Chemical exposure to the eye may result in a chemical burn to the eye. Damage is usually limited to the front segment of the eye, including the cornea, the conjunctiva and occasionally the internal eye structures of the eye, including the lens. Burns that penetrate deeper into the anterior chamber are the most severe, often causing cataracts.. Note: The RMA SOP factor is limited to chemical burns where the chemical penetrates into the anterior chamber.. Chemical burns to the eye can be divided into three categories: alkali burns, acid burns, and irritants.. Alkali burns are the most dangerous. Alkalis (chemicals that have a high pH level) penetrate the surface of the eye and can cause severe injury to both the external structures like the cornea and the internal structures like the lens.. Common alkali substances contain the hydroxides of ammonia, lye, potassium hydroxide, magnesium, and lime. Substances that may contain these chemicals include fertilizers, cleaning products (ammonia), drain ...

A variety of plant diseases and damage by certain pests in agricultural and horticultural plants can be efficiently controlled without substantial chemical injuries by applying a plant-protecting composition which comprises (a) 1 part by weight of a chitosan hydrolyzate having an average molecular weight of 10,000 to 50,000, obtained by acid hydrolysis or enzymatic hydrolysis of chitosan and (b) 0.25 to 4 parts by weight of acetic acid. Any possible chemical injury to plants caused by applying the composition can be further reduced when the composition is admixed with a deproteinized juice of alfalfa leaves.
A limitation to the use of biologic therapies is the risk of significant systemic adverse events. Local administration achieves lower systemic exposure to the drug and therefore is likely associated with lower rates of severe adverse events. The use of infliximab eye drops has been investigated as an alternative modality for local drug delivery. The administration of topical infliximab eye drops reduced corneal opacity, perforation, and eyelid fibrosis in a mouse model of corneal alkali burn,19 and improved tear volume, corneal surface regularity, and goblet cell density in a mouse model of dry eye.20 In rabbit models, the use of topical infliximab prevented corneal neovascularization21 and suppressed subconjunctival wound healing after trabeculectomy.22 On the other hand, cerebrovascular accidents are recognized complications of systemic anti-VEGF therapy23 while anti-TNF-α agents are associated with a risk of opportunistic infections, malignancies, infusion reactions, as well as cardiac and ...

We put the Hartz flea collars on 6 days ago onto 3 cats…wish Id known sooner! All 3, none of them related in any way, have the burns. One is pretty mild, just a quarter sized spot of missing fur and slightly irritated skin, one is all the way around his neck in a perfect stripe with missing skin and medium irritation, and the other goes from ear to ear and has progressed to a "V" about 3 inches down his chest! They werent too tight, either. The cat that is affected the worst, we had to PEEL the collar off of him from the oozing and we did that at day 4, but the other 2 looked ok, so we figured just an allergy. The other 2 just have thicker fur and it took a little longer, I guess. I bought them at Walmart, still have the receipt, and they will be getting the collars back along with a pic of all 3 cats so they can see the damage a product that they sell does! Hartz will also be hearing from me, and I have heard there is a class-action lawsuit filed that I will be checking into! Absolutely ...

It normally begins with unfortunate propensities. Smoking, the absence of rest, anxiety and, in particular, the nourishments you eat can all influence your bodys pH levels.. At whatever point you eat food which leads to the acid formation in the stomach, for example, dairy, grains, meats and sugar, your body needs to utilize alkalizing minerals, for example, calcium, sodium, potassium, and magnesium to kill the corrosive delivered from metabolizing these sustenances.. When you dont eat enough soluble sustenances to recharge these, your body needs to utilize minerals from crucial organs and issues that remain to be worked out the corrosive in your body..

Spent caustic is a waste industrial caustic solution that has become exhausted and is no longer useful (or spent). Spent caustics are made of sodium hydroxide or potassium hydroxide, water, and contaminants. The contaminants have consumed the majority of the sodium (or potassium) hydroxide and thus the caustic liquor is spent, for example, in one common application H2S (gas) is scrubbed by the NaOH (aqueous) to form NaHS (aq) and H2O (l), thus consuming the caustic. Ethylene spent caustic comes from the caustic scrubbing of cracked gas from an ethylene cracker. This liquor is produced by a caustic scrubbing tower. Ethylene product gas is contaminated with H 2S(g) and CO2(g), and those contaminants are removed by absorption in the caustic scrubbing tower to produce NaHS(aq) and Na 2CO 3(aq). The sodium hydroxide is consumed and the resulting wastewater (ethylene spent caustic) is contaminated with the sulfides and carbonates and a small fraction of organic compounds. Refinery spent caustic comes ...
PURPOSE: The present study was conducted to investigate healing of alkali-burned corneas in MRL/MpJ (MRL) mice. METHODS: Gross, clinical, and histologic criteria were used to compare healing of alkali-burned corneas in MRL and control C57BL/6J (B6) mice. Effects of neutrophil depletion of B6 mice and allogeneic reconstitution of B6 mice with MRL bone marrow on wound healing were evaluated. Gene expression patterns in normal and wounded corneas were surveyed with array-based quantitative real-time RT-PCR (AQPCR). RESULTS: MRL mice showed accelerated reepithelialization and decreased corneal opacity compared with B6 mice after alkali wounding. Marked inflammatory cell infiltration and fibrosis were evident in the corneas and anterior chambers of B6 mice. MRL mice showed less severe lesions, except for stromal edema. Rapid reepithelialization and reduced keratitis/iritis were also observed in neutrophil-depleted B6 mice, but not in B6 mice reconstituted with MRL bone marrow. AQPCR showed

Abstract: : Purpose: To propose a model of late onset diffuse lamellar keratitis(DLK) that is observed after chemical or mechanical corneal injury in patients with previous laser in situ keratomileusis (LASIK). Methods: Corneal flaps were created in eight eyes from four White New Zealand Rabbits. The flaps were reflected and then repositioned and allowed to heal for two weeks. One eye of each rabbit was then given either a chemical (0.5N NaOH) or mechanical epithelial injury with the contralateral eye serving as control. Corneas were then harvested one day after the injury was created for microscopic analysis. Results: Histopathalogical analysis of sections from corneas that sustained mechanical injury show focal aggregates of heterophils, macrophages, and mild corneal edema at the flap-stromal interface. After chemical injury, in addition to heterophils and macrophages, focal and subepithelial aggregates of fibroblasts and myxomatous stromal changes were observed at the flap-stromal interface. ...
A chemical burn occurs when living tissue is exposed to a corrosive substance such as a strong acid or base. Chemical burns follow standard burn classification and may cause extensive tissue damage. The main types of irritant and/or corrosive products are: acids, bases, oxidizers / reducing agents, solvents, and alkylants. Additionally, chemical burns can be caused by some types of chemical weapons, e.g., vesicants such as mustard gas and Lewisite, or urticants such as phosgene oxime. Chemical burns may: need no source of heat, occur immediately on contact, not be immediately evident or noticeable, be extremely painful, diffuse into tissue and damage structures under skin without immediately apparent damage to skin surface. The exact symptoms of a chemical burn depend on the chemical involved. Symptoms include itching, bleaching or darkening of skin, burning sensations, trouble breathing, coughing blood and/or tissue necrosis. Common sources of chemical burns include sulfuric acid (H2SO4), ...

After noticing the nice caustic through a glass of cognac one late evening I decided to simulate it. Not having a 3d-model of a cognac glass (or a modeling package) I ended up writing a program that would take a number of sample points a generate a smooth spline curve, which was then used to generate a surface of revolution. This image was rendered on a P-90 in 4 hours using 64 samples per pixel, and something around 200.000 photons for the caustic. Notice the detail in the caustic as well as the smoothly connected caustic & shadow boundary. The high number of pixel-samples was necessary to reduce noise in the depth-of-field simulation. ...

Purpose : To investigate if topically applied mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs) promote corneal wound repair in a rat alkali burn model Methods : EVs were isolated from media conditioned by human bone marrow-derived MSCs (n=4) using a series of centrifugation, filtration and ultracentrifugation steps followed by transmission electron microscopy (TEM) and nanoparticle tracking analysis (NTA; NanoSight) quality control. Pro-healing effects of hMSC-derived EVs (hMSC-EV) were examined in vitro by cell migration and scratch wound healing assays using human corneal epithelial (HCE) and endothelial (HCEC) cell lines. Human cornea wound healing rate was also determined ex vivo using fluorescein penetration test. Rat corneal alkali burn injury was induced using 1M NaOH and injury was treated with or without 30mg of hMSC-EVs. Efficacy of treatment was monitored by biomicroscopy and optical coherence tomography (OCT) followed by extensive tissue analysis at the end of the ...

Consuming ashes is, at the least, extremely harmful to dogs. Most folks do not know that the old time way of acquiring lye for soap making is to leach water through hardwood ashes. The leachate is lye, a dangerously caustic substance, both internally and externally. However, even the ash of non-hardwoods when soaked with water will produce a severely caustic substance. If an unknown quantity of wet ashes and/or the soil underneath is ingested by a dog it causes acute alkalosis. In other words, the dogs ph drops too low, too fast for its body to recover and acts like a toxin, killing the dog within a couple days. The dog suffers miserably. We know ...

2003) The use of Ammonium Bifluoride (ABF) in place of Hydrofluoric Acid can be deceptively dangerous as, in H2O, the ABF will cleave a hydrogen fluoride molecule creating hydrofluoric acid. . . the concentration of HF acid will be proportionate to the amount of ABF in solution and the ratio (20/57) of molecular weights. This is not a safe solution as many have been burned, some seriously with ABF solutions.. I would be extremely cautious in using ammonium bifluoride as a substitute for HF since, upon solubilizing, it springs an HF molecule. The resulting HF concentration will be ~1/3 of the original Ammonium Bifluoride concentration.. Also, if using ammonium fluoride (AF) in an acid medium (i.e., HCl) the H+ ions will convert the fluoride to HF. This is common technology used in oil-well regeneration (in silica media)as AF and HCl are simultaneously pumped "down hole" with the evolution of HF in a safer (down hole) environment..

The effect of chemical cleaning on the nanofiltration of two pharmaceutically active compounds (PhACs),. namely sulfamethoxazole and carbamazepine, was investigated. Membrane cleaning was simulated by. exposing the virgin membrane samples to cleaning reagents including acidic, caustic, sodium dodecyl. sulphate (SDS), and ethylenediaminetetraacetic-acid (EDTA) under controlled conditions. Prolonged. exposure to acid and SDS rendered the membrane slightly less negatively charged. Caustic and acidic. cleaning, however, resulted in a marked increase in the membrane surface hydrophobicity. In addition,. it is hypothesised that chemical cleaning may alter the porosity of the polymeric matrix and even the. hydrophilicity within the membrane active layer. Indeed, caustic cleaning led to an increase in the membrane permeability while acidic cleaning produced the opposite effect. An increase in the membrane permeability was also observed as a result of SDS and EDTA cleaning. This hypothesis is also ...

ASTM C581 2 laminate testing is the standard by which suitability of various resins are judged. Bare glass weight loss (Figures 1 & 2) when exposed to a corrosive media is a good screening tool for determining suitability of glass fiber compositions 3. Stress corrosion testing (Figures 3 & 4) imposes another dimension to determining suitability of various types of glass fibers in a composite cross-section to different types of corrosive media while under stress. Details of this testing under a broad range of corrosive media and various loads can be found in several sources 4&5 but are similar in concept to ASTM D36816 All of these methods yield valuable quantitative data concerning the suitability of composite materials using various resins & glass ...

If there is a chemical injury, immediate irrigation with water is critical. Flush the eyes and face with any available source of water for at least 10-15 minutes. Follow up immediately with a trip to the emergency room or ophthalmologist.. If a sharp object has penetrated the eye (like a fish hook), do not pull it out, but transport the person to the emergency room as soon as possible. Other blunt or sharp injuries should be examined by an ophthalmologist, since the serious nature of the injury may not be readily apparent.. ...

Tomorrow is my day to re-order my supplies and I will be ordering a second soft serter. I couldnt be more please with the infusion sets and soft-serters. I was told that as a person with chemical injury I would never be able to use a pump..Well the wrong word was said to me..and that was never. I have been pumping now with both brands for a tad over 4 years. No eye complications or kidney complications as of yet. I do have optic neuritis but that is from something else not diabetes related.

For Petes sake, Ive seen toilets that get so explosive upon flushing that they look more like a geyser than a whirlpool - so its not always caused by a hover-peer.. (*checks to see if MOTW has been to his bathroom lately, where new toilet has been known to do its Old Faithful routine.*). Special Underpants would also be AGNFARB for Geriatrics &/or Toddlers.. Tell me, has anyone OTHER than a lawyer ever spoken like this?.

It all started one day at work while I was on a phone meeting. I started feeling some mild discomfort that grew until I was actually in a lot of pain with pressure (in the center of my lower chest, upper stomach area), could hardly breathe, and felt like I was both going to both pass out and throw up at the same time. I thought that I was having a heart attack. And all I could think was, just great. I finally decide to take control of my life and get healthy and its too late and Im going to die anyway. (I think that I had lost about 20 or so lbs at that stage). So, I went down to the security office at work, put my head down on the counter and said, "I think Im having a heart attack." They hustled me into the office and whipped out an oxygen mask, started taking vital statistics and called EMS. Of course, right around the time that EMS came, I started feeling better and of course then started feeling really embarrassed for causing such a fuss. EMS convinced me that I should run down to see ...
sewer processes refereed paper technical features 86 MARCH 2011 water Discussion From the trends illustrated in Figure 8, it is evident that the optimised Caustic Wash was able to maintain dramatically reduced H2S levels for a period well in excess of 20 days (at which point the LAP had to be shut down for other operational reasons). Unfortunately, since the LAP is critical operational infrastructure, we did not have the luxury to control its operation purely for the benefit of obtaining an ideal set of experimental results. Hence, the precise duration of these reduced H2S levels, under controlled conditions, is undetermined. The trend from Wash #3 (Figure 8) suggests that several months of good results may be achieved from an optimised Caustic Wash. It was found that after several washes, both the magnitude and duration of the H2S decrease significantly improved. After Wash#3, H2S levels remained quite low for a period in excess of in excess of 180 days, which is in support of Figure 8. At 180 ...
