P-selectin and PSGL-1 are cell adhesion molecules, regulating the initial interactions between leukocytes and the blood vessel wall as well as between activated platelets and leukocytes. P-selectin is expressed on activated endothelial cells and platelets, while its major ligand PSGL-1 is expressed on leukocytes. Multiple studies have shown that these adhesion molecules are required for the nor...

To determine whether leukocytes express the angiotensinogen gene, we subjected circulating rat leukocytes and murine bone marrow cells to Northern blot analysis and hybridization with homologous angiotensinogen complementary DNA. Angiotensinogen messenger RNA sequences were detected in circulating adult rat leukocytes, in murine-irradiated and nonirradiated bone marrow stromal cells, and in an ...

The use of immunostimulants is an effort to increase the immune system in fish. Agar and alginate are phycocoloid derived from seaweed which function as immunostimulants. Research data collection was carried out for 60 days at Aquaculture Toxicology Environmental Installation, Cibalagung - Bogor. container used aquarium with a size × 40 50 cm, using aeration stocking density 15 fish / aquarium....

Background: As deficiency of innate immunity was found by us earlier in elderly (> 60) and also in leukemia patients, the innate immunity of blood leukocytes obtained from tumorous patients (carcinoma ovarii and adenocarcinoma endometrium), Alzheimer disease (AD) patients and control group in the same age was compared. Two of the mechanisms engaged in innate immunity were studied: — resistance ...

Leukocytes are classified as myelocytic or lymphocytic, and each class of leukocytes consists of several types of cells that have different phenotypes and different roles. To define the gene expression in these cells, we have performed serial analysis of gene expression (SAGE) using human leukocytes and have provided the gene database for these cells not only at the resting stage but also at th...

The metabolism of an essential amino acid, isoleucine, by human leukemic and gradient-separated normal human leukocytes of various types and maturity was studied. Blood leukocytes were isolated and incubated with (U-14C) isoleucine. Separation of metabolic intermediates was accomplished by sequential extraction. The rate of isoleucine incorporation into protein by immature cells from untreated ...

The aim of the scientific work is to study changes in hematological indicators chickens when they are kept at a high stocking density. In conditions current complex for formation eggs, 4 groups laying hens were formed. results showed that density 24.0 birds m-2 was accompanied by an increase their blood leukocytes 12.2%, heterophils – 1.8%, and decrease thrombocytes’ concentration 4.0%. Provide...

Background and Purpose Platelet aggregation plays an important role in the pathogenesis of thromboembolic cerebrovascular disease. Leukocytes can efficiently stimulate as well as inhibit platelet aggregability. We studied the influence of leukocytes on collagen-induced platelet aggregation in patients with acute ischemic stroke. Methods We investigated 23 patients within 2 days after stroke and...

Background & Objectives: Annually, many Muslims fast during the month of Ramadan worldwide. This practice has different favorable medical and physiological effects, such as improved serum lipid profile and blood glucose level due to changes in diet and sleep patterns. It has also been hypothesized that Ramadan fasting may affect the immune system. As reported, Ramadan fasting can influence the ...
