Nocodazole is an anticancer agent, well-known for its antimetastatic activity that acts on microtubules, microfilaments and extracellular matrix proteins. Hela, Hep G2, A549, L929, and NIH/3T3 cell lines were cultivated in alpha-MEM with 3microM or 30microM nocodazole. To investigate the mechanism of nocodazole preventing tumor cell metastasis, the influences of nocodazole on the amounts of glycoprotein, fibronectin, laminin and actin were investigated using PAS staining and PAP technique at light microscopic level. Two designed models ; coverglass and 3-day-old rat heart fragments models, were used in observing the invasiveness of cancer cells. Partitularly the three-dimensional model coculturing cell lines and heart fragment was used in evaluating the migration and/or proliferation or the invasiveness of cell around the fragment, and observed under inverted or bright field light microscope. The amount of glycoprotein of all cell-lines increased in cells of groups treated with nocedazole for 1, 2 and 3 day. The amounts of fibronectin usually increased in cells of groups treated with nocodazole for 1, 2 and 3 day. The amounts of laminin increased in cells of groups treated with nocodazole. The amounts of actin usually increased in cells of groups treated with nocodazole for 1, 2 and 3 days. With the prolonging of nocodazole-treatment time in two dimensional model using coverglass, the cells of control group except Hep G2 cells formed monolayer in cell-free zone according to migration or proliferation of many cells. But only a few cells of experimental groups migrated or proliferated into cell-free zone. In rat heart fragment model the cells of control group showed the invasiveness into the fragment but few or none of the cells from experimental groups attached around the fragment. Taken together, nocodazole increased the synthesis of fibronectin and laminin in cells in place of depolymerizing microtubules. Therefore, the amounts of extracellular matrix proteins in the extracellular space increased. And the increase amounts of actin connected to the extracellular matrix proteins through the integrin of plasma membrane seemed to strengthen cell attachment because of accordance between the orientation of actin and extracellular matrix proteins. Since it is important for cancer cells` metastasis to secrete various enzymes to pass through extracellular matrix proteins, it is expected more difficult for the cells to metastasize into other regions due to the increase of extracellular matrix proteins. As a result of confirmation of antiinvasive actions using two kinds of model, nocodazole seems to be a valuable anti-metastatic agent by supressing the cell motility and consequently, the invasiveness into the fragment. Nocodazole at concentration of 3microM will be probably anticipated antimetastatic activity reflecting that the effects of nocodazole between 3microM and 30microM groups had no differences.

We report a case of hepatocellular carcinoma presented with severe hypoglycemia. Computerized tomography and ultrasonography revealed a massive bilateral tumor with portal vein thrombosis. The levels of IGF-I (113 ng/mL) and IGFBP- (815 ng/mL) measured in the plasma, were lower than normal range. There was strong immunoreactivity of IGF- and IGF-I in immunohistochemical stain of tumor cells.

Fractures of the phalanges of the hand are very common. Many are minor and likely to have a good result. However many other phalangeal fractures cause significant and prolonged disability. Non-union of the tubular bones of the hand are uncommon occurrence, but are often associated with functional deficits. The authors have reviewed 7 cases of non-union of the phalanges which were treated in the department of orthopaedic surgery, National Medical Center from 1978 to 1985. The results were summarized as follows: 1. The non-union of phalangeal bone was defined by clinical symptoms and signs and roentgenological examination. 2. The incidence of non-union of phalangeal bone fractures was 0.9% (7/771 cases.) 3. of 7 patients, there were 6 in male and 1 in female. 4. Non-union occurred more commonly in the second decade and the group between 10 and 30 years of age. 5. Seven cases, all were the right handed, but injury was developed in the left hands except two cases. 6. The causes of non-union were thought as open wound (7 cases), type of fracture (simple or comminution:3 cases), inadequate immobilization (4 cases) and overtraction (1 case). 7. of 7 cases, 4 cases were treated with bone peg graft and K-wire fixation and 2 cases with excision of distal fragment. 8. The clinical union was 9 weeks in average.

Anaphylaxis is a life - threatening syndrome elicited in a hypersensitive individual on subsequent exposure to a sensitizing antigen with, reactions ranging widely in severity from mild pruritus and criteria to shock and death. Anaphylaxis occurs in the United States at rates estimated to be as high as one in every 3000 inpatients and may account for more than 500 deaths annually. Preparations of kelp Laminaria digitata are used as tents in gynecologic procedures to dilate the cervix, and the kelp consists principally of a glucagon carbohydrate called laminarin. Laminarin is thought to function as the active ingredient in dilatation by changing osmotic pressure or uterine prostaglandin metabolism. The tent is inserted into the cervix several hours before the procedure. As the cervix desiccates and dilates, the tent develops an hourglass shape. Recently, we experienced one patient with anaphylaxis to laminaria diagnosed by skin test and showing good response to treatment.

Lung transplantation has been successfully employed for variety of obstructive lung disease. Single lung transplantation has become a therapeutic option for end-stage obstructive lung disease. The patient, a 57 year old man with emphysema, suffered from severe dyspnea, which progressively aggravated him for the last three years. A single lung transplantation was performed from a young brain-dead donor on April 7th, 1999 in the department of thoracic surgery, Respiratory Center, Yongdong Severance hospital, yonsei University. The immunosuppressive regimen was based on cyclosporine A and azathioprine from beginning, adding steroid. Single lung transplantation was feasible and beneficial in patients with end-stage emphysema.

So-called sclerosing hemangioma of the lung is a rare benign neoplasm which usually presents with a coin lesion detected through routine chest X-ray. We report two cases showing characteristic cytologic appearances which have been rarely reported. Both cases were young females with coin lesions in the lung. Fine needle aspiration of each case revealed unique but some different cytologic features. Case 1 showed bland-looking polygonal epithelial cells resembling bronchioloalveolar cells having pre- dominantly papillary configurations with loosely arranged solid sheets or isolated cells. Cytoplasms were plump, cyanophilic, and finely granular, with eccentric nuclei, The nuclei were usually monotonous, round-to-ovoid, and vesicular with a small but conspicuous nucleolus. In comparison to case 1, case 2 revealed largely loose pavement-like solid sheets or clusters rather than papillary patterns in the hemorrhagic background. The size of tumor cells were a little smaller than that of case 1. Bronchioloalveolar carcinoma and papillary adenocarcinoma of metastatic origin were considered to be one of the important differential diagnoses with these cytologic features. Histologically, both cases exhibited findings compatible with so-called sclerosing hemangioma of the lung.
