We report a case of a 41-year-old female patient who suffered from the acute abdominal pain for several hours after eating raw sea-fishes. After the fibergastroscopy and the abdominal C-T scan, the clinicians found a gastric submucosal mass and performed the explolaparotomy to get an wedge of stomach. Sections revealed a larva surrounded by phlegmonous inflammation with intense eosinophilic infiltration in the widened gastic submucosa. The larva presented the characteristics of the Anisakis: two lateral chords with renette cell, thich smooth cuticle and well developed musculature.

Kupffer cells are tissue macrophages (histiocytes) fixed in hepatie sinusoids. Since malignant hepatocytes are the only tumor parencymal cells of the hepatocellular carcinoma, theoretically there are no Kupffer cells within the hepatocellular carcinoma. To clarify whether it is true or not, 12 cases of hepatocellular carcinoma of the trabecular type with some extents of the non-neoplastic surrounding liver were subjected to immunoperoxidase staining for lysozyme and S-100 protein and the results are as follows. 1) Kupffer cells were stained positively by the immunoperoxidase staining for lysozyme but not for S-100 protein, indicating that they are monocyte derived macrophages. 2) Kupffer cells were also present within the hepatocellular carcinoma, but were 2-7 times fewer within the hepatocellular carcinoma than in the non-neoplastic areas (p<0.05). 3) The non-neoplastic hepatic tissue of patients with serum HBsAg shows a tendency to have more kupffer cells than those without HBsAg.

To evaluate the frequency of EM A and Ki-I antigen expression in the large cell lymphoma and to define the histologic characteristics of Ki-1 positive anaplastic large cell lymphoma, 40 cases of malignant lymphoma, diffuse large cell type were immunostained by Ki-I and EMA monoclonal antibodies. Eight cases of large cell lymphomas expressed EMA, among which 4 cases were positive for Ki-I antibody as well. The positive rate for EMA was much higher in T cell lymphomas than in B cell lymphomas. Among 4 cases of Ki-I positive lymphomas, 2 cases showing membrane staining of Ki-1 with prototypic histologic feature of anaplastic large cell lymphoma were classified as Ki-1 positive anaplastic large cell lymphoma(ALCL). Ki-I positive ALCL were T-cell in one and non-T, non-B cell type in the other, respectively. The remaining 2 cases of Ki-1 positive lymphomas showing cytoplasmic staining were classified as both B-cell centroblastic/centrocytic lymphoma and T-cell pleomorphic large cell lymphoma.

The controversy over the hepatotoxic effect of the halogenated anesthetic agents, particullary halothane, is still not resolved despite many years of continued study. Enflurane(synthesized by R. Terrell in 1963) reduces the potential for hepatotoxic effects as compared to some fluorinated agents because of a relatively low level of biotransfomation, but liver injury following enflurane anesthesia has been reported, and was attributed to hepatotoxic agents, upper abdominal surgery, blood transfusion, shock, hyperpyrexia and sepsis. This study was undertaken to evaluate the effect of enflurane on liver function by comparing the preoperative and the 48 hour postoperative liver function tests in 25 cases of enflurane and also in 20 cases of balanced anesthesia. Other factors considered were the influences of the duration of anesthesia, the type of surgery, and the use of blood transfusion. The results were as follows: 1) SGOP and SGPT levels were significantly increased in enflurane group; but SGOT were increased above the normal range, on the other hand SGPT were remained within normal limits. 2) SGOT and SGPT levels were increased significantly in the balanced anesthetic group: but SGOT were increased above the normal range, on the other hand SGPT were remained within normal limits. 3) SGOT and SGPT levels were significantly increased following prolonged anesthesia of 3 hours. 4) SGOT and SGPT levels were significantly increased after gastric surgery. 5) SGOT and SGPT levels were significantly increased after blood transfusion. 6) But the other values of the liver function test, such as alkaline phosphatase, total bilirubin and total protein were not significantly increased and remained within normal limits. Although minute changes in liver function were occured following enflurane anesthesia, it is suggested that the changes in liver function were more influenced by the duration of anesthesia, the type of surgery and the administration of blood rather than the kinds of anesthetic agents.

Laparoscopic resection of appendiceal mucoceles has recently been described, but the safety and efficacy are controversial. We present two cases of laparoscopic mucocelectomies involving 14 and 15 cm cystic masses originating from the appendix. The laparoscopic mucocelectomies were performed using four ports. From the beginning of the procedure, a laparoscopic bag was used to safely contain the mucocele, prevent rupture of the mucocele, and retract the mucocele. An endoscopic stapling device was used to transect the base of the cecum. Minimal handling was achieved by gravity and with the use of laparoscopic instruments. Laparoscopic appendectomies are widely performed for acute appendicitis, but laparoscopic resection is not routinely performed for an appendiceal mucocele because of the risk of perforation and subsequent pseudomyxoma peritonei. We report two cases of laparoscopic appendiceal mucocelectomies, which were performed safely with laparoscopic instruments and minimal manipulation.

The authors have experienced a case of incompatible blocd transfusion during general anesthesia, which was mostly due to technical error, lack of knowledgeoble handling and universal doncr "0" type blood.

This study was undertaken to elucidate the short-term effect of iron on the hyperplastic lesions of experimental hepatocarcinogenesis. The Solt-Farber's resistant hepatocyte model was chosen for the experiment, and Sprague-Dawley rats wee divided into six groups: normal control, iron-rich diet administration with or without hydroxyquinoline. The iron content, microscopic changes, bromodeoxyuridine(BrdU) labelling index and the DNA polidy were studied. In the carcinogen administered group, oval cell proliferation and consecutive hyperplastic lesions of hepatocyte developed regardless of iron administration. The hepatic iron content was increased rimarkably by iron administration, but gradually decreased as the hyperplastic lesions developed in carcinogen administered groups. Although the administration of iron without carcinogen induced hepatic accumulation of stainable iron, the hyperplastic lesions appeared to be lack of it. BrdU labelling indices of the oval cells and the hyperplastic lesions of hepatocyte were very high and were not significantly altered by iron administration. Most liver cells had diploid or tetraploid DNA content, but there was an increase of diploidy as the development of hyperplastic lesions regardless of iron administration. The results indicate that the chemical carcinogen-induced hyperplastic lesions of hepatocyte do not accumulate iron, and that short-term iron administration does not affect the development of hyperplastic lesions and their proliferative activity and DNA ploidy.
