Deneysel Periferik Sinir Hasarında Kateşin Etkisinin Biyokimyasal ve Histopatolojik Olarak İncelenmesi

Öz:
AMAÇ: Kateşinler polifenol grubundan olup başlıca kateşin, epikateşin, epigallokateşin, epigallokateşingallat (EGKG) gibi alt grup maddeler içermektedir. Çalışmada kateşinin temel metaboliti olan EGKG'ın, periferik sinir hasarı yapılmış sıçanlardaki etkisinin gösterilmesi amaçlanmıştır.yÖNTEM ve GErEÇLEr: Toplam 74 Albino-Wistar cinsi rat kontrol, travma, serum fizylojik (SF), 25 mg/kg, 50 mg/kg ve günlük tüketim ( travma öncesi 14 gün boyunca intraperitoneal 10 mg/kg EGKG verildi) EGKG grupları olmak üzere 6 gruba ayrıldı. İlk grup hariç diğer gruplarda siyatik sinire 50 gr/cm2 basıncı ile kapanan klip ile 1 dakika kompresyon hasarı yapıldı. Bütün travma gruplarında, 28 gün sonra sinir örnekleri alınarak biyokimyasal ve histopatolojik olarak incelendi. BuLGuLAr: Çalışmamızda günlük tüketim EGKG, 25mg/kg EGKG, 50mg/kg EGKG gruplarında istatistiksel olarak anlamlı düzeyde lipid peroksidasyonunun azaldığı ve özellikle travma+günlük tüketim EGKG, travma+25 mg/kg EGKG grularında histolojik olarak da dejenerasyon ve ödemin olumlu yönde azaldığı saptanmıştır. soNuÇ: Bu çalışma kateşin ve türevlerinin periferik sinir hasarı gibi nöronal hasarlanmalarda koruyucu etkisinin olduğu gösterilmiştir.

biochemical and histopathological Effects of Catechin on Experimental Peripheral Nerve Injuries

Öz:
AIM: Catechin is a type of polyphenol, along with epicatechin, epigallocatechin, and epigallocatechin-gallate (EGCG). This study aims to investigate the effect of EGCG, a major metabolite of catechin, which is the principle bioactive compound in green tea, on rats with peripheral nerve injury. MATErIAL and METHods: A total of 74 rats were divided into six groups, namely the control, the trauma, the normal saline, a 25mg/kg EGCG, a 50mg/kg EGCG and a daily consumption group (10mg/kg EGCG was given intraperitoneally for 14 days before the trauma). Except the first group, the other groups underwent a 1-minute sciatic nerve compression by clip with 50gr/cm2 pressure. Nerve samples were obtained at 28 day after trauma for the biochemical and histopathological analysis. rEsuLTs: Our study showed that the Daily consumption, 25mg/kg EGCG and 50mg/kg EGCG groups demonstrated statistically significant decreased lipid peroxidation levels and particularly daily consumption, and the 25mg/kg EGCG group showed a favourable reduction of degeneration and edema histologically.CoNCLusIoN: This study shows that Catechin and its derivatives have a protective effect on peripheral nerve injury.
