We previously demonstrated the critical role of noradrenergic transmission within the ventral part of the bed nucleus of the stria terminalis (vBNST) in pain-induced aversion. We showed that activation of β-adrenoceptors in this brain region by intra-vBNST injection of isoproterenol, a β-adrenoceptor agonist, produced aversive responses. In the present(More)
Quantitative histochemical analysis of the secretory cells producing the different types of glycoproteins were examined in the chicken nasal cavity with and without moderate levels of SO2 exposure for 14 days. On the nasal maxillary concha of chickens, the number of acinar gland cells containing glycoproteins was significantly reduced on the 1st, 7th and(More)

It has been known that linoleic acid is converted to arachidonic acid in the body, and its process has gradually become clear. However, it is still unknown to what compound arachidonic acid is changed. According to the report of Davis et all) arachidonic acid labeled with C14 is incorporated into docosapentaenoic acid (22:5•¢)4.7.10.13.16 in the body of(More)
Chickens were exposed to SO2 in relatively low concentrations (3.4 to 18.5 parts per million (ppm)) for 1 to 14 days. A portion of their tracheas was embedded in water-soluble methacrylate, cut at 2 micrometer and stained with hematoxylin and eosin, Wright's stain, methyl green-pyronin, Alcian blue - periodic and Schiff, and for acid phosphatase.
