Abstract

Objectives: The aim of this study was to investigate the effects of repetitive agmatine administration on sensorimotor gating in rats first but, as unexpected, ulcerative necrotic cutaneous lesions appeared, thus, the study was directed primarily to clarify these results. Materials and Methods: In the first set of experiments, we administered agmatine (40, 80 and 160 mg/kg) and saline (control group) subcutaneously to male Wistar albino rats (n=8 for each group) for 14 consecutive days. Ulcerative necrotic cutaneous lesions appeared following the third day of agmatine administration. We decided to explore the potential toxic dermal effects of agmatine and conducted second set of experiments with two groups (n=8) to compare the effects of subcutaneous vs. intraperitoneal agmatine (80 mg/kg) injection to understand if the injection route determines the toxicity. Results: Our results showed that prolonged subcutaneous but not intraperitoneal administration of agmatine leads to a delayed dermal reaction in rats. Histopathologic examination of skin samples revealed cutaneous aseptic necrosis at the injection site whereas blood tests were found to be normal. Conclusion: This finding is important to point out the risks of prolonged subcutaneous administration of agmatine to rats within the concept of animal welfare. In addition, the results raise questions about the possible risks of over-the-counter use of agmatine among humans although the agent is taken via oral route.

Özet

Amaç: Bu çalışmanın amacı sıçanlarda ilk kez tekrarlayan agmatin uygulamasının sensorimotor kapılama sistemi üzerine etkilerini incelemekti, ancak subkütan uygulamada karşımıza çıkan beklenmedik ülseratif nekrotik lezyonlar bu konuya odaklanmamıza neden oldu. Gereç ve Yöntemler: İlk grup deneylerde, erkek Wistar albino sıçanlara 14 gün süreyle subkütan yoldan agmatin (40, 80 ve 160 mg/kg) veya salin (kontrol grubu) enjeksiyonu yapıldı (n=8 her bir grup). Uygulamaların üçüncü gününden itibaren agmatin verilen gruplarda ülseratif nekrotik deri lezyonları gözlendi. Bu etkilerin dermal bir reaksiyona bağlı olup olmadığını anlamak için ayrı bir denek grubuna aynı protokolle agmatin (80 mg/kg) intraperitoneal yoldan verildi (n=8 her bir grup). Bulgular: Bulgularımız subkütan yoldan verilen agmatinin geç dönemde ortaya çıkan bir dermal reaksiyona neden olurken, intraperitoneal uygulamanın böyle bir etki oluşturmadığına işaret etti. Lezyon gözlenen deneklerden alınan deri örneklerinin histopatolojik incelemesinde, enjeksiyon yerindeki deride aseptik nekroz saptanırken, bu deneklerin kan testleri normal bulundu. Sonuç: Bu bulgu sıçanlarda uzun süreli subkütan agmatin uygulamasının denek refahı bakımından risk oluşturan toksik bir etkiye neden olduğuna işaret etmektedir. Bu bulgu insanlarda oral yoldan reçetesiz olarak alınabilen agmatinin bazı potansiyel riskleri olabileceği konusunda sorular ortaya çıkarmaktadır.
