[Expression and clinical significance of Cox-2 and XIAP in malignant tumors of the salivary gland].

Purpose: To detect the expression of Cox-2 and XIAP in adenoid cystic carcinoma (ACC) and mucoepidermoid carcinoma (MEC) of salivary glands. To study the role and correlation between the expression of Cox-2 and XIAP in malignant tumors of salivary gland.

Methods: Immunohistochemical SP staining method was used to quantify the protein expression levels of Cox-2 and XIAP in 95 patients with malignant tumors of the salivary gland (50 ACCs,45 MECs),10 patients with pleomorphic adenoma and 10 persons with normal salivary gland tissues.

[The isolation and identification of bone marrow mesenchymal stem cells derived from rabbit mandible].

Purpose: To investigate the methods of isolation, culture and identification of BMMSCs derived from rabbit mandible.

Methods: BMMSCs were collected from rabbit mandible and isolated by density gradient centrifugation. Cells were adherently cultured in vitro, and P2 or P3 BMMSCs populations were collected and examined.
