The author investigated the allergic contact dermatitis patients which visited our out-patient skin dispensary during 1969 and 1970. The patients were evaluated arcording to age, sex and cause of the disease. Furthermore, the patients were analysed as to the causative allergic contact factors by clinical inspection and history. The causes were confirmed by the patch test which was done on 88 of the allergic contact dermatitis patients. It is believed that patch test is clinically a most reliable procedure for the determination of responsible antigenic substance in allergic contact dermatitis and the positive reactions may be labelled as latent or potential hypersensitivity(Hjorth et al, 1968; Maibach, 1965). There is a group of chemicals used on the so-called routine screening patch test tray, which have proved to be frcquent causes of allergic contact dermatitis. Many diagnostic groups of chemicals and therapeutic trays, shoe trays, metal trays, etc., in addition to the standard routine screening patch test tray are used. Certain allergens seem to cause dermatitis in all countries hut many sensitizers vary from one country to anothcr (Calnan, 1955), The author has tried to establish a standard routine screening patch test tray fitted to our country according to the basic consideration used with standard routine patch test trays of the Skin and Cancer Unit, New York University Hospital. Paraphenylene diamine, ammoniated mercury, mercury bichloride, formalin, crude coal tar, potassium dichromate and mercaptobenzothiazole were the most potent sensitizers. These chemicals must be included in our standard screening routine patch test tray. However, the patch test results and the present clinical dermatitis (i.e. cosmetic dermatitis and rubber or leather dermatitis) did not coincide. Further investigation for the establishment of a proper stanard patch test tray for Korea should be carried out.

BACKGROUND: Autoimmune hemolytic anemias are characterized by autoantibodies recognizing antigens on the Individual's own red blood cells, resulting in immune- mediated hemolysis. Blood transfusions have been regarded as hazardous in patients with autoimmune hemolytic anemia (AIHA) because of potential intensification of hemolysis and a presumed high incidence of alloimmunization. METHODS: We examined the pretransfusion and posttransfusion hemoglobin levels in 6 patients with autoantibodies in their sera, which showed panagglutinations with all bloods tested in the compatibility testing. They received 'least' incompatible blood because of inability to find compatible blood. RESULTS: When we compared pretransfusion hemoglobin level with posttransfusion hemoglobin level, in 5 of 6 patients with AIHA, the hemoglobin levels were increased after red cell transfusion. 4 patient who did not respond to transfusion therapy initially had an increase in hemoglobin level after steroid treatment. Any signs or symptoms indicating hemolytic transfusion reaction were not observed ducting the transfusion period in all patients. CONCLUSIONS: The decision to transfuse in AIHA should consider multiple factors including the patient's clinical status, the potential benefit of transfusion, the potential response to other therapeutic modalities, but must never be regarded as contraindicated, even though the compatibility test may be strongly incompatible.

Among the causes of pure red cell aplasia, human parvovirus B19 has been shown to be cytotoxic to erythroid progenitor cells in the bone marrow associated with chronic hemolytic anemia with rapidly dividing erythroids and persistently to be suppression of erythropoiesis in immunocompromised individuals related with failure to produce neutralizing antibody to the virus. In a patient with hereditary spherocytosis presenting acute onset of reticulocytopenia during hospitalization, who had shown severe anemia and prodromal symptoms including fever, fatigue and dizziness, infection of parvovirus Bl9 was proven by the presence of IgM and IgG antibodies to parvovirus Bl9, the detection of viral DNA using PCR technique in her serum and the decreased erythroid cells, especially late normoblasts in bone marrow, Also in the other who was diagnosed as hereditary elliptocytosis and complained of fever, headache, abdominal pain and diarrhea, an episode of reticulocytopenia and the nearly absence of late normoblasts in the bone marrow were observed. IgM antibodies to parvovirus Bl9 and the viral DNA were detected in her serum, too.

PURPOSE: We report on a novel method and outcomes of laparoscopic gastric tubing with pyloromyotomy. METHODS: The abdominal procedure includes laparoscopic gastric mobilization, celiac axis lymph node dissection, formation of the gastric tube, and pyloromyotomy. Between January 2009 and April 2013, our minimally invasive esophagectomy (MIE) was performed on 54 patients with esophageal cancer. The short-term outcomes, including postoperative complications, were analyzed. RESULTS: There were no cases of conversion to open surgery. Of 54 patients, 52 patients had squamous cell carcinoma (SCC) and two had adenocarcinoma. The total operative time was 349.8+/-77.4 minutes, of which 90.6+/-27.6 minutes was required for the abdominal procedure. The mean estimated operative blood loss during the abdominal procedure was 40.0+/-355.5 ml. The postoperative complication rate was 24.1%; three patients died of pneumonia. CONCLUSION: Laparoscopic gastric tubing with pyloromyotomy is a feasible and safe treatm ent option for patients with esophageal cancer.

A Clinical analysis was carried out with 340 cases of craniocerebral injuries under 15 years of age, admitted at the Department of Neurosurgery, Seoul National University Hospital in 12 years between Jan., 1987 and Dec., 1969. The matrial was classified four groups according to main lesions, i.e. (1) mild cerebral contusion without skull fractures. (2) moderate or severe cerebral contusion without skull fractures. (3) various types of skull fractures. (4) intracranial hemorrhagic lesions, representing such lesions as follows: a. epidural hematoma, b. subdural hematoma, c. subdural hygroma, d. intracerebral hematoma, e. traumatic subarachnoid hemorrhage. The results were as follows: 1) The age incidence was greatest in 6 years of age, and 120 cases (32.6% of the total) were included in the age group between four and six. 2) Males outnumbered females by almost 2 to 1. 3) The accident occurred mostly between 1 p.m. and 4 p.m. in a day. 4) The craniocerebral injuries were caused by traffic accident(173 cases; 50.8%), falls from heights(108 cases; 31.8%), hit(55 cases; 10.9%), firearms(2 cases; 0.6%) and birth injury (2 cases; 0.6%). 5) Early convulsion was the frequent symptom in the age group between 2 and 7. It was felt that convulsions frequently occurred in epidural and subdural hematoma patients. 6) Forty eight per cent of patients had no deterioration of consciousness on admission examination. 7) Epidural hematoma was the common finding in most of the depressed skull fracture cases. 8) The location of skull fractures in the order of frequency were parietal, temporal, frontal and occipital bone. 9) The epidural hematoma was most common lesion in the 13 to 15 year-old group. 10) The over-all mortality rate was 7.1%. In the surgical group(79 cases) the operative mortality was 11.4%(9 cases): the mortality rate of the subdural hematoma, 25.0%(3 cases); the epidural hematoma, 11.1%(2 cases); the compound depressed fracture, 7.8%(2 cases). In the non-surgical group(261 cases) it was 5.8%. The mortality rate of those who and been unconscious after injuries was significantly high(75.0%). 11) The period of hospitalization was two weeks on an average.

PURPOSE: Recent studies indicate that Fas and Fas Ligand (Fas-L) are implicated in autoimmune endocrine diseases and tumors of the thyroid. In this study we tried to elucidate the expression stati of Fas and Fas-L in some kinds of thyroid neoplasms, and their relationships with 4 prognostic factors in papillary thyroid cancer (i.e., size, lymph node metastasis, capsule invasion, age). METHODS: 66 cases of thyroid neoplasm including 45 cases of papillary cancer (PTC), 3 of a follicular cancer (FTC), 1 of a poorly differentiated cancer (PDC), 1 of a undifferentiated cancer (UC), 7 of follicular adenoma (FA), and 9 of nodular hyperplasia (NH) were examined, and estimated as negative, weak positive and strong positive about the Fas and Fas-L expression by the immunohistochemical staining intensities. We then collected and compared the differrences between benign and malignant tumors. The expressions of Fas and Fas-L in papillary thyroid cancers were evaluated relating to the differences in the prognostic factors (i.e., the size, lymph node status, capsule invasion, and age of the patients). RESULTS: Malignant thyroid tumors revealed stronger staining intensity than benign neoplasms. In papillary thyroid cancers, Fas-L staining intensities were significantly stronger in the cases with perithyroidal lymph node metastasis, or in those of 45 years old or over than in those with no lymph node metastasis, or younger than 45 years. CONCLUSION: Both Fas and Fas-L are implicated in thyroid tumorigenesis and revealed stronger staining intensities in malignant than benign tumors, and the Fas-L staining intensities may have some prognostic implications at least in papillary thyroid cancers.

Institute of Cancer Research (ICR) mice have been widely used in various research fields including toxicology, oncology, pharmacology, and pharmaceutical product safety testing for decades. However, annual tendency of research papers involving ICR mice in various biomedical fields has not been previously analyzed. In this study, we examined the numbers of papers that used ICR mice as experimental animals in the social science, natural science, engineering, medicine-pharmacy, marine agriculture-fishery, and art-kinesiology fields by analyzing big data. Numbers of ICR mouse-used papers gradually increased from 1961 to 2014, but small decreases were observed in 2015 and 2016. The largest number of ICR-used papers were published in the medicine-pharmacy field, followed by natural science and art-kinesiology fields. There were no ICR mouse-used papers in other fields. Furthermore, ICR mice have been widely employed in cell biology studies within the natural science field as well as in biochemistry and pathology in the medicine-pharmacy field. Few ICR mouse-used papers were published in exercise biochemistry and exercise nutrition in the art-kinesiology field. Regardless in most fields, the total numbers of published papers involving ICR mice were higher in 2014 than in other years, although the numbers in some fields including dentistry, veterinary science, and dermatology were high in 2016. Taken together, the present study shows that various ICR stocks, including Korl:ICR mice, are widely employed as experimental animals in various biomedical research fields.
