Abstract

The Effects of the High Pressure on the Body Temperature and the Oxidation • Reduction potential of Blood.
The effects of the high pressure air atmosphere on the body temperature (blood, liver and muscle) as well as the oxidation-reduction potential of blood have been investigated. The findings are summerized as follow :
1 — The body temperature recorded from blood, liver and skeletal muscle diminishes under hyperbaric conditions.
2 — Temperature diminition becomes more prominent as much as the surrounding atmospherial pressure is increosed as well as the duration of the experiment is prolonged.
3 — The most prominent fall in temperature is observed on the skeletal muscle, and a modarate diminition is seen on the blood and liver respectively.
4 — The oxidation-reduction potential of blood decreased in relation with the icrease in ambien pressure.
The above mentioned findings and especially the decrease in the oxidation-reduction potential of blood parallel to the decrease in the body temperature suggests that the lovering of the body temperature under the hyperbaric conditions may be related to the fermentatif blokage in the cells responsible from the heat formation.
The effects of CO. and Hydrogen ion concentration affected by the hyperbaric 02 atmospher is also discussed.

Abstract

Kedilerde, yüksek basıncın vücut ısısı ( kan, karaciğer, kas) ve kanın oksido-redüksiyon potansiyeli üzerine tesiri araştırılmıştır. 2—7 atmosfer hava basıncı altında yapılan deneylerde ısı, kan (vena cava inferior), karaciğer ve kastan yazdırılmış, kanın oksido—redüksiyon potansiyeli yine vena cava inferiordan ölçülmüştür.
2—7 atmosfer basınç altında yapılan deneylerden elde edilen bulgular kontrol deneyleri ile mukayese edilerek aşağıdaki sonuçlara varılmıştır.
1 Yüksek hava basıncına maruz bırakılan tecrübe hayvanlarında vücut ısısı düşmektedir.
2 — Ortam basıncı yükseldikçe ve basınca maruz kalma süresi uzadıkça ısı düşmesi artmaktadır.
3 — Yüksek basınç altında en fazla ısı düşmesi kasta, ikinci derecede karaciğerde, en az ısı düşmesi kanda olmaktadır.
4 — Ortam basıncının artması ile kan redoks—potansiyelinde bir azalma meydana gelmektedir.
Yüksek atmosfer basıncı altında husule gelen ısı düşmesine redoks—potansiyel azalmasının da refakat etmesi, ısı teşekkül mekanizmasındaki fermentatif oksidasyon olaylarında bir inhibisyo.n meydana gelmiş olduğunu telkin etmektedir. Bunun da, ortam basıncının yükselmesi ile organizmada artan oksijenin C02 transpor-
tunu bozup, pH düsmesine sebeb olmak ve enzimler üzerine tesir ederek aktivitelerini azaltmak sureti ile hiyolojik oksidasyonu bosmasmdan ileri gelebileceži münakasa edilmiştir.
