Effect Of Chronic Exposure To Petroleum Hydrocarbon Pollution On Some Biochemical Parameters Of Individuals Native To Ebocha, Niger Delta

ABSTRACT The impact of pollution due to gas flaring on individuals native to Ebocha in Niger Delta Area was investigated. One hundred and five apparently healthy individuals between 21-70years who consented for the study were screened, seventy five individuals from Ebocha and thirty from Nsukka-a control location with no history of petroleum hydrocarbon pollution. Standard analytical procedures were used in the determination of the concentration of ascorbic acid (AA) of the individu...

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 w...

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 Antioxidant Activities Of Dichloromethane Extracts Of Strychnos Henningsii G. And Ficus Sycomorus L.

Most of biochemical reactions in the body generates Reactive Oxygen Species (ROS), which are involved in the pathogenesis of oxidative stress-related disorders like diabetes, nephrotoxicity, cancer, cardiovascular disorders, inflammation and neurological disorders when they attack biochemical molecules like proteins, lipids and nucleic acid. Antioxidants are used to protect the cells or tissues against potential attack by ROS. Natural based antioxidants such as catalase, glutathione, su...

Prevalence Of Hypoglycemia In Newborn At Kenyatta National Hospital And The Response To Glucose Supplementation In Low Birth Weight

Hypoglycaemia in neonates is defined as blood glucose concentration below 1.1mmol/l for term neonates. A common abnormality in neonates, it is associated, with neurological damage and death when it occurs in the first few days of life.  This is more pronounced in rural set-ups without the knowledge, detection and management facilities. When promptly diagnosed and managed, its effects can be prevented or minimized.  Studies at Kenyatta National Hospital (KNH) show that 59.8% of...

In Vivo Anti-Inflammatory, Analgesic And Antipyretic Effects Of Dichloromethane Stem Bark Extract Of Acacia Mellifera In Mice And Rat Models

ABSTRACT Inflammation is a reaction to irritants that causes an injury to the body. Pain is a physical discomfort caused by injury or illness while pyrexia is an increase in body temperature above the normal range (36.5°C–37.5°C). Commonly used conventional drugs against inflammation, pain and pyrexia are effective but due to long term use, these drugs tend to be costly and are associated with adverse side effects. Traditional medicine has been used as an alternative and complem...

Antiproliferative Activities, Gene Expression Profiles And Toxicity Of Selected Medicinal Plants Against Cancerous And Normal Cells

Cancer is among the leading causes of morbidity and mortality worldwide and accounts for up to 28,000 deaths annually in Kenya. Globally, approximately 13% of all deaths annually are attributed to cancer. Surgery, radiation and chemotherapy are the current treatment techniques for cancer; however, these methods are expensive, have high failure rates and have been associated with detrimental side effects. Plants derived products could be good candidates in alleviating ...

Correlation Between High Density Lipoprotein Cholesterol And Kidney Function In Type 1 Diabetes Mellitus As A Predictor Of Diabetic Nephropathy In Human Subjects

ABSTRACT Diabetic nephropathy (DN) is a common microvascular complication occurring five years from onset of type 1 diabetes mellitus, leading to renal failure and death. It is characterized by albuminuria and a reduced glomerular filtration rate. Although much emphasis has been placed on screening for albuminuria and estimated glomerular filtration rate (eGFR) to predict or diagnose DN, less attention has been focused on the role of high density lipoprotein cholesterol (HDL-C) in risk...

In Vivo Hypoglycemic Activity And Safety Of Selected Medicinal Plants Used In The Management Of Diabetes Mellitus In Elgeiyo-Marakwet County, Kenya

ABSTRACT Diabetes Mellitus is a group of metabolic disorders sharing a common underlying feature of hyperglycemia with disturbances of carbohydrate, protein and fat metabolism. The disease may present with characteristic symptoms such as polydipsia, polyuria, polyphagia, blurring of vision, and weight loss and in its most severe forms, ketoacidosis or a non-ketotic hyperosmolar state may develop and lead to stupor, coma and, in absence of effective treatment, death. Hyperglycemia ma...

Biochemical Effects Of Sewage Pollution On The Benthic Organism Nerita Polita

ABSTRACTRapid urbanization has resulted into substantial increase in quantities of sewage, whichis traditionally discharged into the ocean, causing a number of environmental problemsincluding threats to oceanic lives as well as ground water contamination. So far, there islimited data in Kenya regarding the toxic effects of sewage on benthic organisms. Theaim of this study was to investigate the biogeochemical effects of sewage pollution onthe mollusc Nerita polita by determining its imp...
