The clinical implications of a wider distribution of salivary type (S-type) isoamylase activity, as compared with that of pancreatic type (P-type) isoamylase activity in the serum of young female adults of 18-23 years old was studied. A high correlation existed between the S-type isoamylase levels in the initial determination and those in the second determination one year after on the same subjects, indicating that the wider distribution of S-type isoamylase level reflects an individual variation. The serum level of S-type isoamylase was highly correlated with the S-type isoamylase activity in saliva. Among the additional factors studied, a weak positive correlation was present between energy intake and the total and S-type isoamylase activities in serum. However, there was no negative correlation between the S-type isoamylase level and body mass index (BMI), which was reported for young male adults.
