Candyce symptoms and conditions

Singulair does interact with the astrocyte in the brain.

The role of the cysLT1 receptor (Singulair blocks this receptor) and the astrocyte in the brain has been studied. For anyone from Merck to say that there are no mechanisms by which Singulair can affect the
brain is ludicrous. If the Chinese researchers are correct, then Singulair very clearly affects the brain. Certainly, we don't know exactly how or when the effect would be good or bad. Under what circumstances would it be beneficial and under what circumstances would it be harmful.

For quite a while, researchers have been hypothesizing about the role of the astrocyte in brain function. If we go to look for theories, we will find them. Here is the theory of Dr. Dale Antanitus. I am no here to promote anyone's theory in particular but just to point out that they exist.

We can see that the Chinese researchers have gone forward to look at potential links between the cysLT1 receptor (Singulair receptor) and inflammatory response in the brain. The 2008 study showed a link between the astrocyte and the cysLT1 receptor (Singulair receptor)

We recently found that 5-lipoxygenase (5-LOX) is activated to produce cysteinyl leukotrienes (CysLTs), and CysLTs may cause neuronal injury and astrocytosis through activation of CysLT(1) and CysLT(2) receptors in the brain after focal cerebral ischemia. However, the property of astrocyte responses to in vitro ischemic injury is not clear; whether 5-LOX, CysLTs, and their receptors are also involved in the responses of ischemic astrocytes remains unknown. In the present study, we performed oxygen-glucose deprivation (OGD) followed by recovery to induce ischemic-like injury in the cultured rat astrocytes. We found that 1-h OGD did not injure astrocytes (sub-lethal OGD) but induced astrocyte proliferation 48 and 72 h after recovery; whereas 4-h OGD moderately injured the cells (moderate OGD) and led to death 24-72 h after recovery. Inhibition of phospholipase A(2) and 5-LOX attenuated both the proliferation and death. Sub-lethal and moderate OGD enhanced the production of CysLTs that was inhibited by 5-LOX inhibitors. Sub-lethal OGD increased the expressions of CysLT(1) receptor mRNA and protein, while moderate OGD induced the expression of CysLT(2) receptor mRNA. Exogenously applied leukotriene D(4) (LTD(4)) induced astrocyte proliferation at 1-10 nM and astrocyte death at 100-1,000 nM. The CysLT(1) receptor antagonist montelukast attenuated astrocyte proliferation, the CysLT(2) receptor antagonist BAY cysLT2 reversed astrocyte death, and the dual CysLT receptor antagonist BAY u9773 exhibited both effects. In addition, LTD(4) (100 nM) increased the expression of CysLT(2) receptor mRNA. Thus, in vitro ischemia activates astrocyte 5-LOX to produce CysLTs, and CysLTs result in CysLT(1) receptor-mediated proliferation and CysLT(2) receptor-mediated death. (c) 2007 Wiley-Liss, Inc.

The astrocyte has been studied to see how it functions in the brain. The astrocyte:

1. may perform a role in the physical structuring of the brain
2. may perform a role in providing neurons with nutrients
3. may perform a minor role in the maintenance of the blood brain barrier
4. may perform a role in neurotransmitters
5. may perform a role in the regulation of ion concentration in the extracellular spaces
6. may perform a role in neuronal regulation of blood flood
7. may perform a role in the protection and repair of neurons

TO LIE TO PEOPLE REGARDING THEIR HEALTH IS CRIMINAL AND SHOULD BE PROSECUTED. PEOPLE OUT THERE ARE GETTING SICKER IF THEY ARE EXPERIENCING SIDE EFFECTS BECAUSE MERCK IS LYING. SOME PEOPLE MAY NOT EXPERIENCE SIDE EFFECTS BUT WHY NOT TELL THE TRUTH AND SAY THAT THERE COULD BE SOME PEOPLE WHO HAVE PSYCHIATRIC SIDE EFFECTS BECAUSE THERE IS A PATHWAY FOR THAT TO HAPPEN.

My name is Candyce Donovan and I am a healthy 38 year old ---healthy except for an occasional cold or sinus infection. A few years ago I was put on the drug Singulair to help cure an allergy type infection. I was only on it for a few weeks and discontinued it myself because it was making me worse. Earlier last year, I went to a different doctor for the same type of thing and was put on the drug again. At time while on the drug I had a few "episodes" where my body was shaking while I was sleeping and I thought I was just having a bad dream. Then in August of 2007, I experienced 2 grand mal seizures while sleeping each one lasting about an hour from the time I had the seizure til the time I came out of it... and was in the hopsital for 2 days. I had numerous tests done and things like a brain tumor etc were ruled out, and it was the conclusion of the ER doctors that my seizures were brought on by a very bad case of sinusitis as that was the only thing that showed up on my tests. At that time my sister brought in the medication that I was on at the time...the Singulair...and the doctors said that that would not cause seizures. The Neurologist that I went to disagreed with them and said that we would never find a cause. I continued on the drug until early December , having another seizure in November. I have now since November, moved in with my sister for the 6 months or more that I have been with out my license as in NY state one cannot drive for 6 months after having a seizure....you have to be totally seizure free for those 6 months, and it was the advice of the doctors to not stay alone. I went to see another Neurologist who again said that there would never be a known cause for the seizures, and in fact he diagnosed me with having epilespy/seizrue disorder....up until August I had never had a seizure. An uncle of mine had seizures when he was a baby that lasted until his teens but the Neurologist stated that he didnt think that was passed on to me. With the recent findings with the Singulair drug that are on the website now...I am finding that I have had many of the side effects and I believe this was the cause of my seizures as my seizures co-incided with the frame time I was on the drug.
