Abstract

Protective effects of vitamin E on cisplatin nephrotoxicity: a light and electron microscopic study Purpose: In this study, it is aimed to investigate the protective effects of vitamin E on cisplatin nephrotoxicity in a morphological level. Methods: In the study, 18 male albino Wistar rats were divided into 3 groups. During a three-month period, while control group subjects were administered physiological serum by intramuscular (im) injection everyday, group II and III subjects were given intravenous (iv) 5 mg/kg of cisplatin once in a month. Besides, group III subjects were administered intramuscular (im) 5 mg/kg of vitamin Eeveryday following the first cisplatin injection. At the end of the experiment, a sample of kidney cortex for biopsy was taken and it was examined by the light and electron microscope levels. Results: It was observed that the kidney tissue was normal in control group subjects. In cisplatin group, it was noticed that most of the renal corpuscle lost their normal appereance and size; glomerular structure disappeared partially or in total. It was seen that some renal corpuscle disappeared and these areas were filled with infiltration cells. Tubular dilation and tubular damages were observed especially in the corticomedullary area. Proximal tubular degenerations were thickening of basement membrane, loss of brush border, vacuolization, swollen of mitochondria in the proximal tubule epithelial cells. In addition, infiltration foci was observed in intersitisyel connective tissue. In the group which was cisplatin plus vitamin E was observed that the morphologic damages and morphometric changes were decreased, on the contrary, infiltration focuses began to diminish, but they could be still observed partially. Conclusion: In this study, in the prevention of nephrotoxicity, which is caused by cisplation injection to rats, it was observed that long-term vitamin E treatment was effective morphologically. Under the light of this knowledge, we think that cisplatin chemotherapy accompanying with vitamin E would be beneficial clinically.

Özet

Bu çalışmada, cisplatin nefrotoksisitesinde E vitamininin koruyucu etkisinin bulunup bulunmadığının morfolojik düzeyde incelenmesi amaçlandı. Gereç ve Yöntem: Çalışmada, 18 adet erkek Wistar albino sıçan 3 gruba ayrıldı. Kontrol grubu deneklerine üç ay boyunca her gün intramusküler (im) yolla serum fizyolojik verilirken, II. ve III. grup deneklerine ise üç ay boyunca, ayda bir kez 5 mg/kg cisplatin intravenöz (iv) yolla uygulandı. III. grup deneklere ayrıca, ilk cisplatin enjeksiyonunu takiben deney boyunca her gün 5 mg/kg E vitamini im yolla verildi. Çalışmanın sonunda, tüm deneklerin böbrek korteks nekropsi materyalleri alınarak ışık ve elektron mikroskopik düzeyde incelendi. Bulgular: Kontrol grubu deneklerde; böbrek dokusunun normal yapıda olduğu gözlendi. Cisplatin grubunda ise bir çok böbrek cisimciğinin normal görünüm ve büyüklüğünü kaybetmiş olduğu, bazılarının ortadan kaybolduğu ve bu alanlara lenfositlerin infiltre olduğu görüldü. Ayrıca glomerüler yapının ise kısmen veya tamamen ortadan kalktığı dikkati çekti. Özellikle, kor-tikomedüller bölgede olmak üzere, tübüler genişlemelere ve tübüler hasarlara rastlandı. Proksimal tübül dejenerasyonları; bazal membran kalınlaşması, prizmatik hücre fırçamsı kenarlarında bozulma, vakuolizasyon, mitokondride şişme şeklinde olup, intersitisyel bağ dokuda da bir çok infiltrasyon sahası gözlendi. E vitamini ile tedavi edilen grupta morfolojik hasarların ve morfometrik değişikliklerin azaldığı buna karşın infiltrasyon odaklarının azalmakla birlikte yer yer varlığını sürdürdüğü dikkati çekti.Sonuç: Bu çalışmada, sıçanlarda cisplatin enjeksiyonları ile oluşturulan nefrotoksisitenin önlenmesinde, uzun süreli E vitamini tedavisinin morfolojik açıdan etkili olduğunu gördük. Bu bilgiler ışığında cisplatin kemoterapisi esnasında tedaviye E vitamini eklenmesinin klinik açıdan fayda sağlayacağı kanısındayız.
