in the patients with rheumatoid arthritis there was a statistically significant correlation between the serum histidine concentration and the following : westergren sedimentation rate ( r=-0.33 , p smaller than 10- minus 9 ) , grip strength ( r=0.26 , p smaller than 10- minus 9 ) , hematocrit ( r=0.23 , p smaller than 10- minus 9 ) , duration of morning stiffness ( r=-0.14 , p=10- minus 5 ) , walking time ( r=-0.13 , p=10- minus 4 ) , latex titer of rheumatoid factor ( r=-0.11 , p=0.001 ) , and the duration of arthritis ( r=-0.06 , p=0.05 ) .
