Betaine alleviates right ventricular failure via regulation of Rho A/ROCK signaling pathway in rats with pulmonary arterial hypertension.

Pulmonary vascular remodeling was shown to lead to pulmonary arterial hypertension (PAH), further trigger excessive apoptosis of cardiomyocytes, and ultimately cause right ventricular failure (RVF), which involves the activation of Rho A/ROCK signaling pathway. Betaine has been found efficacious for attenuating PAH through its anti-inflammatory effects in our previous research while its effects on RVF due to PAH remains inconclusive. Thus, we attempted to elucidate the protective effects of betaine on PAH, RVF due to PAH as well as the potential mechanisms.

Neuroprotective effect of liquiritin against neuropathic pain induced by chronic constriction injury of the sciatic nerve in mice.

Managing of neuropathic pain remains clinically challenging because the existing pharmacotherapies are either ineffective or non-specific. Therefore, developing novel alternatives is essential for better treatment. Liquiritin is an active component extracted from Glycyrrhizae radix and has potential neuroprotective action.

Anticonvulsant Effect of Swertiamarin Against Pilocarpine-Induced Seizures in Adult Male Mice.

Epilepsy is one of the common and major neurological disorders, approximately a third of the individuals with epilepsy suffer from seizures and not able to successfully respond to available medications. Current study was designed to investigate whether Swertiamarin (Swe) had anticonvulsant activity in the pilocarpine (PILO)-treated mice. Thirty minutes prior to the PILO (280 mg/kg) injection, the mice were administrated with Swe (50, 150, and 450 mg/kg) and valproate sodium (VPA, 200 mg/kg) once.

Neuroprotective Effects of Lycium barbarum Polysaccharide on Focal Cerebral Ischemic Injury in Mice.

Increasing evidence demonstrates inflammation contributes to neuronal death following cerebral ischemia. Lycium barbarum polysaccharide (LBP) has been reported to prevent scopolamine-induced cognitive and memory deficits. We recently indicated that LBP exerts neuroprotective effect against focal cerebral ischemic injury in mice via attenuating the mitochondrial apoptosis pathway.

Neuroprotective Effect of Matrine in Mouse Model of Vincristine-Induced Neuropathic Pain.

Chemotherapy drugs such as vincristine (VCR) can cause neuropathic pain, and there is still lack of ideal strategy to treat it. The current study was designed to investigate effect of matrine (MT) on VCR-induced neuropathic pain in animal model. VCR (75 μg/kg, i.

The Anticonvulsant and Neuroprotective Effects of Oxysophocarpine on Pilocarpine-Induced Convulsions in Adult Male Mice.

Epilepsy is one of the prevalent and major neurological disorders, and approximately one-third of the individuals with epilepsy experience seizures that do not respond well to available medications. We investigated whether oxysophocarpine (OSC) had anticonvulsant and neuroprotective property in the pilocarpine (PILO)-treated mice. Thirty minutes prior to the PILO injection, the mice were administrated with OSC (20, 40, and 80 mg/kg) once.

Neuroprotective actions of taurine on hypoxic-ischemic brain damage in neonatal rats.

Taurine is an abundant amino acid in the nervous system, which has been proved to possess antioxidation, osmoregulation and membrane stabilization. Previously it has been demonstrated that taurine exerts ischemic brain injury protective effect. This study was designed to investigate whether the protective effect of taurine has the possibility to be applied to treat neonatal hypoxic-ischemic brain damage.
