Two anticancer agents, one lipophilic, 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU), and one hydrophilic, 5-(3,3-dimethyl-1-triazeno) imidazol-4-carboxamide (DTIC), were used to treat Brown-Pearce epithelioma in the anterior chamber of rabbit eyes. The BCNU test animals were divided into three groups: one treated by direct injection of the drug into the subconjuntival space or the anterior chamb...

  Peripheral calcifying cystic odontogenic tumor (PCCOT) is a rare odontogenic lesion, which represents about 1% of jaw cysts. Here we report clinicopathologic, radiographic and CT scan images of a new case of recurrent large PCCOT located in mandibular gingiva in a 77-year-old male with history of a nodular mass in the same area, which had been completely excised 3 years ago. In reviewing the...

The treatment of symptomatic calcifying tendinitis of the rotator cuff is usally medical. Whereas, chronic and painfull features can beneficiate of a surgical treatment. With shoulder arthroscopy it's possible to remove the type A and B calcifications and to perform a bursectomy and acromioplasty in type C uncollected. The clinical and radiological results with one year of follow-up upgrate 90%...

An investigation of the different steps in the method of Weil-Malherbe & Bone (1949), as modified by Taylor (1953), has led to an altered procedure for citric acid determination, with increased sensitivity and accuracy. The main modifications involved are the use of (i) a higher concentration of sulphuric acid during the formation of pentabromoacetone, and (ii) a thiourea-borax-sodium sulphide ...

Calcifying epithelial odontogenic tumor is a rare lesion. We report the imaging features of a calcifying epithelial odontogenic tumor. The imaging including conventional radiograph, CT and MR imaging revealed a well-defined lesion in the alveolar bone of the left maxilla, which contained an impacted tooth and some small radiopacities. CT and MR imaging demonstrated a contrast enhancement mainly...
