Measurement of [Ca²⁺]_i in neonatal rat cardiomyocytes.

<p>Fluorescent intensity in [Ca2+]i was recorded by laser scanning confocal microscope in different treatment. (A) Representative images of cardiomyocytes. (B and C) Bar graph of fluorescent intensity. All data were expressed as mean±SEM (<i>n</i> = 6). *<i>P</i><0.05 compared with control group; @<i>P</i><0.05 compared with model group; #<i>P</i><0.05 compared with model+GdCl3 group; &<i>P</i><0.05 compared with control group. Groups in B were control, model, model+GdCl3, model+NPS-2390+GdCl3, model+NPS-2390, and control+GdCl3. Groups in C were control, model, model+GdCl3, siRNA+model+GdCl3, nRNA+model, and siRNA+model. Glucose: 25.5 mM; GdCl3: 300 µM; NPS-2390: 10 µM.
