Relationship of ozone application and time in rats with hypoxic-ischemic brain injury.

Background: Despite the important advances in pregnancy and newborn follow-up, hypoxic-ischemic encephalopathy is still one of the prominent causes of newborn mortality and disability worldwide, and there is no sufficiently effective treatment for it yet. This study aimed to investigate whether the ozone injection, administered in a single-dose as a preconditioning agent before the hypoxia and in single and repeated doses on different days following the hypoxia, would affect the spatial memory performance of the rats in the Morris water maze test or on their apoptotic cell numbers.

Methods: The study consisted of 102 seven-day-old male Wistar baby rats randomly divided into five groups.

The efficacy of ozone therapy in neonatal rats with hypoxic ischemic brain injury.

Objectives: This study is aimed to determine the effect of ozone therapy in neonatal rats with experimentally induced hypoxic ischemic brain injury (HIBI).

Methods: The study included 7-d-old male Wistar rats that were randomized to the sham, control, ozone 1, and ozone 2 groups. All rats except those in the sham group were kept in a hypoxia chamber, and then the rats in the control group were given 0.

Is levetiracetam neuroprotective in neonatal rats with hypoxic ischemic brain injury?

Background: The aim of this study was to determine if levetiracetam (LEV) is neuroprotective in neonatal rats with hypoxic-ischemic brain injury (HIBI).

Methods: The study included 7-d-old male Wistar rats that were randomly divided into the LEV400, LEV800, control, and sham groups. All the rats, except those in the sham group, underwent ligation of the carotid artery and were then kept in a hypoxic chamber containing 8% oxygen for 2 h.

Fibroblast growth factor 2 improves cognitive function in neonatal rats with hypoxic ischaemic brain injury.

Objective: To determine the effect of fibroblast growth factor 2 on cognitive function in neonatal rats with hypoxic-ischaemic brain injury.

Methods: The randomised controlled study was conducted from January to June 2011 at Mersin University, School of Medicine, Experimental Animals Research Laboratory and Physiology Behaviour Laboratory, Mersin, Turkey. It included 7-d-old male rats that were randomised into four groups: fibroblast growth factor 2-20, fibroblast growth factor 2-40, control and sham.

The effects of fibroblast growth factor-2 and pluripotent astrocytic stem cells on cognitive function in a rat model of neonatal hypoxic-ischemic brain injury.

Objective: This study aimed to determine the effect of pluripotent astrocytic stem cells (PASCs) and fibroblast growth factor-2 (FGF-2) on cognitive function in neonatal rats with hypoxic-ischemic brain injury (HIBI).

Methods: The study was performed on 7-d-old rats that were randomly divided into four groups. All rats, except those in the sham group, were kept in a hypoxic chamber containing 8% oxygen for 2 h after the ligation of the right carotid artery.

Neuroprotective effect of levetiracetam on hypoxic ischemic brain injury in neonatal rats.

Purpose: Hypoxic-ischemic brain injury that occurs in the perinatal period is one of the leading causes of mental retardation, visual and auditory impairment, motor defects, epilepsy, cerebral palsy, and death in neonates. The severity of apoptosis that develops after ischemic hypoxia and reperfusion is an indication of brain injury. Thus, it may be possible to prevent or reduce injury with treatments that can be given before the reperfusion period following hypoxia and ischemia.

Determination of preferred walking speed on treadmill may lead to high oxygen cost on treadmill walking.

The energy consumption of walking relates to the intensity of physical effort and can be affected by the alterations in walking speed. Therefore, walking speed can be accepted as a crucial, determinant of energy consumption measurement for a walking test. We aimed to investigate the differences in preferred walking speed (PWS) determined both on overground and on a treadmill and, to measure walking energy expenditure and spatio-temporal parameters of gait on a treadmill at both, speeds.
