Bacteriocin production by Clostridium acetobutylicum in an industrial fermentation process.

High titers of a noninducible bacteriocin were produced by Clostridium acetobutylicum in a molasses fermentation medium used for the industrial production of solvents. Release of the bacteriocin towards the end of the exponential growth phase was accompanied by lysis of the culture and inhibition of the production of solvents. The producer cells were sensitive to the bacteriocin, which only affected other C. acetobutylicum strains and a Clostridium felsineum strain. The thermolabile bacteriocin was not inactivated by protease enzymes and had no optimum stability between pH 4 and 5. The sedimentation coefficient of the bacteriocin was 6S.

Blunt abdominal trauma.

Blunt abdominal trauma is a possible sequel of many accidents and can result in death from hemorrhage or sepsis if it is not detected early and managed aggressively. A thorough history of the causative accident, a systematic abdominal examination, selected laboratory studies, and x-ray films are helpful in establishing the diagnosis. Peritoneal lavage is, however, the most reliable assessment tool (besides an exploratory laparotomy) for confirming significant viscus injury and intra-abdominal hemorrhage. Nurses who are assisting in the evaluation of trauma victims should be thoroughly familiar with the mechanics responsible for blunt abdominal injury, the initial steps for stabilizing the victim, and the usual tests and procedures that aid in diagnosis.

Simple lignocaine regimen for transit to hospital after myocardial infarction.

A simple combined intravenous/intramuscular regimen is described for lignocaine administration in the early vulnerable stage of myocardial infarction. Plasma levels in the therapeutic range are attained. This allows adequate drug protection during transport to hospital when an intravenous regimen may be impractical or impossible.

Practolol in acute myocardial infarction.

A double blind trial of practolol in coronary heart disease has been conducted for 2 years. In 298 patients with acute myocardial infarction there was no reduction in overall mortality. In a group with initial heart rate over 100 per minute mortality was significantly lowered up to 1 year. Of 484 patients with coronary heart disease treatment for 2 years did not produce a significant reduction in infarction or sudden death. Beta-adrenergic blocking drugs have been shown to reduce left ventricular work and to have an antiarrhythmic action. On these grounds they would seem theoretically to have a place in the management of acute myocardial infarction. Practolol is a cardio-selective beta-blocking agent with an intrinsic sympathomimetic action, but devoid of local anaesthetic effect. It has been found effective in post infarction arrhythmias (1). In early infarction it reduces the area of necrosis as measured by surface ST segment mapping (2).
