Granule enzymes

However, it is now recognised that neutrophils can contribute to host-tissue damage if they are activated to secrete reactive oxidants and granule enzymes, and if the local concentrations of anti-oxidants and protease inhibitors within the tissue are low or defective. Thus, inappropriate neutrophil activation leading to host-tissue damage has been implicated in reperfusion injury, Crohn s disease, adult respiratory distress syndrome (ARDS) and rheumatoid arthritis. In these conditions, it is envisaged that neutrophils accumulate in tissues and become inappropriately activated to secrete their cytotoxic products, which then initiate or contribute to host-tissue damage.

Enzymes should be added to the feed together with the pre-mix. Granulated enzyme products may readily be mixed with feed components, as they are based on normal feed components such as wheat or soy grits. A wide range of enzyme products are available. Enzyme products should contain specific enzyme activities necessary to degrade specific substances such as glucans, starch, protein, pectin-like polysaccharides, phytic acid, raffinose, stachyose, hemicellulose, and cellulose. 

AThe subunit has been confirmed for the insect (Merzendorfer et al, 1999) and chromaffin granule enzyme (Ludwig et al, 1998) and has recently been found in the yeast enzyme (Sambade and Kane, 2004). The subunit compositions of the F-ATPase from the bacterium Escherichia coli, the vacuolar ATPase from yeast and bovine brain clathrin-coated vesicles, and the A-ATPase from the Archaeon Thermoplasma acidophilum are listed. Molecular masses are calculated from the amino acid sequence where available. 

Numerous and diverse biological functions are regulated by chemokines. In addition to the well characterized proinflammatory activities such as integrin activation, chemotaxis, lipid mediator biosynthesis, superoxide radical production, and granule enzyme release (reviewed in refs. 1-4), chemokines have been shown to suppress and stimulate angiogenesis (5-7), suppress hematopoiesis (8-10), suppress apoptosis (11), control viral infection (12,13), and effect leukocyte differentiation (14). Among the proinflammatory activities, chemotaxis in particular has received considerable attention as a target for novel antiinflammatory therapeutics (reviewed in ref. 15).

While there are still questions to be answered regarding the mechanisms of CTL-mediated cytotoxicity at mucosal surfeces, the current consensus is that multiple mechanisms, including perforin secretion, granule enzyme secretion and initiation of apoptosis, may account for CTL-mediated cytotoxicity (Smyth et al., 1992).

In terms of enzyme product formulations, Hquid and granulated enzymes are used. Cellulase is combined with surfactants to give a cleaner finish. 

Secondly, in neutrophils and monocytes the oxidizing potential of H2O2 is greatly enhanced by the primary granule enzyme myeloperoxidase (MPO), which utilizes H2O2 to oxidize chloride ions to hypochlorous acid (HOCl). 

Biological activities of LTB4 are measured by che-motactic assay, granule enzyme release assay, superoxide generation, hamster cheek pouch vascular permeability assay, rat mesenteric venule leukocyte adherence and emigration assay, lymphocytes proliferation assay, and leukocyte adhesion assay.
