Coincidentally, in the collection of damaged myocardial tissue, thrombosis was detected in the atrium. The incidence reached 75% in mice given 4 mg\/kg DX iv 10 times. They were white thrombi consisting of the fibrin, platelets, and neutrophils. Cardiac muscle damage was more prominent in the atria than in the ventricles. Light microscopically, vacuolization and degeneration of atrial myocytes and interstitial inflammatory cell infiltration were observed. Electron microscopy revealed dilatation of the sarcoplasmic reticulum and an increase in number of normal and\/or degenerate mitochondria. Inflammation extended from the cardiac muscle to the endocardium. The cause of atrial thrombosis in DX-treated mice is unknown but may relate to endocardial damage and changes of blood flow in the atrium secondary to cardiac muscle damage. DX-treated mice could serve as an experimental animal model for the evaluation of efficacy and toxicity of antithrombotic or antiplatelet drugs.<\/jats:p>","DOI":"10.1177\/019262339302100403","type":"journal-article","created":{"date-parts":[[2009,9,14]],"date-time":"2009-09-14T21:30:11Z","timestamp":1252963811000},"page":"362-368","source":"Crossref","is-referenced-by-count":24,"title":["The High Incidence of Atrial Thrombosis in Mice Given Doxorubicin"],"prefix":"10.1177","volume":"21","author":[{"given":"Shiro","family":"Fujihira","sequence":"first","affiliation":[{"name":"Department of Pathology, Toxicology Research Laboratories"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takao","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Product Development Laboratories, Fujisawa Pharmaceutical Co., Ltd., Kashima 2-1-6, Yodogawa-ku, Osaka 532, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahiro","family":"Matsumoto","sequence":"additional","affiliation":[{"name":"Department of Pathology, Toxicology Research Laboratories"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katsuhiko","family":"Yoshizawa","sequence":"additional","affiliation":[{"name":"Department of Pathology, Toxicology Research Laboratories"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuji","family":"Oishi","sequence":"additional","affiliation":[{"name":"Department of Pathology, Toxicology Research Laboratories"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshiyuki","family":"Fujii","sequence":"additional","affiliation":[{"name":"Department of Pathology, Toxicology Research Laboratories"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hideyo","family":"Noguchi","sequence":"additional","affiliation":[{"name":"Department of Pathology, Toxicology Research Laboratories"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Mori","sequence":"additional","affiliation":[{"name":"Department of Pathology, Osaka Medical College, Daigaku-machi 2\u20137, Takatsuki 569, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1993,6,1]]},"reference":[{"key":"atypb1","first-page":"1877","volume":"63","author":"Bertazzoli C","year":"1979","journal-title":"Cancer Treat.
