Blood flow through the heart and round the body is maintained by contraction of the atria in unison followed by contraction of the ventricles in unison. The pulmonary and aortic valves close while the atria contract; the tricuspid and bicuspid valves close while the ventricles contract. This prevents backflow of blood. The contraction phase is known as systole and the relaxation phase of the heart is known as diastole. Cardiac output is the volume of blood pumped out of the left ventricle every minute and is a function of the stroke volume and heart rate.

Cryotherapy Use of liquid nitrogen for destroy warts. Multiple treatment over several months. Electrosurgery Under local anaesthetic, the wart is pared away and the base burned by diathermy or cautery.

Osteomalacia is a deficiency disease. Insufficient vitamin D leads to low plasma calcium levels.

The absorbing membrane for nutrients and drugs is the mucous membrane of the epithelial cells lining the gastrointestinal tract. General factors affecting diffusion across cell membranes, considered above, apply in addition to the pH of gastrointestinal contents: surface area of the gastrointestinal tract; gastric emptying and intestinal transit time; blood flow from the gastrointestinal tract; plasma protein binding; active transport mechanisms and drug formulation. This is known as first pass metabolism, which can result in considerable loss of activity for some drugs on first pass through the liver.

Third generation β-blockers also cause peripheral vasodilation and do not adversely affect plasma lipid profiles. An example is celiprolol. Calcium channel blockers are used to treat ischaemic heart disease, arrhythmia and hypertension.

This is especially important for new drugs as adverse reactions can be missed during clinical trials. Patients as well as health care professionals can use the yellow card scheme. A new system of reporting adverse reactions, the National Reporting and Learning System has recently been set up by the National Patient Safety Agency.

Moreover, like antiepileptic drugs, local anaesthetics show use dependence in that they preferentially block neurons that are transmitting impulses at high frequency (as pain sensory neurons do). open closed inactivated sodium ion channels local anaesthetic ionized local anaesthetic neuronal membrane diffusion Figure Local anaesthetics are weak bases and at the slightly alkaline pH of body fluids, they exist in both ionized and unionized forms in equilibrium. Only the unionized form can reach its site of action, which is inside the neuron. This is because the drug has to be in a xyzal coumadin 4mg soluble form to diffuse through the myelin sheath and neuronal membrane.

Tuberculosis is caused by Mycobacterium tuberculosis and Mycobacterium bovis. Both organisms can cause tuberculosis in man and cattle. A related organism is Mycobacterium leprae, which is the cause of leprosy. Despite vaccination programmes in many parts of the world, tuberculosis remains the largest single xyzal coumadin 4mg of death by infectious disease, causing three million deaths worldwide annually.

In order to avoid this relapse, the dose is often increased again and maintained. The danger then is that the patient becomes dependent on corticosteroids. Sometimes pulse doses of corticosteroids are used to suppress inflammation while longer term and slower acting DMARDs are being started. Corticosteroids suppress all phases of the inflammatory response, including the early swelling, redness and pain and the later stages seen in chronic inflammation. Circulating lymphocytes and macrophages are reduced in number and the formation of prostaglandins and leukotrienes is inhibited via inhibition of phospholipase A enzyme that converts cell membrane phospholipids into arachidonic acid.
