Presence of Widened and Multiple Intercalated Discs in the Hypertrophied Canine Heart

Presence of Widened and Multiple Intercalated Discs in the Hypertrophied Canine Heart

Fresh tissues were taken for light microscopy from the trabeculae carneae at the right ventricular base, apex, left ventricular base, and apex of four normal canine hearts and nine whose pulmonary artery had been banded for 7 to 48 weeks. After banding, the width of the intercalated disc at the righ...

Zusammenfassung:Fresh tissues were taken for light microscopy from the trabeculae carneae at the right ventricular base, apex, left ventricular base, and apex of four normal canine hearts and nine whose pulmonary artery had been banded for 7 to 48 weeks. After banding, the width of the intercalated disc at the right base, 1.34 ± 0.10 μ (mean ± SE), was greater than at the right apex, 1.02 ± 0.09 μ (P
