The Effect of Hyperthermia on Radiation-Induced Carcinogenesis
Radiation Research, 1988Ten groups of mice were exposed to either a single (30 Gy) or multiple (six fractions of 6 Gy) X-ray doses to the leg. Eight of these groups had the irradiated leg made hyperthermic for 45 min immediately following the X irradiation to temperatures of 37 to 43 degrees C.

Laser-induced hyperthermia of ocular tumors
Applied Optics, 1989Experimental results for the optical distribution and temperature rise during laser irradiation of tumors are presented. The experimental conditions are chosen to simulate laser irradiation of ocular tumors. The tumor models are human retinoblastoma heterotransplanted in athymic mice, murine mammary carcinoma in C3H/HEJ mice, and B16 melanotic melanoma

Mechanism of Cocaine-Induced Hyperthermia in Humans
Annals of Internal Medicine, 2002The lethal effects of cocaine are unique among those of other illicit drugs because cocaine has the propensity to cause hyperthermia. The traditional view is that cocaine causes a hypermetabolic state with increased heat production. However, because cocaine-induced hyperthermia occurs primarily in hot weather, it is hypothesized that cocaine also ...

Opiate effects on isolation-induced hyperthermia
Pharmacology Biochemistry and Behavior, 1983The effect of brief separation from companions on temperature was studied in 24-day-old chickens. It was found that socially isolated animals became hyperthermic. Alternatively, control animals maintained in groups larger than 6 animals displayed no differences in temperature between the pre- and post-test.

Induced Hyperthermia in Brain Tissue in vivo
1994Concerning hypothermia treatment, knowledge of time-temperature and of temperature distributions within tumor volumes is essential in order to obtain the maximal therapeutic effect. New techniques are being developed to overcome these difficulties. Two different heat sources, a contact Nd:YAG laser system and an automatically controlled high-frequency ...

Hyperthermia-Induced Changes in Tumor Microcirculation
1988A biological rationale for treating malignant tumors with hyperthermia has been provided by a great number of studies in recent years. It became obvious that particularly nutritionally deprived, hypoxic and acidic tumor cells were very sensitive to heat (for a review see Dickson and Calderwood 1980; Overgaard and Bichel 1977; Overgaard 1981; Rhee et al.

The effect of induced hyperthermia on the immune system
2007Therapeutical hyperthermia has been considered for cancer therapy since William Coley observed tumour remission after induction of fever by bacterial toxins at the end of the 19th century. Because fever is associated with a variety of immunological reactions, it has been suspected, that therapeutical hyperthermia might also activate the immune system ...

Ultrasound-Induced Hyperthermia
1986Ultrasound offers special advantages in the heating of both superficial and deep-seated soft tissues. This is because of its flexibility and its ability to focus the beam onto the target region.

Externally Induced Hyperthermia
1988Hyperthermia continues to be the subject of numerous clinical trials and intensive multidisciplinary investigations in biology, physics and engineering laboratories. Progress has been steady but painstaking since investigators are continually challenged by the complex problems of determining how to combine hyperthermia with the already effective ...
