Brief resume of the intended work: 6.1 Need for the study: Parkinson’s disease (PD) is the most common form of a group of progressive neurodegenerative disorders characterized by bradykinesia, rest tremor, muscular rigidity, shuffling gait, and flexed posture1. Most of these features match with the Ayurvedic description of the disease KAMPAVATA2, 3.Worldwide incidence of PD is estimated to be around 7 to 10 million4. Its peak age of onset is in the early 60s1, progressively debilitating the affected individual. Current drug therapies for human PD with Levodopa or various dopamine receptor agonists offer symptomatic relief and appear to have little effect on the neurodegenerative process5. More than 50% of patients with PD treated over 5 years with Levodopa will develop complications such as motor fluctuations and dyskinesia’s. In this scenario, slowing the progression of PD through neuroprotective or restorative therapy is a major focus of research. From a pharmacologic standpoint, current strategies involve interrupting the cascade of biochemical events that leads to death of dopaminergic cells 1.Hence, the current study aims at finding such an activity in an herb INDRAVARUNI – Citrullus colocynthis Schard (which is prescribed in a classical Ayurvedic text for the management of KAMPAVATA6) using ROTENONE induced PD animal model7, 8. A Similar work has already been taken up to screen the antiparkinson’s activity of INDRAVARUNI (Citrullus colocynthis), wherein OXOTREMORINE is used to induce Parkinsonism in mice.Oxotremorine being a non-selective muscarinic acetylcholine receptor agonist produces temporary extrapyramidal signs mimicking Parkinsonism9 -like tremor, ataxia and spasticity; which are antagonized by anticholinergic drugs10.However, the tremor induced by such cholinergic agonists resembled more a condition of cholinergic intoxication than parkinsonian tremor11. Hence, the antagonism of oxotremorine induced tremor can be more suitably used to investigate the central antimuscarinic effect of a drug12. 6.2 Review of Literature: In Charaka Samhita Vepathu has been described as one of the eighty types of Vataja nanatmaja vyadhi. The term KAMPAVATA was explained for the first time in the text Basavarajeeyam3, with most of its clinical features similar to that of PD. The main clinical feature of Kampavata is KAMPA2, 3 (Tremor), wherein Tremor is particularly important in diagnosing PD, as it is present in 85% of patients with true PD1.Also as explained in the text, Basavarajeeyam3 few more features of Kampavata can be compared with that of PD; Karapadatale kampa – Tremors in the hands and feet. Dehabhramana – Postural instability. Although PD defined clinically as a movement disorder, it is now widely appreciated that PD can be accompanied by a variety of non-motor symptoms, including autonomic, sensory, sleep, cognitive, and psychiatric disturbances1. These non-motor features can also be related with Ayurvedic description on Kampavata as given in the text Basavarajeeyam3; Nidrabhanga – sleep disturbances Matiksheena – Dementia Parkinson’s disease as such is characterized by loss of ∼50–70% of the dopaminergic neurons in the substantia nigra pars compacta (SNc), a profound loss of dopamine(DA) in the striatum, and the presence of intracytoplasmic inclusions called Lewy bodies (LB), which are composed mainly of α-synuclein and ubiquitin13. 4 Oxidative stress appears to play an important role in the sporadic forms of PD. Endogenous sources of oxidative stress include the free radicals produced by the metabolism of dopamine and melanin. Additional stress may come from defects in mitochondrial complex I of the oxidative phosphorylation chain. Other contributors to the selective dopamine neuron degeneration in PD are abnormal phosphorylation of proteins, microglial activation, low-grade inflammation, and apoptosis; each represents a potential target for therapeutic intervention1. Varunitailawhich is prepared using the root of Indravarunihas been indicated in Kampavata6. Indravaruni(Citrullus colocynthis) is a perennial, scabrid, prostrate or climbing herb with angular stems and bified tendrils14. It has Tikta rasa; laghu, ruksha, tikshna guna; Ushna virya; katu vipaka; is kaphapittahara, rechaka & garbhapataka; is indicated in udararoga, gulma, kosthabaddhata, plihodara, krimi, kamala, sandhivata, amadosa, unmada & apasmara14.

To compare the efficacy of VARUNITAILA in KAMPAVATA (PD) with standard drug and vehicle control groups. 7. Materials and Methods 7.1 Source of Data 1. Literary source: The literary aspect will be reviewed and data will be collected from authentic classical Ayurvedic literatures, modern texts, recent medical journals, internet and other available sources. 2. Source of drug: Genuine, botanically identified Indravaruni moola will be collected from its natural habitat. 3. Preparation: Varunitaila will be prepared as per the classical reference using Indravaruni moola and Tila taila6. 4. Experimental source: Standard antiparkinsonian drug (L-Dopa) will be procured from recognized pharmaceutical laboratory. Healthy male Albino rats of middle age group will be selected for the experiment and maintained in the animal house under standard conditions8, 7. The Parkinson inducing drug rotenone and other chemicals& reagents required for the study will be procured from authentic sources. 5. Place of work: - Dept. of Dravya Guna, JSS Ayurveda medical college, Mysore and JSS Medical College, Mysore / DFRL, Mysore. 7.2 Method:A. Study design: Sample - 42male Albino rats of middle aged group will be selected for the study and will be separated randomly into 7groups of 6 animals in each. Considering the 10% mortality associated with neurotoxic model7 each group will be added with an extra animal. 6 Sl. No Groups No. of Rats Inducing PD Study 1 Normal Control 06+01 Not treated 2 Negative Control 06+01 Rotenone with vehicle Not treated 3 Standard Treated 06+01 Rotenone with vehicle Standard dose of L-Dopa 4 Test group A 06+01 Rotenone with vehicle Varunitaila OD dose 5 Test group B 06+01 Rotenone with vehicle Varunitaila Bid dose 6 Test group C 06+01 Rotenone with vehicle Varunitaila Tds dose 7 Vehicle Control 06+01 Rotenone with vehicle Tila Taila Only vehicle Each group will be housed in a separate rectangular polypropylene cage and the cages will be provided with dust free paddy husk as a bedding material. The animals will be housed in a controlled conditions of temperature (25 ± 30 C), humidity (50 ± 5%) with a 12h light/dark cycle. They will be maintained on a pellet diet and tap water. Dose – Test drug (Varuni taila): 0.9ml/kg body wt6, 15. Standard drug (L-dopa): 10mg/kg body wt/day16. Mode of administration - orally. Duration of the treatment – Treatment shall be continued till the animals develop debilitating phenotype / till 11th day 8(whichever occurs first). Preparation of Rotenone solution – Rotenone solution will be prepared as a stock for 3 days in 100% Dimethylsulfoxide (DMSO) and diluted in medium chain triglyceride, Miglyol 812N to obtain a final concentration of 3mg/ml rotenone in 98% Miglyol 812N & 2% DMSO. Vortexing the solution creates a stable emulsion of the DMSO containing rotenone &Miglyol 812N. Fresh stock solution will be prepared twice a week and stored in a vial protected from light. Vortexing of the vial several times before each injection will be ensured to eliminate the possibility of settling7. Schedule of the procedure – Before inducing PD, the experimental animals will be acclimatized for three days and will be assessed for their motor and behavioral scores. The Rotenone solution thus prepared will be administered at 1ml/kg body weight/day intraperitoneally to all the groups till 9th day8, except for the normal control group which receives only the vehicle (DMSO+Miglyol 812N)7. 7 The respective treatment groups will receive their treatment from the day of starting of rotenone injection8. During daily handling, animals will be observed for the emergence of PD phenotype7, 8. The animals will be assessed for their motor and behavioral scores on day 6, day 97 and day 118. The trial and standard drug treatment will be continued till the animals develop debilitating phenotype or till the 11th day8. Animals developing debilitating phenotype – limiting their mobility, feeding or grooming; will be sacrificed and brain samples will be procured from them for further analysis7. Sample collection Terminally, rats will be sacrificed and brain samples shall be obtained from all the groups7, 8. B. Assessment criteria: Motor& Behavioral assessment a) Open field test 17, 18 b) Pole test19 c) Rearing behavior20, 21 d) Postural instability test22 e) Rotarod test23, 24 f) Tail suspension test25 Time taken for the development of debilitating PD phenotype7.
