The Mystery of Acupuncture Partly Explained In Rat Study 159

hackingbear writes: A biological mechanism explaining part of the mystery of acupuncture has been pinpointed by scientists studying rats. The research showed that applying electroacupuncture to an especially powerful acupuncture point known as stomach meridian point 36 (St36) affected a complex interaction between hormones known as the hypothalamus pituitary adrenal (HPA) axis. In stressed rats exposed to unpleasant cold stimulation, HPA activity was reduced (abstract). The findings provide the strongest evidence yet that the ancient Chinese therapy has more than a placebo effect when used to treat chronic stress, it is claimed. "Some antidepressants and anti-anxiety drugs exert their therapeutic effects on these same mechanisms," said lead investigator Dr Ladan Eshkevari, from Georgetown University medical center in Washington DC.

                Real therapies that use electricity are Electroconvulsive Therapy and Electric Muscle Stimulation. There's no need to puncture the skin. These quacks are just adding some risk of infection to what would otherwise be an almost perfectly safe therapy.

            The Chinese concept of chi doesn't really match mitochondria very well. Except in very specific cases, mitochondria don't flow anywhere, and they aren't energy. The energy that does flow is in the form of glucose in the blood, and you can't change it much, nor the functioning of the mitochondria, by traditional methods of affecting chi.

        The study needs to be expanded upon, but it showed an effect. It was an effect that current models of physiology would call extremely unlikely (stimulate the shin, block stress hormones) but is predicted in the study of acupuncture.

        It doesn't go far enough, but it does provide evidence. The people I was talking about here can plug their ears and dribble about how this or that are not perfect, but nevertheless, it does provide evidence. That is, it contributes to proof.

        This is not skepticism. Skeptics accept

        • Honestly this is a case where I've learned to reason heuristically. I've seen many studies of this nature, I don't know what the specific flaws in the study might be (though I can think of many potential ones) and I would be very shocked if in a few years this led to a clinically validated form of something that's recognizable as acupuncture.

          Skepticism involves being skeptical about your own deductive abilities, this study shifts my beliefs slightly, but overall I realize I'm not qualified to accept this st

            The people I was more or less chastising are the ones who were dismissing the study out of hand and steadfastly denying that there is any evidence at all for acupuncture.

  • Yeah 1 point seem to have an effect. But is it 1) the effect predicted by chinese acupuncture and 2) all other point do pretty much nothing from previous study and deliver effect with shame acupuncture (giving the impression of needle going in but not penetrating). Basically broken clock.
