In vitro effects of delta 9-tetrahydrocannabinol (delta 9-THC), delta 8-tetrahydrocannabinol (delta 8-THC), cannabinol (CBN) and cannabidiol (CBD) have been studied on the uptake and release of 3H-labeled dopamine (DA) and norepinephrine (NE) in the synaptosomal preparation of rat brain corpus striatum and hypothalamus. The uptake of both DA and NE in these(More)
Single or repeated (for 15 consecutive days) oral administration of kalmegh leaf extract (500 mg/kg) or its bitter principle, andrographolide (5 mg/kg), to adult male albino rats (b.wt. 125-150 g) produced no significant change in NADPH induced hepatic microsomal lipid peroxidation. Carbontetrachloride (5 ml/kg) induced hepatic microsomal lipid peroxidation(More)
Administration of pentylenetetrazol (PTZ) (60 mg/kg, s.c.) to normal or carbaryl (200 mg/kg, p.o.) treated adult male albino rats produced characteristic changes in the steady-state levels of striatal dopamine (DA), noradrenaline (NA) and homovanillic acid (HVA) at different time intervals (0.5, 1.0 and 2.0 hr). The elevation of striatal NA level was found(More)
Exposure (2 h) of male albino rats to higher environmental temperature (HET, 40 degrees C) significantly increased the body temperature (BT). Administration of bicuculline (1 mg/kg, i.p.), physostigmine (0.2 mg/kg, i.p.), or their combination significantly raised the BT of normal rats (kept at 28 degrees C) or of HET-exposed rats. Atropine (5 mg/kg, i.p.)(More)
