INDICATIONS:
IMPAIRED KIDNEY FUNCTION - Glomerulonephritis: In this disease there is a build up of protein in the basement membrane of the glomeruli of the kidneys. Fluids must pass through this basement membrane in the initial phase of the filtration of the blood by the kidneys. Recent research using an animal model of this disease "lends further support to the concept that enzymes capable of degrading immune complexes in situ can ameliorate glomerulonephritis".
HEAVY METAL TOXINS - Heavy metals such as lead (Pb) and mercury (Hg) exert their poisoning effect by binding to ionizable or sulfhydryl groups of proteins, including vital enzymes. Once these metals bind to an essential functional protein, such as an enzyme, they denature and/or inhibit it. This interaction of heavy metals to proteins can lead to degenerating diseases, nerve damage or even death. When taken on an empty stomach, it should be noted that protease is readily taken up into the mucosa cells of the intestine and passed into blood circulation. Clinical observations have noted that upon high intake of TPPTM Protease, heavy metal concentrations have been significantly decreased in the blood.
MODULATION OF THE IMMUNE SYSTEM - As a result of their coupling to a2M, Tzyme\Z proteolytic enzymes exhibit an increased binding of several very important cytokines (hormones-like molecules which have a powerful influence on immune cells) such as Transforming growth factor-beta (TGF-b), and Tumor Necrosis Factor-alpha (TNF-a). Studies have indicated that oral hydrolytic enzymes affect cytokine synthesis and modulatory effects. For instance, TNF-a synthesis, which is a necessary step in host defense against tumor cells, is impaired when experimentally inactivated oral proteolytic enzymes were used. Thus, active, GI stable and functional oral enzymes that are absorbed in the blood stream can provide therapeutic applications. In addition, studies have shown that oral proteolytic enzymes increased the tumoricidal and cytotoxic activities of polymorphonuclear neutrophils. COMPONENT BENEFITS:
TzymeTM Protease Blend in TPPTM Protease provides vital systemic benefits that include support of adequate blood rheology for optimum flow of immune cells, their meditating molecules, hormones, blood cells and other vital molecules and cells. The superb absorption abilities and high functionality of this product are certain to enhance and optimize overall protein hydrolysis. These benefits, in turn, facilitate and support a wide array of metabolic processes.

Bromelain, an important addition to the TzymeTM Protease Blend, is a protease derived from the pineapple plant. It has been used for many years as a digestive aid, anti-inflammatory and burn debridement agent. Its actions help to prevent swelling/edema, promote smooth muscle relaxation, inhibit platelet aggregation, and enhance antibiotic absorption. Bromelain is also used in cancer treatment, ulcer prevention, sinusitis relief, appetite inhibition and shortening of labor. Proteolytic enzymes administered orally improved the survival time, the hematological parameters of spontaneous lymphoblastic leukemia in rats, and the metastasis and survival time of mice with Lewis lung carcinoma.

Several hypotheses have been put forth as to the mechanisms by which proteolytic enzymes modulate the immune system to control and eliminate tumors. Some studies indicated that proteolytic enzymes selectively remove some adhesion molecules such as CD4, CD44, B7-1, ICAM-1, B7-2, CD45RA, CD6, CD7, E2/MIC2, and Leu81/LAM 1 from cell surfaces According to Hale et al. the removal of these surface molecules has markedly enhanced CD2 mediated T-cell activity.

Some studies have implied that by removing the glycoprotein CD44, some proteases help control the tumor growth of certain types of cells. This selective removal of some mediator proteins, and the regulation of cytokines constitute some factors by which proteolytic enzymes are thought to modulate the immune system and act as biological response modifiers."
