Abstract
The contribution of air pollution-induced cardiopulmonary damage on the development of hypertensive disorders of pregnancy and other adverse outcomes of pregnancy has gained increased attention as epidemiological data continue to highlight spatiotemporal pregnancy trends related to air pollution exposure. However clinical mechanistic data surrounding gestational complications remain sparse, necessitating the need for the use of animal models to study these types of complications of pregnancy. The current study seeks to examine the real-time effects of mid-gestational ozone exposure on maternal blood pressure and body temperature through the use of radiotelemetry in a rat model. The exposure resulted in acute depression of heart rate and core body temperature as compared to control animals. Ozone-exposed animals also presented with a slight but significant increase in arterial blood pressure which was perpetuated until term. The data presented here illustrates the feasibility of murine models to assess cardiovascular complications caused by inhaled toxicants during the window of pregnancy.
期刊介绍:
Cardiovascular Toxicology is the only journal dedicated to publishing contemporary issues, timely reviews, and experimental and clinical data on toxicological aspects of cardiovascular disease. CT publishes papers that will elucidate the effects, molecular mechanisms, and signaling pathways of environmental toxicants on the cardiovascular system. Also covered are the detrimental effects of new cardiovascular drugs, and cardiovascular effects of non-cardiovascular drugs, anti-cancer chemotherapy, and gene therapy. In addition, Cardiovascular Toxicology reports safety and toxicological data on new cardiovascular and non-cardiovascular drugs.
