A novel quantitative morphometry of germ cells for the histopathological evaluation of rat testicular toxicity. (1/423)

A view that 14 stages of rat spermatogenic cycle could be arranged into 4 groups, viz., conventional stages I-VI, VII-VIII, IX-XI and XII-XIV, according to the features of elongated spermatids was previously presented. A novel morphometry of seminiferous epithelia based on these 4 groups was also proposed. In the present study, utility of the proposed morphometry in the histopathological evaluations of testicular toxicities was monitored in comparison with the conventional one. After administrating adriamycin, ethylene glycol monomethyl ether or 1,3-dinitrobenzene to rats, the viability of their germ cells was estimated by the proposed morphometry and the conventional one employed stages II-III, V, VII, X and XII. In every case, the evaluating results of the proposed morphometry were similar to those of the conventional one. Thus, it was verified that the proposed morphometry was identical with the conventional one in respect of reliable detection of the testicular toxicities. In addition, in situ terminal dUTP nick end labeling indicated that death of spermatogonia, pachytene spermatocytes or round spermatids induced by the above 3 toxic compounds was exclusively apoptotic death. In conclusion, the proposed morphometry would be useful as a practical tool in the evaluation of testicular toxicities.  (+info)

Adaptation of bulk constitutive equations to insoluble monolayer collapse at the air-water interface. (2/423)

A constitutive equation based on stress-strain models of bulk solids was adapted to relate the surface pressure, compression rate, and temperature of an insoluble monolayer of monodendrons during collapse at the air-water interface. A power law relation between compression rate and surface pressure and an Arrhenius temperature dependence of the steady-state creep rate were observed in data from compression rate and creep experiments in the collapse region. These relations were combined into a single constitutive equation to calculate the temperature dependence of the collapse pressure with a maximum error of 5 percent for temperatures ranging from 10 degrees to 25 degrees C.  (+info)

Disseminated thrombosis and bone infarction in female rats following inhalation exposure to 2-butoxyethanol. (3/423)

Groups of 10 male and 10 female F344/N rats were exposed to 0, 31, 62.5, 125, 250, and 500 ppm of 2-butoxyethanol (BE) by inhalation, 6 hr/day, 5 days/wk, for 13 wk. Four moribund female rats from the 500 ppm group were sacrificed during the first 4 days of exposure, and 1 moribund female from the same group was sacrificed during week 5. Dark irregular mottling and/or loss of the distal tail were noted in sacrificed moribund rats. Similar gross lesions were noted in the terminally sacrificed females exposed to 500 ppm BE. Histologic changes noted in the day 4 sacrificed moribund rats included disseminated thrombosis involving the coccygeal vertebrae, cardiac atrium, lungs, liver, pulp of the incisor teeth, and the submucosa of the anterior section of the nasal cavity. Alterations noted in coccygeal vertebrae from the 500 ppm sacrificed moribund rats included ischemic necrosis and/or degeneration of bone marrow cells, bone-lining cells, osteocytes (within cortical and trabecular bone), and chondrocytes (both articular and growth plate), changes that are consistent with an infarction process. The moribund female rat that was sacrificed during week 5 and those female rats treated with 500 ppm and sacrificed following 13 wk of treatment lacked thrombi, but they had coccygeal vertebral changes consistent with prior infarction and transient or complete bone growth arrest. No bone lesions or thrombi were noted in the male rats treated with the same doses of BE. In conclusion, exposure to 500 ppm BE vapors caused acute disseminated thrombosis and bone infarction in female rats. Possible pathogenic mechanisms are discussed.  (+info)

Evaluation of exposure to ethylene glycol monoethyl ether acetates and their possible haematological effects on shipyard painters. (4/423)

OBJECTIVES: To evaluate exposure to mixed solvents containing ethylene glycol monoethyl ether acetate (EGEEA) in shipyard painters, to determine if EGEEA is toxic to the bone marrow. METHODS: An industrial hygiene survey was performed to identify exposure to EGEEA of two groups of shipyard painters, a low exposure group (n = 30) and a high exposure group (n = 27). Urinary ethoxyacetic acid and methyl hippuric acid as well as haemoglobin, packed cell volume, red cell indices, total and differential white blood cell counts (WBCs), and platelet count for the shipyard painters and the control subjects were measured. RESULTS: The mean (range) exposure concentration (ppm) to EGEEA in the high and low exposure groups were 3.03 (not detectable to 18.27), 1.76 (not detectable to 8.12), respectively. The concentrations of methyl hippuric acid and ethoxyacetic acid in the high exposure group were significantly higher than those in the control group. The mean WBCs in the high exposure group were significantly lower than in the control group, and a significant proportion, six (11%) of the 57 painters, were leucopenic; none of the controls were affected. CONCLUSION: The high rate of possible haematological effects among shipyard painters and a hygienic evaluation of their working environment in the present study suggests that EGEEA might be toxic to bone marrow.  (+info)

Efficient solubilization and purification of the gastric H+, K+-ATPase for functional and structural studies. (5/423)

When gastric H(+),K(+)-ATPase-containing microsomes are solubilized by detergents, a rapid loss of ATPase activity is generally observed. In this article, SDS/PAGE of octa(ethylene glycol)dodecyl monoether (C(12)E(8))- and n-dodecyl beta-d-maltoside-solubilized microsomes and their purifications by affinity chromatography on Reactive Red column reveal that inactivation is due to two main effects. (i) Solubilization activates an aspartic protease that cleaves down the alpha-subunit of the H(+),K(+)-ATPase. Addition of pepstatin A at slightly acidic pH and at low temperature prevents the proteolysis. (ii) A too-harsh delipidation inactivates the ATPase. When n-dodecyl-beta-d-maltoside is the detergent, the soluble H(+), K(+)-ATPase is highly active (2.5 micromol/mg per h at pH 6.0 and 5 degrees C) as long as ATP is added. When C(12)E(8) is used, the detergent induces an inactivation due to delipidation, since addition of lipids restores activity. The two subunits of the H(+), K(+)-ATPase are present in equimolar ratio in the n-dodecyl beta-d-maltoside-purified complex. Moreover, two main types of complex (330 and 660 kDa) were resolved in non-denaturing gels and should be the dimeric (alphabeta)(2) and tetrameric (alphabeta)(4) heterodimers respectively. In conclusion, purification of active, stable, soluble complexes of H(+),K(+)-ATPase with few lipids (a lipid/protein ratio of 0.25, w/w) has been achieved. This material should be useful for further structural studies.  (+info)

Determination of gamma-hydroxybutyrate (GHB) in biological specimens by gas chromatography--mass spectrometry. (6/423)

A simple liquid-liquid extraction procedure for the analysis of gamma-hydroxybutyrate (GHB) in biological fluids without conversion to its lactone, gamma-butyrolactone, is described. Following derivatization to its di-TMS derivative, GHB was detected using gas chromatography-electron impact mass spectrometry. Diethylene glycol was used as the internal standard. The limit of quantitation in 1 mL of blood was 1 mg/L, and a linear response was observed over the concentration range 1 to 100 mg/L. Coefficients of variation for both intra-assay precision and interassay reproducibility ranged between 3.9 and 12.0%. GHB was detected in the blood of a sexual assault victim (3.2 mg/L), in the blood of two driving (DUI) cases (33 and 34 mg/L), and in the blood and urine of two nonfatal GHB-overdose cases (blood 130 and 221 mg/L; urine 1.6 and 2.2 g/L). The observed clinical symptoms ranged from confusion, disorientation, vomiting, and nystagmus to ataxia, sinus bradycardia, unconsciousness, and apnea.  (+info)

Correlation between urinary 2-methoxy acetic acid and exposure of 2-methoxy ethanol. (7/423)

OBJECTIVES: To examine the correlation between airborne 2-methoxy ethanol (ME) exposures and the urinary 2-methoxy acetic acid (MAA) and to recommend a biological exposure index (BEI) for ME. METHODS: 8 Hour time weighted average (TWA) personal breathing zone samples and urine samples before and after the shift were collected from Monday to Saturday for 27 workers exposed to ME and on Friday for 30 control workers. RESULTS: No correlation was found between airborne exposure to ME and urinary MAA for nine special operation workers due to the use of personal protective equipment. For 18 regular operation workers, a significant correlation (r = 0.702, p = 0.001) was found between urinary MAA (mg/g creatinine) on Friday at the end of the shift and the weekly mean exposures of ME in a 5 day working week. The proposed BEI, which corresponds to exposure for 5 days and 8 hours a day to 5 ppm, extrapolated from the regression equation is 40 mg MAA/g creatinine. A significant correlation was also found between the weekly increase of urinary MAA (Friday after the shift minus Monday before the shift) and the weekly mean exposures of ME (r = 0.741). The recommended value of the weekly increase of urinary MAA for 5 days repeated exposures of 5 ppm ME is 20 mg/g creatinine. No urinary MAA was detected in workers in the non-exposed control group. CONCLUSIONS: The Friday urinary MAA after the shift or the weekly increase of urinary MAA is a specific and a good biomarker of weekly exposure to ME.  (+info)

Haematological and spermatotoxic effects of ethylene glycol monomethyl ether in copper clad laminate factories. (8/423)

OBJECTIVES: To investigate the effects of ethylene glycol monomethyl ether (EGME) on haematology and reproduction in exposed workers. METHODS: 53 Impregnation workers from two factories that make copper clad laminate with EGME as a solvent were recruited as the exposed group. Another group of 121 lamination workers with indirect exposure to EGME was recruited as the control group. Environmental monitoring of concentrations of EGME in air and biological monitoring of urinary methoxyacetic acid (MAA) concentrations were performed. Venous blood was collected for routine and biochemical analyses. Semen was collected from 14 workers exposed to EGME for sperm analysis and was compared with 13 control workers. RESULTS: Results of haematological examination showed that the haemoglobin, packed cell volume, and red blood cell count in the male workers exposed to EGME were significantly lower than in the controls. The frequency of anaemia in the exposed group (26.1%) was significantly higher than in the control group (3.2%). However, no differences were found between the female workers exposed and not exposed to EGME. After adjustment for sex, body mass index, and duration of employment, red blood cell count was significantly negatively associated with air concentrations of EGME, and haemoglobin, packed cell volume, and red blood cell count were significantly negatively associated with urinary concentrations of MAA. The pH of semen in the exposed workers was significantly lower than in the control workers, but there were no significant differences in the sperm count or sperm morphology between the exposed and control groups. CONCLUSION: It can be concluded that EGME is a haematological toxin, which leads to anaemia in the exposed workers. However, the data from this study did not support the theory of a spermatotoxic effect of EGME.  (+info)

N2 - Ethylene glycol monoethyl ether (EGEE) can cause damage to testes and sperm, and its metabolites are believed to play an important role in its toxicity. Aldehyde dehydrogenase 2 (ALDH2) is involved in the metabolism of this chemical. To investigate whether and how the enzyme affects the toxicity of EGEE, we conducted experiments comparing Aldh2 knockout mice with wild-type mice. Administration of EGEE at 100 and 600 mg/kg/day for one week did not induce any significant change in the weight and body weight ratios of testes, prostate and epididymides in either Aldh2 knockout or wild-type mice. However, motion of sperm from the spermaduct, as analyzed with a Hamilton-Thorne Sperm analyzer, was slightly decreased in ...

Scope. This standard specifies a method for the determination of fuel system icing inhibitor (FSII) content of aviation turbine kerosine within the range 0 % (V/V) to 0,2 % (V/V) FSII by high performance liquid chromatography (HPLC). This standard covers the determination of ethylene glycol monomethyl ether (EGME), which has previously been used in aviation turbine kerosine (AVTUR), and diethylene glycol monomethyl ether (AL41), which is now used in both aviation turbine kerosine for aircraft carriers (AVCAT) and AVTUR.. ...
Fuel system icing inhibitor (FSII) is an additive to aviation fuels that prevents the formation of ice in fuel lines. FSII is sometimes referred to by the registered, genericized trademark Prist. Jet fuel can contain a small amount of dissolved water that does not appear in droplet form. As an aircraft gains altitude, the temperature drops and Jet fuels capacity to hold water is diminished. Dissolved water can separate out and could become a serious problem if it freezes in fuel lines or filters, blocking the flow of fuel and shutting down an engine. Chemically, FSII is an almost pure (99.9%) ethylene glycol monomethyl ether (EGMME, 2-methoxy ethanol, APISOLVE 76, CAS number 109-86-4); or since 1994, diethylene glycol monomethyl ether (DEGMME, 2-(2-methoxy ethoxy) ethanol, APITOL 120, methyl carbitol, CAS number 111-77-3). Prior to 1994, Prist was regulated under the MIL-I-27686E standard, which specified use of EGMME, but subsequently came under the MIL-DTL-85470B, with use of less hazardous ...

Values obtained for specific surface area depend on the method of measurement. In adsorption based methods, the size of the adsorbate molecule (the probe molecule), the exposed crystallographic planes at the surface and measurement temperature all affect the obtained specific surface area.[4] For this reason, in addition to the most commonly used Brunauer-Emmett-Teller (N2-BET) adsorption method, several techniques have been developed to measure the specific surface area of particulate materials at ambient temperatures and at controllable scales, including methylene blue (MB) staining, ethylene glycol monoethyl ether (EGME) adsorption,[5] electrokinetic analysis of complex-ion adsorption[4] and a Protein Retention (PR) method.[6]. ...

Also some may have heard about the Mommys Bliss Nipple Cream and its safety in regard to infants. Again, I did research and though the FDA gave a warning as to the potential of harm, there were no actual reports of injury or illness caused by this product containg Chlorphenesin (click for documentation) and phenoxyethanol, the two suspected preservative ingredients. Why the FDA came out of nowhere on this warning is perplexing to the say the least. However, my conclusion is the chlorphenesin posed the major health risk more so than phenoxyethanol based on the information I located, especially since phenoxyethanol given in oral doses of the percentages used in cosmetics posed no health risk. First off chlorphenesin is not commercially available in the United States and it clearly states in the warnings; it is not approved for use in small children. And all the side effects listed are in the FDA warning as well. However, I personally dont eat my cosmetics, do you? How it ended up as a preserving ...
The category of Rosin Esters consists of rosin which has been esterified with alcohols, typically methanol, ethylene glycol, diethylene glycol, triethylene glycol, glycerol and pentaerythritol. Resin acids are the predominant components of rosin (,85%). Resin acids are composed of three skeletal classes of tricyclic carboxylic acids which share similar structure, but vary in the position of the double bonds and methyl groups. Hydrogenated rosin is implicitly included in the definition of rosin as disproportionated rosin which is a combination of hydrogenated and dehydrogenated rosin naturally produced when rosin is heated. The category therefore also includes the hydrogenated rosin forms of these substances. Due to the reactivity of resin acids, dimers can be formed. These rosin dimers are also known as oligomers or by the trivial name of polymerised rosin. As each member of this category is a UVCB, the resin acid components will vary in type and proportion. The number of ester bonds that can be ...

Aqueous amine solutions are the most used solvents for chemical absorption of CO2. Substituting part of the water by organic solvents in aqueous amine solutions aims to take advantage of the lower partial pressure and higher CO2 solubility. In this work, the influence of four organic solvents on solution density, viscosity, N2O solubility and absorption kinetics are studied. The organic solvents, Monoethylene Glycol (MEG), Diethylene Glycol (DEG), Triethylene Glycol (TEG) and CARBITOL, are blended with two amine solutions: MEA and DEEA-MAPA blend. The results show that the addition of organic solvents increases the density and viscosity. Furthermore, the N2O solubility, used to estimate the physical solubility of CO2 into a reactive system, increases when part of the water is substituted with an organic solvent. The kinetic experiments with a double stirred cell showed that in case of aqueous 5 M MEA, the substitution of part of the water increases both the mass transfer and kinetic coefficients ...

Moreover, the coexistence of different resistive find protocol switching behaviors has been found in many materials such as BiFeO3[11, 12], HfO2[13, 14], SrTiO3[15], ZnO [16-18], diamond-like carbon [19], and TiO2[20]. The choice of switching modes can broaden device applications and enable large flexibility in terms of memory architecture [15]. Generally, URS was preferred under high compliance current (CC), while BRS under low CC. In this letter, we present. an abnormal coexistence of URS with a low CC and BRS under high CC in the same Al/NiO/ITO device. Meanwhile, TRS was also observed by reducing the switching CC to forming CC. The Joule heating filament mechanism in a dual-oxygen reservoir structure composed of Al/NiO layer, and the ITO substrate. was responsible for the abnormal resistance switching. Methods NiO thin films were fabricated on ITO substrates by sol-gel process [21]. Nickel acetate tetrahydrate was used as a metal source, and 2-methoxyethanol and Fludarabine in vivo ...
Within a fortnight in November 2008, 34 Nigerian children, aged 4 months to 3 years, died and more than 50 others were hospitalised with severe kidney damage after taking the drug My Pikin (my child in local pidgin), a teething mixture containing paracetamol.1 The outbreak was due to the use of diethylene glycol (DEG)2 as a solvent for the paracetamol. DEG was present because of inadvertent or deliberate substitution of propylene glycol, which is much less toxic than DEG and is widely used in the pharmaceutical industry.3 DEG is a colourless and odourless liquid, commonly used in industry, and can be found in commercial products such as resins, antifreeze, inks and glues.4 It is a well-known human toxicant that causes generalised multi-organ failure characterised by acute renal failure (oliguria or anuria) frequently accompanied by severe neurological dysfunction (cranial nerve palsies, acute … ...

Symptoms of mild cinchonism (which may occur from standard therapeutic doses of quinine) include flushed and sweaty skin, ringing of the ears (tinnitus), blurred vision, impaired hearing, confusion, reversible high-frequency hearing loss, headache, abdominal pain, rashes, drug-induced lichenoid reaction (lichenoid photosensitivity),[1] vertigo, dizziness, dysphoria, nausea, vomiting and diarrhea. Large doses of quinine may lead to severe (but reversible) symptoms of cinchonism: skin rashes, deafness, somnolence, diminished visual acuity or blindness, anaphylactic shock, and disturbances in heart rhythm or conduction, and death from cardiotoxicity (damage to the heart). Quinine may also trigger a rare form of hypersensitivity reaction in malaria patients, termed blackwater fever, that results in massive hemolysis, hemoglobinemia, hemoglobinuria, and kidney failure.[citation needed] Most symptoms of cinchonism (except in severe cases) are reversible and disappear once quinine is withdrawn. ...
