Ventricular weights in guinea pigs acclimated to cold plus hypoxia.

Weanling male guinea pigs (Cavia porcellus), 2-3 weeks of age, with initial body weights of 207-271 g were exposed for 2-16 weeks to constant cold (6 degrees C) and hypoxia (PO2 = 85 Torr) equivalent to 4800 m above sea level. Their growth rates and body weights did not differ from those of control animals of the same age maintained under normoxic… CONTINUE READING
