13. Predictive factors and prognostic importance of limph node metastasis in salivary gland carcionomas / Fatores preditivos e importancia prognostica das metastases linfonodais em carcinomas das glandulas salivares
Benign and malignant salivary gland neoplasias comprises 4?10% of all the neoplasias affecting humans. The parotid glands are the most commonly affected, followed by minor salivary and submandibular glands. Regional metastasis, tumor extension, presence of pain, and age older than 55 years have been considered poor prognostic indicators. The aim of this stud

14. Carcinoma mucoepidermóide de glândulas salivares:: características clinicopatológicas e imunoexpressão de c-erbB-2
Salivary glands tumors are rare and morphologically diversified, so, there are few papers about only one histologic type. Mucoepidermoid carcinoma (MEC) is the most common malignant neoplasm of major and minor salivary glands. The histological appearance of MEC is diversified and is correlated with the biological behavior of the tumor. Oncogene c-erbB-2 pres

15. Estudo do envolvimento das glandulas salivares maiores nos pacientes submetidos ao transplante alogenico de celulas progenitoras hematopoeticas, atraves de cintilografia
Salivary gland dysfunction is a common sequel of the hematopoetic progenitor cell transplantation (HPCT) and salivary secretion substantially reduce during conditioning regimen. A gradual flow rate reconstitution could be detected few days after the HPCT. Major salivary glands play a difficult role to diagnosis. Nuclear medicine is a well-documented method a

16. Expressão imuno-histoquímica das integrinas a2ß1, a3ß1 e a5ß1 em adenoma pleomórfico de glândula salivar menor e maior e carcinoma adenóide cístico / Immunohistochemical expression of D2E1, D3E1 e D5E1 integrins in pleomorphic adenoma from minor and major salivary glands and adenoid cystic carcinoma
Pleomorphic adenoma and adenoid cystic carcinoma (ACC) consist benign and malignant neoplasm from salivary gland, respectively. These neoplasms share some characteristics, such as cellular origin and considerable production of extracellular matrix, however, with distinct biological behavior. The aim of the present study was to compare the expression of D2E1,

17. Purification and characterization of β-1,3-glucanases from insects / Purificação e caracterização de β-1,3-glucanases de insetos
P. americana salivary glands and T. molitor midgut epithelium actively secrete laminarinases into the midgut. The major laminarinases from P. americana (LIQ1, 42kDa and LAM_P, 45kDa), A. flavolineata (LAM_A, 45kDa) and T molitor (LAM_T, 50kDa) were purified until homogeneity. These enzymes have different specificities, action patterns and activesite catalyti

18. Avaliação clinica, histologica e imunoistoquimica de GVHDc em glandulas salivares menores
The major cause of morbidity and mortality in patients undergoing allogeneic bone marrow transplantation is graft-versus-host disease (GVHD). The clinical and histological manifestation of oral mucosa can precede other organ involvement in the GVHDc. The aim of our study was to evaluate the predictive risk factors to GVHDc, the histological and immunohistoch

19. Efeito de ions metalicos divalentes sobre a atividade de metaloproteases da matriz secretadas por celulas do tecido gengival
Matrix Metalloproteinases (MMPs) are a family of proteolytic enzymes that mediates the degradation of extracellular matrix. They are secreted as inactive proenzymes (zymogen), and they are thought to be activated in the tissue by cleavage of the propeptide. All members of this family have zinc and calcium binding to the active site. The MMPs take part in phy

20. A glandula parotida na AIDS : analise de 100 casos de autopsia / Autopsy findings in the parotid glands of 100 Brazilian patients with aids
This study describes the alterations found in the parotid glands of 100 patients who died of AIDS and of 15 who died for other reasons. Sialadenitis occurred in the parotid of 13,34% cases of the control group, and in 35% cases of the AIDS group. Ten cases of mycobacteriosis, three of cryptococosis, two of histoplasmosis, nine of citomegalovirusis, six lymph

21. Estudo da histopatologia das glandulas salivares maiores de 32 pacientes aideticos autopsiados / Autopsy findings in the major sallvary glands of 32 Brazilian patients with aids
This study describes the alterations found in the major salivary glands of 32 patients who died of AIDS and of 13 who died for other reasons. Sialadenitis occurred in the parotid of 23% cases of the control group, and in 54%, 51 % and 45% cases of the parotid, submandibular and sublingual glands respectively, of the patients with human immunodeficiency virus

22. Candidose experimental e recuperação de Candida albicans na cavidade bucal de camundongos normais e xerostomicos
The presence of Candida albicans and candidosis development in the oral cavity of normal and sialoadenectomized mice were evaluated after one and four inoculations, with 108 viable cells of C. albicans in the mouth of the animals. The xerostomia was obtained by surgical removal of the major salivary glands from mice (sialoadenectomy) and the recovery of the

23. Efeitos da sialoadenectomia na presença de Candida albicans e candidose na cavidade bucal de ratos
On this work it was studied the effects of xerostomia, provoked by extirpation of the major salivary glands, on the carriage of Candida albicans and development of candidosis in the mouth of rats. Candida gender was isolated from 65 (17,06%) of 381 Wistar rats, and of these isolates, 20% were characterized as C. albicans species... Note:The complete abstract

24. Electron microscopic detection of statherin in secretory granules of human major salivary glands
In order to increase current knowledge regarding statherin secretion into the oral cavity, ultrastructural localization of this peptide was investigated in human salivary glands by using a post-embedding immunogold staining technique. Statherin reactivity was found inside the granules of serous cells of parotid and submandibular glands. In parotid granules i
