PURPOSE
To investigate the protective effect of citrulline (Cit) on the hearts of rats with sepsis.
METHODS
Wistar rats were divided into the normal, sham-operated, CLP, Cit, and CLP+Cit groups. Routine blood tests were performed, and the blood biochemical indexes were measured. Pathological changes in the cardiac tissues were observed. The levels of NO and iNOS in blood and SOD activity and MDA levels in the heart were measured.
RESULTS
Less inflammatory cell infiltration of the myocardial fibers and significantly decreased white blood cell count, absolute neutrophil count, neutrophil percentage, CK, HBDH, and NO (all <0.05) were detected in the CLP+Cit group compared with the CLP group. In addition, SOD activity and MDA levels in heart tissues were, respectively, higher and lower in the CLP+Cit group than in the CLP group (both <0.05).
CONCLUSIONS
Cit reduces pathological damage in the heart and enhances the heart's antioxidant capacity, thereby protecting cardiomyocytes.
目的
研究瓜氨酸（Cit）对脓毒症大鼠心脏的保护作用。
方法
将 Wistar 大鼠分为正常组、假手术组、CLP 组、Cit 组和 CLP+Cit 组。进行常规血液检查，并测量血液生化指标。观察心脏组织的病理变化。测量血液中 NO 和 iNOS 的水平以及心脏中 SOD 活性和 MDA 水平。
结果
与 CLP 组相比，CLP+Cit 组心肌纤维的炎性细胞浸润较少，白细胞计数、绝对中性粒细胞计数、中性粒细胞百分比、CK、HBDH 和 NO 均显著降低（均<0.05）。此外，CLP+Cit 组心脏组织中的 SOD 活性和 MDA 水平分别高于和低于 CLP 组（均<0.05）。
结论
Cit 减轻了心脏的病理损伤，增强了心脏的抗氧化能力，从而保护了心肌细胞。
