Fig. 4From: Modulatory effect of Persea Americana oil against diethylnitrosamine-induced hepatotoxicity in rats: a proposed mechanismEffect of PA oil on liver tissue PARP-1 concentration in rats subjected to induced hepatotoxicity. The values are expressed as mean ± SD (n = 6). a = Significant to normal control group (P ≤ 0.05), b = Significant to DEN group (P ≤ 0.05) c = Significant to PA oil group (P ≤ 0.05)Back to article page
