Ted Bateman tests bone loss therapy for cancer patients, astronauts

EarthSky

EarthSky spoke with biomedical engineer Ted Bateman of the University of North Carolina, Chapel Hill. With support from the National Space Biomedical Research Institute, he’s testing therapies to help protect the bones of astronauts in space from radiation.

今天節(jié)目組采訪了北卡羅來納大學(xué)教堂山分校的生物醫(yī)學(xué)工程師泰德?貝特曼。在國家空間生物醫(yī)學(xué)研究所的支持下，貝特曼著力試驗各種療法，保護(hù)宇航員的骨骼不受宇宙輻射的影響。

Ted Bateman: You’ve got astronauts, on average, losing one to two percent per month, which is very rapid, compared to causes for osteoporosis here on Earth.

泰德?貝特曼：在太空執(zhí)行任務(wù)的宇航員平均每個月會流失1%到2%的骨骼，與骨質(zhì)疏松癥患者相比，這種速度大得驚人。

In other words, said Bateman, astronauts in space can lose about as much bone in a month as an average senior citizen loses in a year here on Earth. Using micro computed tomography in studies on mice, Bateman found that space radiation rapidly attacks bone health.

貝特曼說，換言之，宇航員在太空中逗留一個月流失的骨量相當(dāng)于老年人一年流失的骨量。應(yīng)用X射線微型計算機(jī)斷層掃描技術(shù)進(jìn)行老鼠實驗，他發(fā)現(xiàn)空間輻射將對骨質(zhì)健康造成嚴(yán)重破壞。

Ted Bateman: From that, we’ve decided to initiate a couple of clinical trials to see if what we’re observing in mice is real in human cancer patients. And based on those preliminary data, we’re also seeing a very rapid decline in bone mass in cancer patients on the order of as fast as what astronauts experience from microgravity.

泰德?貝特曼：在此基礎(chǔ)上，我們決定做一些臨床試驗來檢驗鼠身上發(fā)生的現(xiàn)象是否會發(fā)生在癌癥患者身上。初步數(shù)據(jù)表明，試驗中癌癥患者的骨量也發(fā)生了急劇流失，速度類似于宇航員在微重力環(huán)境下的骨質(zhì)流失。

Bateman said he’s hopeful that his research on drug therapies for the bone degenerative disease osteoporosis will one day help both astronauts and cancer patients here on Earth.

貝特曼表示，他相信目前對于骨骼退化病骨質(zhì)疏松癥的藥物療法研究最終將造福于宇航員及癌癥患者。
