Periodic acid-Schiff reaction and prognosis in lymphoblastic leukaemia.
Diagnostic bone marrow smears from 132 patients with acute lymphoblastic leukaemia, (ALL) were stained simultaneously by the periodic acid-Schiff (PAS) reaction, and the blast cell positivity was assessed quantitatively. The patients fell naturally into two unequal groups: those with more than 20% PAS-positive blast cells (44 patients) and those with less (88 patients). There was no relation be...
متن کاملSpectrophotometry of the Periodic Acid-schiff Reaction with Pituitary Hormones in Vitro and in Histological Sections
The spectral light absorption of the in vitro periodic acid-Schiff reactions of 4 purified pituitary hormones is described. The absorption spectra present a maximum between 560 and 565 mmicro. The color developed conforms with Beer's law for the ranges of concentration examined. The different hormones exhibit different chromogenicity per unit of biological activity: the color produced by 1 unit...
متن کاملMystery Case: Lafora periodic acid-Schiff inclusion bodies.
A 16-year-old boy presented with a 5-year history of progressive cognitive decline and behavioral change followed by generalized tonic-clonic and myoclonic seizures refractory to many anticonvulsants (valproic acid, phenobarbital, clonazepam, and topiramate) and cerebellar ataxia a year later. The son of consanguineous parents, he had a family history of 2 cousins who both had epilepsy and died...
متن کاملThe occurrence of the periodic acid-Schiff reaction in various normal cells of blood and connective tissue.
By GEORGE B . WISLOCKI, M.D., JACK J. RHEINGOLD, M.D., AND EDWARD \V. DEMPSEY, PH.D. T HE PERIODIC acid-Schiff method stains glycogen, mucus, reticulum and basement membranes, some kinds ofelastic tissue, fibrin, and various substances ofquite unknown composition (McManus’; Lillie et al.’; Wislocki and Dempsey3). Glycogen may be differentiated from these other substances by the fact that it is ...
