On the supposition that excessive fibrinolysis at the rectal mucosal level may contribute to the pathogenesis of ulcerative colitis, 11 patients with this condition, in whom rectal bleeding was the predominant feature, were given a course of epsilon-aminocaproic acid therapy. Six patients responded dramatically to this treatment, there was a partial(More)
BACKGROUND In Western societies there is a winter peak in mortality, largely accounted for by respiratory and cardiovascular deaths. In view of the known seasonal variation in vitamin D, and of the postulated link between tuberculosis and vitamin D deficiency, a study was undertaken to examine whether the presentation of tuberculosis had the same seasonal(More)
Forty out of 76 patients (53%) who had suffered a cerebrovascular accident developed deep venous thrombosis of the paralysed leg, as detected with the 125I-fibrinogen technique. A further five also had thrombosis in the non-paralysed leg. A study of many predisposing risk factors provided no help either in elucidating the cause of venous thromboembolism or(More)
The haemostatic mechanism in the uterus during parturition was investigated in 12 patients being delivered by caesarean section. Detailed sequential study of the blood coagulation and fibrinolytic systems in the uterine circulation showed that placental separation is accompanied by a striking local activation of the clotting mechanism. Uterine vein blood(More)
The effect of vitamin supplements on bone metabolism indices in patients with osteoporosis has received scant attention in the literature. Over a 2-week period, vitamin supplements of K and K+D were given to 20 post-menopausal osteoporotic women with previous Colles fractures. Osteoporosis was confirmed by bone mass measurements that demonstrated that(More)
STUDY OBJECTIVE Seasonality of coronary heart disease (CHD) was examined to determine whether fatal and non-fatal disease have the same annual rhythm. DESIGN Time series analysis was carried out on retrospective data over a 10 year period and analysed by age groups ( < 45 to > 75 years) and gender. SETTING Data by month were obtained for the years(More)
The action of the venom of the gaboon viper (Bitis gabonica) on blood coagulation, platelets, and the fibrinolytic enzyme system was studied. The results confirm that the venom of Bitis gabonica has a marked anticoagulant action in vitro. The venom appears to impair clot formation by a direct proteolytic action on fibrinogen, releasing soluble breakdown(More)
