Abstract (2. Language): 
The purpose of this study was to investigate the effects of heat shock protein 72 (HSP72) on muscle atrophy in diabetic rats. Forty-two male Sprague-Dawley rats (Age = 4 weeks; Xbody mass=147±4g) were randomly assigned to one of 5 experimental groups. Four groups were formed to study muscle atrophy: Control (CONT, n=6), Heat Stress (HS, n=6), Diabetic (D, n=12) and Heats Stress-Diabetic (HS-D, n=13). The fifth group, Heat Stress-1 (HS1, n=5), served to determine the degree of HSP72 induction 24 hours following heat stress. HSP72 was induced by placing the rats in a hot water bath. During the bath rats' rectal temperatu¬re was constant at 42°C for 15 minutes. Twenty-four hours after heat stress, a single dose of (125mg kg-1) of streptozotocin was injected intraperitonealy to the rats in HS-D group and D group to induce diabetes. Five days after streptozotocin injection all animals were anest¬hetized, muscle tissues (SOL, EDL) were removed, weighed and analyzed for HSP72 levels. One dimensional electrophoresis and immunoblotting techniques were used to analyze HSP72. Compared to those of non-diabetic groups, blood glucose levels were significantly higher (P<0.05), and both body masses and absolute muscle masses were significantly lo¬wer in diabetic groups (P<0.05). Relative muscle HSP72 levels were higher in all experimen¬tal groups compared with the corresponding control values. There was no significant diffe¬rence in muscle atrophy between HS-D and D groups (P>0.05). Induction of stress proteins was not effective in reducing diabetic muscle atrophy.

Bu çalışmanın amacı, sıcak şoku proteini 72'nin (HSP72) diyabetik sıçanlarda kas atrofi-si üzerine etkisini araştırmaktır. Kırkiki erkek Sprague-Dawley sıçan (Yaş = 4 hafta; Xvücut küt-lesi=147±4g) rastgele yöntemle 5 deney grubuna ayrılmıştır. Gruplardan dördü kas atrofisinin araştırılması için oluşturulan; Kontrol (KONT, n=6), Sıcak Stresi (SS, n=6), Diyabetik (D, n=12) ve Sıcak Stresi-Diyabetik (SS-D, n=13) grupları olup, beşinci grup olan Sıcak Stresi-1 (SS1, n=5) sıcak stresi uygulamasından 24 saat sonra HSP72 indüklenme düzeyinin belirlenmesi amacıyla oluşturulmuştur. HSP72, sıcak su banyosu yöntemi kullanılarak indüklenmiştir. Sı¬cak su banyosu sırasında, hayvanların rektal vücut sıcaklığı 15dk süresince 42°Cde sabit tu¬tulmuştur. Sıcak stresi uygulamasından 24 saat sonra SS-D ve D gruplarındaki hayvanlara tek doz streptozotosin (125mg kg-1) intraperitoneal olarak enjekte edilerek diyabet oluşturul¬muştur. Streptozotosin enjeksiyonundan 5 gün sonra tüm hayvanlara anestezi uygulanarak, soleus (SOL) ve ekstansör digitorum longus kasları izole edilmiş, tartılmış ve HSP72 analizi yapılıncaya kadar -80°C derin dondurucuda saklanmıştır. HSP72 analizinde tek boyutlu po-liakrilamid jel elektroforezi ve immünoblot teknikleri kullanılmıştır. Diyabetik olmayan gruplar¬la karşılaştırıldığında diyabetik grupların kan glikoz düzeyi daha yüksek (P<0.05), vücut küt¬lesi ve mutlak kas kütlesi daha düşük (P<0.05) bulunmuştur. Kas dokularındaki relatif HSP72 düzeyleri tüm deney gruplarında kontrol grubu değerlerinden yüksek bulunmuştur. SS-D ve D grupları arasında kas atrofisi yönünden anlamlı fark bulunmamıştır (P>0.05). Sıcak stresi proteini indüklenmesi diyabetik sıçanlarda kas atrofisinin azaltılmasında etkili bulunmamıştır.
