Introduction: Amongst the medications to reduce pain, morphine as an important natural and tramadol as an important synthetic drug have been mostly considered. There are few studies on the comparison of the analgesic effect of these drugs in neonatal and perpubertal periods. Methods: Neonate rats (n=49) were randomly divided into three groups. On postnatal days 8-14, one group received s...
OBJECTIVE The purpose of this study was to examine the association between pre and post environmental tobacco smoke (ETS) exposure and behavioral problems in schoolchildren. METHODS In the cross-sectional 6 cities Study conducted in France, 5221 primary school children were investigated. Pre- and postnatal exposure to secondhand tobacco smoke at home was assessed using a parent questionnaire....
Perinatal sulfur dioxide exposure disrupts parasympathetic regulation of cardiovascular activity. Here, we examine the relative risks of prenatal versus postnatal exposure to the air pollutant and the reversibility of the cardiovascular effects. Two groups of animals were used for this study. For prenatal exposure, pregnant Sprague-Dawley dams were exposed to 5 parts per million sulfur dioxide ...
Maternal exposure to polystyrene nanoplastics impact postnatal brain development in mouse offspring. This work motivates further studies determine the levels of environment.
Although the brain continues developing in the postnatal period, epidemiological studies on the effects of postnatal exposure to neurotoxic POPs through breast-feeding remain mostly inconclusive. Failure to detect associations between postnatal exposure and health outcomes may stem from the limitations of commonly employed approaches to assess lactational exposure. The aim of the present study ...
BACKGROUND The effects on postnatal growth of maternal exposure to low levels of lead during pregnancy have not been well established. In addition, information is limited regarding the protective effect of dietary calcium intake during pregnancy against the effect of lead for fetal and postnatal growth. We investigated the relationship between prenatal exposure to lead and growth at birth and 6...
The goal of this epidemiologic investigation was to analyze the associations between prenatal and postnatal exposure to airborne polycyclic aromatic hydrocarbons (PAH) and severity of wheeze and recurrent wheeze. The 257 children included in this analysis had a complete set of prenatal and postnatal PAH measurements and attended regular health checkups over a 4-year follow-up period since birth...
BACKGROUND Infant exposure to persistent organic pollutants (POPs) may contribute to obesity. However, many studies so far have been small, focused on transplacental exposure, used an inappropriate measure to assess postnatal exposure through breastfeeding if any, or did not discern between prenatal and postnatal effects. OBJECTIVES We investigated prenatal and postnatal exposure to POPs and ...
Background: It is demonstrated that morphine and tramadol affects seizure but the mode of action of these drugs on seizure has not been compared yet with increasing of age. The aim of this study was to compare the impact of exposure to these drugs on Pentylenetetrazol-induced seizure in immature rat.Methods: Male neonate rats were randomly chosen and divided into three groups namely Saline (n=2...
