Background: Measurement of mean arterial blood pressure is better predictive factor for pregnancy-induced hypertension than measurement of the systolic and diastolic blood pressure or systolic blood pressure. According to the theory of “protective effect of fish oil supplementation on pregnancy-induced hypertension “and the importance of blood pressure control in pregnancy, the present study was conducted to investigate the effect of fish oil supplementation in pregnancy on mean arterial blood pressure. Materials and Methods: In this clinical trial study, 120 healthy pregnant women were randomly divided into two groups of 60 persons. Same prenatal care was performed for both groups and the intervention group was received Salmon fish oil capsule 1000 mg/day, from 16th week to the end of the pregnancy. Systolic and diastolic blood pressure were measured in both groups once every four weeks up to 28th week, every 2 weeks from 28th till 36th week and once every week up to the end of pregnancy. Mean arterial blood pressure was calculated and all gathering data was analyzed with T test and Mann-Whitney test. Results: Mean arterial blood pressure in the intervention and control group was 80.76±5.50 and 78.46±4.50 mmHg which was not significantly different (p>0.05). Conclusion: The results showed that adding fish oil supplements to the diet of pregnant mothers had no significant effect on mean arterial blood pressure.

Abstract

Background: The aim of this study was to investigate the effect of fed fish oil (FO) with or without vitamin E for mothers on the testis cells of male offsprings.

Materials and Methods: Sixty mature female NMRI mice were divided into different groups: control (CTR; Standard diet(vitamin E 50 mg IU/kg) pre and postnatal period); I) Gavages 0.01 ml/day/mother fish oil (FO)+CTR diet during prenatal period; II) Gavages FO+CTR diet during postnatal period; III) consumed VITE(125 mg IU/kg) 2.5 folded greater than standard recommendations(2×)during prenatal period; IV)consumed VITE(2×)diet during pre and postnatal period; V)consumed VITE(2×)diet during postnatal period; VI) Gavages FO+VITE(2×) diet during prenatal period; VII) Gavage FO+VITE(2×)diet during postnatal period ;VIII) Gavages FO+VITE (2×)diet during pre and postnatal period. After weaning, the testes were collected and histological data were analyzed using SAS software by Duncan test.

Results: testes cells length, width and weight was lower in offspring which their mothers fed FO+CTR diet during prenatal, (p<0.05).Vitamin E consumption during postnatal period improved these parameters (p<0.05). Spermatogoni (47 vs. 43), spermatocyte (43 vs. 34), Spermatid (63 vs. 44), Sertoli (0.9 vs. 2), and Leydig (3 vs. 1.7) were increased as FO+VITE was used than CTR (p<0.05).

Conclusion: The positive effects of supplementation maternal diet by FO with VITE or sole VITE was observed. Thus, antioxidants should be consumed along with omega-3 fatty acids in maternal diet.
