25. Polymeric microcapsules poduction from sodium alginic acid for cell therapy
Development of polymeric materials has been increasingly emphasized in Biomedicine. Here, we evaluate the use of microcapsules made of Biodritin®, a biocompatible polymer compound which contains sodium alginic acid, a natural polymer extracted from algae, and Cis-Chondroitin sulfate, a glycosaminoglycan from the extracellular matrix. Gelation of this polyme

26. Influência do sulfato de condroitina na formação de filmes isolados de polimetacrilato: avaliação do índice de intumescimento e permeabilidade ao vapor d'água
Natural or modified chondroitin sulfate was incorporated in to polymethacrylate to obtain isolated films. The addition of polysaccharide to synthetic polymers occurred at different rates. Isolated films were micro and macroscopically characterized and swelling index and water vapor transmission were determined. Results indicated changed transparency and flex

27. Experimental osteoarthritis in rats: evaluation of antinociceptive and chondroprotective effects of glucosamine sulfate and chondroitin sulfate / Osteoartrite experimental em ratos: efeito de sulfato de glicosamina e sulfato de condroitina sobre a incapacitação articular e a lesão de cartilagem articular
OBJETIVOS: Avaliar o efeito de sulfato de glicosamina e sulfato de condroitina sobre a nocicepção e o dano da cartilagem articular em um modelo de osteoartrite experimental em ratos. MÉTODOS: Osteoartrite (OA) foi induzida em ratos Wistar machos por transecção do ligamento cruzado anterior (TLCA) do joelho direito. Um grupo falso-operado (SHAM) foi util

28. Terapia laser de baixa potência (904nm) associada ao sulfato de condroitina e quitosana na reparação de defeito osteocondral experimental da cabeça do úmero de cães. Estudo histopatológico / Low laser therapy (904nm) associated with chondroitin sulfate and chitosan on the articular reparation after osteochondral experimental defect on dogs humeral head. Histopathological study
This work was developed in order to evaluate microscoply the influence of gallium arsenate (Ga-As) diodo laser associated with chondroitin sulfate and chitosan on the healing process of the articular surface of the humeral head of dogs following experimental osteochondroplasty. Sixteen adult dogs were randomly allocated into four groups of four animals. All

29. Distribution of small proteoglycans and glycosaminoglycans in humerus-related articular cartilage of chickens
The expression of components present in the cartilaginous extracellular matrix is related to development, gender, and genotype, as well as to the biomechanical properties of each type of cartilage. In the present study, we analyzed small proteoglycans and glycosaminoglycans present in different cartilages of the chicken wing after extraction with guanidine h

30. Avaliação "in vitro" dos processos de proliferação e diferenciação de celulas osteoblasticas e a mineralização sobre matrizes anionicas de colageno para reparo osseo
Collagen has been extensively described as an important material in bone tissue engineering due to its biocompatibility, biodegradability, low antigenicity, and high tensile strength. However, collagen scaffolds in their pure form have some drawbacks and improvements in its physical, chemical and biological properties are necessary to overcome those inadequa

31. Cartilagem articular de avestruz : um estudo estrutural e bioquimico
The articular cartilage is a hyaline connective tissue that contains cells and a great amount of extracellular matrix, which is composed of collagen, non-collagenous glycoproteins, and proteoglycans. This work aimed to describe the composition and organization of the extracellular matrix from articular cartilage of ostrich, which is a big bird with commercia

32. Glycosaminoglycans affect the interaction of human plasma kallikrein with plasminogen, factor XII and inhibitors
Human plasma kallikrein, a serine proteinase, plays a key role in intrinsic blood clotting, in the kallikrein-kinin system, and in fibrinolysis. The proteolytic enzymes involved in these processes are usually controlled by specific inhibitors and may be influenced by several factors including glycosaminoglycans, as recently demonstrated by our group. The aim

33. Decorin is one of the proteoglycans expressed in Walker 256 rat mammary carcinoma
Proteoglycan and glycosaminoglycan content was analyzed in a model of rat mammary carcinoma to study the roles of these compounds in tumorigenesis. Hyaluronic acid and proteoglycans bearing chondroitin and/or dermatan sulfate chains were detected in solid tumors obtained after subcutaneous inoculation of Walker 256 rat carcinoma cells. About 10% of sulfated

34. Intestinal fibrovascular nodules caused by Schistosoma mansoni infection in Calomys callosus Rengger, 1830 (Rodentia: Cricetidae): a model of concomitant fibrosis and angiogenesis
Human schistosomiasis develops extensive and dense fibrosis in portal space, together with congested new blood vessels. This study demonstrates that Calomys callosus infected with Schistosoma mansoni also develops fibrovascular lesions, which are found in intestinal subserosa. Animals were percutaneously infected with 70 cercariae and necropsied at 42, 45, 5

35. Galactosaminoglycans from normal myometrium and leiomyoma
In many tumors, the amount of chondroitin sulfate in the extracellular matrix has been shown to be elevated when compared to the corresponding normal tissue. Nevertheless, the degree of chondroitin sulfate increase varies widely. In order to investigate a possible correlation between the amount of chondroitin sulfate and tumor size, several individual specim

36. Astroglial cells derived from lateral and medial midbrain sectors differ in their synthesis and secretion of sulfated glycosaminoglycans
Astroglial cells derived from lateral and medial midbrain sectors differ in their abilities to support neuritic growth of midbrain neurons in cocultures. These different properties of the two types of cells may be related to the composition of their extracellular matrix. We have studied the synthesis and secretion of sulfated glycosaminoglycans (GAGs) by the
