We report a case of a goblet-cell carcinoid tumor of the appendix which metastasized to the peritoneum and was treated by using cytoreductive surgery (CRS) with intraperitoneal chemotherapy. A 47-year-old male presented with chronic constipation and was diagnosed as having a rectal adenocarcinoma with a signet-ring-cell component under colonoscopy. Computed tomography suggested peritoneal metas...
We investigate the effects of perfusion with electrolyte solution on secretion of mucus by the frog palatine mucosa. The amount of mucus secreted was determined by measuring the contents of hexosamine in the mucus. Ciliary movement was examined by the particle transport method. The goblet cells, which secret mucus in the ciliated epithelium, were examined under light and electron microscopes af...
Infants with intrauterine growth restriction (IUGR) are at increased risk for neonatal and lifelong morbidities affecting multiple organ systems including the intestinal tract. The underlying mechanisms for the risk to the intestine remain poorly understood. In this study, we tested the hypothesis that IUGR affects the development of goblet and Paneth cell lineages, thus compromising the innate...
Goblet cell carcinoid tumors (GCCT) are uncommon neoplasms that predominantly occur in the vermiform appendix. They tend to occur in middle-aged adults with a near equal sex distribution. Most Goblet cell carcinoid tumors are discovered in appendices removed for acute appendicitis and for other reasons. Goblet cell carcinoid tumors demonstrate features of both classic carcinoid tumor and adenoc...
A clinicopathological correlation was performed on 24 patients suffering from keratoconjunctivitis sicca (KCS). Examination of conjunctival biopsies by light and transmission electron microscopy revealed stratification of the conjunctival epithelium with separation of the superficial cell layers, and this was directly proportional to the clinical severity of the disease. Counts of goblet cells ...
PURPOSE Mucins released into the tear film are crucial to maintaining a healthy ocular surface. Alterations in goblet cell numbers and mucin secretion are observed in chronic ocular surface inflammatory diseases. Nerve growth factor (NGF) plays a crucial role in healing and inflammation of the ocular surface. The aim of this study was to evaluate in vitro the effect of NGF on conjunctival goble...
Enterohemorrhagic Escherichia coli and related food and waterborne pathogens pose significant threats to human health. These attaching/effacing microbes infect the apical surface of intestinal epithelial cells (IEC), causing severe diarrheal disease. Colonizing the intestinal luminal surface helps segregate these microbes from most host inflammatory responses. Based on studies using Citrobacter...
This report describes a case of refractory enteropathy with circulating intestinal goblet cell autoantibodies (IGA). A 19 year old man with hyperthyroidism had suffered from protracted diarrhoea for nearly 10 years. Histological examination showed evidence of collagenous enterocolitis. The diarrhoea did not improve despite fasting under total parenteral nutrition. An immunofluorescence assay de...
