    Notes: Abstract Of 12 different plant growth regulators (PGRs) tested,5-aminolevulinic acid (ALA) was found to improve the salttolerance of cotton seedlings. Cotton seedlings treated with ALAcould grow in soil containing levels as high as 1.5% (wt/wt)NaCl. The analyses of mineral compositions of plant parts revealed that the Naplus concentrations in the roots of the plantstreated with ALA were suppressed to low concentrations. Fromthese results, it can be presumed that the presence of ALA maycause a reduction of Naplus uptake.

    Notes: Abstract The role of 5-aminolevulinic acid (ALA) as a precursor of chlorophyll or a herbicide is well documented. In the present report, to elucidate the physiological effects of ALA, this compound was applied to the foliage of radish at 0.06, 0.18, 0.6, 1.8 and 6 mM. ALA at 0.06ndash;1.8 mM increased the dry weight of radish root (underground part), but injured radish seedlings at 6 mM. Also, the application of ALA at 0.18 and 0.6 mM increased fixation of CO2 in light and decreased release of CO2 in darkness. Furthermore, the effects of foliar treatment of ALA on the yield of several crops were also evaluated. The results showed that an application of ALA at low concentrations increased the growth and yield by 10ndash;60percnt; over the control on kidney bean, barley, potato and garlic. These results suggest that ALA has plant growth regulating properties at low concentrations and may enhance agricultural productivity.

    Immunohistochemical demonstration of serotonin-containing nerve fibers in the inferior olivary complex of the rat, cat and monkey (1983)

    Notes: Summary By the use of a modified peroxidase-antiperoxidase immunohistochemical method, the distribution of serotonin-containing nerve fibers was studied in the inferior olivary complex of the rat, cat and monkey. The entire inferior olivary complex of all three species contained serotonin fibers, and species-related differences in the distribution of serotonin fibers were observed. In the rat, the overall density of serotonin fibers was sparser than that in the other two species; the highest concentration of varicose serotonergic fibers was noted in the lateral portion of the dorsal accessory olive. In the cat, the densest distribution of serotonin fibers occurred in the caudal portion of the medial accessory olive, the dorsomedial cell column and the lateral portion of the dorsal accessory olive, where intervaricose segments of serotonin-immunoreactive fibers were not so distinct. In the monkey, the caudal medial accessory olive, the lateral portion of the dorsal accessory olive and the dorsal as well as the lateral lamella of the principal olive showed a maximum density of serotonin fibers. Apart from the influence of afferent serotonergic projections to the cerebellum, serotonergic neurons of the brainstem are considered to affect Purkinje cells via neurons of the inferior olivary complex projecting to the cerebellum particularly in the cat and monkey.

    Immunohistochemical demonstration of serotonin-containing nerve fibers in the cerebellum (1982)

    Notes: Summary The localization of serotonin (5-HT)-immunoreactive nerve fibers in the cerebellum of the rat and cat was investigated by means of the peroxidase-anti-peroxidase (PAP) method using highly specific antibodies to 5-HT. Serotonin-containing nerve fibers were distributed throughout the entire cerebellum including the deep cerebellar nuclei, while 5-HT-positive neuronal somata were not detected in the cerebellum of either species. A different pattern of 5-HT innervation was found among the three layers of the cerebellar cortex. There were also interspecific differences in the pattern of distribution of 5-HT. In the rat, the pool of 5-HT nerve fibers mainly consisted of tangential elements, which were predominant in the molecular layer, while in the cat only a few 5-HT fibers were found in the molecular layer of the cerebellar cortex; dense networks of 5-HT nerve fibers were present in the granular layer. Some differences are evident in the pattern of distribution of 5-HT fibers in cerebellar regions classified on an anatomical and functional basis.
