Intravascular Hemolysis and Ultrastructural Changes of Erythrocytes in Lethal Canine Endotoxin Shock
Bibliographic record
Abstract
Intravascular hemolysis and ultrastructure of erythrocytes from liver sinusoids were studied during and after infusion of Escherichia coli endotoxin in Labrador retriever dogs. Endotoxin infusion caused hemoconcentration, and induced disseminated intravascular coagulation (DIC), characterized by a rapid drop of platelet numbers, a gradual consumption of coagulation factors and activation of fibrinolysis. Advanced DIC and circulatory shock gradually developed, and the animals died after 7-15 h. Plasma hemoglobin concentrations did not rise for several hours, but late in the experimental period a significant intravascular hemolysis was constantly found. Circulating adenosine diphosphate (ADP) did not appear. During shock, liver biopsies revealed accumulation of erythrocytes often disintegrated within distended sinusoidal lumina. In advanced shock the fragmented erythrocyte seemed to form occlusive masses within the vessels. A fibrin-like material frequently appeared adjacent to the red cells. However, it did not have the periodicity characteristic for fibrin, and the ultrastructure of the material was very similar to that inside the erythrocytes. None of these changes were induced by saline infusion in control animals. The lack of fibrin formation and the late development of intravascular hemolysis indicate that red cell breakdown was of little importance for the initiation and progress of DIC.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
