PNS or Rb1 and Rd combination preserved retinal function in bright light-exposed mice. BALB/c mice were treated with vehicle, PNS at 200 mg/kg bw, or natural combination of Rb1 and Rd 30 min before bright light exposure. Retinal function was examined 10 d after bright light exposure. Scotopic ERGs were recorded and amplitudes of a-wave (A) and b-wave (B) were plotted. Data were expressed as mean ± S.E.M (n = 4–5 per group). *Compared to that from No light, p < 0.05; #PNS treatment was compared to that from Vehicle, p < 0.05; &Combination treatment of Rb1 and Rd was compared to that from Vehicle, p < 0.05.
