Abstract: Liver fibrosis is the final common pathway of chronic liver diseases, having cirrhosis as a possible progression, which has liver transplantation as the only effective treatment. Human amniotic membrane represents a potential strategy as a therapy for liver fibrosis, due to its anti-inflammatory, anti-fibrotic and immunomodulatory properties. The aim of this study was to evaluate amniotic membrane effects as a treatment for hepatic fibrosis induced in rats by bile duct ligation (BDL), verifying alterations between two different forms of amniotic membrane application, around all the lobes of the liver and around only one lobe of the liver. Two weeks after inducing fibrosis, an amniotic membrane fragment was applied to the surface of the liver,... |

ABSTRACT: The objective of this research was to evaluate the clinical and microscopic effects in rabbits of lamellar keratoplasty using allogeneic omentum associated with canine amniotic membrane (AM). Rabbits were divided into two groups: one received the allogeneic free omental graft covered with the AM (OM-graft group), while the other received the AM graft containing omental mesenchymal cells (OM-cell group). Clinical signs were evaluated on different postoperative days. After the clinical assessments, the rabbits were euthanized and their corneas were obtained for histopathology and immunohistochemistry (Ki-67, marker for proliferation). Both groups showed chemosis, blepharospasm, eye discharge, hyperemia, and corneal opacity/edema. Neovascularization... |

Liver fibrosis is the most common outcome of chronic liver diseases, and its progression to cirrhosis can only be effectively treated with liver transplantation. The amniotic membrane (AM) has been studied as an alternative therapy for fibrosis diseases mainly for its favorable properties, including anti-inflammatory, anti-scaring and immunomodulatory properties. It was recently demonstrated that the AM reduces the progression of biliary fibrosis to its advanced stage, cirrhosis, when applied on the liver for 6 weeks after fibrosis induction. Here, we investigated the effects of AM on rat fibrotic liver, during a prolonged period of time. Fibrosis was induced by bile duct ligation (BDL), and at the same time, a fragment of AM was applied around the liver.... |

We present an ultrastructural study of the utilization of human amniotic membrane in the treatment of congenital absence of the vagina in 10 patients. All patients were surgically treated with application of an amniotic membrane graft using the modified McIndoe and Bannister technique. Sixty days after surgery, samples of the vaginal neo-epithelium were collected for transmission electron microscopy analysis. The ultrastructural findings consisted of a lining of mature squamous epithelium indicating the occurrence of metaplasia of the amniotic epithelium into the vaginal epithelium. The cells were arranged in layers as in the normal vaginal epithelium, i.e., superficial, intermediate and deep layers. There were desmosomes and cytoplasmic intermediate... |
