The present report deals with the behaviour of mast cells in mice in the course of Entamoeba histolytica infection by the strains. Mice weighing about l6 gm were used for three experimental groups; control, sham infection and experimental. The experimental group was infected with Entamoeba histolytica trophozoites directly into cecum by laparotomy. Strains isolated from three hepatic amoebic abscess cases were used. Mesenteric samples from the region of terminal ileum were fixed in methyl alcohol and stained with Pugh's solution. The ulcers in cecum were examined. Changes in number and structure of mesenteric mast cells and blood eosinophils were as follows. The number of mast cell in mesenteric tissues of the infected group increased from first day of the infection and persisted up to 34th day of the observation period. Degranulation and disruption of mast cells increased in the infected group compared with groups of the sham operation and the contro1, but showed no difference by the strains of Entamoeba histolytica. The blood eosinophilia was observed in the infected group and persisted until the observation period. Ulcers in cecum were found in all the infected groups. The results above indicate that mast cells are keenly related with the course of Entamoeba histolytica infection.

There are many kinds of treatments for hepatocellular carcinoma (HCC) such as surgical resection, liver transplantation, chemotherapy, interventional therapy [TACE, ethanol embolization, Immuno -chemoembolization, I131 -lipiodol embolization], thermal therapy, cryotherapy, and radiation therapy. Generally spontaneous remission is not common in HCC, however underlying mechanism of spontaneous remission is uncertain. We report a case of complete remission after one time TACE in ruptured HCC with review of literature about the effect of TACE and spontaneous remission. We conclude that arterial embolization is an effective alternative to surgery for hepatic hemostasis in patients with spontaneous rupture of hepatocellular carcinoma.

We experience a case of pseudopolycytemia in dilated cardiomyopathy in a 62 years old man with chronic alcoholism. The patient was successfully managed by stress reduction, stopping of smoking, abstaining from alcohol drinking, use of digoxin, small dose lasix, and phlebotomy. To our knowledge, this is the first case of pseudopolycytemia in dilated cardiomyopathy in Korea. We reported this case with a review of literatures.
