With this paper I review the strange unplanned and unexpected trip I’ve had with (Figure 9) (13-15). of alkaloids on rat myocardial contractility (Resource: Modified from research 5). After that we got invited to Ponte Vedra to AG-1024 become listed on the American Climatologic and Clinical Association. The AG-1024 Association got some of these umbrella beverages and offered us an opportunity to review our open fire ant work. Maybe all those fire ants we blenderized over the years would be pleased to know they were remembered before such an august group. DISCUSSION Fire ants pose increasing peril to fauna flora and agriculture in the coastal United States and Puerto Rico where active infestation has already occurred. Their habitat will continue to expand. Invenomization has been associated with cutaneous and systemic allergic reactions acute coronary syndromes cerebrovascular accidents and seizures in humans. No method to stop the expansion of the range of these insects has yet been identified. Since there will be increasing contact between these insects and humans we were anxious to understand the mechanisms for the clinical reactions that occur after invenomization. We now understand that the 5% of the venom AG-1024 that is protein is responsbile for the IgE-mediated immediate and late phase reactions reactions that can be prevented or attenuated by venom immunotherapy. Extracts for this therapy can be easily and inexpensively prepared from live fire ants and contain adequate quantities of fire ant venom to induce a protective immune response. The other 95% of the venom is composed of piperadine alkaloids with a variety of cytotoxic and antibacterial activities. Some are strong inhibitors of nitric acid synthetase. Hopefully the information we AG-1024 have learned about these fascinating insects will contribute to further research on treatment of reactions to invenomization and identify medical applications for venom components including antimicrobial activities now under investigation.

Williams PhD (USDA) Stephen Kemp MD (UMC) and Robin Rockhold PhD (UMC) for their hard work and support. Leigh Wright. BA (UMC) assisted with the production of this manuscript. I would also like to thank the millions of fire ants who have given their last full measure of venom. Footnotes Potential Conflicts of Interest: None disclosed. DISCUSSION Barondess NY: Dr. deShazo that was a wonderful talk. I observed as you remarked that the fireplace ants were generally confined towards the reddish colored locations and I pointed out that there were hardly any in the blue locations; and placing that as well as this last component approximately the decapitating journey I wondered if you want to pull anything broader away of the observations? Deshazo Jackson: Well it’s very problematic for me to accomplish since I might be the just Democrat I understand in the complete condition of Mississippi.
