A Clinical Study on the Development of a Simplified Fat Absorption Test by Simultaneous Administration of $^{125}I$ -triolein and Chromic Oxide( $^{51}Cr_2O_3$ )
1969
The conventional triolen absorption test has its defect in that the stool collection was cumbersome, time and energy-wasting. In the present study, the triolen absorption test was carried out using double tracer technique with to determine if it can overcome the defect of the conventional method also with satisfactory results. Following were the results: 1. The clinical significance of this double tracer method was essentially the same with that previously done by radioactive. triolen alone. With the fractional fecal samples, the equation, y=0.626x+2.010 was substantiated, hence, this method appears to be clinically valuable if the appropriate correction is applied. With the mixed fecal samples, the equation y=0.642x+1.468 was substantiated (p. 2. The normal ranges of the fecal triolen excretion rate in this double tracer method were , namely, less than 6.9%. 3. The samplings were done from the first to third defecation in cases of clinically normal, and from the first to second defecation in cases of diarrhea or malabsorption. 4. The intestinal malabsorption of triolen was not observed in whom the triolen absorption was supposed to be clinically normal, however. a good number of suspicious malabsorptive cases showed the normal values.
