    초록

    Contribution of histamine H1- and H2-receptors to the effect of compound 48/80, a potent histamine releaser, upon asphyxiation and body temperature in mice was investigated in the present experiments. Compound 48/80 showed an apparent protective potency against hypoxia and significantly prolonged the latencies for convulsions and death in a dose-dependent manner. Compound 48/80 also decreased the body temperature, which was in relation with the antihypoxic effect. Both the H1-receptor antagonist, dimethindene, and the H2-receptor antagonist, ranitidine, attenuated the hypothermic effect of compound 48/80, indicating the involvement of central histamine through both the H1- and H2-receptors. Ranitidine had no effect on the protective effect of compound 48/80 against hypoxia-induced lethality, whereas dimethindene completely antagonized it. These results suggest that the protective effect of compound 48/80 against hypoxia is mediated through histamine H1-receptors and is not related to its ability to induce hypothermia.

    Yonsei medical journal v.37 no.2 ,pp. 104 - 111 , 1996 , 0513-5796 ,

    초록

    The purpose of this study was to compare iron related indices in patients with iron deficiency anemia and chronic causative diseases between geriatric older than 65 years and adult, nongeriatric younger than 65 years groups. Iron deficiency anemia (IDA) cases with chronic disorders from Youngdong Severance hospital from June, 1991 to April, 1994, older than 65 years (17 cases), and younger than 65 years (29 cases) were analysed with iron related indices. Mean hemoglobin was 7.8 +/- 2.2 g/dl in geriatric IDA and 8.0 +/- 1.8 g/dl in adult IDA without significant difference. RDW value was 19.5 +/- 2.6 in geriatric IDA and 18.4 +/- 3.2 in adult IDA with no significant difference. Serum iron and transferrin saturation between geriatric IDA were 22.7 +/- 12.3 ug/dl, 6.7 +/- 4.1% and 28.6 +/- 16.6 ug/dl, 7.1 +/- 4.4% in adult IDA with no significant difference, but TIBC was significantly lower (P = 0.011) in geriatric IDA than in adult IDA patients (357.2 +/- 83.2, 413.6 +/- 54.0 ug/dl). In normal elderly people, serum ferritin was 152.5 +/- 95.4 ng/ml in male and 111.1 +/- 54.1 ng/ml in female with range 19.8 approximately 367.7 ng/ml in male and 11.7 approximately 238.7 ng/ml in female and was higher than that of normal adult in both sexes (147.0 +/- 108.0, 35.3 +/- 20.5 ng/ml) (P = 0.045). Serum ferritin in geriatric IDA was 13.8 +/- 11.8 ng/ml and 5.7 +/- 4.0 ng/ml in adult IDA with significant difference(P = 0.001). The Upper margin for geriatric IDA was 37 ng/ml with 95% confidence interval. In the diagnosis of geriatric IDA with causative diseases, we should consider that TIBC does not increase and the upper margin for serum ferritin is suggested to increases up to 37 ng/ml.

  3. [국내논문]   p53 protein expression in extrahepatic bile duct cancer.  

    Lee, Y C , Song, S Y , Chung, J B , Kang, J K , Park, I S
    Yonsei medical journal v.37 no.2 ,pp. 112 - 117 , 1996 , 0513-5796 ,

    초록

    p53 mutations, a tumor suppressor gene located on chromosome 17p, are the most common genetic alterations found in human cancers. Although the p53 expression or mutation has been investigated in a variety of cancers there have been very few studies in extrahepatic bile duct cancers. In this study, we investigated the immunohistochemical expression of p53 in formalin fixed paraffin embedded archival specimens of 36 extrahepatic bile duct cancers in which p53 expression was found in eighteen (50%) cases. There was no significant difference in age, gender, size of tumor, histologic grade, extent of tumor involvement, lymph node metastasis and tumor resectability according to p53 immunoreactivity. Comparison of survival duration according to p53 expression showed no significant difference. In conclusion, we reported 50 percent of p53 expression in extrahepatic bile duct cancers by immunohistochemical staining and we found no prognostic significance of p53 expression in dinicopathologic parameters.

  4. [국내논문]   The role of omentopexy in tracheal transplantation in dogs.  

    Park, Y S , Lee, D Y , Paik, H C , Bae, K M , Cho, S H
    Yonsei medical journal v.37 no.2 ,pp. 118 - 124 , 1996 , 0513-5796 ,

    초록

    The major step toward successful tracheal transplantation is revascularization of the grafted trachea. There are many reports that although omentopexy is an effective method to facilitate neo-vascularization in tracheal transplantations, the procedure has not been accepted universally in the transplantation field. It remains unclear whether an omentopexy can successfully revascularize tracheal graft regardless of the length of graft. This study was undertaken to assess the usefulness of omentopexy for long-segment(more than 4 cm) tracheal allotransplantation. We have performed six tracheal transplantations with omentopexy (group A) and four tracheal transplantations without omentopexy (group B) in mongrel dogs from July 1993 to February 1995. Five mid-portion tracheal rings were removed from ten donor dogs and ten corresponding tracheal rings were removed from the ten recipient dogs. The excised tracheal rings from the donors were transplanted to the recipient tracheal-excised sites. All the recipients were given cyclosporine, azathioprine, and prednisolone for immunosuppression in the post-operative period. The histologic results of all the surviving members of group B were better than those of the group A. These findings indicate that omentopexy has a limitation, it is not a major method for graft revascularization. Therefore the length of the tracheal graft was greater than 4.0 cm, for its viability, a longer tracheal graft requires some other blood supply aside from the omentopexy.

    Yonsei medical journal v.37 no.2 ,pp. 131 - 141 , 1996 , 0513-5796 ,

    초록

    Solid and papillary neoplasms of the pancreas, a rare tumor usually found in young female patients, seldom presents with metastasis since it is a tumor with low potential for malignancy. The prognosis for this lesion is much more favorable than that for other pancreatic neoplasms. In an attempt to understand the characteristics and prognosis of this lesion, we reviewed twenty cases treated at the Department of Surgery, Severance Hospital, Yonsei University from 1985 to 1994. The mean age of the patients was 25.6 years (range: 13 to 39 years), and 19 (95%) were women. Chief complaints were palpable mass (50%), pain (45%), and indigestion (5%). In laboratory studies, tumor markers, including CEA, CA125, CA19-9, and aFP were studied in eight patients, and found negative. Other laboratory findings were also nonspecific. These tumors may occur anywhere in the pancreas. In our studies, the tumor was most often located in the tail (45%), and the head (40%) of the pancreas. These were treated by distal pancreatectomy and splenectomy (55%), Whipple's operation (20%), pylorus preserving pancreatoduodenectomy (10%), enucleation (10%) or excision (5%). Significant morbidity or mortality was not observed during hospitalization, and no recurrence or malignant degeneration occurred during the mean follow-up period of 4 years (range: 1 month to 9 years). In conclusion, this study has suggested that the patients with a solid and papillary neoplasm of the pancreas have a good prognosis for successful treatment, if the disease is diagnosed early and the tumor is completely resected. A higher index of suspicion, and more aggressive diagnostic workups are needed in dealing with this disease entity.

  7. [국내논문]   Cyclin D1 protein expression in lung cancer.  

    Yang, W I , Chung, K Y , Shin, D H , Kim, Y B
    Yonsei medical journal v.37 no.2 ,pp. 142 - 150 , 1996 , 0513-5796 ,

    초록

    Cyclin D1, a G1 cyclin, has been implicated in the oncogenesis of various types of malignancies via deregulation of cell cycles. Amplification of cyclin D1 as a part of 11q13 amplicon has been reported in lung cancer as well as a subset of carcinomas arising from various organs including breast, head and neck, and esophagus. In addition to its role as an oncogene, several recent studies have suggested that amplification is indicative of poor prognosis. In this study we examined the cyclin D1 protein expression in 102 consecutive cases of lung cancers using the microwave enhanced immunohistochemical staining method and correlated the data with the histologic subtype and grade, Ki-67 (MIB-1) labeling index, and survival. Nuclear positive staining was observed in 18 cases (18 %) of lung cancers. Although squamous cell carcinoma demonstrated a higher rate of expression (12 /58, 21%), three of 33 adenocarcinomas (9%) revealed overexpression and both adenocarcinoma and squamous cell carcinoma components within the adenosquamous carcinoma showed nuclear staining. There was no correlation between cyclin D1 overexpression and histologic grade, Ki-67 (MIB-1) labeling index, and survival. These observations indicate that cyclin D1 protein overexpression might be implicated in the oncogenesis of the various histologic types of non-small cell lung carcinomas but it has no usefulness as a prognostic marker.

    Yonsei medical journal v.37 no.2 ,pp. 151 - 157 , 1996 , 0513-5796 ,

    초록

    Paraesophageal hernia comprises only 2 approximately 5% of all hiatal hernias but is prone to incarceration and strangulation. For this reason they must be recognized and repaired as expeditiously as possible. The laparoscopic approach has already been successfully applied to the repair of the more common sliding hiatal hernia and it seems reasonable to propose that the paraesophageal hernia, provided it is not complicated, might also be repaired by the laparoscopic technique. We present here a case of paraesophageal hernia which has been successfully repaired by the laparoscopic approach. A 73-year-old female suffering from postprandial fullness in the retrosternal area was diagnosed preoperatively with paraesophageal hiatal hernia with gastroesophageal acid reflux and was submitted for laparoscopic repair. The procedure entailed reduction of the hernia, mobilization of the esophagogastric junction with crural repair and partial fundoplication. At the 9th-month follow-up, the patient had remained asymptomatic and follow-up studies revealed no evidence of hernia or acid reflux. As a result of this favorable experience with minimal morbidity, early hospital discharge, and effective control of symptoms without adverse sequalae, laparoscopic repair can be considered as the curative and minimal invasive method in the management of paraesophageal hernia.

    초록

    We recently experienced a case of spontaneous perforation of infected necrosis into the colon and duodenum during the course of acute pancreatitis in a 63 year-old male patient. Enteric perforations or fistulas in the setting of acute pancreatitis implicate severe underlying pathology and have substantial morbidity and mortality. In the meantime it has generally been accepted that infected pancreatic or peripancreatic necrosis should be managed surgically as soon as possible. Enteric perforations in the present case contributed to transient improvement of the patient's infection sign and condition, and thus an early operation was able to be avoided. Delayed surgical management resulted in complete recovery of the patient without postoperative morbidity. Herein we report an unusual complication of acute pancreatitis.
