Background: Dimethyl Sulfoxide (DMSO) is a solvent most broadly used as a cryopreservative agent. Antitumor effects of DMSO is a recently recognized phenomenon. In this study, cytotoxic effects of DMSO on human monocytes and T leukemic cell lines has been investigated in vitro. Methods: Human leukemic T cells (Molt-4 and Jurkat) and monocytes (U937 and THP1) were cultured in complete RPMI medi...

Dimethyl sulfoxide (DMSO) is reported to induce hepatocyte redifferentiation. The impact of DMSO on liver transcription factors, cytochromes P450 (CYPs), and nuclear receptors regulating CYP expression was assayed in primary rat hepatocytes by QPCR. CYP 2B1, 3A1, and 4A1 mRNAs were reduced to 10-30% of initial liver levels without DMSO and restored at or above liver levels by DMSO treatment. In...

Dimethyl sulfoxide (DMSO) is an efficient solvent for water-insoluble compounds, widely used in biological studies and as a vehicle for drug therapy, but few data on its neurotoxic or behavioural effects is available. The aim of this work is to explore DMSO's effects upon sleep/wake states. Twenty male rats were sterotaxically prepared for polysomnography. Four concentrations of DMSO (5%, 10%, ...

Erythropoietin (Epo) and dimethyl sulfoxide (DMSO) are believed to induce the differentiation of transformed erythroid cells by different signal transduction pathways. We have now obtained evidence for the interaction of these pathways. We used a Rauscher murine erythroleukemia cell line with a relatively low (8% to 10%) hemoglobinization response to Epo alone. Pretreatment of these cells for 1...

Nimodipine and dimethyl sulfoxide (DMSO) were tested (alone and in combination) regarding their ability to increase hypoxic tolerance of brain slices under 'hypoxic' (deprivation of oxygen) or 'ischemic' (hypoxia+withdrawal of glucose) conditions. Direct current (DC) and evoked potentials were recorded in the CA1 region of hippocampal slices of adult guinea pigs. After induction of hypoxia or i...

This study evaluated the influence of dimethyl sulfoxide (DMSO) daily supplementation on diminazene treatment of trypanosomosis. Four groups of Trypanosoma brucei brucei infected rats received 7.0 mg/kg diminazene aceturate on day 7 post infection. Three of the four groups received different doses of DMSO (0.5, 1.0 and 2.0 g/kg, respectively) in addition to diminazene treatment. The changes in ...

Methane (CH(4)) production from the anti-inflammatory agent, dimethyl sulfoxide (DMSO), was used to measure .OH from chemical reactions or human phagocytes. Reactions producing .OH (xanthine/xanthine oxidase or Fe(++)/EDTA/H(2)O(2)) generated CH(4) from DMSO, whereas reactions yielding primarily O-(2) or H(2)O(2) failed to produce CH(4). Neutrophils (PMN), monocytes, and alveolar macrophages al...

This study investigated the effects of hyperbaric oxygen therapy (HBOT) and dimethyl sulfoxide (DMSO) in tissue necrosis, genotoxicity, and cell apoptosis. Random skin flaps were made in 50 male Wistar rats, randomly divided into the following groups. Control group (CT), wherein a rectangular skin section (2 x 8 cm) was dissected from the dorsal muscle layer, preserving the cranial vessels, lif...

AIM Ethylene vinyl alcohol copolymer (EVOH), its organic solvent dimethyl sulfoxide (DMSO), and N-Butyl 2-Cyanoacrylate (NBCA) are widely used in neurovascular embolization procedures and yet with potential risk of cytotoxicity. The aim of this study was to evaluate the toxic effect of EVOH-DMSO, its solvent DMSO and NBCA on cerebral parenchyma in a rabbit model. MATERIAL AND METHODS Forty-ei...
