“Alkaline phosphatase activity was increased by fluoride combined with 10−9M cortisol and decreased by fluoride combined with 10−8M cortisol compared to the activities obtained with fluoride alone.”
“Ca2+-ATPase activity tended to be increased by combinations of fluoride and cortisol , but significantly so only at 10−5M fluoride in combinations with 10−8 and 10−9M cortisol.”
“ Fluoride (10−6M) combined with cortisol (10−9M) produced a peak of Na+,K+-ATPase activity.”
“HCO3−-ATPase activity was increased by fluoride combined with 10−8M cortisol and decreased by fluoride combined with 10−9M cortisol compared to the activities obtained with fluoride alone.”
“The decrease in Ca2+,Mg2+-ATPase activity caused by fluoride alone was prevented by 10−9 and enhanced by 10−8M cortisol , although all treatments produced the same activity at 10−5M fluoride.”
