Randia spinosa (Rubiaceae family), commonly known as ‘Mainphal’ is a large shrub or small tree. The plant grows in Brazil, Ceylon, China, East tropical Africa, India, Malaya and Sumatra. The leaves of Randia spinosa is used in traditional medicine to treat diarrhea and dysentery, snake bite, wound healing, inflammation, tumors, piles, gastrointestinal and skin diseases. The objective of this study is to investigate pharmacognostical, phytochemical features and antioxidant activity of ethanol and aqueous extracts of Randia spinosa leaves by using DPPH assay method. Pharmacognostical characteristics like microscopy, total ash, acid insoluble ash, water insoluble ash and sulphated ash and loss on drying of Randia spinosa leaves were determined. The preliminary phytochemical studies were performed with various reagents and chemicals on leaf extracts in order to determine the various secondary metabolites. The ethanol and aqueous extracts of Randia spinosa leaves were screened for in-vitro antioxidant activity by oxygen radical scavenging such as 1, 1-diphenyl-2- picryl hydrazyl (DPPH) method. Pharmacognostical studies reveal the microscopical and macroscopical characters of Randia spinosa leaves....

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...
