AB  - Findings from epidemiological studies indicate that polyphenols, widespread in
human diet and with numerous biological activities, act cardioprotectively. Procyanidins are
subclass of polyphenols with high content in commonly consumed foods and beverages, such
as grapes, tea, chocolate, nuts and apples. Cardioprotective abilities of procyanidins, might, at
least partly, attribute to their vasodilator properties. Since exact mechanisms of procyanidin
B2-induced vasorelaxation are unknown, our study aimed to investigate relaxant effect of
procyanidin B2 on isolated human saphenous vein (HSV) and its underlying mechanisms.
Discarded segments of HSV were collected from patients undergoing bypass surgery and
studied in organ baths. Procyanidin B2 caused concentration-dependent relaxation of HSV
precontracted by phenylephrine. The relaxation was strongly affected by inhibitors of
NO/cGMP pathway, L-NAME, hydroxocobalamin and ODQ. Indomethacin, a cyclooxygenase
inhibitor, significantly reduced only relaxation produced by the highest concentrations of
procyanidin B2. Combination of apamin and TRAM-34, selective blockers of small- and
intermediate-conductance Ca 2+ -activated K+ (KCa ) channels (SKCa and IK Ca ), in the presence of
L-NAME and indomethacin, did not additionally affect procyanidin B2-induced relaxation.
Additionally, relaxation induced by procyanidin B2 was partially attenuated by 4-
aminopyridine, predominant blocker of voltage-gated K+ (KV) channels, significantly
inhibited by glibenclamide, selective ATP-sensitive K+ (KATP) channels inhibitor, and almost
abolished by iberiotoxin, highly selective blocker of large-conductance KCa (BKCa ). Our results
revealed that procyanidin B2 acts as a potent vasodilator on isolated human venous graft.
Mechanism of this relaxation of HSV probably involves stimulation of NO production, as well
K+ channels opening, especially BK Ca , and partially KATP and KV

Indometacin, inhibitor ciklooksigenaze, značajno je umanjio samo relaksaciju izazivanu

AB  - Hydrogen sulfide (H2S) represents the third and the youngest member of the gaseous transmitters family. The dominant effect of H2S on isolated vessels is vasodilation. As the mechanism of H2S-induced relaxation in human vessels remains unclear, the present study aimed to investigate the effects of H2S donor, sodium hydrosulfide (NaHS), on isolated human saphenous vein (HSV) and to determine the mechanism of action. Our results showed that NaHS (1 µM–3 mM) induced a concentration-dependent relaxation of endothelium-intact HSV rings pre-contracted by phenylephrine. Pre-treatment with L-NAME, ODQ and KT5823 significantly inhibited NaHS-induced relaxation, while indomethacin induced partial inhibition. Among K+ channel blockers, the combination of apamin and TRAM-34 significantly affected the relaxation produced by NaHS, while iberiotoxin and glibenclamide only reduced maximal relaxation of HSV. NaHS partially relaxed endothelium-intact rings pre-contracted by high K+, as well as phenylephrine-contracted rings in the presence of nifedipine. Additionally, the incubation of HSV rings with NaHS increased NO production. These results demonstrate that NaHS produces the concentration- and endothelium-dependent relaxation of isolated HSV. Vasorelaxation to NaHS probably involves activation of NO/cGMP/PKG pathway and partially prostacyclin. In addition, different K+ channels subtypes, especially SKCa and IKCa, as well as BKCa and KATP channels in high concentrations of NaHS, probably participate in the NaHS-induced vasorelaxation.

AB  - In this study, we aimed to investigate relaxant effect of flavanol (-)-epicatechin on the isolated human saphenous vein (HSV), as a part of its cardioprotective action, and to define the mechanisms underlying this vasorelaxation. (-)-Epicatechin induced a concentration-dependent relaxation of HSV pre-contracted by phenylephrine. Among K+ channel blockers, 4-aminopyridine, margatoxin, and iberiotoxin significantly inhibited relaxation of HSV, while glibenclamide considerably reduced effects of the high concentrations of (-)-epicatechin. Additionally, (-)-epicatechin relaxed contraction induced by 80 mM K+, whereas in the presence of nifedipine produced partial relaxation of HSV rings pre-contracted by phenylephrine. In Ca2+-free solution, (-)-epicatechin relaxed contraction induced by phenylephrine, but had no effect on contraction induced by caffeine. A sarcoplasmic reticulum Ca2+-ATPase inhibitor, thapsigargin, significantly reduced relaxation of HSV produced by (-)-epicatechin. These results demonstrate that (-)-epicatechin produces endothelium-independent relaxation of isolated HSV rings. Vasorelaxation to (-)-epicatechin probably involves activation of 4-aminopyridine- and margatoxin-sensitive K-V channels, BKCa channels, and at least partly, K-ATP channels. In addition, not only the inhibition of extracellular Ca2+ influx, but regulation of the intracellular Ca2+ release, via inositol-trisphosphate receptors and reuptake into sarcoplasmic reticulum, via stimulation of Ca2+-ATPase, as well, most likely participate in (-)-epicatechin-induced relaxation of HSV.

AB  - Dyslipidemia is the leading risk factor for the development of atherosclerosis and associated consequences, such as coronary heart disease, ischemic cerebrovascular and peripheral vascular disease. These diseases are the major cause of mortality in the world and in Europe as well, where they are responsible for around 45% of all deaths. Treatment of dyslipidemia includes the use of statins, ezetimibe, fibrates, niacin, bile acids sequestrants and omega-3 fatty acids. Although statins play the major role in dyslipidemia treatment by reducing the risk of cardiovascular (CV) events by 30%, there is a need for additional new drugs that reduce the residual risk even more. PCSK9 inhibitors, apolipoprotein B (apoB) synthesis inhibitors, MTP inhibitors and CETP inhibitors are already approved for the specific indications, or are in the advanced stages of clinical investigation. Two PCSK9 inhibitors, alirocumab and evolocumab are approved for use in combination with statins for the treatment of heterozygous familial hypercholesterolemia (FH), but also in patients with clinical atherosclerotic CV diseases who require additional low-density lipoprotein cholesterol (LDL-C) level reduction. In addition, evolocumab is approved for use in patients with homozygous FH. Mipomersen, apoB synthesis inhibitor, lomitapide, and oral MTP inhibitor are currently approved in the treatment of patients with homozygous FH as an adjunct to the maximum tolerated doses of statins and other lipid-lowering drugs. Although the new lipid-lowering agents produce significant LDL-C level reduction, more clinical studies are necessary to confirm their efficacy and safety in dyslipidemia treatment.
AB  - Dislipidemije su vodeći faktor rizika za razvoj ateroskleroze i njenih posledica, kao što su koronarna bolest srca, ishemična cerebrovaskularna i periferna vaskularna bolest. Ove bolesti su glavni uzrok mortaliteta, kako u svetu tako i u Evropi, gde su odgovorne za 45% ukupne smrtnosti. Terapija dislipidemija uključuje primenu: statina, ezetimiba, fibrata, niacina, smola koje vezuju žučne kiseline i omega-3 masnih kiselina. Od pomenutih lekova, vodeću ulogu u terapiji dislipidemija imaju statini. Treba istaći da uprkos primeni statina, koji redukuju rizik od pojave kardiovaskularnih (KV) događaja za oko 30%, još uvek ostaje tzv. rezidualni rizik za nastanak KV događaja, što ukazuje da su potrebni novi lekovi koji će dalje redukovati rezidualni rizik. Novi lekovi u terapiji dislipidemija uključuju PCSK9 inhibitore, inhibitore sinteze apolipoproteina B (apoB), MTP inhibitore i CETP inhibitore, koji su ili već odobreni za primenu u određenim indikacijama, ili se nalaze u odmaklim fazama kliničkog ispitivanja. Alirokumab i evolokumab, dva PCSK9 inhibitora, odobrena su za primenu, u kombinaciji sa statinima, u terapiji heterozigotne familijarne hiperholesterolemije (FH), kao i kod bolesnika sa kliničkim aterosklerotičnim KV bolestima koji zahtevaju dodatnu redukciju nivoa lipoproteina male gustine (low-density lipoprotein cholesterol, LDL-C). Pored toga, evolokumab je odobren za primenu kod bolesnika sa homozigotnom FH. Mipomersen, inhibitor sinteze apoB, i lomitapid, oralni MTP inhibitor, su, odobreni za primenu samo kod bolesnika sa homozigotnom FH kao dodatak maksimalnoj tolerišućoj dozi statina i drugih hipolipemika. Iako novi hipolipemici značajno redukuju nivo LDL-C, neophodno je sprovesti studije, duže i sa većim brojem ispitanika, koje će potvrditi njihovu efikasnost i bezbednost i time omogućiti njihovu širu primenu u terapiji dislipidemija.

AB  - Background: The superiority of dabigatran has been well proven in the standard dosing regimen in prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation (NVAF) and extended venous thromboembolism (VTE) treatment. Dabigatran, an anticoagulant with a good safety profile, reduces intracranial bleeding in patients with atrial fibrillation and decreases major and clinically relevant non-major bleeding in acute VTE treatment. However, several important clinical issues are not fully covered by currently available directions with regard to dabigatran administration. The prominent one is reflected in the fact that dynamic impairment in renal function due to dehydratation may lead to haemorragic complications on the one hand, while on the other hand glomerular hyperfiltration may be a possible cause of dabigatran subdosing, hence reducing the drug's efficacy. Furthermore, limitations of the Cockcroft-Gault formula, considered a standard equation for assessing the renal function, may imply that other calculations are likely to obtain more accurate estimates of the kidney function in specific patient populations. Method and Conclusions: Although not routinely recommended, a possibility of monitoring dabigatran in special clinical settings adds to optimization of its dosage regimens, timely perioperative care and administration of urgently demanded thrombolytic therapy, therefore significantly improving this drug's safety profile. Despite the fact that dabigatran has fewer reported interactions with drugs, food constituents, and dietary supplements, certain interactions still remain, requiring considerable caution, notably in elderly, high bleeding risk patients, patients with decreased renal function and those on complex drug regimens. Additionally, upon approval of idarucizumab, an antidote to dabigatran solution, hitherto being a major safety concern, has been finally reached, which plays a vital role in life-threatening bleeding and emergency interventions and surgery.

AB  - The aim of the present study was to investigate and characterize vasorelaxant effect of procyanidin B2 on human internal mammary artery (HIMA) as one of the mechanisms of its protective effect against vascular risk. Procyanidin B2 induced strong concentration-dependent relaxation of HIMA rings pre-contracted by phenylephrine. Pretreatment with L-NAME, a NO synthase inhibitor, hydroxocobalamin, a NO scavenger, and ODQ, an inhibitor of soluble guanylate cyclase, significantly inhibited procyanidin B2-induced relaxation of HIMA, while indomethacin, a cyclooxygenase inhibitor, considerably reduced effects of low concentrations. Among K+ channel blockers, iberiotoxin, a selective blocker of large conductance Ca2+-activated K+ channels (BKCa), abolished procyanidin B2-induced relaxation, glibenclamide, a selective ATP-sensitive K+(K-ATP) channels blocker, induced partial inhibition, while 4-aminopyridine, a blocker of voltage-gated K+(K-V) channels, and TRAM-34, an inhibitor of intermediate-conductance Ca2+-activated K+(IKCa) channels, slightly reduced maximal relaxation of HIMA. Further, procyanidin B2 relaxed contraction induced by phenylephrine in Ca2+-free Krebs solution, but had no effect on contraction induced by caffeine. Finally, thapsigargin, a sarcoplasmic reticulum Ca2+-ATPase inhibitor, significantly reduced relaxation of HIMA produced by procyanidin B2. These results demonstrate that procyanidin B2 produces endothelium-dependent relaxation of HIMA pre-contracted by phenylephrine. This effect is primarily the result of an increased NO synthesis and secretion by endothelial cells and partially of prostacyclin, although it involves activation of BKCa and K-ATP, as well as K-V and IKCa channels in high concentrations of procyanidin B2.

AB  - Resveratrol is a phytoalexin produced in a number of plant species including grapes. The benefit of resveratrol to health is widely reported. Resveratrol has been found to promote relaxation of non-pregnant and pregnant uterus, but its mechanism of action is unclear. The aims of our study were to investigate the involvement of inwardly rectifying potassium channels (Kir) in inhibitory effects of resveratrol on three models of contractions of non-pregnant rat uterus: the spontaneous rhythmic contractions (SRC), oxytocin-elicited phasic contractions and tonic oxytocin-elicited contractions. Uterine strips were obtained from virgin female Wistar rats in oestrus. Strips were mounted into organ bath for recording isometric tension in Krebs-Ringer solution. Experiments followed a multiple curve design. In order to test the involvement of Kirchannels in a mechanism of action of resveratrol (1-100 μM),BaCl2 (1 mM),a antagonist of inwardly rectifying potassium channels was used. Resveratrol induced a concentration-dependent relaxation of all models of contractions. BaCl2 antagonized the response to resveratrolon SRC and oxytocin-elicited phasic contractions. Relaxation achieved by resveratrolon tonic oxytocin-elicited concentrations was insensitive to BaCl2.The antagonism of resveratrol effects by inwardly rectifying potassium channels antagonist suggests that Kir channels are involved in resveratrol action on phasic contractions of rat uterus. Inhibitory effect of resveratrol on tonic contractions did not include Kir channels.

In order to test the involvement of Kirchannels in a mechanism of action of resveratrol (1-100 μM),BaCl2 (1 mM),a antagonist of inwardly rectifying potassium channels was used. Resveratrol induced a concentration-dependent relaxation of all models of contractions. BaCl2 antagonized the response to resveratrolon SRC and oxytocin-elicited phasic contractions. Relaxation achieved by resveratrolon tonic oxytocin-elicited concentrations was insensitive to BaCl2.The antagonism of resveratrol effects by inwardly rectifying potassium channels antagonist suggests that Kir channels are involved in resveratrol action on phasic contractions of rat uterus. Inhibitory effect of resveratrol on tonic contractions did not include Kir channels.",

AB  - As we previously demonstrated the role of different K+ channels in the action of nicorandil on human saphenous vein (HSV) and human internal mammary artery (HIMA), this study aimed to analyse the contribution of the cGMP pathway in nicorandil-induced vasorelaxation and to determine the involvement of cGMP in the K+ channel-activating effect of nicorandil. An inhibitor of soluble guanylate cyclase (GC), ODQ, significantly inhibited nicorandil-induced relaxation, while ODQ plus glibenclamide, a selective ATP-sensitive K+ (KATP) channel inhibitor, produced a further inhibition of both vessels. In HSV, ODQ in combination with 4-aminopyridine, a blocker of voltage-gated K+ (K-V) channels, did not modify the concentration-response to nicorandil compared with ODQ, whereas in HIMA, ODQ plus iberiotoxin, a selective blocker of large-conductance Ca2+-activated K+ (BKCa) channels, produced greater inhibition than ODQ alone. We showed that the cGMP pathway plays a significant role in the vasorelaxant effect of nicorandil on HSV and HIMA. It seems that nicorandil directly opens KATP channels in both vessels and BKCa channels in HIMA, although it is possible that stimulation of GC contributes to KATP channels activation in HIMA. Contrary, the activation of K-V channels in HSV is probably due to GC activation and increased levels of cGMP.

AB  - Evidences have suggested that flavanol compound (-)-epicatechin is associated with reduced risk of cardiovascular diseases. One of the mechanisms of its cardioprotective effect is vasodilation. However, the exact mechanisms by which (-)-epicatechin causes vasodilation are not yet clearly defined. The aims of the present study were to investigate relaxant effect of flavanol (-)-epicatechin on the isolated human internal mammary artery (HIMA) and to determine the mechanisms underlying its vasorelaxation. Our results showed that (-)-epicatechin induced a concentration-dependent relaxation of RNA rings pre-contracted by phenylephrine. Among the K+ channel blockers, 4-aminopyricline (4-AP) and margatoxin, blockers of voltage gated K+ (K-V) channels, and glibenclamide, a selective ATP sensitive K+ (K-ATP,) channels blocker, partly inhibited the (-)-epicatechin-induced relaxation of HIMA, while iberiotoxin, a most selective blocker of large conductance Ca2+-activated K+ channels (BKCa), almost completely inhibited the relaxation. In rings pre-contracted by 80 mM K+, (-)-epicatechin induced partial relaxation of HIMA, whereas in Ca2+-free medium, (-)-epicatechin completely relaxed HIMA rings pre-contracted by phenylephrine and caffeine. Finally, thapsigargin, a sarcoplasmic reticulum Ca2+-ATPase inhibitor, slightly antagonized (-)-epicatechin-induced relaxation of HIMA pre-contracted by phenylephrine. These results suggest that (-)-epicatechin induces strong endothelium independent relaxation of HIMA pre-contracted by phenylephrine whilst 4-AP- and rnargatoxin-sensitive K-V channels, as well as BKCa and K-ATP channels, located in vascular smooth muscle, mediate this relaxation. In addition, it seems that (-)-epicatechin could inhibit influx of extracellular Ca2+, interfere with intracellular Ca2+ release and re uptake by the sarcoplasmic reticulum.

AB  - The ATP-sensitive K+ channels opener (KATPCO), P1075 [N-cyano-N'-(1,1-dimethylpropyl)-N?-3-pyridylguanidine], has been shown to cause relaxation of various isolated animal and human blood vessels by opening of vascular smooth muscle ATP-sensitive K+ (KATP) channels. In addition to the well-known effect on the opening of KATP channels, it has been reported that vasorelaxation induced by some of the KATPCOs includes some other K+ channel subtypes. Given that there is still no information on other types of K+ channels possibly involved in the mechanism of relaxation induced by P1075, this study was designed to examine the effects of P1075 on the rat renal artery with endothelium and with denuded endothelium and to define the contribution of different K+ channel subtypes in the P1075 action on this blood vessel. Our results show that P1075 induced a concentration-dependent relaxation of rat renal artery rings pre-contracted by phenylephrine. Glibenclamide, a selective KATP channels inhibitor, partly antagonized the relaxation of rat renal artery induced by P1075. Tetraethylammonium (TEA), a non-selective inhibitor of Ca2+-activated K+ channels, as well as iberiotoxin, a most selective blocker of large-conductance Ca2+-activated K+ (BKCa) channels, did not abolish the effect of P1075 on rat renal artery. In contrast, a non-selective blocker of voltage-gated K+ (KV) channels, 4-aminopyridine (4-AP), as well as margatoxin, a potent inhibitor of KV1.3 channels, caused partial inhibition of the P1075-induced relaxation of rat renal artery. In addition, in this study, P1075 relaxed contractions induced by 20 similar to mM K+, but had no effect on contractions induced by 80 similar to mM K+. Our results showed that P1075 induced strong endothelium-independent relaxation of rat renal artery. It seems that KATP, 4-AP- and margatoxin-sensitive K+ channels located in vascular smooth muscle mediated the relaxation of rat renal artery induced by P1075.

AB  - Because adrenergic contractions can contribute to the development of life-threatening spasm of coronary artery bypass graft, this study was performed to investigate the effect of adenosine 3-phosphate (ATP)-sensitive K(+) channel (K(ATP)) opener P1075 on contractions of isolated human saphenous vein (HSV) and human internal mammary artery (HIMA). Phasic contractions were evoked by electric field stimulation (20 Hz) and noradrenaline. The sustained contractions were evoked by phenylephrine. The presence of pore-forming Kir6.1 and Kir6.2 subunits of the K(ATP) channels in the HIMA and only Kir6.2 in the HSV was confirmed immunomorphologically. P1075 inhibited in the HSV only, the electrical field stimulation contractions more strongly than noradrenaline contractions. In addition, the phenylephrine contractions of HSV were more sensitive to P1075 in comparison to those of HIMA. Glibenclamide, a K(ATP) channel blocker antagonized the vasodilatation produced by P1075 in both grafts differently, because its effect was more prominent on the P1075-induced inhibition of contractions of HSV than of HIMA. We conclude that P1075 has a vasorelaxant effect and inhibited adrenergic contractions of the tested grafts. This effect is graft and vasoconstrictor selective and seems to be mediated by Kir6.1-and/or Kir6.2-containing K(ATP) channels. Thus, P1075 can be considered as a potential drug in the prevention of graft spasm.

AB  - Recently it has been suggested that resveratrol relaxes different isolated arteries. The present study addressed the question whether different ion channels are involved in the endothelium-independent mechanism of vasodilatation induced by resveratrol. For that purpose, we tested the action of resveratrol on the rat mesenteric artery without endothelium. Resveratrol induced con centration-dependent relaxation of rat mesenteric artery. Among the K+-channel blockers, 4-amynopiridine (4-AP) moderately antagonized the resveratrol-induced relaxation, while glibendamide, tetraethylammonium chloride, charybdotoxin, margatoxin, and barium chloride did not inhibit resveratrol-induced vasorelaxation. In rings, precontracted with 100 mM K+, the relaxant responses to resveratrol were highly significantly shifted to the right compared to those obtained in rings precontracted with phenylephrine, but resveratrol-induced maximal relaxation was only slightly affected. In order to minimize the influence of K+ channels and voltage-gated Ca2+ channels (VGCCs) in vascular smooth muscle, the third contraction was made by 100 in M K- in the presence of nifedipine. The relaxant response to resveratrol was abolished. Thus, the mechanism of vasorelaxation induced by resveratrol probably involves activation of 4-AP-sensitive K+ channels. Its ability to completely relax the mesenteric artery precontracted with K+-rich solution suggests that K channel-independent mechanism(s) are involved in its vasorelaxant effect. It seems that interaction with VGCCs plays a part in this K+ channel-independent effect of resveratrol.

AB  - To investigate whether the antivasoconstrictor effect of P1075, a potassium channel openers, could be partly due to modulation of neurotransmitter release from adrenergic nerve endings we analysed the presynaptic and postsynaptic effects of P1075 on the isolated human saphenous vein (HSV). The HSV rings were contracted by electrical field stimulation (EFS) or by exogenous noradrenaline (10 μM; NA). The repetitive transmural EFS was carried out at 20 Hz with square wave pulses of 0.3 ms duration and supramaximal voltage. The contraction of the HSV in response to transmural EFS recorded in our experiments are neurogenic in nature, as this effect was abolished by tetrodotoxin (1 μM). We have also found that phentolamine (1 μM) inhibited almost completly (90 ″ 2%) the HSV contractions to EFS suggesting that this response was mediated by NA release from perivascular sympathetic nerve endings activating postjuncional α adrenoceptors. P1075 (0.01-10 μM) induced a concentration-dependent inhibition of both neurogenic contractions, and contractions evoked by exogenous NA of the HSV with pEC 50 values of of 6.48 ″ 0.05 and 6.36″ 0.08. The difference between the pEC 50 values (r) was not statistically significant (P > 0.05). These results suggest that the antivasoconstrictor effect of P1075 on the HSV might be postsynaptic, and associated with opening of the smooth muscle potassium channels.

The repetitive transmural EFS was carried out at 20 Hz with square wave pulses of 0.3 ms duration and supramaximal voltage. The contraction of the HSV in response to transmural EFS recorded in our experiments are neurogenic in nature, as this effect was abolished by tetrodotoxin (1 μM). We have also found that phentolamine (1 μM) inhibited almost completly (90 ″ 2%) the HSV contractions to EFS suggesting that this response was mediated by NA release from perivascular sympathetic nerve endings activating postjuncional α adrenoceptors. P1075 (0.01-10 μM) induced a concentration-dependent inhibition of both neurogenic contractions, and contractions evoked by exogenous NA of the HSV with pEC 50 values of of 6.48 ″ 0.05 and 6.36″ 0.08. The difference between the pEC 50 values (r) was not statistically significant (P > 0.05). These results suggest that the antivasoconstrictor effect of P1075 on the HSV might be postsynaptic, and associated with opening of the smooth muscle potassium channels.",
