Alteration in biochemical indices following chronic administration of methanolic extract of Nigeria bee propolis in Wistar rats

Objective: To determine the noxious attribute of methanol extract of Nigeria bee propolis at 300 and 600 mg/kg body weight in rats. Methods: Healthy Wistar rats were indiscriminately assigned into three groups (A-C) of five rats each. The control rats (Group A) were orally given 0.5 mL of dimethyl sulfoxide daily for 21 days while rats in Groups B and C were administered the same 0.5 mL dimethyl sulfoxide containing 300 and 600 mg/kg body weight methanol extract of bee propolis respective...

African natural products with potential antioxidants and hepatoprotectives properties: a review

Free radicals are highly reactive molecules generated during oxidation reactions which in turn initiate chain reactions resulting to cellular damage. There is substantial evidence implicating free radicals especially reactive oxygen species (ROS) in the etiology of more than one hundred degenerative disorders in humans including, arthritis, atherosclerosis, ischemia and reperfusion injury of many tissues, gastritis, diabetics, central nervous system injury, acquired immunodeficiency syndrome ...

Human Genetic Markers and Structural Prediction of Plasmodium falciparum Multidrug Resistance Gene (pfmdr1) for Ligand Binding in Pregnant Women

Te study aims to determine the association of malaria infection with ABO blood groups and genotype and also to detect point mutations at positions 86, 184, 1034, and 1042 of the Plasmodium falciparum multidrug resistance gene (pfmdr1) in blood samples collected from pregnant women attending General Hospital Minna. Out of 250 pregnant women screened, 39 (15.60%) had malaria infection. Prevalence was higher in women, during the third trimester (46.15%), genotype AA (64.10%), and O blood group (...

POLYETHYLENE GLYCOL – MODIFIED NANOCARRIER ENCAPSULATION OF DIMINAZENE ACETURATE IMPROVED HAEMATOBIOCHEMICAL RECOVERY IN TRYPANOSOMA BRUCEI BRUCEI INFECTED RATS

Abstract The enhanced safe drug delivery properties of polyethylene glycol (PEG) – modified  Diaminazene aceturate nanocomposite against Trypanosoma brucei infected rats were evaluated.  The drug conjugation was carried out by adding gold nanoparticle to PEG and diminazene aceturate. A group of infected rats were treated with free diaminazene aceturate, while other groups were treated with conjugated drug at different drug release time interval. Results revealed complete parasite clear...

Improvement of 2-Vessel Occlusion Cerebral Ischaemia/Reperfusion-Induced Corticostriatal Electrolyte and Redox Imbalance, Lactic Acidosis and Modified Acetylcholinesterase Activity by Kolavir

Abstract Disruption of electrolyte, redox and neurochemical homeostasis alongside cellular energy crisis is a hallmark of cerebral ischaemia and reperfusion injury.  This study investigated the effect of kolaviron (KV) on cortical and striatal cation imbalance, oxidative stress and neurochemical disturbances as well as neurobehavioural deficits in animals subjected to bilateral common carotid artery occlusion (BCCAO)-induced ischaemia/reperfusion injury. KV was administered at a dose of 100...

Purification and characterization of rhodanese from sprouted maize

Rhodanese, a cyanide detoxifying enzyme, was isolated and partially purified from malted maize (Zea  mays) using 85% ammonium sulphate precipitation and ion-exchange chromatography on CM- Sephadex C-25. The specific activity of the enzyme obtained was 5.07RU/mg protein with a yield of  9.6% and purification fold of 2.13. The Michaelis constant (Km) values of the substrates sodium  thiolsulphate (Na2S2O3) and potassium cyanide (KCN) were 80 mM and 300mM while their Vmax were  4.86 RU/ml/mi...

The potential protective effects of Diphenyl-diselenide (PhSe)2 on Mercuric chloride-Induced Nephrotoxicity in female wistar rats

ABSTRACT  Evidences have implicated free radicals or reactive oxygen species in mercuric chloride-induced nephrotoxicity. Diphenyl diselenide (PhSe)2, a simple and stable organoselenium compound, has been proposed as a good candidate for pharmacological and therapeutic purposes. This particular study was designed to investigate the protective effect of (PhSe)2 against mercuric chloride-induced nephrotoxicity.  In this study, 44 female Wistar rats with weights ranging from 125g and 180g were...

ACTIVATION OF CASPASE ACTIVITY IN RAT LIVER CELLS BY METHANOL EXTRACT OF GLORIOSA SUPERBA

Activation of caspase 3&9 by methanol extract of Gloriosa superba  ABSTRACT Mitochondrion is the key regulator in cellular energy homeostasis and plays a central role in determining cell apoptotic process; it is therefore regarded as a vital target for cancer chemotherapy. Cancer is obviously one of the most common areas where demand for alternative treatment is overwhelming. Many investigations revealed that bioactive compounds in natural products can act on mitochondria to trigger the per...

Caspase activation by methanol extract of Gloriosa superba on rat liver cells

Methanol extract of Gloriosa superba in this research was adopted due to the presence of photochemicals present in the plant. This photochemicals are known to act as antioxidants and anti tumor agent but it is not yet known if the activity of the plant is through the mitochondria mediated pathway, caspase activation and induction of apoptosis where up regulation is necessary
