Table 2.

pD₂ values and maximal responses (Emax) to KCl in aortic rings from 3-, 6-, and 10-month-old groups of both SAMR1 and SAMP8 mice

	SAMR1		SAMP8
	pD₂	Emax	pD₂	Emax
3 months	1.48 ± 0.01	620 ±15	1.48 ± 0.01	637 ± 21
6 months	1.44 ± 0.01	634 ± 25	1.45 ± 0.02	784 ± 38^,*
10 months	1.53 ± 0.02^,*	748 ± 24^,*	1.52 ± 0.01^,*	933 ± 23^,^,**

Values are means ± SEM. n = 10 animals per group

*P < 0.05 vs. SAMR1 group with same age, and **P < 0.05 vs. 3-month-old group of the same strain, and ***P < 0.05 vs. 6-month-old group of the same strain
