OBJECTIVE To study the prevalence of beryllium sensitization (BeS) and chronic beryllium disease (CBD) in a cohort of workers from a nuclear weapons research and development facility. METHODS We evaluated 50 workers with BeS with medical and occupational histories, physical examination, chest imaging with high-resolution computed tomography (N = 49), and(More)
the necessary operative procedures and by the physical confines of the chamber. The advantages realized by using the mem branous cheek pouch of the hamster as a site for transplantation are (a) the tumor grows freely without physical hindrance and in a normal physi ological environment; (b) the same tumor can be observed at successive stages (measured,(More)
tory effects of experimental hypercorticalism.3 The visual effects of ionizing radiation on the blood flow, small blood vessels, and endothelium of capillaries and venules in the hamster cheek pouch have been studied.4 As a basis for the correlation and interpretation of these observations with respect to changes in the usual hematologic values, we have(More)
The small venules of the hamster cheek pouch were rendered susceptible to hemorrhage by total body x-irradiation, cheek pouch x-irradiation and beta emanations from strontium-90 glass beads imbedded in the cheek pouch, as determined by negative pressure and moccasin venom tests. Petechiae were formed without vessel rupture and ceased without formation of(More)
• Experimental conditions have been described in which constriction of the small blood vessels in the cheek pouch of the golden hamster was found in association with increased serum potassium levels. The arterioles of adrenalectomized hamsters became progressively constricted, starting three to four days after operation until death. An increase in serum(More)
