CRP and asthma: Therefore, in the present study, we considered it a prerequisite to investigate the relationship between job strain and CRP in order to clarify that between job strain and arginase I. However, in this study, job strain was inversely associated with arginase I. Social support was positively associated with arginase I. Previously, we showed a high serum level of arginase I in asthma and the correlation of arginase I with hs-CRP [30], as well as the association of arginase I with oxidative stress [17, 18].
