NIDA, the NIH's Office of AIDS Research, the World Health Organization/Programme on Substance Abuse (WHO/PSA), and the Joint United Nations Programme on HIV/AIDS teamed together in sponsoring the inaugural meeting of the Global Research Network on HIV Prevention in Drug-Using Populations, held June 25-26, 1998 in Geneva, Switzerland, just prior to the 1998 World AIDS Conference. The meeting represented the first step toward the long-term goal of establishing a self-sustaining global communications infrastructure for rapid international communication, dissemination, and utilization of HIV/AIDS epidemiology and prevention research information, including the exchange and interpretation of research findings from intervention studies with drug-using populations at high risk for HIV and other blood-borne diseases; the translation and dissemination of research findings on prevention principles and practices which slow the rate of spread of HIV; and the development of new cross-national, collaborative research efforts to prevent the spread of HIV and other infections among drug users. The international participants at the meeting represented more than 25 countries and every region of the world. Dr. Richard H. Needle, Chief of NIDA's Community Research Branch, took the lead in planning, organizing, and chairing the inaugural meeting. Also participating in the meeting for NIDA were Dr. Zili Sloboda and Helen Cesari, DEPR, and Patricia Needle, NIDA International Program.

Mr. Nicholas Kozel, DEPR, co-chaired a joint meeting of the East and South Asian Multi-City Epidemiology Work Group meeting held in Penang, Malaysia on May 4-7, 1998. Researchers from Malaysia, the Philippines, Thailand, Burma, China, Laos, Cambodia, Vietnam, Bangladesh, India, Pakistan, and Sri Lanka participated in the meeting and reported on patterns and trends of drug abuse in their countries and on emerging problems and related issues. Major drugs of abuse include: opium smoking and injection, heroin injection and ‘chasing the dragon', buprenorphine injection, cannabis smoking, inhalation of volatile substances, and the recent and substantial emergence of methamphetamine, MDMA and ketamine abuse in a number of countries in the region.

Ms. Ann Blanken, Deputy Director, DEPR, represented NIDA at the 28th meeting of the Pompidou Group of substance abuse epidemiologists June 8-9, 1998 at the Council of Europe in Strasbourg, France.

On July 25, 1998, Dr. Tsung-Ping Su of the IRP was chosen by the International Narcotic Research Conference (INRC), to participate in a symposium entitled "Opioids in Development and Apoptosis" and present a talk entitled "Delta Opioid DADLE Blocks Dopamine Transporter (DAT) Loss and p53 mRNA Increase Induced by Methamphetamine (METH): By Acting as a Free Radical Scavenger?" at Garmisch Partenkirchen, Germany.

Dr. Svetlana Chefer, IRP, presented a paper on nicotinic and dopamine receptors in monkey brain at the 12th General Meeting of the European Society for Neurochemistry held in St. Petersburg, Russia, July 19-24, 1998.

Dr. Jean Lud Cadet, Clinical Director of the IRP, recently attended the meeting of the European Society for Neurochemistry in St. Petersburg, Russia. There, he presented data on the effects of methamphetamine-induced neurotoxicity. This was contrasted to the neurotoxic effects of dopamine which was shown by Dr. Cadet's group to cause apoptosis. These data support the idea that methamphetamine is causing its effects through the increase release of dopamine in the brain.
