- 1)The oxygen consumption was studied with albino rate under normal environment after they were given Cytochrome C intravenously (10mg/kg). The consumption was 74.6cc/kg min. with that of control, 75.4cc/kg. min. The difference of the consumptions was not statistically significant. However, under 0.5% CO environment, the oxygen consumption of the Cytochrome C treated rats (62.5cc/kg min) was significantly greater than the control(42.1cc/kg min.) 2) The recovery time of rat acutely poisoned by 1% CO was studied. The recovery time of the Cytochirome C treated group was 37.2 minutes and in control group it was 52.2 minutes. Also significant difference of fatality was noted between the treated group(21.8%) and the untreated group(49.7%). 3) The combined effects of the hyperbaric oxygenation (100% O2 at atmospheric pressures) and the Cytochrome C administration was compared with the effect the simple hyperbaric oxygenation. There was no significant difference of recovery time between the experimental group while the fatality of the experiment group was lower than control group.

- The study in the fild of medical instrument has been out of the interest by any the life scinetist in Korea. Especially the recent developments in the medical electromics are remarkable one. Authors planned this study to ascertain the possibility of setting up the thermistor thermometer with available accessories of demetic products including some specific foreign assembly parts. By proper use of the thermistor as one of the wheatstone bridge, we could detect the resistance variations due to the environmental temperature variance. The intensive care for the bridge circuit and compensation scheme was required. The calibration procedure adopted here makes it possible to read the current as the temperature. The temperature range was determined by the examination and construction of the graph of the resistance-temperature, the reduction of excessive current and self-heating of the thermistor were made. Renovation in response-velocity was under taken too. This electronic thermometer was designed and assembled by the circuitry developed in accordance with the maximum availability of domestic products with some foreign-made parts. The result of our experiment showed very stable function and proved to be the most promising item in the actual application as long as the thermistor is concerned.
