RESUMEN

Thrombolytic therapy for acute myocardial infarction has been proved to be most effective if given very early in the course of evolving infarction. This study was undertaken to optimise such treatment by overcoming the in-hospital delay in the existing set-up of an industrial hospital. A quality improvement project was undertaken to analyse the existing system of thrombolysing 46 consecutive patients of acute myocardial infarction treated in six months. By following the breakthrough sequence and proceeding in steps, the causes for delay in door to needle time were identified and rectified over two months. Impact of such measures in 32 patients of acute myocardial infarction thrombolysed consecutively in the next five months was studied. Door to needle time in the baseline group (n = 46) was in the range of 15-145 minutes and the average was 48.9 minutes. Only 32.6 percent of the patients in this group were thrombolysed within 30 minutes of arrival in the hospital. After the corrective measures were implemented in a study group of 32 patients, 27 with clear indication on admission were thrombolysed on the fast track i.e. with minimum delay. Five patients with doubtful need were put on the slow track and subsequently thrombolysed. Patients with no indication or a contra-indication for thrombolysis were excluded from this study. In the fast group, door to needle time reduced to an average of 22.56 minutes with a range of 7 to 67 minutes and 75 percent of the thrombolysed patients received the infusion within 30 minutes of arrival in the hospital. Differences in door to needle time between the two groups were statistically significant. Streamlining the hospital systems and procedures can help reduce the door to needle time in thrombolysing patients of acute myocardial infarction. This could be achieved within the existing resources by applying the principles of total quality improvement.

RESUMEN

Interaction of plant and/or invertebrate lectins with mammalian cells and different microorganisms is well known. In the present study, we have demonstrated that scyllin, a low molecular weight (MW 4000) lectin from the edible crab Scylla serrata hemolymph, purified by GalNAc-Sepharon affinity column followed by Mono-Q ion exchanger in FPLC exhibits antimicrobial activity against Bacillus cereus and Escherichia coli by inhibiting endogenous respiration as well as exogenous glucose oxidation. In both the cases oxygen consumption has been measured in an oxygraph. Scyllin has produced 50% inhibition of endogenous respiration at a concentration of 110 micrograms/ml and 125 micrograms/ml in B. cereus and E. coli respectively. It also reduced the exogenous glucose oxidation by 50% at a concentration of 12 micrograms/ml and 80 micrograms/ml respectively in B. cereus and E. coli. From the above study the mechanism of bacterial growth inhibitory property of scyllin is suggested though the other studies such as inhibition of nucleic acid biosynthesis, cell wall biosynthesis etc. to evaluate its total mode of inhibitory action are not yet obtained.
