Several transplantaDitmouse and rat tumors were injured in a reproducible manner by implanting a length of cotton thread in their substance. Normal tissues, including liver, spleen, kidney, and subcutaneous connective tissue, were treated similarly. At the end of 1 week tissues containing thread were removed for histologie study. Consistent ly, the inflammatory response to the foreign body with...

Calcium phosphate cement (CPC) consisting of Ca4 (PO4)2O and CaHPO4 (2H2O) was recently developed. This study evaluated in vivo aspects of CPC and CPC mixtures compared to those of commercial hydroxyapatite (HP) and several endodontic materials: Grossman's cement (GC), calcium hydroxide-iodine paste (CHP) and gutta-percha plate (GP). Biocompatibility of subcutaneous implants in Donryu rats was ...

INTRODUCTION The purpose of this study was to compare the histocompatibility of white (WMTA) and gray (GMTA) mineral trioxide aggregate mixed with 0.12% chlorhexidine (CHX) and distilled water (DW) in subcutaneous connective tissues of rats. MATERIALS AND METHODS The freshly mixed WMTA and GMTA with CHX or DW were inserted in polyethylene tubes and implanted into dorsal subcutaneous connectiv...

A great deal af the current interest in the connective tissues has been focused on the extracellular components of these tissues, particularly collagen and the mucopolysaccharides. Alterations in the amounts and in the physical and chemical properties of these extracellular components have been implicated as contributing factors in many abnormal and diseased states such as rheumatoid arthritis,...

The results of the autopsy of a 38-year-old female with mixed connective tissue disease who had suffered from painful subcutaneous calcification in her buttocks and extremities for 14 years and died from rapidly progressive pulmonary hypertension are reported. On autopsy, her heart and lungs revealed changes of severe pulmonary hypertension with intimal thickening and plexiform lesions in the s...

Hydatid disease, caused by larval stage of Echinococcus granulosus, is a common parasitic infection of human and animal. Although liver and lung are the most commonly affected area, hydatid cyst may develop any part of the body. Primary subcutaneous hydatid cyst is extremely rare. We report a case of 54 years old man who presented with palpable mass in scapular region from 3 years ago....

Loose” connective tissue forms a network extending throughout the body including subcutaneous and interstitial connective tissues. The existence of a cellular network of fibroblasts within loose connective tissue may have considerable significance as it may support yet unknown body-wide cellular signaling systems. We used a combination of histochemistry, immunohistochemistry, confocal scanning ...
