The relationship between stress, restraint, and eating has been studied using various methods, including retrospective self-reports of stress and eating that are open to inaccuracies. Additionally, laboratory research has not systematically varied the fat content and sweetness of food items to assess how stress relates to specific food preferences. In this study of 40 women we examined the role...

The present study was designed to investigate the effect of Thymoquinone (TQ) in restraint stressinduced biochemical alterations in Wistar albino rats. Restraint stress was applied for 21 days (4 h/day) and 60 min before every stress exposure the rats were treated with two doses of TQ (5 and 10 mg/kg). In serum, Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Interleukin-1β (I...

BACKGROUND Cognitive dietary restraint (perceived ongoing effort to limit dietary intake to manage body weight) is common in women at all life stages. In young women, high dietary restraint has been associated with both increased excretion of cortisol (a stress hormone) and reduced bone mass. Whether this occurs in older women is unknown and is reported here for the first time. METHODS Postme...

Five experiments studied the modulation of acute opiate withdrawal by restraint stress. Rats were subjected to a 2-hr restraint stress, and 1, 3, or 7 days later they received a single injection of morphine followed by injection of naloxone. Naloxone precipitated a withdrawal syndrome. This syndrome was enhanced when it occurred 1 day after stress but was reduced when it occurred 7 days after s...

Cannabis resin (CI) produced a dose-related increase in rat brain serotonin concentrations, whereas restraint stress produced maximal rise of the neurotransmitter concentrations at 1 h, followed by a tendency to normalise by 4 h. The prostaglandin (PG) synthesis inhibitors, diclofenac and paracetamol, antagonized CI and restraint stress induced rise in serotonin concentrations. The findings len...

We have shown previously that chronic restraint stress causes atrophy of apical dendrites and alterations in the spine density of CA3 hippocampal neurons in rats. In the present study, the effect of 45 days of rehabilitation following 21 days of restraint stress on the dendritic morphology of CA3 neurons of the hippocampus was carried out. The results revealed that 45 days of rehabilitation rev...

We found retardation of preimplantation embryo growth after exposure to maternal restraint stress during the preimplantation period in our previous study. In the present study, we evaluated the impact of preimplantation maternal restraint stress on the distribution of inner cell mass (ICM) and trophectoderm (TE) cells in mouse blastocysts, and its possible effect on physiological development of...

Silymarin is a flavonoid extracted from the milk thistle Silybum marianum. It has been reported to prevent liver injuries induced by various chemicals or toxins. Our recent study suggested that silymarin induces hepatic synthesis of glutathione by increasing cysteine availability, which may consequently contribute to increased antioxidant capacity of the liver. In the present study, we investig...

To clarify the role of metallothionein (MT), an antistress protein, induced by psychological stress, we carried out an experiment to determine whether hepatic MT synthesis induced by restraint stress can be classically conditioned by an olfactory odor cue of camphor. Mice were conditioned by exposure to the odor of camphor 1 hr before restraint stress and partly during restraint stress. Althoug...

Introduction: Stress has many effects on the development of systems and organs in the fetal period, and these effects appear after birth. Since hemopoietic system is susceptible to stress, effects of restraint stress were studied in offspring of pregnant rats. Methods: Pregnant rats were divided into one control and three stress groups. The control group did not receive any stress during the ge...
