Study Start Date:	December 1978

Detailed Description:

PROTOCOL OUTLINE: Patients fast for 6 hours. Glucagon IM is administered after the 6 hour fast. Glucose level is measured at 0, 15, 30, 45, 60, and 90 minutes.

In children of sufficient size, alanine and lactic acid should also be measured at each or most of these time points.

Fasting continues for at least 18 hours. Glucagon IM is administered again at end of fast. Glucose level is measured at time 0, 15, 30, 45, 60, and 90 minutes.

Eligibility

Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

PROTOCOL ENTRY CRITERIA:

Diagnostically documented elevation in lactate, pyruvate, and/or alanine levels in lactic acidemia patients
