DMSO may have anti-inflammatory, antioxidant and analgesic activities. DMSO also readily penetrates cellular membranes.
PDR for Nutritional Supplements 2nd ed. Thomson Reuters, Montvale, NJ 2008, p. 187
EXPL THER OBJECTIVE: To evaluate the discomfort and long-term efficacy associated with instillation of dimethyl sulfoxide (DMSO). MATERIAL AND METHODS: A total of 28 patients, 13 (11 females, 2 males) with classic interstitial cystitis (IC) and 15 (13 females, two males) with non-ulcer disease, who had received at least one series of six instillations of DMSO were studied. In addition to studying micturition diaries before and after the treatment, the evaluation included assessments of pain using a visual analog scale and of side-effects after each instillation in every series. Data were obtained by surveying the clinical records. A follow-up telephone interview was conducted for those patients who were treated with DMSO and in whom the treatment was considered successful. DMSO instillations were considered successful if the patient reported symptom amelioration and chose to continue with the treatment. RESULTS: Side-effects were not more common or pronounced in patients with classic compared to non-ulcer IC. For classic IC a significant difference could be seen when comparing side-effects experienced during the first three instillations and the three subsequent instillations. After DMSO instillations, a residual treatment effect lasting 16-72 months could be seen. CONCLUSIONS: Intravesical instillation therapy with DMSO appears to be a feasible treatment option for both subtypes of IC and is associated with a reasonably low degree of discomfort.

Onyx injection is a new technique for embolization of cerebral aneurysms that is involved in a controversy about the 'toxicity' of its solvent, dimethyl sulfoxide (DMSO). /The study/ retrospectively studied 38 patients treated for aneurysms with the liquid polymer, Onyx. Induction was with propofol, fentanyl and vecuronium, and anesthesia was maintained with isoflurane in O2 and N2O. The patients were given 500 mL of fluid after induction, and bradycardia was prevented in order to keep patients hyperdynamic. Electrocardiography (ECG), non-invasive blood pressure (NIBP), pulse oximetry, core temperatures, invasive blood pressure (BP), etCO2, and urine output were monitored throughout the intervention. Heart rate and BP changes in response to balloon inflation, DMSO injection, Onyx injection and balloon deflation were recorded. The patients were followed with serial neurological examinations, computerized tomography and/or magnetic resonance imaging postoperatively for evidence of any neurological injury. Cumulative DMSO doses were always well under previously implicated doses for systemic toxicity. No changes implicating toxic reactions were observed during DMSO and Onyx injections. Balloon-induced changes returned to baseline within 1 min of balloon deflation. Technique-related permanent morbidity occurred in two patients (worsening of cranial nerve palsies in one and monocular blindness in another) and intracranial hemorrhage with resulting death in one patient. All patients showed a tendency to oxygen desaturation, but this finding did not cause any clinical consequence. Anesthesiologists need to be vigilant in monitoring patients treated with techniques that are new or are being developed. /The study/ have seen no evidence of toxicity or any anesthetic complications in our group of patients, our only clinical concern being a tendency to oxygen desaturation, which may be explained by the inhalational elimination of DMSO.

/This study/ describe/s/ the occurrence of the trigeminocardiac reflex (TCR) during DMSO pre-flushing of the microcatheter in preparation for Onyx embolization via the internal maxillary artery. TCR has not been previously associated with embolization of extradural entities. Familiarity with this clinical reflex and its proper management may help in planning neurointerventional procedures involving DMSO injection in the trigeminal territory.

For the symptomatic relief of patients with interstitial cystitis.
Dimethyl Sulfoxide may have anti-inflammatory, antioxidant and analgesic activities. Dimethyl Sulfoxide also readily penetrates cellular membranes. The membrane-penetrating ability of dimethyl sulfoxide may enhance diffusion of other substances through the skin. For this reason, mixtures of idoxuridine and dimethyl sulfoxide have been used for topical treatment of herpes zoster in the United Kingdom.

By use of a Fourier transform infrared (FTIR) spectroscopic imaging technique, /this study examined/ the dynamic optical clearing processes occurring in hyperosmotically biocompatible agents penetrating into skin tissue in vitro. The sequential collection of images in a time series provides an opportunity to assess penetration kinetics of dimethyl sulphoxide (DMSO) and glycerol beneath the surface of skin tissue over time. From 2-D IR spectroscopic images and 3-D false color diagrams, ...show/s/ that glycerol takes at least 30 min to finally penetrate the layer of epidermis, while DMSO can be detected in epidermis after only 4 min of being topically applied over stratum corneum sides of porcine skin. The results demonstrate the potential of a FTIR spectroscopic imaging technique as an analytical tool for the study of dynamic optical clearing effects when the bio-tissue is impregnated by hyperosmotically biocompatible agents such as glycerol and DMSO.

Autoimmune strain MRL/Ipr, C3H/lpr, and male BXSB mice were placed on a continuous treatment regimen with 3% DMSO or 3% DMS02 in the drinking water, ad libitum, commencing at 1 to 2 months of age, before spontaneous autoimmune lymphoproliferative disease development could be detected. This represented doses of 8-10 g/kg/day of DMSO and 6-8 g/kg/day of DMS02. Both compounds were observed to extend the mean life span of MRL/Ipr mice from 5.5 months to over 10 months of age. All strains showed decreased antinuclear antibody responses and significant diminution of lymphadenopathy, splenomegaly, and anemia development. Serum IgG levels and spleen IgM antibody plaque formation, however, did not differ from control values. There was no indication of involvement of systemic immunosuppressive or antiproliferative effects, and treated animals were observed to remain healthy and vigorous with no signs of toxicity. These results demonstrate that high doses of both DMSO and its major in vivo metabolite, DMSO2, provide significant protection against the development of murine autoimmune lymphoproliferative disease.

The mechanism of dimethyl sulfoxide's actions is not well understood. Dimethyl sulfoxide has demonstrated antioxidant activity in certain biological settings. For example, the cardiovascular protective effect of dimethyl sulfoxide in copper-deficient rats is thought to occur by an antioxidant mechanism. It is also thought that dimethyl sulfoxide's possible anti-inflammatory activity is due to antioxidant action.
Thioacetamide (400 mg/kg body weight, i.p.) was administered to rats. After 12 hr the activity of plasma glutamate-oxaloacetate transaminase (GOT) and glutamate-pyruvate transaminase (GPT) was significantly higher than that of the control group, and after 24 hr plasma GOT and GPT activities strongly increased. These results indicated that the necrotic process was initiated at about 12 hr and developed thereafter. By co-administration of dimethyl sulphoxide (DMSO, 18 and 1 hr before, and 8 hr after administration of thioacetamide: each time, 2.5 mL/kg body weight, p.o.), plasma GOT and GPT were significantly decreased and were even comparable to the control group, showing that DMSO totally prevented the necrotic action of thioacetamide. After 12 and 24 hr of thioacetamide administration, the hepatic level of vitamin C, the most sensitive chemical indicator of oxidative stress, decreased significantly, indicating that oxidative stress was significantly enhanced 12 hr after thioacetamide intoxication and thereafter. DMSO totally restored the liver vitamin C level, demonstrating that DMSO effectively ameliorated the oxidative stress caused by thioacetamide, resulting in the prevention of necrosis of the liver. Phosphorylated c-Jun NH(2)-terminal kinase (JNK) significantly increased transiently 12 hr after treatment with thioacetamide. These results indicated that oxidative stress and the activation of JNK took place almost simultaneously. Phosphorylated extracellular signal-related kinase (ERK) 2 was significantly increased 6-12 hr after thioacetamide injection. Phosphorylated p38 MAPK (mitogen activated protein kinase) was significantly decreased 24 hr after administration of thioacetamide. DMSO treatment inhibited the change of these MAPKs by thioacetamide, corresponding with the prevention of the liver necrosis as well as the attenuation of oxidative stress.

Previous studies performed in our laboratory indicated that non-toxic concentrations of peroxynitrite nevertheless commit U937 cells to a rapid necrosis that is however prevented by a survival signaling driven by cytosolic phospholipase A(2)-released arachidonic acid. Toxicity was mediated by concentrations of peroxynitrite resulting in H(2)O(2)-dependent inhibition of arachidonic acid release. The present study shows that U937 cells differentiated to monocytes by prolonged exposure to dimethyl sulfoxide are resistant to peroxynitrite because able to respond with enhanced release of arachidonic acid. An additional important observation was that these cells require more arachidonate than the undifferentiated cells to support the survival signaling. The enhanced arachidonic acid release was not associated with changes in cytosolic phospholipase A(2) expression but was rather dependent on the increased responsiveness of the enzyme to calcium-dependent stimulation as well as on reduced mitochondrial formation of H(2)O(2). The latter event was found to be critical, since differentiated and undifferentiated cells were equally sensitive to peroxynitrite when the accumulation of H(2)O(2) was enhanced via depletion of catalase, or addition of a complex III inhibitor. Thus, the strategy selected by the differentiation process to allow monocytes to cope with peroxynitrite appears to involve some specific mechanism preventing the mitochondrial formation of H(2)O(2).

Dimethyl sulfoxide (DMSO) has recently been proposed as an anti-inflammatory and free radical scavenging agent. However, the mechanisms by which DMSO mediates its therapeutic effects are unclear. /This paper/ investigated the capability of DMSO to up-regulate heme oxygenase-1(HO-1) expression, as well as the possible underlying mechanisms in human umbilical vein endothelial cells (HUVECs). DMSO induced HO-1 expression both at the level of mRNA and protein in dose-and time-dependent manners in HUVECs, resulting in increased HO-1 activity. The pharmacological inhibition of cJun-N-terminal kinases (JNKs) blocked the DMSO-induced HO-1 up-regulation, while inhibition of extracellular regulated kinase and p38-MAPK did not block heme oxygenase-1 up-regulation. In addition, the phosphorylation of JNKs was initiated by DMSO, indicating the involvement of this kinase in the observed response. DMSO increased the nuclear translocation of NF-E2-related factor 2 (Nrf2) and enhanced its binding to the anti-oxidant response element. Inhibition of Nrf2 synthesis by small interfering RNA molecules subsequently inhibited HO-1 expression induced by DMSO, indicating DMSO's role in inducing HO-1 expression via Nrf2 activation. Utilizing these findings, the present study identified DMSO as a novel inducer of HO-1 expression and identified the underlying mechanisms involved in this process.

Dimethyl sulfoxide (DMSO) is evident to induce apoptosis in certain tumor cells in vitro. However, its apoptotic mechanism remains unexplored in in vivo tumors. This article describes that DMSO, being non-toxic to the normal lymphocytes, up regulated TNFalpha and p53, declined Bcl-2/Bax ratio, activated caspase 9 and PARP-1 cleavage and produced apoptotic pattern of DNA ladder in Dalton's lymphoma (DL) in vivo. This was consistent with the declined expressions of tumor growth supportive glycolytic enzymes; inducible D-fructose-6-phosphate-2-kinase and lactate dehydrogenase-5 in the DL cells. The findings suggest induction of TNFalpha-p53-mitochondrial pathway of apoptosis by DMSO in a non-Hodgkin's lymphoma and support evolving concept of glycolytic inhibition led apoptosis in a tumor cell in vivo.
