These timeframes of comparison are shown on Fig. A, along with a representative instance of a international trend line match to the data. Table summarizes the median alterations in rBF trends for these time ranges in both strains. All round, the CH group showed a median (IQR) significant boost of (,) in rBF over the minute period (p.). Nevertheless, this increase was not continuous over time, considering the fact that half of it happened inside the initially minutes of monitoring, though the remaining change occurred over the following min. In contrast, tumor rBF didn’t transform significantly in the nude group, with a slight median enhance of (,) more than minutes. Accompanying these straindependent differences in tumor blood flow more than the min period were straindependent variations in mouse heart price. Nonetheless, neither tumor nor animal core temperature changed in either strain. More than minutes, CH heart price improved substantially (p .) from a median (IQR) of (,) beats per minute to (,) beats per minute.

Comparable nonsignificant adjustments have been located in core temperature, with values changing from. uC to. uC in CH and from. uC to. uC in nudes. Hence, there was no evidence of temperature contributing to the differential blood flow responses amongst nudes and CH, but straindependent change in heart rate is aligned with all the blood flow alter. Offered the increases in CH tumor blood flow, we speculated that tumors of CH animals might be a lot more oxygeted than these of nude animals. Since PDT is oxygendependent, this could facilitate the stronger PDTmediated vascular response identified in CH (see Fig. ). To study this possibility, phosphorescence lifetime measurements had been made use of to assess tumor oxygetion in CH and nude animals (Fig. ). Typical (SD) tumor oxygen tension in the 1st two minutes of anesthesia was Torr and Torr in nudes and CH, respectively, which changed to Torr in nudes and Torr in CH at the conclusion of min.
