Reference ranges for urine tests are described below: Measurement Lower limit Upper limit Unit Urinary specific gravity: 1.003 [1] [2] 1.030 [1] [2] g/mL Urobilinogen:
Micrograph showing hemosiderin-laden alveolar macrophages, as seen in a pulmonary hemorrhage. H&E stain. An alveolar macrophage, pulmonary macrophage, (or dust cell) is a type of macrophage, a professional phagocyte, found in the airways and at the level of the alveoli in the lungs, but separated from their walls. [1]
[2] [9] Lipid-laden alveolar macrophages have been reported in cases of vaping-associated pulmonary injury. [10] [1] [11] The lipid-laden macrophage index (LLMI) can be calculated by counting 100 macrophages in a BAL specimen treated with a lipid stain and scoring each macrophage from 0 to 4 based on the amount of lipids present in the cell.
The activation of T H 1 and M1 macrophage is a positive feedback loop, with IFN-γ from T H 1 cells upregulating CD40 expression on macrophages; the interaction between CD40 on the macrophages and CD40L on T cells activate macrophages to secrete IL-12; and IL-12 promotes more IFN-γ secretion from T H 1 cells.
Urinalysis, a portmanteau of the words urine and analysis, [1] is a panel of medical tests that includes physical (macroscopic) examination of the urine, chemical evaluation using urine test strips, and microscopic examination.
Excessive systemic accumulations of hemosiderin may occur in macrophages in the liver, lungs, spleen, kidneys, lymph nodes, and bone marrow. These accumulations may be caused by excessive red blood cell destruction (haemolysis), excessive iron uptake/hyperferraemia, or decreased iron utilization (e.g., anaemia of copper toxicity) uptake ...
The level of hemosiderin-laden macrophage is also associated with pulmonary hemodynamics parameters which is used to evaluate pulmonary hypertension in the early stage of diseases. [ 16 ] Iron homeostasis has been associated with macrophage polarization and reprogramming despite unclear causality in cigarette iron. [ 13 ]
Idiopathic pulmonary hemosiderosis; Transfusional diabetes [2] [3] Organs affected: Hemosiderin deposition in the lungs is often seen after diffuse alveolar hemorrhage, which occurs in diseases such as Goodpasture's syndrome, granulomatosis with polyangiitis, and idiopathic pulmonary hemosiderosis. Mitral stenosis can also lead to pulmonary ...
