Abstract:
To evaluate the release and possible role of N-terminal end of atrial natriuretic factor (ANF) prohormone (proANF-1-30) and C-terminal end of ANF prohormone (aANP-1-28) in patients with soft tissue and bone injuries, 20 patients with soft tissue injuries, 18 bone-fractured patients, and 21 healthy controls were examined. Samples were collected from patients within 24 h after injury. Plasma level of proANF-1-30 and aANP-1-28 were higher in orthopedic patients than the soft tissue injury patients compared to controls (P < 0.005, P<0.05, respectively). proANF-1-30 was over 15-fold greater than aANP-1-28 in the healthy control samples. These data hypothesized that the concentration of proANF-1-30 may be related to tissue damages in man.
