This project has determined whether pirfenidone, a new antifibrotic compound, and spironolactone, an aldosterone antagonist, reverse both deposition of the major extracellular matrix proteins, collagen and fibronectin, and functional changes in the streptozotocin(STZ)\u2010diabetic rat.<\/jats:p><\/jats:list-item>\n<jats:list-item><jats:p>Streptozotocin (65\u2003mg\u2003kg<jats:sup>\u22121<\/jats:sup> i.v.)\u2010treated rats given pirfenidone (5\u2010methyl\u20101\u2010phenyl\u20102\u2010[1H]\u2010pyridone; approximately 200\u2003mg\u2003kg<jats:sup>\u22121<\/jats:sup>\u2003day<jats:sup>\u22121<\/jats:sup> as 0.2\u20132g 1<jats:sup>\u22121<\/jats:sup> drinking water) or spironolactone (50\u2003mg\u2003kg<jats:sup>\u22121<\/jats:sup>\u2003day<jats:sup>\u22121<\/jats:sup> s.c.) for 4 weeks starting 4 weeks after STZ showed no attenuation of the increased blood glucose concentrations and increased food and water intakes which characterize diabetes in this model.<\/jats:p><\/jats:list-item>\n<jats:list-item><jats:p>STZ\u2010treatment increased perivascular and interstitial collagen deposition in the left ventricle and kidney, and surrounding the aorta. Cardiac, renal and plasma fibronectin concentrations increased in STZ\u2010diabetic rats. Passive diastolic stiffness increased in isolated hearts from STZ\u2010diabetic rats. Both pirfenidone and spironolactone treatment attenuated these increases without normalizing the decreased +dP\/dt<jats:sub>max<\/jats:sub> of STZ\u2010diabetic hearts.<\/jats:p><\/jats:list-item>\n<jats:list-item><jats:p>Left ventricular papillary muscles from STZ\u2010treated rats showed decreased maximal positive inotropic responses to noradrenaline, EMD 57033 (calcium sensitizer) and calcium chloride; this was not reversed by pirfenidone or spironolactone treatment. STZ\u2010treatment transiently decreased GFR and urine flow rates in isolated perfused kidneys; pirfenidone but not spironolactone prevented the return to control values.<\/jats:p><\/jats:list-item>\n<jats:list-item><jats:p>Thus, short\u2010term pirfenidone and spironolactone treatment reversed cardiac and renal fibrosis and attenuated the increased diastolic stiffness without normalizing cardiac contractility or renal function in STZ\u2010diabetic rats.<\/jats:p><\/jats:list-item>\n<\/jats:list>\n<\/jats:p><jats:p><jats:italic>British Journal of Pharmacology<\/jats:italic> (2001) <jats:bold>133<\/jats:bold>, 687\u2013694; doi:<jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"doi\" xlink:href=\"10.1038\/sj.bjp.0704131\">10.1038\/sj.bjp.0704131<\/jats:ext-link><\/jats:p>","DOI":"10.1038\/sj.bjp.0704131","type":"journal-article","created":{"date-parts":[[2005,1,28]],"date-time":"2005-01-28T21:31:17Z","timestamp":1106947877000},"page":"687-694","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":179,"title":["Reversal of cardiac and renal fibrosis by pirfenidone and spironolactone in streptozotocin\u2010diabetic rats"],"prefix":"10.1111","volume":"133","author":[{"given":"Goran","family":"Miric","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catherine","family":"Dallemagne","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zoltan","family":"Endre","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Solomon","family":"Margolin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen M","family":"Taylor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lindsay","family":"Brown","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,1,29]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0008-6363(97)00073-4"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.ATV.17.6.1152"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/cvr\/26.7.671"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00167222"},{"key":"e_1_2_6_6_1","first-page":"S143","article-title":"Reversal of cardiac fibrosis in deoxycorticosterone acetate\u2010salt hypertensive rats by inhibition of the renin\u2010angiotensin system","volume":"10","author":"BROWN L.","year":"1999","journal-title":"J.
