Background: Exposure to different frequencies would have a profound effect on the brain tissue extract supernatant’s optical density and hexakis-2-methoxyisobutylisonitrile (99mTc-MIBI) build-up. Objectives: This study aimed to investigate the blood-brain barrier permeability after electromagnetic field irradiation. Methods: In this study, 150 male albino rats were randomly divided into 25 groups. They had an intraperitoneal injection of Evans blue 24 hours before experiments. Before 15 or 30-min Electromagnetic Field (EMF) irradiation (900, 1700, and 1900 MHz), 500 μCi (18.5 MBq) of 99mTc -MIBI was injected via the caudal vein. The rats decapitated 15, 30, 45, or 60 min after radiotracer injection to evaluate the brain-specific activity and brain tissue extract supernatant’s optical density. Results: No significant difference was found between the groups in 60-min post-injection activity after 15-min EMF radiation at 900, 1700, and 1900 MHz. The brain-specific activity with 30-min EMF radiation showed a significant increase in the 900 MHz group compared to others. Brain/whole body-specific activity in all experimental groups after 15-min EMF radiation showed no significant differences. On the other hand, the brain/whole body-specific activity ratio with 30-min EMF radiation showed a significant increase in the 900 MHz group compared to other groups. A comparison between the brain tissue extract supernatant’s optical density in the experimental groups after 15 and 30-min EMF radiation showed no significant difference in Evans blue accumulations in brains. Conclusions: It may be concluded that mobile phone electromagnetic field radiation may increase the blood-brain barrier permeability. As most humans use mobile phones for daily communications, all users around the world need to be advised of the effects of modern call devices.

Purpose: The purpose of this study was to analyze the effects of estrogen deficiency and hormone replacement therapy (HRT) on fibrinolytic activity in a rat mode of surgically-induced menopause. Methods: Twelve-week-old, sexually mature female Sprague-Dawley rats, each weighing 200–250 g, were randomly divided into four groups: (1) sham-operated group, (2) ovariectomy group, (3) ovariectomy group followed by oral administration of daily 17β-estradiol (0.02 mg/kg/day) (E2) + norethisterone acetate (0.01 mg/kg/day), and (4) ovariectomy group followed by oral administration of daily 17β-estradiol (0.01 mg/kg/day) + drospirenone (0.02 mg/kg/day). Tissue plasminogen activator (tPA) antigen, plasminogen activator inhibitor-1 (PAI-1) antigen, and PAI-1/tPA levels were measured as markers of fibrinolysis in plasma and liver and brain tissue. Results: Compared with sham-operated rats, ovariectomized rats showed higher levels of fibrinolytic activity; however, the increased fibrinolytic activity in plasma and liver tissue was significantly reduced by HRT regimens. No change was observed in the levels of fibrinolytic activity in brain tissue. Conclusions: HRT showed beneficial effects by decreasing fibrinolytic activity related to surgically-induced menopause. Short-term HRT treatment was associated with a shift in the procoagulant-anticoagulant balance toward a procoagulant state.
