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 Development And Evaluation Of Novel Bionanoparticles Loaded With Nanosized Lamotrigine By Using The Novel Isolated Biopolymer From Phaseolus Vulgaris Seeds(MRI Publication Pvt. Ltd., 2020-05) Kumar, S.; Satheesh Madhav, N. V.; Verma, A.; Pathak, K.The aim of this research was to isolate and characterize the novel biopolymer from Phaseolus vulgaris seeds and to formulate lamotrigine loaded bionanoparticles using this biomaterial. The biopolymer was isolated by simplified and economical process and analysed for different physico-chemical and spectral properties. The nanosizing of lamotrigine was done by bath sonication method and its particle size in nano-range was screened by UV method. The bionanosuspension loaded with nanosized lamotrigine was prepared by bath sonication for 15 cycles (1cycle equal to 3 minutes). The formulated bionanosuspension loaded with lamotrigine using biopolymer was compared with lamotrigine loaded bionanosuspension by using HPMC. The bionanosuspension was subjected for pH study, dispersibility study, % entrapment efficiency, nanosizing screening, particle size study and in vitro study for drug release and stability study of formulated bionanosuspension. The best formulation LPVu7 showed up to 90.36 ±0.9% drug release in 36 hours. having t 50% of 17 hours and t80% of 29 hours with r2 value of 0.9927 as compared to release from LSP5 with 92.43±0.68% having t 50% of 16 hours and t80% of 28 hours with r2 value of 0.9951 in 36 hours. The results reveal that isolated biopolymer may be used as an alternative to synthetic polymer because of its novel inbuilt bioretardant cum biostabilizing properties. The formulated bionanosuspension are feasible for delivering the nanosized lamotrigine in sustained manner for prolonged time for long term treatment of epilepsy.Item Evaluation of Mass Drug Administration to Eliminate Lymphatic Filariasis in Surguja and Surajpur District, Chhattisgarh(MRI Publication Pvt. Ltd., 2022-06) Mendhe, HG; Prasad, MA; Potdar, P; Verma, A.Background: Mass Drug Administration of a single dose of DEC was launched on June 5, 2004 by the Government of India. MDA coverage increased gradually from 72.42% in 2004 to 88.96% in 2014. However, compliance has remained relatively low in most of the endemic areas as in 9 endemic Districts in State of Chhattisgarh. In Chhattisgarh State, Lymphatic Filariasis affected 14,818 people in the year 2011 and 13921 in the year 2013 with demonstrated manifestation. Objectives: To assess the coverage and compliance along with factors affecting compliance regarding MDA implementation in Surguja and Surajpur District of Chhattisgarh. Methods: A cross-sectional descriptive study was conducted from July-September 2021 in two district of Chhattisgarh. The division of segments and selection of the households was done based on the WHO criteria of coverage evaluation survey field guide in which from 30 villages, 450 households were covered. Result: The overall coverage rate was 95.55% in Surguja and 89.16% in Surajpur District. The overall compliance was 89.3% with Coverage-Compliance gap of 4.12. The Effective Coverage Rate was 89.3% in 2243 eligible population of Surguja and Surajpur District. Coverage and Compliance was found more in females as compared to males but was found to be statistically not significant. Coverage and Compliance was found more in Surguja district as compared to Surajpur district. Conclusion: Training programme for drug distributors should emphasize more on how to address the fear of side effects among beneficiaries and other reasons of low compliance for the benefit of the MDA programme.Item Expression of HER2/neu in gastric adenocarcinoma and its correlation with serum HER2/neu level and E-cadherin expression(Wolters Kluwer - Medknow, 2022-03) Pandey, I; Misra, V; Pandey, AT; Verma, A.Aim: To assess HER2/neu expressions and correlate with E-cadherin and Serum HER2 level in gastric carcinoma. Method: 31 gastric biopsies and 1 resected specimen were taken in the study with patient details and stained with H and E for histopathological details following Lauren's classification. Immunohistochemistry for HER2 and E-cadherin expression was conducted followed by serum HER2/neu ELISA. Result: Adenocarcinoma with 61% diffuse, 29% intestinal, and 10% other type were observed with predominant HER2 immunoexpression in intestinal-type than in diffuse-type adenocarcinoma. Other observations marked 44% as 3+/positive and 56% as 2+/equivocal in intestinal type while 26% cases as 3+/positive, 69% as 2+/equivocal, and 1% as 1+/negative were observed in diffuse type. The data presented 33% membranous positivity and 67% both membranous + cytoplasmic positivity in intestinal type while 2% showed membranous positivity, 47% both membranous + cytoplasmic, and 42% only cytoplasmic positivity in diffused type. On comparing the localization pattern of HER2 and E-cadherin, 25% of cases showed membranous staining while 50% of cases showed membranous with cytoplasmic staining for both. No cytoplasmic HER2 staining as well as no any staining for E-cadherin was shown by 6% cases. Conclusion: Thus, it can be concluded that cytoplasmic expression of HER2 in gastric adenocarcinoma (mainly diffuse type) may be due to shedding of its extracellular domain, leading to loss of membranous E-cadherin expression on immunohistochemistry. The loss of membranous expression of E-cadherin and increased serum HER2 ELISA were correlated well with these findings.Item A perspective on Master of Public Health (MPH) Graduates in India: Current role and way head(MRI Publication Pvt. Ltd., 2022-03) Nath, L; Mathur, M; Ali, A; Aggarwal, P; Mathur, N; Verma, A.The public health sector of any country deals on the forefront and utilizes the multidisciplinary approach. In India the Masters of Public Health graduates are trained in unstandardized manner and lack a regulatory body. The gap created in serving the unserved can easily be fulfilled by utilization of this workforce in systematic manner, The emerging competition in the field, undervalued sector in terms of monitory benefits, poor demand and limited training institutions for MPH graduates along with the contribution of MPH during COVID 19 pandemic has been emphasized in the article. The perception of those working in the field has been highlighted with the way ahead of MPH program in India.Item Phenytoin Induced Gingival Enlargement(Department of Community Medicine, Institute of Medical Sciences, Banaras Hindu University, Varanasi- 221005, India., 2022-06) Verma, A.; Choudhuri, S. R.; Choudhuri, K. R.; BS, R. P.; Chakraborty, A.; Parihar, S.Certain anticonvulsants, cyclosporine, and calcium channel blockers like amlodipine have been shown to produce clinically and histologically similar gingival enlargements in certain susceptible patients in response to local factors. These drugs appear to be similar with respect to their pharmacologic mechanism of action at the cellular level. Therefore, it is tempting to speculate that these agents may act similarly on gingival connective tissue and cause a hyperplastic response. This tissue reaction may involve a disturbance of calcium ion influx into specific cell populations with a resulting alteration in collagen metabolism and other host cell response mechanisms. A connection between ion exchange, folate uptake, collagenase activation, and bacterial inflammation may exist. The management involves Phase I therapy followed by surgical intervention. The purpose of these case reports is to highlight certain modifications in existing surgical techniques like gingivectomy, to have better aesthetic and functional outcome.
