Decreased immunoreactivity has been reported for several neuropeptides in the aged suprachiasmatic nucleus (SCN). We compared somatostatin (SS) and substance P (SP) immunoreactivity (ir) in aged (20-26 months) and young (6 months) Wistar rats. The old rat SCN revealed a significant increase in SSir (2.6-fold) and SPir. The results show that not all SCN-neuropeptidergic systems decline with age,...
Background and Aim: The hormone receptor status in breast cancer has been pivotal in determining the likelihood of response to hormonal manipulation. Tumors which are both estrogen and progesterone receptor positive are much more likely to respond to anti-hormone therapy than negative tumors. There is well-established similarity between breast tissue and salivary glands. The aim of this study w...
Background: Aspergillus species has crucial role in respiratory allergy. This study was aimed to evaluate the pattern of IgE-mediated immune response to common aspergillus species including Aspergillus fumigatus, Aspergillus flavous, Aspergillus niger in type I aspergillus-hypersensitive patients’ sera. Methods: The prepared protein extract of Aspergillus species were dialyzed and the ...
The endocrine cells of Salmo trutta macrostigma stomach and pyloric caeca have been investigated using immunohistochemical techniques. 8 antisera were tested and 6 of them were detected in the endocrine cells serotonin, somatostatin, substance P, galanin, CCK and neuropeptide Y. These immunoreactive cells are described for the first time in the stomach and pyloric caeaca of Salmo trut...
