Primary intestinal lymphangiectasia presenting as limb convulsions: A case report.

Background: Primary intestinal lymphangiectasia (PIL) is a rare protein-losing enteropathy characterized by abnormally dilated lymphatic structures, resulting in leakage of lymph (rich in protein, lymphocytes, and fat) from the intestinal mucosal and submucosal layers and thus hypoproteinemia, lymphopenia, hypolipidemia, and pleural effusion.

Case Summary: A 19-year-old Chinese male patient complained of recurrent limb convulsions for the last 1 year. Laboratory investigations revealed low levels of calcium and magnesium along with hypoproteinemia and high parathyroid hormone levels, whereas gastroscopy exhibited chronic non-atrophic gastritis and duodenal lymphatic dilatation.

GLP-1 expression in von Ebner's gland of diabetic rats.

GLP-1, a peptidergic endocrine hormone, which associate with appetite control, glucose homeostasis and satiety. It might play an important role in the gustatory system. We tried to investigate the expression of GLP-1 in von Ebner's gland of diabetic and control rats, and the ultrastructure changes on von Ebner's gland of diabetes rats.

Expression of sulfonylurea receptors in rat taste buds.

To test the possibility that a fast-onset promoting agent repaglinide may initiate prandial insulin secretion through the mechanism of cephalic-phase insulin release, we explored the expression and distribution character of sulfonylurea receptors in rat taste buds. Twenty male Wistar rats aged 10 weeks old were killed after general anesthesia. The circumvallate papillae, fungiform papillae and pancreas tissues were separately collected.

Differential expression of connexin 43 in human autoimmune thyroid disease.

Gap junctions provide a pathway for cell-to-cell communication. Reduced thyroid epithelial cell-cell communication has been reported in some animal models of autoimmune thyroid disease. In order to assess whether this change was similar to human autoimmune thyroid disease, we identified some connexin proteins and their corresponding mRNA in human thyroid gland.

Expression of alpha-gustducin in the circumvallate papillae of taste buds of diabetic rats.

Taste impairment is a complication of Diabetes mellitus and some studies have shown this taste disorder in diabetes. Diabetes can decrease the ability of individuals to detect and recognize sweet, salty and bitter tastes. alpha-Gustducin is a transducin-like G-protein selectively expressed in 20 - 30% of taste receptor cells, which has been shown to be involved in bitter, sweet and umami taste responses.

Expression of glucagon-like peptide-1 in the taste buds of rat circumvallate papillae.

Glucagon-like peptide-1 (GLP-1), a 30-amino-acid peptide hormone, is a typical peptide of the brain-gut axis and can affect the metabolism of various tissues and organs. GLP-1 is secreted by intestinal L cells in response to nutrient ingestion. Some studies have shown that taste signaling elements were co-expressed in enteroendocrine cells of the small intestine, and in particular by L-cells.
