    Notes: : Based on the high level of extractability of myosin subunits (light chains), even after prolonged heat treatment of muscle, a new method to evaluate the dark muscle content in the fish meat and products of mackerel is proposed. Tissue-specific rabbit antisera with myosin light chains (A1 from ordinary muscle and D1 from dark muscle) from mackerel Scomber japonicus were obtained. Mackerel meat paste (surimi) was dissolved in 8 M urea containing 1% SDS, and diffused on agar plates containing antiserum against A1 or D1 by single radial immunodiffusion (SRID). The results obtained showed that the area of halos formed in the plates was quite proportional to the content of dark muscle.

    Notes: 1. Effects of calcitonin on dopamine-, secretin- and pancreozymin-induced pancreatic secretion were investigated in the isolated blood-perfused canine pancreas.2. The volume of pancreatic secretion induced by pancreozymin given intra-arterially (i.a.) was decreased by an i.a. infusion of 1 u/min of calcitonin, but that induced by dopamine or secretin given i.a. was not affected by calcitonin treatment.3. Amylase concentration in pancreatic juice either in spontaneous secretion in the resting state or in that of stimulated secretion by pancreozymin was decreased approximately 30% by calcitonin treatment, but amylase concentration in pancreatic juice induced by dopamine or secretin was not affected by calcitonin treatment.4. Calcitonin had no effect on bicarbonate concentration in pancreatic juice stimulated by these secretagogues.5. Calcium concentration in pancreatic juice in the resting state was reduced about 36% by calcitonin treatment. Calcitonin caused a decrease in a calcium concentration in the pancreozymin-induced secretion, but did not cause any change in the dopamine- or secretin-induced one.6. These results suggest that calcitonin may affect the secretory mechanism of the acinar cells but not that of the ductular cells, and that the acinar cells are active even in the resting state.

    Notes: 1. The effects of glucagon on the secretion of pancreatic juice were investigated using blood-perfused canine pancreas preparations.2. Intravenous administration of glucagon (3–30 μg/kg) to the donor dog elicited a dose-dependent increase in pancreatic secretion. Intra-arterial administration of glucagon (10–100 μg) into the perfused pancreas also elicited increased secretion.3. There were slight increases in amylase concentration of the pancreatic juice with the largest doses of glucagon given by either route.4. Glucagon-induced secretion was not modified by treatment with phentolamine, propranolol, atropine, guanethidine, tetrodotoxin, haloperidol, prostaglandin F2a or calcitonin.5. The results suggest that glucagon acts directly on the exocrine cells of the canine pancreas.

    Notes: 1. The antiarrhythmic properties of 5–(3-tert-butylarnino-2-hydroxy)propoxy-3,4-dihydrocarbostyril hydrochloride (OPC-1085) were compared with those of propranolol and pindolol using various kinds of preparations for experimental arrhythmia in dogs.2. Although OPC-1085 was the most potent drug to antagonize adrenaline-induced arrhythmia in animals anaesthetized with either pentobarbitone sodium or halothane, it was scarcely effective on ouabain-induced arrhythmia in pentobarbitone sodium anaesthetized animals.3. When these compounds were administered intravenously to conscious dogs 24 h after two-stage ligation of the anterior descending artery, ectopic ventricular beats of coronary ligation-induced arrhythmia were reduced while regular sinus beats were simultaneously increased.4. OPC-1085 was very effective on aconitine-induced arrhythmia in dogs anaesthetized with pentobarbitone sodium. The effective dose was similar to that of propranolol but about fifteen times less than that of pindolol.5. It is concluded that different potencies among these β-adrenoreceptor antagonists against various kinds of experimental arrhythmias cannot be simply deduced from any one of the following properties; β-adrenoreceptor antagonism, intrinsic myocardial stimulation, local anaesthetic and so-called quinidine-like effects.

    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: 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: 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: During starvation, counterregulatory responses to loss of food (i.e. responses that lead to an increase in appetite) occur in the central nervous system (CNS). This study was designed to examine whether middle-aged rats show greater or smaller behavioural, peripheral and central hormonal responses during starvation compared to young rats. In experiment 1, refeeding following 4 days of starvation was measured in both middle-aged (72-week-old) and young (9-week-old) rats. The level of refeeding was similar to each prestarved level until 3 days after the end of starvation in both groups. From the 4th day, the level of refeeding in young rats increased and reached beyond the prestarved level, whereas refeeding in middle-aged rats remained similar to the prestarved level. Thus, overall refeeding throughout 7 days was greater in young rats than in middle-aged rats. In experiment 2, middle-aged and young rats were starved for 4 days and were killed in the morning. Middle-aged rats showed a smaller plasma corticosterone response than that of young rats. The magnitude of decreases in plasma glucose, insulin and leptin was similar in both groups. In the arcuate nucleus, the starvation-induced increase in neuropeptide Y (NPY) mRNA and the decrease in proopiomelanocortin (POMC) mRNA were smaller in middle-aged rats than in young rats. In contrast, the starvation-induced decrease in corticotrophin-releasing hormone (CRH) mRNA in the hypothalamic paraventricular nucleus was greater in middle-aged rats than young rats. The magnitude of decrease in type-2 CRH receptor mRNA in the ventromedial hypothalamus was similar in both groups. The results indicate that (a) ageing impaired refeeding response (b), middle-aged rats showed the same directional neuropeptide mRNA responses as seen in young rats during starvation and (c) the magnitude of these counterregulatory responses in the CNS in middle-aged versus young rats was not uniform, but rather was site-specific or neuropeptide-specific. This study suggests the importance of NPY and POMC responsiveness in the arcuate nucleus in the age-related differences resulting from starvation-induced refeeding.
