Primary outcomes

  1. Study the effect of anticholinergic drugs on insulin sensitivity by assessment of glucose infusion rate during hyperinsulinemic euglycemic clamp.

    Time frame: After Insulin bolus, following will be measured; p-glucose (every 5 minutes), blood samples (every 30 minutes), pulse (every 5 minutes the first hour then every 10 minutes), blood pressure will be measured (the same as pulse).

Secondary outcomes

  1. Study the effect of cholinergic stimulation on insulin sensitivity by assessment ofglucose infusion rate during hyperinsulinemic euglycemic clamp.

    Time frame: measured; p-glucose (every 5 minutes), blood samples (every 30 minutes), pulse (every 5 minutes the first hour then every 10 minutes), blood pressure will be measured (the same as pulse).

  2. Study the possible difference in effect of cholinergic (physostigmine) andanticholinergic (atropine) drugs on insulin sensitivity in a lean and abdominal obese subgroup of subjects.

    Time frame: measured; p-glucose (every 5 minutes), blood samples (every 30 minutes), pulse (every 5 minutes the first hour then every 10 minutes), blood pressure will be measured (the same as pulse).
