In a search for a relation between the variations of prothrombin time and chlorophacinone plasma levels, these were assessed by HPLC.

RESULTS AND CONCLUSION: In this manuscript we report the prothrombin times measured in the F7 generation after exposure to chlorophacinone, bromadiolone, difenacoum and difethialone.

The products implicated were chlorophacinone, bromadiolone, and warfarin.
The prothrombin time varied with the administered dose of Vitamin K and/or coagulation factors.

Pellets containing the anticoagulant chlorophacinone (Rozol, RO) were in the crop; the gizzard contents consisted of a pink mass of paraffin that was selectively accumulated from the paraffinized pellets.
The plasma prothrombin time of 28 sec was near that determined for control quail.

OBJECTIVE: To assess the rate and extent of ruminal degradation of warfarin, chlorophacinone, and bromadiolone in vitro and determine the oral availability and clinical and hemostatic effects of each anticoagulant rodenticide in adult sheep.
At intervals during a 240- to 360- hour period after treatment, prothrombin time (PT) was measured, plasma anticoagulant concentration was assessed, and clinical signs of rodenticide poisoning were monitored.

This study describes a generic biological screening assay designed to detect anticoagulant rodenticides based on their inhibitory action on the vitamin K epoxide reductase protein complex, resulting in an accumulation of under-carboxylated prothrombin or proteins induced by vitamin K antagonism (PIVKA-II).

The original inpatient team had not identified the specific poison (chlorophacinone).
He had grossly deranged clotting studies (prothrombin time (PT) > 200 s, activated partial thromboplastin time (APTT) 56 s) that were rapidly corrected with fresh frozen plasma and vitamin K.

This group includes the second generation 4-hydroxycoumarins brodifacoum, bromadiolone, difenacoum, flocoumafen and the indanedione derivatives chlorophacinone and diphacinone.
