## Abstract The effects of Tl^+^ ions on isolated rat liver mitochondria were studied in the presence of nonactin, a cyclic ionophore. Nonenergized rat liver mitochondria were increasingly swollen at an elevated concentration of Tl^+^ in the 160 mOsm medium containing 0β150 mM sucrose and 0β75 mM T

We studied action of inorganic phosphate (P i ) on toxic effects of Tl + in isolated rat liver mitochondria. This is a convenient model to study the toxicity of heavy metals. P i markedly retarded contraction of energized mitochondria swollen in the TlNO 3 medium and even stronger stimulated swellin
## Abstract Because of the frequent reports of hepatic toxicity associated with longβterm administration of methotrexate, a rat model was developed utilizing daily methotrexate administration. This model revealed an incidence of fatty metamorphosis of over 80 percent, atrophy and necrosis of 30 per
Edam type cheese was exposed to sunlight at ambienl temperature and to fluorescent light at 5 "C. The loss of vitamin B, (riboflavin) and vitamin A was monitored in both the surface and inner layers of the cheese and the results compared with control samples kept in the dark. The loss of riboflavin
