We automated a kinetic procedure for determining amylase isoenzymes in serum and urine samples. We used 4-nitro-phenylmaltoheptaoside as substrate and a selective amylase inhibitor with the Abbott-VP bichromatic system. By use of the maximum differences between pancreatic (P) and salivary (S) amylase activities remaining after inhibition by the selective(More)
Using tympanometry we investigated potential changes in both middle ears developing during and after unilateral acute otitis media (AOM) in Japanese children. In 144 children with unilateral AOM, tympanometry was performed at presentation and was repeated at the 1st, 2nd, 3rd, and 4th weeks and then every 2 weeks up to 12 weeks after entry into the study.(More)
We investigated the correlation between body sway and head sway in 64 healthy subjects who stood on a force-measuring platform. Each subject wore a helmet attached to a cephalograph and was asked to stand as still as possible on a platform with his feet close together for 60 sec. Subjects were asked to do this three times with their eyes closed and three(More)
To clarify the relationship between vestibular and visual (optokinetic) stimuli in normal children, we investigated the vestibulo-ocular reflex (VOR) and visual VOR (VVOR). The subjects were 20 healthy children aged 3-6 years and 24 healthy adults aged 21-29 years. The VOR gains and phase were measured under two visual conditions: with eyes open in complete(More)
