BACKGROUND: Exercise is a very common precipitant of asthma. Broncho-constriction associated with exercise can occur in 75~90% of individuals with asthma. The estimated prevalence ( 30~85% ) of gastroesophageal reflux ( GER ) in patients with asthma is significantly higher than in general population. We performed pH monitoring during the exercise in order to evalute whetherexercise induced asthma EIA ( 6 men, 12 women ) were studied. Monitoring of intraesophageal pH, ECG and spirometry was done for 1 hour before treadmill exercise. After baseline monitoring, subjects underwent symptom-limited treadmill exercise with Bruce protocol and continuous monitoring for 60 min after exercise. Spirometry was done at baseline prior to exercise, and repeated every 10 min after full exercise for 60 min. RESULTS: Exercise-induced bronchoconstriction was noted in 15 patients, who performed MBPT and 12 patients confirmed for bronchial asthma and 3 patients were diagnosed exercise-induced astham. Five 15 EIA patients demonstrated a pathologic degree of GER. CONCLUSION: We suggest that GER may be one of pathophysiologic factors of ELA and evoke further concentration on the GER in the EIA patients.

BACKGROUND: Sustained-release theophylline, which is generally prescribed as a twice-daily equal-dose regimen, is one of the more common asthma treatments. the development of a sustained-release drug delivery technology that enables improved control of the theophylline blood levels represents a significant advancement in both the efficacy and safety of dosing. METHOD: A crossover study was conducted with 25 adult chronic asthmatic patients requiring daily bronchodilator therapy. The study group included thirteen males and twelve females with ages ranging from 19 to 71 years. The overall approach was to place the patients first on the twice-daily preparation(Etheophyl®) for 28 days at 8 AM and 8 PM, and measure the pulmonary function and theophylline level on the 28th day. the patients were subsequently switched to the once-daily preparation(Uniphyl®) in the same daily dose at 8 PM on the 29th day and the same parameters were measured on the 56th day. RESULTS: the mean serum levels of theophylline were 8.18±1.66µg/ml in the Etheophyl®-treated period and 8.00±1.75µg/ml in the Uniphyl®-treated period. In addition, the FEV1 showed 71.40±7.48 percent in the Etheophyl®-treated and 69.18±9.00 percent in the Uniphyl®-treated period. Thus there were no significant differences between the once-daily and twice-daily preparation. CONCLUSION: The results indicated little clinical differences between the two medication. The two drugs are equally effective in controlling asthma over the four weeks of treatment.

The present study was undertaken to observe the quality and quantity of lipid constituents by the developing Ascaris suum eggs. The collected eggs from the uterus of A. suum were classified into 3 groups, i.e., single cell stage, morula stage and embryonated eggs, and were subjected to analyse their lipid fractions. To obtain the morula stage eggs, 10 to 11 incubation days at 30 degree C were needed and for the embryonated eggs, 30 to 31 days were lasted. At the time of experiment, their indices of development by Hoffman were 285(morula stage) and 42 (embryonated stage) respectively. Lipid extraction was done by the methods of Folch et a1. (1957) and Kenny (1952), and then the extracted lipid fractions from the above 3 groups of eggs were separated by thin layer chromatography. Those fractions were also subjected to perform the quantitative analyses of fatty acids, glycerides, cholesterol and phospholipids. The results obtained were summarized as follows. Total amount of fatty acid was decreased from 12.9 mg per gram of eggs (single cell stage) to 6.6 mg/gm (embryonated eggs), whereas the proportion of free fatty acid to total fatty acid was constantly increased from 77.5 percent to 89.4 percent during the period of egg development. Total amount of glycerides was also increased from 33.0 mg/gm of single cell stage to 55.9 mg/gm of the embryonated eggs. The most abundant glyceride among 3 glycerides discovered from A. suum eggs was triglyceride, and the least was monoglyceride. The amount of free cholesterol was much larger than that of ester form in general, and it reached maximum in the eggs of morula stage (4.6 mg/gm). The increase of total cholesterol was monitored during the development of A. suum eggs from 3.3 mg/gm to 5.4 mg/gm. The following 8 phospholipids were detected in the embryonated eggs, i.e., lysophosphatidyl choline, phosphatidyl inositol, sphingomyelin, phosphatidyl choline, phosphatidyl glycerol, phosphatidyl serine, phosphatidyl ethanolamine and unknown phospholipid. But in the single cell stage eggs, 4 kinds out of the above 8 phopholipids were not observed, and in the morula stage eggs, 2 kinds were absent among the 8 phospholipids.

In attempt to investigate histone fractions and non-histones of parasites, nuclei were isolated from Fasciola hepatica by the procedure of Pogo et al. (1966). Histone fractions H1, H2a, H2b, H3 and H4 were prepared from isolated nuclei by the procedure of Johns (1964 and l967). The five histone fractions found in most tissues were also present in the Fasciola hepatica histones. These histone fractions were characterized by amino acid analysis and by polyacrylamide disc gel electrophoresis. Non-histone proteins were extracted from isolated Fasciola hepatica nuclei and separated by SDS-polyacrylamide gel electrophoresis. The results of the experiment were summarized as follows: The yield of whole histone recovered was 2.47 mg per 1 g of Fasciola hepatica. The yield of DNA was 1.02 mg per gm of tissues. Consequently the DNA to histone ratio was 1:2.44. The relative amounts of five fractions, i.e., Hl, H2a, H2b, H3 and H4 were 19.96 percent, 26.48 percent, 29.60 percent, 12.56 percent and 14.37 percent, respectively. Amino acid analysis of the individual histone fractions showed that the over-all compositions were similar but not identical to those of corresponding fraction from calf thymus. It was found that histone H2b fraction of Fasciola hepatica contained detectable amounts of epsilon-N-monomethyllysine. No evidence for the presence of methylated lysine or other side-chain derivatives was reported on this histone fraction. In SDS-polyacrylamide disc gel, it showed that 17 protein bands of nuclear acidic protein can be identified visually.

BACKGROUND: Interleukin-4(IL-4) from the Th2 subset of lymphocytes has been known to have a key role in the pathogenesis of atopic dermatitis. Blood levels of IgE, often reflecting the severity of allergic diseases, are not always elevated in patients with atopic dermatitis due to its homocytotrophic characteristics. OBJECTIVE: We propose that IL-4 can substitute or at least complement the role of IgE as an index of disease severity of atopic dermatitis. METHODS: Eleven patients with atopic dermatitis and five normal controls were included in this study. Before treatment, we evaluated the clinical severity of atopic dermatitis by the method described elsewhere with some modification which employed extent, duration, and intensity of skin lesions. Based on this criteria, we divided patients into 'severe and mild groups. With blood samples drawn from patients and normal controls, we measured IL-4 and IgE values. After a treatment period of I to 2 months, when all of the patients became free of symptoms and signs of atopic dermatitis, patients in each group were re-evaluated for ehanges of IL-4 and IgE values. IL-4 values were determined with a Predicata human interleukin-4 kit from Genzyme diagnostics (Predicta IL-4 kit) and ELISA reader (CRES UV900, Biotek). IgE values were measured .with IMx total IgE assay system from Abott laboratories (model 8389-0). RESULTS: l. Of eleven patients, six were mild and five were severe in clinical severity. 2. IL-4 levels were decreased from the pre-treatment average value of 57.149+/- 40.079 pg/ml to a post-treatment average value of 32.072+/- 16.912 pg/ml (p<0.05) which was similar to average normal control value, 36.690+/- 24.451 pg/ml. 3. IgE levels were similarly decreased from an average value of 230.2 86.4 IU/ml before treatment to one of 171.S+/-79.4 IU/ml after treatment (p<0.05). 4. This tendency of post-treatment lowering of values became more apparent in severe groups (p<0.05) but less obvious in mild groups both in terms of IL-4 and IgE (p>0.1). CONCLUSION: We conclude that IL-4 is not only involved in the pathogenesis but can also be used as a main index of disease severity in atopic dermatitis especially when the clinical severity is more than mild.
