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.
This paper demonstrates that a group of proteins, representing a major secretory component of cattle conceptuses, is immunologically related to ovine trophoblast protein-1 (oTP-1), a principal product of culture Day 13 to 21 sheep conceptuses. Conceptuses from cows (Day 17-18) and ewes (Day 16-17) were cultured for 24 h in the presence of L-[3H]leucine. By using a rabbit antiserum to oTP-1 and ...
Since gastrin and its related peptides are secreted by a minority population of widely dispersed cells in mamamalian tissues it has, in the past, been difficult to study the subcellular aspects of their secretion. From published reports (1, 2) it seemed possible that a satisfactory system for such studies might be provided by the skin of certain amphibians such as Xenopus laevis since in these ...
background : ascaridia galli , the largest nematode of small intestine of birds, especially the native poultry, may give rise to serious illness, pathological defects and economical losses even in modern poultry production systems. although various measures have been undertaken to vaccinate poultry against a.galli , no satisfactory results were obtained so far. however, there is no report on th...
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...
in the present study, pancreas glands in mehraban breed of female sheep were histomorphometricallystudied in four different age groups included: fetus, newborn, sexually mature and old ages. the results ofhistomorphometrical analysis with regard to frequency and percentage of parenchymal and stromal structures such as, exocrine secretory units, secretory ducts, blood vessels, islets of langerha...
The exocrine protein rat anionic trypsinogen has been expressed and is secreted from the murine anterior pituitary tumor cell line AtT-20. We examined which secretory pathway trypsinogen takes to the surface of this endocrine-derived cell line. The "constitutive" pathway externalizes proteins rapidly and in the absence of an external stimulus. In the alternate, "regulated" pathway, proteins are...
