    Monilethrix: an ultrastructural study (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of cutaneous pathology 11 (1984), S. 0

    Notes: Characlcristic moniliform hairs of monilcthrix were ultrastructurally examined. By scanning electron microscope, nodes and internodes were seen alternating on the affected hair; the nodes were normal in apparance and thickness, while the internodes were thin and showed ridges and flutes. By transmission electron microscope, the cross sections of the internodes revealed wrinkling of the hair coticular cells and a reduced number of the cortical cells. Cross sections of the cortical cells per se showed a similar size and a normal keratin pattern in both nodes and internodes, compared with those of control hairs from normal individuals. From these findings, the internodes seemed to be the pathological portions of the monilifonn hair, and such abnormal thinning of hair shaft might tie caused by a periodical dysfunction of the hair matrix, especially in the hair cortex.

    Large melanoacanthomas: a report of five cases (1984)

    Topics: Medicine
    Notes: Five patients with mclanoacanthonia are reported. The skin lesions consisted of a single, round plaque measuring several centimeters in diameter. Histologic findings were characterized by formation within an acanthotic epidermis, of many islands of small basaloid cells and highly dendritic melanocytes. Electron microscopic examination of one lesion revealed a disturbance of melanin transfer from the highly dendritic melanocytes to the neighboring keratinoeytes.

    Asymmetry in jaw-jerk reflex latency in craniomandibular dysfunction patients with unilateral masseter pain (2000)
    Oxford, UK : Blackwell Science Ltd
    Journal of oral rehabilitation 27 (2000), S. 0 
    Details
    ISSN: 1365-2842
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: The purpose of the present study was to elucidate the effects of unilateral masseter muscle pain on the jaw-jerk reflex. The latency and peak-to-peak amplitude of bilateral electromyographic activity recorded at the masseter muscles during the jaw-jerk reflex were measured in 18 patients with craniomandibular dysfunction (CMD) with strictly unilateral masseter pain or tenderness and 10 control subjects using a computerized recording and analysis system. The reflex was elicited, at the mandibular rest position, by tapping the centre of the chin downwards with a reflex hammer incorporating a microswitch that triggered the sweep of the recording apparatus upon contact with the chin. In the CMD group, the jaw-jerk latency on the affected side (6·89±0·98 ms) was significantly shorter (P〈0·01) than that on the unaffected side (7·59±0·92 ms). In the control group, there was no difference between the jaw-jerk latencies on the right (7·06±0·64 ms) and the left (7·08±0·65 ms) sides. The range of side asymmetry for jaw-jerk latencies in the CMD group was greater than that in the control group. In six patients, the latency difference exceeded 1 ms. The asymmetry of latency of the jaw-jerk reflex was thought to be due to facilitation on the side with masseter pain or tenderness. This facilitation on the ipsilateral side might be produced by enhanced gamma drive induced by sustained nociceptive stimulation. Such effects may be related with clinically derived concepts regarding such muscle dysfunction as myospastic activity or trigger points.

    The effect of corticosteroids, dapsone and gold upon plasminogen activator synthesis and secretion by human epidermal cells cultured with pemphigus antibody (1984)
    Oxford, UK : Blackwell Publishing Ltd
    British journal of dermatology 110 (1984), S. 0 
    Details
    ISSN: 1365-2133
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: Human epidermal cells were cultured with pemphigus antibody in the presence of hydrocortisone, methlprednisolone sodium succinate, dapsone and gold. Hydrocortisone and methylprednisolone reduced the production of the enzyme plasminogen activator but dapsone and gold had no effect. These results support the hypothesis that corticosteroids have dual effects on pemphigus through inhibition of plasminogen activator production by epidermal cells and suppression of pemphigus antibody production by B lymphocytes.

    Notes: Summary A toxin causing paralysis was detected in the starfishAstropecten latespinosus. The toxin was purified by a method consisting of charcoal treatment and chromatography on CM-Sephadex C-25 and Bio-Rex 70. The toxin was identified as tetrodotoxin by its behavior in thin-layer chromatography and electrophoresis and its1H-NMR spectrum.

    Inhibition of brain enolases by acrylamide and its related compounds in vitro, and the structure-activity relationship (1984)

    Notes: Summary Acrylamide and its related compounds inhibited brain enolases in vitro independently of their neurotoxicity. The inhibitory potency was a function of the binding constants of the compounds for phenylalanine. The binding constant for tryptophan was higher in neurotoxic compounds than in non-neurotoxic ones.

    Ebselen Decreases Ozone-Induced Pulmonary Inflammation in Rats (2000)
    Springer
    Lung 178 (2000), S. 225-234 
    Details
    ISSN: 1432-1750
    Keywords: Key words: Ozone—Pulmonary inflammation—Ebselen—Peroxynitrite.
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract. We studied the effects of ebselen on rat lung inflammatory responses against ozone exposure. Rats were treated with ebselen every 12 h from 1 h before a single 4-h exposure to 2 ppm ozone. Treatment with ebselen (10 mg/kg) significantly decreased pulmonary inflammation as indicated by the albumin concentration and the number of neutrophils in the bronchoalveolar lavage fluid 18 h after the ozone exposure. Although treatment with ebselen did not alter the macrophage expression of inducible nitric oxide synthase after the ozone exposure, it did markedly inhibit the nitration reaction of tyrosine residues, suggesting that ebselen scavenges peroxynitrite during ozone-induced pulmonary inflammation. Treatment with ebselen also enhanced the pulmonary expression of both copper, zinc, and manganous superoxide dismutases at the same time point. These enzymes may also contribute to a decrease in the formation of peroxynitrite by lowering the concentration of superoxide. Thus, ebselen represents a useful compound for protecting against certain acute lung injuries by modulating the oxidant-related inflammatory process.

    Topics: Medicine
    Notes: Summary Responses of ring segments of the isolated canine coronary artery superfused with arterial blood from a donor dog were compared with responses of segments superfused with Krebs-Henseleit (K-H) solution. KCl (1–30 mg) caused contraction in a dose-dependent manner both in K-H solution- and in blood-superfused preparation. However, CaCl2 (1–100 mg) and nifedipine (0.1–30 μg) contracted and relaxed, respectively, only blood-superfused preparation but not K-H solution-superfused one. These results show that even in the same region of the coronary artery, different superfusates result in different responses to contracting or relaxing agents. This difference may be explained by the idea that Ca2+-channels are activated and endow basal tension in blood-superfused preparations, but not in K-H solution-superfused ones.
