Radio waves, such as cordless phones and wireless modems, have increased significantly. This study aimed to measure the effects of the 2.45 GHz wave on a mice's immune system's blood markers.
Seventy-two male mice were used. Mice’s were divided into one control group and two radiation-exposed groups (A and B). Then, there were two Wi-Fi modems, one plain and without an antenna, for group a mouse contact. The other was the type with two antennas; the mice in group B were brought into contact. After exposure, blood samples regarding white blood cells, monocytes, lymphocytes, and neutrophils were analyzed.
White blood cells, monocytes, lymphocytes, and neutrophils increased in the control group (P<0.001). However, these parameters significantly declined over time in the two intervention groups (P<0.001). The blood parameters of the mice in the two intervention groups exposed to various modems were similar (P>0.05).
The results indicated the interference of waves of this spectrum, mainly radio frequency, with the immune system of exposed mice. Blood cells are more susceptible to long-term exposure to Wi-Fi waves and have a downward trend in terms of number. Also, no significant difference was observed between the blood parameters of the two groups with different modems.

Idiopathic thrombocytopenic purpura (autoimmune), the most common cause of acute onset of thrombocytopenia in children who are otherwise healthy. This study was conducted with the aim of investigating the factors affecting the response to treatment in hospitalized children.

This retrospective study was conducted by examining the files of patients hospitalized due to ITP in Hazrat Masoumeh (S) Hospital from April 2009 to March 2019. The criteria for inclusion in the study included confirming the diagnosis of ITP and the age of 1 month to 14 years, and the exclusion criteria included cases of discharge with personal consent and not completing the patient's treatment course, the presence of pancytopenia or bicytopenia, the presence of moderate or severe splenomegaly or severe in clinical examinations, BMA based on the presence of a diagnosis other than ITP, not receiving any of the ITP treatment protocols, and patients whose first visit with the diagnosis of ITP was in another center or city. The information about age, sex, clinical symptoms on arrival, initial platelets and the platelets of days 3, 5, 14 and 180 were extracted from the patients' files. The type of treatment protocol, the need to repeat the treatment, the recurrence of the disease and the major complications of the treatment were extracted from the patients' files and finally the data were analyzed with SPSS software.

The response to the treatment on different days was unrelated to the age, gender, and initial platelets (except for one exception) (P>0.05). In relation to clinical symptoms, the response to treatment on days three and five was related to the clinical symptoms at the time of presentation and on days 14 and 180 it was unrelated. Response to treatment on days 3 and 5 in different treatment protocols had a significant relationship (P<0.05), but there was no significant difference on days 14 and 180.

The best response was in the combined treatment group with methylprednisolone and IVIg, and the lowest response to treatment was observed in those receiving methylprednisolone alone.

The widespread use of electromagnetic waves in communication has led to the consideration of their biological effects. According to valid scientific findings, these waves can entail changes in the cell function, there by causing or accelerating some diseases.

Since the amount of liver enzymes in the blood can be a sign of liver damage, this study was performed to evaluate these enzymes.

This experiment was done on 120 six-month-old pigeons. After adaptation to laboratory settings, they were divided into six random groups of distance from BTS and daily exposure time. G1: 50 cm/30 minutes, G2:100 cm/30 minutes, G3: 150 cm/30 minutes, G4: 50 cm/60 minutes, G5:100 cm/60 minutes, and G6:150 cm/60 minutes.Each group was exposed to waves for one month daily and blood tests were measured to determine the amount of liver enzymes before and one month after exposure; the results were processed by SPSS software.

The findings of this study revealed a statistically significant relationship between BTS waves and liver damage after the increase in the level of liver enzymes in all six groups. Therefore, it is safe to assume that electromagnetic waves, depending on the frequency, energy, duration and distance, can have destructive effects on body tissues, including the liver. The mean changes of ALP and ALT were the highest and the lowest, respectively. Also, the most changes in liver enzymes occurred in the first and fourth groups, which had the shortest distance to the wave source.

Increasing the exposure time and reducing the distance to the wave source changed the amount of liver enzymes. This study showed that "distance to the source of wave propagation" was more important than "exposure time".

In recent years, the use of radio waves and devices operating in the 2.45 GHz range, such as cordless telephones and wireless modems, has greatly increased. The aim of this study was to determine the effect of 2.45 GHz waves on hematological markers of the immune system in mice.

In this experimental study, 72 immature male BALB/C mice were used. Mice were divided into 3 groups; one control group and two groups exposed to radiation (group A and group B). Then two Wi-Fi modems were prepared, one simple and without antenna that mice of Group A were exposed to it and the second type had two antennas that mice of Group B were exposed to it. After exposure, blood samples were taken to measure the white blood cells, monocytes, lymphocytes, and neutrophils.

The number of white blood cells, monocytes, lymphocytes, and neutrophils increased during the study in control mice, but these parameters decreased significantly in the mice of the two intervention groups, which was time-dependent. There was no significant difference between the blood parameters of mice in the two intervention groups exposed to different modems.

The current findings indicate the side effects of 2.45 GHz on the immune system of exposed mice. This showed that white blood cells are more effective against long-term exposure to Wi-Fi waves.

There are studies that support music and singing as appropriate developmental care for premature infants, thus, we conducted this study to investigate the physiological and behavioral responses of premature infants to Quran recitation, lullaby music and silence.
In a randomized controlled trial (2011-2012),120 premature infants in the Neonatal Unit (NNU) at Izadi Hospital, were randomly assigned to experimental (holy Quran recitation, lullaby music and silence) and control groups. The four groups were surveyed for physiological responses including, oxygen saturation, respiratory rate and heart rate and behavioral states. The data were analyzed using SPSS-PC software and quantitative tests.
66females and 54 male infants with gestational age 28- 36 weeks entered into the study. The fourgroupswere not significantly different in terms of demographic variables (P>0.05). The comparisonofchangesinthe infant’s responsesintheendof the intervention comparedtothebase lines, showedno statistically significant differencesbetweengroups(P>0.05). Repeated measures ANOVA and Friedman test did notindicate any significant differences in the mean ofresponseswithinanyof the four groups during the courseof study (P>0.05).
Although fluctuations were observed in the mean of physiological responses and behavioral states in premature infants who listened to the recitation of the holy Quran and lullaby music, but these fluctuations were not significant. Findings of this study demonstrated that the preterm infants did not display any adverse reactions to the carefully designed acoustic intervention.
