Abstract

In this study, we aimed to investigate the effects of long-term ketamine upon testis germ cells and the regionaldistributions of calcineurin immunopositive testis germ cells in adult male rats. Thirty adult male, Sprague-Dawley rats weredivided into one control and four treatment groups, with 6 rats in each. Rats in treatment groups of 1, 2, 3 and 4 receivedketamine at doses of 40, 60, 80 and 100 mg/kg intraperiotenal (i.p.), respectively, while those in group 5 (as control)received i.p. 0.9 % NaCl. In this study, we observed degeneration in germ cells and oedema in testis connective tissue.However, we determined that ketamine remained in tissue for a long term and high-dose resulted in a decrease in thenumbers of germ cells and Leydig cells. However, there were varying degrees, from (+) to (+++), of calcineurin immunoreac- tivity in testicular tissue sections stained with immunohistochemical methods. The results suggest that long-term use ofhigh-dose ketamine may cause male infertility due to histopathological and immunohistochemical changes in testicularinterstitial tissues, as well as changes in sperm density and germ cell number.

Özet

Bu çalışmada, sıçanlara uygulanan uzun süreli ketaminin testis germ hücreleri ve kalsinörin immunopozitif hücrelerüzerine etkilerinin araştırılması amaçlandı. Otuz adet, yetişkin Sprague-Dawley erkek sıçan her grupta 6’şar adet olacakşekilde 5 gruba ayrıldı. On dört gün süreyle ve günde iki defa olmak üzere, grup 1, 2, 3 ve 4’e sırasıyla 40, 60, 80 ve 100mg/kg ketamin hidroklorid ve grup 5’e ise sadece % 0,9 NaCl intraperitonal (i.p.) olarak uygulandı. Bu çalışmada, ketaminuygulanan gruplarda testis bağ dokusunda ödem ve germ hücrelerinde dejenerasyonlar gözlendi. Grup 3 ve 4’te, tubulusseminiferus lumenlerinde sperm miktarındaki azalmanın grup 1 ve 2’ye göre daha fazla olduğu belirlendi. Uzun süreli veyüksek doz ketamin kullanımının bir sonucu olarak, spermatogenetik germ hücreleri ve Leydig hücreleri miktarında daazalma olduğu tespit edildi. Ayrıca, immunhistokimyasal yöntemler ile boyanmış testis dokusu kesitlerinde, kalsinörin’indeğişik derecelerde, (+)’dan (+++)’a kadar, immunoreaktivite verdiği gözlendi. Sonuç olarak, uzun süreli ve yüksek dozketamin kullanımının testis intersitisyel dokularında, sperm yoğunluğunda ve germ hücre miktarlarında histopatolojik veimmunohistokimyasal değişiklikler yapabileceği belirlenmiş oldu. Ayrıca, uzun süreli ketamin infüzyonunun erkekinfertilitesine neden olabileceği de düşünülmektedir.
