The distribution and density of innervation by saphenous nerve C-fibres has been demonstrated, in the intact rat and following nerve injury, using a dye-labelled plasma extravasation technique. In the intact rat the area demarcated by the dye corresponded to the area supplied by the whole nerve as determined by dissection and electrophysiologically. This(More)
PURPOSE Although all contact lenses (CLs) are applied initially to the eye directly from a packaging solution, little is known about the effects of these solutions on human corneal epithelial cells (HCECs). Due to the porous nature of CL materials, they have the potential to sorb components of the packaging solution during storage, which could then be(More)
PURPOSE Multipurpose solutions (MPS) are used daily to clean and disinfect silicone hydrogel (SiHy) contact lenses. This in vitro study was undertaken to identify the potential for interaction between MPS, SiHy surface treatments, and lens materials, which may lead to changes in the response of human corneal epithelial cells (HCEC) to MPS-soaked lenses.

Corticotropin-releasing factor (CRF) administered intracerebroventricularly produced both a rapid, greater than 50% reduction in splenic natural killer (NK) cytotoxicity and a prolonged elevation in plasma corticosterone levels. In the first 60 minutes following CRF, fivefold increases in corticosterone levels were associated with the suppression of NK(More)
Neuroactive peptides, including the enkephalins (Met- and Leu-enkephalin; ME, LE) and substance P (SP) are known to be present in the mammalian carotid body, an arterial chemoreceptor organ sensitive to the O2, CO2 and pH levels in blood. The principal parenchymal (type I) cells of the organ, which receive sensory innervation from the carotid sinus nerve(More)
We have previously reported that the bile acids chenodeoxycholate (CDCA) and ursodeoxycholate (UDCA) decreased PGE1-induced cAMP production in a time- and dose-dependent manner not only in hepatocytes but also in nonhepatic cells, including dermal fibroblasts. In the present study, we investigated the physiological relevance of this cAMP modulatory action(More)
Genetic variations of far-reaching consequences have been established between spontaneously hypertensive rats (SHR) and their controls, Wistar Kyoto rats (WKY). The SHR strain is the most widely used model for the study of genetic hypertension. Calcium homeostasis in the vascular smooth muscle (VSM) is controlled by calcium channels and calcium pumps(More)
