Relative lactate dehydrogenase (LDH) activity measured in primary macrophages culture supernatant after incubation with methamphetamine (meth). Macrophages were exposed to phosphate-buffered saline (control [ctrl]), meth (10, 25, 50, or 100 μmol/L), or chloroquine (clq) (20 μmol/L) for 24 h. Bars represent the means of the results for 3 measurements, and error bars denote standard errors. Analysis of variance was used to calculate significance and adjusted by use of the Bonferroni correction.
