Effects of para-chlorophenylalanine upon brain stimulated affective attack in the cat.

چکیده
Previous investigations of the effects of parachlorophenylalanine (PCPA) on affective attack have produced equivocal results. The present report examined the effects of PCPA upon attack elicited by electrical stimulation of the ventromedial hypothalamic nucleus in the cat. Using a within-animals design and postdrug testing clear potentiation of affective attack patterns was observed for a number of the components of attack behavior (approach, use of forepaws, and biting). The present results may point to possible serotonergic involvement in the inhibitory control of several aspects of affective attack.

Effect of p-CPA Pretreatment on EEG Power Spectra in Experimental Open Brain Injury in Rats
Continuous four hours EEG (electroencephalogram) recordings and its power spectrum analysis using fast fourier transform (FFT) in urethane anesthetized male Charles Foster rats were performed in two groups: open brain injury and p-CPA (para-Chlorophenylalanine) pretreated before brain injury, respectively, and compared with the EEG power spectrum of control rats. The EEG power spectrum analysis...

Brain serotonin content regulates the manifestation of tramadol-induced seizures in rats: disparity between tramadol-induced seizure and serotonin syndrome.
BACKGROUND Tramadol-induced seizures might be pathologically associated with serotonin syndrome. Here, the authors investigated the relationship between serotonin and the seizure-inducing potential of tramadol. METHODS Two groups of rats received pretreatment to modulate brain levels of serotonin and one group was treated as a sham control (n = 6 per group). Serotonin modulation groups receiv...
متن کاملSerotonin and the control of ventilation in awake rats.
In awake, unrestrained, intact rats, reserpine, para-chlorophenylalanine, 6-fluorotryptophan, and para-chloroamphetamine depleted whole brain serotonin and produced a substantial and sustained hyperventilation as evidenced by a 5--9 torr drop in PaCO2. Administration of 5-hydroxytryptophan to rats treated with para-chlorophenylalanine partially alleviated the hyperventilation. No change in vent...

Objective(s): In the present study, C57BL/6 female mice (n=56) were used to explore the neuroprotective effects of riboflavin in motor disability of experimental autoimmune encephalomyelitis (EAE) as a model of multiple sclerosis. Materials and Methods: The animals were assigned into 7 groups: sham-operated 1 (SO1), healthy mice receiving PBS (phosphate buffer saline); sham-operated 2 (SO2), h...
