(A) Ba2+ blocks the UVB-induced loss of K+ from HCLE cells. [K+]i does not differ from control in the presence of Ba2+ at 10–60 minutes after UVB exposure. Blocking K+ flux also prevents the increase in [Na+]i. (B) Ba2+ has a dose-dependent effect on the UVB-induced change in [K+]i 10 minutes after exposure to UVB. *significantly different from all other values within groups (p ≤ 0.05, n=4)
