Medical marijuana helps treat disorders such as chronic pain, nausea and seizures.
醫(yī)用大麻可以幫助患者緩解由于慢性疼痛、惡心或者突發(fā)急病等引起的身體不適。
Unfortunately, it can also...um...oh yeah, it can also impair memory and learning.
但不幸的是，它也能損傷記憶和認(rèn)知能力。
But a new study suggests we can prevent this side effect with easily available medication.
而現(xiàn)在一項(xiàng)新的研究表明我們可以用一些簡單容易獲得的藥物防止這些不良副作用。
The problem stems from the hippocampus, the brain region responsible for memory formation.
問題出在負(fù)責(zé)形成記憶的大腦區(qū)域海馬體身上。
So scientists exposed mice to THC, the psychoactive chemical in cannabis, and then looked at their brains.
所以科學(xué)家們給小鼠注射了THC，即四氫大麻酚，這是大麻中能夠毒害神經(jīng)的化學(xué)物質(zhì)，然后觀察實(shí)驗(yàn)小鼠的大腦變化。
They noticed that the hippocampi of the treated mice produced higher levels of an enzyme called COX-2.
科學(xué)家們注意到小鼠大腦內(nèi)的海馬體會產(chǎn)生更多被稱為COX-2的酶。
When the researchers administered drugs that reduced levels of COX-2, the memory problems disappeared as well.
當(dāng)研究人員們控制減少酶類物質(zhì)COX-2含量下降的藥物，影響記憶的副作用也消失了。
As did some neuron damage.
盡管確實(shí)出現(xiàn)一些神經(jīng)元損傷。
But protecting the brain against memory loss did not seem to stop the positive effects of marijuana.
但是保護(hù)大腦減少記憶損傷看上去也不能影響大麻的鎮(zhèn)靜效果。
The scientists used cannabis to treat a mouse model of Alzheimer's disease.
科學(xué)家們還對阿爾茨海默氏病的小鼠進(jìn)行了大麻刺激。
Whether or not they inhibited COX-2, pot appeared to be beneficial.
無論是否抑制了COX-2酶，這一罐大麻還是有效果的。
The work is in the journal Cell.
這項(xiàng)研究已經(jīng)在《細(xì)胞》雜志上發(fā)表。
Drugs that block COX-2 include anti-inflammatories, such as over-the-counter painkiller ibuprofen.
使用抑制COX-2酶的藥物包括如非處方藥鎮(zhèn)痛劑布洛芬等的抗炎藥。
But before you start self-medicating, you might want to wait for confirmation in people.
不過在你開始自我用藥緩解病痛之前，你還是等這種藥物在人群中的臨床試驗(yàn)有療效之后再使用為好。
