“…TTX (1 µM) (Yasumoto et al, 2004), ACPD (5-100 µM), and MCPG (500 µM) (Schwarz et al, 2000), AIDA (100 µM) (Kalda et al, 2000), PHCCC (30 µM (Thornton and Bornstein, 2002), EGLU (300 µM (Marti et al, 2001), PKI(14-22) (0.05-50 mM) (Sluka, 1997), and forskolin (1-30 µM (Akasu and Tokimasa, 1989) were all effective in each study. In many previous researches, AIDA (Aguirre et al, 2001;Meli et al, 2002;Zhou et al, 2001) and PHCCC (Maj et al, 2003;Mao and Wang, 2001a,b) have often used at concentrations lower than 100 or 30 µM, respectively.…”
