To evaluate correlation between the expression of neu and ras oncoprotein and epidermal growth factor receptor on breast carcinoma and other known prognostic factors, immunohisto-chemical studies were performed. Positive reaction for neu, which appeared as brown granular deposits along cell surface and cytoplasm of the tumor cells, was significantly correlated with the histological grade but not with other prognostic factors such as tumor size, lymph node me-tastasis, local recurrence, and estrogen and progesteron receptor status. Also granular deposits of ras were noted in the carcinoma cells in the cytoplasm, while the epithelaial cells of the normal lobule and duct showed negative reation. But expression of ras was not significantly associated ras with other prognostic factors. The reaction for EGFR was mostly negative on epithelial cells of both the normal lobule and duct, and was not significantly associated with other prognostic factors. The results suggested that expression of the neu oncoprotein is significantly associated with the histological grade of breast carcinoma, while the ras and the EGFR do not show significant prognostic value.

This study was performed to investigate the distribution of endotoxin in various organs after intraperitoneal injection of E. coli homogenator(0111:B4, 3X10(9)cells/200g of body weight). Sprague-Dawley rats were intraperitoneally injected with E. coli homogenator and sacrificed 1 and 3 hours after injection. The lung, liver, and kidney were immunohistochemically stained with avidin-biotin complex method and observed by light and electron microscopy. On the light microscopy, granular deposits of reaction products of immunohistochemical stain were found on the cytoplasmic membrane of endothelial cells and some of parenchymal cells of all organs observed. Electron microscopic study revealed finely granular reaction products on the surface of endothelial cells and some of parenchymal cells. The pinocytotic vesicles of endothelial cells demonstrated reaction products in the early phase of experiment. The distribution of reaction products were prominent in the liver among three organs. The Kupffer cells showed the most sensitive and strongest positive reaction. The hepatocytes and endothelial cells revealed weak positive reaction 3 hours later. The alveolar macrophages of the lung were also positive from the early phase of endotoxemia, while the pneumocytes and alveolar septa demonstrated weakly positive reaction in the later phase. The capillary endothelium of the kidney revealed positive reaction from the early phase. According to above results, it is concluded that the endotoxin entered into the systemic circulation was captured in the liver and lung. And both mononuclear phagocytic system and endothelial cells could be activated or damaged by endotoxin.

The purpose of this retrospective study was to evaluate the efficacy of arthroscopic repair of Bankart lesion using the biodegradable polyglyconate implant(Suretac) for the treatment of traumatic anterior shoulder instability. Although the arthroscopic procedure using the Suretac device has some technical advantages over others, there have been reports of the higher failure rate than open procedure. Eight shoulders in 8 patients who had traumatic anterior instability of the shoulder with Bankart lesion were managed with this procedure. They were followed up for average 2 years (range 1 year 4 months to 2 years 5 months). During the follow-up period, all the patients showed full range of motion of the shoulder without recurrence of instability. It was our impression that success rate of the procedure could be improved by careful selection of the patient, the accurate arthroscopic technique, and the good rehabilitation program.

A retrospective review of 102 patients with metastatic bone tumor seen at Hanyang University Hospital from 1986 to 1990 was performed. We analyzed the cases in the aspects of primary lesions, age and sex distributions, locations and number of metastatic foci, compared with those in the previous reports in Korea. l. 54.9% of the patients were male and 45.1% were female. The incidence of the metastatic bone tumors in female compared with the previous incidence before 1980's years was relatively increased. The peak age was in the 6th decade. The incidence younger than 50 years was decreased, and the incidence older than the 7th decade was relatively increased. 2. The main primary cancers were lung(40.2%), liver(11.8%), breast(10.8%), unknown(8.8%), and uterine cervix(6.9%) etc. In cases of lung cancer, the frequent histologic types were adenocarci noma, squamous cell carcinoma, and small cell carcinoma. 3. The vertebrae(56.9%), ribs(40.2%), femur(17.6%), pelvis(15.7%) were relatively frequent sites of metastasis which involved multiple metastasis. 4. Single metastasis(62.4%) was more frequent than multiple metastasis(37.6%). 5. In the primary cancers, the incidence in hepatoma of male was increasing, the incidence in lung cancer of female was relatively increasing, but the incidence in stomach cancer was decreasing.

This study was performed in order to explore the immunologic relationship between the skin lesions induced by the human serum and the lymphatic organs. For these purposes, the authors induced the dermatitis in the rabbits by the injections of pooled human serum with Freunds complete adjuvant into the skin, and administered prednisolone and azathioprine as immunosuppressive drugs to the rabbits. Immunologic asmy was performed by the measurement of the plasma ceIls and immunogobulin-bearing B lymphocytes in lymph node and spleen. The results were as follows: 1. By the injections of human serum pyroninophilic cells and immunoglobulining B lymphocytes in lymph node and spleen were increased. 2. By the administrations of prednisolone and azathioprine, pyroninophilic cells and immunoglobulin-bearing B lymphocytes in lymph node and spleen were all decre RSCd.
