Rat inferior caval vein (ICV) ligature and particular new insights with the stable gastric pentadecapeptide BPC 157.
    Vascular pharmacology, 2018, Volume: 106

    Rat inferior caval vein (ICV) ligation (up to the right ovarian vein (ROV)) commonly represents a recapitulation of Virchow: with ligation leading to vessel injury, stasis, thrombosis and hemodynamic changes. We revealed that BPC 157's therapy collectively attenuated or counteracted all these events and the full syndrome.. We applied BPC 157 (10 μg, 10 ng/kg) as an early regimen or as a delayed therapy. Assessment includes gross assessment by microcamera; microscopy, venography, bleeding, blood pressure, ECG, thermography, MDA and NO-level in plasma and ICV, and gene expression.. Direct vein injury, thrombosis, thrombocytopenia, prolonged bleeding were all counteracted. Also, rapid presentation of collaterals and redistribution of otherwise trapped blood volume (bypassing through the left ovarian vein (LOV) and other veins), with venous hypertension, arterial hypotension and tachycardia counteraction were shown. BPC 157-rats presented raised plasma NO-values, but normal MDA-values; in ICV tissue reverted low NO-values and counteracted increased MDA-levels. Altered expression of EGR, NOS, SRF, VEGFR and KRAS in ICV, ROV and LOV revealed increased or decreased levels, while some genes continuously remained unchanged.. As a new insight, BPC 157 application largely attenuated or even completely eliminated all consequences of ICV ligation in rats.

Pentadecapeptide BPC 157 Reduces Bleeding and Thrombocytopenia after Amputation in Rats Treated with Heparin, Warfarin, L-NAME and L-Arginine.
    PloS one, 2015, Volume: 10, Issue:4

    BPC 157 is a stable gastric pentadecapeptide recently implicated with a role in hemostasis. While NO is largely implicated in hemostatic mechanisms, in tail-amputation-models under heparin- and warfarin-administration, both the NO-synthase (NOS)-blocker, L-NAME (prothrombotic) and the NOS-substrate L-arginine (antithrombotic), were little investigated. Objective. To investigate the effect of L-NAME and L-arginine on hemostatic parameters, and to reveal the effects of BPC 157 on the L-NAME- and L-arginine-induced hemostatic actions under different pathological condition: tail amputation without or with anticoagulants, heparin or warfarin.. Tail amputation, and/or i.v.-heparin (10 mg/kg), i.g.-warfarin (1.5 mg/kg/day for 3 days) were used in rats. Treatment includes BPC 157, L-NAME, L-arginine, per se and their combination.. After (tail) amputation, with or without i.v.-heparin or i.g.-warfarin, BPC 157 (10 μg/kg, 10 ng/kg, i.p., i.v. (heparin), 10 μg/kg i.g. (warfarin)) always reduced bleeding time and/or haemorrhage and counteracted thrombocytopenia. As for L-NAME and/or L-arginine, we noted: L-arginine (100 mg/kg i.p.)-rats: more bleeding, less/no thrombocytopenia; L-NAME (5 mg/kg i.p.)-rats: less bleeding (amputation only), but present thrombocytopenia; L-NAME+L-arginine-rats also exhibited thrombocytopenia: L-NAME counteracted L-arginine-increased bleeding, L-arginine did not counteract L-NAME-thrombocytopenia. All animals receiving BPC 157 in addition (BPC 157 μg+L-NAME; BPC 157 μg+L-arginine, BPC 157 μg+L-NAME+L-arginine), exhibited decreased haemorrhage and markedly counteracted thrombocytopenia.. L-NAME (thrombocytopenia), L-arginine (increased haemorrhage) counteraction and BPC 157 (decreased haemorrhage, counteracted thrombocytopenia) with rescue against two different anticoagulants, implicate a BPC 157 modulatory and balancing role with rescued NO-hemostatic mechanisms.

Pentadecapeptide BPC 157 reduces bleeding time and thrombocytopenia after amputation in rats treated with heparin, warfarin or aspirin.
    Thrombosis research, 2012, Volume: 129, Issue:5

    Recently, in rat abdominal aorta terminoterminal-anastomosis the stable gastric pentadecapeptide BPC 157 prevents obstructive thrombus formation and rapidly destroys already formed obstructive thrombus. Also, BPC 157 wound healing may signify the clot as conductive matrix or "scaffold" to speed up wound healing process, and decrease bleeding. Here, in rats, BPC 157 (10 μg/kg, 10 ng/kg) improved always reduced bleeding time and amount of bleeding after (tail) amputation only, heparin (250 mg/kg, 25mg/kg, 10mg/kg i.v.), warfarin (1.5mg/kg i.g. once daily for 3 consecutive days), aspirin (0.1g/kg i.g. (once daily/3 consecutive days) or 1.0 g/kg i.p. once), and amputation associated with those agents application. BPC 157 counteracting regimens (i.v., i.p., i.g. (immediately after any challenge)) correspondingly follow the route of bleeding-agents application. All heparin-, warfarin-, and aspirin-rats and normal-rats that received BPC 157 exhibited lesser fall in platelets count. BPC 157 attenuated over-increased APTT-, TT-values in 10mg/kg heparin-rats, but did not influence heparin activity (anti-Xa test). Indicatively, unless counteracted in BPC 157 rats, excessive bleeding-acute thrombocytopenia (<20% of initial values in heparin-rats) approaches substantial fall in platelets count known in type II HIT. Also, BPC 157 markedly prolongs the survival time (heparin-rats, 25mg/kg, right foot amputation).
