. The role of prostaglandin synthesis inhibition is discussed. Keywords : Skin; nerve endings; hydrogen ions; protons; sensory; aspirin; salicylic acid. 1. INTRODUCTION Local tissue acidosis is to be encountered in several painful conditions such as in car- diac ischemia, in fracture-related hematomas

In: Primary Sensory Neuron

epi- dermal sensory perception takes place by means of primary receptor cells. The cell bodies of these receptor cells are located below the epi- dermis, and free nerve endings extend from them to the epidermal sur- face. By means of light microscopy, the rich sensory regions of the epi- dermis, as

guards hairs and most of the vellus hairs are touch organs. The sinus and guard hairs are equiped with Merkel endings, free nerve endings, palisades of lanceolate nerve endings and pilo-Ruffini complexes. The total number of nerve endings varies in guard hairs between 50-200 and between 500-2000 in sinus

. In this proccdure, the tips of upper and lower beak are removed in the young animal. The beak-tips of a chicken contain considerable concentrations of mechanoreceptors and free nerve endings (DESSERICH et al., 1983; GENTLE & BREWARD, 1986; GENTLE, 1989). Debeaking means removal of these sense organs

Also a modified Allochrome staining procedure on tissue samples was performed to detect glycogen, which is known to occur in discoidal nerve endings of tactile sense organs of reptiles. Light microscopic slides revealed glycogen

nerve endings or sensillae. It is possible that esterases, which were clearly demonstrated in these organs at all stages of the life cycle of Meloidogyne, may have an active role in the nematodes' sensory system in the same way that acetylcholinesterase is associated with activity of the nervous system
