The atrial myocardium of buffalo was composed of syncytially arranged myocardial cells which were branched and anastomosed freely. The atrial myocardial cells were thinner and less regular than the ventricular ones. These cells showed very strong reactions for proteins, Ca salts and DNA in their nuclei; strong reaction for PAS[periodic acid Schiff]-positive substances and glycogen; moderate reactions for protein-bound NH2, fatty acids, phospholipids, tyrosine, bound lipids and fats; and negative reactions for acid and sulfated mucopolysaccharides, ferric and ferrous salts. The reaction for alkaline phosphatase was strong.
