Thermal damage threshold of brain tissue--histological study of heated normal monkey brains.
The thermal damage threshold of normal brain tissue was evaluated from immediate and delayed histological changes caused by hyperthermia treatment of normal monkey (Macaca fuscata) brains. A 2450 MHz microwave antenna and an antenna cooling system devised by our group were used for interstitial hyperthermia treatment. The antenna within the cooling system was inserted through a small craniectom...
متن کاملMicrostructural brain tissue damage in metabolic syndrome.
OBJECTIVE We investigated the association between metabolic syndrome risk factors and brain tissue integrity, as assessed by magnetic resonance imaging. RESEARCH DESIGN AND METHODS From the Leiden Longevity Study, which is a community-based study of long-lived subjects, their offspring, and partners thereof, 130 subjects (61 men; mean age 66 years) were included. A metabolic syndrome score wa...
متن کاملEffect of Ocimum basilicum hydro-alcoholic extract on oxidative damage of brain tissue following seizures induced by pentylenetetrazole in mice
Introduction: A relationship between epileptic seizures and brain tissue oxidative damage has been suggested. Ocimum basilicum (O. basilicum) has been shown to have beneficial effects including hypnotic and protective against tissue oxidative damage. The present study was designed to evaluate the effects of O. basilicum hydro-alcoholic extract on oxidative damage of brain tissue following s...
متن کاملEr:YAG laser ablation of tissue: effect of pulse duration and tissue type on thermal damage.
The thermal damage caused by 2.94-micron Er:YAG laser ablation of skin, cornea, aorta, and bone was quantified. The zone of residual thermal damage produced by normal-spiking-mode pulses (pulse duration approximately 200 microseconds) and Q-switched pulses (pulse duration approximately 90 ns) was compared. Normal-spiking-mode pulses typically leave 10-50 microns of collagen damage at the smooth...
متن کاملFlow thresholds of functional and morphological damage of brain tissue.
THE FUNCTIONAL STATE of the central nervous system is dependent on adequate delivery of the main substrates. For the supply of sufficient amounts of glucose and oxygen cerebral blood flow (CBF) has to be kept above a critical level. However, when perfusion drops below a certain threshold, in consequence, cerebral function becomes impaired. While the increase of blood flow above this threshold r...
