Neurilemmomas are benign nerve sheath tumors derived from Schwann cells that rarely occur in the chest wall. Neurilemmomas of the chest wall are usually solitary lesions that bulge toward the pleural cavity. Neurilemmomas are confirmed histologically based on the presence of Verocay bodies, Antoni A and Antoni B tissue patterns and S-100 protein. Bilateral neurilemmomas in the chest wall are extremely rare, as are those that grow in the subcutaneous tissue but not the pleural area. We report here a case of bilateral chest wall neurilemmomas in which the tumors bulged out to the skin and were palpable. (Tuberc Respir Dis 2008;65:318-322)

Anion adsorption properties of organobentonites modified by two cationic polymers, hexadecyltrimmethylammonium (HDTMA) and cetylpyridinum (CP), were investigated. The organobentonites showed the significant expansion of basal spacing to 42.0 Å at room temperature. The adsorption experiments were conducted for the 0.2 g of organobentonites with 40 mL solutions of various concentrations of anions such as nitrate, sulfate and phosphate. As a result, the organobentonites showed excellent adsorption capacities for those anions whereas untreated bentonite showed very low adsorption capacity. Adsorption rate of HDTMA-bentonite was about 90% for 100
