The occurrence of type 2 diabetes mellitus is rapidly rising around the world’s population. India is the ‘diabetes capital of the world’ with 62.4 million Indians having type 2 diabetes. The current treatment for type 2 diabetes includes insulin and oral hypoglycemic drugs i.e. sulfonylurea derivatives, thiazolidinediones, biguanides and (alpha)-glucosidase inhibitors but these medications have most of the side effects. Wistar rats (150-200 g) were group housed (n=6) under a standard 12 h light/dark cycle and controlled conditions of temperature and humidity (25±2°C, 55–65%). The histopathological illustration showed normal acini and normal cellular population in the islets of Langerhans in the pancreas of vehicle-treated rats. Our study suggested that [10]-gingerol dose-dependently produced antidiabetic activity. In this study might be helpful to understand the role of [10]-gingerol in the clinical treatment of diabetes mellitus.","PeriodicalId":22326,"journal":{"name":"Technological Innovation in Pharmaceutical Research Vol. 10","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84630214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At 500 µg ml-1 of the test extract of P. biglobosa, there was complete killing of trypanosomes (40.±0.0 to 0.00±0.00) at 9 h of incubation, which was statistically the same as diminazine aceturate (50 µg ml-1) at 4 h.

Freshly harvested leaves sample of Ageratum houstonionum were dried under shade and powdered. Leaf sample of A. houstonionum was extracted by process of hydrodistillation using a Clevenger-type apparatus for the preparation of essential oil. Extract from A. houstonianum was prepared by dissolving 5 µL of the essential oil in 10 mL methanol. All the sample was filtered through a Whatman (Maidstone, England) stainless steel syringe assembly using a 0.22 µm Durapore (Millipore: Milford, USA) membrane filter. Purification processes via column chromatography, thin layer chromatography and preparative thin layer chromatography were done. Reverse phase HPLC analysis was carried out via a Waters HPLC system consisting of model 510 and 515 pumps, a Rheodyne injector, a Novapak C18 column (250 x 4.6 mm i.d.; 4 µm), a model 490E multi-channel detector and Millennium 2010 sata manager.

In the present investigation, we studied the impact of one of the AAS compounds 17(alpha)-methyltestosterone on acethylcholinesterase (AChE) enzyme activity in different parts of mice brain viz. forebrain, hippocampus, midbrain, and hindbrain. \u0000Methods: The adult female mice were assigned to four experimental groups to which different doses of 17(alpha)-Methyltestosterone (17(alpha)-MT- 0.5, 5.0 and 7.5 mg/kg bwt, respectively) were administrated s.c. for 30 days. \u0000Results: A significant increase in AChE activity in forebrain and midbrain (low and medium dose treatment) suggests a reduction of cholinergic neurotransmission efficiency due to a decrease in acetylcholine levels in the trans-synaptic cleft. Further, a concurrent reduction in AChE activity was observed in the whole brain, hippocampus and hindbrain of 17(alpha)-MT treated mice suggest the impairment in neuronal transmission. Since the regulation of cholinergic system through acetylcholine hydrolysis has been largely attributed to AChE activity, a significant reduction in its activity may lead to stress-related anxiety, memory loss with some cognitive and behavioral aspects in the mice. \u0000Conclusion: Based on the observed results we propose that 17(alpha)-MT an alkylated steroid compound has a negative impact on AChE enzyme activity in different parts of mice brain leading to impairment in neuronal transmission.","PeriodicalId":22326,"journal":{"name":"Technological Innovation in Pharmaceutical Research Vol. 10","volume":"103 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78448473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nair, Aniruddha Gurchal, Sujay Kanitkar","doi":"10.9734/bpi/tipr/v10/11504d","DOIUrl":"https://doi.org/10.9734/bpi/tipr/v10/11504d","url":null,"abstract":"Since discovering new chemical entities is a complex, expensive, and time-consuming process, current trends have shifted toward designing and developing improved drug delivery methods for existing drugs. Recent times, fast dissolving oral films were introduced to the market, attracting the attention of a large number of pharmaceutical companies due to their numerous advantages over other oral dosage forms, including ease of administration, better patient compliance, rapid drug absorption, and rapid onset of action with instant bioavailability. Aside from these advantages, quick dissolving oral films can be employed in children, the geriatric, and bedridden patients who have difficulties swallowing tablets or capsules. Initially, fast-dissolving oral films of breath strips, confectionary, and oral care treatments were developed, but it has now evolved into an innovative and widely accepted technique for delivering both OTC and prescription drugs.  Fast dissolving films are gaining interest as an alternative to fast dissolving tablets. The films are designed to disintegrate in a matter of seconds when they come into touch with a wet surface, such as the tongue, allowing the user to eat the food without the need for extra liquid. This ease of use gives a marketing benefit as well as greater patient compliance. Since the medicine is absorbed straight into the systemic circulation, it avoids gastrointestinal degradation and the first-pass impact.Solvent casting is used to make the Loperamide hydrochloride mouth dissolving film. The ingredient used for formulation Loperamide hydrochloride as a Anti-Diarrheal, HPMC-E50, HPMC-E15-LV and PVA as film forming polymer, propylene glycol as a plasticizer, Sodium starch glycolate (2-8%) as super disintegrant, lemon oil (2-5%) as a flavoring agent, citric acid (2-6%) as a Saliva Stimulating Agent, methylparaben (0.015%) as a preservative. Tensile strength, disintegration time, and percentage drug dissolution were chosen as independent variables, whereas tensile strength, disintegration time, and percentage drug dissolution were chosen as response variables. Mass uniformity, thickness, percent drug content, folding endurance, surface pH, moisture uptake, % swelling, percentage elongation, tensile strength, in vitro disintegration time, and in vitro percentage drug dissolution were all considered when evaluating the formulations. Loperamide was discovered to be a viable candidate for development of Fast Mouth Dissolving Films. The solvent casting procedure used to create Loperamide oral films is simple and cost-effective. It was deemed acceptable by the super disintegrants who were used in this study. FT-IR tests of drug-excipient compatibility indicated no physicochemical interaction. The obtained oral films were clear, had sufficient physical strength, and had a suitable disintegration time. In vitro dissolution experiments of all formulations revealed a superior release profile than pure medicines.Based on the ","PeriodicalId":22326,"journal":{"name":"Technological Innovation in Pharmaceutical Research Vol. 10","volume":"95 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83523083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
