[Effect of temperature on the heart function of the five-strip eyebrow squirrel].

This is an in vitro study designed to assess the effect of temperature variation on the heart function of the five-strip eyebrow squirrel--amammal of the hibernating kind. A heart model of exsomatizing action and for determining the physiological parameters with four physiological recorders was used to measure the LVSP, LVEDP and (+/- dP/dtmax), respectively. It was found that the curves of the squirrel's heart mechanics property in relation to temperature variation are similar to the curves of the non-hibernating animals'. But, the squirrels' heart contraction function changes with in a much wider range, suggesting that their hearts are more tolerant of temperature variation.

[Study on animal models for hyperlipidemia].

To establish a better animal model for hyperlipidemia, three animal models with SD rats, Wistar rats and golden hamsters were explored. The semi-purified diet for rats was composed of 1% cholesterol, 10% lard, 10% yolk powder and 79% normal diet. The semi-purified diet for hamster was composed of 0.2% cholesterol, 15% lard and 85% normal diet. Serum TC, TG, HDL-C, liver cholesterol and triglyceride were assayed. Serum TG of SD rat, Wistar rat and hamster was 194.4%, 86.2% and 84.3% respectively higher than that of control after 5 weeks of experiment. Serum TC of the three groups was 76.8%, 48.3% and 134.8% respectively higher than that of control. The results suggested that hamster might be a better animal model for hypercholesterolemia and SD rat might be better for hypertriglyceridemia.
