Prostaglandins are highly potent substances that are not stored but are produced as needed by cell membranes in virtually every body tissue. Anesthesia Anesthesia is a state in which the patient feels no pain. This may range from blocking the sensation of one small part of the body to total unconsciousness. Whenever you have surgery, you usually have some kind of anesthesia. The anesthesia allows the surgeon to perform the surgery painlessly. There are many different types of anesthesia. General Anesthesia When you have general anesthesia you are completely unaware of your surroundings. The messages of pain or sensations that normally travel to your brain for processing are no longer processed. Usually with General Anesthesia your breathing is controlled with a breathing tube placed in your airway after you are asleep. Spinal Anesthesia With spinal anesthesia you are given an injection in your lower back. The medication blocks the messages carried to the brain from the nerves in the lower half of your body. ...read more.


When you take a pill the drug goes from the stomach into the intestine and then into the liver before circulating to the rest of the body. If the drug is easily broken down by the liver then very little of the drug reaches the body. Once absorbed by your body, the drug spreads throughout the body in blood vessels. They provide a way for the drug travels from one area to another area. Once a drug has finished doing its job it is empty from the body. This can be done in many ways such as in urine, the gut, in fasces, lungs and through sweat. Before a medication can be sold it must go through thorough safety testing. People will work with doctors and some researchers to study if it is safe enough to use and if there are any dangerous side effects and how well it works. Before a medication can be sold to the public it goes through several stages. It takes 10 - 15 years to develop and test a new medication to ensure that it's safe and effective for people to use. ...read more.

    Washing the solid product well and recrystallising it may reduce the degree of contamination but it might even have the reverse effect. This is because if you start off with aspirin tablets, they may be hydrolysed in humid conditions, producing salicylic acid and ethanoic acid again: Thin-layerchromatography A fairly simple

    1.5067 - 1.4850 = 0.0217g Percentage by mass of aspirin (percent purity) = 1.4850 x 100 = 98.56% 1.5067 Conclusion The aim of the investigation was to prepare aspirin and determine its purity by using different experimental techniques. The purity of the prepared aspirin was then compared to the purity of pure aspirin via the same experimental techniques.

    The number of moles of the NBS solution and vitamin C has a ratio of 1:1, so therefore: Orange: The number of moles of the NBS solution used in the orange sample was 3.633 x 10-3 moles so therefore the sample of orange had 3.633 x 10-3 moles of vitamin C present in it.

    The most important part of this information is that when hydrolysing an ester with NaOH and phenylalanine indicator the mixture will change frompink to colourless. Safety Organic compounds - Most organic compounds are volatile and easily flammable so during the wet tests we cannot use a Bunsen burner Sodium - Sodium is highly flammable and corrosive.

  2. the analysis of aspirin tablet

    When the number of mole of sodium hydroxide used to hydrolyze the acetylsalicylic acid is calculated, the number of mole of acetylsalicylic acid and the mass of acetylsalicylic acid present in each aspirin tablet can be also calculated.
