ABSTRACT Background: Studies to find the association between male infertility and mtDNA mutations have been carried out by many researchers but reports from these studies have been varied and contradictory at times. However studies of this nature are scarce in Ghana. The present study has therefore provided a baseline data on mtDNA mutations in relation to male infertility for further studies to be carried out in this area. Main Objective: The overall objective is to ascertain the common mtD...
ABSTRACT Medicinal plants continue to provide valuable therapeutic recipes, in orthodox and traditional healing systems, for the amelioration of diseases and disorders. The current study sought to evaluate the capacities of single herbal formulations (SHFs), double herbal formulations (DHFs), triple herbal formulations (this) and quadruple herbal formulation (QHF) of leaf extracts of Acanthus Montanus, Asystasia gangetica, Gongronema latifolium and Solanum melongena to ameliorate hyperglycem...
ABSTRACT This study investigated the effect of ethanol leaf extract of Mucuna utilis (EEMu) on lead acetate induced toxicity on Wistar albino rats. Acute toxicity analysis of the plant extract produced no lethality even at high doses of 3000 mg/kg body weight. Twenty albino rats weighing 115 – 235 g were divided into four (4) groups; the first groupof animals served as normal control and were not administered either lead acetate or EEMU. The second group was treated intraperitoneally with ...
ABSTRACT Plasmodium falciparum gametocytes are able to infect the mosquito even at levels below microscopic detection and are responsible for malaria transmission. Gametocytes are exposed to immune pressure from the host and as a result, the host is able to develop antibodies against these gametocytes. However, it has not been determined whether naturally acquired immune response against gametocytes have a direct correlation with the presence of sub-microscopic gametocytes in the peripheral ...
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 individuals (male...
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, superoxi...
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 all neonates ...
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 complementary d...
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 challenges being exp...
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 asses...
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 may be as ...
ABSTRACT Rapid urbanization has resulted into substantial increase in quantities of sewage, which is traditionally discharged into the ocean, causing a number of environmental problems including threats to oceanic lives as well as ground water contamination. So far, there is limited data in Kenya regarding the toxic effects of sewage on benthic organisms. The aim of this study was to investigate the biogeochemical effects of sewage pollution on the mollusc Nerita polita by determining its im...
ABSTRACT Tsetse flies (Glossina sp) are the vector of African trypanosomes, the causative agents of sleeping sickness in man and Nagana in cattle. The insect is strictly hematophagous, taking in significantly high quantities of water during bloodmeals that present a considerable osmotic challenge. This necessitates machinery for eliminating excess water. One potential candidate is a group of membrane channel proteins called aquaporins (AQPs) that are responsible for the movement of water acr...
ABSTRACT Antioxidants are chemical substances that inhibit oxidation (oxidation is a chemical reaction that can produce free radicals, leading to a chain reaction that may damage cells or other molecules) Free radicals are reactive oxygen species and reactive nitrogen species generated by our bodies naturally during normal metabolic functions. If free radicals overwhelm the body ability to regulate them, a condition known as oxidative stress ensues. Oxidative stress leads to the destruction o...
ABSTRACT Solanum incanum, Craterostigma pumilum and Euclea divinorum have been used for generations as folklore medicine for various ailments associated with pain and inflammation in humans in Kenya. However, there is scarcity of data on scientific studies done on their effectiveness, modes of action, toxicity and their phytochemical composition. The aims of this study was to evaluate the antinociceptive, anti-inflammatory and antipyretic potential of these plants crude extracts, to determine...
