Met protein is a transmembrane 190 kD heterodimer with tyrosine kinase activity, encoded by c-Met oncogene. It serves as a high affinity receptor for hepatocyte growth factor (HGF)/scatter factor (SF), a cytokine which stimulates cell proliferation, motility, and invasion. In this study, we immunohistochemically evaluated the expression of Met/hepatocyte growth factor receptor in colorectal cancers. Met protein was expressed in 31 of 72 patients (43.1%). The staining pattern was cytoplasmic in nature, present throughout the tumor, and showed variable intensity from case to case. The relationship between the expression rate and intensity, and age and sex of patients, tumor size (p=0.645), tumor site (p=0.902) and tumor differentiation (p=0.844) was not statistically significant. The expression rate and intensity were significantly correlated with lymphovascular invasion (p=0.001), lymph node metastasis (p=0.010), depth of invasion (0.019), and stage (p=0.023). Cytoplasmic accumulation of Met protein was not associated with enhanced PCNA index of tumor cells (p=0.052). These results suggest that Met protein may play an important role in the invasion and metastasis of colorectal cancer cells.

To evaluate the intractability of partial epileptic patients by variables, the author studied 113 patients (uncontrolled: 45, controlled: 68) who were admitted to the Department of Neurology, College of Medicine, Yeungnam University from January, 1991 to August, 1993. The results were as follows. The items related to complex partial seizures, multiple seizure types and a histories of status epilepticus or clusters of seizures were significantly associated with drug-refractoriness (p<0.01). A high frequency of seizures before evaluation was associated with a poor outcome(p<0.01). The presences of known etiology of seizures, neurologic abnormalities and psychiatric disturbance were associated with limited treatment responses(p<0.01, p<0.05, p<0.01). An abnormal EEG findings such as background slowing, focal slowing, epileptiform discharges or secondarily bilateral synchrony were statistically significant (p<0.01). Age at onset, sex, distribution of epileptic foci, duration of seizure before evaluation, family history and abnormal neuroradiologic findings were not statistically significant. By these results, it was suggested that having at least four factors of the above variables were associated with limited treatment response.

The Measurement of CSF glucose and CSF glucose-to-blood glucose ratio is a very useful laboratory test for the differential diagnosis of meningitis. We have observed the change of blood glucose & CSF glucose-to-blood glucose ratio according to the time of blood sampling in 84 patients with aseptic meningitis who had been admitted to the department of pediatrics, Dong Kang hospital from May 1993 to June 1993. The results obtained were as follows: 1) The blood glucose level examined with blood sample drawn just before lumbar puncture and one just after lumbar puncture was 98.29+/-16.20mg/dl and 106.49+/-19.47mg/dl, respectively. 2) The blood glucose level examined with blood sample drawn just before lumbar puncture and one 30 min. after lumbar puncture was 96.47+/-21.52mg/dl and 117.00+/-22.12mg/dl, respectively. 3) The CSF glucose-to-blood glucose ratios examined with blood sample drawn just before lumbar puncture and one just after lumbar puncture was 67.70+/-12.40% and 62.83+/-12.62%, respectively. 4) The CSF glucose-to-blood glucose ratios examined with blood sample drawn just before lumbar puncture and one just after lumbar puncture was 70.10+/-21.77% and 56.35+/-13.75%, reskpectively. We concluded that a simultaneous blood glucose level should be taken just before lumbar puncture.

Norfloxacin is a new broad spectrum of antibacterial activity against both Gram-positive and Gram. negative bacteria. After oral administration of Norfloxacin, it produces high concentrations in the urine, so it has the excellent effect for the treatment of urinary tract infection. Norfloxacin was studied with respect to clinical effect in 115 patients with the urinary tract infection and the following results were obtained. 1. Excellent efficacy was 53% and efficacy rate was 90% in upper urinary tract infection(UTI). Efficacy rate for 20 patients with upper UTI without the underlying disease was 100%, and in 29 patients with underlying disease efficacy rate was 83%. 2. In upper UTI resistant for other antibiotics, efficacy rate was 78%. 3. In lower UTI excellent efficacy rate was 36% and efficacy rate was 71%. In gonococcal urethritis excellent efficacy rate was 76% and efficacy rate was 88%. 4. Eliminated rate of bacteria on culture findings were E. coli 93%, pseudononas 89%, proteus 100%, klebsiella 80%, gonococcus 88% and staphylococcus 80%. 5. Mild side effects such as epigastric pain, nausea, dizziness and itching sensation were seen in 5 cases. We consider Neutam-400 is one of the most effective agents in urinary tract infection.

The purpose of this study was to compare dietitians' with cooks' actual sterilization performance for improving points of sanitation practices of cooking instruments and facilities in Kyonggi Province school foodservices. A total of 400 questionnaires were mailed to the dietitians and the cooks at elementary and middle schools in Kyonggi Province. Finally, 140 dietitians and 140 cooks replied by making a total of 280 replies(70%). The results of this study found that the cooks' attitudes toward the sterilization of the vegetable cutter body, multiple shelf, and distributing cart showed higher frequencies than the dietitians'. Cooks disinfected the vegetable cutter blade, multiple shelf, distributing cart, cook's aprons, and 'L' transporting cart better than dietitians' guides expected. In the sterilization method, cooks performed better than indicated when cooking with rubber gloves. The most difficult thing in dietitians' managing sterilization was the lack of cooking facilities and instruments. They strongly demanded the detailed explanatory notes according to their own Cities and Provinces and the circumstantial manual of disinfection parts in School Foodservice Sanitary Management Guide. There were possibilities of food-poisoning, infection and safety incidents due to the budgetary shortage of cooking facilities and instruments.

PURPOSE: To evaluate the role of CT in the diagnosis of bowel and mesenteric injury we studied the CT findings and its usefulness in patients of abdominal trauma. MATERIALS AND METHODS: CT scans of 27 patients who were confirmed to have bowel and/or mesenteric injury due to abdominal trauma were analyzed retrospectively. Of these 27 patients 15 had bowel injury only and 12 had both bowel and mesenteric injury. CT findings analysed were bowel wall thickening, presence or absence of highly attenuated bowel wall, sentinel clot, mesenteric infiltration, peritoneal fluid collection and free intraabdominal air in cases with bowel injury only and with both bowel and mesenteric injury respectively. Ten patients had other accompanying abdominal injuries, such as liver, spleen, pancreas, kidney, bladder injuries, intraperitoneal abscess or retroperitoneal hemorrhage. RESULTS: Findings observed were bowel wall thickening in 23 cases(85%), peritoneal fluid collection in 21 (78%), highly attenuated bowel wall in 19(70%), mesenteric infiltration in 17(63%), free intraperitoneal air in 10 (37%) and sentinel clot in 7(26%). Pneumoperioneum were observed in 10 of 24 patients(41.7%) having bowel perforation. Two cases did not show any CT findings suggesting bowel and/or mesenteric injury. There was no significant difference in the prevalence of the CT findings between the patient group with bowel injury only and the patient group with both bowel and meseneric injury. CONCLUSION: CT scan is a useful tool in evaluating the degree and extent of bowel and/or mesenteric injury as well as in planning the patient's management.

PURPOSE: This study was conducted to compare the changes in the levels of liver enzymes after providing health education to workers. METHODS: Among 909 electronics-manufacturing workers, 96 (10.6%) workers had abnormal liver functions. Of these, male workers were randomly assigned into either the health education experimental group (48 [52.2%]) or the control group (44 [47.8%]). Depending on the level of participation in the health education, workers in the experimental group were classified into the participation (32 [34.8%]) and non-participation groups (16 [17.4%]). Changes in the levels of liver enzymes were compared among three groups. RESULTS: The changes in the levels of gamma-glutamyltransferase (r-GTP) in the participation, non-participation, and control groups were -25.3+/-54.5 IU/L, -4.4+/-24.1 IU/L, and -5.3+/-38.8 IU/L, respectively (p=.036). Aspartate transaminase, alanine transaminase, waist circumference, body mass index, daily alcohol consumption, weekly exercise, and changes in smoking habits in the 3 groups did not differ significantly. In the multiple linear regression analysis, the variable of education participation revealed a significant regression coefficient of -25.10 when the change in r-GTP levels was the dependent variable. CONCLUSION: A brief health education targeted towards the management of liver disease among workers improved r-GTP levels.

We reviewed eight solitary fibrous tumors occurring at sites other than pleura (three orbit, two retroperitoneum, one each hard palate, thyroid, and tongue) which shared the histologic and immunohistochemical features of solitary fibrous tumors of pleura. Six patients were women, and two were men, aged from 26 to 74 years. The tumors ranging from 1.5 to 19 cm in diameter presented as well-circumscribed, unencapsulated, soft to rubbery tissue masses. Histologically they were characterized by a proliferation of spindle or ovoid cells intervened by a dense bundles of collagen. A variety of growth patterns was identified but the so-called patternless pattern was the predominant one. One tumor exhibited highly cellular sarcomatous areas with extensive necrosis, which was diagnosed as malignant solitary fibrous tumor. Immunohistochemical studies showed that all of the tumors were strongly positive for both CD34 and vimentin, but negative for cytokeratin, S-100 protein, EMA, and desmin. One case examined ultrastructurally showed features of fibroblast. All but one showed no evidence of recurrence or metastasis over follow-up period of 14 to 32 months. We conclude that extrapleural solitary fibrous tumors represent a distinct mesenchymal tumor with variable histologic features and should be differentiated from other spindle cell mesenchymal tumors.
