T1 |
0-87 |
Sentence |
denotes |
Antipsychotic-like profile of thioperamide, a selective H3-receptor antagonist in mice. |
T2 |
88-209 |
Sentence |
denotes |
Experimental and clinical evidence points to a role of central histaminergic system in the pathogenesis of schizophrenia. |
T3 |
210-421 |
Sentence |
denotes |
The present study was designed to study the effect of histamine H(3)-receptor ligands on neuroleptic-induced catalepsy, apomorphine-induced climbing behavior and amphetamine-induced locomotor activities in mice. |
T4 |
422-744 |
Sentence |
denotes |
Catalepsy was induced by haloperidol (2 mg/kg p.o.), while apomorphine (1.5 mg/kg s.c.) and amphetamine (2 mg/kg s.c.) were used for studying climbing behavior and locomotor activities, respectively. (R)-alpha-methylhistamine (RAMH) (5 microg i.c.v.) and thioperamide (THP) (15 mg/kg i.p.), per se did not cause catalepsy. |
T5 |
745-894 |
Sentence |
denotes |
Administration of THP (3.75, 7.5 and 15 mg/kg i.p.) 1 h prior to haloperidol resulted in a dose-dependent increase in the catalepsy times (P < 0.05). |
T6 |
895-988 |
Sentence |
denotes |
However, pretreatment with RAMH significantly reversed such an effect of THP (15 mg/kg i.p.). |
T7 |
989-1150 |
Sentence |
denotes |
RAMH per se showed significant reduction in locomotor time, distance traveled and average speed but THP (15 mg/kg i.p.) per se had no effect on these parameters. |
T8 |
1151-1290 |
Sentence |
denotes |
On amphetamine-induced hyperactivity, THP (3.75 and 7.5 mg/kg i.p.) reduced locomotor time, distance traveled and average speed (P < 0.05). |
T9 |
1291-1394 |
Sentence |
denotes |
Pretreatment with RAMH (5 microg i.c.v.) could partially reverse such effects of THP (3.75 mg/kg i.p.). |
T10 |
1395-1476 |
Sentence |
denotes |
Climbing behavior induced by apomorphine was reduced in animals treated with THP. |
T11 |
1477-1535 |
Sentence |
denotes |
Such an effect was, however, reversed in presence of RAMH. |
T12 |
1536-1720 |
Sentence |
denotes |
THP exhibited an antipsychotic-like profile by potentiating haloperidol-induced catalepsy, reducing amphetamine-induced hyperactivity and reducing apomorphine-induced climbing in mice. |
T13 |
1721-1818 |
Sentence |
denotes |
Such effects of THP were reversed by RAMH indicating the involvement of histamine H(3)-receptors. |
T14 |
1819-1929 |
Sentence |
denotes |
Findings suggest a potential for H(3)-receptor antagonists in improving the refractory cases of schizophrenia. |
