Rewarming from immersion hypothermia: a comparison of three techniques.

Rewarming from immersion hypothermia has been assessed in sheep by the use of three techniques--hot bath, body insulation and airway warming. Though the hot bath was the fastest of the methods of rewarming studied, consideration of temperature gradients and therefore total body heat diminished its advantage in comparison with central body rewarming via the airway (CBRW), which in turn showed considerably advantage over body insulation alone. CBRW did not have any thermal advantage gained on assisting the ventilation as compared with spontaneous breathing. The results illustrate the importance of adequate insulation of the body to prevent further heat loss and this was found to be true whether or not airway warming was being used. The site of heat uptake with CBRW was determined and observations were made on the physical behaviour of temperature gradients.

Viruses in osteosarcomas induced by 226Ra. A study of the induction of bone tumours in mice.

Three groups (15 in each) of 3-month-old mice were injected intraperitoneally with 0-5 muCi 226Ra. They were male and female C3H/H and female CBA/H. The groups were matched by similar controls that were not injected. Osteosarcomas were found in 14/15 of the female C3H/H mice--animals known to carry mammary-tumour viruses in milk--compared with 6/15 in their male counterparts. In CBA/H female mice, which have a very low incidence of both mammary tumours and leukaemia, osteo-sarcomas developed in 7/15 of the animals. The CBA/H mice lived about 5-8 months longer and revealed their osteosarcomas at a correspondingly later time than C3H/H mice. Virus particles were observed in each of the three mammary tumours and in 15 out of the 17 osteosarcomas examined by electron microscopy. No definitive statement can be made from this experiment whether or not osteosarcoma was caused by a virus; but the results suggest that viruses may be a contributory factor in the development of osteosarcoma in these animals.
