Abstract

Administration of Aacetylsalicylic acid in children with viral infections (influence B, chickenpox) can be related with development of Reye syndrome - severe encephalopathy and liver insufficiency with mortality in 50% of cases. During Reye syndrome most important is deficiency of carnitine and hepatocyte damage. Decreased amount of carnitine impairs the energy function of mitochondria and gluconeogenesis as well as production of urea. As a result develops toxic encephalopathy and liver insufficiency. The goal of the research was assessment of efficacy of L-Carnitine, Corvitin and their combination on functional state of liver in experimental model of Reye Syndrome in rats. The study was performed on mature white male Wistar rates with body mass 150-180g. 50 rats were randomly divided into 5 groups (10 rats in each group). The model of Reye syndrome was induced in accordance with A.Vengersky's method. Intraperitoneal administration of 4-pentenoic acid was performed once daily during seven days, the used dosage was 20mg/kg. The treatment of toxic hepatitis was carried with intraperitoneal administration of L-Carnitine 300mg/kg, Corvitine 100mg/kg and concurrent administration of these drugs. Monotherapy with Corvitin and L-Carnitin successfully improved liver function and equally decreased indicators of hepatocyte's cytolyses and increased levels of glucose and urea. The markers of cholestasis was slightly more improved during use of L-Carnitine. Simultaneous use of both drugs was effective in rats with Reye syndrome, indicators of liver damage normalized and herewith, no mortality outcome was observed. The most pronounced hepatoprotective effect of concurrent administration of L-Carnitine and Corvitin may be due to synergic action of these drugs and such regime can be recommended for correction of liver function during Reye syndrome.

摘要

在患有病毒感染(如流感、水痘)的儿童中使用乙酰水杨酸可能与瑞氏综合征的发生有关,瑞氏综合征是一种严重的脑病和肝功能不全,死亡率达50%。在瑞氏综合征中,最重要的是肉碱缺乏和肝细胞损伤。肉碱量减少会损害线粒体的能量功能、糖异生以及尿素的生成。结果会发展为中毒性脑病和肝功能不全。本研究的目的是评估左旋肉碱、复合维生素B及其组合对大鼠瑞氏综合征实验模型肝脏功能状态的疗效。研究选用体重150 - 180g的成年雄性Wistar大鼠。50只大鼠随机分为5组(每组10只)。按照A. 温格尔斯基的方法诱导建立瑞氏综合征模型。连续7天每天腹腔注射一次4 - 戊烯酸,使用剂量为20mg/kg。采用腹腔注射300mg/kg左旋肉碱、100mg/kg复合维生素B以及同时使用这两种药物来治疗中毒性肝炎。单独使用复合维生素B和左旋肉碱均成功改善了肝功能,同等程度地降低了肝细胞溶解指标,并提高了血糖和尿素水平。使用左旋肉碱期间胆汁淤积标志物的改善更为明显。两种药物同时使用对患有瑞氏综合征的大鼠有效,肝脏损伤指标恢复正常,且未观察到死亡情况。左旋肉碱和复合维生素B同时使用时最显著的肝脏保护作用可能归因于这两种药物的协同作用,这种给药方案可推荐用于瑞氏综合征期间肝功能的纠正。
