Fig. 3From: Antinociceptive activities of Artocarpus lacucha Buch-ham (Moraceae) and its isolated phenolic compound, catechin, in miceEffect of morphine, HEBA, (+)-catechin and naloxone treatments on latent time in tail immersion test. Panel a shows the effect of HEBA and naloxone pre-treatment on latency. Panel b shows the effect of (+)-catechin and naloxone pre-treatment on latent time. Data are presented as mean ± SEM (n = 5). * represents p < 0.001, compared to control group mice. a, b, c and d represent p < 0.001, compared to 50, 100 and 200 mg/Kg b.w. dose treatment group respectively. HEBA = hydro-methanolic extract of the bark of A. lacucha. NLX = naloxoneBack to article page
