Material compatibility, product ratings and application details should be considered in the selection. The same was true in an investigation of rhesus monkeys given daily intravenous doses of 3 g/kg 40% DMSO for 9 consecutive days. 3. Radioactive tracer studies of DMSO absorption in humans found that 5 minutes after cutaneous application, DMSO is detectable in the blood; after 1 hour, it is detectable in the bones.12, The free electron pairs of its oxygen atoms allow DMSO molecules to transfer electrons and accept hydrogen bonds. MSM or DMSO2 is probably also available in health food stores. !eF]q7F In the experimental group, an 80% solution of DMSO gel was topically applied at 1 g/kg daily to 65 subjects for 14 days and to another 40 subjects for 90 days. It seems reasonable to try DMSO when other more traditional methods of improving circulation, such as releasing tension, relieving kinks from pedicles, or decreasing pressure, have failed.

Further, DMSO has so many possibilities that it does not easily fit into a drug category. Several animal studies have explored the analgesic action of DMSO,13,15,16 which seems to block peripheral nerve C fibers.17 One study found that DMSO was not only as effective as morphine for pain relief, but that its effect persisted several hours longer than that of morphine.18 DMSO also has been used around the world for decades as a topical analgesic for treatment of arthritis pain. endobj endobj WebChemical Compatibility Database Begin Compatibility Search: CHEMICAL TO MATERIAL CHEMICAL TO CHEMICAL Use dropdowns below to select a Chemical, and compare against ALL MATERIALS or any specific material. If two substances form a layer, they are clearly immiscible. Dimethyl sulfoxide [(CH3)2SO] (DMSO) is an organic solvent of which plastic surgeons should be aware, primarily because its ability to increase perfusion has led to its use in decreasing ischemia in tissue flaps.

Your session has expired. In 1961, nearly a century after its synthesis, investigations into possible medical applications of DMSO began when Dr. Stanley Jacob, then head of the organ transplant program at Oregon Health Sciences University, was looking for substances that might be effective as organ preservatives.1 Jacob noticed that DMSO rapidly, but harmlessly, penetrated deep into his skin.

The lens trouble in lower mammals was sufficient evidence for the FDA to conclude that DMSO was highly toxic, and almost all United States-based research was stopped. DMSO with H2O2 was studied because H2O2 stimulates the release of oxygen when applied to tissues, and DMSO penetrates cell membranes; so, theoretically, DMSO could deliver hydrogen peroxide throughout the flap. 1. Dr. Stanley Jacob, considered the father of DMSO research, markets MSM and oral DMSO on his Web site (www.jacoblab.com) as a nutritional sulfur supplement ingested in liquid or crystal form.
