The of rural India are met by groundwater and 20 percent Government of India launched the National Water from surface water erectile dysfunction quad mix order fildena no prescription. The situation is just the reverse in Supply and Sanitation Program in 1954 as an overall urban areas erectile dysfunction treatment muse buy fildena 100 mg without a prescription, where 80 percent needs are met by surface part of the National Health Plan erectile dysfunction joliet fildena 150 mg low cost. This water is soft and clean, but has The water is said to be potable when it devoid of to be protected against contamination. Rainwater is an pathogenic agents, harmful chemical substances, and important source of water in some countries like free from color, odor and usable for domestic purposes. Approximately 97 percent of water being the salty sea Ponds and tanks: These are the only water sources in water and 2 percent is frozen in glaciers and polar ice caps. These are used for drinking, bathing and Thus only 1 percent of the world’s water is usable to human washing by human beings and also for bathing of animals. In some cases wells are dug inside the tanks or Water evaporates from the sea and the land and by their side to obtain from them water reaching there by forms clouds. Water falling on land The methods of reducing water pollution of tanks and remains upland or goes under ground by percolation. Guinea worm subsoil or under groundwater, it is present in the whole disease occurs because of direct contact between man of the porous mass. The quality of subsoil water drawn Natural lakes and impounded reservoirs: Lakes are by wells, tube-wells or springs depends on the nature of large natural collection of water. Impounded or artificial the formation on which it rests and the number or depth reservoirs are made by making dams across streams. They form a common source of water supply to large Groundwater is obtained from wells and springs. The purity of water in an impounded reservoir depends upon the type of catchment area. They are of three types-shallow wells, deep wells and Water is usually supplied to towns after purification and artesian wells. An open- Rivers and streams: These form a major source of well is a pit dug out in the ground to reach the water water supply. However, rivers Sometimes a hand-pump or motor pump may also be may be polluted by human and animal excreta, refuse installed in an open well. Natural a tubing through which water is obtained with the help purification does take place to some extent (through of a pump. As per this definition, an ordinary hand-pump sedimentation, dilution, oxidation, aeration, ultraviolet is also a tube-well, but in common usage the term tube- rays, sunlight and the action of aquatic plants and well implies a pump operated through a motor. Hence river water is supplied to the cities refer to the actual depth of the water level from ground. A shallow River bank near the village may be marked into 5 well draws water from the first water table which is near divisions for safer supply. Such a well may be polluted by bacteria and be indicated by flags from upstream to downstream for other impurities which percolate down along with rain different uses-drinking, bathing, washing of clothes and or spill water. Some natural purification takes place utensils; watering of animals, and bathing of animals, through the porous soil (which acts as a filter) and in that order. Continuous disinfection (by bleaching powder, for example) is necessary to have safe drinking water from shallow wells. This water is much cleaner and bacterio- logically safer, but is often hard because of a high mineral content. The minerals (calcium and magnesium carbo- nates, sulphates and chlorides) are derived from the lime- stone formations. Deep wells may be sometimes several hundred feet deep depending upon the location of the impervious layer. The quantity of water that can be drawn from a deep well is usually more than that avai- 53 Fig. In Delhi, many tube-wells are used to supplement the water supply from Yamuna river. Artesian well: The water source for percolation in this case is at a very high level.

This reflex will result in activation of sympathetic nerves to the heart and blood vessels and a suppression of vagal activation to the heart impotence yahoo purchase fildena american express. The result erectile dysfunction medication cheap order fildena 50 mg, following the initial effect of the nitroprusside erectile dysfunction treatment auckland generic fildena 100 mg visa, is to increase heart rate, myocardial contractility, and stroke volume. Together, these effects attenuate the initial drop in blood pressure caused by the drug. Depending on the balance between myocardial stimulatory effects on rate and contractility versus the final level of blood pressure, myocardial oxygen consumption may actually increase 1 to 2 minutes after administration of nitroprusside. An older form of treatment for severe chronic hypertension was to use combined pharmacological alpha- and beta-receptor blockade. In this condition, blood pressure regulation in the patient becomes extremely dependent on: A. Blockade of all adrenergic receptors in the body by combined drug therapy results in a “chemical” sympathectomy. Blood pressure in patients on this therapy becomes exquisitely dependent upon blood volume. Therefore, factors that affect salt and water balance in the body have profound influence over blood pressure (e. The neural arms of the chemoreceptor and central nervous system ischemic reflexes would not function well, if at all, in an individual with chemical sympathectomy. Adrenal or any other catecholamines would have limited effect on the cardiovascular system in which adrenergic receptors were blocked (although the diminution of response would depend on the level of the blockade and the magnitude of catecholamine concentration). The effect of vascular resistance on blood pressure would be markedly blunted by alpha blockade. She is given this drug as a skin patch, which is to be worn during the day and which releases small amounts of this vasodilator into her circulation continuously through the skin. She is also given nitroglycerin tablets to be taken in case of an anginal attack or as a prophylaxis against angina in anticipation of physical exertion beyond normal daily activities. During one morning, a couple of hours after applying her nitroglycerin skin patch, she takes a nitroglycerin tablet in anticipation of doing some gardening but decides to lie down for a few moments before starting work. Within 10 minutes of lying down, the patient bolts from her supine position to answer her telephone. However, within seconds of rising from the supine to the standing position, she becomes light-headed and dizzy. Her heart rate starts to increase rapidly and she can feel her heart pounding in her chest. Within a couple of steps, her vision narrows and blackens and she collapses onto the floor unconscious. Shortly after this episode, the patient regains consciousness and is able to stand only after slowly arising. What cardiovascular phenomenon is most likely responsible for the loss of consciousness in this patient? What changes in blood volume distribution normally occur immediately when one moves from a supine to a standing position? What immediate effects do these have on cardiac output and arterial blood pressure? What reflex mechanisms are brought into play in response to these changes in blood pressure? Nitroglycerin is a rapidly absorbed, quick-acting direct vasodilator that relaxes smooth muscle in veins more than arteries. How does this selective effect of nitroglycerin relate to the responses of the patient suddenly standing? Loss of consciousness can result from numerous factors, but the most likely related to the cardiovascular system is a sudden severe drop in blood pressure below the autoregulatory limit of the cerebral circulation. This would cause a drop in blood flow and oxygen supply to the brain that would likely induce neurological effects such as darkening vision, dizziness, and fainting.
