    Notes: Summary A total of 18 hemagglutinating agents were isolated from 14 of 278 migrating feral ducks in Hokkaido during the surveillance studies conducted from 1978 to 1981. Seven of the 18 isolates belonged to paramyxovirus and the rest to influenza A virus. Five isolates of paramyxovirus reacted specifically with antiserum to duck/HK/199/77 and 7 isolates of influenza A virus possessed the antigenic configuration of H10N3. Three of the isolates possessed an hemagglutinin that has no antigenic relation to any of the 26 known strains of avain, swine, equine and human influenza A viruses.

    Relationship between structure, positive inotropic potency and lethal dose of grayanotoxins in guinea pig (1980)

    Notes: Abstract Relationship between chemical structure, positive inotropic potency and lethal dose of grayanotoxins and the related compounds was studied using guinea pigs. The positive inotropic effect (PIE) was examined in their papillary muscle isolated from the heart.The potency of these compounds was expressed by pD2 values, and was determined by depicting the concentration-PIE curve for each compound. The study has clarified the contribution of functional groups in the molecule; the presence of 3β-hydroxyl, 6β-hydroxyl and 10β-methyl groups attached to the grayanane skeleton is established to be essential for the development of PIE. The inotropic potency of compounds carrying these essential groups is increased by a 10α-hydroxyl group and the acylation of the 14β-hydroxyl group. LD50 value of 10 compounds with a high cardiotonic potency (pD2〉4) was determined by up and down method using male guinea pigs. The relation of LD50 to pD2 bore a significant correlation (r = 0.68, p〈0.05). The most cardiotropic and toxic compound found in this study was asebotoxin III.

    Innervation of dog ciliary ganglion (1982)

    Notes: Summary There are species differences with regard to the composition of the ciliary ganglion. For instance, in rabbits and cats it consists solely of oculomotor nerves and has no sympathetic or sensory innervation. The purpose of this study is to clarify the participation of these nerves in the ciliary ganglion of the dog by histochemical methods. Cholinesterase (ChE) activity was studied by Karnovsky's method and catecholamine fluorescence by the glyoxylic acid method. Furthermore, the origins of the respective nerves were investigated by a serial preparation method, involving unilateral cervical sympathectomy and tracer dye injection in the ganglion. The results obtained were: (1) Ciliary ganglion cells showed intense ChE activity. Oculomotor nerve fibers leading to the ganglion showed moderate ChE activity, while the reaction in the short ciliary nerves was strong. (2) Aminergic nerves were present in the intercellular space of the ciliary ganglion, and bilateral or central innervation was suggested by the results of cervical sympathectomy. (3) Connection between the ciliary and trigeminal ganglia was proved by the dye tracer study. The results show that the ciliary ganglion in dogs is composed of oculomotor, trigeminal and sympathetic nerves.

    Histochemical studies on the postnatal development of autonomic nerves in mice cerebral arteries (1981)

    Notes: Summary Postnatal development of autonomic nerves of major cerebral arteries was histochemically studied in mice from one day to five months of age. For demonstration of aminergic nerves the glyoxylic acid method was used, while for cholinergic nerves Karnovsky and Roots' technique was utilized consecutively on the same whole mount preparations. The results obtained were as follows: 1) In one-day-old mice a few aminergic nerves were seen while cholinergic nerves were scarcely observed. The cholinergic nerves were clearly observed in one-week-old mice. Then, both nerves increased rapidly in the first 2 weeks with a slight delay of maturation in the latter. They completed development between 3 and 4 weeks. 2) Longitudinal and circular distributional patterns were observed for the both nerves; the former pattern developed earlier than the latter.

    Vasoactive intestinal polypeptide immunoreactive and cholinergic nerves in the whole mount preparation of the major cerebral arteries of the rat (1983)

    Notes: Summary An immunofluorescence histochemical study of vasoactive intestinal polypeptide (VIP) was made in the major rat cerebral arteries of the whole mount preparation. A comparison was made between the distribution of VIP-immunoreactive and cholinergic nerves. An abundant number of VIP-containing nerves were observed in the internal carotid, anterior cerebral, middle cerebral and basilar artery. VIP and cholinergic nerves were unaffected by bilateral superior cervical ganglionectomy. The density and distribution of VIP-immunoreactive fibers was essentially the same as that of the cholinergic fibers of the rat cerebral vasculature. It is suggested that, as was previously demonstrated in other peripheral organs, VIP coexists within cholinergic neurons of the rat cerebral arteries.

    Notes: Summary A consecutive demonstration of both aminergic and cholinergic nerves of rat cerebral arteries was carried out on whole mount preparations. For demonstration of aminergic nerves the glyoxylic acid method was used, while for cholinergic nerves Karnovsky's technique was utilized consecutively. This procedure provided a highly sensitive and reproducible demonstration of the two systems on the same specimen. The results obtained were as follows: 1) Aminergic and cholinergic nerves were distributed densely in the proximal portions of the major cerebral arteries examined. They were dense in the arteries of the anterior circulation and sparse in the posterior circulation. Each nerve had two different patterns, i.e. circular and longitudinal. Both circular and longitudinal patterns were observed in the proximal portions of the arteries, while in the distal portions, longitudinal fibres were predominantly present. 2) Superior cervical ganglionectomy produced no change in cholinergic nerve distribution, while it caused decreased density of aminergic nerves on the ipsilateral side on the arteries of the anterior circulation. The contralateral anterior cerebral arteries were partially affected. Bilateral sympathectomies abolished aminergic nerves in all arteries except the vertebral artery.
