Abstract A radioimmunoassay for parathyroid hormone is described that circumvents some previous difficulties. Parathyroid hormone binds strongly to other serum components. Consequently, a "control" curve is set up for each specimen, the specimen consisting of serum, diluent, and radiolabel, but no antibody. Final calculations are then based on the difference between the control curve and the curve obtained by incubating serum, diluent, radiolabel, and antibody. The lack of parallelism between various sample curves makes it almost mandatory that curves derived from at least 12 dilutions of serum be included for each specimen.

Right ventricular (RV) function was investigated in nine fetal lambs (125-130 days gestation) that were instrumented with pulmonary artery electromagnetic flow sensors and vascular catheters. Control arterial CO2 and O2 tension, pH, and hematocrit values were 46.1 +/- 1.6 (SD) Torr, 20.6 +/- 1.8 Torr, 7.39 +/- 0.02, and 31 +/- 5.3%, respectively. Control values for right ventricular output (247 +/- 75 ml X min-1 X kg-1), stroke volume (SV, 1.5 +/- 0.4 ml X kg-1), right atrial pressure (3.7 +/- 1.2 mmHg), heart rate (166 +/- 18 beats X min-1), and arterial pressure (AP, 43 +/- 4 mmHg) were unchanged by administration of atropine and propranolol. Withdrawal and infusion of fetal blood with or without concomitant infusion of nitroprusside or phenylephrine produced RV function curves at low, normal, and high arterial pressures. All function curves had a steep ascending limb and a plateau. The breakpoint joining the limbs of the control curve was right atrial pressure 3.4 +/- 1.2 mmHg and SV 1.5 +/- 0.4 ml X kg-1. Increased AP shifted the breakpoint downward. Linear regression of SV on AP from 15 to 95 mmHg at right atrial pressure greater than breakpoint was SV = -0.016 ml X kg-1 mmHg-1 X AP + 2.25 ml X kg-1.

MC9S12DG128 microcontroller as the core, designed a simple automatic resistance tester. Measuring range is 100Ω, 1KΩ, 10KΩ, 10MΩ four gears, accuracy ± (1% reading +2 word); From big to small scanning way, performing the basic measurement and automatic switching function, At the same time, automatically display a decimal point and unit. Key input module to complete the setup by screening resistance and errors, the microcontroller output PWM control servo rotation speed, in order to achieve different potentiometer speed control; Curve display module real-time displays the measured data, and the rotation angle of the potentiometer is displayed in graph form. Using the powerful function of LCD, display Chinese characters, to increase readability, improve the usability of tester. The system is cost-effective, high reliability, has a good application prospect.
