A Study on the Intrapulmonary Shunt Measured by (99m) Tc-MAA Perfusion Lung Scan / 영남의대학술지

Intrapulmonary shunt measured by (99m)Tc-MAA perfusion lung scan. The study was included 76 patients. Significant amount of intrapulmonary shunt was observed in the pulmonary disease patients and liver disease patients. The shunt amount was correlated well with PaO2 and AaDO2 level. Further study is needed to search the various factors affecting the amount of intrapulmonary shunt.

A Clinical Study of HBV Markers in Various Liver Diseases Carriers and Controls / 영남의대학술지

Serum HBsAg, AntiHBs, HBeAg, AntiHBe, and AntiHBc were detected by radioimmunoassay in 39 patients with acute viral hepatitis, 79 patients with chronic hepatitis, 30 patients with liver cirrhosis, 16 patients with primary hepatocellular carcinoma, 14 patients of HBsAg carriers and 129 cases of controls: 78 cases of normal level of SGOT, SGPT, and 51 cases of elevated level of SGOT, SGPT. Following results were obtained: 1. HBsAg was detected in 66.7% of acute viral hepatitis, 63.3% of chronic hepatitis, 36.7% of liver cirrhosis, 81.3% of primary hepatocellular carcinoma and 27.1% of controls. 2. AntiHBs was positive in 0% of acute viral hepatitis, 21.5% of chronic hepatitis, 36.7% of liver cirrhosis, 31.3% of primary hepatocellular carcinoma, 0% of carrier and 44.2% of controls. 3. HBeAg was detected in 45.6% of chronic hepatitis, 23.3% of liver cirrhosis and 31.3% of primary hepatocellular carcinoma. 4. Among chronic liver diseases, antiHBe was positive in 56.3% of primary hepatocellular carcinoma, 23.3% of liver cirrhosis and 20.3% of chronic hepatitis. 5. AntiHBc was detected in most of all examinees and the significance of presence of AntiHBc does not seem to represent liver disease itself but the evidence of infection of HBV. 6. Among 14 HBV carriers, 6 cases presented with abnormal SGOT, SGPT. 7. All HBV markers were negative in 5.1% of acute viral hepatitis, 5.1% of chronic hepatitis and 14.7% of controls: 17.6% of subjects with abnormal SGOT, SGPT and 12.8% of subjects with normal SGOT, SGPT. 8. Beside of HBV, other causes, such as non A, non B virus, Delta-agent, other viruses or related factors should be excluded among the patients with evidence of HBV infection associated with elevation of SGOT & SGPT.
