The presence of high-molecular intestinal alkaline phosphatase (HIALP) different from bone ALP detected in the alpha(2)beta region was recently clarified. In this study we used a novel method in which HIALP was detected after conversion to ALP(5) by protease to investigate the clinical significance of the appearance of HIALP in patients with chronic liver disease. The subjects were 241 patients with chronic liver disease. When a decrease in ALP(3) in the alpha(2)beta region and an increase in ALP(5) in the beta region were noted, the patient was judged HIALP-positive. In the patients with chronic liver disease, the total ALP activity (T-ALP) increased with progression of the pathology in the order of chronic hepatitis (CH), liver cirrhosis (LC), and hepatocellular carcinoma (HCC). HIALP appeared in 22.4% and 49.3% of patients with CH and LC, respectively, but the positivity rate decreased to 30.4% in HCC. As autoimmune liver diseases, primary biliary cirrhosis (PBC) and autoimmune hepatitis (AIH) were investigated. T-ALP was lower in PBC+AIH than in LC and HCC, but the HIALP-positive rate was high (44.4%). The HIALP-positive rate was dependent on ABO blood groups, and was high in blood groups B and O. In conclusion, the HIALP-positive rate was particularly high in patients with chronic liver disease, and was related to the pathological progression, which suggests that the method is clinically useful. 相似文献

The isoenzyme of alkaline phosphatase from normal liver, the corticosteroid induced isoenzyme of alkaline phosphatase from serum and liver and a hepatocellular variant isoenzyme of alkaline phosphatase induced by lymphosarcoma have been partially purified and their the present modification incorporates Polybrene into buffer to eliminate this heparin interference. The proposed method shown excellent agreement with a reference procedure based on clottable protein, and excellent day-to-day precision (C.V.3.5%). The present method is easily adaptable to semi-automated measurements. 相似文献

The alkaline phosphatase in homogenates of human liver was separated into two components by the addition of Triton X-100 to an agarose gel electrophoretic system. One of these components migrated at a rate identical to that of the original one and similar to alpha2-macroglobulin. The other component migrated more slowly, at a rate that resembled that of beta1-transferrin. Human serum samples regularly contained an identical fast-migrating fraction, whereas an identical slowly migrating fraction only appeared in serum obtained from patients with various diseases, especially from patients with malignant tumours, even though the liver did not contain tumour metastases. Slow isoenzyme was found in a few sera that had alkaline phosphatase activity within the normal range. Histochemical examinations of liver tissue from patients whose serum contained the slowly migrating isoenzyme showed a pronounced reaction of alkaline phosphatase in the bile canaliculi, and this isoenzyme seems to arise from the canaliculi. The fast-migrating isoenzyme might arise from the endothelial cells of the liver, to which the activity is usually confined in histochemical stainings. 相似文献

A more sensitive modification of the King—Armstrong method of determination of serum alkaline phosphatase has been utilised to determine the total serum alkaline phosphatase and its thermostable fraction in normal subjects and in some diseased subjects. The thermostable fraction is increased above normal in tuberculoid leprosy, but with no significant change in thalassaemia and lepromatous leprosy. Total serum alkaline phosphatase behaved oppositely with respect to these conditions. 相似文献

Coupling two Technicon AAII samplers synchronised at 50 per hour with a 2 : 1 sample to wash ratio, sera are denatured and collected automatically. The incubation is done in continuous flow by passage through a U device made of large metallic needles soaked in a water bath at 60 ± 0.1°C. This allows a very quick temperature equilibration and a very reproducible incubation time of 35 sec. Initial and residual activities of alkaline phosphatase (ALP: EC 3.1.3.1) are measured on a Rotochem II (Aminco) with the procedure recommended by the Société Franlaise de Biologie Clinique (SFBC). For a mixture of bone and liver ALP, the initial rate constant of heat denaturation Kapp = (A × Kb) + (B × K1), where A and B are the fractions of each isoenzyme in the mixture, and Kb and K1 the rate constants for bone (b) and liver (1) experimentally determined as 1.8 min?1 and 0.45 min?1 respectively. An equation was derived which converts the percent residual activity to a percentage of bone and liver isoenzyme: % bone ALP = 183 ? 2.38 ×% residual activity. This automated method was applied to 2700 people of both sexes from 4 to 100 years old. 相似文献
