August Krogh *
Schack August Steenberg Krogh was born in Grenaa, Jutland. His ancestors had emigrated from Holstein and Schleswig, where his father's family had settled as small farmers three hundred years earlier. Krogh's father was a brewer, though he had been trained as a shipbuilder. Ships and the sea were some of Krogh's unceasing interests. Krogh, who was the oldest of six brothers and sisters, had alre...
متن کاملThe August Krogh principle applies to plants.
The Krogh principle refers to the use of a large number of animals to study the large number of physiological problems, rather than limiting study to a particular organism for all problems. There may be organisms that are more suited to study of a particular problem than others. This same principle applies to plants. The authors are concerned with the recent trend in plant biology of using A...
متن کاملFreshwater fish gill ion transport: August Krogh to morpholinos and microprobes.
August Krogh proposed that freshwater fishes (and other freshwater animals) maintain body NaCl homoeostasis by extracting these ions from the environment via separate Na(+) /NH(4)(+) and Cl(-) /HCO(3)(-) exchangers in the gill epithelium. Subsequent data from other laboratories suggested that Na(+) uptake was more probably coupled to H(+) secretion via a vesicular proton pump (V-ATPase) electri...
متن کاملAugust Krogh and Claude Bernard on Basic Principles in Experimental Physiology
problems there is an animal on which it can be most conveniently studied”—has attained great popularity in the biological literature since it was formulated by Hans Krebs in 1975. Sometimes the reference to Krogh (1929) and his use of the “principle” is, however, misleading or incorrect. Thus, Feder and Watt (1992) cite Krogh for having articulated the principle that “for every biological quest...
متن کاملTeleost fish osmoregulation: what have we learned since August Krogh, Homer Smith, and Ancel Keys.
In the 1930s, August Krogh, Homer Smith, and Ancel Keys knew that teleost fishes were hyperosmotic to fresh water and hyposmotic to seawater, and, therefore, they were potentially salt depleted and dehydrated, respectively. Their seminal studies demonstrated that freshwater teleosts extract NaCl from the environment, while marine teleosts ingest seawater, absorb intestinal water by absorbing Na...
