Acupuncture Effects

Some acupuncture effects are considered to be caused by interaction with nerve structures in and around the acupoints. The aim of the present study was to investigate the nerve structures that interact with the needle in acupuncture and to present their distribution in acupoint tissues. To do this, the microscopic anatomy and its alterations in the vicinity of the needle tract formed after experimental acupuncture in ST36 acupoint in rats were described by histological and immunohistochemical methods. Free nerve endings were seen in the epidermis, and surrounding hair follicles and sebaceous glands in the dermis. Muscle spindles and larger nerve fibres close to blood vessels were also observed deeper, in the muscular plane. Needling of the acupoint caused destruction and displacement of hair follicles together with their free nerve endings. Deeper, some muscle spindles and smaller nerves were displaced and disrupted. Larger nerves were not destroyed, but rather pushed aside by the needle. Furthermore, needle impact also caused degranulation of mast cells near the needle tract. The findings suggest multiple ways of interaction between acupuncture needle and the nerve structures of the acupoint. Acupuncture combines destruction, disruption and displacement of nerve structures, together with additional interaction with mast cells. Those mechanisms are involved in eliciting the needling sensation and are possibly associated with the systemic effect of acupuncture.

Cluster Headaches

It has been suggested that histamine plays an important role in the pathogenesis of cluster headache. In addition, both neurogenic and vascular components have been described during cluster headache attacks without an obvious anatomical link between them. Our ultrastructural observations of human temporal arteries from cluster headache patients and their comparison to those from a control group strongly suggest that mast cells may be this link. Mast cells in both groups show a very close apposition with nerve fibres, suggesting a functional interaction between them. Moreover, in the cluster headache group exclusively, adventitial mast cells show profound morphological modifications suggesting progressive degranulation. These data strongly suggest that mast cells could be directly or indirectly involved in the pathophysiology of cluster headaches.
