colloid carcinoma, also called mucinous carcinoma, is classified as a histologic variant of adenocarcinoma. because the colloid carcinoma of the biliary tree is exceedingly rare, the imaging characteristics and the clinical features of colloid carcinoma remain relatively unknown. we report a case of colloid carcinoma of the common bile duct and its accompanied metastatic lymphadenopathies with ...

Most pituitary tumors are benign conditions and rarely malignant. These divided into secretory non-secretory based on the tumor’s capability of secreting hormones. A study conducted in UK showed a prevalence 77.6 adenoma cases out 100000 people.

  SUMMARY Scolicidal agents are used by most surgeons during operations for hydatid cysts when these agents are injected into the cys t cavity, they can pass through the communicating passages between the cyst and bile ducts into the large intrahepatic and extrahepatic bile ducts and because of their caustic nature, they have the potential to damage the epithelium of ducts. This epithelial da...

background: to evaluate the immunological properties of leishmania major excreted- secreted (e-s) products on the progress of leishmaniasis in susceptible balb/c mice. methods: promastigotes of the leishmania major were cultured and e-s products were collected during the culture preiod. groups of balb/c mice (n= 12) were immunized with e-s products or whole antigen. animals were challenged with...

A fraction of secretion granules has been isolated from rabbit parotid by a procedure which was found to be especially effective in reducing contamination resulting from aggregation and/or cosedimentation of granules with other cell particulates. The fraction, representing 15 percent (on the average) of the total tissue amylase activity, was homogeneous as judged by electron microscopy and cont...

Ducts are widely used in an industry field. For example, air conditioning ducts, exhaust smoke elimination ducts and silencers have been various ducts. In general, the a flow vortices generated duct sometimes cause resonance phenomenon self-sustained tone. Once occurs, high level sound is suppression of this strongly quickly required. It necessary to know natural acoustic frequency for examinat...

Background The anatomy of the nipple has become clinically relevant. Diagnostic techniques access the breast through nipple ducts and surgeons offer nipplesparing mastectomy. There is variation in the number of ducts reported and little is known about the spatial location of ducts, their size, and their relationship to orifices on the surface. Methods Nipple specimens were taken from 129 consec...
