India is a land of medicinal flora, there are large numbers of plants with miraculous medicinal values has been used traditionally to cure several diseases from decades in Ayurveda. So the present study was designated to evaluate the antimicrobial activities of Aegle marmelos (bale) bark extracts. In this study different bark extracts were prepared using various solvents, further these extracts were analyzed against selected microbial strains like Escherichia coli (MTCC-443), Bacillus subtilis (MTCC-441), Pseudomonas aeruginosa (MTCC-4673), Staphylococcus aureus (MTCC-3160), Aspergillus brasiliensis (MTCC-1344) and Candida albicans (MTCC-227) by agar well diffusion method and determination MIC by broth dilution method. The extracts showed a broad spectrum of antimicrobial activities by inhibiting the growth of respective microorganism in agar well diffusion assay. Extracts of acetone and ethanol 70% showed highest activity against Escherichia coli whereas methanol and choloroform extracts showed significant activity against Bacillus subtilis. The present study supports the immense medicinal properties of Aegle marmelos bark. The study may be insight for future researches in area of new drug development of...

Alzheimer’s disease (AD) is a progressive and irreversible neurodegenerative disorder leading to dementia in the elderly inhabitants. Increasing evidence advises that oxidative stress that is normally associated with aging is an obvious and early feature of AD and plays a role in its pathogenesis. The present study was designed to evaluate the possible neuroprotective activity of Ginkgo biloba (Gb) and / or Peganum harmala (Ph) extract against AD in a rat model. AD was induced by chronic administration intraperitoneal injection of scopolamine (0.7 mg kg-1, i.p.) to rats for a period of 7 days. The Gb (120 mg/kg b.wt.) and Ph (187.5 mg/kg b.wt.) were administrated to AD rat group orally daily for a period of 30 days. The results revealed that the levels of thiobarbituric acid reactive substances and Xanthine oxidase were significantly increased, even though the activities of superoxide dismutase and catalase, as well as the reduced glutathione, were significantly decreased in the brain homogenate of Alzheimer group. Additionally, brain acetylcholinesterase as well as alkaline phosphatase, acid...

Propionibacterium acnes is one of the bacteria that causes acne. One of the natural ingredients that potentially as anti acne is kefir. Kefir is a product of fermented milk with starter kefir grain. The fermented kefir is incorporated into the gel product for acne treatment. The purpose of this study was to formulate the fermented kefir in the gel product and to test the antibacterial activity against Propionibacterium acnes. Fermentation in cow’s milk, goat’s milk, and soy milk using starter of kefir grain with concentrations of 2%, 5%, and 7% in each type of milk. One best base formula is added to fermented kefir. Evaluation of the preparation includes organoleptic, homogeneity, dispersion, pH, viscosity at room temperature, accelerated stability test, antibacterial activity test, and panelist test. The best gel base is FT3 with Viscolam® MAC 10 concentration of 8%. The concentration of fermented kefir from cow’s milk, goat’s milk, and soy milk is incorporated into gel products, i.e. 5%, 7%, and 2%, respectively. Stable gel based on organoleptic observation...

Background: The limited evidence of the critical role of clinical pharmacists in Egyptian teaching hospitals led to the fact that critical care pharmacists’ responsibilities are still focused on dispensing and drug distribution. Objective: Assess the important role of clinical pharmacy service activities in an Egyptian intensive care unit (ICU) by describing the impact of medication errors on clinical outcome of critically ill-patients with renal insufficiency. Methods: An observational retrospective cohort study was carried out over a five months period on patients admitted to ICU with estimated creatinine clearance (CrCl) less than 50 ml/min on admission and known to have chronic kidney disease (CKD). Patient records, physician orders, pharmacy and nursing notes of 69 patients were collected and reviewed by a clinical pharmacist. Medication errors were assessed. Main outcome measure was Length of ICU stay and mortality. Results: One hundred and seventeen MEs were identified; prescribing errors (58.9%), wrong administration technique (17.9%), drug-preparation errors (11.9%) and monitoring errors (11.1%). Errors in renal dose adjustment were the most frequent prescribing errors...

The purpose of this study was to improve the dissolution rate of poorly soluble Nicardipine hydrochloride with cyclodextrin complexation by using different techniques like physical mixing, solvent evaporation and kneading method. Nicardipine hydrochloride is a calcium channel blocker. It is belonging to BCS class – II having poor solubility and high permeability. It is used to treat Angina having low bioavaibility about 10 – 40% orally is attributed to the hepatic first pass metabolism. The present invention relates to the inclusion complex made by β-Cyclodextrins and the methods for enhancing the bioavailability of Nicardipine hydrochloride. Solid inclusion complexes were prepared by conventional methods like physical mixing, solvent evaporation and kneading techniques. Optimized complex was characterized by using powder X-ray diffractometer and FTIR. Ex-vivo studies showed that the dissolution rate of Nicardipine hydrochloride was significantly improved by the complexation with β-cyclodextrin with respect to the drug alone. Physical mixing method showed highest dissolution rate than the other...
