Hydrophilic polymer coatings were designed to reduce friction between the catheter and vessel wall and facilitate intravascular manipulations during catheterization and placement of drug‐eluting stents. One newly reported complication of such hydrophilic coatings is the fragmentation and embolization of the polymer, which can lead to ischemia and infarct by blocking the small vasculature. In this report, we present a patient with a non‐healing ulcer on the leg. Biopsy from the ulcer revealed the presence of hydrophilic polymer emboli within the dermal vessels. This is one of the few reports of such a complication involving the skin. Our objective is to emphasize the histopathologic features of this uncommon iatrogenic phenomenon. 相似文献

Objective
To evaluated the differential effects of ethanol extraction of Citrullus colocynthis (C. colocynthis) on the blood glucose concentration and pathology of pancreas, liver, lungs, kidney and gastrointestinal tract in the alloxan induced diabetes in rats.Methods
Diabetes mellitus was induced in 20 adult female Albino rats, using intraperitoneal injection of 120 mg/kg alloxan. The diabetic rats were randomly assigned into two equal groups. The first group was treated with the extract of C. colocynthis seed (300 mg/kg) and the rats of the second group, as an untreated diabetic group, received ordinary diet. Ten non diabetic rats remained as a normal control group.Results
The results of this study indicate that C. colocynthis was able to reduce blood glucose significantly compared with the control diabetic group (P<0.05). Histopathologically, alloxan resulted in severe necrotic changes in the pancreatic islets, especially in the central area of the islets. Tissue sections of the pancreas in the treated rats demonstrated enhanced regeneration of B cells and increased size of pancreatic islets. Liver of the treated diabetic rats revealed significant improvement of the hepatic tissue compared to those of the untreated diabetic rats.Conclusions
The present study indicated a significant anti-hyperglycemic effect of C. colocynthis seed and supported its traditional usage in treatment of diabetes mellitus. 相似文献7.
The current treatment philosophy is to prevent and detect dental disease at the earliest stage in order to avoid invasive treatment. With the current understanding of the nature of dental disease and its process, the treatment philosophy is now changing to a more conservative approach and the concept of minimal intervention is gaining popularity in modern dentistry throughout the world. It is now established that demineralized but non-cavitated enamel and dentine can be healed and traditional surgical approach of drilling and filling may no longer be necessary as this only treats the symptoms of the disease and not the cause. However, when surgical intervention is indicated, the least invasive techniques such as preventive resin restoration and minimal cavity preparation are utilized. The aim of this article is to give dental professionals an overview of the concepts of minimal intervention dentistry and recent innovations in dental technology in both the diagnosis and treatment of dental caries. 相似文献
