BACKGROUND: The diagnostic methods of atherosclerosis before the development of clinical diseases(such as angina pectoris, myocardial infarction, cerebral infarction or peripheral vascular disease) are rather limited. The Russian doctors made the observations through the autopsy studies that there is a good correlation between the degree of atherosclersis or the cholesterol content of the aorta and the cholesterol content of the skin. We tried to investigate whether there is a significant degree of differences in the cholesterol content of the skin between the patietns with atherosclerotic disease(disease group), the patients who have not developed the clinical atheroscleric disease but have risk factors for atherosclerosis(risk group), and the normal control patients(normal group). METHODS: The skin choleterol was extracted from the palm of the hands by the closed contact with the chemicals. RESULTS: 1) The skin cholesterol was 2.77+/-1.08/microg/cm2in the disease group, 2.47+/-1.13microg/cm2in the risk group, and 1.84+/-0.60microg/cm2in the control group, The difference between the disease group and the normal group was significant(p<0.001), but the difference between the disease group and the risk group was not significant. 2) When the skin cholesterol of 2.1microg/cm2was used as a criterion. its sensitivity and specificity to predict either the disease gorup or the risk group was 66.1% and 70.8%. 3) In addition to the skin cholesterol of 2.1microg/cm2or more, if we add a criteria of cholesterol >220mg/dl, or TC/HDL-C ratio >4:1, or Apo B/A ratio >0.9, these separated the normal group from either the disease group or risk group much beter. 4) There was no significant correlation between the skin cholesterol and blood cholesterol. Also there were not any significant correlations between the skin cholesterol and the LDL cholesterol, TC/HDL-C ratio or Apo B/A ratio. CONCLUSION: On the basis of the above mentioned observations made by the Russian doctors and the present data showing significantly higher skin cholesterol level in the disease and risk group compared with normal control group, and little significant correlation between the skin cholesterol and the blood cholesterol level, it is likely that the skin cholesterol can be considered as an independent risk index for the atherosclerotic disease. Measuring the skin cholesterol by extraction of cholesterol from the palms of the hands may help predicting the presence or the risks of the atherosclerotic diseases.

Hemangiopericytoma was first described by Stout & Murray in 1942 and was an uncommon soft tissue tumor thought to be derived from vascular pericytes. Approximately 10-15% of the cases occur in children have a propensity to develop in the region of head, neck and lower extremities. We experienced a case of congenital hemangiopericytoma of small bowel in a male neonate who showed vomiting and abdorninal distension. We reported a case of congenital hemangiopericytoma of small bowel with brief review of related literature.

OBJECTIVE: To analyze the relationship between the degree of expression of E-cadherin and presence of high risk prognostic factors (lymph node metastasis or parametrium involvement), clinical stages and pathologic types in invasive cervical cancer. METHODS: An immunohistochemical technique has been applied to formalin-fixed, paraffin- embedded samples from 20 radical hysterectomy without risk factors and 16 radical hysterectomy with risk factors. The degree of expressions of E-cadherin immunostaining was compared with the International Federation of Gynecology and Obstetrics (FIGO) stage, presence of high risk prognostic factors, and pathologic types. RESULTS: The difference of the degree of expression of E-cadherin was not statistically significant between high-risk group (lymph node metastasis or parametrium invasion) and non-risk group. The difference of the degree of expression of E-cadherin was not statistically significant according to clinical stages and variable pathologic types either. CONCLUSIONS: These results suggest that the degree of the expression of E-cadherin has no relationship with known high risk prognostic factors, clinical stages and pathologic types in invasive cervical cancer.

PURPOSE: We measured pulmonary epithelial permeability by Tc-DTPA radioaerosol clearance in patients with diabetes and correlated with the presence of microangiopathy to understand the pathophysiology of pulmonary microangiopathy and evaluate Tc-DTPA radioaerosol clearance as a diagnostic test to assess pulmonary microangiopathy. MATERIALS AND METHODS: We performed ' Tc-DTPA radioaerosol scan in 10 normal subjects, 10 asym-ptomatic smokers, 20 diabetic patients without history of smoking (10 with microangiopathy, 10 without microangiopathy). Tc-DTPA clearance half-time (T1/2) was calculated, then compared with the result of chest radiography and pulmonary function test. RESULTS: Chest radiography and pulmonary function test were normal in all subjects. There were no significant difference of clinical or laboratory characteristics between these groups except age. The diabetic patients with micraangiopathy were significantly older (p<0.05). The T1/2of normal subjects and asyrnptomatic smokers were significantly different (65.2+23.7min vs 39.6+9.8min, p<0.05). For diabetic patients with microangiopathy, the T, was 90 5+46.5min and significantly delayed when compared with those of normals and asymptomatic smokers (p<0.05). However, the T1/2of diabetic patients without microangiopathy, 70.0+12.7 min, was not significantly different from those of normals or asyrnptomatic smokers (p>0.05). No significant correlation was found between the T1/2and spirometric parameters including DLcc>, FVC, FEV>, FEV(/FVC (%) and FEF)5-75g in all subjects, and between the T1/2 and duration of diabetes in diabetic patients. CONCLUSION: Eventhough the influence of age cant be excluded, delayed Tc-DTPA clearance half-time (T1/2)in diabetic patients with microangiopathy indicates decreased pulmonary cspillary permeability as one of the pathophysiologic results of pulmonary microangiopaththy. Further studies are needed in larger number of age matched control and diabetic patients to evaluate the diagnostic efficacy.
