Early changes and rules of cardiac function and hemodynamics in rabbits with experimental myocardial contusion.
To study changes and rules of the left ventricular functions in rabbits with myocardial contusion through parallel functional analysis by using echocardiography combined with cardiac catheter intervention. ⋯ Cardiac functions of the left and right ventricles are markedly injured after myocardial contusion with disorders of the left ventricle diastolic function and of the right ventricle systolic function as the dominant injury. While the systolic function of the left ventricle can recover. Echocardiography shows clinical importance in detection of early injuries of cardiac functions.

Comparative StudyCompound injection of radix Hedysari to promote peripheral nerve regeneration in rats.
To study the effect of compound injection of Radix Hedysari on peripheral nerve regeneration in rats. ⋯ CIRH can promote regeneration of peripheral nerves and absorption of degenerated and necrotic injured nerves. It has the same effect as NGF.

Effect of mild hypothermia on partial pressure of oxygen in brain tissue and brain temperature in patients with severe head injury.
To study the changes of partial pressure of oxygen in brain tissue (P(bt)O(2)) and brain temperature (BT) in patient s in acute phase of severe head injury, and to study the effect of mild hypothermia on P(bt)O(2) and BT. ⋯ This study demonstrates that P(pt)O(2) and BT monitoring is a safe, reliable and sensitive diagnostic method to follow cerebral oxygenation. It might become an important tool in our treatment regime for patients in the acute phase of severe head injury requiring hypothermia and hyperventilation.
