Biogenic monoamines in the central nervous system of molluskTritonia sp.

Neuroscience and Behavioral Physiology, 1972
The localization of biogenic monoamines in the CNS of the Pacific nudibranch molluskTritonia sp. was investigated by the method of Falck and Hillarp. Neurons with specific yellow luminescence, evidently due to serotonin, were found in the cerebral, pedal and gastro-esophageal ganglia.

Fluorescence Histochemistry of Biogenic Monoamines

1981
Several aldehydes are capable of converting biogenic amines to intensely fluorescent derivates: fluorophores. This reaction, under defined conditions, can be used as a highly sensitive and specific method for the histochemical demonstration of biogenic monoamines at the cellular level.

On the selective inhibition by some monoamine oxidase inhibitors of deamination of biogenic monoamines in vivo

Biochemical Pharmacology, 1968
Abstract Pargyline previously shown to be in vitro a selective inhibitor of deamination of tyramine by rat liver mitochondrial MAO causes in vivo a distinct selective inhibition of tyramine deamination in liver, kidney, and brain tissues of rat. No correlation could be found between the results of similar in vitro and in vivo experiments with

Monoamine oxidase A deficiency: Biogenic amine metabolites in random urine samples

1998
We have recently described an association between abnormal behaviour and monoamine oxidase A (MAO-A) deficiency in several males from a single large Dutch kindred. A characteristically abnormal excretion pattern of biogenic amine metabolites was present in 24-hour urine of affected males.

The Distribution of Biogenic Monoamines in Invertebrates

1985
This Chapter presents a short overview about our knowledge of the presence and localization of biogenic monoamines (bMA) in invertebrates. Biogenic MA are known as neuroactive substances and their occurence in the nervous system will be of main concern in this article. Their distribution was studied in several invertebrate phyla by numerous authors and

[Effect of 7-hydroxygluacine on brain biogenic monoamines].

Farmakologiia i toksikologiia, 1985
In experiments on male albino rats it was established that the aporphine alkaloid 7-hydroxyglaucine injected i.p. at a dose of 1/10 of the LD50 induced many changes in the brain level of biogenic amines. Serotonin content was significantly increased in all brain structures studied (whole brain.

Biogenic Monoamines and Amino Acids as Retinal Neurotransmitters

1978
Dopamine was not the first substance presumed to be a neurotransmitter in the retina, but today it is probably the best proven. The first indication of this role was obtained in 1963. With the aid of the formaldehyde histofluorescence method of FALCK and HILLARP it was shown that the formaldehyde treatment induced fluorescence in certain neurons of the
