Using the chromogenic substrate, Tos-Gly-Pro-Arg-pNA-HCl (Chromozym TH, Boehringer Mannheim) plasma thrombin was estimated in six cases of envenomation by Australian elapid snakes. All patients manifested findings characteristic of defibrination due to envenomation by these snakes. Fibrin-fibrinogen degradation products were grossly elevated, as was plasma thrombin in all cases. Following treatment with antivenene, all abnormal coagulation parameters returned rapidly towards normal by 24 hours and plasma thrombin disappeared.

Intravenous infusion of endotoxin (0.25 mg/kg/hr for 4 hr) was shown to induce disseminated intravascular coagulation (DIC) in rats, which resulted in hypofibrinogenemia, prolongation of prothrombin (PT) and partial thromboplastin time (PTT), thrombocytopenia, and elevated levels of fibrinogen/fibrin degradation products (FDP). Oral administration (100 mg/kg) of the selective PAF antagonist, SM-10661 ((+/-)-cis-3,5-dimethyl-2-(3-pyridyl)thiazolidin-4-one HCl), counteracted the changes caused by the endotoxin. Intravenous infusion of SM-10661 (6mg/kg bolus 2 min before endotoxin infusion + 6 mg/kg/hr for 4 hr infusion) also counteracted DIC. When suboptimal doses of gabexate mesilate, a synthetic protease inhibitor (3 mg/kg i.p.), and SM-10661 (2 mg/kg bolus + 2 mg/kg/hr for 4 hr infusion) were administered concomitantly, hematological parameters improved. The results suggest that PAF may play a role in the pathogenesis of DIC, and that together with the results already reported for other PAF antagonists, SM-10661 may be useful in the treatment of DIC.

Gastric parietal cells in primary culture have been tested to determine their utility as a model for the study of the role of intracellular calcium ([Ca2+]i) in the control of HCl secretion. Changes in [Ca2+]i were measured in single cells on a microscope stage using the cell-permeant form of the fluorescent calcium probe, fura-2. Simultaneous images of cell fluorescence and morphology were acquired using a digitized video image analysis system and two video cameras, one for low-light level fluorescence detection and one for high resolution DIC/transmitted light images. Both histamine and carbachol, which are known stimulants of HCl secretion, increased [Ca2+]i and stimulated dramatic changes in morphology in these cultured cells. Changes in morphology were accompanied by an increased uptake of the weak base, [14C]-aminopyrine (AP), and a shift from green to red fluorescence of another weak base, acridine orange. These results indicate that cultured parietal cells, maintained under controlled conditions on a microscope stage, retain viability and secretagogue responsiveness. Thus, this cellular model appears to be suitable for correlation of changes in [Ca2+]i and activation of HCl secretion.
