The aim of the study was to investigate the e...

Effect Of Cellgevity®, A Glutathione-Enhancer Dietary Supplement, On Streptozotocin-Induced Type-2 Diabetes And Nephrotoxicity In Rat

ABSTRACT Background: Diabetic nephropathy (DN), a diabetes-induced nerve damaging effect on the kidney structure and function due to hyperglycaemia is a major microvascular complication. Hyperglycaemia causes uremia, hypercreatininemia, declined glomerular filtration rate, and decreased levels of serum protein and albumin. This condition leads to progressive decline in renal function resulting in renal insufficiency and End-Stage Renal Disease. The prevalence of DN in Africa has increased sig...

Amikacin Treatment With or Without Aminophyllibe in Neonates With Suspected Sepsis at Korle-BU Teaching Hospital: A Pharmacokinetic and and Pharmacodynamic Study

ABSTRACT Background: Sepsis is a major cause of death among neonates. In neonates, symptoms of sepsis are often non-specific and diagnosis requires a high index of suspicion. Thus, the role of additional diagnostic markers is important. Amikacin is used as first-line treatment of neonatal sepsis and it is usually co-administered with aminophylline in preterm neonates in Ghana. Amikacin dosing is well established, however, optimal effect requires specific dose titration and maintenance therap...

Hypoglycemic Effect Hydroacetone Extracts of Treculia africana Decne Root and Stem Bark in Alloxan-Induced Diabetic Rats

ABSTRACT The main objective of this study was to compare the hypoglycemic activity of ethylacetate soluble portion of aqueous acetone extract of the root bark (EtOAcfr TARB) and stem (EtOAcfr TASB) back of Treculia africana Decne in diabetic rats and also to characterize the ultraviolent and infrared spectra of an isolated constituent. Oral administration of the EtOAcfr TARB reduced fasting blood glucose level by 28.6% in 144hrs and 15.9% at 240 hrs in alloxan (100 mg/kg) induced rat of five ...

STUDIES ON THE ANTIVENOM ACTIVITIES OF THE AQUEOUS EXTRACTS OF PAULLINIA PINNATA AND DETARIUM MICROCARPUM AGAINST ECHIS CARINATUS (CARPET VIPER) VENOM

In rural savannah areas of Nigeria, Echics ocellatus (Carpet viper) is responsible for high incidence of snakebite morbidity and mortality. The snakebites are commonly treated with plant extracts in form of traditional medicine. The antivenom activity of Paullinia pinnata Linn and Detarium microcarpum Guill and Perr, popular herbs used in the treatment of Echis ocellatus bites are of great interest and were investigated in vivo and in vitro against the venom (2mg/kg) of Echis carniatus. ...

ABSTRACT Garcinia kola Heckel (Guttiferae) seed, has found use in folkloric medicine of Southern Nigeria for the treatment of toothache and prevention of dental caries. The crude ethanolic extract, chromatographic fractions and isolated constituents of Garcinia kola seed against clinical strains of dental-caries-causing and related microorganisms is being evaluated. Antimicrobial evaluations were done by testing different concentrations of the crude extract, vacuum liquid chromatographic (VL...

Post-Junctional Alpha Adrenoceftors in the Anococcygeus Muscle and VAS Deferens: A Comparative Study in Normotensive and Spontaneously Hypertensive Rats

ABSTRACT The characteristics of the post-junctional -aarenoceptors in the isolated anococcygeus muscle and vas deferens were compared in spontaneously hypertensive rats (SHR) and normotensive rats (NCR). Responses to CK —adrenoceptor agonists were obtained in the absence and presence of cocaine and of antagonists, Noradrenaline I (NA) and phenylephrine (PE) produced concentration related contrac— tions of the preparations which were antagonised by phentolamine5 prazosin and yohimbine in b...

ANTIOXIDANT AND SELECTIVE CYTOTOXIC ACTIVITIES ON CANCER CELL LINES BY BIOACTIVATABLE COMPOUNDS IN EXTRACTS OF TERMITOMYCES SCHIMPERI (LYOPHYLLACEAE)

ABSTRACT BACKGROUND: Termitomyces schimperi (TS) is an edible mushroom that is known to possess certain therapeutic properties. Anecdotal report from La Cote d’Ivoire suggests that the mushroom is traditionally used in combination with kaolin, to manage a number of cancers. There is, however, a dearth of information on its antioxidant and anticancer properties with or without kaolin. AIMS: The aims of this study were to determine the antioxidant and cytotoxic potential of aqueous and ethano...

EFFECT OF 30-DAY ADMINISTRATION OF CELLGEVITY® ON SELECTED RAT LIVER CYP450 ENZYME ACTIVITY AND POSSIBLE INTERACTION WITH CARBAMAZEPINE

NEUROPHARMACOLOGICAL PROPERTIES OF ETHANOL EXTRACT OF Adenopus breviflorus (ROBERTY)FRUIT IN MICE

ABSTRACT Adenopus breviflorus is a perennial climber used locally as an anti-convulsant, sedative and pain-killer in West Africa. Several studies have reported gastrointestinal, reproductive and anti-microbial effects of extracts of Adenopus breviflorus, but there is dearth of information on its neurological effect. This study was therefore designed to investigate effect of Ethanol Extract of Adenopus breviflorus (EEAB) on central nervous system in mice. Three hundred gram of air-dried Adeno...
