Effects of Cytochrome c on Liver Functions of Old Rats

WE have shown^1,2 that cytochrome c, when orally administered, is absorbed intestinally. The effects of parenterally administered cytochrome c on the liver have been studied by Drabkin³ and Murano⁴. We have also studied the effects of orally administered cytochrome c on experimental liver injury⁵.     

Uptake and Metabolism of Sugars by Suspension Cultured Catharanthus roseus Cells

The uptake and metabolism of sugars by suspension-cultured Catharanthusroseus cells were investigated. Substantially all the sucrosein the culture medium was hydrolyzed to glucose and fructosebefore being taken up by the cells. The activity of invertasebound to cell walls, determined in situ, was high at the earlystage of culture. Glucose was more easily taken up by the cellsthan was fructose. Tracer experiments using [U-¹⁴C]glucose and[U-¹⁴C]fructose indicated that glucose is a better precursorfor respiration than fructose, while fructose is preferentiallyutilized for the synthesis of sucrose, especially in the earlyphase of cell growth. Possible metabolic routes of sugar insuspension-cultured Catharanthus roseus cells are discussedin the context of these results.
