title: [Activity distribution of SDH in liver of mice. A histophotometrical study (author's transl)].
abstract: The paper presents histophotometrical measurements of the histochemical SDH reaction with INT as redoxindicator in comparison with biochemical techniques of the determination of SDH activity (with K3[Fe(CN)6] and INT as indicators) and a histochemical method of elution (with INT as indicator). The measurements were performed on liver of mice. For each method absolute values of activity (10(-9) mol substrat/min-mg liver) are calculated as relative values of activity [%]. The standard deviation of the biochemical methods is approximate +/- 4%, of the histochemical methods +/- 8%. The smallest value of detection is 2.5-10(-14) mol formazan of histophotometrical measurement. The correspondence between the measurements of the relative values of activity by the described methods was secured by statistical tests. A statistically significant proportion of activities between periportal zone and central zone like 100:82 was determinated by histophotometrical measurement.
