en Immunology Immunology Original Research: Basic Science in Medicine Original Research: Basic Science in Medicine Neutrophil mobility in 60 patients with vitamin D-deficient rickets is studied, and the patients are followed after therapy by 600,000 units vitamin D. 28 of 60 patients (46%), had low chemotaxis for neutrophils before vitamin D injection (migration), and 36 of 60 (60%) had low random mobility. The results showed a significant improvement after vitamin D therapy furthermore, the level of calcium and phosphorus reached normal levels after treatment of the patients as well. We have previously studied neutrophil mobility in 10 patients with rickets2 This report serves to complement our previous preliminary report. 169 173 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-298-786&slc_lang=en&sid=1 A FARHOUDI 20031947532846006561 20031947532846006561 Yes From the Immunology and Allergy Dept., Children s Medical Center, Tehran University of Medical Sciences, Tehran, Islamic Republic of Iran.
