Cultures were exposed to drugs for 24 hr. mGlu receptor ligands were applied 10 min before PHCCC. Values are means ± SEM of six to nine determinations from two to three independent experiments. p < 0.05 (1-way ANOVA plus Fisher's PLSD) versus the respective values in the absence of PHCCC (None) (a) or the respective control values (b). ND, Not determined.
