Bottom Line: The levels of liver transaminases were measured at day 1 and day 7 after APAP induction.The ALT and AST levels were significantly higher in the APAP groups at day 1 whereas the enzyme levels of all groups showed no significant difference at day 7.The extracts treatment significantly reduced the proinflammatory cytokine levels and significantly increased the 11β-HSD type 1 enzyme activity (p < 0.05).

ABSTRACT
Hepatic injury induces inflammatory process and cell necrosis. Plantago major is traditionally used for various diseases. This study aimed to determine the anti-inflammatory property of P. major leaf extracts on inflammatory reaction following acetaminophen (APAP) hepatotoxicity. Thirty male Sprague-Dawley rats were divided into 5 groups, namely, normal control (C), APAP, aqueous (APAP + AQ), methanol (APAP + MT), and ethanol (APAP + ET) extract treated groups. All APAP groups received oral APAP (2 g/kg) at day 0. Then, 1000 mg/kg dose of P. major extracts was given for six days. The levels of liver transaminases were measured at day 1 and day 7 after APAP induction. At day 7, the blood and liver tissue were collected to determine plasma cytokines and tissue 11β-HSD type 1 enzyme. The in vitro anti-inflammatory activities of methanol, ethanol, and aqueous extracts were 26.74 ± 1.6%, 21.69 ± 2.81%, and 12.23 ± 3.15%, respectively. The ALT and AST levels were significantly higher in the APAP groups at day 1 whereas the enzyme levels of all groups showed no significant difference at day 7. The extracts treatment significantly reduced the proinflammatory cytokine levels and significantly increased the 11β-HSD type 1 enzyme activity (p < 0.05). In conclusion, the P. major extracts attenuate the inflammatory reaction following APAP-induced liver injury.

Mentions: The mean levels of IL-1α, IL-1β, and TNF-α in all groups at day 7 were shown in Figure 1. The IL-1α level in the APAP group was significantly higher than that of the control group (p < 0.05) (Figure 1(a)). However, there was no significant difference in IL-1β and TNF-α between the control and the APAP group (Figures 1(b) and 1(c)). The level of IL-1α, IL-1β, and TNF-α in the APAP group was significantly higher compared to the treated groups (p < 0.05) which indicated that P. major treatment significantly reduced the proinflammatory cytokines. The mean levels of IL-6 and IL-10 in all groups were shown in Figure 2. The levels of IL-6 and IL-10 in all groups showed no significant difference (p > 0.05).
