March, 2000 Greetings, An email glitch may have prevented this from being sent. We apologize if you get this twice. Dr. Terry Sweeney of Genentech, San Francisco, CA, has chosen the Inhalation Toxicology Program at the University of Hawaii as the recipient of the InTox Inhalation System. The program Director, Dr. Bill Mautz, who did his Doctoral work at UC Irvine, now heads this NIEHS-sponsored program. Dr. Sweeney thanks those who sent requests for this donation. This is the sixth issue of the inhalation toxicology newsletter. Submissions should be sent before the end of each month to assure inclusion. If you received this email twice or if you previously requested removal of your name but you "reappeared", please accept our apologies. We have received additional names and subscriptions; thus, some replication/duplication may have occurred. To add or have your name deleted from our subscriber list, see the section entitled, Additions, Changes and Removals, at the end of this message. If you find this forum useful, send our web address or email a copy of the newsletter to a colleague. Inhalation Toxicology Forum Dr. Doug Cooper prepared the following two items:
He mathematically describes this process so that the "Aerosol Cannon" phenomenon can be avoided. http://www.inhalation.net/turbulent_mixing.htm
In this second article, Doug offers a companion piece on diluters with a discussion on the problems of using flow metering devices that are susceptible to particle entrapment. His solution is to filter the aerosol before measuring the flow, where possible http://www.inhalation.net/diluter.htm Mucus Flow Arlene Weiss summarizes a paper by Paul Schlosser of CIIT on the relative roles of convection and chemical reactivity for the disposition of ozone and formaldehyde in nasal mucus and the relative importance of the mucous layer lining the upper respiratory tract. http://www.inhalation.net/mucus_flow.htm In Memoriam Our colleague, former NYU Professor, Dr. Joan M. Daisey, has died in California. Details about her life and research activities can be found by searching the following site: The obituary that was posted at that site appears to no longer be available. Calendar of Upcoming Events: Terry Gordon of the Nelson Institute of Environmental Medicine informs us that the First Amdur Lecture will feature Dr. Eula Bingham, University of Cincinnati. The talk, which will be given in Sterling Forest at the A. J. Lanza Laboratory, will be given on May 12, 2000. Details will be available later this month directly from him. His email address is "terry.gordon@env.med.nyu.edu". Additional events and details can also be found on our calender of events which is found at at: http://www.inhalation.net/calendar.htm SOT Meeting Events CH Technologies booth We are at booth number 228 near the poster presentations area. Buxco will be at booth number 229 across the aisle. For our Canadian Colleagues, the Society of Toxicology of Canada is located at booth number 216. The INHALATION.NET staff welcomes the Canadian representatives. Come visit with us if you have the time. An assortment of chocolates will be available for those who didn't get enough calories on St. Valentine's Day. NYU Alumnae Dinner at the SOT Josh Gurman is organizing NYU Night at SOT this year. The date is Monday, March 20th, 2000 at 7:30 PM at the Sansom Street Oyster House 15th and Sansom Street (about a 10-15 minute walk from the Convention Center) Philadelphia. RSVP: NO LATER THAN WEDNESDAY, FRIDAY, MARCH 15 to Josh Gurman at 201-794-2421 or jgurman@lonza-us.com (if the lonza-us.com does not work try lonza_us.com). Other groups wishing to list their meeting times should send last minute notices to Dr. Sue Shami, the Inhalation Webmaster, for posting in the calender section. She will be on duty at the website throughout the SOT meeting and is available to those of you who remain connected while on the road. WIL RESEARCH Wil Research will present their work on restraint duration with nose-only inhalation exposure and its lack of effect in pregnant rats (abstract 956). They will report their use of a CH Technologies nose-only inhalation system with open style inhalation exposure tubes. A Recent Publication (Primedica Argus) Absence of Testicular Atrophy in a Nose-Only Inhalation Exposure Study A recent publication by Rotherberg et al. (Toxicological Sciences 53:127-134, 2000) verified that male rats held in sealed exposure tubes showed no evidence of testicular atrophy as a result of their restraint. Dr. Susan Shami has prepared a summary of this work. It is found at: http://www.inhalation.net/testicular_atrophy.htm CH Technologies (Booth number 228) will display a selection of sealed and open tubes. One of these, a sealed rodent exposure tube with improved heat transfer characteristics and an innovative sealing system be available for examination. Stop by the booth for details. Comments and Letters to the Editor The Editorial staff welcomes your questions and comments. Send email and any news articles to the Editor at Sponsors Additions, Changes and Removals If a colleague wishes to be added to the mailing list, send email to "Susan Jaeger" <loppa@bellatlantic.net Place the word "SUBSCRIBE" in the subject line. Other pertinent information or comments may appear in the message section. For removal from the email list, just include the word "REMOVE" in the subject line. Our list has recently seen a large number of additions. If you previously asked to be removed but have reappeared, please accept our apologies. We trust this will not be a common occurrence and request your forbearance. For you who ask about the name loppa' in Susan Jaeger's email address, the word Loppa' literally means "bedbug". It is a small, oddly shaped island and bird sanctuary off the Norwegian Atlantic coast, north of the Arctic Circle, below Hammerfest but above Tr ms . The nearest city is Alta which is 20 or so nautical miles away by water. The island is partly owned by Norway and part privately. It is home to many species of Puffins, Terns and Ptarmigan. The local industry consists of bird watching and catching wild Salmon. Susan ancestors, the Ulich family, owned the island at the end of the last century. Ask her about her family history in Finnmark when you see her at the SOT meeting. Most important, ask how she got there since the Hurtrigruten' only passes by; it doesn't stop (except if you ask and then only at sea). She will have an interesting story to tell you. Mea Culpa The Editor-in-Chief apologizes to Dr. David Bernstein for misspelling his name in the last issue of the newsletter. Over qualified people shouldn't type final copy.
