The alpha-2 adrenoceptor agonists, clonidine, guanabenz, and guanfacine, injected subcutaneously ... more The alpha-2 adrenoceptor agonists, clonidine, guanabenz, and guanfacine, injected subcutaneously produced a dose-related diuresis. The maximal effect occurred at 2h after administration of clonidine 192 micrograms/kg or 960 micrograms/kg of guanabenz and guanfacine. The alpha-2 antagonist, yohimbine, in doses of 1-8 mg/kg administered prior to the agonists caused a dose-dependent decrease in urine output. The action of the three agonists at alpha-2 adrenoceptors was supported by the observation that the alpha-1 adrenoceptor agonist, prazosin (0.61-2.5 mg/kg), administered prior to each agonist caused an inconsistent decrease in the elevated urinary output caused by clonidine, guanabenz and guanfacine. These results indicate that stimulation of alpha-2 adrenoceptors causes diuresis in the rat.

To date, 17 studies have been completed, 12 are ongoing, and 12 are currently planned. Under the direction of the Substance-Specific Applied Research Program (SSARP), ATSDR-supported research has filled research needs that significantly improved the information base available for making appropriate public health decisions. With the knowledge and understanding gained from this research, health professionals are better able to identify and interdict significant exposure and mitigate toxicity when exposure occurs. Thus, the SSARP has played, and continues to play, a vital role in contributing towards improving ATSDR's efforts to meet its mission and goals in environmental public health. In addition to addressing research needs of interest to ATSDR, findings from the program have contributed to the overall scientific knowledge about the effects of toxic substances in the environment.

In accordance with the Pandemic and All-Hazards Preparedness Act mandating new public health systems research for preparedness and emergency response, CDC provided competitive awards establishing nine Preparedness and Emergency Response Research Centers (PERRCs) in accredited U.S. schools of public health. The PERRCs conducted research in four IOM-recommended priority areas: (1) enhancing the usefulness of public health preparedness and response (PHPR) training, (2) creating and maintaining sustainable preparedness and response systems, (3) improving PHPR communications, and (4) identifying evaluation criteria and metrics to improve PHPR for all hazards. The PERRCs worked closely with state and local public health, community partners, and advisory committees to produce practice-relevant research findings. PERRC research has generated more than 130 peer-reviewed publications and nearly 80 practice and policy tools and recommendations with the potential to significantly enhance our nation's PHPR to all hazards and that highlight the need for further improvements in public health systems.
