چکیده مقاله:

In the present study, the effects of caerulein and CCK receptor antagonist< on tolerance to the anti-pentylenetetrazol activity of diazepam has been studied. Different doses of diazepam (20, 30, 35, 40 and 50 mg/kg) were administered intraperitoneally for a period of 6 days in order to induce tolerance to diazepam. 48 h after the last dose of diazepam, a test dose of diazepam was tested for antipentylenetetrazol activity. When animals were treated with caerulein or the CCK receptor antagonists MK -329 and L-365,260, only L-365,260 reversed the tolerance to diazepam. It may be concluded that CCK-B receptor mechanisms may interact with tolerance induced by diazepam.

EFFECTS OF CCK RECEPTOR AGONISTS AND ANTAGONISTS ON MORPHINE-INDUCED ANTINOCICEPTION IN MICE

In the present study the effects of both CCK receptor agonists and antagonists on antinociception induced by morphine in the tail-flick test have been evaluated. M orphine induced dose-dependent antinociception in mice. The response of morphine was potentiated by sulfated cholecystokinin-8 (CCK-8S) but not by unsulfated cholecystokinin-8 (CCK-8U). The CCK receptor antagonists MK-329 and L-...

The effect of intracerebroventricular administration of CCK receptor agonist and antagonist in nerve-Iigated mice

In the present study the effect of intracerebroventricular (ICV) injection of cerulein, an agonist of CCK receptor and proglumide, a receptor antagonist for hyperalgesia induced by sciatic nerve ligation were investigated in mice. Subcutaneous administration of morphine caused anti-nociception in both intact and nerve-ligated mice. However, the response to opioids was lower in ligated mice as c...

The effect of CCK receptor agonists and antagonists in sciatic nerve-ligated mice

The effects of caerulin, a CCK receptor agonist, and proglumide, a receptor antagonist, on hyperalgesia induced by sciatic nerve ligation, was studied in mice. Tolerance to the morphine response was obtained 3,7, 14,21 and 28 days after unilateral sciatic nerve ligation. Maximum hyperalgesia was found 14 days after nerve ligation. Caerulin increased morphine antinociception in nerve-ligated ani...

Comparison of Different 2D and 3D-QSAR Methods on Activity Prediction of Histamine H3 Receptor Antagonists

     Histamine H3 receptor subtype has been the target of several recent drug development programs. Quantitative structure-activity relationship (QSAR) methods are used to predict the pharmaceutically relevant properties of drug candidates whenever it is applicable. The aim of this study was to compare the predictive powers of three different QSAR techniques, namely, multiple linear regression ...
