Methods: Female Wistar rats (n= 6 – 8/group) were fed low (LS- 0.15%) or normal (NS-1.3% NaCl) salt diet since the 1st day of gestation until delivery or LS during 1st (LS10) or 2 nd half of gestation (LS20). Body weight (BW), circulating glucose, insulin, leptin and C-peptide levels, glucose (GTT) and insulin tolerance test (ITT) and leptin receptor (LR) methylation were measured in male (M) and female (F) offspring at 12 weeks of age Results (mean±SEM, p< 0.05): BW, at birth (g, n=14 – 27/group) (M: NS = 6.5±0.1, LS = 5.5±0.1, LS10 = 6±0.1, LS20 = 4.8±0.1, F: NS = 6±0.2, LS = 5±0.1, LS10 = 6±0.1, LS20 = 4±0.1) was lower in LS, LS10 and LS20 than in NS, while at adulthood it was not different. Glucose was higher in LS (M=115±3; F=110±4) than in the other groups (M: NS=103±1; LS10=100±2; LS20=96±2; F:NS=101±2; LS10=100±2; 108±2). C-peptide was higher in LS (M=1117±152; F=509±27) than in NS (M=375±41; F=233±63) and lower in LS20 (M=97±15; F=76±9) compared to LS10 (M=528±112; F=378±45).Glucose was higher in LS M and F at 5 minutes of the GTT compared to NS offspring. Leptin, insulin, and ITT were not different. But LR methylation was increased in LS20. Conclusion: Sodium restriction during pregnancy leads to low birth weight and to modifications of glucose metabolism and LR methylation.conferenceObject Compound 21 Prevents Salt Induced Myocardial Hypertrophy(2016) DOPONA, Ellen Priscila Brito; FAVONI, Veronica; OLIVEIRA, Ivone Braga de; HEIMANN, Joel ClaudioconferenceObject Low sodium intake is associated with low birth weight and size only when given in the second half of gestation(2012) SIQUEIRA, Flavia Ramos de; SOUZA, Regiane Machado de; OLIVEIRA, Ivone Braga de; FURUKAWA, Luzia Naoko S.; HEIMANN, Joel ClaudioThis study examined the effects of maternal low sodium intake during different periods of pregnancy on dams and male (M) and female (F) offspring. Methods: Female Wistar rats (n= 6 - 8/group) were fed low (LS - 0.15%) or normal (NS - 1.3% NaCl) sodium diet since the 1st day of gestation until delivery or LS during the 1st (LS10) or 2nd half of gestation (LS20). Results: (mean±SEM, p< 0.05): Maternal body weight (g) was lower in LS and LS20 than in NS and LS10 at the 3rd week of gestation (LS = 380±8.1; LS20 = 406±13.2; NS = 435±6.1, LS10 = 461±12.9). No difference was found in water and food intake among the groups. Also, no differences were observed in the litter size among experimental groups and no correlation betweenthe number of pups and maternal body weight at the 3rd week of gestation. At birth, body weight (g, n=14 to 27/group) (M: NS = 6.5±0.1, LS = 5.5±0.1, LS10 = 6.1±0.1, LS20 =4.8±0.1,F:NS = 6.1±0.2, LS = 5.2±0.1, LS10 = 5.6±0.1, LS20 = 4.1±0.1) and naso-anal length (cm, n=14 to 27) (M: NS = 5.1±0.02, LS = 4.9±0.03, LS10 = 5.0±0.03, LS20 = 4.6±0.03, F: NS =4.9±0.05,LS = 4.8±0.04, LS10 = 4.9±0.03, LS20 = 4.4±0.03) were lower in LS and LS20 than in NS offspring. Conclusion: Although maternal dietary intake was not influenced by dietary sodium content, maternal low sodium diet during the second half of gestation induced lower birth weight and size.conferenceObject Newborn cardiac structural alterations in response to salt restriction or overload during pregnancy(2016) SERAVALLI, Priscila; ZAGO, Breno Calazans; OLIVEIRA, Ivone Braga de; VERAS, Mariana Matera; HEIMANN, Joel
