Figure 1From: Involvement of neuronal IL-1β in acquired brain lesions in a rat model of neonatal encephalopathy Pup mortality during hypoxia and weight chart of the surviving pups. (A) Mortality (%) according to hypoxia duration in lipopolysaccaride (LPS) ± hypoxia-ischemia (HI)-exposed pups (20 to 150 pups per condition). χ 2 test: *** P ≤ 0.001. (B) Pup-weight follow up from post-natal day (P)12 to P20 (10 to 30 pups per condition and time point). Mean ± standard error of the mean; analysis of variance with Newman-Keuls post-test; * P ≤0.05, ** P ≤ 0.01, **** P ≤ 0.0001. h hour, g gram, NS Not significant.Back to article page
