In spite of low energy requirement, and operation and construction cost, biofilters with soil beds have not been operated efficiently. Because of excess moisture in winter and rainy periods, saturated pores in the bed prevent passage and sorption of odorous compounds. Sometimes this results in septic conditions that release previously sorbed and oxidized sulfur. Therefore, an economical and effective alternative needs to be developed. The objectives of this study were to confirm applicability of the granular scrap tires with compost for treating odorous gas as well as to obtain optimum design parameters for proposed system. In lab-scaled test, multiple stage reactors had lower headloss than a single stage reactor and less headloss was occurred for the gas with higher moisture content. For practical purpose, pilot-scaled reactor was operated to remove odor from septic tank, manure and animal wastewater treatment plant and composting machine. According to the results of pilot scaled test, $H_2S$ can be always removed completely and ammonia/amine can be removed excellently when proper moisture content is provided. The results from lab and pilot test showed that granular scrap tire could be replaced with soil as supporting material for biofilter showed excellent drainage because of its ability to reject moisture.

Several types of infection can cause organizing pneumonia when the inflammatory process remains active with the further organization of the intra-alveolar fibrinous exudates, despite the control of the infectious organism by antibiotics. We report a case of 37-year-old male with secondary organizing pneumonia associated with an endobronchial actinomycosis. The patient presented with a subacute cough, sputum and fever. Bronchial biopsy revealed sulfur granule to be consistent with the actinomycosis, and percutaneous needle biopsy revealed typical pattern of organizing pneumonia. The patient was treated with the appropriate antibiotics and corticosteroid. There was rapid improvement in the symptoms and radiological findings, and after six months of treatment, the corticosteroid dose was tapered off without a recurrence of the organizing pneumonia.

Actinomycosis is a bacterial infection that can affect virtually any site in the body. There are three major forms of actinomycosis: cervicofacial, abdominal, and thoracic. Aspergillus spp. are ubiquitous in the environment in most countries of the world. Pulmonary aspergillosis is clinically classified by aspergilloma, allergic bronchopulmonary aspergillosis and invasive aspergillosis. Actinomyces and Aspergillus, each of them was often reported in case, but mixed infection of both organisms have not been reported. We experienced a case of mixed infection of Actinomyces and Aspergillus involving the same area of the lung in a 62 year-old housewife presented with hemoptysis and solitary pulmonary nodule. Percutaneous needle aspiration and later surgical resection revealed sulfur granule mixed with Aspergillus hyphae in the same lesion. We report this case with a review of the literature.
