Echocardiography Differentiates Lethally Irradiated Whole-Body From Partial-Body Exposed Rats

Modulator Effect of Turmeric on Oxidative Damage in Whole Body Gamma Irradiated rats

Because of its penetrating power and its ability to travel great distances, gamma rays are considered the primary hazard to the population during most radiological emergencies. So, there is a need to develop medical countermeasures to protect the first responders and remediation workers from biomedical effect of ionizing radiation. Turmeric has been reported to have many beneficial health effec...

Nucleolar behavior in regenerating liver of normal and whole-body-irradiated rats.

After partial removal of the liver in Wistar rats, the number of nucleoli in hepatocytes was found to be substantially reduced, especially in the periods preceding the outburst of mitoses. By delaying the appearance of mitotic waves by whole-body Xirradiation (1000 R) delivered prior to surgery, a more pronounced lowering of the nucleoli number was observed. Fol lowing each mitotic peak, develo...

Particle deposition in spontaneously hypertensive rats exposed via whole-body inhalation: measured and estimated dose.

A plethora of epidemiological studies have shown that exposure to elevated levels of ambient particulate matter (PM) can lead to adverse health outcomes, including cardiopulmonary-related mortality. Subsequent animal toxicological studies have attempted to mimic these cardiovascular and respiratory responses, in order to better understand underlying mechanisms. However, it is difficult to quant...

Ovarian Modifications in Mice Exposed to Whole-Body Irradiation

This experiment was designed to determine the involvement of varying levels of whole-body irradiation on ovarian follicular and corpora luteal development in mice. Previous research has indicated reduced counts of ovarian follicles and corpora lutea in mice flown in space. These differences may be the result of microgravity, increased exposure to radiation, or some combination of both. Fifty-si...
