At the end of the experiments, the rats were anaesthetized [http://www.selleckchem.com/products/MLN8237.html Alisertib datasheet] with urethane (1.25 g kg?1?i.p.), and 100 nl of filtered 1% Evan's Blue dye was injected into the brain as a marker for the injection site. The chest was surgically opened, the descending aorta occluded, the right atrium severed and the brain perfused with 10% formalin through the left ventricle. The brains were postfixed for 48 h at 4��C, and 40 ��m sections were cut using a cryostat (CM1900; Leica, Wetzlar, Germany). Brain sections were stained with propylene glycol. The placement of the injection needles was verified in serial sections, using the rat brain atlas of Paxinos & Watson (1986) as reference. Data were expressed as means �� SEM. Baseline MAP and HR values were compared using Student's paired t test (before treatment versus after treatment). For all time courses of cardiovascular responses, the data were expressed as means �� SEM of changes in MAP (��MAP) or HR (��HR). The data points were sampled at 25 s intervals. Points sampled during the 75 s before PVN microinjection were used as control baseline values. The MAP and HR changes were analysed using two-way ANOVA, with treatment as the main independent factor and time as the repeated measurement. When an interaction between factors was observed, groups were compared at specific times using the Bonferroni post hoc test. A value of P [http://www.selleckchem.com/products/gsk-j4-hcl.html GSK J4 purchase] showing unilateral sites of microinjection into the PVN of all animals used and a photomicrograph of a coronal [http://en.wikipedia.org/wiki/ErbB ErbB] brain section depicting bilateral microinjection sites in the PVN of one representative animal are presented in Fig. 1. Microinjection of ACSF into the PVN did not affect either baseline MAP (before ACSF, 90 �� 2 mmHg; afterwards, 92 �� 2 mmHg; t= 1.5, P > 0.05, n= 6) or HR (before ACSF, 366 �� 13 beats min?1; afterwards, 356 �� 7 beats min?1; t= 1.7, P > 0.05, n= 6). Injections of 0.06, 0.12 or 1.2 nmol (100 nl)?1 methyl ATP into the PVN caused dose-related pressor and tachycardiac responses (Fig. 2A). Non-linear regression analysis pointed to a significant correlation between dose and the hypertensive (r2= 0.85, P
