Abstract

Purpose: Flaxseed (Linum usitatissimum L.) is a widely consumed functional food rich in omega-3 fatty acids, lignans, and fiber. However, due to its cyanogenic glycoside content, excessive consumption may lead to toxic effects. This study aimed to evaluate the histopathological effects of high-dose oral flaxseed administration on rat lung tissue. Materials and Methods: Thirty-two adult female Wistar Albino rats were randomly divided into four groups (n=8 each): Control, Low Dose (1.4 g/kg/day), Medium Dose (2.8 g/kg/day), and High Dose (5.6 g/kg/day). Flaxseed was administered via oral gavage for seven days. At the end of the experiment, the rats were sacrificed under anesthesia. Lung tissues were fixed in 10% neutral for-malin, stained with H&E, and examined under light microscopy Results: No pathological changes were observed in the control and low-dose groups. In the medium-dose group, vascular congestion was noted. The high-dose group exhibited vascular congestion, mononuclear cell infiltration, and interalveolar septal thickening. These findings indicate that flaxseed administration induces dose-dependent inflammatory and structural alterations in lung tissue Conclusion: Short-term high-dose flaxseed intake causes significant histopathological changes in rat lung tissue. Findings such as vascular congestion, inflammatory infiltration, and septal thickening suggest potential pulmonary toxicity. The absence of similar findings at lower doses supports a dose-dependent relationship. These results emphasize the need for cautious use of functional herbal products and encourage further biochemical and molecular studies to elucidate underlying mechanisms.

Özet

Amaç: Keten tohumu (Linum usitatissimum L.), omega-3 yağ asitleri, lignanlar ve lif bakımından zengin olması nedeniyle yaygın tüketilen fonksiyonel bir gıdadır. Ancak içerdiği siyanojenik glikozitler nedeniyle aşırı tüketimi toksik etkilere yol açabilir. Bu çalışmada, yüksek doz oral keten tohumu uygulamasının rat akciğer dokusunda oluşturduğu histopatolojik etkiler değerlendirildi. Araçlar ve Yöntem: 32 erişkin dişi Wistar Albino rat, sekizerli dört gruba ayrıldı: Kontrol, Düşük Doz (1.4 g/kg/gün), Orta Doz (2.8 g/kg/gün) ve Yüksek Doz (5.6 g/kg/gün). Keten tohumu oral gavaj yoluyla 7 gün boyunca uygulandı. Deney sonunda akciğer dokuları çıkarılarak %10 nötral formalinle tespit edildi, H-E ile boyandı ve ışık mikroskobunda değerlendirildi. Bulgular: Kontrol ve düşük doz gruplarında patolojik bulgu saptanmadı. Orta doz grubunda vasküler konjesyon izlenirken, yüksek doz grubunda vasküler konjesyonla birlikte mononükleer hücre infiltrasyonu ve interalveolar septum kalınlaşması görüldü. Bulgular, keten tohumunun doza bağlı olarak akciğer dokusunda inflamasyon ve yapısal değişikliklere yol açabileceğini göstermektedir. Sonuç: Yüksek dozda kısa süreli keten tohumu alımı, rat akciğer dokusunda belirgin histopatolojik değişikliklere neden olmuştur. Bulgular, keten tohumunun yüksek dozlarda potansiyel pulmoner toksisite riski taşıdığını göstermektedir. Bitkisel içerikli fonksiyo-nel gıdaların aşırı tüketimi konusunda dikkatli olunmalı; ileri biyokimyasal ve moleküler çalışmalarla mekanizmalar aydınlatılmalıdır.
