RESUMO

Anxiolytic effect of ethanol, hexane extracts and pure compounds ß- sito sterol glucoside and bergenin isolated from Adenanthera pavonina AP (Fabaceae) and Peltophorum pterocarpum PP (Fabaceae) leaves were monitored in this study. Mice were treated with dose of 125mg/kg body weight of ethanol and hexane leaves extracts of both tested plants while, 5mg/kg body weight of ß-sito sterol glucoside and 25mg/kg body weight of bergenin. The effect was monitored by hole board test, forced swimming test, open field apparatus and stationary rod test. Results from neuropharmacological effects revealed that ethanol extract of AP leaves and hexane extract of PP leaves had significant anxiolytic (forced swimming test) exploratory (head dip and open field test) and neuro activator activity (stationary rod test) at tested dose. The greatest anti-depressant and anxiolytic effect was found in ethanol extract of AP leaves when compared to all treated drugs. A part from memory enhancing effects, diazepam treated mice also exhibited anxiolytic and antidepressant effects and found comparable with ethanol extract of AP. These findings may clarify the impact of ethanol, hexane extracts and pure substances ß-sitosterol glucoside and bergenin at tested concentrations, as well as their potential to treat the Parkinson's and related disorders as an alternative therapy.

RESUMO

To explore complex biological and chemical systems, pharmaceutical research has effectively included several molecular modeling tools into a range of drug development initiatives. Molecular docking methods are widely employed in current drug design to investigate ligand conformations within macromolecular targets' binding sites. This method also estimates the ligand-receptor binding free energy by assessing critical phenomena involved in the intermolecular recognition process. In an attempt, several natural products have been synthesized in our laboratory. All the synthesized compounds containing (6H-Dibenzo[b,d]pyran-6-one) framework were subjected to molecular docking studies for the inhibition of CYP1B1 and BCL2 proteins using Auto Dock Vina software and the interacting amino acid residues were visualized using Discovery Studio, to look into the binding modalities that might influence their anticancer properties. The in silico molecular docking study outcomes showed that all the synthesized compounds having optimum binding energy and have a decent affinity to the active pocket, thus, they may be considered as a respectable inhibitor of CYP1B1 and BCL2 proteins.

RESUMO

Among respiratory complications, cough is an important defensive pulmonary reflex that removes fluids, irritants or foreign substances from the respiratory tract. Rosa damascene Mill, petal extract is a traditional medicine and reported to use in the management of cough. In the present study rose petals extract samples were used to prepare natural antitussive cough syrups containing ivy leaf extract to observe synergistic effect of rose water in managing coughing in rats. Four cough formulations (A1, A2, A3 and A4) were prepared. The antitussive activity was observed at three dosage levels; 5ml, 10ml and 15ml. Cough was induced by the standard procedure using sulfur dioxide gas and ammonia. The antitussive activity was recorded by observing the coughing bouts. The result indicated that all formulations had a good effect on cough reduction at 90min but comparing the effect of formulations in all doses formulations, A2 followed by A3 and A4 at 30 minute time interval which is good in comparison with standard Diphenhydramine HCL and Dextromethorphan HBr 10ml in sulfur dioxide gas and ammonia induced cough. Hence, the results of the present study indicated the synergistic effect of rose water in the management of cough ailments.

RESUMO

Frequent use of antibiotics has been developed resistance and the use of broad spectrum cephalosporin must be limited in children. The study evaluated the association of prescribing patterns of third generation cephalosporin with diagnosis, age, availability of cultural sensitivity report and gender. It is an observational study that was carried out in the duration of six months in a low socio-economic tertiary care hospital. The data of six hundred and eighty-five (685) patients were collected from the medical records of the tertiary hospital. The cephalosporin are the most prescribed antibiotics in children 118/217 (54.3%) followed by adults 119/403 (29.5%) and teenagers 18/65 (27.6%). Whereas, 75/217 (34.5%), 126/403 (31.2%) and 22/65 (33.8%) were prescribed cephalosporin with combination in patients respectively. The culture sensitivity was performed only in 25% of patients i.e., 173/685, Of 173 culture reports 70 and 91 cases from children and adults respectively. Blood is mostly examined specimen in children and urine in adults. Escherichia coli was highly recovered pathogen in culture sensitivity report. The study concluded broad spectrum cephalosporin antibiotics were highly prescribed in children. The culture sensitivity was performed in limited number of patients. Antibiotics stewardship programme will be implemented to reduce the prescribing of broad spectrum cephalosporin in young patients.
