Photodynamic therapy uses nonthermal coherent light delivered via fiber optic cable to locally activate a photosensitive chemotherapeutic agent that ablates tumor tissue. Owing to the limitations of light penetration, it is unknown whether photodynamic therapy can treat large osseous tumors. We determined whether photodynamic therapy can induce necrosis in large osseous tumors, and if so, to qu...

PURPOSE A retrospective investigation of the clinical and radiologic features as well as the bronchoscopic appearance was carried out in patients with endobronchial aspergilloma. MATERIALS AND METHODS Ten patients with endobronchial aspergilloma diagnosed by bronchoscopy and histological examination were identified at the Gyeongsang University Hospital of Korea, from May 2003 to May 2009. R...

Necrotic enteritis has until recently been considered an infections disease of swine caused by the micro-organism Salmonella eholeraesuis. Lately, however, the relation of swine nutrition to the development of this disease has been given prominent attention. The results of investigations now in progress in different sections of the country may clarify the question of the cause of the disease. N...

Studies from this laboratory have shown that the border of a 24-hour canine infarct is histologically sharp and is composed of numerous interdigitating peninsulas of necrotic and normal tissue. To see if this sharp boundary is spatially related to the capillary beds of occluded and non-occluded arteries, the left anterior descending artery (LAD) was ligated in five mongrel dogs. Twenty-four hou...

The paucity of mammalian adult cardiac myocytes (CM) proliferation following myocardial infarction (MI) and the remodeling of the necrotic tissue that ensues, result in non-regenerative repair. In contrast, zebrafish (ZF) can regenerate after an apical resection or cryoinjury of the heart. There is considerable interest in models where regeneration proceeds in the presence of necrotic tissue. W...

1. The fall in chlorine concentration of Dakin's hypochlorite solution is more rapid in contact with necrotic than in contact with normal tissue. 2. The fall in chlorine concentration of chloramine-T solution is very slight when applied to necrotic tissue and is negligible when applied to normal tissue. 3. The action of the hypochlorite solution on tissue results in the separation of particles ...

Prostate gland is an accessory of the male reproductive system.Prostate begins development from mesenchymal tissue, surrounding urogenital sinus in 3 rd month gestation. Epithelial buds invaginate posterior on either side verumontanum. Concurrently, Wolffian ducts develop into seminal vesicles, epididymis, Vasdeferens and ejaculatory that are stimulated by fetal testosterone. Histologically all...

Skin biopsy 1 Always inject a large volume of local anaesthetic into the area to be biopsied. The more rapid the better, as this really distorts the tissue planes making microscopic evaluation a real challenge. 2 Always biopsy the centre of any ulcer as this will guarantee that the pathologist will not be able to differentiate between a benign or malignant process as he enjoys the vista of necr...

background thermal injury is associated with several biochemical and histopathological alteration in tissue. analysis of these objective parameters in research and clinical field are common to determine healing rate of burn wound. negative pressure wound therapy has been achieved wide success in treating chronic wounds. this study determines superficial burn wound healing with intermittent nega...

The article presents the results of experimental modeling super­ficial fragment gunshot wounds soft tissues, obtained in low-energy wounds. pathomorphosis was studied, and features timing their healing were compared depending on temperature damaging fragments. aim work to study effect injuring shrapnel processes tissues animals with superficial Using random number method, laboratory (rabbits) d...
