Studies on the Mechanism of the Plasma 17-hydroxy- Corticosteroid Elevation Induced in Man

The administration of estrogens to man produces sustained elevation above normal levels of plasma 17-hydroxycorticosteroids (17-OHCS) (1, 2). The elevated levels of plasma 17-OHCS are associated with an augmented response of plasma levels of these steroids to exogenous adrenocorticotropic hormone (ACTH) and with a marked delay in the rate of clearance of exogenous cortisol from plasma (2). The ...

Serum Iron Concentration in Children with Giardiasis

SUMMARY Giardia is a protozoan parasite which exists in the small intestine in man. This parasite could act as a barrier against fat absorption. It also results in anemia as a result of interference with folic acid vitamin B6 and probably iron absorption. In this study a total of 198 infested and 35 non­infested school children were studied for serum Iron and TIBC. The results showed the Iron...

Comparative Analysis of CD4+ and CD8+ T Cells in Tumor Tissues, Lymph Nodes and the Peripheral Blood from Patients with Breast Cancer

Background: CD4+ and CD8+ T cells are the main types of lymphocytes in cell-mediated immunity and play a central role in the induction of efficient immune responses against tumors. The frequencies of T cell subtypes in the peripheral blood and tumor tissues, and draining lymph nodes (dLN) can be considered as useful markers for evaluation of the immune system in cancers. Methods: In this study,...

Expression analysis of beta-secretase 1 (BACE1) enzyme in peripheral blood of patients with Alzheimer\'s disease

Background: Recent evidence has indicated that beta-secretase 1 (BACE1) is involved in the production of amyloid beta (Aβ) in patients affected with Alzheimer’s disease (AD). Therefore; the purpose of this study was to measure mRNA and plasma levels of BACE1 in AD patients, as an early diagnosis biomarker for such individuals. Methods: A total number of thirty AD patients and thirty normal sub...
