It is evident that an elevation of airway albumin excreation rate without clinical proteinuria strongly predicts a later progression on diabetic renal disease. So we studied the correlation between Microalbumin checkly RIA & Micral-Test®. We collected urine between 08:00 h and 08:00 h next day and then checked microalbuminuria by radioimmunoassay method and Micral-Test® The results are as follows: 1. There was significant correlation between microalbuminuria checked by RIA & Micral-Test® 2. There was poor correlation between diabetes duration or HV-A1c and maximal change in albumin excreation rate. 3. So we concluded that Micral-Test® can be used in laboratory instead of RIA.

Mullerian Mucinous papillary Cyatadenernas of Borderline tumor(MMBT) is lined by mucinous epithelium of endocervical type and is characterized by papillae architecturally similer to those of serous horderline tumors, It has been described rarely in the literature, Thia case was reported with a brief review of the concerened literatures. It has important clinical and pathological diBerences from mucinous birderline tumors with intestinal differentiation, but has many similatities to mixed epithelial borderline tumora of Mulierian type. Recently, a case of MMBT in a 22 years old woman was experienced at our department. We presented this case with a brief review of literature.

BACKGROUND: The wound healing process is impaired or delayed in aged patients. The development of a new wound healing model is needed. Nerve growth factor (NGF) plays a special role in wound healing because NGF is expressed only in proliferating tissues such as wounds. OBJECTIVE: The aim of our study was to develop a wound healing model using a 3-dimensional culture system, raft culture, by comparing the level of NGF expression according to the wound stage after an artificial wound was made to the raft samples. We tried to specifically localize the site of NGF expression both in mRNA and protein level. METHODS: Raft culture using normal human keratinocytes was done and a 2 mm slit wound was made in the center of the raft samples. Raft samples of no wound, 4 d, 7 d, and 9 d after wounding were prepared. In situ RT-PCR and immunohistochemistry were performed to detect and localize NGF expression after making wounds and the addition of substance P (SP). RESULTS: We failed to localize NGF mRNA expression in raft samples by in situ RT-PCR. Immunohistochemistry showed NGF staining throughout the epidermis although a little more dense staining was found in the basal layer. NGF(+) cells tended to increase until 7 d after wounding, but there were no significant differences according to the wounding days. There was `a tendency that the SP(+) group showed more NGF(+) cells than the SP(-) group, but there were no statistical differences. CONCLUSION: We think that our in vitro raft wound model using NGF expression could be used, at least in part, as an objective indicator for wound healing. In our raft model lacking nerve, NGF may not be suitable for representing wound healing process because this model can not reflect the interaction between the skin and the nervous system. Expression of growth factors or cytokines other than NGF need to be applied to our raft culture system.

BACKGROUND: Gamma linoleic acid (GLA, Epogam) is considered a safe and effective modality in the treatment of atopic dermatitis (AD) in which impaired function of the enzyme, delta-6-desaturase, has been reported to result in reduced levels of GLA, desaturated fatty acids. OBJECTIVE: We performed this study to observe the changes of skin surface conditions measured objectively by bioengineering methods in relation to clinical improvement after treatment with GLA (Epogam®) in children with AD. METHODS: Thirty-four children with AD were treated with GLA (Epogam®) and evaluated with clinical parameters.The changes of skin surface conditions were monitored by non-invasive experimental instruments. RESULTS: There was a significant decrease of transepidermal water loss (TEWL) and gradual improvements in clinical severity after 12 weeks of GLA (Epogam®) treatment. The change of skin surface pH was statistically significant on the antecubital fossa and abdomen except the popliteal fossa. The other parameters including skin surface hydration and skin surface lipid did not show consistent changes. CONCLUSION: Clinical improvement of AD with GLA (Epogam) seemed to be achieved by the reduction of TEWL.

Constrictive pericarditis is caused by fibrosis of the pericardium leading to decrease in ventricular compliance. The diagnosis is often delayed due to nonspecific signs and symptoms. The authors experienced eight cases of constrictive pericarditis detected on chest CT scan while being treated for considerable length of time under the clinical impressions of intrathoracic tumor, tuberculous pleural effusion, liver cirrhosis, etc. Constrictive hemodynamics of these patients were confirmed by echocardiogram and cardiac catheterization. Among them five cases were due to tuberculosis. In four cases with pathologically proven tuberculous granuloma, the pericardium was markedly thickened and intensely enhanced. Associated pericardial effusion (n=3), and mediastinal lymphadenitis (n=3) were present, but pericardial calcifications were not seen. On the other hand, the fibrosis group (n=3) displayed mild pericardial thickening. All the three patients showed pericardial calcifications, mild or absent enhancement of pericardium, but no mediastinal lymphadenitis. The cardiovascular changes such as inferior or superior vena caval distension, left ventricular deformity, interventricular septum angulation, and biatrial enlargements were more severe than those in patients with active granuloma. In patients with constrictive pericarditis with nonspecific signs and symptoms, CT scan is very helpful in making the diagnosis and can give informations about the evolution of the disease.

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: To quantify the cardiac dose reduction during breathing adapted radiotherapy using Real-time Position Management (RPM) system in the treatment of left-sided breast cancer. MATERIALS AND METHODS: Twenty-two patients with left-sided breast cancer underwent CT scans during breathing maneuvers including free breathing (FB), deep inspiration breath-hold (DIBH), and end inspiration breath-hold (EIBH). The RPM system was used to monitor respiratory motion, and the in-house self respiration monitoring (SRM) system was used for visual feedback. For each scan, treatment plans were generated and dosimetric parameters from DIBH and EIBH plans were compared to those of FB plans. RESULTS: All patients completed CT scans with different breathing maneuvers. When compared with FB plans, DIBH plans demonstrated significant reductions in irradiated heart volume and the heart V25, with the relative reduction of 71% and 70%, respectively (p < 0.001). EIBH plans also resulted in significantly smaller irradiated heart volume and lower heart V25 than FB plans, with the relative reduction of 39% and 37%, respectively (p = 0.002). Despite of significant expansion of lung volume using inspiration breath-hold, there were no significant differences in left lung V25 among the three plans. CONCLUSION: In comparison with FB, both DIBH and EIBH plans demonstrated a significant reduction of radiation dose to the heart. In the training course, SRM system was useful and effective in terms of positional reproducibility and patient compliance.
