研究:食用草莓能预防胃病

 Researchers have discovered that strawberries can protect the stomach lining from alcohol, boosting hopes of improved treatment of stomach ulcers.

  The scientists gave ethanol to laboratory rats and found that the stomach mucous membrane of those which had eaten strawberry extract for the previous ten days suffered less damage.

  Researcher Sara Tulipani, of the University of Barcelona, said: "The positive effects of strawberries are not only linked to their antioxidant capacity, but also to the fact that they activate the antioxidant defences and enzymes of the body."

  Scientists say a diet rich in strawberries can help to prevent gastric illnesses and slow down the formation of stomach ulcers.

  The scientists said ulcer treatments needed protective medicines with antioxidant properties, and the compounds found in strawberries could be the answer.

  A team of Italian, Serbian and Spanish researchers were studying the mucous membrane, which contains special cells that produce acid and enzymes helping the body to break down. It also excretes mucus, which protects the lining from the acid.

  The study found that a diet rich in strawberries can have a beneficial effect when it comes to preventing gastric illnesses that are related to the generation of free radicals or other reactive oxygen species.

  Gastritis or inflammation of the stomach mucous membrane is related to alcohol consumption but can also be caused by viral infections or by nonsteroidal anti-inflammatory medication (such as aspirin) or medication used to treat against the Helicobacter pylori bacteria.

  Maurizio Battino, coordinator of the research group at the Marche Polytechnic University in Italy said: "In these cases, the consumption of strawberries during or after pathology could lessen stomach mucous membrane damage."

  The team found less ulcerations in the stomachs of those rats which had eaten strawberry extract (40mg/day per kilo of weight) for 10 days before being given alcohol.

  Battino emphasises: "This study was not conceived as a way of mitigating the effects of getting drunk but rather as a way of discovering molecules in the stomach membrane that protect against the damaging effects of differing agents."

  据英国《每日邮报》10月26日报道,研究人员发现,草莓能够保护胃粘膜免受酒精的刺激,有利于促进胃溃疡的治疗。

  科学家给实验室小白鼠服用了乙醇,发现那些在此前十天内曾吃过草莓提取物的小白鼠胃粘膜受到的损害比较小。

  巴塞罗那大学的研究员萨拉·图里帕尼说:“草莓的积极效应不只在于它的抗氧化能力,此外它还能激活抗氧化防御系统和人体内所含的酶。”

  科学家说,丰盛的草莓大餐可以帮助人们预防胃病,减缓胃溃疡的形成。

  科学家说胃溃疡的治疗需要保护性的具有抗氧化性能的药品,草莓中发现的化合物可能正是好的选择。

  由意大利、塞尔维亚和西班牙的研究人员组成的科研小组正在研究胃粘膜,它含有特殊的细胞,能够产生酸和酶,帮助人体分解食物中的蛋白质。它还能分泌出粘液,保护胃粘膜本身。

  研究发现多吃草莓对于预防胃病有着有利的影响,胃病与自由基或其他活性氧的生成相关。

  胃炎或是胃粘膜炎症与酒精的消耗量相关,但也有可能由病毒感染引起,使用非类固醇消炎药(比如阿司匹林)或者治疗幽门螺杆菌的药物也有可能引发炎症。

  来自意大利马尔凯理工大学的研究小组协调人员马基里奥·巴提诺说:“在这些案例中,病变时或病变后食用草莓都降低了胃粘膜的受损程度。”

  研究小组发现,在服用酒精之前的十天内一直吃草莓提取物(每公斤体重每天40毫克)的小白鼠,胃里的溃疡比较少。

  巴提诺强调:“这一研究并不能被看作是能够减轻醉酒影响的方式,而是有助于恢复保护胃粘膜免受不同损伤的分子的途径。”
