moreover , at the ultrastructural level , it was found that ( 1 ) the volume fraction of mitochondria in the cytoplasm decreases at doses of 12.5 and 50 mug/ml ( 2 ) the surface to volume ratio of the mitochondria is unchanged with any of the concentrations of lsd employed and ( 3 ) the surface density of the endoplasmic reticulum in the cytoplasm increases only with a dose of 2.5 mug/ml of lsd .
