Metabolic changes in the medical leech Hirudo medicinalis following feeding
Abstract 1. 1. In Hirudo, feeding results in a dramatic rise of the metabolic rate as indicated by O2 consumption, excretion of nh3 and elimination of ions and water, each showing a characteristicExpand

Anaerobic metabolism in aquatic insect larvae: studies onChironomus thummi andCulex pipiens
SummaryThe metabolic effect of hypoxia and anoxia on the larvae ofChironomus thummi andCulex pipiens was investigated. InC. thummi anoxia resulted in a characteristic decrease of ATP and P-arginineExpand

The energy metabolism of the leechHirudo medicinalis in anoxia and muscular work
The medical leech Hirudo medicinalis has only small reserves of glycogen (˜ 40 μmol/g fresh weight), but malate is present in comparatively high concentrations (8 to 10 μmol/gm fresh weight) in theExpand

In vivo -studies on the function of hemoglobin in the larvae of Chironomus thummi (insecta, diptera)
1. 1. The respiratory rate of the larvae of Chironomus thummi was monitored in a closed system. It was virtually constant until the pO2 declined below 10 Torr. 2. 2. When hemoglobin wasExpand
