What is acenaphthene used for

{ 02:37, 21/6/2012 } { 0 comments } { Link }
Many of the PAHs are used to conduct investigation. Like most PAHs, acenaphthene is utilised to produce dyes, plastics and pesticides. Acenaphthene continues to be located in cigarette smoke, inside the exhaust from vehicles as well as in wood preservatives. One of the most typical methods acenaphthene can enter your system is thru respiration contaminated air. It may go into your lungs when you breathe it. If you dwell in close proximity to or perform within a hazardous waste internet site in which PAHs are disposed, you might be probably to breathe acenaphthene as well as other PAHs. In case you consume or consume foods and drinking water that are contaminated with PAHs, you can be uncovered. Coverage can also occur if your skin arrives into contact with contaminated soil or items like weighty oils, coal tar, roofing tar or creosote in which PAHs happen to be identified. Creosote is definitely an oily liquid present in coal tar and is particularly utilised to maintain wooden. When inside you, the PAHs can unfold and target fat tissues. Goal organs consist of kidneys, liver and body fat. Yet, in just a make a difference of times, the PAHs will go away your body via urine and feces.

What exactly are the wellbeing consequences of publicity to acenaphthene

{ 03:36, 20/6/2012 } { 0 comments } { Link }
Quite a few PAHs have induced tumors in laboratory animals which were subjected to PAHs by way of their meals, from respiration contaminated air and when it was utilized to their skin. When pregnant mice ate higher doses of a PAH (benzo(a)pyrene) they knowledgeable reproductive troubles. What's more, the offspring in the pregnant mice showed birth defects along with a lessen inside their physique weight. Other outcomes incorporate damage to pores and skin, entire body fluids as well as the immune program which helps your body fight illness. Yet, these consequences are yet to been witnessed in human beings. Acenaphthene can trouble your skin and mucous membranes. Animal scientific studies showed that rats fed 2 grams of acenaphthene for 32 times (long-term) had changes inside their blood and a few harm to the liver, kidney and lungs. There may be no information offered from research on human beings to inform what effects can end result from currently being subjected to personal PAHs at specific levels. Nevertheless, respiration PAHs and skin contact appear to be related with cancer in human beings. Animal studies showed that mice subjected to 308 areas for every million (ppm) of PAHs (particularly benzo(a)pyrene) in food for ten times (short-term publicity) had offspring with birth defects. Mice subjected to 923 ppm of benzo(a)pyrene in food items for a time of months designed problems inside the liver and blood.

How could you be exposed to acenaphthene?

{ 03:49, 19/6/2012 } { 0 comments } { Link }
It is possible to be confronted with most PAHs within the environment, in your home as well as in the office. Because PAHs exist normally in the setting, and they are man-made, you can be exposed in a number of approaches. Acenaphthene has become detected in fumes from car exhaust, coal, coal tar, and at hazardous waste websites. They're all sources of exposure. Because acenaphthene has become found in cigarettes, it is possible to be uncovered by respiratory cigarette and tobacco smoke. Publicity to other PAHs can arise by ingesting food items grown in contaminated soil or by ingesting meat or other food items which you grilled. Grilling and charring food truly increases the sum of PAHs inside the food. Should you function in the plant which makes coal-tar or that makes use of petroleum or coal, or makes or makes use of wood preservatives, you may be confronted with acenaphthene along with other PAHs.

Time to peak of salicylic acid in the morning administration long, long half-life of the evening the opposite. Reasonable administration of the morning dosage slightly increased. Night plus service time.

Usage of some diseases and the best dosage:
Systemic arterial embolism occurred in brain heart disease prevention valve alone, aspirin is invalid, but in combination with dipyridamole, will enhance the effect of small doses of dipyridamole.
Avoid and glucocorticoids in combination; avoid coumarin anticoagulant drugs, lowering blood sugar drug methotrexate, barbiturates, aniline and other combination.
After meals. American College of Chest Physicians Antithrombotic and Thrombolytic Therapy Association (ACCP) evidence-based guidelines state that the use of aspirin to prevent myocardial infarction, stroke and vascular death, the patient should be based on condition, the optimal dose.
A large number of clinical trials have shown that the majority of patients, including patients with chronic stable or unstable angina, aspirin 75mg / day can effectively reduce the risk of acute myocardial infarction and death. This dose can be reduced transient cerebral ischemic attack in patients with stroke and death incidence. Europe a stroke prevention studies have shown that a history of transient ischemic attack and stroke in patients with a history of aspirin 25mg, 2 times a day, 50mg / day can reduce the risk of stroke or death. Clinical Practice has proved that even in patients taking higher aspirin doses than the table, will not effect a further increase in the occurrence of side effects is greatly increased. Therefore, in the treatment of various thrombotic diseases, patients should use the smallest effective dose, ie, long-term application of 50-160mg / day, in order to achieve maximum efficacy, minimize side effects, this is the patients taking aspirin the optimal dose.

Aspirin Drug Introduction

{ 03:53, 29/5/2012 } { 0 comments } { Link }
As early as 1853 Charles Gerhardt, salicylic acid and acetic anhydride synthesized acetylsalicylic acid, but no attention has been paid; 1898 German chemist Feihuofuman, synthetic, and for his father to treat rheumatism arthritis, excellent efficacy; 1899 by Theodore Dreiser introduced into clinical, and named aspirin. So far, aspirin has been applied a century, the medical history of the three classic one of the drugs, it still is the world's most widely used antipyretic, analgesic and anti-inflammatory drugs, but also as a comparison and evaluation of other drugs Standard preparations. Antithrombotic effect in vivo, can inhibit the platelet release reaction, inhibition of platelet aggregation, reduction of TXA2 generated. Clinically used to prevent the onset of cardiovascular and cerebrovascular diseases. Aspirin in the 1898 listing, in recent years it also has the role of anti-platelet aggregation, and so re-aroused great interest. Aspirin and other salicylic acid derivatives and polyvinyl alcohol, cellulose acetate, etc. Containing Hydroxyl polymer melt esterification, its polymer, the resulting product of anti-inflammatory and antipyretic analgesics than free A aspirin is more long-lasting. According to literature, said the inventor of aspirin was Felix Hoffman of Germany, but this invention, plays a very important role in a Jewish chemist Arthur Ai Xing Green. Artur Ai Xing Green's bitter story takes place in 1934-1949. In 1934, Felix Hoffman claimed that he invented aspirin. Then Germany is in the dark period of Nazi persecution of Jews intensified. In this case, the arrogant Nazi rulers more reluctant to recognize the inventor of aspirin in the fact that the Jews, so they would be wrong to wear the crown of the inventor Felix Hoffmann, a person's head. "Germanic racial superiority theory" laced with gold. Nazi rulers in order to block the mouth of Artur Ai Xing Green, also put into a concentration camp. After World War II, about 1949, Artur Ai Xing Green raised this issue, but he soon died. Since then, this matter will go down the drain. British physician, historian Walter Snyder twists and turns to get the license of Bayer AG, Germany, access to all files in the Bayer laboratory, and finally restore the hard facts of the history of the true face of this invention. He pointed out: the invention of aspirin, Artur Ai Xing Green contributed. The fact is that in 1897, Felix Hoffman is indeed the first synthesized the main substances constitute aspirin, but he is under the guidance of his superiors - the well-known chemist Arthur Ai Xing Green and completely Ai Xing Green technology routes only to be successful.

Chinese pharmaceutical intermediates industry recent developments

{ 03:26, 28/5/2012 } { 0 comments } { Link }
The so-called pharmaceutical intermediates, in fact, for drug synthesis process in a number of chemical raw materials or chemical products. This chemical products, does not require drug production licenses in the ordinary chemical plant can produce some level, can be used for the synthesis of pharmaceuticals. China's beta-lactam antibiotics after nearly 50 years of development, has formed a complete production system. Almost all beta-lactam antibiotics (except for the patent period of the species) in China can produce low cost, penicillin production in the world's top export supply the international market; the cephalosporins basic self-sufficient, can buy part of exports. Intermediates in China, and beta-lactam antibiotics, supporting all be able to produce their own, in addition to semi-synthetic antibiotic nucleus 7-ACA and 7-ADCA need some imported, all of the side chain intermediates can be produced, and a large number of exports. The main supporting intermediate phenylacetic acid to beta-lactam antibiotics, for example, our existing manufacturers phenylacetate 30, with a total production capacity of about 20,000 tons. But the small scale of most enterprises, the largest annual output of 2000 tons, most other annual output of hundreds of tons. Domestic the phenylacetate total demand in 2003 is about 1.4 million tons, the consumption structure as follows: penicillin G accounted for 85%, other medical (4%), spices (7%), pesticides and other areas accounted for 4%. With the development of domestic spices, medicine, pesticide and other industries, acid demand will increase further. Expected in 2005, China's pharmaceutical industry will consume about 14,000 tons of phenylacetic acid, the pesticide industry will consume 500 tons, the spice industry consumption of about 2000 tons. Plus other areas of consumption, expected domestic phenylacetate total demand will reach 18,000 tons in 2005. At present, China has developed and put into mass production quinolones norfloxacin, ciprofloxacin, ofloxacin, enoxacin, lomefloxacin, fleroxacin magnitude. Including norfloxacin, ciprofloxacin, ofloxacin, producing the largest amount, 98% of the total output of accounting for the fluoroquinolone antibacterial drug. The quinolones general condensation with piperazine (or piperazine) derived from fluorine-containing benzene ring synthesis of fluorinated quinoline compounds. Abundant fluorite reserves in China, which is one of the largest countries of the fluorine-containing drugs and intermediates production, there are more than 80% of the fluorine-containing intermediates for export. Overall, the development of fluorobenzene intermediates in China earlier, the current production capacity is generally excess; the benzotrifluoride class intermediate development of late, with fast development in recent years; and heterocyclic aromatic compounds, especially fluorinated pyridine class, our present, only the individual research institutes and manufacturers with the synthesis of fluorinated pyridines intermediates, fluorine-containing pyridine intermediates will become one of the main directions of domestic fluorine-containing intermediates, R & D in the next few years. China has become the world's largest production of the antipyretic analgesics, aspirin, paracetamol, dipyrone and other varieties yield surpassed tons, non-phenacetin, aminopyrine, security for more than forests and other species of output over 1000 tons. Of antipyretic analgesics output growth is expected that the future will increase rate of about 8%. Antipyretic analgesics supporting the production of intermediates production, and production enterprises. With the growth of antipyretic analgesics, and its intermediates has also received considerable development. Domestic paracetamol consumption in 2003 a rapid increase in exports also showed a rapid growth, the export volume of 28,163 tons, an increase of annual export volume amounted to about 1 times. The first half of 2004, its export growth slowed, but still an increase, 2004 to May paracetamol exports of 12,501 tons, slightly higher than the same period last year. The aminophenol important intermediates for the synthesis of paracetamol in recent years, rapid growth. At present, China's annual production of aminophenol is about 32,000 tons, is expected to 2005, domestic paracetamol production will reach more than 50,000 tons, the pharmaceutical industry will consume 45,000 tons aminophenol, coupled with the application in other fields, 2005 aminophenol total demand of about 50,000 tons, a larger gap in the market, development and utilization of broad prospects. Throughout the industry, the production of pharmaceutical intermediates in China has six characteristics: First, the production enterprises to the private sector, operating flexibility, and investment in small, basically a few million to 20 million yuan; manufacturers The geographical distribution is relatively concentrated, mainly located in Taizhou, Zhejiang and Jiangsujintan areas; Third, as the country's increasing emphasis on environmental issues, environmental treatment facilities for production enterprises to build pressure increases; four product updates faster. A product is generally 3 to 5 years after the market, its profit margin dropped significantly, forcing companies must constantly develop new products and continuously improving production process in order to maintain high production and profits; five is due to the production of pharmaceutical intermediates, high-profit chemical products, both the production process is basically the same, so there will be a growing number of small chemical companies joined the ranks of the production of pharmaceutical intermediates, leading to the disorder in an increasingly competitive industry; six, compared with the raw material drug production intermediate low profit margins, pharmaceutical raw materials and the production of pharmaceutical intermediates, and a result, some enterprises have not only the production of intermediates, and also use their own advantage, and began producing bulk drugs.

What will you bring home from your exotic holiday Parasites

Imagine a beautiful freshwater stream; the soft gurgle of the crystal clear water as it gently flows over round, smooth river rocks; little silvery fish darting here and there. You pull off your shoes and socks and dip your toes in the cool stream. You bend down and sip the refreshing water. Imagine a cabin near a freshwater lake. You, alone in the calm lake in your boat, your fishing rod cast in the water, reeling in a lovely shimmering fish. You take it to the cabin, gut it, clean it, roast it, and watch the family enjoying your fresh catch. Two beautiful, peaceful scenarios, right? Wrong! If in a few weeks you find an itchy rash all over. Wrong! If within a short time you start getting severe abdominal pain and nausea. Why? Along with the lovely memories, you may have picked up some Schistosoma in the freshwater, or perhaps some Clonorchis Sinensis (human liver fluke) from your delicious freshwater fish!So what happens next? First of all, let us see what these two nasties are. The Schistosome. These are parasitic flatworms that live in freshwater in the tropics. The parasites must first infect and mature in freshwater snails, which are their intermediate hosts. These parasites then enter a human body through human skin when it comes into contact with freshwater that contains infected snails. The parasites penetrate our skin, the worms grow inside our blood vessels and produce eggs. Some of these eggs are eliminated by the body through stools and urine. But more than half of them remain in the body, and scar and damage vital organs. The symptoms of Schistomiasis are caused by the body's reaction to the eggs, and not by the worms. Clonorchis sinensis. Clonorchis sinensis or the Human liver Fluke is a parasite that lives in the human liver, mainly in the bile duct and gall bladder, and feeds on bile. The eggs of this parasite float in freshwater until they are swallowed by snails. In the snail's body, the miracidium hatches from the eggs, develops into a sporocyst, which in turn houses the redia. Once the redia mature, they actively exit the snail's body, and search for a host fish. They bore their way into the fish's body and become parasites living in the fish. There they form a protective metacercarial cyst to encapsulate their bodies. Once this fish is eaten by humans, the cyst prevents human gastric acid from digesting the parasites, and the parasites make their home in the human liver. In the liver, they reproduce asexually, producing eggs ever few seconds resulting in a heavy parasitic population. How do we get rid of these harmful parasites? Not to fear, they are quite easy to destroy, thanks to a very potent medicine called Praziquantel. Praziquantel was developed in Germany in the laboratories for parasitological research of Merck and Bayer. Praziquante is a trematodicide prescribed for the oral treatment of schistosome infections and infections due to the human liver fluke. It belongs to a class of drugs known as antihelmintics. It works in two ways. It kills parasites, and it paralyses them to loosen their hold on the walls of our blood vessels so that our body can eliminate them easily and naturally. The wonderful thing about Praziquantel is that it generally works with just a few doses taken in one single day! However, depending on the magnitude of the infection, and your body's response to the medicine, the doctor may recommend an additional day or two of doses. Naturally, it does have some side effects and advocates certain precautions.
