A 77-year old man living in Kyunggi-Do, Korea was surgically treated at Seoul National University Hospital on April 1981, because of acute abdomen. At laparotomy, a 1.77m long adult Taenia saginata was found both in gallbladder and in common bile duct to cause acute gangrenous cholecystitis. The relevant literature were reviewed and possible mechanisms of the disease were discussed.

The term endometriosis refers to ectopic endometriume. It most often involves the pelvic organs, including ovaries, broad and round ligaments, fallopian tubes, cervix, vagina and the pouch of Douglas. We report a case of vesical endometriosis in a 4- year old female patient and review literature. Segmental resection of this mass with involved bladder resulted in cure and this lesion was confirmed histologically as endometriosis of the bladder.

Hantaan and related viruses have been implicated as causative agents for a diverse group of human diseases known collectively as "hemorrhagic fevers with renal syndrome" (HFRS). Outbred SD rats obtained within 24 hours after birth were inoculated by intracerebral (the first group) or intramuscular routes (the second group) with 10(9.5)/ml DL50 of Hantaan seed virus suspension in 0.02 ml and 0.1 ml, respectively. Brain, lung, liver, kidney and spleen were used for virus antigen detection by immunofluorecence and histopathologic examination. In the first group, immunofluorescent intensity of virus antigen was increased in all organs (especially brain) and persisted until time of death(day 9). The histopathologic changes were relatively mild in brain and spleen and unremarkable in liver, lung and kidney. In the second group, immunofluorescent intensity of virus antigen was markedly increased in brain until time of death(day 17), but decreased in other organs. The histopathologic findings, such as meningoencephalitis, interstitial pneumonitis with focal hemorrhage, and lymphoid hyperplasia of splenic white pulp were much prominent compared to the first group. However, those of liver and kidney were unremarkable. The chronology of virologic and pathologic findings in Hantaan-infected suckling rats suggests a possible immune-mediated mechanism in disease pathogenesis.

Experimental brain infarcts in rats were studied light and electron microscopically to investigate the factor(s) controlling contrast enhancement on CT scans of the infarcts. Brain infarction was induced by injection of fine autologous blood clots through the right internal carotid artery and the affected brain was processed for examination 1 day, 2 day, and 1, 2, 4, 6 and 8 weeks after the injection. The lesion of early, necro - degenerative stage(1 day to 1 week) showed structural disintegration of capillary endothelial cells with dissolution of tight junctions. The lesion of middle, regenerative stage(2 to 4 weeks) was characterized by proliferation of new capillaries, They had well - formed tight junctions and continuos basement membrane. The endothelial cells, however, had intraluminal villous projections and many pinocytotic vesicles, suggesting an increased permeability. The capillaries matured at late, reparative stage(8 weeks), appearing similar to those in normal brain tissue except that they were loosely surrounded by astrocytic foot processes. It was presumed that the ncreased permeability of new capillaries might play an important role for contrast enhancement observable clinically during the middle stage(2 to 4 weeks).
