Lactate dehydrogenase C, an isoenzyme composed of C polypeptide subunits and found only in mature testes and spermatozoa, differs kinetically, chemically and immunologically from the five common isoenzymes of lactate dehydrogenase, each of which is a tetramer of A and/or B subunits. In the rat lactate dehydrogenase C exists in two molecular forms, isoenzymes C4 and A1C3. In addition to these tw...

We have studied five patients who have exhibited an unusual alkaline phosphatase isoenzyme (ALP EC 3.1.3.1) migrating in an ultrafast position electrophoretically on cellulose acetate. This ALP isoenzyme has been identified in patients with benign and malignant liver diseases. In addition, a number of these patients exhibited a regular ALP liver isoenzyme and a fast (preliver) ALP isoenzyme in ...

Evidence of acute pancreatitis was sought in 35 patients with fulminant hepatic failure. Total amylase was raised in 22 patients and isoenzyme separation showed a distinct P3 isoenzyme (indicative of pancreatitis) in 14. In four patients with marked hyperamylasaemia (greater than 1000 U/l) the predominant isoenzyme was the salivary fraction. Pancreatic lipase was abnormally raised (greater than...

Myosin isoenzyme profiles of rat and chicken embryonic cardiac myocytes were studied during differentiation and growth in vitro by native-gel electrophoresis and assay of Ca2+-activated ATPase. The electrophoretic pattern of myosin extracted from 18-day-embryonic-rat myocytes after 7 days in culture exhibits three isoenzyme bands, V1, V2 and V3, of which the slow-migrating V3 is predominant. Th...

Diabetes mellitus is a group of metabolic disorders that share with symptoms hyperglycemia led to elevated free radical activity. Hyperglycemia linked higher level (ADA), which one the factors cause oxidative stress by creating reactive oxygen species (ROS), leads insulin resistance. This study aimed determine relationship between serum total adenosine deaminase(TADA) and its isoenzyme (ADA1and...

HeLa TCRC-1, is a monophenotypic cell line for the production of the carcinoplacental Regan isoenzyme of alkaline phosphatase. It has been previously reported that, when this cell line is grown in immunosuppressed rats, there is an alteration of phenotypic expression in that an isoenzyme that is referred to as oncoamnion (FL) becomes the dominant enzyme form. This report describes the isoenzyme...

The separation of N-acetyl-beta-D-hexosaminidase isoenzymes from human tissues is used in the diagnosis and differential diagnosis of GM(2) gangliosidosis, since in type 1 the A isoenzyme is deficient and in type 2 both the A and B isoenzymes are deficient. Peripheral blood leucocytes are commonly used for these investigations, and the present study demonstrates that, in addition to these two i...

BY CELLULOSE ACETATE OR ACRYLAMIDE GEL ELECTROPHORESIS IT IS POSSIBLE TO SEPARATE THESE ALKALINE PHOSPHATASE ISOENZYMES FROM SERUM: [anode] fast liver, slow liver, placenta/Regan, bone, intestine, bile [cathode]. Heat or chemical inhibition can confirm the differentiation. Normal adult serum always contains slow-liver isoenzyme, and sometimes bone isoenzyme: the latter is always present in seru...

the effects of different storage temperatures and times on germination rate, malondialdehyde (mda), superoxide dismutase (sod), peroxidase (pod) and catalase (cat) activities in jatropha curcas l. seed were investigated. the results showed that germination rates of seeds stored at room temperature and 4°c for 1 month was significantly higher than those stored for 3 months at -20 and -80°c. mda ...

background: cutaneous leishmaniasis (cl) with diverse clinical manifestations is prevalent and remains a major public health problem in iran and its incidence has been doubled over the last decade. the present study is about the potential role of rodents in the epidemiology of cl in kharameh district in shiraz, southern iran. methods: from april 2004 to april 2005, a total of sixteen rodents we...
