Hepatitis or how much has progressed, They developed a method can be determined only by blood test.

Hepatitis or how much is in progress, we have developed a lecturer Murakami Osakashiritsudai how you can determine only blood test. Not good for the liver tissue is removed by inserting a needle, and less burden on the patient. I want to receive the approval of the idea that advanced medical technology in three years.
Murakami and colleagues, noted that the ribonucleic acid of liver cells in the blood that is slightly (RNA), varies depending on the condition. By examining the RNA of 12 types in the blood of about 100 patients with the diagnosis has been confirmed, we made ​​sure that you can identify type B viral hepatitis, and type C, or determine the progress of the disease.
  Suspected hepatitis from liver function tests, such as blood, tissue is removed by inserting a needle into the stomach, and now, it is examining the severity. I take about 100 000 yen require hospitalization for about 3 nights. It is a new technique and can use the blood that was taken at the first inspection, it is that you need about 30 000 yen.
  Was able to correctly diagnose the severity, depending on the degree of progress that split 6-8. I said, "improve the accuracy further, want to reduce costs," Mr. Murakami said.
I hope you will continue to be developed one after another practical diagnostic methods painless cheap. Please proceed further research so that you can reduce the cost and increase practical accuracy.



肝炎がどれくらい進行しているか、血液検査だけで判断できる方法を大阪市立大の村上講師らが開発した。針を刺して肝臓組織を取り出さなくていいため、患者の負担も少なくなる。３年後に高度先進医療の認可を受けたい考えだ。
　村上さんらは、血液中にわずかにある肝臓細胞のリボ核酸（ＲＮＡ）が、病状によって変化することに注目。診断が確定している患者約１００人の血液で１２種類のＲＮＡを調べることで、肝炎ウイルスのＢ型、Ｃ型などを識別したり、病状の進み具合を判定したりできることを確かめた。
 　現在は、血液検査で肝機能などから肝炎を疑い、おなかに針を刺して組織を取り出し、重症度を調べている。３泊ほど入院が必要で１０万円ほどかかる。新しい手法だと、最初の検査で採った血液が使え、３万円ほどですむという。
 　重症度を正しく診断できたのは、進行度によって６～８割という。村上さんは「さらに精度を高め、コストも下げたい」と話す。
　安く痛くない診断方法が次々に開発され実用化していくといいですね。精度を高めてコストを下げて実用化できるよう更なる研究を進めてください。
