Item Analysis Of Metformin On Endogenous Antioxidants And Oxidative Stress In Mice Brain Tissue Of Alloxan-Induced Diabetes(MRI Publication Pvt. Ltd., 2019-09) Kashyap, H.; Gupta, S.Diabetes has become a serious threat to mankind, as it is found in all parts of the world. Alloxan induced diabetic mice were treated by metformin to study the impact of oxidative stress and endogenous antioxidants. Due to the establishment of diabetes, the oxidative stress indicators were found to be positively correlated with the elevation in the levels of endogenous antioxidants. Whereas, in metformin-treated diabetic mice, the data revealed the correction of diabetes by lowering of blood glucose level along with body weight. But the levels of endogenous antioxidants were not recorded to increase except GST. It shows that under in vivo system level of oxidative stress increases due to the metformin. The data revealed that metformin treatment of mice, however, manage the glucose level but not effective in controlling oxidative stress.Item Analytical Qbd Approach For Development And Validation Of Rp-High Performance Liquid Chromatography Method For Determination Of Tofisopam In Pure Form And Tablets(MRI Publication Pvt.

Ltd., 2020-05) Pandya, H.; Patel, C. N.; Bhavsar, M.; Pandya, P. N.; Patel, S. K.; Rawal, R. M.Triple negative breast cancer (TNBC) is an aggressive breast cancer subtype that lacks hormonal receptors. This reduces the therapeutic options for TNBC patients creating more focus on chemotherapy. Drug resistance has posed as a major hurdle in treating TNBC patients. Deregulation of drug transporter proteins is one of major factors that cause resistance to chemotherapeutic drugs. In this study, ABCC6 a drug transporter protein that is found dysregulated in several resistant cancer cells has been docked with natural compounds or phytochemicals with known anti-cancer activities. Subtrifloralactone G, a withanolide extracted from Deprea subtriflora is found to show highest binding energy with ABCC6 protein. Molecular dynamics simulations further prove the stability of the ABCC6 protein- Subtrifloralactone G ligand complex. ADMET analysis shows that phytochemical Subtrifloralactone G can be used as an anti-cancer therapeutic drug in treating resistant cancer cells. The study mainly focuses on the role of phytochemicals in treating resistant TNBC cells.Item Anti-Diabetic Activity Of Few India Indigenous Medicinal Plants(MRI Publication Pvt.

Ltd., 2019-11) Talukdar, R.; Tayung, K.Eyngium foetidum L. is a medicinal plant widely used by ethnic tribal communities of Assam as an alternative source of medicine for the treatment of various diseases. The present investigation was undertaken with an aim to isolate, identify and assess the antimicrobial activity of endophytic fungi associated with the healthy leaf tissues of E. foetidum. The endophytic fungi were isolated three different media, namely, Potato Dextrose Agar (PDA), Malt Extract Agar (MEA) and Water Agar (WA) media and from three different sites. Altogether, 84 endophytic fungal isolates were isolated from 150 segments of leaf tissues. Dominant endophytes were found to be fungi belonging to the genus Colletotrichum, followed by non-sporulating members grouped under mycelia sterilia. Other fungal genera that were isolated as endophytes were Scopulariopsis, Cladosporium, Stemphylium, Penicilllium and Alternaria. The endophytic fungi thus isolated were studied for antimicrobial activity against some clinically significant human pathogenic test organisms. Ethyl acetate extracts of all endophytes exhibited antimicrobial activity by inhibiting at least one out of all the test pathogens. Amongst the isolated fungi, extracts obtained from three endophytes showed wide-spectrum activity against all the test organisms. The fungal endophytes were identified as Scopulariopsis sp., Penicillium sp. and a sterile isolate morphotype strain EF6. The study indicated that E. foetidum harbours a wide range of endophytes with antimicrobial properties and further detailed investigation of the compound present in them would lead to their potential therapeutic applications as a new source of medicine.Item Antioxidant And Antimicrobial Activity Of Different Plant Parts Of Anacardium Occidentale L.

Ltd., 2020-07) Nettilamkuzhiyil, N.Thevetia peruviana seed kernels are used for suicide attempts in many countries centuries back. The aim of the present study was to evaluate the level of toxicity exposure of seed kernels by acute and subacute studies on male wistar rats taking antioxidant enzyme levels in the vital organs like liver, kidney, heart and brain tissues myocardial marker enzyme levels in serum. Results revealed that antioxidant enzyme (SOD, GPX, GSH) levels was normal in the lower groups (25, 50 mg/kg), but drastic hike was observed in CKMB and LDH cardiac biomarker enzyme levels in 100 mg/ kg groups. In the liver tissues of group IV animals a significant dose dependent increase was observed in the activities of SOD (3.15 ± 0.58), GPx (46.55 ± 4.79) and GSH activity (18.20 ± 0.56). In kidney homogenates SOD and GSH level showed a statistically insignificant (p > 0.05) elevation, but the increase in GPx level shown by group IV animals (41.50 ± 7.04) was significant (p < 0.05) The activities of SOD in brain homogenates were increased significantly in group III (2.17 ± 0.24) and group IV (2.51 ± 0.27) animals. The GPx enzyme level also increased dose dependently (p < 0.01), but the level of GSH was found an insignificant hike. The heart, supposed to be the most adversely affected organ on cardiac glycoside administration, showed undisturbed values of enzyme levels. A noticeable elevation was observed in the serum CKMB and LDH enzyme levels in a dose dependent manner, but the extract did affect only the higher dosed animals (100 mg/kg) significantly (p < 0.05), In contrary to that, tissue homogenates of subacute animals under study showed a markedly significant hike in both CKMB and LDH levels. In conclusion, the level of toxicity and safety margin is very narrow, and the seeds really take lives of organisms, whose intake is accidentally or deliberately.Item Antipsychotic Prescribing Pattern In Elderly Patients With Psychiatric Disorders(MRI Publication Pvt. Ltd., 2019-07) Varghese, G. A.; Mansekhar, K.; Chethana, S.; Disha Rani, S.; Roop Sai, G.The elderly people are more prone to develop psychiatric disorders due to a number of factors like changes in the brain, other illnesses etc. They represent the most vulnerable group as they are most sensitive to the effects of drugs and are at increased risk of developing adverse drug reactions. This warrants the need to make the prescribers cautious about rational prescribing of antipsychotics to the Elderly. The study included elderly inpatients and outpatients visiting psychiatry ward with psychiatric disorders. Descriptive weighed analysis was performed to determine the prescribing practices of atypical antipsychotics. Among the 70 patients who were involved in the study, 36 patients were diagnosed with neurotic disorders and 30 patients were diagnosed with psychotic disorders and 4 were diagnosed with degenerative disorders (dementia). In our study neurotic disorders (51%) were the major diagnosis. 6 different atypical antipsychotic drugs were prescribed to the patients suffering from different psychiatric disorders. Among them olanzapine (43%) was the most commonly prescribed drug, followed by quetiapine (30%), risperidone (21%), clozapine (3.2%), lurasidone (1%), and aripiprazole (1%). This study has concluded that atypical antipsychotics are preferred over typical antipsychotics and Olanzapine is the most commonly prescribed drug for the elderly patients suffering from psychiatric disorders. On comparison of the prescribed daily doses with the maximum daily dose we have observed that the prescribed daily doses for the elderly patients were well within the maximum daily dose of the drugs and in our study no adverse drug reactions were reported in the study subjects that were involved.Item Application Of Central Composite Design For Citalopram Hydrogen Bromide Mouth Dissolving Films(MRI Publication Pvt.

Ltd., 2019-01) Suvarchala Reddy V, N.; Ganga Raju, M.; Alekhya, B.; Subrahmanyam, CDiabetic nephropathy has become a leading cause of end stage renal failure worldwide. To develop Complementary and Alternative Medicine for the treatment of diabetic nephropathy, the present study investigated the protective effects of methanolic extract of Bougainvillea spectabilis (MEBS) in streptozotocin-induced diabetic nephropathy. In this study, diabetes was induced by a single injection of streptozotocin (STZ, 45 mg/kg, i.p.) in rats. STZ diabetic rats were treated with oral doses of MEBS (200 and 400 mg/kg) for 8 weeks. At the end of the experimental period body, kidney weight, blood glucose levels, serum and urine parameters were investigated. Antioxidant enzymes and lipid peroxide levels were determined in the kidney along with histopathological examination of the same. MEBS significantly increased body weight, lowered blood glucose levels and ameliorated kidney hypertrophy index in the STZ-diabetic rats. The extract also decreased the levels of creatinine, blood urea nitrogen, total cholesterol, triglycerides, advanced glycation end products and albumin in serum and urine, respectively. MEBS significantly increased the antioxidant parameters in the kidney. Histological evaluation revealed that MEBS treated STZ-diabetic rats demonstrated reduced vacuolar degeneration of tubules; periodic acid Schiff base (PAS) positivity staining intensity in glomeruli and basement membrane thickening. Present findings provide experimental evidence that MEBS has potential antioxidant, antihyperglycemic and anti-glycation activities which might be helpful in slowing the progression of diabetic nephropathy.Item Bioactivity And Apoptotic Efficacy Of The Purified Terpenoid Extract From The Moss Brachythecium Buchananii (Hook.) A. Jaeger Against Mg 63 Cells(MRI Publication Pvt. Ltd., 2020-05) Greeshma, G. M.; Manoj, G. S.; Murugan, K.Bryophytes are primitive non vascular plants. A little is explored regarding the medicinal effects of bryophytes on carcinoma. This study investigated the biological effects of purified terpenoids from Brachythecium buchananii on selected cell lines such as HeLa, MDAMB-231 and MG63 human osteosarcoma cells and also elucidating the regulatory signaling pathways underlying the effects of terpenoids towards caspase cascade and the antioxidant enzyme system. The cell lines were treated with various concentrations of purified terpenoid extracts interms of evaluating viability (MTT assay). Interestingly, MG63 cell lines showed poor viability as compared to other ongo cells and was subjected to further molecular evaluations. Migration and invasion assay results using wound-healing and transwell assays, respectively reveal the pro-antimetastatic potential of the purified terpenoids from the moss. The flow cytometry study substantiated terpenoid induced apoptosis in MG63 cells. Cell cycle analysis revealed the significant increase in the number of cells arrested at the S growth phase. Terpenoid extract also displayed DNA fragmentation in the cells. Western blot analysis revealed the down regulation of the anti‑apoptotic proteins Bcl‑2, pro‑caspase 3 and over expression of the pro‑apoptotic protein Bax. In addition, the caspase cascade profile of the terpenoid extract substantiated their efficacy in tumour inhibition. Thus, the overall results confirmed the biological features of terpenoid induced apoptosis in the MG63 cells.Item Bioactivity And Dereplication Of Phenolic Compounds In Medicinal Plants(MRI Publication Pvt. Ltd., 2019-05) Lima, N.; Silveira, R.; Ramos, R.; Santos, V.; Nascimento, M.; Andrade, T.; Carli, A.; Oliveira, M.; Almeida, M.Three medicinal plants with recognized anti-inflammatory potential, identified as “erva de São João“ (Ageratum conyzoides), “Tanchagem“ (Plantago major) and “ Bardana“ (Arctium lappa L.) were obtained from a medicinal herbs company located in Teófilo Otoni city (Minas Gerais State, Brazil). The dry plant material obtained in packages was submitted to the chemical procedures to prepare the crude extracts by maceration according to the Brazilian pharmacopoeia legislation. After extraction, the samples were subjected to 1H NMR, TLC and Capillary Electrophoresis analysis by co-injection of authentic patterns of phenolic acids and flavonoids to identify the major compounds and classes of secondary metabolites present in each material and then their chemical and biological potential was assessed by DPPH free radical inhibition assay and antimicrobial against E. coli. The results obtained allow us to conclude that the phytopreparation was effective in the extraction of compounds with antioxidant potential and the three species presented a high concentration of flavonoids and other phenolics that is compatible with the chemosystematic data. The screening obtained by 1H NMR spectroscopy, TLC and Capillary Electrophoresis with ultraviolet detection analysis provided us a qualitative profile of the phytochemicals present in each material. None of the extracts were active against Escherichia coli by antibacterial disk diffusion assay at concentration of 1 mg/ml.Item Biogenic Synthesis Of Silver Nanoparticles (AgNPs) Using Celosia Cristata L. Leaves Extract And Their Antimicrobial Activity Against Otorhinolaryngological Isolated Pathogen(MRI Publication Pvt. Ltd., 2019-11) Singh, R.; Kumar, N.This work focused on the biogenic synthesis of silver nanoparticles (AgNPs) by silver nitrate using Celosia cristata leaves extract in four different solvents namely petroleum ether, acetone, methanol, and water. Silver nitrate and leaves extract were used as a precursor and capping reducing agent respectively. Biogenic AgNPs were characterized and identified by UV-Vis spectrophotometer, X-ray diffraction (XRD), Field emission scanning electron microscope (FE-SEM), and energy dispersive spectroscopy (EDX). Disc diffusion method was used for antibacterial activity of AgNPs and effective antibacterial activity was shown against IS-3, IS-4, IS-6, and IS-7 as compared to a positive control (ciprofloxacin).Item Carboxymethylation Of Karaya Gum: Application In Gastroretentive Drug Delivery For Sustained Release Of Model Drug(MRI Publication Pvt. Ltd., 2020-05) Verma, A.; Sachan, N.; Verma, A.Karaya gum (KG) is one of the least soluble of the gums. It does not dissolve in water to give a clear solution but instead absorbs water rapidly to form viscous colloidal sols. Carboxymethylation of Karaya gum is expected to improve its aqueous solubility and gelling behavior. Another objective of the research is to evaluate the potential of carboxymethylated Karaya gum (CMKG) as drug release modulator (in acidic dissolution medium) when combined with HPMC K15M based polymeric matrices bearing Propranolol HCl. In the present study, KG was carboxymethylated using Williamson Ether synthesis. FTIR spectroscopy confirmed the formation of CMKG. The prepared CMKG was used in conjunction with HPMC K15M as a polymer matrix in the formulation capsule dosage form, using Propranolol HCl as model drug. The filled capsules were then coated with Gelucire 43/01 to convert them into hydrodynamically balanced (HBS) capsule dosage form. Dextrose & fructose were also added to the drug-polymer mix as osmogen to facilitate the drug release. The degree of substitution of CMKG was found to be 0.87. HBS capsule dosage forms remained buoyant on 0.1 HCl for up to 6 hr, the buoyancy was attributed to the Gelucire 43/01 coating around the capsule shell. From the experimentation it was observed that CMKG, when mixed with HPMC K15M at 1:3 ratios, extended the release of model drug from HBS capsule dosage forms in 0.1 HCl. At CMKG: HPMC K15M ratio 2:1, release of Propranolol Hydrochloride from hydrodynamically balanced (HBS) capsules revealed fast drug release in 0.1 HCl. From the observations it is evident that KG is amenable to carboxymethylation to form CMKG. It is also evident that it is advantageous to combine CMKG with HPMC K15M as release modulator to retard the release of Propranolol HCl in acidic dissolution medium.Item Comparative Antidiabetic Potential Assessment Of Herbal Formulation Of Gymnemic Acid And Curcumin(MRI Publication Pvt. Ltd., 2019-05) Shukla, A.; Sachan, M.; Bigoniya, P.Standardization of polyherbal formulations with respect to bioactive phytocompounds is the need of the time for registration and marketing authorization in developed countries. This has prompted to prepare and evaluate a standardized bioactive phyotcompounds conintaining formulation. The study aims at development and screening of a standardized antidiabetic suspension containing active isolated phytoconstituents targeting better therapeutic effect with reduced bioburden. Suspension of isolated gymnemic acid and curcumin (GCS) was prepared, evaluated and authenticated by TLC and HPTLC. Antidiabetic efficacy of GCS was screened against alloxan induced diabetes on rats following 28 days of treatment comparative to Hyponidd tablet and Madhumehari granules. Body weight, relative organ weight, blood glucose, cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL) and very low density lipoprotein (VLDL) level was measured. The formulation having pH 6.0, refractive index 1.41 and 45.58 mg/ml total solid content showed high alcohol and water soluble extractive value. The GCS treatment normalized liver and kidney weight, decreased body weight gain, TC, TG, LDL and VLDL level along with an increase in HDL level. Study outcome signifies similar antidiabetic potential of standardized formulation GCS compared to marketed Polyherbal formulation with antihyperlipidemic activity signifying as a promising natural and safe remedy for the prevention of diabetic complications.Item Curcumin Produces Protective Effects Against Testicular Toxicity Induced By Cadmium In Albino Rats(MRI Publication Pvt. Ltd., 2019-09) Sharma, S.; Ahuja, C.The purpose of our study was to evaluate the preventive effects of supplementation with curcumin (Cur) on Cadmium (Cd) induced testicular damage. Young male Wistar albino rats were divided into five groups; Control, Cd, Cur, Cd+Cur, pre-Cur+Cd. Rats were administered an acute dose of CdCl2 at a concentration of 50 mg/kg bw and Cur at 150 mg/kg bw for 15 days. The activities of the stress indicating enzymes (SOD, CAT) and MDA content as a result of LPO along with the total tissue protein and cholesterol were assessed in the testicular homogenate of rats. A significant reduction in the activities of SOD and CAT with parallel significant upsurge in MDA accompanied by a significant reduction in total tissue protein content and a significant rise in tissue cholesterol was observed in rat testes. Also, the reduction in the testicular weights along with a decline in testosterone concentration was detected. Further, Cur supplementation with Cd significantly upturned the Cd-induced variations in oxidative stress indicating enzymes and amended the testosterone levels, total testicular protein, and cholesterol content. Therefore, it can be concluded that Cur plays a protective role against testicular toxicity produced by a single dose of CdCl2.Item Curcumin Reverses The Scopolomine-Induced Cognitive Impairment By Inos And Acetylcholinesterase Inhibition In Rodent Model Of Schizophrenia(MRI Publication Pvt. Ltd., 2020-03) Khan, H.; CHAUDHARY, A.; ALI KHAN, R.; ALI, W.Schizophrenia is a severe neuro-developmental psychiatric disorder. Curcumin is a polyphenolic compound extracted from turmeric. It is known for its antioxidant, anti-inflammatory, neuroprotective, and precognitive properties. The purpose of the current study was to evaluate the role of curcumin in scopolamine induced cognitive impairment in animal model of schizophrenia. The elevated plus-maze test was utilised to study the curcumin effect on learning and memory. Curcumin (100 mg/kg, i.p.) was administered daily for 28 days in animals. Behavioural tests such as transfer latency (TL) and spontaneous alteration behaviour was assessed after the last dose of curcumin on the 28th day, followed by biochemical estimations. Present study reported that curcumin showed anti-amnesic effect in animal models of cognitive impairment of schizophrenia. Curcumin reduced the TL compared to toxic control group (scopolamine per se) (P <0.001) in elevated plus maze. In spontaneous alteration behaviour test, curcumin significantly increased percentage alteration and possible alteration as compared to toxic control group (P <0.001). A significant change in acetyl cholinesterase activity, nitrate and oxidative parameters was observed, thus, confirming its anti acetyl cholinesterase, NOS (nitric oxide synthase) inhibition and antioxidant properties (P <0.05). The present study put forward the claim of curcumin as a new and safer therapeutic alternative for the treatment of cognitive impairment in Schizophrenia. The underlying mechanism of this potential effect may be related to anticholinesterase and nitric oxide synthase inhibition activity of curcumin. Further research is warranted for confirming the suggested pathways accountable for memory alleviating effects of curcumin in Schizophrenia.Item Design And Characterization Of Mucoadhesive Microspheres Of Etodolac(MRI Publication Pvt. Ltd., 2019-05) Shabaraya, A. R.; Parulkar, A. S.; Shripathy, D.; Shetty, PMucoadhesive microspheres are drug delivery system intended for targeting a drug to particular region. Etodolac is a Non-steroidal anti-inflammatory drug. The objective of the present work was to develop sustain release of Etodolac loaded mucoadhesive microspheres due to relatively short residence time in the GIT tract before elimination. Mucoadhesive microspheres were prepared by non-aqueous solvent evaporation method using Carbopol 974P, HPMC K100M and HPMC K4M as the polymers. Central composite design was selected for the development of the formulation. Evaluation parameters like particle size, entrapment efficiency, shape and surface morphology, degree of swelling, drug content, in-vitro drug release study and in-vitro drug release study was done. Based on the results obtained from the preliminary formulations three optimized formulations were designed. The percentage mucoadhesion and swelling index of the optimized formulation was found in the range of 66-70 % and 82.50-83.84 % respectively. Optimized formulation releases 90.94% to 92.11% of drug at the end of 10 hours and follows zero order release kinetics.
