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.

BACKGROUND AND OBJECTIVES: Ischemic preconditioning (IP) has been shown to reduce the infarct size and severity of arrhythmia in a post-ischemic reperfused heart. Angina before myocardial infarction reflects brief episodes of myocardial ischemia and may be a marker of ischemic preconditioning. We studied the effect of a history of previous angina on early outcomes (infarct size, left ventricular (LV) function and residual myocardial ischemia) for patients with acute myocardial infarction (AMI) after thrombolytic therapy. MATERIALS AND METHOD: We examined prospectively 58 consecutive patients who had AMI and arrived hospital within 6 hours after chest pain developed. IP was defined as prodromal angina within 24 hours before myocardial infarction. Patients were divided 2 groups:Group I (Gr I, 30 cases) without IP, Group II (Gr II, 28 cases) with IP. Thrombolytic therapy was done 23 cases (77%) and 21 cases (75%) respectively in each groups. Thereafter, electrocardiographic findings, infarct size on the basis of peak creatine kinase, LV function on the 2-D echocardiographic findings, recurrent myocardial ischemia were examined between 2 groups. RESULTS: In predischarge 2-D echocardio-graphic findings, LV dilatation and normal regional wall motion did not differ between two groups. But, there were significantly smaller creatine kinase (CK)-determined infarct size in Gr II than that in Gr I (peak CK level, Gr I:1566.3+/-960.0 IU/L vs Gr II:1066.9+/-773.2; p<0.05). The time interval between the onset of infarction and peak CK level was shorter in Gr II than that in Gr I (Gr I:18.3+/-8.3 vs Gr II:10.7+/-3.4 hours; p<0.001). There were significantly more common incidences of residual myocardial ischemia in Gr II (Gr I:26.7% vs Gr II:60.7%; p<0.01). CONCLUSION: Patients with a history of prodromal angina preceding myocardial infarction had small infarct size and earlier reperfusion of infarct related artery. However, there were significantly more common residual myocardial ischemia in these patients and a trend toward re-infarction on same previous infarction sites.

BACKGROUND: The aim of this study was to compare the efficacy of ketorolac, paracetamol, and paracetamol plus morphine on pain relief after thyroidectomy. METHODS: Eighty patients were randomly allocated to one of the 4 groups: normal saline (group C), ketorolac 30 mg (group K), paracetamol 1 g (group P), and paracetamol 700 mg plus morphine 3 mg (group PM). Each regimen was administered intravenously (IV) 30 min. before the end of surgery. If pain was not relieved, patients received an IV bolus of pethidine hydrochloride 25 mg. Pain intensity using a visual analogue scale (VAS) was recorded at 0.5, 1, 2, 4, and 6 hr after the end of surgery. RESULTS: VAS at 0.5 and 1 hr after the end of surgery were significantly lower in group K, group P, and group PM than in group C (P < 0.05). The number of patients receiving pethidine hydrochloride at 0.5 and 1 hr after the end of surgery was significantly lower in group K, group P, and group PM than in group C (P < 0.05). There was no significant difference among the groups in the incidences of adverse events associated with study medications and patient satisfaction (P > 0.05). CONCLUSIONS: Paracetamol 1 g IV possesses a similar analgesic efficacy to ketorolac 30 mg IV after thyroidectomy. Paracetamol may represent an alternative to ketorolac for pain prevention after mildly to moderately painful surgery in situations where the use of NSAIDs is unsuitable.

BACKGROUND: Cockroaches are important components of house dust allergens. In spite of significant subject reactivity to cockroach extracts, the specific source of the allergen remains unclear. OBJECTIVE: This study was performed to identify the important allergens in German cockroach whole body (GWBE), egg (GEE) and fecal (GFE) extracts in Korean atopy, and to compare the reactivity of GWBE and GEE by Western blot inhibition. METHODS: Sera from 11 subjects with Korean atopy were used for sodium dodecil sulfate polyacrylamide gel elctrophoresis (SDS-PAGE) and Western blot analysis. RESULTS: Allergenic fractions in German cockroach extracts were numerous and distributed throughout the wide range of molecular weights. The important allergens of GWBE, GFE and GEE were similar to each other by using SDS-PAGE and Western blot ysis. The aUergen bands at 55 kd showed the most significant reactivity; in GWBE, GFE and GEE 73%, 82%, 55%, respectively. Other bands exhibiting significant activity were the 67 kd band with 37%, 19% and 19%, the 64 kd band with 64%, 37% and 9% respectively. Furthermore, Western blot inhibition investigations revealed that either GWBE or GEE could almost completely inhibit the reactivity of the other extract. CONCLUSION: This study confirms that the 55 kd allergen can be considered as the major allergen in Korean atopy and demonstrated that the GWBE and GEE antigens have identical IgE-binding sites.

BACKGROUND: Atopic dermatitis (AD) is primarily influenced by environmental factors including exposure to pollutants and indoor allergens (particularly, house dust mites). Al-though house dust mite antigens are the most prevalent components of indoor allergens in Korea, cockroaches also can be considered to act as an important allergen. OBJECT: This study was done to evaluate the differences in three different atopic patch test (APT) techniques, and the relationship between APT and skin prick test, total IgE, and specific serum IgE level using cockroach allergen. Methods: We performed patch test in 57 patients with AD and 30 normal controls on clinically lesional and normal appearing skin with German cockroach (GC) allergens (extract, as is) in three different techniques (standard, scratch, DMSO). Reactions were evaluated after 48hours, and compared with the results of skin prick test, total and specific IgE levels. Detailed atopy history and severity scoring were taken. RESULTS: In the GC (whole body) prick test positive group, there was 1263.02 IU/ml of total IgE, and this amount was significantly higher than GC (whole body) prick test negative group who had 549.46 IU/ml (P<0.05). The positive reaction rate to whole body of American cock-roach (AC) was significantly higher in the patient group than control group (p<0.05), but the positive rate to whole body of GC was high, but not significantly high in the patient group (p=0.053). There were significant differences in positive patch test reactions to either Ext or As is between patient group and control group (p<0.05). The positive rate to As is was significantly higher than to Ext in either lesional skin or non-lesional skin in patient group (p<0.05). But there were no considerable differences in positive reactions to either Ext or As is between 3 different methods (standard, scratch, DMSO mix) in both lesional and non-lesional areas (p>0.05). There was no significant relationship between the positive reactions to patch test and prick test to Ext and As is antigen. The APT results showed no significant concordances with skin prick test and RAST for cockroach antigens. CONCLUSIONS: APT seems to be a different dimension of atopic skin inflammation and may pro-vide further diagnostic information in addition to a patient's history, skin prick test, and RAST results.
