Gelam honey exerts anti-inflammatory and antioxidant activities and is thought to have potent effects in reducing infections and healing wounds. The aim of this study was to investigate the effects of intravenously-injected Gelam honey in protecting organs from lethal doses of lipopolysaccharide (LPS). Six groups of rabbits (N = 6) were used in this study. Two groups acted as controls and received only saline and no LPS injections. For the test groups, 1 mL honey (500 mg/kg in saline) was intravenously injected into two groups (treated), while saline (1 mL) was injected into the other two groups (untreated); after 1 h, all four test groups were intravenously-injected with LPS (0.5 mg/kg). Eight hours after the LPS injection, blood and organs were collected from three groups (one from each treatment stream) and blood parameters were measured and biochemical tests, histopathology, and myeloperoxidase assessment were performed. For survival rate tests, rabbits from the remaining three groups were monitored over a 2-week period. Treatment with honey showed protective effects on organs through the improvement of organ blood parameters, reduced infiltration of neutrophils, and decreased myeloperoxidase activity. Honey-treated rabbits also showed reduced mortality after LPS injection compared with untreated rabbits. Honey may have a therapeutic effect in protecting organs during inflammatory diseases.
吉拉蜂蜜具有抗炎和抗氧化活性,被认为在减少感染和促进伤口愈合方面有显著效果。本研究的目的是调查静脉注射吉拉蜂蜜对器官免受致死剂量脂多糖(LPS)损伤的保护作用。本研究使用了六组兔子(每组6只)。两组作为对照组,仅接受生理盐水注射,不注射LPS。对于试验组,两组(治疗组)静脉注射1 mL蜂蜜(500 mg/kg溶于生理盐水中),而另外两组(未治疗组)注射生理盐水(1 mL);1小时后,所有四个试验组均静脉注射LPS(0.5 mg/kg)。LPS注射8小时后,从三组(每个处理流程各一组)采集血液和器官,测量血液参数并进行生化检测、组织病理学检查和髓过氧化物酶评估。对于存活率测试,对其余三组兔子进行了为期2周的监测。蜂蜜治疗通过改善器官血液参数、减少中性粒细胞浸润和降低髓过氧化物酶活性,对器官显示出保护作用。与未治疗的兔子相比,蜂蜜治疗的兔子在注射LPS后的死亡率也有所降低。蜂蜜在炎症性疾病期间对器官保护可能具有治疗作用。
