The localization of non-specific alkaline phosphatase and cholinesterase activities evidenced in capillaries endothelium of the Rat brain have been compared in cerebral areas with or without the blood-brain barrier (BBB). There is a good topographical correlation: structures devoid of BBB (caudal part of the subfornical organ, choroid plexus, area postrema) do not display any non-specific cholinesterase activity with photonic microscope methods and an intense alkaline phosphatase activity; whereas structures with BBB (cortex, subcommissural organ, rostral part of the subfornical organ) show both enzymatic activities. At the ultrastructural level, more sensitive methods allow to disclose a non-specific cholinesterase activity in the reticulum endoplasmic cisternae and in the nuclear membrane in all endothelial cells. Alkaline phosphatase activities are present in the capillaries endothelium and in the conjonctive cells of pericapillaries spaces which exist in the circumventricular organs. Besides, these activities are closely related with the lateral and basal plasmalemmas of the choroidal cells responsible for the blood-cerebro-spinal fluid barrier. The apical plasmalemma is almost devoid of enzymatic activity. This result confirms the noticeable polarity of the choroidal cells, both morphologically and cytochemically.

The structure and histochemistry of the palmar and plantar skin were studied in four adult male marmosets (two Callithrix jacchus and two Callithrix penicillata). In this skin there exist well-developed epidermal ridges, to which are attached one or two ducts of sweat glands. A thick stratum corneum can be seen in the epidermis, while a distinct stratum lucidum cannot be isolated from the other layers. The stratum granulosum is constituted by one or three layers of cells containing keratohyalin granules. Melanin granulations are mainly concentrated in the basal cells of the epidermal ridges. Dendritic melanocytes and amelanotic melanocytes containing alkaline phosphatase are found among the epidermal cells. Glycogen, UDPG-GT and phosphorylases are mainly present in the middle and lower Malpighian cells of the epidermal ridges. Alkaline phosphatase, ATPase, alanyl amino-peptidase and leucine aminopeptidase were absent in the epidermal cells. SDH, cytochrome oxidase, MAO and a certain number of NAD-dependent dehydrogenases (LDH, ADH, MDH, alpha-GPDH, beta-OHBDH and GDH) showed a stronger reactivity in the basal cells and Malpighian layer. The NADP-dependent enzymes (G-6-PDH, 6-PGDH, cis-aconistase and ICDH) were more reactive in the upper Malpighian layer and stratum granulosum. The stratum corneum showed some acid phosphatase and nonspecific esterase reactivity. The collagenous fibers intertwined with a small number of very thin elastic ones and a larger amount of reticular fibers run almost parallel to the epidermal ridges in the papillary body. In the reticular dermis some fibers are disposed transversely to the epidermal ridges. Meissner corpuscles reactive to butyrylcholinesterase, acetylcholinesterase, nonspecific esterase and G-6-PA are disposed at regular intervals and frequently at each side of the epidermal ridges. Pacinian corpuscles were found only in the hypodermis. The eccrine sweat glands contain glycogen, UDPG-GT and phosphorylase in their secretory, ductal and myoepithelial cells. The secretory part shows a uniform reactivity for every dehydrogenase because it contains only one type of cells (clear cells). The intraepidermal segment of the ducts shows a stronger reactivity to nonspecific esterase and NADP-dependent dehydrogenases than the epithelial cells around it.

Thirty patients suffering from active intestinal S. mansoni infection, were classified into 3 groups. The first group: 13 cases with early active intestinal schistosomiasis without hepatosplenomegaly. The second group: 11 cases with hepatosplenomegaly and the third group: 6 cases with splenomegaly and ascites. Also 10 normal individuals were included as a normal control group. Histopathological examination of rectal mucosa showed hyperaemia with extravasation of blood in early cases and granulomatous lesions in the second group with hepatosplenomegaly. The structural changes were severe in the late ascitic group. In this group the rectal mucosal glands showed distorted irregular tubular branching in addition to the granulomatous and the fibrous reactions. Histochemical studies including periodic acid schiff, alkaline phosphatase and acetyl cholinestrase reactions were done. Using the periodic acid shiff stain, the goblet cells showed strong reaction for neutral mucin in cases of group I (early cases) and group II (late hepatosplenomegalic cases). In group III (late ascitic cases) the goblet cells were faintly stained. A notable difference was observed between the lightly and heavily infected patients of this group. No alkaline phosphatase reactivity could be identified in rectal crypts of patients and controls. Alkaline phosphatase reactivity was sharply localised in S. mansoni egg shell. There was obvious decrease in the acetyl cholinesterase stained nerve fibres in the rectal mucosa of all studied patients. The decrease was more in chronic and heavily infected cases rather than in the acute and lightly infected ones.

The enzymic activity of blood of healthy male volunteers was examined during 8-day bed rest in the horizontal and head-down (-6 degrees) position, water immersion up to the neck and 6-hour head-down tilt (-15 degrees). Alkaline phosphatase, cholinesterase (CE), leucine arylamidase (LA), glutamate dehydrogenase (GDH) and gamma-glutamyl transpeptidase (GGTP) were measured. During horizontal bed rest the activities of all the enzymes, except for GDH, decreased in a moderate degree which was very distinct at an early stage of exposure. The activity of GDH and CE decreased significantly after the exposure. The enzymic activity tended to decline during head-down tilt at -6 degrees. The LA and GGTP activity decreased to a greater extent, being statistically significant during head-down tilt at -6 degrees and in the recovery period. The enzymic activity insignificantly increased during water immersion and 6-hour head-down tilt at -15 degrees, remaining in some cases elevated during 5 days after exposure. The lower activity of enzymes (which was significant for some of them) during horizontal and antiorthostatic bed rest was primarily associated with diminished motor activity, whereas increased enzymic activity was related to the gravity-induced blood shift to the intrathoracic area.

Eight hematologic parameter values, 16 serum biochemical constituents, serum protein fractions and albumin-globulin ratios were determined in blood samples obtained from 879 normal, healthy Beagle dogs of both sexes which had been reproduced and bred in our laboratories. The blood samples were collected from the Beagles that ranged in monthly ages from 1 to 12 and in monthly ages from 13 to 121, which were classified as the adult class. As a result, red blood cell counts, hemoglobin concentrations and packed cell volumes increased with growth. Red blood cell parameters of normal Beagles in our laboratories were rather higher than those in literatures presented by many other researchers. MCV decreased and MCHC increased gradually with age. Total serum protein concentrations increased with growth. alpha 1-1 and alpha 1-2 Globulin fractions descended, but beta 2 and gamma globulin fractions ascended in serum proteins. Alkaline phosphatase activities, inorganic phosphorus concentrations and glucose concentrations decreased conspicuously with growth. Leucine aminopeptidase activities and calcium concentrations decreased slightly. Serum cholinesterase and LDH activities showed a tendency to diminish similarly. Blood urea nitrogen and creatinine concentrations multiplied gradually. Hematologic parameters became almost steady in our 7-month-old dogs or older ones and serum biochemical constituents had a tendency to be stable in our 7- to 9-month-old dogs or older ones in the blood. White blood cell counts, alkaline phosphatase activities, inorganic phosphorus concentrations, glucose concentrations, leucine aminopeptidase activities and calcium concentrations were lowest in the adult class.

1. The action of beryllium on the following enzymes has been examined: alkaline phosphatase (Escherichia coli and kidney), acid phosphatase, phosphoprotein phosphatase, apyrase (potato), adenosine triphosphatase (liver nuclei, liver mitochondria, brain microsomes), glucose 6-phosphatase, polysaccharide phosphorylases a and b, phosphoglucomutase, hexokinase, phosphoglyceromutase, ribonuclease, A-esterase (rabbit serum), cholinesterase (horse serum), chymotrypsin. Alkaline phosphatase and phosphoglucomutase are inhibited by 1mum-beryllium sulphate whereas the other enzymes are largely unaffected by 1mm-beryllium sulphate. 2. Possible mechanisms for the inhibition of phosphoglucomutase and alkaline phosphatase are discussed.

The enzymatic changes in tertiary nasal syphilis were studied in 5 patients. The cholinesterase was increased in the subepithelium, around the glands and blood vessels, denoting parasympathetic hyperactivity. Acid phosphatase was increased in the epithelium, stromal histiocytes, around the glands and ducts, indicating increased phagocytotic activity. Alkaline phosphatase was increased in the capillary endothelium and periglandular stroma, denoting marked vascular changes. Succinic dehydrogenase, alkaline phosphatase, alpha esterase and PAS-alcian blue were diminished in the epithelium and glands, denoting diminished secretory activity, hence a diminished natural defence mechanism of the nasal mucosa. When serological tests are inconclusive, these findings become an important adjuvant to a final diagnosis.

Reference intervals for some clinical chemistry parameters in the marmoset were calculated. The effects of age (250-300 days compared with 500-550 days) and sex on the values found was investigated. Alkaline phosphatase levels decreased with age, young males having higher plasma levels than young females, but no sex differences were discernible for older animals. Levels of gamma-glutamyl transpeptidase and sorbitol dehydrogenase were higher in older males than in younger females. Higher plasma iron levels were found in the males with increasing age. Age and sex effects for protein and albumin were interactive and further interpretation was therefore difficult. No significant age or sex effects were seen for cholinesterase, acetylcholinesterase, isocitrate dehydrogenase, malate dehydrogenase, lactate dehydrogenase, glutamate dehydrogenase, aspartate amino transferase, alanine aminotransferase or bilirubin.

Activities of 14 enzymes were determined in psoas muscle, smooth muscle, diaphragm, heart, brain, liver, kidney, spleen, pancreas, salivary glands, zygomatic gland, intestinal mucosa, subcellular fractions, and plasma of the dog. In pups, plasma activity of most enzymes was high, except iditol dehydrogenase (ID), glutamate dehydrogenase (GLD), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and D-fructose-1,6-diphosphate aldolase (ALS). Alkaline phosphatase (ALP), ALS, cholinesterase (CHS), creatine kinase (CK), alpha-hydroxybutyrate dehydrogenase (HBD), lactate dehydrogenase (LD), and malate dehydrogenase (MD) decreased significantly (P less than 0.01) with increasing age, but in dogs greater than 7 months, all enzymes except CK, HBD, and ALT revealed reasonably constant plasma values. Enzymes ALT, GLD, CHS, and ID are specific for liver, CK and ALS for muscle, HBD to some degree for myocardium, and alpha-amylase for pancreas. The ALP and gamma-glutamyltransferase were located in microsomes, GLD in mitochondria, MD and AST in mitochondria and cytoplasm, and isocitric dehydrogenase, LD, and the other enzymes only in cytoplasm.
