Activities of choline acetyltransferase (ChAT) were microassayed in individual cell bodies of motor neurons, isolated from freeze-dried sections after autopsy of lumbar spinal cords from four patients with sporadic amyotrophic lateral sclerosis (ALS) and four control patients with nonneurological diseases. Numerous large neurons were found in the anterior(More)
Phosphoinositide turnover stimulated by 5-hydroxytryptamine (5-HT) receptors in the intact rat brain was studied using an in vivo method. Phosphoinositides in the rat brain were prelabeled with [3H]inositol injected into the lateral cerebral ventricles. The rats were killed by microwave irradiation after 48 h and the contents in the frontal cortex of(More)
Acyl-CoA thioesterases (Acots) are enzymes that catalyze the hydrolysis of fatty acyl-CoAs to free fatty acids and coenzyme A, and have the potential to regulate the intracellular levels of these molecules. In this study, we show that a cytosolic isoform, Acot1, is expressed and distributed in immature adipocytes located in the perivascular region of the(More)

An enzymatic assay for choline acetyltransferase was developed by measuring acetyl-coenzyme A (acetyl-CoA) formed from CoASH and acetylcholine (ACh). This method is extremely sensitive and may be applied to the analysis of microgram to nanogram crude samples. The method is, however, not useful when choline acetyltransferase is present in very low(More)
Stereotaxic microinjection of veratrine (50 micrograms in 1 microliter of saline) into the preoptic anterior hypothalamus of rats which were intraperitoneally pretreated with haloperidol (1 mg/kg), significantly elevated body temperature (1.4 degrees C above normal body temperature) and produced abnormal behaviors. This microinjection also facilitated(More)
