The tissues examined were cerebrum, spinal cord, dorsal root ganglia and retina. Chloroquine was given in the diet in doses of 2.0\u20103.5 g\/kg food. The intoxication of the pigs was started at the age of 100\u2013240 days and continued for 177\u2010219 days. The control pigs received the same diet without chloroquine. The ganglioside concentration was increased in all the tissues examined. Dorsal root ganglia and retina were the tissues affected most and showed a twofold increase. This corresponded to the light and electron microscopically demonstrated extensive storage process in the perikarya of dorsal root ganglion cells and inner ganglion cells of the retina. Under light microscopy the storage material was granular, intensely PAS\u2010positive and dissolved by paraffin embedding. The electron microscopical equivalent consisted of conglomerates of membranous lysosomal residual bodies. In cerebrum the ganglioside concentration was increased by 12%. Storage in the brain varied widely between different systems and types of cells. The allocortex was much more affected than the isocortex. Certain inhibitory ganglion cell types, such as the basket cells, exhibited the most massive storage of all. The spinal medulla was morphologically less involved but showed approximately the same ganglioside increase, though not statistically significant. With the exception of cerebrum the increase in the tissues examined involved all the individual gangliosides, most severely ganglioside GM2 and three fucogangliosides. In cerebrum only the ganglioside GM2 was increased more than the other gangliosides. Chloroquine intoxication did not affect the concentration of phospholipids or cholesterol in the cerebrum, spinal cord or dorsal root ganglia, but in retina the acidic phospholipids were significantly increased.<\/jats:p>","DOI":"10.1111\/j.1471-4159.1981.tb04477.x","type":"journal-article","created":{"date-parts":[[2006,10,5]],"date-time":"2006-10-05T11:37:42Z","timestamp":1160048262000},"page":"897-908","source":"Crossref","is-referenced-by-count":32,"title":["Chloroquine Intoxication Induces Ganglioside Storage in Nervous Tissue: A Chemical and Histopathological Study of Brain, Spinal Cord, Dorsal Root Ganglia, and Retina in the Miniature Pig"],"prefix":"10.1111","volume":"37","author":[{"given":"Georg W.","family":"Klinghardt","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pam","family":"Fredman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lars","family":"Svennerholm","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,10,5]]},"reference":[{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0009-8981(58)90025-1"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0006-2952(74)90174-9"},{"key":"e_1_2_2_4_1","unstructured":"FredmanP.(1979)Structure and function of gangliosides.Thesis University of Gothenburg."},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/0014-5793(80)80028-7"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/0005-2760(80)90052-1"},{"key":"e_1_2_2_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1432-1033.1981.tb05372.x"},{"key":"e_1_2_2_8_1","doi-asserted-by":"crossref","first-page":"7854","DOI":"10.1016\/S0021-9258(19)40894-6","article-title":"Inhibition of proteolytic degradation of low density lipoprotein in human fibroblasts by chloroquine, concanavalin A and Triton WR 1339","volume":"250","author":"Goldstein J.
