Changes in Catecholamines and Acetylcholinesterase Levels of Crebellum, Mid-brain and Brain Cortex in Chromium Treated Rats
The short and long term effects of chromium toxicity on brain catecholamines and acetylcholinesterase levels were investigated. Rats were injected daily with varying amounts of chromium. The short term (2 h) administration of chromium (8 mmol/kg) reduced catecholamines level of cerebellum, mid-brain and brain-cortex by 22.8, 19.4 and 21.2% respectively. Acetylcholinesterase activity was also re...

متن کاملA mid-brain syndrome following head injury.
HAMORRHAGIC lesions of the brain stem are not infrequently found in fatal cases of accidental head injury. Duret (1878, 1919) emphasized their importance, and showed that they are easily produced in experimental animals. Bemer (1930) and Courville (1945) also considered them to be an important cause of death, and it is clear that only a very few patients who recover from a head injury are found...
متن کاملA Split (mid)brain for Dopamine
mitter that has a role in movement and many aspects of cognition. Lammel et al. have now characterized two types of neurons in the mesocorticolimbic dopamine system that are not only anatomically segregated, with non-overlapping axonal target regions, but that also have distinct molecular and functional properties. This structured diversity of the dopamine midbrain system might contribute to th...
