Deans' stroke musings: Cerebrovascular protection by various nitric oxide donors in rats after experimental stroke.

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Cerebrovascular protection by various nitric oxide donors in rats after experimental stroke.

So does this mean we should get NO right after the stroke? Who's going to answer that question?
From 2006, so once again it just shows how badly information about stroke is not followed up.

Abstract

The efficacy of nitric oxide (NO) treatment in ischemic stroke, though well recognized, is yet to be tested in clinic. NO donors used to treat ischemic injury are structurally diverse compounds. We have shown that treatment of S-nitrosoglutathione (GSNO) protects the brain against injury and inflammation in rats after experimental stroke [M. Khan, B. Sekhon, S. Giri, M. Jatana, A. G. Gilg, K. Ayasolla, C. Elango, A. K. Singh, I. Singh, S-Nitrosoglutathione reduces inflammation and protects brain against focal cerebral ischemia in a rat model of experimental stroke, J. Cereb. Blood Flow Metab. 25 (2005) 177-192.]. In this study, we tested structurally different NO donors including GSNO, S-nitroso-N-acetyl-penicillamine (SNAP), sodium nitroprusside (SNP), methylamine hexamethylene methylamine NONOate (MAHMA), propylamine propylamine NONOate (PAPA), 3-morpholinosydnonimine (SIN-1) and compared their neuroprotective efficacy and antioxidant property in rats after ischemia/reperfusion (I/R). GSNO, in addition to neuroprotection, decreased nitrotyrosine formation and lipid peroxidation in blood and increased the ratio of reduced versus oxidized glutathione (GSH/GSSG) in brain as compared to untreated animals. GSNO also prevented the I/R-induced increase in mRNA expression of ICAM-1 and E-Selectin. SNAP and SNP extended limited neuroprotection, reduced nitrotyrosine formation in blood and blocked increase in mRNA expression of ICAM-1 and E-Selectin in brain tissue. PAPA, MAHMA, and SIN-1 neither protected the brain nor reduced oxidative stress. We conclude that neuroprotective action of NO donors in experimental stroke depends on their ability to reduce oxidative stress both in brain and blood.
