Lactate dehydrogenase (LDH) activity in mediums of keratinocytes: I. control; II. cultured with CBD (4uM) for 24h; III. cultured with CBD (4uM) for 48h; VI. irradiated with UVB [60 mJ/cm2]; V. irradiated with UVB [60 mJ/cm2] and cultured with CBD (4uM) for 24h after irradiation; VI. irradiated with UVB [60 mJ/cm2] and cultured with CBD for 24h befor irradiation and 24h after irradiation; VII. exposed to H2O2 [200μM]; VIII. exposed to H2O2 [200μM] and cultured with CBD (4uM) for 24h after exposer to H2O2; IX. exposed to H2O2 [200μM] and cultured with CBD (4uM) for 24h before and 24h after exposer to H2O2. Mean values ± SD of five independent experiments and statistically significant differences for p < 0.05 are presented: a - differences vs. group I/group IV/group VII; b - differences vs. group II/group V/group VIII; x - differences between group IV/group VII and group I.
