This cardiovascular response is brought about by the activation of the sympathoadrenal system and is accompanied by grooming behavior. To address the role of oxytocinergic pathways in the brain in the mediation of these responses, we investigated the effects of central pretreatment of rats with oxytocin antisense, mixed base, and sense oligodeoxynucleotides on mean arterial pressure, heart rate, and grooming behavior induced by intracerebroventricular injections of substance P (50 pmol). Central pretreatment of conscious rats with the oxytocin antisense oligodeoxynucleotide (intracerebroventricular injections, 8 and 4 hours before administration of substance P) attenuated the mean arterial pressure (by 55%) and heart rate responses (by 58%) as well as grooming behavior induced by the peptide. A complete recovery of all substance P-induced responses was observed 28 hours after antisense oligodeoxynucleotide pretreatment. Intracerebroventricular pretreatment of rats with mixed base and sense oligodeoxynucleotides did not affect the cardiovascular and behavioral responses to substance P. The signal for oxytocin mRNA in the paraventricular nucleus was reduced only in rats pretreated with the antisense oligodeoxynucleotide. These results demonstrate that oxytocin neurons in the paraventricular nucleus, which innervate the cardiovascular centers in the hindbrain and the spinal cord, mediate the increases in blood pressure and heart rate induced by stimulation of substance P receptors in the forebrain. These neurons may also transmit signals, which are generated by substance P in the hypothalamus and are responsible for the sympathoadrenal activation in response to stress.<\/jats:p>","DOI":"10.1161\/01.hyp.31.1.480","type":"journal-article","created":{"date-parts":[[2012,6,12]],"date-time":"2012-06-12T00:53:46Z","timestamp":1339462426000},"page":"480-486","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":21,"title":["Oxytocin Pathways Mediate the Cardiovascular and Behavioral Responses to Substance P in the Rat Brain"],"prefix":"10.1161","volume":"31","author":[{"given":"Tanja","family":"Maier","sequence":"first","affiliation":[{"name":"From the Institute of Pharmacology, Christian-Albrechts University of Kiel, Kiel, Germany (T.M., W.-J.D., T.C., T.U., J.C.) and the Institute of Anatomy II, Friedrich-Schiller University of Jena, Jena, Germany (G.F.J.)."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wen-Jie","family":"Dai","sequence":"additional","affiliation":[{"name":"From the Institute of Pharmacology, Christian-Albrechts University of Kiel, Kiel, Germany (T.M., W.-J.D., T.C., T.U., J.C.) and the Institute of Anatomy II, Friedrich-Schiller University of Jena, Jena, Germany (G.F.J.)."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tama\u0301s","family":"Csiko\u0301s","sequence":"additional","affiliation":[{"name":"From the Institute of Pharmacology, Christian-Albrechts University of Kiel, Kiel, Germany (T.M., W.-J.D., T.C., T.U., J.C.) and the Institute of Anatomy II, Friedrich-Schiller University of Jena, Jena, Germany (G.F.J.)."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gustav F.","family":"Jirikowski","sequence":"additional","affiliation":[{"name":"From the Institute of Pharmacology, Christian-Albrechts University of Kiel, Kiel, Germany (T.M., W.-J.D., T.C., T.U., J.C.) and the Institute of Anatomy II, Friedrich-Schiller University of Jena, Jena, Germany (G.F.J.)."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Unger","sequence":"additional","affiliation":[{"name":"From the Institute of Pharmacology, Christian-Albrechts University of Kiel, Kiel, Germany (T.M., W.-J.D., T.C., T.U., J.C.) and the Institute of Anatomy II, Friedrich-Schiller University of Jena, Jena, Germany (G.F.J.)."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juraj","family":"Culman","sequence":"additional","affiliation":[{"name":"From the Institute of Pharmacology, Christian-Albrechts University of Kiel, Kiel, Germany (T.M., W.-J.D., T.C., T.U., J.C.) and the Institute of Anatomy II, Friedrich-Schiller University of Jena, Jena, Germany (G.F.J.)."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"e_1_3_2_1_2","first-page":"I-38","volume":"18","year":"1991","unstructured":"Ferrario CM, Averill DB.
