A comparative study of the incidence of indoor and outdoor mold spores in Bangkok, Thailand.

The culture plate method was used in this survey of the indoor and outdoor incidence of the atmospheric molds in Bangkok Metropolis in the year 1977. The over-all sampling showed the prevalence of yeasts, Aspergillus, Hermodendrum and non-sporulated white fungi as the frequency of occurrence; each of them was over 50%. In general the incidence was high in the winter months and low in the rainy season except for Aspergillus, Fusarium and Curvularia which did not decline during the rainy period. Observations indicated that there are only slight differences between the incidence and the types of airborne fungi recovered from the exposed plates in the bedrooms and outside the houses in and around Bangkok Metropolis.

Intranasal inhalation of beclomethasone dipropionate in the treatment of perennial rhinitis in adults.

Forty-eight perennial rhinitis patients completed a six weeks' open trial of intranasal beclomethasone dipropionate aerosol. Each received a daily dose of 400 micrograms. Thirty-five responded excellently, seven reported satisfactory improvement and six failed. This study indicated that patients with a demonstrable allergic component responded favorably. However, due to the wide margin of safety the authors suggest that it be tried on the non-infective perennial rhinitis with no demonstrable allergic component as well.

Demonstration of dengue antibody complexes on the surface of platelets from patients with dengue hemorrhagic fever.

By the direct immunofluorescent technic, dengue antigen, human immunoglobulins, and beta 1C globulin were detectable on the surfaces of platelet suspensions from 48% of patients with dengue hemorrhagic fever. The percentages of positive-staining platelets were not related to the severity of thrombocytopenia, which was marked on the day after the patient developed shock or subsidence of fever. It is suggested that an immunologic mechanism is one of the factors associated with the thrombocytopenia caused by increased platelet destruction.

The defined antigen substrate sphere system with direct immunohistoperoxidase for detection of soluble dengue antigen in sera of patients with dengue hemorrhagic fever.

The defined antigen substrate sphere system is a simple method for detecting antigen or antibody in the circulation. The technic is based on the coupling of antigen or antibody with Sepharose 4B beads that have been activated by cyanogen bromide. In this study the activated beads were exposed to dengue antigen in the serum from a patient with dengue hemorrhagic fever and then stained with antidengue antibody conjugated with horseradish peroxidase. The positive reaction showed brown beads by light microscopy, whereas the negative reaction gave colorless beads. The authors examined 134 specimens from 91 cases. The results were positive in 53.85%. The dengue antigen appeared in the sera on the day before shock or subsidence of fever. The percentages of sera containing soluble dengue antigen were greatest on the day of shock or subsidence of fever (33.33%) and on the fifth day of fever (28.07%). The highest titers of soluble dengue antigen (1:40 to 1:80) appeared in the sera of patients who had Grade III disease on the day of shock. The dengue antigen appeared most often in sera that had high titers of dengue antibody. It is postulated that this detected dengue antigen may be a part of soluble immune complexes formed during the hyperimmune stage of the immune response, and plays a significant role in the pathogenesis of dengue hemorrhagic fever and shock syndrome.
