[Sterol composition of sarcolemma in normal rabbits and in experimental muscular dystrophy]

In the rabbit sarcolemma both in norm and under experimental muscular dystrophy besides cholesterol there are found squalene and lanosterol - predecessors of its synthesis as well as a series of other sterols which are not yet identified. The cholesterol fraction of sarcolemma of the rabbits in norm and under muscular dystrophy contain so-called rapid sterols. Under experimental muscular dystrophy in the rabbit sarcolemma side by side with an increase in the content of cholesterol content the concentration of rapid sterols increases. It is also found that under mentioned pathology desmosterol arises in the rabbit sarcolemma.
