[Thrombocyte aggregation after abdominal hysterectomy with combined prevention of thromboembolism using 6% macrodex and sintrom].

Thrombocyte aggregation was investigated, according to Born, in 14 patients who underwent abdominal hysterectomy due to benign illness. The patients received dextran 60 and 4-hydroxycoumarin as prophylactic therapy for early and late thromboembolism. The following results were obtained: 1. The ability of the thrombocytes to aggregate was reduced by half, 2 hours postoperatively, after administration of dextran 60, and remained at this level during the first postoperative day. This action was independent of the concentration and type of agent used in the aggregation test. The original values were attained again on the 4th postoperative day. The speed and force of desaggregation showed reverse behaviour. 2. Results bore no relationships to the age of the patient. 3. This combined prophylactic therapy with macrodex (500 ml intraoperatively) and sintrom (from the 1st postoperative day) seems to give adequate protection in both the intra- and postoperative risk phases.

Differences in pyrogen production by mononuclear phagocytes and by fibroblasts or HeLa cells.

Phagocytosis of bacteria stimulates "professional" phagocytes to produce and release endogenous pyrogen (EP), the protein that mediates fever. To determine whether "nonprofessional" phagocytes also have this capacity, mouse and human fibroblasts and HeLa cells were cultured after ingestion of latex or chicken erythrocytes (CE), and EP release into culture supernate measured by mouse assay. No detectable pyrogen was released by these cell types after phagocytosis, whereas both latex and CE stimulated EP production by cultured mouse macrophages. These studies support the hypothesis that only professional phagocytes of bone marrow origin synthesize EP and induce fever.

Traumatic rupture of the ascending aorta and aortic valve following blunt chest trauma.

Traumatic rupture of the aorta at the level of the isthmus is a well-recognized injury following blunt chest trauma. By contrast, rupture of the ascending aorta and of the aortic valve in a road traffic accident is rare and does not appear to have been previously reported. The occurrence of such an injury in a 56-year-old man involved in a road traffic accident is reported. The diagnosis was made preoperatively following aortography and successful surgical correction involved aortic valve replacement with resection and grafting of the damaged area of the ascending aorta. The probable mechanisms involved in the production of this unusual injury are discussed.

Pyrogen from mouse macrophages causes fever in mice.

Mouse peritoneal macrophages, after phagocytosis, release an endogenous (leucocyte) pyrogen. Intravenous injection of stimulated cell culture supernatant produces a prompt, monophasic fever in mice maintained in a 35 degree environment. The pyrogen is distinct from endotoxin, and resembles cell pyrogens of other species in heat-lability and pronase sensitivity. Human leucocyte pyrogen produces identical responses in mice. Measurement of fever in mice appears to provide a sensitive biological assay for endogenous pyrogens.
