Two medicinal plants (Khaya senegalensis and Melia azedarach), frequently used by a large part of the Senegalese population and in particular that of the natural region of Casamance in the traditional treatment of malaria, were selected to study phytochemistry and to compare the antimalarial activity of the different parts used (leaves, bark, and seeds). The extraction of these drugs was carried out successively following a gradient of increasing polarity with cyclohexane, ethyl acetate, dichloromethane, and methanol. In-vitro anti-plasmodial screening of the different fractions was performed on chloroquine-sensitive and chloroquine – resistant strains of Plasmodium falciparum (3D7 strain and W2 strain, respectively). The MDEK fraction is the most active on 3D7 strain with an IC50 = 1.81 ± 0.53 μg / ml (Selectivity index > 55.25). In-vitro cytotoxicity assays on human umbilical vein endothelial cells (HUVEC cells) were performed and the selectivity index was calculated. These tests reveal the non-toxicity of the fractions tested with high CC50 and very often greater than 100 μg /...

Aim: To assess whether Tranexamic acid has any effect in inhibiting degradability of PRF membrane and also to compare the degradability of PRF at different concentrations of Tranexamic acid (200 mg, 150 mg and 50 mg). Material and Methods: The degradability of PRF membrane was compared between various concentrations of Tranexamic acid such as 200 mg, 150 mg, 50 mg against negative control of phosphate buffer solution (PBS). Group 1-PBS (negative control) n = 5, Group 2-PBS containing 200 mg of Tranexamic acid n = 5, Group 3-PBS containing 150 mg of Tranexamic acid n = 5, and Group 4-PBS containing 50 mg of Tranexamic acid n =5. PRF procured from each donor was weighed in a micro weighing machine and they were later dropped in each of the 4 groups of eppendorfs (5 in each group). After 1 week of storing in room temperature, the PRF pieces were retrieved and percentage of remaining PRF was calculated. ANOVA and post hoc tests were used to statistically compared this data...

Background: Dashamoola is a group of ten drugs i.e. Bilva (Aegle marmelos (L.) Corrêa), Patala (Stereospermum suaveolens (Roxb.) DC.), Agnimantha (Clerodendrum phlomidis L.f.), Shyonaka (Oroxylum indicum (L.) Benth. ex Kurz), Gambhari (Gmelina arborea Roxb.), Bruhati (Solanum nigrum L.), Gokshura (Tribulus terrestris L.), Kantakari (Solanum xanthocarpum Schrad. & H. Wendl.), Prishniparni (Uraria picta (Jacq.) DC.), Shalaparni (Desmodium gangeticum (L.) DC.) part used are moola of all the drugs. Dashamoola kwatha choorna is made use for parisheka in the management of spastic cerebral palsy in children. Aim: To standardize Dashamoola kwatha choorna. Materials and Methods: Physico-chemical studies like Loss on drying, acid insoluble ash, total ash, water soluble ash, alcohol soluble extractive, water soluble extractive and HPTLC were carried out as per the WHO guidelines, Indian Pharmacopoeia and Ayurvedic Pharmacopoeia. Conclusion: Standar-dization tests done on Dashamoola kwatha choorna helped in authenticating and ensuring the quality of the...

Objective: To detect the prevalence of Plasmid resistant AmpC β-lactamases gene in clinical isolates of gram negative organisms from UTI patients which produce resistance against multiple antibiotics. The gene coding for AmpC β-lactamases is also present in E. coli & Klebsiella species was not expressed because due to lack of promoter region, but the transfer of chromosomal genes to plasmids allows the expression of AmpC β-lactamases that hydrolyze the β-lactam ring, which has greater impact on resistance against multi-drug antibiotics, is a significant problem around the world. Methods: Among 20 non-repetitive clinical isolate of each Escherichia coli and Klebsiella pneumoniae, examined for identification and characterization of urine cultures based on morphological, biochemical tests, antibiotic resistant pattern, modified-disc method and detection of AmpC gene by plasmid identification by agarose gel electrophoresis and amplification of AmpC gene by PCR techniques. Results: The study detects the prevalence of AmpC gene primarily by modified disc inducer method as well as conformational molecular analysis by PCR amplification techniques. AmpC prevalence was observed in both...

Objective: Pyrostegia venusta (Ker Gawl.) Miers, Bignoniaceae, is native to the Brazilian Cerrado and popularly known as “cipó-de-são-joão”. In Brazilian folk medicine, the flowers of P. venusta are used as a general tonic and a treatment for diarrhea, vitiligo, cough, and common infections and inflammatory diseases of the respiratory system. Nevertheless, there are still no studies on its possible anti-inflammatory and analgesic effects. Methods: The P. venusta methanolic and pet. ether extract was used to evaluate the anti-inflammatory and analgesic effects in carrageenan-induced paw edema and anti analgesic activity effect in hot plate method. Results: Stem extracts of Pyrostegia venusta demonstrated the analgesic activity at dose of 50 mg/kg body weight. At the end of one-hour percent analgesia induced by petroleum ether extract is 26.34% and that by total methanolic extract is 40.69%. The total petroleum ether extract produced 43.10% inhibition of paw edema, methanolic extract showed 54.31% inhibition of paw edema. Both the extracts had comparable activity. Conclusions: Hence it revealed that Pyrostegia venusta stem extracts had potent...
