Abstract

Objective: There are evidences that proadrenomedullin N-terminal 20 peptide (PAMP) and calcitonin may be involved in cardiovascular function. Therefore, we studied effects of rat PAMP and human PAMP as well as rat calcitonin and salmon calcitonin on coronary perfusion pressure, heart rate and contractile force.Methods: Isolated rat hearts were perfused under constant flow condition and rat PAMP (1.10 and 100 nM), human PAMP (1,10 and 100 nM), rat calcitonin (10.100 and 1000 nM) or salmon calcitonin (10.100 and 1000 nM) were infused to the hearts. Coronary perfusion pressure, heart rate, left ventricular developed pressure and +dP/dtmax were measured. Statistical analysis was performed using repeated measures ANOVA and Bonferroni posthoc tests.Results: Rat PAMP (1.10 and 100 nM) did not alter perfusion pressure. However, it increased heart rate from 257.83 ± 23.89 to 282±24.98 beats/min (p

Özet

Amaç: Proadrenomedullin N-terminal 20 Peptit’in (PAMP) ve kalsitoninin kardiyovasküler fonksiyonda işe karışabileceği hakkında kanıtlar vardır. Bu nedenle sıçan PAMP’ın, insan PAMP’ın, sıçan kalsitonin’in ve somon kalsitonin’in koroner perfüzyon basıncına, dakikada kalp atım sayısına ve kasılma kuvvetine etkilerini araştırdık. Yöntemler: İzole sıçan kalpleri sabit akım durumunda perfüze edildi ve sıçan PAMP (1.10 ve 100 nM), insan PAMP (1.10 ve 100 nM), sıçan kalsitonin (10.100 ve 1000 nM) veya somon kalsitonin (10.100 ve 1000 nM) kalplere verildi. Koroner perfüzyon basıncı, dakikada kalp atım sayısı, sol ventrikülün geliştirdiği basınç ve +dP/dtmax ölçüldü. İstatistiksel analiz tekrarlanan ölçümler için ANOVA ve Bonferroni testleri kullanılarak yapıldı. Bulgular: Sıçan PAMP (1.10 ve 100 nM) perfüzyon basıncını değiştirmedi. Fakat dakikada kalp atım sayısını 1.10 ve 100 nM dozlarında sırası ile 257.83±23.89’dan 282.00±24.98 atım/dakika’ya (p
