There is no doubt that the conditioned food saiivary reflexes are influenced by the intensity of hunger. However, there is no agreement as to whether this influence is direct or mediated by motor behavior. The data are also conflicting concerning the effect of hunger or satiation upon the unconditioned salivary response. Thus, Finch (1938) found that hunger affects the conditioned and unconditi...

To develop potent and metabolically stable agonists for protease-activated receptor-2 (PAR-2), we prepared 2-furoylated (2f) derivatives of native PAR-2-activating peptides, 2f-LIGKV-OH, 2f-LIGRL-OH, 2f-LIGKV-NH(2), and 2f-LIGRL-NH(2), and systematically evaluated their activity in PAR-2-responsive cell lines and tissues. In both HCT-15 cells and NCTC2544 cells overexpressing PAR-2, all furoyla...

There are some herbal plants in Iranian traditional system of medicine which are believed to be excellent remedies to alleviate the symptoms of xerostomia. The aim of the present study was to evaluate the effect of systemic administration of seven different herbal extracts on the rate of salivation in rats. The extracts of 7 herbs; Zingiber officinale Roscoe (Zingiberaceae), Citrus sinensis (L....

Plant viruses are primarily transmitted by insect vectors and virus infection may influence on the vectors' feeding behaviors. Using an electrical penetration graph, we detected that infection with the Southern rice black-streaked dwarf virus (SRBSDV) in the white-backed planthopper (WBPH) and in rice plants both altered the vector's feeding behavior. When viruliferous WBPH (carrying SRBSDV) we...

Stomatopyrosis of 'burning mouth' syndrome, in a narrower sense of definition, is a condition characterized by sensation of burning and heating in mouth, despite its normal mucosa. This research has been directed towards treatment of stomatopyrosis, putting emphasis on the implementation of psychopharmacotherapy and psychotherapy. The research was conducted on altogether 120 respondents sufferi...

Rats secrete saliva in response to heat. In the present study, details of thermal salivation were investigated using the FOK rat in comparison with Sprague-Dawley (SD), Donryu, and ACI rats. The FOK rat is a strain inbred for genotypic heat adaptation and endures heat for long periods. Conscious rats of all four strains were exposed to 42.5 degrees C. The order of heat endurance times at this t...

background: the aim of the present study was to induce salivation in haemaphysalis longicornis to increase saliva production and to characterize the collection of proteins present in the collected saliva using on-chip-electrophoresis. methods: saliva of adult female engorged h. longicornis was collected by treatment with 0.2% dopamine hydrochlo­ride. all protein samples were characterized by sd...
