Stimulating effect of angiotensin II on the spontaneous release of newly synthetized [3H]dopamine in rat striatal slices. | Angiotensin II (A II) (10(-6) M, 10(-5) M, 5 . 10(-5) M) stimulated the spontaneous release of [3H]dopamine (DA) continuously synthetized from [3H]tyrosine in striatal slices of the rat. The A II-evoked release of [3H]-DA was prevented when slices were superfused with a calcium-free medium containing EGTA 5 . 10(-4) M.... | 530,525 | [

Tremor: role of striatal cholinergic neurons and the effect of intrastriatal kainic acid. | Rats injected intrastriatally with kainic acid (KA) showed increased tremor responses to arecoline and tremorine, but not to harmaline. Since KA significantly reduced both pre- and postsynaptic measurements of cholinergic function in the striatum, the results indicate that integrity of the striatal cholinergic system i... | 530,529 | [

It can be demonstrated morphologically that changes--particularly qualitative changes--in collagen are accompanied by a more or less severe los... | 530,892 | [
