background and aim: urinary tract infections (uti) are common cause of morbidity and mortality especially in young children around the world. pyelonephritis can lead to scar formation, and subsequent hypertension and renal failure. interleukins play a major role in renal scar formation following febrile pyelonephritis. the aim of this study was to investigate the level of urinary interleukin-6 ...

Glial scar is formed following surgical damage to the cerebral cortex. In the present study we examined the ultrastructural status of the cerebral cortex 14 to 180 days following surgical damage to cerebral parenchyma. The results showed a contribution of astrocytes, but also mesodermal cells, to the process of scar formation. Furthermore, our study showed that the process initiated by trauma d...

This study aimed to use a mouse model of hypertrophic scarring by mechanical loading on the dorsum of mice to determine whether the nervous system of the skin and inflammation participates in hypertrophic scarring. Results of hematoxylin-eosin and immunohistochemical staining demonstrated that inflammation contributed to the formation of a hypertrophic scar and increased the nerve density in sc...

The repair process after CNS injury shows a well-organized cascade of three distinct stages: inflammation, new tissue formation, and remodeling. In the new tissue formation stage, various cells migrate and form the fibrotic scar surrounding the lesion site. The fibrotic scar is known as an obstacle for axonal regeneration in the remodeling stage. However, the role of the fibrotic scar in the ne...

- healing of surgical wounds and their complications such as infection or scar formation are of major concern in surgery. tissue glues are advanced to reduce these problems. in a prospective study, we have evaluated surgical wound healing in 76 patients whose surgical wounds were repaired by tissue glues (histoacryl). this study was performed in four leaching hospitals (sina, shariaty, shohada,...

Injury to the CNS leads to formation of scar tissue, which is important in sealing the lesion and inhibiting axon regeneration. The fibrotic scar that comprises a dense extracellular matrix is thought to originate from meningeal cells surrounding the CNS. However, using transgenic mice, we demonstrate that perivascular collagen1α1 cells are the main source of the cellular composition of the fib...

Laparoscopic cholecystectomy is the preferred treatment for symptomatic cholelithiasis. Severe local inflammation and scar formation are commonly responsible for conversion to open surgery. Fibrosuppressive effects of estrogen on peritoneal inflammatory conditions could provide low, dense fibrosis or scar formation around the gallbladder and make laparoscopic cholecystectomy easier in women and...

BACKGROUND A hypertrophic scar is a unique fibrotic disease that only exists in humans. Despite advances in burn care and rehabilitation, as well as progress in the management during these decades, the hypertrophic scar remains hard to cure following surgical methods and drugs for treatment. In this study, we are looking forward to finding the multitude of possible traumatic mechanisms and the ...
