Altogether 140 random-bred dogs of both sexes, aged 2 to 4 (body mass 14.5 +/- 0.1 kg) were examined. Age-related changes of heart mass entropy, resulting from disorder in the correlation of cardiac parts during aging, progress with age. During inhalation of acute, subacute and chronic effective amounts of nitrates of polymeric 239Pu and monomeric 241Am aerosol particles, measured in micron, dog heart mass entropy increases as compared to the age control, and during inhalation of transuranic radionuclides at small amounts, causing the animals' life prolongation, heart mass entropy decreases.
总共检查了140只2至4岁（体重14.5±0.1千克）的随机繁殖的雌雄犬。心脏质量熵的年龄相关变化是由于衰老过程中心脏各部分相关性紊乱所致，且随年龄增长而进展。在吸入以微米为单位测量的聚合态239Pu和单体态241Am气溶胶颗粒的急性、亚急性和慢性有效剂量硝酸盐期间，与年龄对照组相比，犬的心脏质量熵增加；而在吸入少量超铀放射性核素导致动物寿命延长期间，心脏质量熵降低。
