Physiological Research

ABSTRACT Heat-sensitive Pawn (ts Pawns) of Paramecium aurelia behaved normally when grown at 23° but failed to avoid strong stimuli at 35°. Four of the five ts Pawn lines tested were found to be allelic at a locus known also to carry temperature-independent Pawn mutations. The fifth ts Pawn line complemented all the conditional and unconditional Pawn mutants of the two known loci. This result, together with the patterns of F2 segregation from various crosses, suggested the existence of a third Pawn locus. An additive effect of the unlinked ts Pawn genes was observed. These findings and the significance of ts Pawns as experimental material in behavioral and physiological research are discussed.

SummaryThis, the first in a series of three, describes the medical aspects of the JSE to Brabant Island, Antarctica. The expedit ion was conceived and led by Commander Chris Furse RN, was logistically light and simple, and used tents instead of huts for accommodation. Main achievements included a 140 mile journey in Sm inflatable boats, the first ascents of 55 peaks, the first complete overwintering in tents, and the 100 mile circumnavigation of the island by canoe. Apart from the well-publicised crevasse fall in which Lieutenant Commander Clive Waghorn RN fractured his femur, medical problems were few and minor. The planning, preparations and problems are described in detail, and subsequent articles will deal with physiological research and clothing and equipment.

And Training

The work is devoted to a brief description of the preparation and conduct series of scientific experiments in the underwater laboratory “Chernomor” during the period of 1967–1972. The experiments were carried out at the depths from 8 to 30 meters. The place of the experiments is the Southern Branch of the Institute of Oceanology (Gelendzhik). It was unique experiments in the duration of a person’s stay underwater. The maximum depth for “Chernomor” was identified, the optimal methods of organizing work in underwater inhabited houses and the permissible depths for the use of nitrogen-oxygen breathing mixtures were determined. Specialized medical and physiological research was carried out to develop a methodology for the selection and training of aquanauts for future scientific crews. “Chernomor” was the only underwater house in the world that served on the seabed for five seasons in a row. More than 50 scientists from all over the country worked in it in different crews. The work is a tribute to the memory of all enthusiasts and dreamers: designers and developers, engineers and technicians, divers and scientists, everyone involved in those unforgettable events.
