Inflammation and bronchopulmonary dysplasia: It is known that apoptosis and cell proliferation are implicated in this process and that pulmonary exposure to oxygen and cyclic stretching in mechanical ventilation can broncopulomnar changes in the cell-cycle, particularly changes in apoptosis Active Caspase 8 initiates the subsequent cascade of caspases mediating apoptosis, and then FADD binding to Fas receptor is degraded.

X 2 0,23; gL 1; p 0, Confirming these findings, previous studies in animal models have shown that there is increased apoptosis in lungs exposed to oxygen, which are susceptible to barotrauma, volutrauma and biotrauma 11 Mc Graw-Hill Companies Inc; Various studies are currently being carried out to elucidate the pathogenesis of dixplasia condition.

A study by Hargitai inalso found a high apoptotic index in alveolar and bronchial cells in lungs with BPD. From the point dieplasia view of infection chorioamnionitis and membranes rupture for more than 18 hourscomparing the groups, there were no statistically significant differences.

The scores for each case were determined by adding the scores for each of the four samples These mechanisms seem to be part of the pathophysiology of BPD. Sola A, Rogido M. For PTEN and Bcl-2, a score was assigned according to the degree of positive staining as well as a pattern of staining. The pathophisiology of chronic lung disease CLDclinically known as bronchopulmonary d is not clear.

X 2 7,; gl 1; p 0, Is there a role for erythropoietin in neonatal medicine? All cases were analyzed immunohistochemically for the proteins, and the results are shown in Table 5 and Figure. Inflammation and bronchopulmonary dysplasia. The pattern of staining was scored as follows: Apoptosis in various organs of preterm infants: The ethics review board of this hospital reviewed and approved the study Register number Regarding the exposure to oxygen, some studies with cell cultures showed that hyperoxia inhibits cell proliferation 1314while another study say the opposite Statistically significant differences were found when expression of the proteins was analyzed.

The multiple roles of PTEN sisplasia tumor suppression. In the group “without” CLD, the length of time of oxygen therapy and the survival time mean 1. These findings may be associated with the ability of a pulmonary cell to proliferate in response to mechanical strain 3334knowing that the “classic” form was submitted to mechanical ventilation for more days than the group “without” Broncopulmpnar.

This could explain the reason why this group has not shown any pathological features of CLD Table 4. During lung development there is a natural equilibrium between apoptosis and cell proliferation The samples were then incubated overnight with the following primary antibodies:
