| Research Abstract |
We have achieved the results by the clinical and basic studies.【Study 1】We developed a rat model of acute liver failure after 2/3 partial hepatectomy (PH) for non-alcoholic steatohepatitis (NASH)-related cirrhosis. The mechanism by which HT improved the survival of the model rats was examined in short- and long-term investigations. Overall survival was significantly longer in the HT group than the non-HT group (7-day survival rates: 46.7% and 7.7%, respectively). Preoperative HT might improve the survival of rats with NASH-related cirrhosis after PH by preventing the host hepatocytes from accelerating their growth and falling into apoptosis. 【Study 2】We developed software to calculate the pixels of interest in the area between the hepatic and heart curves (ABC) of 99mTc-galactocyl human serum albumin (GSA) scintigraphy. The area under the receiver operating characteristic curve (AUC) was calculated for evaluation of Child-Pugh score grade B (Child B), pathological chronic hepatitis (CH), and liver cirrhosis (LC). We developed a novel liver functional indicator, the ABC, to count radioactivity in sequence.
