The effect of depersolone, of the oxygenation of the perfusing solution and of phenoxybenzamine pretreatment has been studied in the isolated rat liver intermittently perfused with a solution containing low molecular weight dextran at 4 degrees C. The use in liver preservation of Collins' C3-solution and of a special albumin-containing solution was tested. The behaviour of acid and alkaline phosphatase, esterase, lactate dehydrogenase and adenosine triphosphatase in the preserved liver was followed by means of histochemical methods allowing semi-quantitative evaluation. Pretreatment with phenoxybenzamine and perfusion by an albumin-containing solution reduced the lesion of the liver, while prednisolone and oxygenation of the perfusion solution improved preserving effect only moderately.

The histochemistry of the neural cells was studied in the submandibular ganglia of 5 Callithrix jacchus (3 males and 2 females) and 4 Callithrix penicillata (2 males and 2 females). These cells contain neutral mucopolysaccharides, nucleoproteins and lipidic materia, but are apparently devoid of glycogen. It is impossible to demonstrate in them any reactivity for UDPG-GT, phosphorylases, ATPase at pH 6.3, leucine aminopeptidase and alanyl aminopeptidas. The reaction for the other searched enzymes was as follows: weak (F-1,6-P Ald and cytochrome oxidase), weak to moderate (ADH, 6-P-GDH, ICDH, SDH, MDH, alpha-GPDH and beta-OHBDH), moderate (G-6-PDH, F-1,6-PA, LDH and GDH), moderate to strong (ATPase at pH 7.4, nonspecific esterase and acid phosphatase) and strong (G-6-PA, NADH2,-TR, NADPH2-TR, ATPase at pH 8.5 and 9.4 and alkaline phosphatase).

A total of 130 smears from 77 patients with various diseises (42 patients with tumors, 35 patients with specific and non-specific lung diseases) were investigated with enzyme cytochemical methods with regard to the practical application of enzyme cytochemistry in pleural effusions. It is possible to demonstrate all investigated enzymes on normal air-dried or aceton-fixed smears without any technical problems. Between tumor and mesothelial cells a different reaction on some enzymes (alkaline phosphatase, non-specific esterase, aminopeptidase, beta-glucuronidase) could be found valuable for diagnostic purpose. For application in praxi alkaline phosphatase seems to be most important. 70% of all pleural effusions of tumorous origin contain alkaline phosphatase positive tumor cells.

The study deals with the distribution of acid and alkaline phosphatases, ATPase, 5-nucleotidase, nonspecific esterase, specific cholinesterase, and beta-galactosidase in the diencephalon of the frog. The highlights of the present study are the following: i) Acid phosphatase is present in all the neurons, whereas the tracts and commissures are completely negative. ii) Most of the tracts and commissures are positive for 5-nucleotidase. This confirms the author's previous findings that the tracts and commissures of all the areas of frog brain are intensely positive for 5-nucleotidase. iii) beta-galactosidase activity in the nuclei of the diencephalon is either mild or completely absent, whereas the commissures and tracts show positive activity. iv) Habenulothalamic connections are intensely positive for specific cholinesterase and non-specific esterase, moderately positive for beta-galactosidase and completely negative for other enzymes. v) The epiphysis (pineal organ) shows intense reaction for adenosine triphosphatase, acid phosphatase, and 5-nucleotidase and moderate reaction for alkaline phosphatase and non-specific esterase. In contrast to the above enzymes, the specific cholinesterase and beta-galactosidase are completely missing. vi) Lateral forebrain bundles are completely negative for all the enzymes except alkaline phosphatase and beta-galactosidase. The distribution of these enzymes has been correlated with the functional aspects of various nuclei, tracts, and commissures of the diencephalon of the frog.

The epithelial cells in the taste buds of C. jacchus and C. penicillata show a moderate amount of ribonucleic acid an a concentration of a PAS-positive diastase-resistant material at their apical part. These cells are devoid of UDPG-GT, phosphorylases, G-6-PA, alanyl aminopeptidase, leucine aminopeptidase, cholinesterase and MAO; they present a weak reaction of F-1, 6-P Ald, LDH, SDH, MDH, cytochrome oxidase, beta-OHBDH, nonspecific esterase and acid phosphatase and a stronger reaction to ADH, NADPH2-TR, ATPases, alpha-GPDH, alkaline phosphatase, 5-nucleotidase and GDH. Although some enzymes (alkaline phosphatase, 5-nucleotidase and ATPases) have an almost uniform reactivity by the several taste buds, the other ones react with a lesser intensity in the smaller uniform reactivity by the several taste buds, the other ones react with a lesser intensity in the smaller taste buds of the fungiform papillae. As a rule the apical part of the cells shows a stronger enzymatic reactivity. The taste buds of the marmosets are penetrated by acetylcholinesterase positive nerve fibers whereas the autonomic ganglia in the connective tissue contain both-acetyl and butyrylcholinesterase.

The enzymatic changes in chronic hypertrophic rhinitis were studied in 14 patients. The cholinesterase content was increased in the subepithelium and stroma, denoting parasympathetic hyperactivity. Acid phosphatase was increased in the epithelium, subepithelium and around the glands, indicating increased shedding and phagocytic activity. Succinic dehydrogenase, alkaline phosphatase and alpha-esterase were increased in the mucous glands, denoting increase secretory activity, hence increased natural defence mechanism of the nasal mucosa.

Localization and activity of five hydrolases (alkaline phosphatase, adenosine triphosphatase, acid phosphatase, nonspecific esterase and leucylamino-peptidase) were evaluated histochemically in the epididymides of mature dogs. In the ductuli efferentes, cilia and apical parts of the epithelial cells displayed high activity of alkaline phosphatase and adenosine triphosphatase. Strong activity of acid phosphatase, nonspecific esterase and leucylamino-peptidase was present in the basal and supranuclear zones of the epithelium of the ductuli efferentes. Stereocilia of all three segments of the ductus epididymidis showed a high activity of alkaline phosphatase. Positive adenosine triphosphatase reaction was confined to the stereocilia of the initial segment. A complex pattern of acid phosphatase activity was observed in the middle segment. The subdivision of the middle segment in four subsegments was therefore suggested. In the epithelium of the initial segment only a few nonspecific esterase-positive cells were seen. The infranuclear and basal areas of the epithelium in the middle segment and the supranuclear zone of the terminal segment displayed distinct nonspecific esterase activity. The possible contribution of the hydrolases to the function of the epididymis is discussed.

Results on morphologic and hematologic characterization of a hamster leukemia capable of both cellular and cellfree transmission are described. Solid tumors removed in the course of several passages of leukemia animals, after producing blood smears, and spleen, liver, lymph nodes, bone marrow, thymus, kidney and lung were investigated histologically and histochemically. The morphological picture of the hamster leukemia has not changed during several transplantation generations. In addition to solid tumours, typical leukemic infiltration were detected histologically in spleen, liver, lymph nodes, bone marrow, kidneys and lung. No leukemic proliferation was noticed in the thymus. The final stage of the disease is characterized by an abrupt occurrence of high leukemic cell counts. The demonstration of alkaline phosphatase, but especially of naphtol-AS-D-chloroacetate esterase, in the leukemic cells is interpreted as indicating malignization of cells of the granulocytic line.

The purification of the pregnancy zone protein by means of immunoadsorbents is described. The pregnancy zone protein antibody was isolated from an absorbed rabbit antiserum and coupled with CNBr-activated sepharose. The pregnancy zone protein was isolated from pregnancy serum by the specific antibody cross-linked with sepharose. Contaminating serum proteins were eliminated by "inverse" immunoadsorption using antibodies against these proteins coupled with sepharose. An immunoelectrophoretically pure pregnancy zone protein was obtained. By means of a combination of immunoprecipitation and enzyme reaction in agar gel could be excluded that the pregnancy zone protein possesses activities of the following 11 enzymes: ceruloplasmin, leucine amino peptidase, alkaline phosphatase, carboxylic esterase, lactate dehydrogenase, malate dehydrogenase, glycerophosphate dehydrogenase, glucose-6-phosphat-dehydrogenase, cholinesterase, acetyl cholinesterase and oxytocinase.

Thirty-five ovarian tumors were examined (7 granulosa-cell tumors, 2 thecomas, 4 dysgerminomas, 6 mucinous cystadenomas, 10 serous cystadenomas, 2 adenocarcinomas, 3 Krukenberg tumors and 1 early embryonic tumor). The granulosa-cell tumors showed high activity of alpha-glycerophosphate dehydrogenase, and the changed cells of their stroma--that of glucose-6 phosphate and isocitrate dehydrogenases. The activity of the latter enzymes was striking also in thecomas. Dysgerminomas showed high alkaline phosphatase, acid phosphatase and nonspecific esterase activities. The authors emphasize the role of stromal cells in the hormonal activity of ovarian neoplasms.
