We investigated the influence of vitamin E on mediator activity and release in a canine mastocytoma cell line (C2) as a model for canine atopic dermatitis. Cells were incubated without and with vitamin E (100 microm) for 24 h. The histamine and prostaglandin D2 (PGD2) release as well as the chymase and tryptase activity were measured. To stimulate the PGD2 and histamine release, cells were incubated with the wasp venom peptide mastoparan (50 microm) for 30 or 45 min. Nonstimulated as well as mastoparan-stimulated histamine and PGD2 release was reduced significantly in vitamin E-treated cells. The activity of chymase tended to decrease, but the tryptase activity of C2 cells was not influenced by vitamin E. These results indicate that vitamin E decreased the production and release of inflammatory mediators in C2 cells, suggesting that vitamin E might have a possible beneficial effect in inflammatory diseases.

SIDE EFFECTS:
It should be noted that in theory if one was to consistently suppress your natural estrogen levels for a long period of time, this would negatively impact your health, including your cholesterol. Due to the ability of Letrozole- to inhibit estrogen so much, this should definitely be a concern to most users. However the research that has focused on the relationship between use of letrozole and cholesterol levels is rather inconsistent in it's findings. Many studies have concluded that the compound is detrimental to both a user's HDL and LDL cholesterol levels, while other research has found no link. Obviously individuals are best served to monitor their cholesterol while using any compound via blood tests however barring that, letrozole should simply not be run for extended periods of time if at all possible. Doing so could cause serious medical complications.
Along with the issues related to blood lipids is the fact that many users complain that their libido is dramatically reduced when using the compound. This is related to the fact that estrogen is partly responsible for the regulation of an individual's sex drive. Since Letrozole- is so potent it can often drive estrogen levels too low and this inhibits a user's libido. To avoid this users can lower dosages, but some anecdotally report that even extremely low doses of the drug can cause problems. If this is the case a less potent compound such as exemestane or anastrozole may be a more appropriate option.

Calcium triggers the secretion of histamine from mast cells after previous exposure to sodium fluoride. The secretory process can be divided into a fluoride-activation step and a calcium-induced secretory step. It was observed that the fluoride-activation step is accompanied by an elevation of cyclic adenosine monophosphate (cAMP) levels within the cells. The attained high levels of cAMP persist during histamine release. It was further found that catecholamines do not markedly alter the fluoride-induced histamine release. It was also confirmed that the second, but not the first, step in sodium fluoride-induced histamine secretion is inhibited by theophylline. [23] Vasodilation and increased permeability of capillaries are a result of both H1 and H2 receptor types. [24]

If antihistamines and nasal sprays are not effective or not tolerated by the patient, other types of therapy are available. Allergy desensitization or immunotherapy may be needed. Allergy immunotherapy stimulates the immune system with gradually increasing doses of the substances to which a person is allergic. Because the patient is being exposed to the allergy-inducing substance, an allergic reaction can occur and this treatment should be supervised by a physician. Although the exact way allergy desensitization works is not completely known, allergy injections appear to modify or stop the allergic reaction by reducing the strength of the IgE and its effect on the mast cells. This form of treatment is very effective for allergies to pollen, mites, cats, and especially stinging insects (for example, bees). Allergy immunotherapy usually requires a series of injections ( allergy shots ) and takes three months to one year to become effective. The required length of treatment may vary, but three to five years is a typical course. Frequent office visits are necessary.

If one has Lyme – it is likely one has not been detoxing mercury well, and so starting at very low levels of zinc supplemetation is advised, like 15 to 30 mg only a few days a week to start, and building up. This is mostly to avoid detoxing mercury too fast. A binder needs to be used as well – like charcoal, clay, chlorella. blue green algae, etc. to avoid bouncing mercury through out the body. Some practitioners, such as Dr Klinghardt are saying with Lyme strive for zinc / copper balance and thus advise taking small amounts of copper with zinc to assist. However Dr Walsh seems to advise to supplement zinc well and high enough levels, especially where HPU (Pyrrole) is involved, which also is often the case with infection.
