    Notes: Summary Exercise-induced anaphylaxis (EIA) is a form of physical urticaria that is induced by exercise. A 16-year-old Japanese boy had a 4-year history of recurrent wealing and dyspnoea after physical exercise such as jogging, playing handball or riding a bicycle in winter. The episodes were not associated with ingestion of foods including wheat or soya bean. A provocation test, with 15 min of exercise and 2 min of cold stimulation immediately before or immediately after the exercise, elicited a weal that was localized to the test area. A challenge test with ingestion of boiled soya beans and exercise did not elicit a weal. Therefore, in this case, cold exposure, but not food ingestion, was essential for inducing EIA. Cold-dependent EIA is different from cold urticaria, food-dependent EIA, cholinergic urticaria and cold-induced cholinergic urticaria, and may be a distinct entity.

    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.

    Notes: Use of a monoclonal antibody against Lafora bodies for the immunocytochemical study of ground-glass inclusions in hepatocytes due to cyanamide Aims: Ground-glass inclusions (GGIs) in hepatocytes are known to be associated with cyanamide treatment in patients with alcohol dependency. The purpose of this study was to assess the reactivity of a monoclonal antibody (MAb) raised against polyglucosan and to detect early events in GGI formation. Methods and results: Formalin-fixed paraffin-embedded liver tissues from four patients treated with cyanamide were used. Sections were stained with haematoxylin and eosin and periodic acid–Schiff with and without diastase digestion, and were immunohistochemically stained with the MAb. For electron microscopic study, routinely processed liver tissue from one patient was examined with conventional and immunoelectron microscopy with use of the MAb. All specimens from the four cyanamide-treated patients contained GGIs in the cytoplasm of hepatocytes, and these GGIs reacted intensely with the MAb. Fully developed GGIs contained various organelles, whereas early ones consisted primarily of glycogen granules and dilated smooth endoplasmic reticulum. In immunoelectron microscopic preparations, gold particles were located within GGIs, and the immunolabelled organelles appeared to be glycogen granules. Conclusions: This novel MAb is useful for the detection of GGIs caused by cyanamide. Our results support the idea that GGI formation may result from specific abnormalities in glucose metabolism.

    Notes: Summary Darier's disease is an autosomal dominant skin disorder that is characterized by multiple keratotic papules, focal loss of adhesion and abnormal keratinization. Mutations in the ATP2A2 gene encoding sarco/endoplasmic reticulum calcium pumping ATPase type 2 have been identified as the molecular basis of Darier's disease. Segmental Darier's disease is a rare type of Darier's disease in which there is characteristic localization of the keratotic papules in a linear pattern following Blaschko's lines. In this study we examined ATP2A2 mutations in a Japanese patient with segmental Darier's disease. The samples from affected skin, unaffected skin and peripheral leucocytes were subjected to polymerase chain reaction (PCR). Direct sequencing of the PCR products was performed. Sequence analysis revealed that the patient had 160A→G substitution mutation which predicts I54V. This novel mutation was present in the affected skin, but not in the unaffected skin or peripheral leucocytes. This is the first report of segmental Darier's disease caused by mosaicism for an ATP2A2 mutation in Japan.

    Notes: Summary On the basis of the amino acid composition of the chromophore peptides, it can be assumed that Asp, Ser and 1/2 Cys are located near the biliverdin chromophore. Experiments for splitting of the chromophore lead us to expect a thioether bond in the linkages between biliverdin and apoprotein.

    Notes: Summary Cordycepin (3′-deoxyadenosine) inhibited viral RNA synthesis in the replication of western equine encephalitis virus, thereby causing a reduction of virus production. The rate of inhibition of viral RNA synthesis was dependent on drug concentration and the period of treatment with the drug. These results suggest that the virus RNA synthesizing system is sensitive to the drug.

    Notes: Summary The defective step of a temperature-sensitive mutant of western equine encephalitis virus, which synthesize viral RNA but not mature virus at the restrictive temperature, was studied. Cells infected with the mutant virus at the restrictive temperature synthesized the same intracellular viral RNA as that in wild type infection. Cells infected with the mutant at the restrictive temperature formed three proteins (E1, E2 and C) which migrated to positions identical with those of purified virions and a precursor protein of E2 (PE2). The mutant virus was also able to form cytoplasmic nucleocapsids sedimenting at 140S as in the case of wild type infection. On the other hand, cells infected with the mutant could not induce a significant amount of hemadsorbing ability and the ability induced at the permissive temperature disappeared immediately after shifting up to the restrictive temperature. These results suggested that the mutant virus produced a defective envelope protein responsible for hemagglutination at the restrictive temperature. Owing to the incompleteness of the modification of the cell plasma membrane by the envelope proteins, viral nucleocapsids in the mutant infected cells could not bind to the plasma membrane.
