Rat liver lysosomal and mitochondrial activities are modified by anabolic-androgenic steroids

Article Abstract:

Male rats were used in a study to determine the effects of anabolic-androgenic steroids on the liver. Hepatic functions and enzyme activities were analyzed. Damage to hepatocyte mitochondria and lysosomes were apparent. Correlations to human activity were hard to measure because most steroids used by humans are for short-term athletic activity that require power bursts rather than long-term endurance activity studied in rats. Also, it is not certain how the 8-week study should be correlated to the amount of time a human may use steroids.

Effects of anabolic-androgenic steroids on weight-lifters' myocardium: an ultrasonic videodensitometric study

Article Abstract:

Anabolic steroid use may alter the texture of the heart muscle of weight lifters. Using ultrasonic videodensitometry, researchers detected changes in the heart wall texture in ten weight lifters who used anabolic steroids. Particularly, the left ventricle was enlarged and an altered cycle variation index at various sites. No such physiological abnormalities were apparent in the hearts of ten weight lifters who never used steroids and a group of ten sedentary healthy adults.
