OBJECTIVE: The aim of this study was to investigate the usefulness of serum ECP as a marker of the severity of asthma and extent of airway inflammation. METHOD: We investigated 108 patients suffering from bronchial asthma, who were classified as mild intermittent(n=19), mild persistent(n=27), moderate persistent(n=42), and severe persistent(n=20) and 10 healthy controls. Atopy was defined as those who showed >2+ responses on skin prick test. Serum ECP, peripheral blood eosinophil, sputum eosinophil, and PEFR were measured on the same date and meth~acholine PC20 were determined within 2 weeks. RESULTS: Serum ECP levels were 10.1+- 2.0 ug/L in controls, and 29.1+- 23.6 ug/L in asthmatic patients. According to symptom severity, serum ECP levels were 22.9 +- 15.6 ug/L, 28. 6 +- 24.1 ug/L, 29.5 +- 22.2 ug/L, and 34.6 +- 31.2 ug/L in mild intermittent, mild persistent, moderate persistent and severe persistent asthmatic patients, respectively and there were no significant differences among four groups(p>0.05). Serum ECP levels correlated with peripheral blood eosinophil counts(r=0.48, p<0.01), but not with sputum eosinophil, PEFR, and methacholine PC20 levels. There was no significant difference in serum ECP level between atopic and non-atopic asthma(p>0.05). CONCLUSION: Single measurevment of ECP level at clinic could not represent the severity of asthma.

Heterogeneity in clinical features and pathogenesis of non-steroidal anti-inflammatory agent (NSAIDs) hypersensitivity have been reported. NSAIDs can cause bronchial constriction in asthmatics or hives and angioedema in patients with chronic urticaria, in which case causative drugs show cross-reactivity with other NSAIDs. Normal subjects without allergic diseases may develop urticaria angioedema or anaphylaxis after ingestion of a specific NSAID. In this type of reaction, cross-reactivity between causative drugs and other NSAIDs does not occur. We experienced a case of acetaminophen anaphylaxis without aspirin sensitivity in a 38-year-old male, which was confirmed by oral provocation test. An oral challenge with 150mg of acetaminophen induced urticaria in lower legs, and erythema, with febrile sensation in ears. With a dose of 600mg acetaminophen, urticaria developed in trunk and extremities with facial angioedema. An oral provocation test with 650mg of aspirin was well tolerated without any adverse reactions. We report acase of acetaminophen anaphylaxis, which occurred in a normal individual at a small dose(150mg) without cross-reactivity with aspirin. This type of reaction supports heterogenei~ty of NSAIDs hypersensitivity and it may be caused by an other mechanism, not by cyclooxygenase inhibition.

From January to December 1984, 191 patients with associated ventricular septal defect(VSD) were studied in the cardiac cathetherization laboratory. Among theses 191 cases, 58 cases(30.4%) of subpulmonic VSD were identified by angiocardiography. Among the 59 cases of subpulmonic VSD, 12 cases(20.6%) were complicated with aortic infficiency(AI). The relative frequency of subpulmonic VSD increased with the increase of age and the frequency of complication of AI with the subpulmonic VSD also increased with the increase of age. The amount of left to right shunt in the patients with subpulmonic VSD and AI was small and Qp/Qs ratio was less than 2.0 in all of the 12 cases. Among the 12 patients 4 cases had a pressure gradient greater than 20 mmHg across the infundibular region of the right ventricle.

Background:
Erythropoietin (EPO), which is associated with anemia, exerts neuroprotective effects in ischemic stroke. In cases of stenosis or narrowing of the main cerebral blood vessel, the prognosis is favorable if collateral blood circulation is well developed in acute stroke. Several studies have investigated the relationship between EPO administration and stroke outcomes. The present study investigated the correlation between serum EPO level and cerebral collateral circulation, which could result in favorable clinical outcomes.
Methods:
The study subjects were patients diagnosed with acute ischemic stroke who underwent initial brain magnetic resonance imaging between January 2020 and March 2022. Following brain computed tomography perfusion for collateral flow, serum EPO levels were measured. Collaterals were assessed according to the Mass system and divided into good collateral (GC) or poor collateral (PC) groups. Serum EPO levels were determined using a chemiluminescence immunoassay method. A correlation coefficient analysis was conducted to determine the correlation between serum EPO levels and GC. A receiver operating characteristic curve analysis determined the cutoff value of EPO for GC.
Results:
Serum EPO levels were significantly higher in the GC than that in the PC group (P<0.05). The cut-off level of serum EPO for a good outcome was 9.1 mIU/mL.
Conclusion
A high serum EPO (>9.1 mIU/mL) could be a marker of GC in patients with acute ischemic stroke that predicts good clinical outcomes.

BACKGROUND: renal artery stenosis (RAS) is a major cause of renovascular hypertension and renal function due to ischemic atrophy of kidney. There are several methods to treat the RAS, including are surgery, percutaneous transluminal renal angioplasty, and medical treatment. The purpose of this study is to evaluate the usefulness, safety, and efficacy of percutaneous transluminal stent deployment in RAS. METHOD: From January 1995 to July 1996, 17 patients underwent renal stent implantation due to renal artery stenosis (11 male, 6 female). the mean age was 49 years old, one patient had both renal artery stenosis and total lesions were 18. The causes of renal artery stenosis were atherosclerosis in 12, fibromuscular dysplasia in 2, Takayasu's disease in 2, and autoimmune disease (Bechet's) in one case. Renal artery stenting was performed via femoral artery in 12 lesions and brachial artery in 6 lesions. Follow up was performed by renogram, renal angiogram, and clinical examination. RESULT: the degree of renal artery stenosis was 83% (70-95%). the lesion sites were 12 ostial and 6 non-ostial lesions. The used renal stents were Palmaz-biliary stent in 17 lesions and Micro-2 stent in one lesions. All stents were implanted successfully and there was no residual stenosis in all patients except one case showed 20% residual stenosis due to huge renal artery size. The transstenotic pressure gradients after renal artery stenting was decreased markedly from 74mmHg to 2mmHg. There no serious complications such as a death, emergency surgery, or nephrectomy. There were two minor complications which were one case of pyelonephritis and one case of inguinal hematoma. After stenting, blood pressure was decreased partially in 13 patients and completely in 2 cases. CONCLUSION: Renal artery stenting appears to be safe and feasible and the alternative treatment modality to surgery for renal artery stenosis.

Objective : The aim of this study was to evaluate cross - reactivity between pollens in patients with strong skin reactivity to multiple pollens. METHODS: A pool of sera from 20 patients who showed strong skin responses( > or = 3+ ) to all three kinds of pollens ( tree, grass, and weed ) was used. Oak, ryegrass, mugwort, ragweed and hop Japanese pollens were chosen for the subject of study. The level and pattern of bound IgE to each pollen and cross - reactivity between pollens were investigated by ELISA and immunoblot experiments. RESULTS: In ELISA, the IgE of a pool of sera reacted to ryegrass and ragweed in 100%, to mugwort in 95%, to oak in 75%, and to hop Japanese in 65%, respectively. In inhibitory ELI - SA, more than 50% of bound IgE was mutually inhibited in oak vs ryegrass, oak vs mugwort, mugwort vs ryegrass and mugwort vs hop Japanese. In immunoblot, the IgE binding rate to major allergens of each pollen was 95% for hop Japanese, 75% for ragweed, 50% for ryegrass, 35% for mugwort, and 30% for oak, respectively. In inhibitory immunoblot, the mutually inhibited bound IgE could not be observed between major allergens of each pollen, but some minor allergens of oak pollen were mutually inhibited by ryegrass. CONCLUSION: Cross - reactivity between major allergens of oak, ryegrass, mugwort, ragweed and hop Japanese pollens was not observed at all, but some minor allergens of oak pollen cross-reacted with ryegrass and mugwort, and so did those of mugwort pollen with ryegrass and hop Japanese.
