Display Subpage title and Content

Hi

<?php
	$pages = get_pages('child_of='.$post->ID.'&sort_column=post_id&sort_order=desc&parent='.$post->ID);
	foreach($pages as $page) {
?>

		<div class="section" id="<?php echo $page->post_name; ?>">
			<h4><a href="<?php echo get_page_link($page->ID) ?>"><?php echo $page->post_title ?></a></h4>
            <?php echo substr(apply_filters('the_content', $page->post_content),0,110).'....'; ?>
		</div>

<?php } ?>

this code is working on main page if the page has sub page. But i want even on subpage the content same level subpages will be displayed.
