The effect of oral administration of methanolic extract of Asteracantha longifolia (AL) seeds on acetaminophen (APAP)-induced acute liver damage in rats was investigated. The activities of marker enzymes (aspartate transaminase, alanine transaminase, alkaline phosphatase, lactate dehydrogenase, and gamma glutamyl transferase) and bilirubin level in serum and the levels of cholesterol, triglycerides, and free fatty acids in both serum and liver were found to be increased when rats were challenged with APAP. This was also associated with a significant reduction of serum and tissue phospholipids. Pretreatment with AL extract prior to the administration of APAP prevented these alterations as evidenced by liver histopathology. Results indicated that the extract could offer protection against APAP-induced liver damage, suggesting its hepatoprotective activity.
研究了口服长叶紫菀(AL)种子甲醇提取物对乙酰氨基酚(APAP)诱导的大鼠急性肝损伤的影响。当用APAP攻击大鼠时,发现血清中标记酶(天冬氨酸转氨酶、丙氨酸转氨酶、碱性磷酸酶、乳酸脱氢酶和γ-谷氨酰转移酶)的活性以及胆红素水平,以及血清和肝脏中胆固醇、甘油三酯和游离脂肪酸的水平均升高。这也与血清和组织磷脂的显著减少有关。在给予APAP之前用AL提取物进行预处理可防止这些改变,肝脏组织病理学证明了这一点。结果表明,该提取物可以提供针对APAP诱导的肝损伤的保护作用,表明其具有肝保护活性。
