摘  要:21例代偿期肝硬化(LCC),18例失代偿期肝硬化(LCD)、12例慢性重症肝炎(CSH),20例肝内胆汁淤积(IHC)和18例肝外胆汁淤积(EHC)患者于胰高糖素负荷试验前、后分别测定了血浆cAMP值。结果显示负荷前各组值差异无显著性意义(P>0.05)。负荷后各组值均较负荷前有不同程度升高,其中,以EHC患者升高最明显(1212.50±281.12pmol/L),其次为IHC(954.15±238.45)患者。相反,LC、CSH患者血浆cAMP反应性,正常人为低下(P<0.01),尤以CSH患者最明显(172.33±75.16)。其中血浆cAMP值低于100pmol/L的5例患者均于住院期间死亡。以上结果表明,采用glucagon负荷试验有助于黄疸性质的鉴别,并可作为估价肝脏储备功能较理想的指标,且对肝硬化患者预后判断有实用价值。lucagon loading Test was carried out in 24 healthy persons as control,21 cases of compensated liver cirrhosis (LCC),18 cases of decompensated liver cirrhosis (LCD),12 cases of chronic erious hepatitis (CSH),20 cases of intrahepatic cholestasis (IHC) and 18 cases of extrahepatic cholestasis (EHC).the plasma cAMP level was measured by RIA method.The results showed that before glucagon loading test,there was no difference among the cAMP level of all groups (P>0.05).After glucagon loading test,the plasma cAMP level was increased in all groups,especially in cases with EHC,the plasma cAMP level was significant increased (1212.50±201.12pmol/L),while that in IHC group,the cAMP level was 954.18±238.45pmol/L,on the other hand,the plasma cAMP values of cases with liver cirrhosis and CSH were lower (P<0.01),especially in cases with CSH was the lowest level (172.33±75.16pmol/L).The plasma cAMP level less than 100 pmol/L died in five cases with CSH.Condusion:the plasma cAMP level can be used as an index for the differential diagnosis of jaundice.It can also help to estimate the reserved hepatic function as well as prognosis of liver cirrhosis.
