIL MICROORGANISMS

by

ABSTRACT Bacterial biodegradation of xenobiotics has been seen as one of the biological means of bioremediation of polluted site. This study was designed to isolate bacteria from soil and to evaluate their ability to biodegrade glyphosate which is a water soluble, non-selective herbicide used to kill weeds, especially annual broadleaf weeds and grasses known to … Read more

BIOCHEMICAL EFFECT OF ETHANOL SEED EXTRACT OF GARCINIA KOLA ON THE TRIACYLGLYCEROL (TAG) CONCENTRATION IN ALLOXAN-INDUCED DIABETIC RATS

by

CHAPTER ONE INTRODUCTION AND LITERATURE REVIEW BACKGROUND OF STUDY Plants are important in our everyday existence. They provide our foods, produce the oxygen we breathe, and serve as raw materials for many industrial products such as clothes, foot wears and so many others. Plants also provide raw materials for our buildings and in the manufacture … Read more

ANTIULCEROGENIC AND IMMUNOSTIMULATORY PROPERTIES OF THE AQUEOUS EXTRACT OF THE LEAVES OF Ficus capensis IN WISTAR ALBINO RATS

by

ABSTRACT Ficuscapensis leaves have always played a great role in preventing, controlling and alleviating various disease conditions. This study was aimed at validating the traditional use of the leaves of Ficuscapensisin folk medicine as an anti- ulcer and immunostimulatory agent. Diclofenac sodium (100mg/kg) body weight was administered intraperitoneally to induce ulcer. Seven groups(five rats each)were … Read more
