Study of drug mediated effects in mice: Histology based findings

Aackground: Drugs induce numerous kinds of pharmacological effects in different body organs. For protecting organs from damage and destruction from drugs, the study of such effects is extremely important. Rapidly accumulating experimental data has opened new horizons for a comprehensive re-conceptualization of chemical modulated changes in histological features of body tissues.Methods: In this study we studied dextromethorphan, ethanol, methanol and midazolam induced changes in histological specimen from different organs in post-treated mice.Results: No pathological changes were observed in heart, liver and kidney by administering dextromethorphan at a dose of 61 mg/kg. While, ethanol causes pathological changes in heart, liver and kidney tissue at high dose i.e. 2000 mg/kg. Gross Pathological changes were observed in heart, liver and kidney by giving midazolam at a dose of 200 mg/kg.Conclusion: Dextromethorphan showed lesser side effects and is less toxic as compared with other drugs, such as, ethanol, methanol and midazolam. Lesser toxic effects were observed when drugs were administered alone, but in combination, these drugs produced higher toxic effects

Formulation and evaluation of Ketoprofen cream containing natural anti-inflammatory agent curcuma longa in treatment of rheumatoid arthritis

Non-Steroidal Anti-Inflammatory drugs have their origin as the derivatives of plants which were observed to have strong analgesic and anti-inflammatory effects in various disease states. Ketoprofen is a better tolerated NSAID because of its limited numbers of adverse effects and topical formulation has excellent permeation and absorption into the skin. The present investigation was to develop novel Ketoprofen cream formulation in combination of most effective and potent anti-inflammatory agent curcuma longa, which is reported to possess strong anti-inflammatory effects in Rheumatoid Arthritis and Osteoarthritis, according to the study by university of Arizona researchers. Combination of Ketoprofen and curcuma longa is good rational, where curcuma longa produces synergistic anti-inflammatory effects with ketoprofen. Formulation containing fixed concentrations (3%) of ketoprofen with curcuma longa was prepared. To access the efficacy of formulation stability studies, spread ability, tube extrudability, viscosity, pH, skin irritation test, in vitro drug diffusion study and anti- inflammatory effects were evaluated. The results obtained were encouraging and formulation containing Ketoprofen (3%) with curcuma longa was found better than alone Ketoprofen cream formulation

COMPARATIVE EVALUATION OF KETOPROFEN CREAM WITH DICLOFENAC AND PIROXICAM CREAM IN PATIENTS WITH RHEUMATOID ARTHRITIS DISORDERS:

Non steroidal Anti- inflammatory drugs have their origin as the derivatives of plants, which were observed to have their therapeutic effects in different disease states. They have the advantage of local action without developing central adverse effects and cognitive impairments. Side effects have been well described, although partly neglected. Topical delivery of NSAID has its therapeutic applications in management of pain and inflammation in Rheumatoid arthritis patients. Rheumatoid arthritis is a chronic systemic inflammatory disorder that may affect many tissues and organs but principally attacks the synovial joints. It can be disabling and painful condition, which can lead to substantial loss of functioning and mobility if not adequately treated. The aim of the present investigation was to compare the Ketoprofen cream with Diclofenac and Piroxicam cream in a group of volunteers suffered from Rheumatoid arthritis and to compare the efficacy of these creams in reduction of inflammation. This single blind comparative study was done to determine the efficacy, tolerability and acceptability of topical application of Ketoprofen cream (1%w/w) vs diclofenac cream (1%w/w) and piroxicam cream (0.5%w/w) in Rheumatoid arthritis patients. In this study, one hundred and twenty five volunteers suffering with acute Rheumatoid arthritis and age group between 40-70 years were analyzed for assessing the intensity of pain and anti-inflammatory effects of these three creams. The study revealed that Ketoprofen cream provides a good level of pain relief removes swelling and tenderness and improves the functional impairment, without the systemic adverse events associated with oral NSAIDs.Key Words: Cream, Diclofenac, Ketoprofen, Piroxicam, Rheumatoid arthriti

Antimicrobial and phytochemical screening of Oligochaeta ramose against different pathogenic microbes- An In vitro study

Biologically active compounds obtained from the medicinal plants are the effective chemotherapeutic agents and offering a broad spectrum of activity with greater emphasis on preventive action. The present study was aimed at evaluating the antimicrobial activities of crude methanolic extract of Oligochaeta ramose (Asteraceae) against pathogenic bacteria species of both G +ve strains (Staphylococcus aureus, Bacillus pumilus, Streptococcus pneumoniae), G -ve strains, (Escherichia coli, Citrobacter freundii, Klebsiella pneumoniae) and fungal species (Candida albicans, Aspergillus niger). In-vitro antimicrobial test was performed by disc diffusion method on nutrient agar and sabouraud dextrose agar for bacteria and fungi respectively, in order to analyze the percentage zone of inhibition and phytochemical screening was also performed. Methanolic extract showed significantly high inhibitory effect against G +ve strains, as compared to G -ve strains, whereas, no effect against C. albicans and A. niger. Modified agar well diffusion method was used to measure the minimum inhibitory concentration (MIC) and MIC values lies within the range of 75 to 150 ?g /ml for the G +ve while 300 to 600 ?g /ml for G-ve. Or.Cr was found to contain alkaloids, tannins, saponins, flavonoids and antraquinones and these agents may be responsible for antibacterial activity of this plant.

Assessment of antibacterial potential of Saccharum spontaneum Linn. (family: Poaceae), against different pathogenic microbes- an in vitro study.

In this study, Saccharum spontaneum (Family: Poaceae), was evaluated for its antibacterial potential against human pathogenic bacterial strains. In-vitro antibacterial tests were performed by disc diffusion method on nutrient agar, in order to analyze the percentage zone of inhibition. Whole plant’s extract showed the significant zone of inhibition (mm), against Staphylococcus aureus (17.00), Streptococcus pneumoniae (16.50), Bacillus cereus (15.90), Bacillus pumilus (15.45), Escherichia coli (18.00), Klebsiella pneumoniae (17.10), Pseudomonas aeruginosa (15.20) and Citrobacter freundii (14.00), with relative percentages of inhibition of 76.90, 71.60, 57.40, 56.85, 70.40, 69.90, 61.05 and 54.30 respectively. Modified agar well diffusion method was used to measure the minimum inhibitory concentration (MIC) and MIC values lies within the range of 75 to 300?g /ml for the G+ve strains while 75 to 600?g /ml for G-ve.  Due to presence of tannins and flavonoids, it inhibits the growth of bacteria on most regulatory levels such as peptidoglycan, DNA, RNA and protein synthesis

Investigations of the effect of pore size of ceramic membranes on the pilot-scale removal of oil from oil-water emulsion

Oil-water emulsions are one of the most serious pollutants because of the large quantities produced by various industries, such as the petrochemical, oil and gas industries. One of the major methods to remove oil from wastewater is filtration using ceramic tubular microfiltration membranes. However, such membranes are vulnerable to fouling, which causes operational impairment. The aims of this work are to study the influence of membrane pore size on permeate flux and oil removal efficiency at different operating parameters and the reduction in fouling when used in combination with hybrid Coagulation/sand filter-MF pre-treatment process. The droplet size of the oil-water emulsion has an interaction with the pore size of the ceramic membrane. Therefore, each pore size may be optimal, depending upon the concentration of oil in the emulsion, and hence droplet size. Steady-state flux and oil removal efficiency were found to b highest for hybrid coagulation/sand filter –MF due to a reduction of membrane fouling by reducing the oil concentration in the inlet emulsion to the ceramic membrane

PANC Study (Pancreatitis: A National Cohort Study): national cohort study examining the first 30 days from presentation of acute pancreatitis in the UK

Abstract Background Acute pancreatitis is a common, yet complex, emergency surgical presentation. Multiple guidelines exist and management can vary significantly. The aim of this first UK, multicentre, prospective cohort study was to assess the variation in management of acute pancreatitis to guide resource planning and optimize treatment. Methods All patients aged greater than or equal to 18 years presenting with acute pancreatitis, as per the Atlanta criteria, from March to April 2021 were eligible for inclusion and followed up for 30 days. Anonymized data were uploaded to a secure electronic database in line with local governance approvals. Results A total of 113 hospitals contributed data on 2580 patients, with an equal sex distribution and a mean age of 57 years. The aetiology was gallstones in 50.6 per cent, with idiopathic the next most common (22.4 per cent). In addition to the 7.6 per cent with a diagnosis of chronic pancreatitis, 20.1 per cent of patients had a previous episode of acute pancreatitis. One in 20 patients were classed as having severe pancreatitis, as per the Atlanta criteria. The overall mortality rate was 2.3 per cent at 30 days, but rose to one in three in the severe group. Predictors of death included male sex, increased age, and frailty; previous acute pancreatitis and gallstones as aetiologies were protective. Smoking status and body mass index did not affect death. Conclusion Most patients presenting with acute pancreatitis have a mild, self-limiting disease. Rates of patients with idiopathic pancreatitis are high. Recurrent attacks of pancreatitis are common, but are likely to have reduced risk of death on subsequent admissions. </jats:sec

FORMULATION DESIGN, OPTIMIZATION AND ENHANCEMENT OF SKIN PERMEATION OF IBUPROFEN CREAM BY USING OLIVE OIL AS PERMEATION ENHANCER

Non-Steroidal Anti-Inflammatory drugs have their origin as the derivatives of plants which were observed to have strong analgesic and anti-inflammatory effects in various disease states. Ibuprofen is a better tolerated NSAID because its topical formulation has limited numbers of adverse effects. The present research was conducted with the aim to develop and evaluate a novel Ibuprofen cream formulation, which would attenuate the gastrointestinal related toxicities associated with oral administration. Olive oil was used as penetration enhancer and was added in formulation to see its enhancement effect on in-vitro dug release profile. In the present study, a fixed concentration of Ibuprofen cream (2%) was prepared alone and by using olive oil as penetration enhancer. The prepared cream formulations were evaluated for several physiochemical parameters to justify its suitability for topical use. The invitro drug release was carried out by using Franz cell diffusion apparatus across the synthetic membrane. The cream formulations were evaluated for anti-inflammatory and skin irritation study. The results obtained were encouraging; Ibuprofen (2%) cream with olive oil was successfully prepared and exhibited the most satisfying results of all the parameters including a better result of in-vitro drug release as compared to Ibuprofen cream formulation without a penetration enhancer.
