Abortion Final Essay Example | Topics and Well Written Essays - 1750 words

Abortion Final - Essay Example So questions arise like, is the mother who has aborted the child killer? Or, is the male partner of that woman equally responsible for this abortion/murder? Abortion is wrong at any stage, even at embryonic stage. If we will allow abortion for an earlier stage, then people will take advantage of this relaxation and will try to abort to baby even at a more mature stage which is called as fetus. So the main point of writing this paper is to argue that abortion should remain a crime except for a few genuine reasons. The term ‘abortion’ refers to those acts that are aimed at ending pregnancy. It also refers to forcing out the fetus or embryo form the womb of mother before it could be able to survive on its own: before complete child development that takes about 9 months in total after conception. If this happens accidentally, it is referred as ‘miscarriage’. In this paper we are going to present some common ethical dilemmas against abortion. Then later we will analyze those dilemmas. Giving birth to children is an important part of personal as well as social life. Nevertheless, there are people who decide to have an abortion due to various reasons (Graber, M. 1996). We are also going to discuss the methods that are generally used to abort a baby at different stages of the child development. We then have a look at historical and legislation frontiers. We will also discuss this issue in the light of normative ethics. The reason behind an abortion varies from society to society and culture to culture. Some societies hate girls and abort if the gender test shows that they are going to have a baby girl. On the other hand, many parents or partners change their minds to have a baby and abort the baby. In cases of rapes, rape victims are used to abort the baby because this act is wrong altogether. One child policy that prevails in China is also one of the reasons behind abortions. In some poor countries,

Explain how the relationship between the dose of drug given to an Essay

Explain how the relationship between the dose of drug given to an individual and the concentration of drug molecules - Essay Example These factors are discussed in more detail below, based on the description of Goodman, et al. (2011, ch. 2). The characteristics of the drug molecule itself that affect the drug’s concentration at the receptor site include its molecular size, degree of ionization, lipid solubility, and its affinity for serum and tissue proteins. The plasma membrane (of skin or intestinal cells, for example) is a common barrier to drug distribution; drugs that are not lipid soluble will not be able to permeate the membrane and not reach the target site. A drug of small molecular size will travel more easily through the membranes than a larger molecule, reaching the target in higher concentrations. Ionized molecules, and those that bind to proteins, also have difficulties in passing through the membrane. If the drug has a tendency to ionize at the pH of the intestinal lumen or the blood, the ionized form will have difficulty passing through lipid plasma membranes. If the drug interacts with tran sporter proteins on the cell membrane, its uptake into the cell may be increased or decreased, depending on the direction in which the transporter moves the drug. For example, the P-glycoprotein in enterocytes limits the oral absorption of some cancer chemotherapeutic agents by exporting them back into the lumen of the GI tract. Similarly, it has been found that multidrug transporters such as P-glycoprotein (PGP) and members of the multidrug resistance-associated protein (MRP) family are over-expressed in capillary endothelial cells in epileptogenic brain tissue, and, by transporting anti-epileptic drugs out, these proteins may be responsible for the pharmacoresistance of the epileptic brain to anti-epileptic drugs (LÃ ¶scher and Potschka, 2002). ... transporters such as P-glycoprotein (PGP) and members of the multidrug resistance-associated protein (MRP) family are over-expressed in capillary endothelial cells in epileptogenic brain tissue, and, by transporting anti-epileptic drugs out, these proteins may be responsible for the pharmacoresistance of the epileptic brain to anti-epileptic drugs (Loscher and Potschka, 2002). If a drug is capable of binding to plasma proteins such as albumin, then some of the drug molecules in the bloodstream bind to the proteins, while the remaining unbound drug molecules are available to reach equilibrium across all membranes and reach the target receptor. Thus, plasma protein binding limits the concentration of the drug at its site of action. When the site of action of concern is the brain, the capability of the drug to cross the blood-brain barrier determines the concentration of administered drug that can reach the target. The more lipophilic the drug in its unbound, non-ionized form, the great er will be its ability to pass through the endothelial cells forming the blood-brain barrier, and thus the higher will be its bioavailability in the brain. How the route of administration affects the fraction of the drug dose that reaches the target is also important. The most common route of administration is oral, however, this route has several implications on bioavailability, and the dose swallowed will not entirely reach the target site. Only a fraction of the ingested drug is absorbed from the intestine, depending on the factors discussed in the previous paragraph. As more absorption takes place in the intestine than the stomach, any factor that increases stomach emptying (such as such as lying down on the right side and level of physical activity) increases drug absorption as the
