Fig. 2. Pancreas of guinea pig starved for 4S hours. Limitetl held ui the basal cytoplasm of 

 an acinar cell. A li[)id inclusion appears surroimiled h\ a complete mitochondrial ring. The 

 lipid mass is in ilirect contact with the mitochondrion o\'er its entire perimeter. At the periphery 

 of the mitochondrial ring the two mitochondrial membranes can be distinguisheil ; the inner 

 menihr.me (/ni) appears thicker and denser than the outer membrane (oni). R.uli.ilK' disposetl 

 cristae mitochondriales (short iinoifs) and intramitochondrial granules (long arroH's) can be 

 seen within the mitochondrial profile. Rough -surfaced elements of the endoplasmic reticulum 

 {rs) surround the lipid-mitochondrial complex. X 47>ooo.
