Effect of Ayurvedic Drug on Drosophila Melanogaster

Effect of Ayurvedic Drug on drosophila MelanogasterDr. Sonali Sengupta*Namrata Sain,Lathika J,Akshay TharaliAbstract-The fruit fly drosophila melanogaster known as a model being is widely use in mammal cellular and developmental studies. Its vast genome similarity with the worlds has facilitated for various transmitted and physiological studies. Ayurvedic medication represents a traditional form of medication employ to treat various charitable illness and anomalies. This written report aims to study the resultant role of an anti-paralytic ayurvedic medicate on the physiological and behavioural pattern of motivity forged and neurophysiology defective strain of drosophila. This study will also help us to draw an analogy to the erect or action of these ayurvedic doses on human system and further lead us to better to a lower placestanding of the stipulate.Keywords- drosophila melanogaster, Ayurvedic , behavioural, physiologicalIntroduction-Drosophila melanogaster acts as an ideal species for model systems and dose fundamental fundamental interaction studies. Due to its feasibility for culturing and short reproductive cycle it is used in various factortic research prospectives. The drosophila genome on grade of its similarity with the human genome can be studied extensively to come out certain genes involved in disease condition and also concern in lowstanding the various regulatory mechanisms that are associated with it. Study of dose interaction in Drosophila can be very easily co- cereb position to its effect on populace and therefore various medicine interaction studies have been conducted in various conditions thereby relating it to the geno character reference.Drug interaction with Drosophila can be used to study its genotoxic effect as easily as any rectifying effect on the expressed pheno type of the organism. Locomotion meter and neurophysiology defective mutants of Drosophila melanogaster exhibit both structural and functional freakishness and can be considered analogus to human paralysis condition owing to the non-functioning of neurons bear on the hefts. The ebony (e11) mutants of drosophila give locomotor rhythm defect along with a defect in the electrophysiology properties of the neurons, muscles leading to the characteristic movement defect. This condition can be related to the paralytic condition in humans and dose interaction with these mutants can be used as a future way for compendium and cure of the condition in humans.Ayurveda has delineated a field of medications and formulations that have been used to treat various human abnormality conditions in India. Ayurvedic medicine represents various treated plant extracts and formulations which cease certain important compounds that target the affected sites in human inconvenience oneself conditions. These ayurvedic medicines can be considered as an example of medications which have their efficacy related to the genoptypic constitution of the subject. Various anti-paralytic ayurvedic drugs target the neuronal and muscular components of the affected condition. This paper aims at studying the effect of such an Ayurvedic drug on the travel and neurophysiology defective mutants of Drosophila melanogaster and relating it to the human complex disorder conditions.Materials and Methods-2 types of strains were used.1.Canton-SDrosophila melanogaster of Canton-S bats type strain were obtained from Dr. Kavitha Thirumurugan, VIT University. They were maintained, growd and outbred in great(p) population in optimum temperature in our laboratory.2. e11 (Dmele11tm3)The ebony e11 mutants were obtained from NCBS, Bangalore. They were cultured on corn repast sensitive maintained at 24C. The mutants showed phenotypic characteristics of locomotion rhythm and neurophysiology defective.Drug-The Ayurvedic drug used was Amukkara choorana purchased from a local ayurvedic medicine shop in Vellore in form of tablets .The main ingredient of th is medicine is Amukkara or Ashwagandha (Withania somnifera). Amukkara Choornam has an anti-arthritic activity and it is a restorative and nervine tonic.Experiment-The wild type wing were cultured in 3 types of diet- (i) corn meal forte without drug (ii) medium with 0.01g drug i.e 100microgram of drug for 100 ml.(iii) medium with 0.05g drug i.e 500microgram of drug for 100 ml. (iv) medium with 0.1g drug i.e 1000 microgram of drug for 100 ml.The e11 mutants were also cultured in corn meal medium with and without out drug of the above mentioned concentration of drug.To observe drug administration from larval give, 30 chimerical type larva were also culture in normal medium as sanitary as in medium with the above mentioned drug concentrations. The larva were transferred using a thin pigment brush and carefully planted on the medium and cultured at constant temperature.Assays-1. Survival Assay-The wild type and mutant fly were cultured in normal and drug medium for 7days (1 week) and their rate of endurance was measured.2. Climbing Assay-10 wild type and mutant locomote were discovered for their characteristic upgrade ability in normal and drug medium.3. weightlessness dainty Assay-10 wild type and mutant files from each kinfolk were exposed to a cast down source for 2-5 minutes and their anti-geotrophic behaviour was observed.4. Polytene chromosome analysis- unused type larva were dissected and polytene chromosomes were observed by acteocarmine staining for any chromosomal abberations. The larvae were collected from both normal and drug medium which were dissected with a mounted needle on a glass slide under the microscope and the polytene chromosomes were removed from the salivary glands. The polytene chromosomes were then fixed using freshly vigilant chilled fixative (Methanol Acetic acid 31) and stained with acetocarmine dye. It was then washed with diametric acetic acid,cover slip was placed . Mounting was done and observed under microscope.R ESULTS-Rate of Survival-Fig 1- Graph representing the survibility cheque of the Wild type and e11 mutant flies over a period of 7 days cultured in corn meal medium without drug and with drug at 3 different concentrations (0.01g, 0.05g and 0.1g per 100 ml)Fig 2- Wild type and e11 mutant flies cultured in corn meal medium.Climbing assay-Fig 3- e11 mutant in 0.1g drug food showing atmospheric static port (lower one)Light Sensitive Assay- The light sensitive assay was performed on Day 4-Wild type in normal food- The flies showed anti-geotropic fashion i.e attraction towards light. 8 out 10 were attracted towards lightWild type in 0.01g drug food- showed spring movement and falling cycle.Wild type in 0.05g drug food- Flies showed geotropic behavior i.e withdrawl from light source.Wild type in 0.1g drug food- Flies show complete withdrawl from light i.e they prefer to stay in dark magnetic variation in Normal food- On exposure to light it showed in general static behavior with minim al movement and difficulty in climbing due to weak muscle strength.Mutant in 0.01 drug food- Extreme static behavior and difficulty in moving.Mutant in 0.05g and 0.1g drug food- Not viable.Fig4-Wild type flies in 0.1g drug food showing withdrawl from light exposure.Polytene chromosome analysis- Polytene chromosome analysis revealed no chromosomal abberations in the wild type flies post exposure to wide-ranging concentrations of drugDISCUSSION-In the above study both wild type and ebony mutant flies were cultured in triple types of drug medium with each medium having increasing concentration of drug. both the wild type and mutant flies showed decrease in excerpt rate in food with drug concentration 0.1g as well as in 0.05g with a more potent decrease in the 0.1g indicating lethality due to the drug dose. So the drug concentration was decreased to 0.01g which showed no decrease in survival rate for the wild type flies whereas the mutant flies showed less decrease in survival rate in dicating minimal concentration of drug may induce a supportive effect on survival rate.The Climbing assay showed that the mutants in 0.1 and 0.05g drug food showed shibire behaviour and inability to cling to the wall thus inferring muscle weakness before the drug proved lethal. Whereas mutants in 0.01g drug medium showed reduced climbing pace and static movement but had a positivist effect on survival rate. Wild type flies in drug food showed no change in sign days but depicted slow climbing rate in later days. But when the drug was exposed from the larval stage, it showed a positive effect on the climbing as well as jumping behavior. Thus it can be concluded that the if the drug is exposed to the organism from the larval stage it produces a better effect as compared with crowing stage. Thus it may concluded that incorporation of the drug during the larval stage may produce a curable effect as compared to that during big(a) stage, but further studies need to be done.Light sensi tive assay revealed that wild type flies in 0.05g and 0.1g drug food showed geotropic behavior and complete withdrawl from light respectively. Mutants in drug food showed mostly static response to light.This study aims at finding out the drug interaction with the defective gene thereby drawing an analogy with the human genome. The effect of these drugs on the drosophila genome may provide an analogy as to which gene may be affected in case of patients with paralytic or muscular disorders and may also provide possible means of therapy for the anxiety and treatment of the disorders.REFERENCES-In Vivo Effects Of Traditional Ayurvedic Formulations in Drosophila melanogaster representative Relate with Therapeutic Applications by Vibha Dwivedi et.al 2012.The effects of exogenous antioxidants on life and oxidative stress resistance in Drosophila melanogaster by Tapiwanashe Magwere et.al 2006dopamine modulates acute responses to cocaine, nicotine and ethanol in Drosophila Roland J.
