To evaluate the effects of fog on asthmatics, we analyzed the symptoms of a 45-year-old female during the foggy season and the relation between diurnal peak expiratory flow rate (PEFR) and fog and other meteorological factors. Her asthma attacks had been induced by specific smells: perfume, smoke from burning grass or industrial smoke. Two years previously, she had moved to the suburbs of Sapporo, where fog frequently occurs. From that time her asthmatic symptoms had been exacerbated, so it was suspected that the fog might have had some influence. We analyzed 251 measurements of PEFR from June to August 1994. The average and standard deviation of PEFR in the absence of fog and specific smells was 403 ± 40 L/min (n=195). PEFR was significantly lower (p<0.01) when it was foggy (347 ± 60 L/min; n=40), when specific smells were present (333 ± 60 L/min; n=5) and when there were both fog and specific smells (340 ± 53 L/min: n=11). On the other hand, there were no changes associated with other meteorological factors: barometric pressures, relative humidity, mean temperature, minimal temperature and most frequent wind direction. These results suggested that the inhalation of fog decreases PEFR and is an exacerbating factor in bronchial asthma.

In our Department, continuous isoproterenol inhalation therapy has been conducted on status asthmatics over the last 10 years. In the present study, we investigated whether there are any differences in the therapeutic efficacy of continuous inhalation of isoproterenol in the presence or absence of respiratory infections which may induce or aggravate asthma attacks. The treatment period was significantly longer in patients with pneumonia. Further prolongation of the treatment period was noted in patients with atelectasis. However, there were no apparent differences in therapeutic efficacy according to age or the severity of attacks. These findings suggest that continuous inhalation of isoproterenol is very effective for status asthmatics if respiratory infections are thoroughly controlled.

In asthmatic children without he egg allergy, spontaneous IgE production of PBMC showed 1.27 ± 0.28 IU/ml (Mean ± SE) and IgE production of Dermatophagoides farinae (Df) stimulated PBMC after which IFN-γ decreased to 0.89 ± 0.23 IU/ml (Mean ± SE) (p<0.001). IgE production of Ovalbumin (OVA) stimulated PBMC after which IFN-γ showed no decrease. In asthmatic children with hen egg allergy, IgE production of OVA stimulated PBMC and IFN-γ decreased to 1.0 ± 0.52 IU/ml (Mean ± SE). In spontaneous IgE production it was 1.61 ± 0.91 IU/ml. (p<0.05). IL-4mRNA was expressed in spontaneous PBMC in asthmatic children, but not in healthy non atopic children. The expression of IL-4 mRNA was suppressed in Df stimulated PBMC followed by IFN-7 in as thmatic children. In asthmatic children, IFN-γ mRNA were expressed in Df stimulated PBMC after which IFN-γ. And simultaneously IgE production in Df stimulated PBMC were suppressed by addition of IFN-γ.

We investigated factors relating to mercury sensitization in 156 medical students (mean age 22.7 ± 2.4, mean ± S.D., male 113, female 43). Their allergic symptoms, lifestyles and family histories were studied by questionnaire. Patch tests were performed on them with HgCl_2 (0.05%aq.), NiSO_4 (5%aq.), PPD (2%pet.) and urushiol (0.01%pet.). Anti-dermatophagoides and anti-cryptomeria pollen IgE antibodies in serum were also measured. While the positive rates of urushiol, nickel and PPD were 11.1%, 5.1% and 2.6%, respectively, that of mercury was as high as 12.8%. Each allergen specific antibody positivity and past histories of allergic diseases were not associated with mercury sensitization (by the chi-square test). Mercury sensitized students had significantly more frequently experienced eczema caused by cosmetics, shampoos, soaps and haircreams (by the chi-square test, p<0.005). They also had significantly more teeth treated with metals compared to the controls (one-tailed t-test, p<0.05). And their urinary mercury concentrations were significantly higher than those of the controls (one-tailed t-test, p<0.05). These findings suggest that mercury sensitization is associated with exposure to mercury in the living environment.

Bronchial asthma is characterized as a chronic inflammation of the airway that causes an infiltration of lymphocytes and eosinophils. Cell to cell interaction or cell to tissue interaction is essential for infiltration of eosinophils to underlying tissues. These phenomena are closely related to the expression of intercellular adhesion molecule-1 (ICAM-1). Inhalation of steroids, such as beclomethasone dipropionate, is commonly used to cure airway inflammation. In this study, we investigated the effect of cytokines on ICAM-1 expression on human bronchial epithelial cell lines, NCI-H_<292>. Moreover, the effect of dexamethasone on ICAM-1 expression stimulated by IL-1β, TNF-α and IFN-γ was observed. Treatment with IL-1β, TNF-α and IFN-γ dose-dependently increased ICAM-1 expression on NCI-H_<292> cells. Inhibitory effects were exerted by dexamethasone on ICAM-1 expression in cells stimulated by IL-1β and IFN-γ in a dose-dependent manner, but not in cells stimulated by TNF-α. These results suggest that the inhibition of ICAM-1 expression could be related to the pharmacological action of steroid drugs.
