20.500.12556/RUL-175900 The first subacute study with oral administration of bisphenol AP in male rats cardiovascular data and metabolite detection Bisphenols are frequently used in the plastic industry. However, there is a need for addressing their safety in in vivo studies based on the observed negative impact of bisphenol A. Bisphenol AP (BPAP) is frequently found in the environment, human food, and biological fluids, but its cardiovascular effects have not yet been tested. For this reason, we administered BPAP in a daily single dose of 2.5 mg.kg$^{-12}$ via oral gavage to eight male Wistar Han rats for a period of 4 weeks. Eight control rats received the solvent, sesame oil. Parent BPAP was detectable in plasma only in 3 animals by a validated LC-MS/MS method, whereas its glucuronide was found in all animals (48.4 ± 25.4 nM). Arterial blood pressure did not change during or at the end of the treatment. Some disturbances in cardiac rhythm were observed (e.g., increased heart rate, prolonged P wave and QT$_{peak}$ interval, p < 0.05), but there was no increase in serum cardiac troponin T. Vessels isolated from BPAP-treated animals showed impaired vasodilatory response compared to control animals (p < 0.05). BPAP impacted coagulation and caused hemolysis only in hundreds of µM concentrations. These results demonstrate the potential of BPAP to affect cardiac rhythm and impair vessel homeostasis after subacute exposure. bisphenol endocrine disruptor pollutant hypertension cardiovascular bisfenol endokrini motilci onesnaževalci hipertenzija kardiovaskularni sistem hormonski motilci true false true Angleški jezik Slovenski jezik Članek v reviji 2025-11-13 11:26:55 2025-11-13 11:27:02 2025-12-16 03:50:11 0000-00-00 00:00:00 2025 0 0 9 str. art. 119143 Vol. 304 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 612.43:620.266.1 0147-6513 10.1016/j.ecoenv.2025.119143 251567875 1-s2.0-S0147651325014885-main.pdf 1-s2.0-S0147651325014885-main.pdf 1 471D0DB22A3F53932347156EDA3D34FA efba9c806e856fdb54908c3a4815a9fb32e062a46e193c25aac191257d02cc6f ace0c86f-c07b-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=221851 https://www.sciencedirect.com/science/article/pii/S0147651325014885 1 f69f8f15-c07a-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=221850 Fakulteta za farmacijo 0 0 0
