2.45 gigahertz elektromanyetik radyasyonun böbrekteki histopatolojik etkileri ve C vitamininin koruyucu etkisi

Abstract

Amaçlar: Elektromanyetik radyasyonun (EMR) sıçan böbreğinde yol açtığı histopatolojik hasarı ve C vitamininin (askorbik asit) oluşan bu renal hasara karşı iyileştirici etkilerini araştırmak.

Gereç ve Yöntemler: On sekiz dişi Sprague-Dawley sıçanı, her biri altı sıçan olmak üzere üç gruba ayrıldı. Grup 1 şam grubuydu; bu sıçanlar herhangi bir stres veya elektromanyetik radyasyona maruz kalmadan kafeslerinde tutuldu. Grup 2, 30 gün boyunca 2.45 gigahertz elektromanyetik radyasyona maruz bırakıldı. Grup 3 de 30 gün boyunca (günde 1 saat) 2.45 gigahertz elektromanyetik radyasyona maruz bırakıldı, ancak ilk maruziyetinden 24 saat önce ve deney boyunca her gün C vitamini verildi. Tüm sıçanlara histopatolojik inceleme için nefrektomi yapıldı.

Bulgular: Şam grubunda herhangi bir patolojik değişiklik olmadı. Grup 2’de tübüler ve glomerüler hasarı içeren önemli patolojik değişiklikler izlendi (P<0.05). İnterstisyel ve vasküler hasar açısından grup 2 ve 3’te önemli bir değişiklik izlenmedi (P>0.05). Tübüler ve glomerüler hasar grup 3’te grup 2’ye göre daha az şiddetliydi (P<0.05). Şam grubu ve grup 3 arasında tübüler, glomerüler, interstisyel ve vasküler hasar açısından önemli bir farklılık izlenmedi (P>0.05).

Sonuç: Elektromanyetik radyasyonun böbrekte yol açtığı tübüler ve glomerüler hasar, elektromanyetik radyasyon maruziyeti öncesi alınan C vitamini ile neredeyse tamamen normale dönmektedir.

Histopathological Effects of 2.45 Gigahertz Electromagnetic Radiation on the Kidney, and Protective Effects of Vitamin C

Abstract

Objectives: To investigate the effects of electromagnetic radiation (EMR) on the kidneys based on histopathological changes of renal damage, and to investigate the ameliorating effects of vitamin C (ascorbic acid) against EMR-induced renal damage in rats.

Materials and Methods: Eighteen female Sprague-Dawley rats were divided into three groups of six rats each. Group 1 was the sham group; these rats were kept in their cages without stress or electromagnetic radiation exposure. Group 2 was exposed to 2.45 gigahertz electromagnetic radiation for 30 days. Group 3 was also exposed to 2.45 gigahertz electromagnetic radiation for 30 days (1 h/day) but received vitamin C 24 hours prior to the first exposure and daily throughout the experiment. All rats underwent nephrectomy with histopathological examination.

Results: There were no pathological findings in the sham group. Significant pathological changes were observed in group 2, including tubular and glomerular damage (P<0.05). Interstitial and vascular damage was not significantly different between groups 2 and 3 (P>0.05). Tubular and glomerular damage was less severe in group 3 than in group 2 (P<0.05). There was no significant difference between the sham group and group 3 in terms of tubular, glomerular, interstitial, or vascular damage (P>0.05).

Conclusion: Electromagnetic radiation-induced tubular and glomerular damage in the kidney was almost completely reversed with the administration of vitamin C before electromagnetic radiation exposure.
