Effect of Wooddust on Lung Function and Anthropometric Parameters of Carpenters and Non-Carpenters

ABSTRACT It is generally known that some types of dust impairs lung function. This study was designed with the aim to access if occupational exposure to wood dust from sawing and plaining of wood can impair the lung function of carpenters in Akim and Akai Efa timber market, Calabar. 40 subjects each for both test and controls were used for this study. The test group consisted of carpenters while the other 40 subjects used consist of 40 blue collar workers who had no obvious adverse occupation...

Semen Quality and Egg Hatchability in Local Turkey Fed Diets Containing Moringa Oleifera and Gongronema Latifolium Leaf Meal.

ABSTRACT The experiment was conducted to determine semen quality, fertility, egg hatchability and some biochemical parameters in Nigerian local turkey toms fed diets containing Moringa oleifera (MO), Gongronema latifolium (GL) leaf meals and their combinations. A total of 72 Nigerian local turkeys comprising of 54 males and 18 females were used for the study. The males were randomly divided into 9 treatment groups, each treatment was replicated 3 times with 2 toms per replicate. The treatment...

Assessment of Haematological Parameters in Anti-Retroviral Therapy (Art)-Naïve HIV Positive Children in Enugu, Nigeria.

ABSTRACT The Human immunodeficiency virus (HIV) infection is one of the most important emerging infections of this century. The human immunodeficiency virus (HIV) infection causes the Acquired Immune Deficiency Syndrome (AIDS) which is a systemic disorder characterized by deficiency in cellular immune responses. Haematological complications that accompanied HIV infections have been documented to be the second most common causes of morbidity and mortality in children. The haematological compli...

Prevalence of Congenital Colour Vision Deficiency in Nigerians Living in Ugep, Cross River State

ABSTRACT Colour vision deficiency and colour blindness are synonymous terms describing poor colour discrimination by the visual senses. Congenital colour vision defects are common, x-linked inherited, non-progressive and untreatable disorders. Elsewhere, screening for these disorders are an established practice so that those affected can be advised about occupational preclusions. However, population-based study on the broader impact of colour vision defects is limited. A descriptive crosssect...

Effects of Selected Artemisinin-Based Antimalarial Combination Therapies (Acts) On Indomethacin induced Gastric Ulcers in Wistar Rats

ABSTRACT The gastric mucosa defence mechanisms are altered counteractively by 4-aminoquinoline and artemesinin derivatives, yet these drug lines constitute artemisinin based antimalarial combination therapies (ACTs). The study was aimed at determining the gastric mucosa effects of two ACTs (artemether-lumefantrine and artesunate-amodiaquine). Specifically to determine the effect of the ACTs on induced ulcer index, antioxidative activity, lipid peroxidation and histopathologies induced by indo...

EFFECTS OF ACUTE RESTRAINT STRESS ON OXIDATIVE STRESS PARAMETERS IN ADULT MALE WISTAR RATS

The purpose of this study was to observe the least amount of acute restraint stress that was needed to produce significant changes in the oxidative stress parameters.Stress may be defined as a complex dynamic condition in which the homeostasis of an organism is disturbed or threatened. Several studies have reported on the effects of stress on the body and on the heightened susceptibility of the brain amongst other organs to the effects of stress. In this study we aim at checking how, and to w...

Electrolyte Physiology of Selected Serum Electrolytes and Nitric Oxide in Preeclamptics at The Korle-Bu Teaching Hospital

ABSTRACT Brief Background:  Preeclampsia is a multisystem disorder in pregnancy affecting 5-14% of all pregnancies worldwide. Preeclampsia is associated with an increased risk of cardiovascular diseases later in life of both the mother and the baby. It is common but its aetiology remains unknown. It is the most common, yet least understood disorder of pregnancy. Despite a steady reduction in maternal mortality from this disorder in more developed countries, the aetiology still remains uncle...

Neuroprotective Mechanisms Of Garlic (Allium Sativum) In Modulation Of Hippocampus Function In Model Of Type Ii Diabetic Wist Ar Ra Ts

ABSTRACT Hippocampus functions have been reported to be affected by diabetes mellitus. Studies suggest that within diabetic rats, garlic (A.sativum) improves different forms of memory that depend on the hippocampus. However, the neuroprotective mechanisms of garlic (A.sativum) extract possibly mediated by the Na+/K+ ATPase, Ca2+ATPase and glutamine synthetase (GS) in the hippocampus of type II diabetic Wistar rats has not been fully demonstrated. Therefore, the present study determined the e...

Risk Factors For Postoperative Acute Kidney Injury (Aki) Following Laparotomy For Abdominal Emergencies At The Korle- Bu Teaching Hospital

ABSTRACT Background: Postoperative acute kidney injury (AKI) is associated with increased morbidity, cost, prolonged hospital stay, and greater than 50% mortality rate in abdominal surgery. Among abdominal procedures, open surgical technique has the highest risk of postoperative AKI as compared to the laparoscopic approach. Postoperative AKI is a common condition in laparotomy patients. In patients with emergency abdominal conditions, laparotomy offers the only chance for cure. Various compl...

Investigation Of Renal Function Among Hypertensive Patients In Umuahia, South East Nigeria

ABSTRACT The prevalence of chronic kidney disease (CKD) is on the increase globally. Hypertension, a cause and consequence of CKD, is one of the leading risk factors that contribute to increased prevalence of CKD. Understanding the burden of CKD in hypertensive individuals will help promote preventive strategies and initiate measures to reduce the progression of CKD to end stage renal disease (ESRD). Estimation of glomerular filtration rate (GFR) is one of the reliable means of investigating...

Factors Affecting Energy Expenditure And The Efficiency Of Fuel Utilization: Feeding And Exercise Models

Abstract The first aim of this dissertation was to monitor both rat and human responses to short-term perturbations in energy balance brought about through food energy restriction and refeeding, exercise training and the cessation of exercise training or surgical lipectomy. The second aim of this dissertation was to identify factors which might explain differences in food energy intake in weight-matched, weight-stable "large and small eaters". The final aim of this dissertation was to identi...
