Effects of dietary selenium ad vitamin E on he gray-tailed vole

Creator:: Pond, Finn Richard
Abstract:: The gray-tailed vole (Microtus canicaudus) demonstrated a requirement for selenium and vitamin E. Animals deficient in both nutrients suffered from liver necrosis and an unthrifty condition characterized by inappetence, profuse diarrhea, and swollen eyes. Vitamin E appeared less effective than selenium as a prophylaxis against this syndrome. Total body weights,...

Ionizing radiation and its chemical effects : a historical study of chemical dosimetry (1902-1962)

Creator:: Chorzempa, Mary André, Sister
Abstract:: Chemical dosimetry developed in response to needs created by developments in the field of high-energy radiation. Shortly after the discovery of X-rays in 1895 and of radioactivity in 1896, the deleterious effects of ionizing radiation were recognized. To guard against the injurious effects of radiation in medical application, dose-measuring methods...
