This study investigates the protective effect of calcium dobesilate (CaDob), an effective antioxidant and anti-inflammatory drug, on experimental liver ischemia-reperfusion injury (IRI).
Forty rats were divided into four groups. In Group 1, (sham), only hepatic pedicle was induced. In Group 2 (control), hepatic pedicle was reperfused for 90 min after being clamped for 60 min. No treatment was given in Group 1 and 2. In Group 3 (perioperative CaDob), 100 mg/kg CaDob was given 2 hours prior to the operation in which hepatic pedicle was reperfused for 90 min following a 60-min clamp. In Group 4 (preoperative CaDob), after 100 mg/kg/day CaDob was given for 10 days before the operation, hepatic pedicle was clamped for 60 min and reperfused for 90 minutes. At the end of these procedures, blood and liver tissue samples were collected for biochemical and histopathological assessment.
Liver function tests and tissue oxidative stress parameters were significantly lower in the preoperative and perioperative treatment groups than the control group. Furthermore, it was observed that histopathological injury in the control group significantly decreased in both perioperative and preoperative treatment groups.
Calcium dobesilate demonstrated a significant hepatoprotective effect in terms of its antioxidant and anti-inflammatory effects.
本研究探讨了多贝斯钙(CaDob),一种有效的抗氧化和抗炎药物,对实验性肝缺血再灌注损伤(IRI)的保护作用。
将40只大鼠分为四组。第1组(假手术组),仅游离肝蒂。第2组(对照组),肝蒂夹闭60分钟后再灌注90分钟。第1组和第2组不给予任何处理。第3组(围手术期CaDob组),在手术前2小时给予100mg/kg CaDob,然后肝蒂夹闭60分钟后再灌注90分钟。第4组(术前CaDob组),在手术前10天每天给予100mg/kg CaDob,然后肝蒂夹闭60分钟并再灌注90分钟。在这些操作结束时,采集血液和肝组织样本进行生化和组织病理学评估。
术前和围手术期治疗组的肝功能检查和组织氧化应激参数均显著低于对照组。此外,观察到围手术期和术前治疗组中对照组的组织病理学损伤均显著减轻。
多贝斯钙在抗氧化和抗炎方面表现出显著的肝脏保护作用。
