Farkhakfar A, Hassanpour S, Zendehdel M. Resveratrol plays neuroprotective role on ketamine-induced schizophrenia-like behaviors and oxidative damage in mice. Neurosci Lett 2023; 813:137436. [PMID: 37586559 DOI: 10.1016/j.neulet.2023.137436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Revised: 08/01/2023] [Accepted: 08/10/2023] [Indexed: 08/18/2023]
Abstract
This study aimed to determine effects of the resveratrol on ketamine-induced schizophrenia-like behaviors and oxidative damage in mice. Twenty-four male mice were allocated into four experimental groups as control, ketamine (20 mg/kg), resveratrol (80 mg/kg) and co-administration of the ketamine (20 mg/kg) + resveratrol (80 mg/kg). Mice were received resveratrol for 30 days and ketamine was used for an animal model of schizophrenia and was injected from days 16 to 30 of the study. After the drug administration was finished, schizophrenia-like behaviors were evaluated using object recognition test, tail suspension test, forced swimming test and open field test and brain malondialdehyde, glutathione peroxidase, superoxide dismutase and catalase levels were determined. According to the results, ketamine treatment significantly decreased body weight and pretreatment with resveratrol elevated body weight compared to ketamine group (P < 0.05). Ketamine treatment significantly decreased number of the cross in open field test and pretreatment with resveratrol improved i (P < 0.05). Immobility time in tail suspension and forced swimming tests increased in mice treated with ketamine (P < 0.05). Pretreatment with resveratrol diminished immobility time compared to ketamine group (P < 0.05). Ketamine significantly decreased memory deficits while pretreatment with resveratrol significantly reduced the memory deficits induced by ketamine (P < 0.05). Brain MDA increased in both cortical and sub-cortical area in ketamine treated mice while pretreatment with resveratrol decreased ketamine-induced elevation in MDA (P < 0.05). Ketamine significantly decreased brain SOD, GPx and CAT levels while pretreatment with resveratrol improved SOD, GPx and CAT levels (P < 0.05). Findings suggested resveratrol has neuroprotective effects against ketamine-induced behavioral deficits and oxidative damages.

Abstract
The management of orofacial pain to alleviate the quality of life of affected patients is becoming increasingly challenging for scientific research and healthcare professionals. From this perspective, in addition to conventional therapies, new alternatives are being sought, increasingly looking at the use of both natural and synthetic products. Cannabis sativa L. represents an interesting source of bioactive compounds, including non-psychoactive cannabinoids, flavonoids, and terpenes, many of which are effective in improving pain intensity. Here, we aim to analyze the possible mechanisms of action of the bioactive natural and synthetic hemp-derived compounds responsible for the modulatory effects on pain-related pathways. The ability of these compounds to act on multiple mechanisms through a synergistic effect, reducing both the release of inflammatory mediators and regulating the response of the endocannabinoid system, makes them interesting agents for alternative formulations to be used in orofacial pain.

Yamaguchi M, Kinouchi R, Morizumi S, Shimazu Y, Takeda M. Local administration of genistein as a local anesthetic agent inhibits the trigeminal nociceptive neuronal activity in rats. Brain Res Bull 2021; 172:120-128. [PMID: 33895269 DOI: 10.1016/j.brainresbull.2021.04.015] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Revised: 04/13/2021] [Accepted: 04/19/2021] [Indexed: 10/21/2022]
Abstract
A modulatory role has been reported for the isoflavone, genistein, on voltage-gated Na+ channels in the trigeminal ganglion in vitro. However, the acute effects of genistein in vivo, particularly on nociceptive transmission in the trigeminal system, remain to be determined. The aim of the present study was to examine whether acute local genistein administration to rats attenuates the excitability of wide-dynamic range (WDR) spinal trigeminal nucleus caudalis (SpVc) neurons in response to nociceptive and non-nociceptive mechanical stimulation in vivo. Extracellular single unit recordings were made from SpVc WDR neurons in response to orofacial non-noxious and noxious mechanical stimulation of pentobarbital-anesthetized rats. The effects of local administration of genistein, lidocaine, and lidocaine with genistein to the receptive field on the discharge frequency of SpVc neurons were evaluated. The mean firing frequency of SpVc WDR neurons in response to both non-noxious and noxious mechanical stimuli was significantly and dose-dependently (0.1-10 mM) inhibited by genistein, and maximum inhibition of the discharge frequency of both non-noxious and noxious mechanical stimuli was seen within 10 min. The inhibitory effect of genistein lasted for 20 min and was reversible. No significant difference was seen between the relative magnitude of inhibition by genistein on the SpVc WDR neuronal discharge frequency for noxious and non-noxious stimulation. The mean magnitude of inhibition by genistein (10 mM) on SpVc neuronal discharge frequency was almost equal to that of the local anesthetic, 1 % lidocaine (37 mM). Local injection of half-dose of lidocaine replaced the half-dose of genistein. These results suggest that local injection of genistein into the peripheral receptive field suppresses the excitability of SpVc neurons, possibly via inhibition of voltage-gated Na+ channels in the nociceptive nerve terminals of trigeminal ganglion. Therefore, administration of genistein as a local anesthetic may provide relief from trigeminal nociceptive pain without side effects, thus contributing to the area of complementary and alternative medicines.
