研究︰抗菌皂可能阻礙肌肉功能

A chemical found in soap, toothpaste, clothes and toys may cause muscle problems and should be used with caution, experts have said.
一種可在肥皂、牙膏、衣物與玩具發現的化學物質，恐引發肌肉問題，應謹慎使用，專家指出。

Researchers found an antibacterial agent, called triclosan, hampers muscle function in animals and fish and may have implications for human health.
研究人員發現稱為三氯沙的抗菌物會阻礙動物與魚類的肌肉功能，同時可能對人類健康有影響。

After testing the substance on mice and fish they found muscle strength was reduced, including heart function and fish were unable to swim as well. The findings were published online in the Proceedings of the National Academy of Sciences.
在對老鼠與魚進行該物質測試後，他們發現包括心臟功能的肌力衰減，而魚也無法游水。研究結果刊登在美國國家科學院學報網路版上。

Isaac Pessah, professor and chair of the Department of Molecular Biosciences in the UC Davis School of Veterinary Medicine and principal investigator of the study, said："Triclosan is found in virtually everyone’s home and is pervasive in the environment."
加州大學戴維斯分校獸醫學院分子生物科學系主任與教授、該研究計畫主持人佩沙說︰「幾乎可在每個人的家裡發現三氯沙，它在環境中十分普遍。」

In experiments the researchers exposed animals and fish to levels of triclosan equivalent to that which people may receive daily. The team also found that triclosan impairs heart and skeletal muscle contractility in living animals.
在實驗中，研究人員讓動物與魚接觸的三氯沙劑量相當於人們每日可能接受的量。研究團隊也發現三氯沙將損害活體動物的心臟與骨骼肌收縮力。

Nipavan Chiamvimonvat, professor of cardiovascular medicine at UC Davis and a study co-author, said："Although triclosan is not regulated as a drug, this compound acts like a potent cardiac depressant in our models."
加州大學戴維斯分校心血管醫學教授、該研究共同撰文者賈文蒙瓦特說︰「雖然三氯沙未受到藥物規範，然而在我們的研究模式中，該化合物的作用如同強效心臟抑制劑。」
