Effects of Drugs and Alcohol to the Body Essay Example for Free

Effects of Drugs and Alcohol to the Body Essay The effects of drugs and alcohol may vary on the kind of drug, the dosage, the frequency, the persons’ body element and metabolism, and the type of personality. According to the American Academy of child and adolescent psychiatry, 20 million adults in the United States abused alcohol and half of these abusers were teenagers. Teens usually perceive drugs and alcohols as a solution to their problems, to gain popularity, to become active, to have pleasure and at times due to curiosity and peer pressure. They simply disregard the fact that this will only harm their bodies, mess up their entire lives, and could even lead them to death. The effects of these substances are danger to human brain and body. Drugs are considered pervasive. It compromises the ability of the body to function well. It affects both physical and psychological aspects. Over consumption or tolerance to this effect can lead to physiological problem. Pathophysiology traces alcohol primarily on blood. Because alcohols are permeable to the cell membrane of the body, it can easily diffuse to the bloodstream and causes â€Å"blood-sludging† of which blood vessels are being plug up while the tissues and oxygen of the body are being starve, thus causing cell death. Further breaking of the blood vessels and cell death causes malfunction of the system of the body causing excessive bleeding or hemorrhage, predisposing factor of cancer and leading to death. Other effect of high concentration alcohol level on the blood is the depletion of red and white blood count which is the main component of the blood. Common blood disorders are anemia, bone marrow depression, and inability to fight infections. The first step in alcohol abuse treatment is detoxification. A doctor will give a prescription for one to have a high dose of medication for the first day of not drinking alcohol. In the succeeding days of the week, the patient will slowly lessen the dose of the medicine. The medicine usually reduces withdrawal symptoms â€Å"A breathalyser may be used to confirm that you are not drinking† (http://www.patient.co.uk/showdoc/27000488/What is detoxification?). It is important for the patient to have the support of his family amidst his medication process in order for him to gain motivation and inspiration. In treating drug addicts, it is advised for them to undergo Cognitive behavior therapy. This kind of therapy is also used in treating alcohol abuse. Many drugs and alcohol users are from a situation of hardships and problems in life. They find drugs and alcohol as coping mechanism. â€Å"Cognitive behavior therapy is based on the idea that feelings and behaviors are caused by a persons thoughts, not on outside stimuli like people, situations and events† (http://alcoholism.about.com/od/effect/The_Effects_of_Alcohol_and_Drugs.htm). In this kind of therapy, the therapist will make the patient recognized the situations and reasons why he is taking drugs and alcohol. The first thing taught in this therapy is how to do away from situations like those and how they can cope with it. The Cognitive Therapy may lasts until 12 sessions or depending upon the progress of the patient. Again, family support is vital in the process of treatment. BIBLIOGRAPHY Dunlap, M. P..

Kochs Postulates :: essays research papers

Koch’s Postulates   Ã‚  Ã‚  Ã‚  Ã‚  Introduction Koch created four guidelines to determine the causal agents of disease in humans, animals, and plants. Koch proved that a disease-causing agent could be transferred from one organism to another and create the same illness. Isolation of pure cultures and the introduction of the disease-causing agent to a healthy organism will transmit the disease and infect the inoculated organism. Koch’s four guidelines by which one must follow to transmit a disease from an infected organism to a healthy one are as followed: 1. The specific organism should be shown to be present in all cases of animals suffering from a specific disease but should not be found in healthy animals. 2. The specific microorganism should be isolated from the diseased animal and grown in pure culture on artificial laboratory media. 3. This freshly isolated microorganism, when inoculated into a healthy laboratory animal, should cause the same disease seen in the original animal. 4. The microorganism should be reisolated in pure culture from the experimental infection. In this exercise, Penicillium was utilized, a common, safe, mold. Certain species of Penicillium will spoil fruits, vegetables, grains, and grasses. Other species will ripen various chesses. Still, other species are used in the production of antibiotics. The species of Penicillium, italicum is provided for the lab because of its pronounced hyphae. Penicillium italicum, along with Penicillium digitatum attack citrus fruits post-harvest. In this experiment, the effect of Penicillium italicum on two types of citrus fruits and one non-citrus fruits were tested.   Ã‚  Ã‚  Ã‚  Ã‚  Materials & Methods 1. Pick several appropriate fruits. 2. Gently was fruit in cool, soapy water, using a scrub brush on the citrus fruits, then rinse thoroughly with cool running tap water. 3. Place citrus in a beaker and cover with a 10% bleach solution. Let soak for 10 minutes. 4. Rinse thoroughly with cool running tap water for 10 minutes. 5. Flame sterilize a teasing needle, cool, then pierce skin of disinfected fruit. 6. Unscrew cap on Penicilium italicum culture tube with one hand and flame the mouth of the tube. 7. Using the first three fingers of your writing hand, obtain a sterile applicator stick and remove a small sample of the fungus and smear over the puncture wound of the fruit. 8. Flame tube and recap. Discard swabs appropriately. 9. Obtain a second sample with a sterile applicator stick and smear over an unpunctured section of the fruit. 10. Flame tube and recap. Discard swabs appropriately. 11. Maintain a control for the experiment.

Leadership Principles for Effective Change

â€Å"Change only happens when each person makes a decision to implement the change.† It is very easy to talk about dreams and talk about plans. But without the commitment to follow through and implement what needs to be done, such talk is merely wishful thinking. Every person involved in the process should implement change because everyone involved should do his part. Otherwise, the change will be incomplete. In order to manage change, the tasks that each person needs to do should be written down for implementation and monitoring. This may seem difficult and out of culture but it can do a lot in making people accountable and willing to implement the changes discussed by the organization. â€Å"A clearly defined vision of the end result enables all the people to define the most efficient path for accomplishing the results.† A vision is a powerful thing. It helps refine and enhance the direction of the organization. When a vision is clearly stated and understood by the members of the organization, they can formulate their strategies and align their activities toward the vision of the organization. Out of the vision, the strategies of the organization can be formulated. Some strategies, however, may appear not to support the end result as stated in the vision. To ensure that the strategies are aligned with the vision, an organization needs to promote its vision and its mission to its employees and to its management team. During the sessions of strategic planning, the vision should be inculcated into the minds and practices of the organization so that the strategies formulated support the fulfillment of the vision. With a clearly defined vision, the people know what they are working for. When they know what they are working for, they can search for the best approach there is. Select the two principles you believe are the most important to follow when managing change and describe why you feel these are essential. Describe some specific techniques that can be used to manage change in an organization. Explain how these techniques are consistent with the principles you selected. 1.Thought processes and relationship dynamics are fundamental if change is to be successful. 2.Change only happens when each person makes a decision to implement the change. 3.People fear change it â€Å"happens† to them. 4.Given the freedom to do so, people will build quality into their work as a matter of personal pride. 5.Traditional organizational systems treat people like children and expect them to act like adults. 6.†Truth† is more important during periods of change and uncertainty than â€Å"good news.† 7.Trust is earned by those who demonstrate consistent behavior and clearly defined values. 8.People who work are capable of doing much more than they are doing. 9.The intrinsic rewards of a project are often more important than the material rewards and recognition. 10. A clearly defined vision of the end result enables all the people to define the most efficient path for accomplishing the results. 11. The more input people have into defining the changes that will affect their work, the more they will take ownership for the results. 12. To change the individual, change the system.

What Is a Buffer and How Does It Work

The use of buffers is an important concept in acid-base chemistry. Heres a look at what buffers are and how they function. What Is a Buffer? There are two key terms associated with buffers. A buffer is an aqueous solution that has a highly stable pH. A buffering agent is a weak acid or weak base that helps maintain the pH of an aqueous solution after adding another acid or base. If you add an acid or a base to a buffered solution, its pH will not change significantly. Similarly, adding water to a buffer or allowing water to evaporate will not change the pH of a buffer. How Do You Make a Buffer? A buffer is made by mixing a large volume of a weak acid or weak base together with its conjugate. A weak acid and its conjugate base can remain in solution without neutralizing each other. The same is true for a weak base and its conjugate acid. How Do Buffers Work? When hydrogen ions are added to a buffer, they will be neutralized by the base in the buffer. Hydroxide ions will be neutralized by the acid. These neutralization reactions will not have much effect on the overall pH of the buffer solution. When you select an acid for a buffer solution, choose an acid that has a pKa close to your desired pH. This will give your buffer nearly equivalent amounts of acid and conjugate base so it will be able to neutralize as much H and OH- as possible. Sources Atkins, Peter; Jones, Loretta (2005).
