Sera from 92 patients with adult coeliac disease, 20 patients with Crohn's disease, and 89 control patients were tested for the presence and immunoglobulin class of anticonnective tissue antibodies. In adult coeliac disease patients taking a normal diet there was a high frequency of sera positive for connective tissue antibodies and the majority were IgA in class. Following gluten withdrawal, I...

The aim of the present study was to evaluate the gingival connective tissue response to screw-type titanium implants coated with Type I collagen nanofibers, which were prepared using the electrospray deposition method. Implants were immediately inserted into the socket of maxillary first molars after the extraction. Undecalcified sections after 4 weeks implantation were histologically observed....

Evidence is presented that the proliferating gall bladder epithelium in the dog and guinea pig is capable of stimulating bone formation in certain connective tissues such as the abdominal wall. Other connective tissue areas such as the subepithelial connective tissue of the gall bladder and urinary bladder do not share in this tissue reaction and resist the bone stimulus of the epithelium. The ...

The chordae tendineae of the heart are collagenous strands which extend from the apical margin of papillary muscles of the heart to the various areas on the ventricular surface of the valve leaflets. They convey the contraction of the papillary muscles to the valve and so prevent the latter’s eversion. Eight hearts of the ostrich were collected, opened the left side of the heart and the length ...

Introduction: Cigarette smoking has been recognized to be a risk factor for progression of periodontal disease . Due to less inflammation and bleeding in the presence of clinical signs of periodontal disease in smokers than in nonsmokers and given the conflicting results of studies on changes in the epithelium and gingival connective tissue by smoking, this study was performed to evaluate the t...
