Effectiveness Of 2% And 4% Papain Gels In The Healing Of Venous Ulcers

OBJECTIVE To analyze the effectiveness of 2% and 4% papain gels in tissue repair of venous ulcers. METHOD Quasi-experimental study with consecutive sample of 16 patients with 30 venous ulcers treated at the outpatient clinic of a teaching hospital, from April to November in 2011, using a form for clinical assessment of the patient and its lesion. Variables were analyzed by Wilcoxon and McNemar test (p < 0.05). RESULTS Most participants were female; aged between 51 and 59 years; obese; with hypertension. Regarding ulcers, there was an average decrease of 7.9 cm2 (50% of its original size) in 90 days; 20% of the ulcers completely healed within 56.67 days. There was an increase in epithelialization, significant reduction in the slough and edema, improved depth, in the type and amount of exudate (p < 0.0001). CONCLUSION 2% and 4% papain gels were effective in healing venous ulcers.

The Pseudomonas aeruginosa toxin L-2-amino-4-methoxy-trans-3-butenoic acid inhibits growth and induces encystment in Acanthamoeba castellanii.

L-2-Amino-4-methoxy-trans-3-butenoic acid (AMB) is a toxic antimetabolite produced by the opportunistic pathogen Pseudomonas aeruginosa. To evaluate its importance as a potential virulence factor, we tested the host response towards AMB using an Acanthamoeba castellanii cell model. We found that AMB (at concentrations ≥ 0.5 mM) caused amoebal encystment in salt buffer, while inhibiting amoebal growth in rich medium in a dose-dependent manner. However, no difference in amoebal plaque formation was observed on bacterial lawns of wild type and AMB-negative P. aeruginosa strains. We thereby conclude that AMB may eventually act as a virulence factor, but only at relatively high concentrations.

Customer Focus Newsleter, May-June 2005, Vol. 2, no. 4

A bi-monthly bulletin to keep the department/agency management teams of state government better informed. We hope to consolidate most of the service update messages we send throughout the month and keep you updated about the work of the Customer Councils. If yours is one of the many departments who participated in the second annual DAS customer satisfaction survey recently, we thank you for taking the time to give us this important feedback. We look forward to sharing survey results with you, and pledge to consider responses carefully as we work to determine benchmarks and set future priorities.

Identification of the biosynthetic gene cluster for the Pseudomonas aeruginosa antimetabolite L-2-amino-4-methoxy-trans-3-butenoic acid.

L-2-amino-4-methoxy-trans-3-butenoic acid (AMB) is a potent antibiotic and toxin produced by Pseudomonas aeruginosa. Using a novel biochemical assay combined with site-directed mutagenesis in strain PAO1, we have identified a five-gene cluster specifying AMB biosynthesis, probably involving a thiotemplate mechanism. Overexpression of this cluster in strain PA7, a natural AMB-negative isolate, led to AMB overproduction.
