SummaryThe incidence of stroke in a group of 499 treated hypertensive patients was closely related to the adequacy of control of hypertension. This trend was independent of the level of diastolic blood pressure at presentation, and differed markedly from the incidence of myocardial infarction and angina pectoris which did not vary with adequacy of control.

Summary A case of disseminated intravascular coagulation due to staphylococcal septicaemia is described in which the source of infection was likely to have been acupuncture therapy.

In a study to determine the most suitable method of expressing activity of jejunal mucosal enzymes, the effect of variation of thickness and protein concentration of biopsies was assessed. Despite wide variation of both these factors, we found no advantage in expressing enzyme activity by reference to either surface area or protein content. Expression of activity by reference to weight of biopsy gave the lowest variance for each of the enzymes studied and, since it is also the easiest measurement to make, it would appear to be the preferred means of expressing jejunal mucosal enzyme activity.
