Dietary fatty acids and the time elapsed from their intake are related to their composition in rat submandibular gland and salivary flow rates.

Objectives: The aim of this study was to analyze the influence of dietary fatty acids (FAs) and the time elapsed from their intake on FA tissue profile of rat submandibular gland (SG) and on its salivary flow rate (SFR). Do dietary FAs depending on the intake time modify their profile in SG and consequently the SFR?

Materials And Methods: Thirty-six adult male Wistar rats were fed on control diet (corn oil, CD, 18:2 n-6 FA) for 7 days and then divided into CD and two groups with replacement of corn oil by olive (OD, 18:1 n-9 FA) or chia (ChD, 18:3 n-3 FA) oils (1 and 30 day intake). Submandibular ducts were canalized to collect saliva for 20 min (μL/min).

Prostate-specific antigen: its relationship with alcohol intake and tobacco.

To determine the influence of alcohol and tobacco consumption on serum prostate-specific antigen (PSA) levels. 59 men participated in this study: 20 with prostate tumors (PT) and 39 without tumor diagnosis (prostate controls, PC) (mean 66 and 58 years, respectively). PSA was analyzed in serum samples and its values were compared through the Kruskal-Wallis nonparametric test.
