Individual nasal symptoms (congestion and rhinorrhea) at 2 weeks: Evidence was 62 discount 30mg nimodipine mastercard, 90 insufficient to support the use of one treatment over the other based on two trials with high risk of bias and inconsistent order nimodipine 30 mg with mastercard, imprecise results buy generic nimodipine 30mg online. Individual nasal symptoms (congestion effective nimodipine 30mg, rhinorrhea, sneezing, and itch) at 6 weeks: Evidence was insufficient to support the use of one treatment over the other based on one 132 trial with high risk of bias and imprecise results. These results are based on trials using three of five oral selective antihistamines (60 percent) and two of eight intranasal corticosteroids (25 percent). Nasal Symptoms 62, 90 Evidence for the assessment of individual nasal symptoms comes from two of five trials 132 (407 of 1201 patients) that assessed nasal symptoms at 2 weeks, and one trial that assessed nasal symptoms at 6 weeks. All three trials were rated poor quality due to noncomparable groups 132 62, 90 at baseline and inappropriate analysis of results (not intention to treat ). At 6 weeks, Di Lorenzo (2004) showed a statistically nonsignificant treatment effect of 0. Evidence for the outcome of congestion at 2 weeks was insufficient to support the use of one 62, 90 treatment over the other. Two poor quality trials with high risk of bias reported inconsistent and imprecise treatment effects. For the outcome of congestion at 6 weeks, evidence also is 132 insufficient to support the use of one treatment over the other. One poor quality trial with a high risk of bias reported an imprecise treatment effect. At 6 132 weeks, Di Lorenzo (2004) also showed a statistically nonsignificant treatment effect of 0. Evidence for the outcome of rhinorrhea at 2 weeks was insufficient to support the use of one 62, 90 treatment over the other. Two poor quality trials with high risk of bias reported inconsistent and imprecise treatment effects. For the outcome of rhinorrhea at 6 weeks, evidence also is 132 insufficient to support the use of one treatment over the other. One poor quality trial with a high risk of bias reported an imprecise treatment effect. At 6 weeks, Di Lorenzo (2004) showed a statistically nonsignificant treatment effect of 0. Evidence for the outcome of sneezing at 2 weeks was insufficient to support the use of one 62, 90 treatment over the other. Two poor quality trials with high risk of bias reported consistent but imprecise treatment effects. For the outcome of rhinorrhea at 6 weeks, evidence also is 132 insufficient to support the use of one treatment over the other. One poor quality trial with a high risk of bias reported an imprecise treatment effect. At 6 weeks, Di Lorenzo (2004) reported a statistically significant treatment effect of 0. Evidence for the outcome of nasal itch at 2 weeks was insufficient to support the use of one 62, 90 treatment over the other. Two poor quality trials with high risk of bias reported consistent but imprecise treatment effects. For the outcome of nasal itch at 6 weeks, evidence also is 132 insufficient to support the use of one treatment over the other. One poor quality trial with a high risk of bias reported an imprecise treatment effect. One of these was a fair quality trial of 300 patients (42 percent of patients reporting this outcome). This was a poor quality trial of 345 patients (49 percent of patients reporting this outcome). Fifty-eight percent of patients were in poor quality trials, and 42 percent were in a fair quality trial. The evidence was therefore insufficient to support the use of one treatment over the other for this outcome. The larger of 131 132 these (92 percent of patients reporting this outcome) was rated good quality, and the smaller (n=40) was rated poor quality due to noncomparable groups at baseline. At 6 weeks, the latter 132 trial showed a statistically nonsignificant treatment effect of 0. The risk of bias was considered low; 92 percent of patients reporting this outcome were in the good quality trial. Eye Symptoms 90 131 Two trials assessed eye symptoms, one at 2 weeks (N=345) and one at 8 weeks (N=454). This trial was rated poor quality due to inappropriate analysis of results (not intention to treat).
A human cell typically consists of flexible membranes that enclose cytoplasm generic nimodipine 30mg line, a water-based cellular fluid together with a variety of tiny functioning units called organelles discount 30 mg nimodipine mastercard. A tissue is a group of many similar cells (though sometimes composed of a few related types) that work together to perform a specific function purchase nimodipine 30 mg otc. An organ system is a group of organs that work together to perform major functions or meet physiological needs of the body nimodipine 30 mg for sale. Assigning organs to organ systems can be imprecise since organs that “belong” to one system can also have functions integral to another system. An organism is a living being that has a cellular structure and that can independently perform all physiologic functions necessary for life. In multicellular organisms, including humans, all cells, tissues, organs, and organ systems of the body work together to maintain the life and health of the organism. These many functions can be summarized in terms of a few that we might consider definitive of human life: organization, metabolism, responsiveness, movement, development, and reproduction. Organization A human body consists of trillions of cells organized in a way that maintains distinct internal compartments. These compartments keep body cells separated from external environmental threats and keep the cells moist and nourished. They also separate internal body fluids from the countless microorganisms that grow on body surfaces, including the lining of certain tracts, or passageways. The intestinal tract, for example, is home to even more bacteria cells than the total of all human cells in the body, yet these bacteria are outside the body and cannot be allowed to circulate freely inside the body. Cells, for example, have a cell membrane (also referred to as the plasma membrane) that keeps the intracellular environment—the fluids and organelles—separate from the extracellular environment. Blood vessels keep blood inside a closed circulatory system, and nerves and muscles are wrapped in connective tissue sheaths that separate them from surrounding structures. In the chest and abdomen, a variety of internal membranes keep major organs such as the lungs, heart, and kidneys separate from others. The body’s largest organ system is the integumentary system, which includes the skin and its associated structures, such as hair and nails. The surface tissue of skin is a barrier that protects internal structures and fluids from potentially harmful microorganisms and other toxins. Metabolism The first law of thermodynamics holds that energy can neither be created nor destroyed—it can only change form. Your basic function as an organism is to consume (ingest) energy and molecules in the foods you eat, convert some of it into fuel for movement, sustain your body functions, and build and maintain your body structures. Your body can assemble, by utilizing energy, the complex chemicals it needs by combining small molecules derived from the foods you eat • Catabolism is the process by which larger more complex substances are broken down into smaller simpler molecules. The complex molecules found in foods are broken down so the body can use their parts to assemble the structures and substances needed for life. Responsiveness Responsiveness is the ability of an organism to adjust to changes in its internal and external environments. An example of responsiveness to external stimuli could include moving toward sources of food and water and away from perceived dangers. Changes in an organism’s internal environment, such as increased body temperature, can cause the responses of sweating and the dilation of blood vessels in the skin in order to decrease body temperature, as shown by the runners in Figure 1. Movement Human movement includes not only actions at the joints of the body, but also the motion of individual organs and even individual cells. As you read these words, red and white blood cells are moving throughout your body, muscle cells are contracting and relaxing to maintain your posture and to focus your vision, and glands are secreting chemicals to regulate body functions. Your body is coordinating the action of entire muscle groups to enable you to move air into and out of your lungs, to push blood throughout your body, and to propel the food you have eaten through your digestive tract. Consciously, 16 Chapter 1 | An Introduction to the Human Body of course, you contract your skeletal muscles to move the bones of your skeleton to get from one place to another (as the runners are doing in Figure 1. Anatomic structures and physiological processes allow runners to coordinate the action of muscle groups and sweat in response to rising internal body temperature. Development includes the process of differentiation, in which unspecialized cells become specialized in structure and function to perform certain tasks in the body. Development also includes the processes of growth and repair, both of which involve cell differentiation. Humans, like all multicellular organisms, grow by increasing the number of existing cells, increasing the amount of non-cellular material around cells (such as mineral deposits in bone), and, within very narrow limits, increasing the size of existing cells. Because death will come to all complex organisms, without reproduction, the line of organisms would end. Earth and its atmosphere have provided us with air to breathe, water to drink, and food to eat, but these are not the only requirements for survival. Although you may rarely think about it, you also cannot live outside of a certain range of temperature and pressure that the surface of our planet and its atmosphere provides. The three basic classes of nutrients are water, the energy-yielding and body-building nutrients, and the micronutrients (vitamins and minerals).
