Fig. 9From: The organophosphate pesticide -OP- malathion inducing thyroidal disruptions and failures in the metamorphosis of the Senegalese sole, Solea senegalensis(a to d) PCNA immunolocalisation in different retinal layer from controls (a) and 1.56 (b), 3.12 (c) and 6.25 (d) malathion exposed organisms. e and f PCNA index calculated in the inner and outher nuclear layers respectively at 30 dph of malathion exposure. Note a significant increase of cell proliferation as malathion concentration increased in both inner (e) and outher (f) nuclear layers at 30 dph. Different letters indicate statistically significative differences between treatments. (* = P < 0.05; ** = P < 0.01; *** = P < 0.001). Scalebar represents 100 μmBack to article page
