Perhaps my wife and I fall into another category: Those who are not sick, who would never have sought out medical attention because of symptoms, but who have discovered they have Lyme almost by accident. For us, taking abx (I'm doing 4 500-mg Biaxin capsules per day plus a couple of Vantin's) is a calculated risk, a choice, hopefully, of the lesser of evils -- the greater evil being gradually consumed by the spirochetes until irreparable damage has been done -- although Mr. , a victim of the Tuscagee syphillis study, lasted (I read here} until the age of 102. Perhaps our lack of symptoms may have something to do with " thick blood " as described below (repeating what was already presented to the list). I have been taking 5 aspirins a day for years because of osteoarthritis (it works for me); and, in addition since 1995, I have been taking coumadin because of atrial fibrillation. My wife has a low platelet count. I concur with the opinion that, at present, there is no cure for Lyme -- only holding actions, which aim to slow destruction, as are used on AIDS victims. Massive government research to develop a cure for Lyme should be a top political priority. Equally important, especially for me, is the development of direct tests for the presence of Lyme in one's body. Our Lyme was discovered with a labelled antibody fluorescence microscopy test developed by Dr. Lida Matman and done at both the Bowen Laboratory in Florida and the Laboratory in Florida -- for addresses and further info, please see http://www.centurytel.net/tjs11/bug/l2.htm I have questions about this test which have not yet been answered, such as what is the exact procedure and where (specific address) do the labelled antibodies come from. Because of the importance of test development, I am also repeating the immediately below submission to the group. Finally, I'm enclosing an article on a promising development in fluorescence microscopy.

The B cells which differentiate into antibody producing cells first produce IgM, then IgG, then IgA to the antigenic components of the agent. Initially, and in certain other instances, the predominance of the antibody may be found bound to the agent in an antigen-antibody or immune complex. Serologic diagnosis of infection with the spirochete Borrelia burgdorferi (Bb), the cause of Lyme disease has been hampered by the variability among existing tests as well as the prolonged time needed for the humoral response to reach thresholds of detection by conventional assays. As specific antibody (Ab) made be found bound to an infectious agent, especially early in the infection, and during active infection, we hypothesized that this could be occurring in Lyme disease. We isolated and dissociated serum immune complexes from Lyme disease patients, fulfilling modified CDC criteria, and controls. Immune complexes were first collected by polyethylene glycol (PEG). Following dissociation by high pH, the dissociated constituents were analyzed by ELISA and Western blots. Specificity of the reactive Ab was evaluated by probing for the target antigen using monoclonal and polyclonal Abs, as well as recombinant proteins. Complexed Ab to Bb was found in 10 of 11 very early cases(p=2 x 10E-7), 55 of 56 (p= or less than 10E-3) symptomatic patients with Lyme disease, 0 of 50 healthy controls, 2 of 50 patients from the endemic areas with other diseases including those likely to have elevated levels of immune complexes, 13 of 13 (p= or less than E-8) persistently seronegative patients who had erythema migrans and a subset of 4 of 4 who were also positive on a T cell proliferative assay to Bb, and 0 of 8 patients who had recovered. In the early acute cases complexed IgM was the first antibody to be detected. Predictive values (PV), based upon a sensitivity of 98% and a specificity of 98% were PV+ of 36% (prevalence of 1%) to 98.6% (prevalence of 50%) and PV- of 99.9% to 99.7% between these prevalences. The data suggest that this relatively simple technique has potential to support or exclude a clinical diagnosis of early as well as active Lyme disease. ------------------------------------------- paleotechnics@... wrote: In response to the possibility that there might be a genetic factor, Berg is proposing a theory that some microbes in some people can throw them into a hypercoagulable state (thick blood) usually due to genetic blood clotting disorder. The coagulation dampens the immune system and prevents you from getting all the way better. Lyme is one of the suspected pathogenes. Treatment is with anti coagulation medication concurent with antibiotics which cleans up the vascular system exposing infectous organisms to antibiotics, and allows the thinned blood to get around where it should. ------------------------------------------- The following article is excerpted from Scince News, 7-22-00: Week of July 22, 2000; Vol. 158, No. 4 Device Sees More inside Live Cells By P. Weiss The delicate touch of visible light allows scientists to peer into living cells without disrupting them. However, to discern the subtlest details, optical microscopes have long been considered too crude a tool. Instead, researchers have developed techniques such as electron microscopy to make out the finest features, but only in dead specimens. Enter the stimulated emission depletion microscope. This novel optical device harmlessly resolves fluorescently labeled bits of living cells that are smaller than the so-called diffraction limit, say its developers at the Max Planck Institute for Biophysical Chemistry in Göttingen, Germany. Because light bends, or diffracts, around the edges of objects, ordinary optical microscopes can discern features no closer than a half-wavelength apart, a distance of 200 nanometers (nm) or so. Beating the diffraction limit, the new prototype instrument can resolve depth to one-sixth of what the best conventional optical microscopes can achieve. Its horizontal resolution comes in under one-half the other instruments' limit, report A. Klar and his colleagues in the July 18 Proceedings of the National Academy of Sciences. Considering all three dimensions, the device can distinguish structures only one-eighteenth the minimum volume discernable by diffraction-limited equipment, the researchers say. " The work by [the Göttingen team] has the potential to transform the fluorescence microscopy 'Renaissance' we are currently experiencing into an 'Enlightenment Millennium,' " says Shimon Weiss of Lawrence Berkeley (Calif.) National Laboratory in a commentary in the same journal issue ... Like other so-called confocal microscopes, the novel instrument works by focusing a laser inside cells tagged with nontoxic fluorescent molecules. By scanning the light across horizontal levels in the cell and then assembling the slices in a computer, researchers can generate a three-dimensional fluorescent image of the cell's interior. Typically, an oblong laser spot created by a confocal microscope has a diffraction-limited size of about 600 nm in depth and 200 nm in girth, says team leader Stefan W. Hell. What enables the new microscope to both beat the diffraction limit and reduce distortion from its oblong spot, he explains, is a one-two combination of laser pulses. The device generates a 0.2-picosecond pulse of green light, which creates the typical oblong illumination. Immediately afterward, it fires an oddly shaped and much longer-lasting red pulse into the area excited by the green pulse. The red squelches fluorescence from the green light anywhere the pulses overlap. Because the second pulse is doughnut-shaped, with blobs of light above and below its doughnut hole, the red light confines fluorescence to a roughly spherical spot 100 nm across. Comparing the green oblong to an American football, Hell says that the final truncated spot resembles a tennis ball. Thanks to that smaller spot size, he adds, the microscope can scan with a finer point and discern unprecedentedly small features. From Science News, Vol. 158, No. 4, July 22, 2000, p. 52.
