Dear Tanya
Thank you very much for both information.
They are really very interesting.

Effect of hemorrhage, reinjection of blood and dextran on the reactivity of the sympathetic and parasympathetic systems
Hello, All --- I found this interesting ......... The title is a bit deceptive as it appears that they did reinject blood without the dextran.

Effect of hemorrhage, reinjection of blood and dextran on the reactivity of the sympathetic and parasympathetic systems

Summary The posterior hypothalamus and the central end of the sciatic nerve have been stimulated in anesthetized cats before and after bleeding and also after reinjection of blood or Dextran. The sympathetic responses indicated by the contraction of the nictitating membrane (n. m.), the rise in blood pressure and the acceleration of the heart rate are increased after bleeding but diminished after reinjection of blood or Dextran. The parasympathetic reactions resulting in a decrease in heart rate and fall in blood pressure are increased after reinjection and Dextran. These changes are abolished by sino-aortic denervation. The contraction of the denervated n. m. in response to a standard stimulus is increased after bleeding and reduced after injection of Dextran. A pressor response to a hypothalamic stimulus may be converted into a depressor response through injection of blood or Dextran. The experiments illustrate the principle that the autonomic nervous system may be ldquotunedrdquo via the baroreceptors.

Auto-hemic therapy: treating your blood with your own blood
Hello, again - This old book is of interest to me (you may already know about it, but if not, I think it is worth sharing) . This is what really has me particularly interested - (and I would appreciate anyone's comments on this) : In cases where there is an absence of usable veins - just a couple of very small veins, attempting to do the auto-hemotherapy every 7 days with 5 ml of blood (or even less), would be difficult or impossible because small veins require a much longer time to get the blood from. In the case of using a thin needle for a small vein, how long do you have to finish collecting the blood before you must reinject it? In this book, starting on page 17, there is the section entitled, "Explanation of Method" - they discuss the possiblilty of using blood collected from a finger prick --- this would avoid the problem of damaging the small, few veins that may be available. This, of course, is a very different method than used by Dr. Moura. It involves sterile collection of blood which is then added to a sterile solution and then small amounts reinjected (not necessarily into veins - again, saving poor veins from damage that may subsequently become unsuable). He even mentions that the blood solution may be taken by mouth - but he gives no details on how much and how often. Does anyone here know anything about this method?
Does anyone have any experience or knowledge on the problem of not being able to get blood from very small veins quickly enough to reinject before it clots/coagulates? How long can you wait before you reinject the blood? The first blood taken out into the syringe will start clotting perhaps before all of the blood has been withdrawn. Any comments would be appreciated.
Thank you,
Tanya
