Table 2. Comparison between diastolic and systolic function of corpus cavernosum smooth muscle in rats in each group.

Group	Number (n)	Systolic function (%)	Diastolic function (%)
Normal	12	8.07 ± 2.52	40.51 ± 3.24
Blank	9	26.99 ± 2.82*	21.13 ± 2.11*
NC	10	27.99 ± 2.22*	20.96 ± 2.05*
TrkA	11	19.07 ± 2.21*#	27.93 ± 2.91*#
TrkA+NGF	10	15.74 ± 2.32*#&	35.57 ± 2.53*#&

Note: NC: negative control. ^*P < 0.05, compared with the normal group; ^#P < 0.05, compared with the blank group; ^&P < 0.05, compared with the TrkA group.
