reduced during the first six months by non-closure of the defect. Presumably non-closure allows cerebrospinal fluid to escape from the open neural tube, postponing the development of hydrocephalus until epithelium has formed. As deferred shunt operations are associated with a better prognosis,4 nonclosure may in fact be advantageous, delaying the onset of ventriculitis until the child is immuno...

The metabolism of 5-aminosalicylate (5AS) by a bacterial strain, Pseudomonas sp. BN9, was studied. Intact cells of Pseudomonas sp. BN9 grown with 5AS oxidized 5AS and 2,5-dihydroxybenzoate (gentisate), whereas cells grown with gentisate oxidized only the growth substrate of all substituted salicylates tested. Cell extracts from Pseudomonas sp. BN9 catalysed the stoichiometric reaction of 1 mol ...

Background. Inflammatory bowel diseases — Crohn’s disease and ulcerative colitis are chronic gastrointestinal affecting young people of working age. An alternative to basic therapy (5-aminosalicylic acid) for inflammatory is the use ozone, which has anti-inflammatory, immunomodulatory, antibacterial properties no side effects in therapeutic concentrations. Objective. To perform clinical morphol...
