Abstract

Bisphenol A (BPA) is one of the most common worldwide chemicals involved in the industry of polycarbonate plastics, medical devices, and pharmaceuticals. Forty three-month-old albino rats were randomly classified into four groups. Group Ӏ received a daily corn oil dose (5 mL/kg/ body weight, BW) through a gastric tube for one month, Group ӀӀ received a daily dose of Curcumin (200 mg/kg body weight (B.W.) through a gastric tube for one month, Group ӀӀӀ received a daily dose of BPA (0.5 μg/kg B.W.) through a gastric tube for one month and Group ӀV received concomitant daily doses of Bisphenol A and Curcumin as the regimen described in groups ӀӀ and ӀӀӀ. The rats were sacrificed, and glandular portion of stomach was dissected and processed for light, immunohistochemical and ultrastructural study. BPA induced destructed gastric glands, dilated congested blood vessels, submucosal oedema, decreased PAS-positive reactivity, increased collagen fibres deposition, decrease in the positive BCL2 immunoexpression, increased positive PCNA immunoexpression, reduction in the gastric mucosal height and destructive changes in the enteroendocrine, chief and parietal cells. Curcumin coadministration provoked an obvious improvement in the gastric structure. BPA exposure has toxic effects on the glandular portion of the stomach in rats. Otherwise, Curcumin coadministration has exhibited protective impact on the architecture of the stomach.

摘要

双酚 A(BPA)是一种在聚碳酸酯塑料、医疗器械和制药行业中广泛应用的化学物质。43 月龄的白化大鼠被随机分为四组。第 I 组通过胃管每天给予玉米油剂量(5 毫升/千克/体重,BW),持续一个月;第 II 组通过胃管每天给予姜黄素剂量(200 毫克/千克体重(BW),持续一个月;第 III 组通过胃管每天给予双酚 A 剂量(0.5 微克/千克 BW),持续一个月;第 IV 组同时给予双酚 A 和姜黄素,剂量和方案与第 II 组和第 III 组相同。处死大鼠,解剖胃的腺体部分,进行光镜、免疫组织化学和超微结构研究。BPA 诱导胃腺破坏、扩张充血的血管、黏膜下水肿、PAS 阳性反应减弱、胶原纤维沉积增加、BCL2 免疫表达减少、PCNA 免疫表达增加、胃黏膜高度降低以及肠内分泌细胞、主细胞和壁细胞的破坏变化。姜黄素联合给药明显改善了胃的结构。BPA 暴露对大鼠胃的腺体部分有毒性作用。另一方面,姜黄素联合给药对胃的结构表现出保护作用。
