The human body consistently takes this tack when it senses an overload of a natural substance. For example, if you continually take large amounts of cortisone, a synthetic adrenal hormone, your own production of natural adrenalin will stop and your adrenals will gradually atrophy. Likewise taking thyroid will shut down your own natural thyroid production. Thus it stands to reason when you flood your brain with inordinate amounts of serotonin, the same sensing mechanism will begin to shut down some of your serotonin receptors (as happened in animal trials) in an attempt to control the overload. We don't know if they ever reactivate. We do know that organs like the thyroid and adrenals do not restore themselves.
CAMP factor is a diffusible, heat-stable protein produced by group B streptococci. This is a synergistic test between Staphylococcus aureus and Streptococcus agalactiae . S. agalactiae produces CAMP factor. S. aureus produces sphingomyelin C, which binds to red blood cell membranes. The two bacteria are streaked at 90 o angles of one another. They do NOT touch. The CAMP factor produced by S. agalactiae enhances the beta-hemolysis of S. aureus by binding to already damaged red blood cells. As a result, an arrow of beta-hemolysis is produced between the two streaks. The test is presumptive for S. agalactiae that produces CAMP factor.
The ONLY purpose of the parathyroid glands is to regulate the calcium level in our bodies within a very narrow range so that the nervous and muscular systems can function properly. This is all they do. They measure the amount of calcium in the blood every minute of every day... and if the calcium levels go down a little bit, the parathyroid glands recognize it and make parathyroid hormone (PTH) which goes to the bones and takes some calcium out (makes a withdrawal from the calcium vault) and puts it into the blood. When the calcium in the blood is high enough, then the parathyroids shut down and stop making PTH.
