ABSTRACT
The first phytochemical investigation of the aerial parts of Bituminaria basaltica, an endemic species from the Aeolian Islands, led to the isolation and identification of eight compounds including plicatin B (3), two furanocoumarins: angelicin (1), psoralen (2), three pterocarpans: erybraedin C (4), 3,9-dihydroxy-4-isoprenyl-pterocarpan (5), bitucarpin A (8) and two flavonoid glycosides: isoorientin (6), daidzin (7). Their structures were elucidated by spectroscospic techniques and compared with data reported in the literature. Sesquiterpenes characterised the essential oil composition of the title plant where ß-caryophyllene and germacrene D were the main constituents.

Three young adults, all drivers involved in three separate motor vehicle accidents that occurred in Portage County, Ohio, during a three-week period, sustained blunt, nonpenetrating chest trauma that resulted in right atrial rupture and cardiac tamponade. On arrival in the emergency department, all were hypotensive and complained of chest pain; only one had jugular venous distension and upper body cyanosis. All had normal chest radiographs, and one had ECG ST elevation. Echocardiography showed a moderate-sized pericardial effusion and signs of cardiac tamponade in all three. Two of the three survived emergency thoracotomy and repair of the right atrial rupture. These cases demonstrate the importance of echocardiography in diagnosing cardiac tamponade as the classic signs are not always present.
