Esophagopericardial fistala is a rare and usually life threatening complication of both benign and malignant esophageal disease. A case of pyopneumopericarduim in 45 year-old female is reported. Streptocoeeus viridana in pas celtore was isolated from pericardial pus. The disorder resulted from eaqyhagoyericardial fistula which probably developed as a complication of esophageal diverticnlum. The diagnasis of the fistula was established preoperatively on the basis of chest X-ray, esophagogram and. endoeeopic findings. The treatment was thoracotorny with drainage of pericardium, diverticulectomy and antimicrobial chemotherapy. The patieat improved postoperatively.

Extensive column chromatography separation of the MeOH extract from the aerial parts of Phyllanthus urinaria afforded seventeen compounds (1 - 17). The structures of the compounds were elucidated by physicochemical and spectroscopic methods to be 5′-β-D-glucopyranosyloxyjasmonic butyl ester (1), (+)-cucurbic acid (2), dendranthemoside B (3), boscialin 4′-O-β-D-glucoside (4), 4,5-dihydroblumenol A (5), (6R,9R)-megastigman-4-ene-9,13-diol (6), (3S,5R,6S,9R)-3,6-dihydroxy-5,6-dihydro-β-ionol (7), (6S,9R)-roseoside (8), mallophenol B (9), icariside B 5 (10), corchoinoside B (11), canangaionoside (12), 5,6-epoxy-3-hydroxy-7-megastigmen-9-one (13), icariside B 2 (14), (7E)-2β,3β-dihydroxy-megastigm-7-en-9-one (15), betulalbuside A (16), and loliolide (17). The compounds 1, and 3 - 16 were isolated for the first time from this plant. The absolute stereochemistry of compound 1 was newly determined. The isolated compounds were tested for cytotoxic activity against four human tumor cell lines in vitro using a Sulforhodamin B bioassay, but all the compounds showed weak cytotoxic activities.
