title: Microtubular formations inside GER of dog spinal ganglion neurons.
abstract: Partial spinal cord ischaemia was induced in dogs, ranging from 1 to 3 years of age, by ligature of the abdominal aorta just below the arteria coeliaca. The changes of the lumbal sensitive ganglia neurons were studied. In addition to the most often occurring changes, e.g., the vacuolization of the mitochondria, the disaggregation of ribosomes, the dilatation of the Golgi complex, the microtubular formations in the dilated cisterns of the endoplasmic reticulum were observed. Modified cisterns of the granulated endoplasmic reticulum (GER) occurred focally in relatively well preserved neurons. The individual microtubules measured about 24 nm in outer diameter, and their walls were formed by some subunits.
