Abstract

In this study, we have tried to demonstrate the effects of coating style used in oxygenators on various hematologic and clinical parameters. Twenty-seven patients were included in the study, who had undergone operations because of elective coronary artery disease. Albumin-coated oxygenator was used in Group I. In Group II, a synthetic polypeptide-coated oxygenator was used. C1-inhib (complement), C3c, C4, interleukins (IL-1β, IL2, IL-6, IL-10), and tumor necrosis factor alpha (TNF-α) levels were examined at four different time intervals. Hemoglobin, hematocrit, leukocyte and platelet counts, drainage, and transfused blood volumes were analyzed. Albumin levels were significantly lower in Group I than those in Group II 5 minutes after the removal of the cross-clamp. Twenty-four hours after the surgery, Group I patients also had a significantly higher white blood cell count compared to Group II patients. TNF-α levels in Group I were always expressed in considerably higher amounts than those in Group II. IL-6 levels were significantly higher in Group I, but IL-10 levels were observed to be higher in Group II (p < 0.05). Synthetic polypeptide-coated advanced technology, which employed oxygenators, had an important attenuator effect on acute phase reactants and also on the inflammatory response.

Abstract

The present article is about the presence of the tv in the society, in general, and its potential as an important agent, such as the family and the school, on the children’s and young people’s development and education. Nowadays we live in a complex world of images with sound, the most of them transmitted by the tv, the cinema and the internet. The infantile universe is full of those images. This way we structured this article in four parts, refering some of the contents related with this subject. The first part describes the presence of the television in the children's daylife and their relationship with the magic box, even the identification that they make with its favourites characters, in order to understand the space that the TV occupies in their lives. The second part presents the different messages transmitted by the television. It is important to analyze the main risks and advantages of television, that is to say, in spite of some programs show bad values, foment the excessive consumption, expose the children to an atmosphere of violence and pornography, also entertains, accompanies, educates, informs, favours the access to the culture and allows to unite the family around a program. At last the third part, this one outlines the necessity to put the tele as a curricular resource in the school, to teaches the students how to analyze, how to criticize and to think about the texts and the news of the world today. The television, considered a powerful tool, is decisive in the communication, such in the formation of values and ideas as in the culture transmission. The function of the school is not to remain far from this factor, but to try to meditate, to understand and to decide its impact, in a better way, on the development of the children and youngs. As conclusion we can add that we’ve tried to aim some strategies that educators and parents will be able to work, united to the children and the youngs, so they could have a new look of the Tv’s world and that they could know how to make their own selection and how to have a critical attitude before the watched product.
