Exposure to trichloroethylene II. Metabolites in blood and urine. (1/52)

Fifteen men were exposed to trichloroethylene (TRI) in three different ways with regard to the concentration of TRI in the air as well as exercise on a bicycle ergometer. The total amount of TRI supplied and taken up by each person was measured. The concentrations of trichloroethanol (TCE) and trichloroacetic acid (TCA) were determined in blood and urine. In spite of large differences in uptake, there were only small differences in the concentration of TCA in blood during the day of exposure. There was a large scatter for the values of TCA in urine within each group. The concentration of TCE in arterial blood increased during exposure. Thereafter the concentrations were almost constant for 2 h and differed among the groups. These results can be interpreted as being due to balanced rates of the formation and elimination of TCE. The levels mentioned were related to the uptake of TRI. The same was found for the rate of excretion of TCE in urine when calculations were made from the morning sample obtained the day after exposure.  (+info)

Mutagenicity of chloroacetaldehyde, a possible metabolic product of 1,2-dichloroethane (ethylene dichloride), chloroethanol (ethylene chlorohydrin), vinyl chloride, and cyclophosphamide. (2/52)

We have previously described a very sensitive and efficient bacterial test designed to detect chemical carcinogens as mutagens. Chloroacetaldehyde is mutagenic in this system and is of interest because it is a possible metabolite in mammals of the large volume industrial chemicals 1,2-dichloroethane (ethylene dichloride) (3.5 billion kg/yr, U.S.) and vinyl chloride (2.5 billion kg/yr, U.S.), and of the antineoplastic agent cyclophosphamide. Chloroacetaldehyde reverts a new Salmonella bacterial tester strain (TA100). Chloroacetaldehyde is shown to be hundreds of times more effective in reversion of TA100 than is chloroethanol (ethylene chlorohydrin), a known metabolic precursor of chloroacetaldehyde and a possible metabolite of dichloroethane and vinyl chloride, or than vinyl chloride, which is itself mutagenic for TA100. Chloroethanol is shown to be activated by rat (or human) liver homogenates to a more highly mutagenic form with reversion properties similar to chloroacetaldehyde. Reversion properties of cyclophosphamide after in vitro metabolic activation suggest that chloroacetaldehyde is not the active mutagenic form of this antineoplastic drug.  (+info)

Isolation and characterization of 2,3-dichloro-1-propanol-degrading rhizobia. (3/52)

2,3-Dichloro-1-propanol is more chemically stable than its isomer, 1, 3-dichloro-2-propanol, and is therefore more difficult to degrade. The isolation of bacteria capable of complete mineralization of 2, 3-dichloro-1-propanol was successful only from enrichments at high pH. The bacteria thus isolated were found to be members of the alpha division of the Proteobacteria in the Rhizobium subdivision, most likely Agrobacterium sp. They could utilize both dihaloalcohol substrates and 2-chloropropionic acid. The growth of these strains in the presence of 2,3-dichloro-1-propanol was strongly affected by the pH and buffer strength of the medium. Under certain conditions, a ladder of four active dehalogenase bands could be visualized from this strain in activity gels. The enzyme involved in the complete mineralization of 2,3-dichloro-1-propanol was shown to have a native molecular weight of 114,000 and consisted of four subunits of similar molecular weights.  (+info)

The entry of alpha-chlorohydrin into body fluids of male rats and its effect upon the incorporation of glycerol into lipids. (4/52)

The rate of entry of alpha-chlorohydrin into rat rete testis fluid has been studied using the 14-C and 36-Cl-labelled compounds. The alpha-chlorohydrin crosses the blood-testis barrier and the concentration of radioactivity in rete testis fluid attained blood levels within 45 min. Within 3 hr of a single injection of [14-C] alpha-chlorohydrin, radioactivity was widely distributed in body fluids, and was present in the lipids of the brain, testis, epididymis and epididymal fat pads. No radioactivity was found in tissue lipids following the administration of [36-Cl] alpha-chlorohydrin, which suggests that dechlorination of this compound occurs before its incorporation. Neither a single high dose nor repeated low doses of alpha-chlorohydrin induced changes in the incorporation of [14-C] glycerol into lipids of the brain, testis, epididymis and epididymal fat pads.  (+info)

Purification and structure of the major product obtained by reaction of NADPH and NMNH with the myeloperoxidase/hydrogen peroxide/chloride system. (5/52)

The first spectrophotometric study of the reaction of the myeloperoxidase/H2O2/Cl- system with NADPH and NMNH showed that the reaction products were not the corresponding oxidized nucleotides and that modifications would take place on the nicotinamide part of the molecule [Auchere, F. & Capeillere-Blandin, C. (1999) Biochem. J. 343, 603-613]. In this report, in order to obtain more precise information on the structural modifications and mechanism of the reaction, we focus on the purification and isolation of products derived from NADPH and NMNH by RP-HPLC. Electrospray ionization mass spectra indicated that the relative height of the peaks reflected that of the natural isotopic abundance of 35Cl and 37Cl, providing evidence that the products derived from NADPH and NMNH were monochlorinated. Moreover, calculated masses revealed the 1 : 1 addition of HOCl to the molecule. Various 1D and 2D NMR experiments provided data for the assignments of the chemical shifts of protons and carbons and the coupling constants of the protons of the chlorinated nucleotides. Further NOESY experiments allowed the characterization of the spatial structure of the chlorinated product and showed that trans HOCl addition occurred at the C5=C6 carbon double bond of the nicotinamide ring, leading to a chlorohydrin.  (+info)

Mutagenic potential of bisphenol A diglycidyl ether (BADGE) and its hydrolysis-derived products in the Ames Salmonella assay. (6/52)

The mutagenicity of bisphenol A diglycidyl ether (BADGE), its first and second hydrolysis products (the diol epoxide and bis-diol of BADGE, respectively) and the bis-chlorohydrin of BADGE were investigated using the Ames Salmonella assay with strains TA98, TA100, TA1535 and TA1537. The assays were performed in the absence and presence of various concentrations of rat liver S9 fraction. The results obtained confirm the mutagenic power of BADGE in strains TA100 and TA1535 and show a positive response to the diol epoxide of BADGE in these strains, although the latter compound was approximately 10 times less potent than the former. A lack of mutagenic activity of the bis-diol of BADGE and the chlorohydrin under study is also shown. These findings suggest that BADGE and, to a much lesser extent, the diol epoxide of BADGE may constitute a genotoxic hazard, but not the bis-diol or bis-chlorohydrin of BADGE.  (+info)

Lipid analysis of human HDL and LDL by MALDI-TOF mass spectrometry and (31)P-NMR. (7/52)

The analysis of HDL and LDL is important for the further understanding of atherosclerosis because changes of the protein and lipid moieties occur under pathological conditions. Because destruction of lipids leads to the formation of well-defined products such as lysophospholipids or chlorohydrins, methods that allow their fast and reliable determination would be useful. In this study, matrix-assisted laser desorption and ionization time-of-flight mass spectrometry (MALDI-TOF MS) was applied for the analysis of the lipid composition of human lipoproteins. These data were compared with high resolution (31)P-NMR spectroscopy. Differences between LDL and HDL in sphingomyelin and phosphatidylcholine content could be monitored by NMR and mass spectrometry, and differences with respect to the extraction efficiency were found by MALDI-TOF MS. Additionally, treatment of LDL with hypochlorite and phospholipase A(2) resulted in marked changes (formation of chlorohydrines and lysolipids). Lysophosphatidylcholines were detectable by both methods, whereas MALDI-TOF MS failed to detect chlorohydrines of phospholipids. We conclude that MALDI-TOF MS provides rapidly a reliable lipid profile of lipoproteins. However, a previous lipid separation must be performed to detect lipid oxidation products. NMR can be directly applied, but suffers from lower sensitivity, and provides only limited information on fatty acid composition.  (+info)

The effects of alpha-chlorohydrin on the composition of rat and rabbit epididymal plasma: a possible explanation of species difference. (8/52)

The relationship between the antifertility effect of alpha-chlorohydrin and changes in composition of luminal plasma from the cauda epididymidis of rats and rabbits has been investigated. At each dose regimen studied, the fertilizing capacity of rats treated with alpha-chlorohydrin was reduced to zero. The levels of sodium, potassium, glycerylphosphorylcholine (GPC), acid phosphatase and alkaline phosphatase in epididymal plasma were not markedly affected by drug treatment. The most noticeable change was a considerable increase in the concentration of lactic dehydrogenase (LDH) at all dose levels and of glutamic-oxaloacetic transaminase (GOT) after 7 days of treatment with 8 and 16 mg/kg. The effect of cold shock on the composition of epididymal plasma showed that LDH and GOT are, at least in part, derived from spermatozoa. In contrast, alpha-chlorohydrin did not have an antifertility action in the rabbit, and the only notable change in the compositon of epididymal plasma was an increase in the level of GPC. These results provide evidence that, in the rat, alpha-chlorohydrin or a metabolite primarily exerts its antifertility effect by a direct action on the spermatozoa, whilst in the rabbit a barrier may exist to the entrance of the drug into the lumen of the epididymal duct.  (+info)

The oxidation of low-density lipoprotein (LDL) is thought to contribute to atherogenesis, which is an inflammatory disease involving activation of phagocytic cells. Myeloperoxidase, an enzyme which is able to produce hypochlorous acid (HOCl), is released from these phagocytic cells, and has been found in an active form in atherosclerotic plaques. HOCl can oxidize both the lipid and protein moiety of LDL, and HOCl-modified LDL has been found to be pro-inflammatory, although it is not known which component is responsible for this effect. As HOCl can oxidize lipids to give chlorohydrins, we hypothesized that phospholipid chlorohydrins might have toxic and pro-inflammatory effects. We have formed chlorohydrins from fatty acids (oleic, linoleic and arachidonic acids) and from phospholipids (stearoyl-oleoyl phosphatidylcholine, stearoyl-linoleoyl phosphatidylcholine and stearoyl-arachidonoyl phosphatidylcholine), and investigated various biological effects of these oxidation products. Fatty acid and ...

The major part of this thesis describes the asymmetric synthesis of β- and γ-amino alcohols through the combination of ruthenium catalyzed racemization and enzymatic kinetic resolution.. The dynamic kinetic resolution, DKR, protocol for chlorohydrins was improved by employing Bäckvalls catalyst, which is a base activated racemization catalyst, in combination with Burkholderia cepacia lipase. These optimized conditions broadened the substrate scope and improved the yields and ees of the obtained chlorohydrin acetates. The utility of the method was demonstrated in the synthesis of (S)-salbutamol.. In the second part of the thesis, DKR was utilized in the enantio-determining step of the total synthesis of (R)-duloxetine. Optimized DKR conditions, combining Bäckvalls catalyst together with Candida antarctica lipase B, afforded a β-cyano acetate in high yield and ee. (R)-Duloxetine was accessible through synthetic alterations of the enantioenriched β-cyano acetate in high overall ...

When water attacks carbon, carbon lets go of the electrons binding it to bromine. (bromine wanted them anyway) thus breaking the bromonium bridge.. The attacking oxygen atom still has 2 bound hydrogen atoms for a total of 3 bonds and one lone pair. This results in an oxonium, or an oxygen atom with a positive formal charge.. Oxygen, an electronegative atom, is not thrilled with the positive charge and therefore pulls on the electrons binding it to hydrogen. This results in a slightly less positive oxygen, and a partially positive hydrogen atom.. Another water molecule in solution reaches out with one of its nucleophilic lone pairs to grab the partially positive hydrogen atom. The electrons break away and return to the oxygen giving it a second lone pair and neutral charge.. This resulting product is a halohydrin. If bromine you get a bromohydrin, if chlorine youll get a chlorohydrin.. How Markovnikovs Rule Factors In:. Recognize that at no point in this explanation did I mention a carbocation. ...

NIOSH considers the evidence of carcinogenicity of ethylene dichloride reported by the National Cancer Institute to be conclusive in two mammalian species (the rat and the mouse). Since ethylene dichloride causes progressive, malignant disease of various organs in two species of animals, NIOSH recommends that ethylene dichloride be considered carcinogenic in man. Therefore, because it is not presently possible to establish an exposure level at which ethylene dichloride may be regarded to be without risk, NIOSH recommends that exposure to ethylene dichloride be kept as low as feasible. The use of ethylene dichloride as a solvent, diluent, or fumigant in open operations should be prohibited. Product substitution should be a paramount consideration, and wherever ethylene dichloride is identified or its presence suspected, it should be replaced by a less harmful substitute. - NIOSHTIC-2 NIOSHTIC no. 20000298 ...

A comprehensive disposition and metabolism study of epichlorohydrin (ECH) has not been previously reported. In this study, male Fischer 344 rats were dosed (6 mg/kg) orally with [2-14C]ECH (98% radiochemically pure) as an aqueous solution and killed after 3 days. Approximately 38% of the radioactive dose was exhaled as CO2, 50% was excreted as metabolites in the urine, and 3% was present in the feces. Radioactivity in tissues accounted for the remainder of the administered dose. When expressed per gram of tissue, radioactivity was highest in liver, kidney, and forestomach. The half-life of initial elimination of radioactivity in both the urine and exhaled air was about 2 hr, indicating that ECH was rapidly absorbed and metabolized. The major metabolites in the urine were identified as N-acetyl-S-(3-chloro-2-hydroxypropyl)-L-cysteine and alpha-chlorohydrin, about 36 and 4% of the administered dose, respectively. Finding these metabolites, which have not been previously reported, is consistent ...

With the purpose of improving the mechanical properties of the polyamides, the possibility of combining polyamides with elastomers has been used. The low compatibility of the resulting blends leads to deficient mechanical properties, and therefore, it is necessary to add the compatibilizer to the mixture or to produce the compatibilizer during the melting mixture. Usually, at least one of the components must contain a reactive functional groups. In the present work, blends of polyamide 6 (PA 6) and epichlorohydrin elastomers, polyepichlorohydrin (PEPI), and the equimolar copolymer poly(epichlorohydrin-co-ethylene oxide), EGO, with different compositions were prepared by mechanical mixture using a Banbury-type mixer. The blends were characterized by rheological measurements, the Molau test, elemental analysis, Infrared Spectroscopy by Diffuse Reflectance, Transmission Electron Microscopy, and X-ray Diffractometry. The blends of PA 6 with PEPI and ECO are heterogeneous, showing a morphology of ...
Like most things in Scouting, the BSA numbering system came about to fill a need. The need was to be able to chart a Scouts progress without having to write out the full names of merit badges in very small spaces. The first fourteen merit badges, numerically speaking, were the Eagle required merit badges at the time the numbering system originated. The Safety and Sports merit badges are no longer Eagle required while Family Life, Cycling, and Hiking have been added. The remainder of the badges are basically in alphabetical order with newer badges added at the end. This list also includes discontinued merit badges which were part of the numbering system. These merit badges are provided for reference purposes only. Current merit badges are linked to their requirements pages, discontinued merit badges are not linked. ...

Even if you do not have any of the above, you can still apply if you have a substantial disability likely to last longer than 12 months - you can get evidence of this from your GP, nurse of consultant however if you do use this option it is likely that your local authority will send you to one of their doctors for a quick assessment. I have not been on this sort of assessment so can not tell you what it is or how it goes - if anyone reading this has, please let us know via the comments box below. Once you have the blue badge it will help with the tiredness as you'll be able to park on single or double yellow lines (for no longer than 3 hours) or within disabled bags; which are always closer - rather than having to find a car parking space and walking.. The badge also allows you to forgo some road fees e.g. The Second Seventh Bridge toll or the London Conjestion Charge (however you do have to apply for this one) - there might be others near you.
