Abstract: Pure sarcomas of the esophagus are exceedingly rare. We report a case of esophageal synovial sarcoma which occurred in an adolescent. The tumor was locally resected, sparing the patient esophagectomy. After postoperative radiation therapy, the patient remains alive and well without evidence of disease 28 mo after operation. The unique nature of polypoid sarcoma of the esophagus, and the potential for cure without esophagectomy, is discussed.

Abstract: Presented is the ninth reported case of teratocarcinoma arising from the parenchyma of the lung. Treatment should include wide surgical resection and adjuvant chemotherapy. Postoperative radiation therapy should be utilized if there is residual disease or nodal metastasis. Preoperative radiation therapy should be considered if there is evidence of chest wall involvement.

Abstract: Macroporous polystyrene and polyvinylpyridine beads with quaternary ammonium and tertiary groups were tailor-made for the adsorption of unconjugated bilirubin. In vitro studies in order to obtain high adsorption capacity, the synthesized macroporous resin should have an average pore size of about 160 A and with surface area as large as possible. As the crosslinking of the resin increased from 4%-40% the amount of bilirubin adsorbed increased from 0.17 mg/g to 2.0 mg/g. Resins containing strong basic groups have higher adsorption capacities than their corresponding weak base groups. Adsorption mechanism studies showed that both chemical and physical adsorption took place. Adsorption of bilirubin in plasma was some what lower than in buffer solution.
