Ultrastructural features of ethanol-induced cardiomyopathy in turkey poults. 1985

C M Czarnecki, and S W Schaffer, and O A Evanson

Alcoholic cardiomyopathy, characterized by cardiac hypertrophy, was induced in young turkey poults with 5% ethanol. Ultrastructural features included accumulation of glycogen, swollen mitochondria, myofibrillar lysis, increased number of lysosomes, dilated sarcoplasmic reticulum and dense myofibers. Similarity of these alterations to those described in human alcoholic cardiomyopathy confirms the usefulness of the turkey poult as an animal model for this disease syndrome.

UI	MeSH Term	Description	Entries
D008247	Lysosomes	A class of morphologically heterogeneous cytoplasmic particles in animal and plant tissues characterized by their content of hydrolytic enzymes and the structure-linked latency of these enzymes. The intracellular functions of lysosomes depend on their lytic potential. The single unit membrane of the lysosome acts as a barrier between the enzymes enclosed in the lysosome and the external substrate. The activity of the enzymes contained in lysosomes is limited or nil unless the vesicle in which they are enclosed is ruptured or undergoes MEMBRANE FUSION.

D009206	Myocardium	The muscle tissue of the HEART. It is composed of striated, involuntary muscle cells (MYOCYTES, CARDIAC) connected to form the contractile pump to generate blood flow.

D002310	Cardiomyopathy, Alcoholic	Disease of CARDIAC MUSCLE resulting from chronic excessive alcohol consumption. Myocardial damage can be caused by: (1) a toxic effect of alcohol; (2) malnutrition in alcoholics such as THIAMINE DEFICIENCY; or (3) toxic effect of additives in alcoholic beverages such as COBALT. This disease is usually manifested by DYSPNEA and palpitations with CARDIOMEGALY and congestive heart failure (HEART FAILURE).	Alcoholic Cardiomyopathy

D006003	Glycogen
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
