Background: The increase of stress following the technological improvements appears to be an important factor that causes organs disorders like genital system. Therefore the present study was conducted to investigate the effects of chronic multiple sequential stress on rat epididim. Materials and Methods: 18 Wistar rats were divided randomly into two equal groups. In animals under stress, the m...
Background: The increase of stress following the technological improvements appears to be an important factor that causes organs disorders like genital system. Therefore the present study was conducted to investigate the effects of chronic multiple sequential stress on rat prostate. Materials and Methods: 18 Wistar rats were divided randomly into two equal groups. In animals under stress, the m...
Abstract Introduction: Chronic heterogeneous stress may be better for evaluation of the effect of chronic stress situations on the nociceptive behaviour. The present study investigated the effects of chronic heterogeneous sequential stress on thermal-induced nociception and formalin induced pain behavior in rats. Methods: In the present study, adult rats (220-300 g) were used. Animals were ...
results the mean number and size of betz cells in the stressed group decreased significantly compared to those in the control group (p < 0.05). qualitative observations revealed chromatolysis of nissl bodies, nucleus condensation, and a decrease in neural processes. the mean number of apoptotic cells in the stressed group were also significantly increased compared to that of the control group (...
Background and Aim: Stress increasing which is a consequence of technological development can complicate the function of body organs and tissues. Regarding the role of the cerebellum in harmonizing physical movements, the present study was conducted to assess the effects of chronic stress on cerebella cortex of rats. Materials and Methods: Eighteen Wistar rats were randomly divided into two equ...
multiple sclerosis (ms) is the most prevalent disease caused by the inflammatory demyelinating process that causes progressive nervous system degeneration over the time. optical coherence tomography (oct) is a non-invasive optical imaging technology, which can measure the thickness of retinal nerve fiber layer as well as the diameter of the macula. the purpose of the study is evaluation oct fin...
Introduction : Multiple Sclerosis (MS) is one of the most common chronic diseases of the Central Nervous System . Of it's significant features is that most patients are young adults and it's disabling nature. Psychiatric disorders such as anxiety and stress are seen in MS patients considerably. Journaling the nursing intervention and written emotional expression, is one of cost-effective self...
In this paper, two-stage and purely sequential estimation procedures are considered to construct fixed-width confidence intervals for the reliability parameter under the stress-strength model when the stress and strength are independent exponential random variables with different scale parameters. The exact distribution of the stopping rule under the purely sequential procedure is approximated ...
Abstract Objectives: training immunization against stress, reducing stress most people with chronic diseases, have a positive impact, but this intervention so far not been done in MS patients. The purpose of this study was to investigate impact training immunization against stress, to reduce rate depression in pat. Tools and Methods: Statistical population this study, patients Multiple...
Multiple risk factors are known to exist that will attack cells at various parts of the body eliciting new inflammation sites hence new inflammatory diseases. Acute inflammation usually takes place first in response to the attack of the risk factor (s). As soon as the risk factor (s) is removed, the acute inflammatory response will stop. Conceivably, acute inflammation does not lead to oxidativ...
