We aimed to investigate the angiotensin-converting enzyme (ACE) gene polymorphism, ACE activity and their associations with diabetic complications in Turkish patients with type 2 diabetes mellitus. A total of 143 patients and 133 controls were screened for ACE gene I/D polymorphism by using polymerase chain reaction. Serum ACE activities were determined(More)
The aim of this study is to detect the incidence of the angiotensin-converting enzyme (ACE) gene polymorphism in Turkish asthmatic patients and to examine whether there is an association between the disease and ACE gene polymorphism. In our study, the genomic DNA of 100 asthmatic patients and 88 healthy subjects was analyzed Genomic DNA was isolated from(More)
