Only the rats that exhibited a mean rotation toward the healthy side at least 6.0 full body turns per min were considered as disease onset.
23 The ZDF rats were developed by selective inbreeding of Zucker fatty (ZF) rats that exhibited high blood glucose.
The proportions of rats that exhibited the PAHBs on different postnatal days are graphically presented in Figure 1.
Four rats from the sham group and four rats that exhibited the behavioural signs of tinnitus were selected from each exposed-clean cage and exposed-dirty cage group.
Further, there was no sex difference in aged rats that exhibited an overall spatial learning impairment, however aged males now had smaller cholinergic neurons whereas no change was observed in females.
One microlitre of cell suspension was injected into the head of striatum in intrastriatal 6-hydroxydopamine lesioned rats that exhibited unilateral motor deficits, as determined by amphetamine-induced rotational behaviour and impaired forelimb use in the cylinder test.
We ranked and selected rats to form three groups based on the number of premature responses on the 5-CSRTT: HI rats that responded prematurely on more than 50% of trials (mean 76.6, n = 6); LI rats that were the lowest ranked animals (mean 24.7, n = 6); and MI rats that exhibited an intermediate level of impulsivity (mean 44.9, n = 6).
For instance, in the present study VEGFR-2 blockade marginally, but non-significantly, attenuated hyperfiltration in diabetic Ren-2 rats that exhibited increased renal eNOS-NO activity, whereas we previously found GFR to be markedly reduced with vandetanib in normoglycemic Ren-2 rats [ 4].
Thus, the decreased expression of the Shh transcript after METH challenges in the two saline-pretreated groups, which show decreased dopaminergic markers, in contrast to normal Shh mRNA levels in the METH-preconditioned rats that exhibit normal levels of DA and TH protein, suggest that SHH may play a partial role in maintaining DA homeostasis in the striatum of METH pretreated rats.
Specifically, female rats that exhibit low freezing levels during fear conditioning could be erroneously described as expressing low fear and/or poor learning, when in fact they have engaged darting responses.
