    Effects of some anti-rheumatic agents on copper-catalyzed thermal aggregation of gamma globulin (1979)

    Notes: Abstract Gerber has shown that specific anti-rheumatics,d-penicillamine and aurothiomalate, inhibit coppert(II)-catalyzed thermal aggregation of human gamma globulin. Various anti-rheumatics were tested for the activity. Steroidal and non-steroidal anti-inflammatory agents were almost ineffective, while a new non-steroidal anti-inflammatory agent, TAI-284 (6-chloro-5-cyclohexyl-1-indancarboxylic acid), was found to be one half as active as aurothiomalate. The structure-activity relationship of TAI-284 derivatives and the mode of action of TAI-284 were investigated.

    Evidence that glucagon stimulates insulin secretion through its own receptor in rats (1995)
    Springer

    Notes: Summary Since glucagon-like peptide-1 (7–36) amide (7–37) (GLP-1) has been found to be a potent insulinotropic hormone, it has been postulated that glucagon stimulates insulin secretion from islet beta cells through the GLP-1 receptor. We therefore examined the effects of a GLP-1 receptor antagonist, exendin (9–39) amide, on glucagon- or GLP-1-stimulated insulin release from isolated perfused rat pancreas. When infusion of 100 nmol/l exendin (9–39) amide was started 5 min before that of 1 nmol/l glucagon, the stimulation of insulin release by glucagon was similar to that found in the control situation (preinfusion with vehicle alone). By contrast, when 0.3 nmol/l GLP-1 was used in the same experimental setting, exendin (9–39) amide clearly inhibited insulin release. These results indicate that glucagon stimulates insulin release mainly through glucagon receptors but not GLP-1 receptors on islet beta cells. [Diabetologia (1995) 38: 274–276]

    Ultracytochemical study of capillary Ca2+-ATPase activity in brain edema (1989)

    Notes: Summary To investigate the functional relationship between astrocytes and Ca2+-ATPase of cerebral capillary endothelial cells (capillary Ca2+-ATPase), cold lesions were produced and the cytochemical reaction (CR) for Ca2+-ATPase activity and morphological changes of astrocytes were chronologically studied. Under normal conditions, CR for capillary Ca2+-ATPase activity was mild. However, at 20 min after the operation, astrocytic end-feet embracing the capillaries were swollen, and CR was moderate. Deposits of slightly coarsened reaction product (RP) appeared and accumulated on the abluminal surface. CR became stronger as edema fluid accumulated. At 4, 7 and 15 days, detachment of the astrocytic processes from the capillary wall was observed and in the uncovered capillaries, CR was intense, especially on the abluminal surface. It could be thus possible that the enzyme was related to the blood-brain barrier (BBB). At 2 months, reactive astrocytes has recovered lesionresistant capillaries. CR was mild and its associated deposits were coarser, the number decreasing on both surfaces. The nature and localization of the deposits of RP in the scar were different from those under normal conditions, possibly due to the functional differences between normal and reactive astrocytes in the BBB. CR was mild in association with astrocytes embracing the capillary wall and was intense without astrocytes. Therefore, it might be possible that astrocytes exerted certain effects on capillary Ca2+-ATPase activity in relation to BBB function.

    Neuroendocrine markers in central nervous system neuronal tumors (gangliocytoma and ganglioglioma) (1989)

    Notes: Summary We studied five cases of central nervous system neuronal tumor, one gangliocytoma and four gangliogliomas, both ultrastructurally and immuno-histochemically, using antibodies to neuroendocrine markers including tyrosine hydroxylase (TH), serotonin (5HT), somatostatin (SOM), met-enkephalin (MEK), leu-enkephalin (LEK), substance P (SP), gastrin, vasopressin, oxytocin, vasoactive intestinal polypeptide, adrenocorticotropic hormone and calcitonin. In all cases, the presence of dense-core vesicles (60–250 nm) in the neuronal elements was the characteristic ultrastructural finding. Synapses were observed in two cases. Immunohistochemically, variable numbers of neuronal cells showed positive staining for SOM in five cases, TH, MEK and LEK in three cases, and 5HT and SP in one case each. The others were negative. Positive immunoreactivity for multiple markers was shown in all cases. SOM, TH, 5HT and SP were present in the small- to medium-sized cells, while MEK and LEK were almost exclusively confined to the large cells. Our study clearly indicated that these tumors contained neuronal cells which were not homogeneous with regard to neuroendocrine markers.

    Notes: Summary Ca2+-ATPase activity on the astrocyte plasma membrane was investigated ultracytochemically, using the lead salt technique. Normal astrocytes showed a weak cytochemical reaction for Ca2+-ATPase activity, deposits of the reaction product being small. At 7 and 15 days after cold lesioning, reactive astrocytes apparently in the process of repair of the edematous lesion were observed; these demonstrated an intense cytochemical reaction for Ca2+-ATPase activity in their plasma membranes facing the extracellular fluid, with reaction product accumulation. At 2 months, the lesion had progressed to glial scars containing sporadic microcysts. The reactive astrocytes surrounding the microcysts demonstrated a moderate cytochemical reaction for Ca2+-ATPase activity in their free plasma membranes, whereas those arranged in a cell-to-cell pattern showed little reaction product in their plasma membranes. In conclusion, a more intense cytochemical reaction was always observed in the free plasma membrane of reactive astrocytes.

    Notes: Boss forming, which is sometimes called hub forming, has attracted its attention as anenvironment-friendly rotary forming process to form a circular plate with a hole into a boss shape.An experimental study was conducted to survey the technological possibility of boss forming. Bossforming of A1050-O commercially pure aluminum plate of 10 mm thickness was carried out atroom temperature under various working conditions. The effects of the working conditions on themetal flow in boss forming were clarified experimentally

    Effect of occlusion on human skin (1995)

    Topics: Medicine
    Notes: In order to investigate the el led of occlusion on the skin, the flexor sides of both upper arms were covered with column-shaped closed chambers, 30 mm in outer diameter. 20 mm in inner diameter. and 5 mm in height, which were made of polyethylene loam. The tops of the chambers were sealed be plastic films with various levels of water vapor permeability to control moisture in each chamber. The raised chamber walls prevented direct contact between the skin and the plastic film. After 24 h of application, morphological changes of the skin surface were observed microscopically by the nitrocellulose-replica method. Although no visual alterations were found on all areas of occluded skin, microscopic evaluation showed that simple occlusion by films induced an increase in the number of deepened skin furrows on the skin surface. This increase was associated with lower water vapor permeability of the films, as well as with higher values of both temperature and humidity on the test day. Thus, since conditions which facilitate perspiration from the skin lend to cause skin irritation, prolonged exposure of the skin to sweat by simple occlusion may act as a primary skin irritant
