AIM In the light of interest being shown in amniotic membrane grafts for use in ocular surgery, this study aims to identify the bacterial contaminants commonly found on placental membranes from both caesarean and vaginal deliveries. METHODS Samples of placental membrane were taken following both elective caesarean and normal vaginal deliveries. Bacterial contaminants were identified. RESULT...

overdose of acetaminophen causes severe hepatic necrosis in humans and experimental animals. studies on its hepatotoxicity remain a very active area since some of current data are still uncertain. in this study, freshly isolated rat hepatocytes were used to determine the effects of garlic extract and its component, allicin on the acetaminophen-induced cell cytotoxicity and to compare with the e...

BACKGROUND Stevens-Johnson syndrome is often associated with blinding ocular surface cicatricial sequelae. Recent reports have described markedly improved clinical outcomes with the application of amniotic membrane to the ocular surface during the acute phase. Here we describe the clinical outcome of a patient with acute Stevens-Johnson syndrome and severe ocular surface involvement in whom the...

A lot of pathological conditions could provoke damaging of the innervations of the cornea and lead to persistent epithelial defect (PED). AMX is lyophilized preparation of amniotic membrane (AM), which contains biological components and efficacy of AM for treatment of the corneal surface defects. In processing all the substances essential for biological effects of AM are preserved (growth facto...

Human amniotic membrane proved to be a versatile and useful temporary biologic dressing in studies involving 120 patients. Wounds, both traumatic and nontraumatic in origin, responded to a protocol that allowed coverage of tissues as diverse as exposed bowel, pleura, pericardium, blood vessels, tendon, nerve and bone. Wounds unresponsive to usual therapeutic measures responded to membrane appli...

We have investigated the effects of the intra-operative application of a combination of hyaluronic acid and amniotic membrane on adhesions in the flexor tendons of a chicken model. We used 144 tendons which were partially divided and then repaired by a modified Kessler technique. There were four test groups: group 1, simple tendon repair, group 2, repair site wrapped with amniotic membrane, gro...

BACKGROUND Conjunctival mucosa-associated lymphoid tissue (MALT) lymphoma is a rare, low-grade, non-Hodgkin's B-cell lymphoma. Herein, we report our successful management of the large conjunctival defect caused by resection of conjunctival MALT lymphoma by covering it with transplanted amniotic membrane. CASE A 28-year-old Japanese man, who had been diagnosed histologically as having conjunct...

INTRODUCTION Approximately 1% of the general population have venous or arterial lower limb ulcers. These lesions can be treated with biological skin substitutes such as cadaver skin or tissue-engineered skin equivalents, but treatment fails in 25% of cases, resulting in pain and loss of patient autonomy, as well as increased morbidity and health care costs. In the treatment of corneal ulcers, a...

Objective: to evaluate the efficacy of the amniotic membrane used with polypropylene mesh against the formation of adhesions and its influence on healing. Methods: twenty five female Wistar rats were anesthetized for creating a parietal defect in the anterior abdominal wall. Its correction was made with polypropylene mesh alone and associated with amniotic membrane. In the control group (n=11),...

Bone marrow derived progenitor cells were reported to be involved in the pathogenesis of pterygium and have been suggested to be important in angiogenesis and the repair process after tissue damage. In order to investigate the involvement of these cells in wound healing after a pterygium excision, immunohistochemical staining was performed with a temporary amniotic membrane, applied to the bare...
