    Notes: Summary A 59-year-old woman presented with milia grouped in plaques, in the preauricular areas, bilaterally. Follicle-damaging dermatoses, tumours and external agents, can lead to this peculiar clinical pattern. We outline the clinical and histological features which allow accurate diagnosis of this condition.

    The inhibitory effect of phenothiazine stains on rat and guinea-pig mast cell damage induced by antihistamines and compound 48/80 (1973)

    Notes: Summary 1. Toluidine blue inhibits rat mesentery mast cell disruption induced by compound 48/80 and by the antihistamine drugs chlorcyclizine and diphenhydramine. 2. Glucose reverses the blocking action of toluidine blue. Calcium does not. 3. In the guinea-pig mesentery, mast cell damage induced by promethazine is inhibited by toluidine blue. Glucose does not reverse this blocking action. Damage by compound 48/80 is not inhibited. 4. Two other phenothiazine stains—methylene blue and thionin—also inhibit rat mesentery mast cell damage by compound 48/80. For its inhibiting action thionin requires a much lower concentration than the other two dyes. 5. The action of methylene blue and thionin on rat mast cells is influenced by the pH of the incubation medium. Much higher concentrations of these stains are needed to protect mast cells from the action of compound 48/80 when the pH is lowered from 8.4 to 7.0. Toluidine blue, however, is not influenced by pH changes. 6. “In vitro” staining of mast cells with methylene blue and thionin is also influenced by pH. At 8.4 the cells are well stained, while at 7.0 they are barely stained at all. 7. It is concluded that phenothiazine stains block mast cell damage by inhibiting cell metabolism. Therefore, besides its lytic action, antihistamines must also act through an energy-requiring process similar to that of compound 48/80. In the guinea-pig, promethazine damages mast cells through a mechanism different from that of compound 48/80, although both are non energy-requiring. Either in the rat or in the guinea-pig the phenothiazine stains do not seem to inhibit the action of mast cell damaging agents by blocking their access to the active cell sites.

    A novel granular cell type of locust Malpighian tubules: ultrastructural and immunocytochemical study (1992)

    Notes: Summary A novel secretory cell type in the initial segment of the Malpighian tubules of the locusts Schistocerca gregaria and Locusta migratoria is described ultrastructurally and studied by means of immunocytochemical techniques. The cells show abundant rough endoplasmic reticulum with interspersed Golgi zones. The richness of the cell secretory machinery and the presence of apical dense plemorphic granules suggest a role in secretion of proteinaceous material to the tubule lumen. The surprising finding of ACTH (1–24)-, α-MSH-, and 7B2-like immunoreactivity for this cell is discussed.

    Presence of Locusta diuretic hormone in endocrine cells of the ampullae of locust Malpighian tubules (1996)

    Notes: Abstract. This is an investigation of an endocrine cell type in the midgut of the migratory locust Locusta migratoria. This cell type is found in the posterior region of the midgut and is especially common in the ampullae through which Malpighian tubules drain into the gut at the midgut-hindgut junction. Strong Locusta diuretic hormone-like immunoreactivity in these cells was colocalized with FMRFamide- and substance P-like immunoreactivities. At the ultrastructural level, immunoreactivity for Locusta diuretic hormone was found in spherical granules (mean diameter of 450 nm), the contents of which showed variable electron density. Fractionation of a methanolic extract of the ampullae by reversed-phase high performance liquid chromatography revealed the presence of two peaks of Locusta diuretic hormone-like immunoreactive material, both of which stimulate cyclic AMP production by isolated Malpighian tubules. The more hydrophobic material is most likely Locusta diuretic hormone, which has the same retention time when chromatographed under identical conditions.

    Inguinal hernia and certain risk factors (1992)
    Springer

    Notes: Abstract The are several studies on inguinal hernias that give some clues about the association between this type of hernia and certain risk factors. This association was suspected long ago but had not been demonstrated. The present study tries to correlate the origin of inguinal hernias and the physical effort of the subjects in accordance with their work activity. The results of this study show that physical effort, as a risk factor, is closely related to the appearance of inguinal hernias. A person whose work involves lifting or other strenuous exertion has a higher risk than those whose jobs are less stenouous (p 〈 0.05). This conclusion was reached after taking into account not only the weight lifted but also the number of years in this activity.

    Microstructural evolution of annealed Al–5 wt% Ca–5 wt% Zn sheet alloy (1997)

    Notes: Abstract Microstructural evolution on annealing of Al–5 wt% Ca–5 wt% Zn sheet alloy has been systematically investigated by means of texture analysis and optical and transmission electron microscopy. Heat treatments in the temperature range of 100 to 540 °C for times between 0.11 (7 min) and 90.5 h have been performed. After annealing, the main texture component of the as- received material, {1 1 3} 〈3 3 2〉, was retained, whereas the minor components, {0 1 3} 〈3 1 0〉 and {0 1 1} 〈1 0 0〉, showed clear changes depending on the annealing conditions. Additional minor components appeared upon heat treatments. Continuous recrystallization, subgrain accommodation by means of rotation and subsequent extensive grain growth are the processes which account for all the microstructural changes observed.
