Q: Abstract: Rat liver microsomal insulin-like growth factor-II (IGF-II) receptor has been purified to homogeneity using a single step affinity chromatographic procedure on agarose-IGF-II with elution at pH 4. Determined by either IGF-II binding or a direct RIA for receptor, purification of 2000-fold was obtained. The mean recovery was 28% for five such preparations. Sodium dodecyl sulfate-electrophoresis and autoradiography of purified receptor, radioiodinated receptor, and affinity-labeled receptor all indicated a molecular mass of approximately 250K. Scatchard analysis of IGF-II binding to purified receptor, solubilized microsomal membranes, or plasma membranes showed a single class of binding site with an affinity constant of 6 X 10(10) liter/mol in all cases. Potent antibodies to the purified receptor were raised in rabbits, capable of inhibiting 50% of IGF-II binding at dilutions of 1:170,000 and also of fully precipitating IGF-II-prelabeled receptor at 1:50,000. Both types of antibodies reacted with IGF-II receptors in rat adipose tissue, brain, heart, kidney, lung, and spleen. However, little cross-reactivity was seen with other species. Comparison of the ability of receptor antibodies to inhibit IGF-II binding to microsomal and plasma membranes indicated a specific immunological difference between the IGF-II receptors in the two membrane preparations.

Q: Abstract: A prospective clinical trial was conducted to estimate the rise in serum glucose level after an intravenous bolus of 50 ml of 50% dextrose solution (D-50) in the emergency department setting. Fifty one subjects with altered levels of consciousness were studied. Of these, 23 patients were known diabetics, and 28 were not diabetic. The change in glucose level for the total study group ranged from a low of 37 mg/dl to a high of 370 mg/dl, with a mean of 166 +/- 77 mg/dl. The mean for the diabetic and non-diabetic groups were 177 +/- 80 mg/dl and 154 +/- 75 mg/dl. These results suggest that serum glucose levels cannot be quantitatively predicted after a single intravenous bolus of D-50.

Q: Abstract: The combined effects on performance of two anxiolytics with different mechanisms of action were evaluated double-blind and crossover in 12 healthy students. Objective (tracking, divided attention, Maddox wing, etc.) and subjective (visual analogue scales and questionnaires) tests were done before and twice after single oral doses. Diazepam (0.15 and 0.30 mg/kg) impaired performance dose relatedly and rendered the subjects drowsy, calm, mentally slow, and clumsy. Buspirone (15 mg) proved inactive in objective tests but matched diazepam (0.30 mg/kg) subjectively. In combinations, buspirone added to the effects of diazepam in Maddox wing and letter cancellation but tended to counteract diazepam effects on divided attention and learning acquisition. Subjectively buspirone prolonged diazepam-induced sedation. Increased calmness caused by diazepam was not affected by concomitant buspirone. It is suggested that combining small doses of buspirone to diazepam does not cause any additional decrement in psychomotor performance. Possible advantages of the diazepam-buspirone combination in therapeutic use are discussed.
