Using the "Bi-Digital O-Ring Test Imaging Technique", the author has been able to accurately localize meridians and acupuncture points that correspond to specific internal organs and has found that most general patterns of meridians and the number of acupuncture points on each of the meridians of specific internal organs of the 12 main internal organs described in the literature of ancient Chinese medicine, are more or less correct, with the exception of some variations and inaccuracies. Each meridian of specific internal organs was found to be connected to the organ representation area in the cerebral cortex of specific internal organs. The acupuncture point has an area and occupies 3-dimensional space. It has a circular or slightly oval boundary with diameter in the range of 3 mm to 2.7 cm, although 6-12 mm are the most common diameters in human adults, with the exception of the area outside the corners of the nailbeds of the fingers and toes. Using the "Bi-Digital O-Ring Test Molecular Identification Method", the author also found that within the boundary of most acupuncture points and meridian lines (including Heart, Stomach, and Triple Burner) were high concentrations of neurotransmitters and hormones, including Acetylcholine, Methionine-Enkephalin, Beta-Endorphin, ACTH, Secretin, Cholecystokinin, Norepinephrine, Serotonin, and GABA. On all these meridian lines, in addition to the above neurotransmitters and hormones, Dopamine, Dynorphin 1-13, Prostaglandin E1 (PGE1) and VIP were found, but the latter do not usually exist within the boundary of the acupuncture point with the exception of the center midline of the acupuncture point where the meridian line is situated. Serotonin, Norepinephrine, and Cholecystokinin appeared in either one of the above 2 patterns, depending on the individual. Usually, no significant amounts of these neurotransmitters and hormones were found at the surrounding area outside of meridian and acupuncture points. However, the essential amino acid L-Tryptophan (which is a precursor of Serotonin), was usually found outside of the boundary of the acupuncture point and the meridian but not within the boundary of the acupuncture point and the meridian. Wherever Serotonin appeared, L-Tryptophan disappeared significantly and when the Serotonin disappeared, L-Tryptophan reappeared. In addition to the above common neurotransmitters and hormones, the Heart meridian had additional Atrial Natriuretic Peptide in both the meridian and its acupuncture points. Similarly, the Stomach meridian had additional Gastrin in both the meridian and its acupuncture points. Likewise,the Triple Burner meridian had additional Testosterone (in the male) and Estrogen (especially Estriol and Estradiol in the female.

In sheep as in other species, intracerebroventricular (ICV) administration of picomolar doses of several peptide hormones affects food intake and rumination, suggesting that these hormones play a role in the physiological control of feeding behavior. Their effects depend on their duration (short vs long-term) and/or their nature (orexigenic vs anorexigenic). Among the short-term satiety factors, CCK8, CRF and calcitonin, administered ICV, decrease food intake by reducing the rate (CCK8) or the duration (CRF, calcitonin) of ingestion; in contrast, the gastrin group of peptides (gastrin 17, penta or tetragastrin) reduces food intake by promoting an early period of rumination. Opioid peptides such as Met-enkephalin and Dynorphin initiate food intake in satiated sheep and are supposed to be active in the short-term regulation of food intake in these ruminants. In contrast both calcitonin gene-related peptide (CGRP) and growth hormone-releasing factor (GRF) increase the daily food intake, when ICV injected, but their centrally mediated orexigenic effects depend on the regimen and the digestive status. These results confirm the species differences observed in food intake regulation and the major role of the C.N.S. in controlling feeding behavior and energy balance in ruminants.

Nanomolar concentrations of neurotensin caused a dose-dependent contraction of the longitudinal muscle layer of the guinea-pig ileum. The contractile activity of neurotensin was partially blocked by tetrodotoxin or atropine, indicating that a component of the neurotensin-mediated contraction is indirect in nature and likely involves the release of endogenous acetylcholine from nervous terminals in the myenteric plexus. Dynorphin and related peptide fragments also blocked in part the neurotensin contraction; the potency of this opioid peptide was about the same as that of atropine. Other peptides and alkaloids tested for ability to block the neurotensin contractures included the enkephalins, beta-endorphin, normorphine and the ketocyclazocines; all these opioids inhibited in a dose-dependent fashion the neuronal component of the excitatory effect of neurotensin. The potency of these compounds to reduce the contractions of neurotensin showed good correlation with the potency of these agents to depress by 50% the electrically evoked neuromuscular twitches in the same tissue (r = 0.99); in these tests dynorphin was found to be the most potent of the endogenous opioid-like peptides. The dynorphin blockade was selective to the excitatory effect of neurotensin because the opioid peptide did not antagonize the contractile action of acetylcholine, histamine, substance P, angiotensin II, bradykinin, Ba++ or K+ ions. In addition, somatostatin, vasointestinal peptide, gastrin or adenosine did not modify the potency of neurotensin whereas thyrotropin releasing hormone and epinephrine caused a modest doubling of the neurotensin EC50. The inhibitory action of dynorphin was reduced in the presence of naloxone, suggesting that the interaction involved opiate receptors. Morphine tolerance was not extended to the inhibitory action of dynorphin as evidenced by the finding that the potency of dynorphin-(1-13) to block the neurotensin responses was increased after chronic morphine exposure. In contrast, the potency of dynorphin-(1-13) was significantly reduced in tissues rendered tolerant to the action of ketocyclazocine or ethylketocyclazocine, suggesting that the action of dynorphin could be partially mediated via occupation of K-opiate receptors. Thus, a cholinergic-neuronal component activated by neurotensin on the myenteric plexus appears to be under the inhibitory influence of opiate receptors, suggesting that dynorphin may play a role in the modulation of cholinergic synapses on the enteric nervous system.
