We had experienced 2 cases of acute subdural hematoma due to vitaimin K(vit. K) deficiency. They were 44-and 42-day-old. After the adminstration of vit.K1, prolonged prothrombin time(PT) and activated partial thromboplastin time(APTT) were corrected, so the surgical treatment ws performed. We supposed the predisposing factors were breast feeding and unknown hepatic pathology. No complication remained to one infant but the other multiple cerebral infarctions. The etiology, pathogenesis, diagnosis, prevention are discussed. We insist on neonatal administration of vit. K1 for the prevention of bleeding tendency. If intracranial hemorrhage develops, we must keep in mind that the early neurosurgical intervention may be needed.

ICAM-l(Intercellular adhesion molecule-1) is an important early marker of immune activation and response. ICAM-1 is expressed on varous cell types and observed in a variety of diseases, including patients with asthma, melanoma, prostatic cancer, ovarian and colon cancer. Some authors demonstrated the expression of ICAM-1 protein in high-grade intraepithelial squamous neoplasia of cervix by immunohistochemistry and suggested that the expression was related to human papillomavirus infection. The aim of this study was to determine the serum levels of soluble intercellular adhesion molecule-1(sICAM-1) in patients with squamous cell carcinoma of the cervix, Serum levels of sICAM-1 were measured by enzyme-linked immunosorbent assay(ELISA), We evaluate invasive squamous cell carcinoma of the cervix (40), carcinoma in situ (16) and control (15) patients. Serum levels of sICAM-1 in healthy volunteers, in parients with carcinoma in situ and invasive cervical cancer were 150.1+/-41.3, 182.7+/-105.9, 189.8+/-60.0 ng/ml, respectively. Although the serum levels of sICAM-1 in patients with carcinoma in situ did not increase, serum levels of ICAM-1 in patients with invasive cervical cancer were significantly increased (control vs invasive cervical cancer, p < 0,05). From the above results, sICAM-1 is shed from the cancerous tissue in patients with squamous cell carcinoma of the cervix.

BACKGROUND: Specified clinical observations regarding skin changes in viral hepatitis have not yet been accomplished in Korea, especially in view of serotypes. OBJECTIVE: This study was conducted to identify various cutaneous manifestations of viral hepatitis according to viral serotypes and the stages of the disease. METHODS: We performed a clinical observation of cutaneous manifestations in 450 patients who were diagnosed with viral hepatitis. RESULTS: 1. Cutaneous manifestations were found in 383(85.1%) patients. Patients with a longer duration seemed to have skin lesions more frequently. 2. The frequency of cutaneous manifestations was highest in HAV(94.4%) and HBV(84.9%) serotypes. The most common cutaneous manifestation was pruritus(32.4%) in all studied subjects. In HBV hepatitic patients, the most common cutaneous manifestation was pruritus(35.4%), in HCV hepatitic patients, vasculitic purpura(74.5%), in HAV hepatitic patients, urticaria(88.8%), in the hepatitic patients with the mixed form, spider angioma(30.2%) and vasculitic purpura(30.2%). 3. Urticarial lesions in non-HCV hepatitis were of the lymphocytic vasculitis type but HCV hepatitis was associated with neutrophilic vasculitis. The purpuric lesions with HCV hepatitis were of the neutrophilic vasculitis type while lymphocytic vasculitis was present in non-HCV hepatitis. 4. The most severe pruritus was present in HBV hepatitic patients. CONCLUSION: The cutaneous manifestations in viral hepatitis have different clinical features depending on the viral types.

Reactive mesothelial cells are frequently found in the smear, of body fludid dffusion when associated with liver cirrhosis, pulmonary tuberculosis, congestive heart failure or pulmonary infarction. But it is not easy to differentiate these reactive mesothelial cells from macrophages or various types of malignant cells. In order to investigate the morphology of hyperplastic mesothelial cells, in comparison with the various types of malignant cells in the effusion, this experiment was designed. The tissue reaction was evoked by intraperitoneal injection of 2.5 ml of 2% Talcum suspension. The results obtained were as follows: 1) On light microscopic observation of the tissure, until 5 days, cytoplasm and nucleus of mesothelial cells became larger and nucleoi became prominent. After then, cytoplasm and nucleus became smaller and at 28 days after injection of Talcum suspension, cellular features became similar to those of normal ones. 2) On cytologic observation of touch print specimens, hyperplastic mesothelial cells became round to oval, and their cytoplasm became conspicuous. Nuclei were vesicular, and nucleoi were prominent. N/C ratio was decreased than normal. 3) On electron microscopic observation, hyperplastic mesothelial cells did not have microvilli, but had a few cytoplasmic globular projections, loosely approximated cellular junctions, larger and more abundant intracytoplaomic vesicles when compared with normal one. Chromatin clumping, irregular thickening of nuclear membrane and prominent nucleoi were also noted.

PURPOSE: Insulin-like growth factor-I (IGF-I) is an important mitogen in many types of malignancies. The purpose of this study was to evaluate the role of the IGF system on cell proliferation and cell death in mouse lung cancer cell lines (3LL). MATERIALS AND METHODS: Northern analysis was performed in 3LL cells. We evaluated the phosphorylation of IGF-I receptor (IGF-IR) with IGF-I stimulation. MTT assay was performed after treating 3LL cells with IGF-I and the treatment effect on cell death in the presence of anticancer drug was investigated. RESULTS: Northern analysis revealed the presence of IGF-I and IGF-IR mRNA expression in 3LL cells. IGF-I increased cellular proliferation in serum free media. IGF-I also stimulated the tyrosine phosphorylation of two proteins: one, with a molecular mass of 95 kDa, was the beta-subunit of IGF-IR; the other, with an approximate molecular mass of 185 kDa, was originally identified as the insulin receptor substrate-I (IRS-I). IGF-I at a low concentration inhibited the cell death induced by adriamycin. CONCLUSION: IGF-I, a mitogen through the phosphorylation of the IGF-IR beta-subunit, acts as a survival factor to inhibit cell death. Therefore, these findings suggest that IGF-I and IGF-IR are involved in both the cell proliferation and cell death associated with cancer cell growth.

BACKGROUND: IGF-I is an important mitogen in many types of malignancies. Tumors also express many IGF binding proteins, which modulate IGF action. The purpose of this study was to evaluaste the effect of IGF-I and IGFBP on cell proliferation in mouse lung cancer cells (3LL). METHODS: The cellular proliferation of 3LL with the treatment of growth factors was evaluated using MTT assay. Western ligand blot was performed in order to determine whether 3LL cells secrete IGFBPs and we evaluated the effect of IGFBP on cellular proliferation. RESULTS: The treatment of 3LL cells with IGF-I increased cellular proliferation in a serum free media. Western ligand blot of conditioned medium of 3LL with 125I-IGF-I demonstrated one single major band with an estimated molecular mass of 24 kDa. This band was identified as IGFBP-4 with immunoblot analysis using antisera. The addition of anti-IGFBP-4 antibody to abrogate the effect of IGFBP-4 resulted in increased cellular prolife ration suggesting that IGFBP-4 inhibits cell growth. CONCLUSION: IGF-I increases cellular proliferation, however the secreted IGFBP- 4 has an ingibitory function on cell growth in 3LL. These findings suggest that IGF-I and IGFBP are involved in the cell proliferation.

Since the anatomy of vocal fold and physiology of phonation are introduced, many surgical techniques for vocal fold disorders has advanced. Microflap and mini-microflap surgery were designed to protect the bare surface of the operated site. However, many new techniques have been based on common sense because of the absence of an accessible animal model with a vocal ligament. Therefore, authors studied to evaluate the differences of the results between mini-microflap surgery and microdissection surgery. Thirty-four mini-microflap surgeries(17 bilateral) and twenty-eight microdissection surgeries(14 bilateral) were performed on 31 patients. Patients' subjective evaluation and videostrobolaryngoscopic examination revealed that mini-microflap surgery was better than microdissection surgery. A mini-microflap surgery, as does limited mucosal resection, was more efficacious in the treatment of vocal nodules than microdissection surgery.
