APPLICATION OF COMPETITIVE BINDING ASSAY METHODS TO SERUM VITAMIN D LEVELS IN HEALTH AND DISEASE

ABSTRACT Competitive Binding Assay methods have been used to determine the serum levels of 25- hydroxyvitamin D^ in healthy Ghanaians and patients suffering from cirrhosis of the liver and chronic renal failure. Although the assay followed fairly standard methods as used by several workers, an improvement in stability and sensitivity was obtained by the use of gelatin in the buffer; the final assay buffer being 0.02M phosphate buffer, pH 7 ,C with 0.1% gelatin. Though rachitic rat s...

Investigation of the Pancreatic Effect of Buccholzia Coricacea Formulated Diet in Sucrose Fed Pregnant Rats and their Offspring

ABSTRACT Several plants have been used in the treatment of various disorders without scientific basis. The present study examine the pancreatic effect of Buchholzia coriacea formulated diet in sucrose-fed pregnant rats and their offspring. Buchholzia coriacea seeds were obtained from Ogbete main market, Enugu state, identified, dried and grounded using a miller machine. 10% of the seed powder was used to formulate their diet. Thirty (240) adult female and six (6) adult male albino rats (180-2...

Hypolipidemic and Antioxidant Capacity of Methanol Leaf Extract of Kigelia Africana in Alloxan Induced Diabetic Albino Rats

ABSTRACT Diabetic mellitus is a metabolic disorder resulting from a defect in insulin secretion , insulin action or both . The deficiency of insulin leads to chronic hyperglycemia with disturbances of carbohydrate , fats  and protein metabolism. Kigelia Africana is a sausage tree known to have medicinal values. The aim of this work is to evaluate the hypolipidemic and antioxidant capacity of the plant , methanol leaf extract of kigelia Africana which was used for the study. The leaves were g...

Determination of Heavy Metals and Proximate Analysis in Some Selected Cereals

ABSTRACT This research was conducted to determine the concentrations of heavy metals and proximate composition of different cereals (maize, millet and rice). Two different samples each sold in two different markets (Ogbete and Gariki) in Enugu, were used for this work, using atomic, absorption spectrophotometer. The heavy metal screening of the cereal samples showed the presence of arsenic in the range of 0.456ppm-0.955ppm but was not detected in sample E and f which are the two different ric...

Relationship Between Anaemia, Glucose-6-Phosphate Dehydrogenase Deficiency and Oxidative Stress Among Malaria Patients Visiting ESUT Teaching Hospital, Enugu Nigeria

ABSTRACT Malaria is a significant public health problem in the world especially in in sub-Saharan Africa. One of the key contributory factors to the development and progression of malaria and its complications is oxidative stress, a condition characterized by increased production of free radicals or impaired antioxidant defence system. Glucose-6-phosphate dehydrogenase (G-6-PD) produces NADPH which intends regenerate reduced glutathione (GSH), an antioxidant which helps in the removal of free...

Hypolipidemic Propensity of Ethanolic Extract of Xylopia

ABSTRACT  Aim:  This  study  is  aimed  at  assessing  the  effect  of  Xylopia  aethiopica  fruit  on  the  lipid  profile  of Wistar rats. Methodology: The fruits of Xylopia aethiopica were obtained from new market in Aba, Abia State, Nigeria  and  were  authenticated.  They  were  air-dried  and  extracted  using  Soxhlet  apparatus  and ethanol  as  solvent.  The  median  lethal  dose  (LD50)  of  the  extract  was determined  using  standard met...

Weight Gain Reduction and Hypoglycemic Effects of Xylopi

Methodology:  The  fruits  of  Xylopia  aethiopica  were  air-dried  and  extracted  using  Soxhlet apparatus  and  ethanol  as  solvent.  The  median  lethal  dose  (LD50)  of  the  extract  was  determined using standard method....

Hybridoma Technology

  INTRODUCTION: Hybridoma technology is a method for producing large numbers of identical antibodies (also called monoclonal antibodies ). This process starts by injecting a mouse (or other mammal) with an antigen that provokes an immune response. A type of white blood cell, the B cell, produces antibodies that bind to the injected antigen. These antibody producing B-cells are then harvested from the mouse and, in turn, fused with immortal B cell cancer cells, a myeloma ,  to produce a hy...

Evaluation of Oxytocic Potential of Methanol Extracted sida acuta on Female Albino Rats

ABSTRACT Plants have long been a source of nutrition and therapy to man. The medicinal value of these plants lies in some chemical substances that produce a definite physiological action in the human body. This study evaluated the oxytocic potential of methanol extract of Sida acuta on female albino rats in vitro. Oxytocin was used as a standard drug though it is a biochemically synthesized hormone that act on distant hormone receptor to induce contractions. The methanol extract was prepared...

Garlic Bulb Prevents High Blood Pressure in Egg Yolk induced Hypertensive Rats

The aim of this study is to access the antihypertensivepotential of garlic juice in rats. To achieve this, 30 Wistar ratswere divided into three groups of 10 each. Rats in groups 1 and 2received aspecial prepared egg feed diet (24 egg yolkmixed with 1kg of normal rat diet) while those in group 3 received normalfeed diet and they served as the control group. Animals in group2 were administered 3 mL/100g body weight of undiluted garlicjuice simultaneously with the feeding. The animals were fedo...

Egg Yolk induces High Blood Pressure in Wistar Rats

Hypertension constitutes a major risk factor forseveral cardiovascular diseases such asatherosclerosis, heart failure, renal insufficiency,coronary artery disease and stroke. The risk factorincreases with age in both sexes. According to WHO,about one-third of the world’s population suffersfrom hypertension and the incidence has beenincreasing at a rapid rate due to life stylemodification. This study is aimed at investigating theeffect of egg yolk on blood pressure of Wistar rats. Toachieve ...

Effect of Consumption of Garri Processed by Traditional and Instant Mechanical Methods on Lipid Profile of Wistar Rats

Aim: This study focuses on the effect of consumption of garri processed by traditional and instantmechanical methods on the lipid profile of Wistar rats.Methods: Cassava samples were obtained from the International Institute of Tropical Agriculture(IITA), Ibadan and were processed using traditional and instant mechanical methods.

Air Freshener induced Oxidative Stress and Adveresly affects Immunity

Recently, the use of ‘sunlight’ air freshener in Nigeria is on the increase. Some people use airfreshener in the office, car as well as in their homes, thereby constantly being exposed to it withoutconsideration of its adverse effect on human health. This study is therefore aimed at assessing theeffect of “sunlight” air freshener on oxidative stress biomarkers. Thirty (30) Wistar rats were dividedinto three groups of ten each and kept in different rooms. Rats in group 1 were not expos...
