Abstract A cytochemical study of 54 cases of acute leukemia utilizing the periodic acid-Schiff reaction for glycogen and Oil Red O for neutral fat was performed on air dried bone marrow smears. The majority of leukemic lymphoblasts revealed significant amounts of glycogen and neutral fat. "Blast" cells in granulocytic leukemia were devoid of glycogen and of neutral fat. The recommendation is made that both of these histochemical stains be employed to attempt to resolve the problem of specific cellular identification in acute leukemia.

Abstract The classification of the acute leukemias depends mainly on the morphologic and cytochemical evaluation of the blast forms. One of the main accepted morphologic criteria in the differentiation between acute lymphoblastic leukemia (ALL) and acute myeloblastic leukemia (AML) is the absence of granules in the blast cells of ALL. We evaluated a patient with ALL in whom granules were present in the cytoplasm of 35% of the blast cells, as seen in AML. Cytochemical evaluation was performed, including periodic acid-Schiff reaction, Sudan black B, alpha-naphthyl acetate, alpha-naphthyl butyrate, naphthol AS-D chloroacetate, and acid phosphatase stains. The results of these studies confirmed the morphologic impression and diagnosis of ALL. Ultrastructural evaluation revealed that the granules consisted of many tiny vesicles closely packed together in a proteinaceous matrix, resembling to some extent the inclusions described in lymphocytes in the Chediak-Higashi syndrome, but clearly different. The morphologic, cytochemical, and ultrastructural studies of this unique case are presented in detail. To our knowledge, this is the first time that such granules have been described in blast cells of ALL.

Abstract Stoward1 conjugated acidified solutions of salicyloyl hydrazide with the dialdehydes formed from the periodic acid oxidation of vicinal glycols in guinea pig tissue sections. The method has now been utilized, with minor modification, to demonstrate glycogen in blood and marrow cells, and it has been compared with the periodic acid-Schiff reaction and with a fluorescent acriflavine Schiff-type method. It is felt that the PA-SH method will replace the existing Schiff-type fluorescent methods and that it will prove to be a useful technic to aid in the diagnosis of blood conditions, such as acute leukemia, where PAS positivity is known to occur.

Muscle performance and structure was studied in rat soleus muscle with limited blood supply in combination with chronic muscle stimulation. Blood supply to the lower leg was restricted by ligation of the common iliac artery, electrodes were implanted in the vicinity of the sciatic nerve and ankle flexors were denervated. Three days later, soleus and gastrocnemius muscles were stimulated at 4 Hz four times a day for a period of 20 min with 2 h intervals between stimulations; this procedure was continued for 4 days. Muscle performance, histochemistry and ultrastructure were studied on the eighth day after operation in these muscles and in ischaemic unstimulated muscles with denervated ankle flexors. Both were compared with control animals. Muscles with limited blood supply developed less isometric twitch tension than control muscles (peak twitch tension in ischaemic muscle was 60.3 +/− 4.8 g g-1 muscle, mean +/− S.E.M., compared to 79.7 +/− 6.9 g g-1 in control muscle; tensions after 5 min contraction were 54.5 +/− 5.5 g g-1 in ischaemic muscle compared to 70.6 +/− 6 g g-1 in controls). Stimulated muscles with limited blood supply had higher peak (85 +/− 16.6 g g-1) and final (87 +/− 12 g g-1) tensions, and also fatigued less than muscles with limited blood supply but no stimulation. Histochemical estimation of capillary density (by staining for alkaline phosphatase) and slow (SO) and fast (FOG) fibres (by myosin ATPase staining) revealed similar capillary to fibre ratios (2.5) and a similar proportion of FOG fibres (around 18%) in all muscles. The proportion of glycogen-depleted fibres (estimated from the periodic acid Schiff reaction, PAS) in muscles removed from animals 10 min after a 5 min period of isometric twitches was significantly lower in ischaemic muscles (45.1 +/− 1.9%) than in control (80.5 +/− 1.5%) or chronically stimulated ischaemic muscles (67.3 +/− 4.0%). Electron microscopy showed disorganised myofibrils with Z-line streaming in 7.48 +/− 3.04% of fibres in muscles with limited blood supply. Swollen and degenerated mitochondria, dilated sarcoplasmic reticulum and areas of disrupted sarcolemma were also observed. Stimulated ligated muscles showed a significantly lower proportion of fibres with disorganised filaments (0.65 +/− 0.32%) and other signs of damage were much less frequent. The reduced damage and improved performance of chronically stimulated slow muscle may be the result of improved microcirculation, preventing accumulation of lactate.

Abstract Human kallikrein-related peptidases 3, 4, 11, and KLK2, the activator of KLK3/PSA, belong to the prostatic group of the KLKs, whose major physiological function is semen liquefaction during the fertilization process. Notably, these KLKs are upregulated in prostate cancer and are used as clinical biomarkers or have been proposed as therapeutic targets. However, this potential awaits a detailed characterization of these proteases. In order to study glycosylated prostatic KLKs resembling the natural proteases, we used Leishmania (LEXSY) and HEK293 cells for secretory expression. Both systems allowed the subsequent purification of soluble pro-KLK zymogens with correct propeptides and of the mature forms. Periodic acid-Schiff reaction, enzymatic deglycosylation assays, and mass spectrometry confirmed the glycosylation of these KLKs. Activation of glycosylated pro-KLKs 4 and 11 turned out to be most efficient by glycosylated KLK2 and KLK4, respectively. By comparing the glycosylated prostatic KLKs with their non-glycosylated counterparts from Escherichia coli, it was observed that the N-glycans stabilize the KLK proteases and change their activation profiles and their enzymatic activity to some extent. The functional role of glycosylation in prostate-specific KLKs could pave the way to a deeper understanding of their biology and to medical applications.

The histochemical use of methylation has complex results; particularly in respect of the periodic acid-Schiff reaction, these are analyzed and discussed. Methods are described which allow the separate study of the following effects: (a) the removal of the KOH/periodic acid-Schiff effect; (b) removal of sialic acid from a potential vicinal diol; and (c) the removal of O-sulfate ester from a potential vicinal diol. The use of the Smith degradation technique, in addition to the above, also allows inferences to be drawn in respect of the structure of the mucins (glycoproteins) being investigated.

Systemic mastocytosis was diagnosed in a 4-year-old, female Nubian goat. Clinically, the animal was depressed and had severe macrocytic hypochromic anemia and leukopenia. Postmortem examination revealed neoplastic mast cells invading the heart, lung, liver, spleen, lymph nodes, and bone marrow. Eosinophils were frequently admixed with infiltrating mast cells in all organs. Using routine light microscopy, histochemistry, and transmission electron microscopy, metachromatic and periodic acid—Schiff–positive granules were identified within the cytoplasm of neoplastic mast cells. Erythrophagocytosis was observed in some neoplastic cells, although its contribution to the anemia was not clear. This report represents the first description of mast cell neoplasia in the goat.

Nonspecific Esterases

Proteins extracted from individual pairs of salivary glands or other larval tissues of Sciara coprophila (Diptera) were separated in a vertical microsystem for discontinuous electrophoresis using thin sheets of polyacrylamide gel cast in multiple layers of varying pore size. After electrophoresis at 150 volts for 40 min, gels were stained ( a) for total proteins with Coomassie brilliant blue, ( b) for glycoproteins with the periodic acid-Schiff reaction, ( c) for lipoproteins with Sudan black B or ( d) for nonspecific esterases with fast blue RR as coupler and α-naphthol acetate as substrate. Sequential application of these reactions to individual gel sectors permitted direct comparisons of protein profiles for 15-20 different samples of tissue extracts carried on a single gel sheet in adjacent lanes and thus subjected to identical conditions of electrophoresis. Representative photographs and densitometric scans are presented to show the suitability of thin gel sheets for autoradiography and for both qualitative and quantitative evaluation of tissue-specific differences in patterns of protein banding found for salivary gland cells, the gastric ceca, or the hemolymph of individual Sciara larvae sacrificed at particular stages of fourth instar development. Innovative details of methodology are presented, including the use of a microspectrophotometer to scan electropherograms of insect proteins and several types of human blood serum.
