Therapeutic angiogenesis is a promising approach to treat ischemic skin flaps. We delivered basic fibroblast growth factor (bFGF) to the recipient bed of a rat dorsal skin flap by a drug delivery system with acidic gelatin hydrogel microspheres (AGHMs), and assessed augmentation of neovascularization and flap viability. An axial skin flap was elevated on the back of male Sprague–Dawley rats, and bFGF solution or bFGF-impregnated AGHMs were injected into the recipient bed. The dose of bFGF in the bFGF solution was set to 15 (Sol-15 group), 50 (Sol-50 group), or 150 μg (Sol-150 group). Correspondingly, 2 mg AGHMs were impregnated with 15 (AGHM-15 group), 50 (AGHM-50 group), or 150 μg (AGHM-150 group) bFGF. Other groups of animals received phosphate-buffered saline (Sol-Cont group) or phosphate-buffered saline-impregnated AGHMs (AGHM-Cont group) as controls. Seven days later, analyses of the area of necrosis, microangiographic findings, and histological findings in the flap were carried out. The area of necrosis in the AGHM-150 group was significantly smaller than that in the other groups. Microangiographic and histological analyses showed that neovascularization of the ischemic skin flap significantly increased in the AGHM-150 group as compared with the Sol-150 group and the AGHM-Cont group. These findings suggest that continuous delivery of bFGF to the recipient bed by bFGF-impregnated AGHMs enhances the viability of an ischemic skin flap. 相似文献

Whether the pathogenesis of polymorphic reticulosis is from T cells, B cells, or histiocytes has been controversial. In this study, the Southern blot hybridization technique was used to analyze immunoglobulin and T-cell receptor β-chain genes and to perform the conventional surface marker analysis in two patients with polymorphic reticulosis. The immunophenotype demonstrated the presence of predominantly mature, activated T-lymphocytes, minimal B-cells, and no natural killer cells or monocytes/granulocytes. The mature T-cell phenotype could be due to either inflammatory infiltrates or neoplastic cells of peripheral T-cell type, because the two coexist in polymorphic reticulosis tumors. The value of surface marker examination is limited in the analysis of PMR tumors. However, genetic analysis revealed that only Ig genes were rearranged, with no rearrangement of the TCRβ gene. Rearrangement of immunoglobulin genes occurs in B-lineage lymphoid neoplasms and is thought to be a criterion for diagnosis of lymphoid neoplasms. Based on genetic analysis and clinicopathologic information, this study concluded that polymorphic reticulosis is a malignant lymphoma of B-cell lineage. 相似文献

In a consumer-oriented National Health Service, quality control (clinical audit) is of increasing importance. Managers must be able to demonstrate both the efficiency and quality of their services when preparing business plans.This paper reports on a project to set, test, and quantify standards for clinical intervention.Since this type of work is in its infancy in paramedical services, a problem-solving approach was adopted. All staff helped in standard-setting and participated in testing.The audit was concerned with the process of intervention since outcome is extremely variable when dealing with chronic disorders involving multiple disabilities.The results were encouraging, demonstrating that the method was successful in quantifying the quality of intervention and had potential as a management tool for monitoring individual staff performance by indicating areas requiring additional support or training.It linked with the existing appraisal system by offering quantified targets for performance, and proved motivating to staff and consumers.The information gained may be useful in marketing the service. 相似文献

Chickenpox and shingles (varicella‐zoster virus [VZV]) pose a threat to individuals who are immunosuppressed and/or have rheumatoid arthritis or another inflammatory musculoskeletal condition. In this paper we present a literature review of the condition, management and prevention. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献
