Aim: This study sought to evaluate the hepatoprotective potential of alkaloid extracts from V. doniana and F. thonningii leaves on alloxan-induced diabetic rats. Materials and Methods: Fresh leaves of V. doniana and F. thonningii were obtained from a local market Nkwagu in Abakaliki local government area of Ebonyi State. They were dried and pulverized to fine granules using manual grinder. Crude alkaloid was extracted using standard method. The acute oral toxicity of both plants was determine...

Ameliorative Potential of Bambara Nuts (Vigna subterranea (L.) Verdc) Extract against Acute Ethanol-Induced Oxidative Stress in Wistar Rats

Abstract The aim of this study was to determine the ameliorative potential of Bambara nuts extract against acute ethanol-induced oxidative stress in Wistar rats. Bambara nuts of the Songkhla 1 variety locally sourced in Obinze area of Owerri, Imo State, Nigeria were powdered using a coffee grinder and an extract obtained from a Soxhlet apparatus with methanol as solvent. Twenty-four adult male Wistar rats were acclimatized for seven days and were randomly divided into four groups of six rats ...

Aim: This study sought to investigate the effect of Bambara nut on hepatic biomarkers of Wistar rats.Methodology: The Songkhla 1 variety (red seed coat) of Bambara nuts were locally sourced in Obinze area of Owerri, Imo State, Nigeria. The seeds were peeled and ground to a fine powderusing a coffee grinder and extracted using soxhlet apparatus and methanol as the solvent. Twentyfour adult male Wistar rats were acclimatized for seven days during which they were fed ad libitum with standard fe...

Effect of Bambara Nut Consumption on Blood Glucose Level

Aim: This study sought to investigate the effect of Bambara nut consumption on blood glucose level and lipid profile of Wistar rats.Methodology: The Songkhla 1 variety (red seed coat) of Bambara nuts were locally sourced from   Obinze area of Owerri, Imo State, Nigeria. The seeds were peeled and ground to a fine powder using a coffee grinder and extracted using soxhlet apparatus and methanol as the solvent. Twenty four adult male Wistar rats were acclimatized for seven days during which the...

Qualitative Determination of Phytochemical Composition of Ethanolic Extract of Xylopia aethiopica Fruit

Aim: The aim of this study is to qualitatively determine the phytochemical compositions of ethanolic extract of Xylopia aethiopica fruit.Methodology: The fruits of Xylopia aethiopica were obtained from new market in Aba, Abia State and were identified and authenticated by Prof. (Mrs) Margaret Bassey of the Department of Botany and Ecological Studies, University of Uyo with the voucher number UU/PH/4e. The plant was deposited in the Herbarium of the Department of Pharmacognosy and Natural Medi...

Hepatotoxic effect of Xylopia aethiopica Fruit in Wistar Rats

Background: Xylopia aethiopica fruit has been reported to possess high medicinal value. Thus, people use it without any regard for its toxicity.Aim: This study is therefore aimed at investigating its toxicity on the liver 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 d...

In Vitro And In Vivo Anti-Plasmodial Activities Of Senna Occidentalis Roots Extracts Against Plasmodium Falciparum And Plasmodium Berghei

Plasmodium is a genus of parasitic protozoa, many of which cause malaria in their host. Five species namely; P. falciparum, P. malarae, P. ovale, P. vivax and P. knowlesi cause human malaria. Malaria due to P. falciparum is one of the most severe public health problems worldwide with an annual estimated 207 million clinical episodes and 627,000 deaths. The use of conventional antimalarial drugs as treatment for malaria is greatly hindered by drug resistance exhibited by the parasite. Conseque...

Pozzolana Cement Obtained By Calcining Raw Clays/Rice Husks Mixtures

The aim of the study was to investigate thermal activation of clays from selected regions of Mwea using rice husks (RH), as the only source of energy, to produce low cost pozzolanalime cement. The clays were sampled from Gikiiro and Ugweri regions and coded 2060 and 2062 respectively. The clays were calcined at temperatures between 500 and 800 oC for one and two hours. Further, the raw clays were blended with rice husks at different ratios and fired in a fixed bed kiln (FBK). The resultant as...

Variation Of Cyanide Levels In Processed Sweet Cassava (Manihot Esculenta Crantz) Leaves Grown In Busia And Kilifi Counties, Kenya

Cassava (Manihot esculenta Crantz) is the third most important food source around the world especially in sub - Sahara Africa. It is preferred due to its agronomical attribute such as ability to grow in poor soils and drought resistance. The consumption of its tubers and leaves has dual antagonistic contribution to mankind. On one hand, this perennial tropical crop contains carbohydrates, vitamins, calcium and iron which are of nutritional benefit while on the other hand, they contain cyanoge...

Iron Ore Mineral Deposits Exploration By Ground Magnetics In Kindani Area, Meru County, Kenya

Recent geophysical surveys have reported presence of iron ore deposits within Meru County. It has been speculated that there could be more deposits within the region. Ground magnetic surveying was used to detect magnetic rocks within host formations in Kindani area of Maua. A fluxgate magnetometer was used to measure the vertical component of the Earth’s magnetic field in some 98 stations, covering an area of about 25 km2. Diurnal and geomagnetic corrections were then done on the data. A co...

Heavy Metals Distribution in Soil and Plants in the Vicinity of a Municipal Dumpsite Along NPA Expressway, Warri

ABSTRACT This Research examines the heavy metal distribution of a dumpsite in Uvwie Local Government Area along Warri Port Express-Way of Delta State Nigeria. A total of eight (8) soil samples and (2)-plant sample were collected from the study area and also control site using a systematic sampling technique. Samples were taken to the lab and analyzed to determine the physicochemical parameters and heavy metal content. The dumpsite is contaminated with heavy metals such as iron (ranging from...

Infections With Intestinal Protozoa And Geohelminths And The Risk Factors Among Secondary School Students In Maara Sub-County, Tharaka-Nithi County, Kenya

Intestinal parasitic infections caused mainly by protozoa and helminths are most prevalent in tropical and subtropical regions of the world where adequate water and proper sanitation are lacking. Helminthiasis has been listed among the three most prevalent diseases in Tharaka-Nithi County. The residents are mainly small scale nonmechanized farmers hence there is frequent contact with the soil. Chronic parasitic infection among students negatively affects their health, nutrition, cognitive dev...

An Assessment Of Ph, Toxic And Essential Plant Elements In Greywater From Selected Households In Kenyatta University, Kenya

Kenya is experiencing acute water shortage resulting to water rationing, conflict among water users, increased water prices among others. Therefore, there is need for water conservation. One of the water conservation methods available today is greywater reuse. Greywater is domestic wastewater generated from kitchens, bathrooms, and laundry activities. According to World Health Organization (WHO) each household in capital cities of most countries produces an average greywater flow of 356 litre...
