Staphylococcus aureus (S. aureus) is one of the most serious gram-positive bacteria causing several infections. Because of its intrinsic ability to develop resistance to many antibiotics, nowadays only few drugs can be confidently mentioned for the treatment of S. aureus infections. The study aimed to investigate the antibiotics susceptibility pattern of S. aureus among patients. A cross-sectional study was conducted antibiotic susceptibility pattern of S. aureus among patients. A total of 323 wound and nasal swab specimens were collected and inoculated on mannitol salt agar (Oxoid) and incubated at 37oC for 18 to 24 hours. For primary cultures with bacterial growth, Gram-staining and specific biochemical tests (catalase and coagulase) were used to identify the study organism. Sensitivity of the isolates to ten commonly used antibiotics was determined by modified Kirby-Bauer antibiotic sensitivity testing method. The isolates were found to be highly resistant to penicillin G and cephalothin (98.8%; each). Chloramphenicol, amoxicillin/clavulanic acid and oxacillin were also resisted by 53.1%, 50.6% and 38.3% of the isolates, respectively. Least resistance was...

Hyperalgesia is one of the debilitating complications of diabetes. The thermal allodynia and hyperalgesia in diabetic mice may be due to the hyperactivity of C-fiber in the spinal cord. Transient receptor potential vanilloid type 1 (TRPV1) present in spinal cord and activation of C-fibre may involve in hyperalgesia in diabetic mice. Desipramine is one of the tricyclic antidepressants, effective in diabetic neuropathy. The intravenous administration of desipramine depresses the C-fibre reflex that will involve in activation of convergent neurons of the spinal cord. Thus, the present study was carried out to find out the role of TRPV1 in desipramine induced analgesic effect in diabetic hyperalgesia. Mice were administered capsaicin (1 mg kg-1), capsazepine (15 mg kg-1), desipramine (10 mg kg-1) from day 4 to day 11 after induction of diabetes and the nociceptive threshold was measured in terms of reaction time, tail flick latency and tail withdrawal latency. The nociceptive threshold was significantly (p < 0.05) lower in diabetic mice as compared with control group. Capsaicin produced a significant...

A simple, fast and precise reverse phase high performance liquid chromatographic method has been developed for the simultaneous determination of Fexofenadine hydrochloride (FEXO) and Montelukast Sodium (MONT). Efficient chromatographic separation was achieved on phenomenex C18 column (150mm x 4.6 mm, 5 μm) as stationary phase with a mobile phase comprising of 0.5% Orthophosphoric acid pH adjusted to 6 (tri ethyl amine): Acetonitrile(40:60 v/v) at a flow rate of 1.0mL min-1, column temperature of 25°C and UV detection at 240 nm. The retention time of and Fexofenadine hydrochloride and Montelukast Sodium were 2.7 min, and 4 min respectively .The linearity were found to be in the range of 72-120 μg/ml and 6-10 μg/ml Fexofenadine Hydrochloride and Montelukast Sodium respectively with correlation co efficient of 0.999. The proposed method was validated for linearity, accuracy, precision, sensitivity. All validation parameters were within the acceptable range. The developed method was successfully applied to estimate the amount of Fexofenadine hydrochloride and Montelukast Sodium in combined dosage...

In the present study, three algal species (Spirulina platensis, Chlorella pyrenoidosa and Nostoc muscorum (ATCC 2789) were used to investigate their antimicrobial and antioxidant properties against some human pathogenic bacteria and fungi (Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Micrococcus luteus and fungus Aspergillus luchuensis, Aspergillus niger, Fusarium oxysporum). Four different solvents namely methanol, acetone, n-hexane and water were used for extraction. The present investigation showed that methanolic extract was more effective against the pathogenic bacteria and fungi. Methanolic extract of C. pyrenoidosa and N. muscorum was found to be most effective against P. aeruginosa while methanolic extract of S. platensis showed maximum activity against S. aureus. S. platensis showed maximum antifungal activity in comparison to other algal extracts. Antioxidant activity was determined by free radical scavenging activity (Nitric oxide radical scavenging activity) and it was found that methanolic extract of S. platensis showed maximum antioxidant...

Chronic myeloid leukemia (CML) is a malignancy of hematopoietic stem cells associated with a t(9;22) translocation that forms the Philadelphia chromosome and creates a novel fusion gene, BCR-ABL. For those who are resistant or intolerant to imatinib, second-generation tirosino-kinase inhibitor, as dasatinib, has been shown to be efficacious in all phases of the disease. Once dasatinib is taken orally and the treatment has no defined end point, a complete follow up method, including a pharmacotherapy follow up, to monitor the CML patients is essential to define adherence and treatment safety. To systematically review follow up methods of CML patients treated with dasatinib in clinical trials (CT) either randomized (RCT), or not (NRCT) and prospective cohorts (PC) a sensitized research was performed on the databases Medline (Pubmed), Cochrane Library (OVID), Embase (Elsevier) and Lilacs. Four RCT, four NRCT and three PC were identified and contained data about patients follow up, which proved to be well established and structured. Adverse drug reactions grades III and IV description was in accordance with...
