Effects of chronic vibration stress on liver, kidney and testes of the soft-shelled turtle Pelodiscus sinensis

Abstract

The effects of chronic vibration stress 61.6±16.6 dB V for 30 min at 2h intervals, 08.00-18. 00h on the histology and physiology of liver, kidney and testes of the soft-shelled turtle Pelodiscus sinensis was examined. P. sinensis exhibited typical physiological responses (increased Cortisol and glucose levels) to vibration stress. In the SG, hepatocytes, kidney and testes showed abnormal tissue morphology compared to the NSG. In the SG, gonadosomatic and hepatosomatic indices (GSI and HSI) showed significant differences relative to before the start of the experiment and to the NSG. These results suggest that chronic vibration caused substantial stress in the animals and P. sinensis could not adapt to chronic stimuli provoked by vibration stress. © GSP, India.
