In the present study, we evaluated anti-Parkinson’s activity of petroleum ether extract ofFicus religiosa(PEFRE) leaves in haloperidol and 6 hydroxydopamine (6-OHDA) induced experimental animal models. In this study, effects ofFicus religiosa(100, 200, and 400 mg/kg, p.o.) were studied using in vivo behavioral parameters like catalepsy, muscle rigidity, and locomotor activity and its effects on neurochemical parameters (MDA, CAT, SOD, and GSH) in rats. The experiment was designed by giving haloperidol to induce catalepsy and 6-OHDA to induce Parkinson’s disease-like symptoms. The increased cataleptic scores (induced by haloperidol) were significantly (p<0.001) found to be reduced, with the PEFRE at a dose of 200 and 400 mg/kg (p.o.). 6-OHDA significantly induced motor dysfunction (muscle rigidity and hypolocomotion). 6-OHDA administration showed significant increase in lipid peroxidation level and depleted superoxide dismutase, catalase, and reduced glutathione level. Daily administration of PEFRE (400 mg/kg) significantly improved motor performance and also significantly attenuated oxidative damage. Thus, the study proved thatFicus religiosatreatment significantly attenuated the motor defects and also protected the brain from oxidative stress.

Objective: The current study evaluates anti-Parkinson’s activity of aqueous extracts of leaves of Murraya koenigii (MK) (AEMK) against paraquat (PQ)-induced Parkinsonism in rats. Methods: In this study, effects of MK (100, 200, and 400 mg/kg, p.o.) were studied using in vivo behavioral parameters such as catalepsy, muscle rigidity, and locomotor activity and its effects on neurochemical parameters malondialdehyde, catalase (CAT), glutathione (GSH) reductase, GSH peroxidase, and GSH in rats. Results: Parkinson’s disease was induced by administering PQ 10 mg/kg b.w/i.p once in a week for 4 weeks. The increased cataleptic scores were significantly (p<0.001) found to be reduced, with the AEMK in a dose-dependent manner. Chronic administration of PQ significantly induced motor dysfunction (muscle rigidity and hypolocomotion), showed a significant increase in lipid peroxidation level, and depleted the levels of GSH, CAT, and reduced GSH. Daily administration of AEMK significantly improved motor performance and also significantly attenuated oxidative damage. Conclusion: The study proved that MK treatment significantly attenuated motor defects and also protected the brain from oxidative stress.

Background: The fruits with the seeds of Dracunculus vulgaris Schott. (Araceae) are used against inflammatory diseases in Turkey. Objective: Present study was designed to justify this folkloric usage type of the plant. Therefore, the aim of this study is to investigate the anti-inflammatory activity of D. vulgaris. Methods: Petroleum ether, ethyl acetate and methanol extracts were prepared from the fruits, successively. Carrageenan-, serotonin-, and prostaglandin E2-induced hind paw edema; acetic acid–induced capillary permeability and 12-O-tetradecanoyl-phorbol-13-acetate–induced mouse ear edema models were used to assess the antiinflammatory activity of the extracts. The analgesic activity was experienced by using p-benzoquinone-induced abdominal constriction test. Results: The petroleum ether extract displayed the highest activities in all of the used test models compared with the control group. Therefore, the constituents of this extract were determined by using gas chromatography–mass spectroscopy (GC–MS). Linoleic acid was found to be major constituent of the petroleum ether extract of D. vulgaris. Conclusion: This study has provided some justification for the folkloric use of the plant.

Numerous studies have suggested that alpha-synuclein plays a prominent role in both familial and idiopathic Parkinson's disease (PD). Mice in which human alpha-synuclein is overexpressed (ASO) display progressive motor deficits and many nonmotor features of PD. However, it is unclear what in vivo pathophysiological mechanisms drive these motor deficits. It is also unknown whether previously proposed pathophysiological features (i.e., increased beta oscillations, bursting, and synchronization) described in toxin-based, nigrostriatal dopamine-depletion models are also present in ASO mice. To address these issues, we first confirmed that 5- to 6-mo-old ASO mice have robust motor dysfunction, despite the absence of significant nigrostriatal dopamine degeneration. In the same animals, we then recorded simultaneous single units and local field potentials (LFPs) in the substantia nigra pars reticulata (SNpr), the main basal ganglia output nucleus, and one of its main thalamic targets, the ventromedial nucleus, as well as LFPs in the primary motor cortex in anesthetized ASO mice and their age-matched, wild-type littermates. Neural activity was examined during slow wave activity and desynchronized cortical states, as previously described in 6-hydroxydopamine-lesioned rats. In contrast to toxin-based models, we found a small decrease, rather than an increase, in beta oscillations in the desynchronized state. Similarly, synchronized burst firing of nigral neurons observed in toxin-based models was not observed in ASO mice. Instead, we found more subtle changes in pauses of SNpr firing compared with wild-type control mice. Our results suggest that the pathophysiology underlying motor dysfunction in ASO mice is distinctly different from striatal dopamine-depletion models of parkinsonism.

Aims: The present investigation was aimed at exploring the phytoconstituents using Gas Chromatography Mass Spectroscopy and to evaluate antioxidant and anti-inflammatory properties of the leaf extracts. Materials and Methods: The extracts were obtained sequentially with petroleum ether, ethyl acetate and water using soxhlet apparatus. The anti-inflammatory property of the identified compounds using GC- MS spectroscopy was evaluated in silico. The antioxidant activity was performed by DPPH and H2O2 method whereas anti-inflammatory study was carried out by HRBC membrane stabilization method. Terpenoids were found to be major constituents in petroleum ether extract while, phenols and flavonoids were predominantly found in ethyl acetate extract. Results and Discussion: The GC-MS analysis of the extract revealed six major molecules including Squalene, 19β, 28- epoxyleanan-3-ol and 2-tu-Butyl-5-chloromethyl-3-methyl-4-oxoimidazolidine-1-carboxylic acid. The ethyl acetate extract showed a significant antioxidant activity (P<0.01) in both DPPH method (70.87 %) and H2O2 method (73.58%) at 200 µg mL-1 . Increased membrane stabilization of petroleum ether extract was observed in the in vitro anti-inflammatory activity study. A strong relationship between the terpenoid content and anti-inflammatory activity was obtained from the correlation (0.971) and docking study. Conclusion: These results justify T. involucrata to be a rich source of terpenoids with potent antiinflammatory property.

In present investigation was carried out to screening of hair growth promoting potentiality of petroleum ether extract of Abrus precatorius leaf. Preliminary chemical tests and TLC analysis revealed the presence flavonoids and saponins. Hair growth promoting activity of petroleum ether of Abrus precatorius was screened by considering different parameters which included time taken for covering bald patch, length of hair produced, percentage of hair follicles in anagen and telogen phases, time of hair growth initiation and completion and level of minerals in blood. The petroleum ether extract of Abrus precatorius showed a very good hair growth promoting activity at a dose of 300 mg/kg which was comparable to that of 2% minoxidil. After 30 days of treatment with test and standard drugs it was observed that, time taken for covering the bald patch, hair growth initiation and completion time and quantitative hair growth were found to be comparable to that of the standard drug. An increase in percentage of hair follicles turning from telogen phase to anagen phase was noted. The control treated group of animals showed poor hair growth for all the parameters. Keywords: Abrus precatorius Linn, Anagen, Catagen, Telogen, Minoxidil
