Ultrastructure and biochemical studies of rat CNS and viscera after subcutaneous injection of chlorphentermine.
|
| Abstract |
Ultrastructural and biochemical studies were carried out on three groups of experimental models which were induced by a single subcutaneous daily dose of 10 to 40 mg./kg. body weight of chlorphentermine hydrochloride. The first group consisted of 20 young adult rats which were sacrificed at intervals of from one to four weeks. The liver and lungs showed concentrically arranged memberanous bodies in the hepatocytes and alveolar cells during the first week after the first injection, while the CNS and pancreas showed no ultrastructural alterations. During the fourth week, the pancreas displayed abnormal cytoplasmic inclusion bodies in the A and B cells of the islets of Langerhans as well as in the exocrine portion. The brain showed various neuronal alterations at four weeks which consisted of irregular dense bodies to well-developed membranous structures which were similar to those of Tay-Sachs disease. Biochemically, thin layer chromatograms showed that the major ganglioside fraction in the brain at four weeks had an RF value similar to that of GM1-ganglioside. In an analysis of the total N-acetyl neuraminic acid the brains in the experimental group contained 90.9% GM1-gandlioside as compared with 44% in the controls. The total and fractions of phospholipids in the brains and livers of the experimental animals were within normal limits.
