Abstract:
This study investigate the effects of four Chinese herbs for their potential therapeutic use as analgesics. It involved screening for inhibitors of enkephalin-hydrolysing enzymes, especially selective NEP inhibitors, mixed NEP/APN inhibitors and mixed NEP/ACE inhibitors. NEP was the key enzyme in the screening systems. Four Chinese herbs Yan (Corydalis yanhusuo T. Wang); Gou (Nauclea sinensis Oliv. ); Qiang (Notopterygium incisum Ting ex H.T. Chang); and Chuan (Ligusticum chuanxiong Hort.) were tested for their inhibitory effects on NEP activity measured in a rat kidney extract. Aqueous extrac

Abstract:
Injury causes increased pain sensation in humans and animals but the mechanisms underlying the emergence of persistent pathological pain states, which arise in the absence of on-going physical damage, are unclear. Therefore, elucidating the physiological regulation of such intractable pain is of exceptional biomedical importance. It is well known that endogenous activation of µ-opioid receptors (MORs) provides relief from acute pain but the consequences of prolonged endogenous opioidergic signaling have not been considered. Here we test the hypothesis that the intrinsic mechanisms of MOR signa

Neuronal nicotinic acetylcholine receptors (nAChRs) are ligand-gated cation channels that most notably influence dopamine (DA) release. In this thesis, I examine the role of nAChRs in mediating DA-related behaviors such as movement and drug dependence. To accomplish this, I utilized a “gain-offunction” knock-in mouse (the Leu9’Ala line) containing agonist-hypersensitive α4* nAChRs (* indicates other nAChR subunits in addition to α4 are within the receptor complex) that renders receptors 50-fold more sensitive to nicotine and acetylcholine than wild-type (WT) receptors.

So far the studies of tactile allodynia are focused on the functional alterations in the primary afferents and the spinal dorsal horn neurons, however, the role of brain in the tactile allodynia is still unclear.
