The effects of thyroidectomy, estradiol treatment, and thyroxine treatment on plasma and liver protein concentrations in the water snake, Natrix fasciata fasciata (Linnaeus, 1766), were investigated. There was a significant lowering of liver protein concentrations following thyroidectomy. This deficit could be replaced with thyroxine alone, but could not be replaced by treatment of thyroidectomized snakes with estradiol alone or with a combination of estradiol and thyroxine.
The plasma resolved into nine plasma proteins when electrophoresed in polyacrylamide gels. Although thyroidectomized snakes treated with estradiol only or a combination of estradiol and thyroxine showed enhancement in two protein fractions, the significance can not be drawn due to lack of zero time data.
