Opis:
Atherosclerosis is an inflammatory disease characterised by the accumulation of lipids and their metabolites in the artery wall. During inflammation circulating LDL are taken up by macrophages through two major scavenger receptors: CD36 and scavenger receptor A (SRA). Fatty acids that are common in food, e.g. linoleic acid and n-3 unsaturated fatty acids can modulate expression of CD36 on the macrophage surface. Conjugated linoleic acid isomers (CLA) that originate from the human diet, have demonstrated antiatherogenic properties in several experiments. Animal study evidenced that CLA could induce resolution of plaque by activation of peroxisome proliferator activated receptors and down-regulation of pro-inflammatory genes. Less unequivocal results were obtained in human studies (on the CLA effects on the inflammatory process). Therefore in this study we investigated the influence of CLA on CD36 expression and lipid accumulation in human macrophages. Macrophages were incubated with 30 µM cis-9,trans-11 CLA, trans-10,cis-12 CLA or linoleic acid for 48 h. After that, expression of CD36 as well as accumulation of lipids were measured by flow cytometry, microscopy and a spectroscopic method. We demonstrate that both cis-9,trans-11 C 18:2 CLA and linoleic acid slightly elevated expression of CD36, whereas second isomer - trans-10,cis-12 CLA - did not. Nevertheless, only trans-10,cis-12 CLA triggered delipidation of macrophages, that is decreased triacylglycerols concentration. Also in human adipocytes, trans-10,cis-12 CLA causes cell delipidation by reduction of PPAR receptor expression. We propose a similar mechanism for human macrophages/foam cells.

Opis:
Health care of children and young people is part of a system of care of the so called “developmental age population.” In this system, prevention plays a key role. The aim of the study was, basing on the obtained results, to develop guidelines for the regional pro-family policy in care of a rural child. The study included children and young people of school age, from 14 to 19 years of age. Overall the analysis included 6,971 children and adolescents and 6,971 parents. Organization of health care of children and school adolescents depended on the solutions approved by individual founding bodies of Health Care Units and Regional Patients’ Funds. The withdrawal of nurses from school was observed. The tasks of prevention character performed previously by nurses employed at schools began to be implemented within the framework of primary health care in the child’s place of residence. For proper implementation of the tasks of school nurses and the proper development of school hygiene, it is important to establish a uniform and maximum number of pupils per one nurse, taking into account all circumstances, and to develop standards of care for the student, taking into account the age of the student, school type, and the region.
