In this study, we investigated the underlying cytoprotective mechanism of ?1-adrenoceptor activation in rat submandibular glands after irradiation.Study design: Rats were locally irradiated using a linear accelerator in the head and neck region with a dose of 20Gy. After irradiation, phenylephrine (5mg/kg) was injected intraperitoneally for 7 successive days and the submandibular glands were then collected. The antiapoptotic effect of phenylephrine on the gland was examined by TUNEL, the proliferative cellular nuclei antigen (PCNA) was determined by immunohistochemistry, and the activation of c-Jun N-terminal kinase (JNK) was detected by Western blot.Results: The irradiation only group showed severe atrophy, increased apoptosis, enhanced cell proliferation, and the phosphorylation of JNK …

The purpose of the study was to evaluate the combined use of two rapid, semiquantitative detection kits (Saliva?Check Mutans and Saliva?Check IgA Mutans) to assess caries risk using the Cariogram computer?based program as a reference method. Stimulated saliva samples were collected from 71 subjects, 20–73 yr of age, and the number of Streptococcus mutans per ml of saliva was measured using Saliva?Check Mutans. After 15 min, a red line in the test detection window indicated >5 × 105 colony?forming units (CFU) of S. mutans per ml of saliva. The concentration of salivary IgA in relation to the number of mutans streptococci was examined using the Saliva?Check IgA Mutans test kit. The presence or absence of a red line after 15 min indicated a high or a low concentration …
