Body composition of anoxia tolerant and sensitive flies.

Male w1118 flies were fed for 2 days either on a 1S1Y diet or a 10S10Y diet to produce anoxia tolerant or anoxia sensitive states. Flies were then killed (columns 2 and 3) or exposed to a 1 h anoxia (columns 4 and 5) and killed. Total levels of ATP, lactate, phosphate, glycogen, triglycerides and proteins were determined as described in Materials and Methods. Means±sem and the number of independent experiments performed are indicated. AU: arbitrary units, ND: Not determined. §: p>0.05 as compared to starvation stressed flies after 1 h of anoxia. §§: p>0.05 as compared to starvation stressed flies. Other differences were statistically significant (p<0.01).
