摘要: 目的:通过研究促红细胞生成素(Erythropoietin,EPO)对大鼠下颌下腺放射性损伤的防护作用,为临床进一步探索唾液腺放射性损伤的预防和保护提供实验基础。 方法:将30只Wistar大鼠平均分为3组,即对照组(模拟照射+注射盐水)、单放组(照射+注射盐水)、给药组(照射+注射药物)。大鼠头颈部一次性接受15 Gy大剂量放射线照射,给药组放射前30 min腹腔注射EPO,照射后隔日给药,持续2周,药物剂量为每次3000 IU/kg。放射后第90天测量大鼠唾液流率,测量完毕后取大鼠颌下腺制作石蜡切片,行HE染色、Masson染色,并通过免疫组织化学染色观察切片PCNA表达情况。结果:给药组大鼠唾液流率大于单放组,组织学观察给药组腺体损伤程度较单放组明显减轻,每高倍视野(×400)给药组PCNA阳性细胞数多于单放组。结论:EPO对唾液腺放射性损伤有较好的防护作用。

Abstract: Objective: To investigate the protection of erythropoietin (EPO) against the radiation-induced salivary glands injury in rats. Methods: Thirty rats were divided into 3 groups, which were the control group, radiation group (IR+saline), and treatment (IR+EPO) group. The rat's head and neck received a single dose of 15Gy. EPO treatment via intraperitoneal was started 30min before irradiation and then was repeated every 48h for the first 2 weeks at dose of 3000IU/Kg at the end of irradiation. The salivary flow rate was assessed after 90 days and then the submandibular was removed to make Paraffin for HE staining, Masson staining, and immunohistochemical staining to observe the expression of PCNA. Results: The IR+EPO group's salivary secretion was greater than that of IR+saline group and exhibited less injury of gland tissue than the IR+saline group. The control group showed a higher PCNA positive cell rate than the IR+saline group. Conclusion: EPO has a good protective effect against the radiation-induced salivary gland injury.
