Effects of melatonin administration on the testicular tissue inflammatory markers (a) NFk-β (b) TNF-α (c) IL-1β and apoptotic (d) GGT (e) Caspase-3 activities of pregabalin-exposed male Wistar rats. Data are expressed as mean ± standard deviation (n = 5). Bars carrying superscript ^a are statistically significant (p < 0.05) when compared to Ctrl; ^b are statistically significant (p < 0.05) when compared to Mel; ^c are statistically significant (p < 0.05) when compared to LD PG; ^d are statistically significant (p < 0.05) when compared to HD PG; ^e are statistically significant (p < 0.05) when compared to LD PG + Mel
