饥饿胁迫对卵形鲳鲹幼鱼消化器官组织学的影响
Effects of Starvation Stress on the Histological Structure of the Digestive Organs for Juveniles of Trachinotus ovatus
摘要
Abstract
By using morphorlogy and paraffin section technique, effects of starvation stress on the histological structure of the digestive organs including esophagus, stomach, pyloric caecum, intestine and hepatopancreas and their characteristics of changes were investigated in 375 juveniles of Trachinotus ovatus starved for 0, 3 , 6, 9 and 12 d respectively for the purpose of understanding the changes in morphorlogy and histology and capacity of tolerence under starvation. The histology results show that effects of the short time starvation within 3 d on the digestive system were of no significance, with starvation time injury began to occur in digestive organs. The damage to digestive organs was lesser from the 6 to 9th days after starvation, and on 12th days after starvation, severe damage were found. Lumen of digestive tract became narrow and thinning, the epithelial cell boundaries were blurred , epithelial failed off and fractured, and secretory cells bacame smaller in size. Damage of histological structure in esophagus by starvation were minor compared with other organs. The effects of starvation were similar about the histological structure of the stomach, pyloric caeca and intestinal tract. Severer damage were found in hepatopancreas than other organs. In conclusion changes to varying degrees took place in digestive organs of juveniles of T. Ovatu by starvation, and effect of starvation on differenct organs varied as time.关键词
