Subjects were determined to be in satisfactory zinc status via analysis of the zinc levels of their diet, hair, plasma, and saliva. During the low-zinc diet, concentrations of zinc in whole mixed saliva remained relatively stable f...

Several data strongly suggest a causative role of MMTV in humans, such as the presence of viral sequences in a hi...
Antimicrobial factors were analyzed in samples of whole saliva from 31 children, aged 0.8 to 3.8 years. When compared with the adult reference group, the children displayed similar levels of lysozyme, salivary peroxidase, and hypothiocyanite (OSCN-), whereas the amounts of immunoglobulins (isotypes A, G, and M), lactoferrin, myeloperoxidase, thiocyanate (SCN-), amylase, and protein were signifi...
BACKGROUND Exhaled breath condensate (EBC) is thought to contain substances of the lower airway epithelial lining fluid (ELF) aerosolized by turbulent flow. However, contamination by saliva may affect the EBC when collected orally. OBJECTIVE The purpose of this study was to compare the cytokine expression levels in EBC with those in saliva, and to clarify the influence of saliva on cytokine m...
