title: [Effects of prolonged fasting and vagotomy on the ultrastructure of contractile myocardium in pigeons].
abstract: Ultrastructural changes in pigeon heart following long fasting and vagotomy are reported. In the fasting pigeons several fat droplets surrounding the adjacent nearest mitochondria represent the most important finding. Conversely, in the fasting and vagotomized pigeons the mean finding is a large decrease of fat droplets. Ultrastructural findings appear related with biochemical changes by different experimental conditions.
