Two peptides that crossreact with an antiserum raised against Phe-Met-Arg-Phe-NH2 were purified from bovine brain extract. Their structures were determined to be Ala-Gly-Glu-Gly-Leu-Ser-Ser-Pro-Phe-Trp-Ser-Leu-Ala-Ala-Pro-Gln-Arg-Phe- NH2 and Phe-Leu-Phe-Gln-Pro-Gln-Arg-Phe-NH2. The sequences were determined by gas-phase sequencing, except for the COOH-terminal phenylalaninamides. These were as...

OBJECTIVE We compared the effects of 2 sedative drugs, dexmedetomidine and midazolam, on motor performance and analgesic efficacy in a rat model. MATERIALS AND METHODS Rats were randomly divided into the following 4 groups on the basis of the treatment received. The first group received 83 µg/kg/min midazolam; the second, 1 µg/kg/min dexmedetomidine; the third, 83 µg/kg/min morphine; and the ...

The present study aimed to investigate the anti-inflammatory and anti-nociceptive potential of a hydroethanolic extract of Tamarindus indica L. leaves (HTI) along with its possible mode of action. The anti-inflammatory activity of HTI was estimated by carrageenan-induced hind paw oedema in male Wistar albino rats. Furthermore, HTI was assessed to determine its effects on membrane stabilization....

Momordica Charantia (MC) is one of the most famous traditional plant worldwide, used for the treatment of diabetes and its complications. In the present study possible protective effect of MC in Streptozotocin (STZ) induced diabetic neuropathy in mice was evaluated. STZ induced diabetic mice were orally administered MC at various doses (200 800 mg/kg) for six weeks. Diabetes induced neuropathic...

OBJECTIVES To study the balance between the pro-oxidative and antioxidative defence system after repeated painful stimulation in rats and the efficacy of the administration of different antioxidants (vitamins C, E, A, and selenium), analgesics (acetylsalicylic acid, morphine), and their combinations. METHODS Mechanical clamping of both hind limbs was applied for 10 min for 5 consecutive days ...

The brain stem reticular formation plays an important role in determining consciousness and arousal. Modulation of cholinergic neurotransmission in this region alters the sleep-wake cycle. In the present study, we examined the effect of the direct application of cholinergic agents into the pontine reticular nucleus on anesthetic requirements and recovery and antinociception in rats. Sprague-Daw...

objective: it has been shown that silybum marianum or its extracts have hepatoprotective, antioxidant, anticancer, anti-inflammatory and anti-diabetic effects. nitric oxide (no) plays an important role in neurotransmission, neuroprotection, neurotoxicity and pathological pain, as a neurotransmitter or neuromodulator in the central nervous system. therefore, this experiment was performed in orde...

Zingiber officinale Roscoe, commonly known as ginger, is a traditional herb used to treat various disorders. In this study, we evaluated potential pharmacological effects of ethanolic extracts of Z. Officinale with respect to central nervous system (CNS) activity in mice. Role of ethanolic extract of ginger on CNS activity in mice was studied using models of elevated plus maze test, barbiturate...

Role of ethanolic extract of P. granatum seeds on central nervous system (CNS) in animal models of elevated plus maze test, barbiturate-induced sleeping time, tail suspension test, hot-plate and tail-flick test was studied. P. granatum (PG) extract was administered to young and aged mice at single doses of 100, 250 and 500 mg/kg, perorally while diazepam (1 mg/kg), morphine (5 mg/kg) and imipra...
