Memantine exerts functional recovery by improving BDNF and GDNF expression in 3-nitropropionic acid intoxicated mice.

Memantine (MN), a NMDA blocker is well known for its protective effect against various neurodegenerative diseases. However, its role in improving motor function and regulation of neurotrophic factors in Huntington's disease (HD) has not been studied yet. In the present study, we have investigated the effect of MN against 3-nitropropionic acid (3NP), induced motor impairment, and alterations in the expression of brain-derived neurotrophic factor (BDNF) and glial cell-derived neurotrophic factor (GDNF) in mice brain.

Telmisartan attenuates MPTP induced dopaminergic degeneration and motor dysfunction through regulation of α-synuclein and neurotrophic factors (BDNF and GDNF) expression in C57BL/6J mice.

Telmisartan (TEL), an angiotensin type 1 receptor (AT1R) antagonist, has been reported to exert neuroprotective effect in animal models of Parkinson's disease (PD). However, its effect on motor functions, mutant protein α-synuclein (SYN) and neurotrophic factors (BDNF and GDNF) expression and their interrelation in PD has not yet been elucidated. In the present study, the effect of TEL on 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induced motor dysfunctions and dopaminergic degeneration was ascertained through investigating the alterations in protein expression of dopamine transporter (DAT), tyrosine hydroxylase (TH) and SYN in C57BL/6J mouse.

Acute toxicity and the 28-day repeated dose study of a Siddha medicine Nuna Kadugu in rats.

Background: Nuna Kadugu (NK), a Siddha medicine prepared from leaves and fruits of Morinda Pubescens, used for the treatment of various skin diseases. Though NK has been widely used for several decades, no scientific report was available on its safety. Present study was undertaken to demonstrate the oral toxicity of NK in Sprague Dawley rats.

Polyphenols in madhumega chooranam, a Siddha medicine, ameliorates carbohydrate metabolism and oxidative stress in type II diabetic rats.

Ethnopharmacological Relevance: Present study was undertaken to demonstrate the mode of anti-diabetic action of a polyherbal Siddha Medicine, Madhumega chooranam (MMC).

Materials And Methods: MMC was fractionated into phenolic (PMMC) and non-phenolic (NPMMC) portions in order to identify bioactive fraction. Study was performed in type II diabetic rats.
