    The endocrine nature of the paraganglia of man (1978)

    Notes: Summary Brightly fluorescent paraganglia were found in the retroperitoneal tissue of adult man. The histofluorescence properties of the paraganglia indicate the presence of tryptophyl peptides, which might be of endocrine importance.

    Paraganglia in the urogenital tract of man (1976)

    Notes: Summary According to the earlier concept, the paraganglia of man are believed to degenerate during the first postnatal years after their dominance during the fetal period. Clinical case reports on persisting paraganglia led us to extensive exploration of surgical material obtained from urological and gynecological surgery. The formaldehyde induced fluorescence (FIF) was used for tracing the catecholamine containing tissues. The fluorescence intensities were recorded with a Lietz MPV 2 microspectrophotometer. Solitary, small paraganglia were found in all patients studied. They were expecially frequent in the walls of the urinary bladder and in the connective tissue surrounding the urogenital organs. The intensity of the fluorescence was comparable to pharmacological standard of 10−2 M noradrenaline and at the same level as the FIF of human fetal paraganglia. All cells of the paraganglionic clusters exhibited FIF and no signs of degeneration could be observed. It is suggested that the paraganglia of man do not degenerate postnatally but persist as a remarcable catecholamine reservoir, which might be of physiological importance.

    Vacuolated neurons in the hypogastric ganglion of the rat (1979)

    Notes: Summary The vacuolated neurons (VN) of the main hypogastric ganglion of the male rat were studied using the formaldehyde-induced fluorescence (FIF) method for the histochemical demonstration of catecholamines. Microspectrofluorimetry was performed to identify the fluorophores and to quantify the FIF. The thiocholine method (Koelle-Gomori) was used to demonstrate acetylcholinesterase activity. The fine structure of the VN was studied using glutaraldehyde/OsO4 fixation. (1) In the untreated adult male rat VN represent only a small population of the total number of hypogastric neurons (0.8–1.2%). The vacuoles are similar to those of the VN from the corresponding female ganglion. (2) The VN are considered to be adrenergic due to the nature of their fluorophore, indicating a primary catecholamine. (3) The first VN appear in the hypogastric ganglia at the age of 7 weeks. After testosterone administration to young rats, VN are found at the age of 4 weeks. (4) The basic fine structure of the VN is similar to that of other ordinary neurons of the hypogastric ganglia. (5) The content of the vacuoles could not be identified. (6) Indications of degeneration were not observed in the VN. (7) The VN are interpreted as being a functional stage of the “short” adrenergic neurons, which are under the control of steroid hormones. (8) Fifteen months after castration, no VN could be found in the hypogastric ganglia, while their number was normal in the corresponding control animals.

    Innervation of the ventral prostate of the rat (1979)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The autonomic innervation of the rat ventral prostate was studied in an attempt to evaluate the role of innervation in the normal function of the gland. Specific histochemical methods for both catecholamines (the formaldehyde-induced fluorescence method, FIF) and acetylcholinesterases (the Gomori-Koelle thiocholine method) were used. The neuro-effector contacts were studied by electron microscopy using both 3% glutaraldehyde and 3% potassium permanganate (KMnO4) as fixatives. It was found that the rat ventral prostate receives dual autonomic innervation. Adrenergic fibers, which formed the majority of the nerves, were often seen in close contact with the smooth muscle cells around both the prostatic alveoli and secretory ducts. The non-adrenergic nerve fibers, which were fewer in number, did not form such intimate contacts with the muscle cells. No direct synapses with epithelial cells were detected.
