The whole-brain dose was substantially decreased with proton therapy.
Of particular interest, the most recent description of three brain gliomas and one meningioma in interventional cardiologists all involved the left side, known to be more exposed than the right side, although no brain radiation dose was provided for any of these cases [ 40].
When using 2D-CRT, the entire brain dose, which was easier to determine and indirectly related to the maximum irradiation dose, seemed to correlate with the occurrence of radiation-induced brain injury [ 4].
Now that we were pretty sure that we weren't dying of deep brain thrombosis our next dose was a full pill, straight up.
However, the reduction of brain Aβ at this dose was accompanied by concomitant effects on endpoints related to Notch signaling in peripheral organs.
CPF given to pregnant rats on gestational days 17-20 or to neonatal rats on postnatal days 1-4, failed to elicit increases in thiobarbituric acid-reactive species (TBARS) in brain regions even when the dose was raised above the threshold for systemic toxicity and hepatic damage.
For inorganic Hg brain levels, the relationship to MeHg dose was not quite linear.
Doses were also calculated for different areas of the brain with the lowest average dose being for the back and front of the lower plane (mean 1.1 Gy, s.d. 0.37, range 0.71 4.30), whereas the highest dose was for the front of the upper plane (mean 1.8 Gy, s.d. 0.61, range 1.17 7.11) (Ron et al, 1988).
PQ in brain after oral dosing was previously demonstrated in rat and the concentration was higher after 10 doses compared with 1, supporting its accumulation (Widdowson et al. 1996).
Brain stem: the tolerated dose is 54 Gy, in volumes of appox. 1 cc the dose can be 60 Gy.
