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

ABSTRACTHippocampus functions have been reported to be affected by diabetes mellitus. Studies suggestthat within diabetic rats, garlic (A.sativum) improves different forms of memory that depend onthe hippocampus. However, the neuroprotective mechanisms of garlic (A.sativum) extractpossibly mediated by the Na+/K+ ATPase, Ca2+ATPase and glutamine synthetase (GS) in thehippocampus of type II diabetic Wistar rats has not been fully demonstrated. Therefore, the presentstudy 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...

PSG 201 Lesson Note: Ageing in Physiology

This is time related deterioration of the physiological function necessary for survival and fertility. Maximum life span- the maximum number of years a member of a specie has been known to survive. This maximum life span depends on the special Life expectancy: the age at half the population still survive, this is not the characteristics of specie or population. Why do they age? 1 The hereditary factor depending on what's going on the linage 2 loss of cellular mass and ability o...

ElectroPhysiology of the Heart

Cardiac muscle, like skeletal muscle, is a striated muscle and much of the mechanism of contraction is similar between the two muscle types. The electrophysiology of the two muscles differs: First ,the cardiac action potential is not initiated by neural activity. Instead, specialized cardiac muscle tissue in the heart itself initiates the action potential, which then spreads directly from muscle cell to muscle cell. Neural influences have only a modulatory effect on the heart rate. Second, th...

Respiratory System and Functional Anatomy

AbstractThe functional anatomy of the respiratory system and mechanism of respiration.The respiratory system consists of nostrils, nasopharynx, larynx, trachea, bronchi, bronchioles, alveoli duct and alveoli. The structures included from nostrils to terminal bronchioles will have 16 divisions, while the remaining structures show 7 divisions, giving a total of 23 divisions for the respiratory tract. The divisions are formed by the repeated branching of each segment of the tract.Structures like...

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 investiga...

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

AbstractThe first aim of this dissertation was to monitor both rat andhuman responses to short-term perturbations in energy balancebrought about through food energy restriction and refeeding,exercise training and the cessation of exercise training orsurgical lipectomy. The second aim of this dissertation wasto identify factors which might explain differences in foodenergy intake in weight-matched, weight-stable "large andsmall eaters". The final aim of this dissertation was toidentify...

Effect Of Ethanolic Extract Of Ocimum Gratissimum Leaves On Placental And Birth Weight And Early Postnatal Growth Of The Offspring Of Diabetic Pregnant Rats

ABSTRACTExtract of Ocimumgratissimum (OG) is popularly used to treat diabetes mellitusand its hypoglycaemic activity has been confirmed by in vivo studies. There ispaucity of data on the effect of this extract on placenta development and birthoutcome in diabetic pregnancy. This study was therefore aimed at investigatingthis.42 pregnant rats weighing 150-200g were used. They were divided into controland extract treated diabetic and non-diabetic groups with 6 rats in each subgroup.Extr...
