Fig. 2.
NGF levels (pg/mg wet weight) in stellate ganglion (SG) and dorsal root ganglion (DRG) tissue of control rats, and rats with chronic heart failure (HF) at different time course. *P < 0.05, versus control. There was no significant difference in NGF levels at different time course after ligation of the coronary artery. 3–5 control rats and 6–8 HF rats were used in each group
