Normal, hepatectomied(partial) or CCI4 injected rats are infected intraperitoneally with human HBV-infected serum, and histopathological examination of major organs, and serologically HBV markers are checked. In the latter groups, the relationship between the regenerating hepatocytes and their infectivity toward HBV are investigated. 1) There are no specific histological changes in the liver which might suggest HBV infection of hepatocytes. 2) There is a tendency to increase basophilic mononuclear cells in the lymphoid organs. At the same time, HBcAb are positive in the rat's serum suggesting that these cells are immunologically oriented effector cells in the defense system. In the groups which received hepatic injury, the number of these cells are decreased. 3) HBcAb are positive in the groups of 5th day, 1 week, and 2 weeks' post-HBV injection. All groups with hepatic injury show trace in the 2 weeks post-HBV injection which corresponds to the concomitant decreased number of basophilic mononuclear cells in the lymphoid organs. 4) Above findings suggest that HBV will promote a proliferative reaction of the mononuclear cells in the lymphoid organs in the early stage of HBV infection. It appears that the infection stops there, and there would be no activation of the mechanism of antibody-dependent cellular cytotoxicity followed by injury of hepatocytes due to the attack of T-lymphocytes manifesting the clinical hepatitis.

Total 74 cases of colon cancer were examined in the Inje Medical College, Pusan Paik-hospital, which were collected from 1979 to the April 1986. The stromal histopathological findings are as followings; 1) The highest frequency of the good reactions of the four parameters of the stromal response (i.e., good general stromal reaction, peripheral tumor disintergration, and each inflammatory cell infiltration and fibrous proliferation alone) was found in Dukes class B1 and the least frequency in Dukes C1. The good general stromal response and the peripheral tumor disintegration are more closely related with the stage than the other two parameters. They are about 60% in class B1, 30% in class B2 and C2, and 20% in class C1. 2) The insistent poorest stromal response of the Dukes C1 in all parameters may be explained from the fact that the cancer cells of this particular stage are very aggressive biologically because the cancer cells are capable to invade the regional lymph nodes before the main tumor can infiltrate all through the layers of the wall. 3) Among the four types of the colon cancer, the better stromal reactions are observed in more than half of the cases of the well and moderately differentiated adenocarcinoma while this trend is completely opposite in the mucinous and poorly differentiated types. 4) The above findings indicate that how closely the stroma influences upon the progress of the colon cancer, or how closely it represents the status of the individual immunological force.

Gated myocardial SPECT and attenuation correction gave birth to new insights into the pathophysiology of ischemic myocardial perfusion and function in clinical routine practice. Gated myocardial Tc-99m-compound SPECT improved diagnostic accuracy of coronary artery disease and enabled us to observe motion and thickening of myocardial walls as well as myocardial perfusion at the same time. Quantitative and qualitative assessement of myocardial performance and perfusion let us to understand the myocardial physiology in ischemia and infarction. In every patient who underwent gated perfusion SPECT, we will find ejection fraction, left ventricular volumes and regional wall motion. There are hopes to use gated T1-201 SPECT for the same purpose and to use gated SPECT for evaluation of wall motion and thickening at stress or immediate post-stress. Attenuation correction could improve diagnostic accuracy mainly by increasing normalcy ratio or performance of non-expert physicians. Both gated methods and attenuation correction improved specificity of non-expert physicians in diagnosing patients with moderate pretest likelihood. New imaging techniques will fill the desire of cardiologists examine function and perfusion, and possibly metabolism in their clinical routine practice.

Two autopsy cases of polycystic disease of kidney were reported, both female,31 and 61 years of age: gravida 2,and 7 respectively. The incidence among autopsies was 0.3%.Both cases were accompanied with congenital polycysts in liver. The blood pressure of the cases was slightly or moderately elevated and hearts were moderately hpertropic. Renal function were not considerably impaired. Clinically the correct diagnosis were subarachnoidal hemorrhage(by rupture of aneurism) in 1st case and uremia after right nephrectomy in 2nd case. Etiology of the condition was discussed.
