    Notes: Summary The morphology of enterochromaffin (EC) cells in the human fundic mucosa was investigated at the lightmicroscopic level by means of the unlabeled peroxidase anti-peroxidase method, with the use of a highly specific anti-serotonin serum. EC-cells in the human fundic mucosa were sparsely distributed below the neck portion of the gland, but were found to be rather numerous in its lower half. Immunohistochemistry revealed marked pleomorphic and seemingly polynuclear EC-cells or cells with long, sometimes multipolar cytoplasmic processes. In addition, luminal contacts and contiguity between EC-cells, or interglandular connections were also encountered. The present immunohistochemical procedure permits, for the first time, a clear-cut morphological visualization of the entire population of EC-cells, and reveals the distinctive morphological features of these cells in the human fundic mucosa. These morphological findings imply that EC-cells in the fundic mucosa may be crucial in gastric function.

    Notes: Summary In an attempt to identify pancreatic islet cells emitting formaldehyde-induced fluorescence (FIF), the pancreatic islets of the domestic fowl were studied by combined fluorescence, ultrastructural, silver-impregnation and immunohistochemical methods in the same section or in consecutive semi-thin and ultra-thin sections. The results indicate that islet cells emitting intense FIF exhibit a strongly argyrophil reaction with the Grimelius' silver method and also immunohistochemical reaction with anti-glucagon serum, but not with anti-5-HT serum. Therefore, the fowl islet A cell, a peptide hormone-producing cell, stores simultaneously catecholamine as biogenic amine. The islet B and D cells did not display any FIF, any argyrophil reaction with the Grimelius' silver method, or any immunoreactivity with anti-glucagon or anti-5-HT sera. The fluorescent but non-argyrophil cells dispersed in the exocrine acinus may well be PP cells.

    Notes: Summary 5-hydroxytryptamine (5-HT, serotonin)- and opsin-immunoreactive sites were studied in the developing pineal complex of the stickleback, Gasterosteus aculeatus L., by use of light-microscopic indirect immunoperoxidase techniques. 5-HT immunoreactivity first occurs in the pineal organ at the age of 80 h after fertilization and appears to be localized in cells of the photoreceptor type. The outer segments of a few pineal photosensory cells exhibit opsin immunoreactivity at the age of 84 h after fertilization. The number of cells seems to increase until the pineal organ is completely developed. The increase in the number of 5-HT immunoreactive perikarya runs parallel in time to that of the opsinimmunoreactive outer segments. The cells of the parapineal organ show neither opsin nor 5-HT immunoreactivity. The retina of the embryonic stickleback does not display opsin immunoreactivity until after hatching, which takes place about 144 h after fertilization. These results suggest, in the three-spined stickleback, an earlier light-perception capacity for the developing pineal organ than for the retina.

    Notes: Summary The ontogeny of the endocrine cells of the gut of the cockroach Periplaneta americana was studied by immunohistochemistry. During embryogenesis, the midgut begins to be formed as an outgrowth of the foregut and hindgut invaginations. Gut endocrine cells with pancreatic polypeptide (PP)-like immunoreactivity begin to appear at the anterior and posterior ends of the forming midgut. These cells are restricted to the midgut epithelium, and no mitotic cells with PP-like immunoreactivity are observed. These results strongly suggest that the gut endocrine cells, at least those with PP-like immunoreactivity, are derived from precursor cells they have in common with other epithelial cells of the midgut.

    Notes: Summary The anterior pituitary of colchicine-pretreated male and female rats from 20 days to 12 months of age was stained immunohistochemically with anti-rat prolactin serum. Immunoreactive mitotic cells were identified in all groups of rats. In adult female rats the mitotic index of prolactin cells was higher at oestrus than at other stages of the oestrus cycle and than that in male rats of comparable ages. If adult female rats were ovariectomized on the second day of dioestrus or on the day of proestrus, the mitotic indices at presumptive oestrus were less than those in sham-operated controls at oestrus. Estrogen administration to ovariectomized rats significantly elevated the mitotic index of prolactin cells at 48 h after the treatment. The mitotic indices of prolactin cells in female rats reached a peak at 60 days of age, and then decreased with age. In male rats the mitotic indices showed a steady decrease from the value at 20 days of age. A sex difference in the mitotic indices of prolactin cells was noted from 60 days to 12 months of age. The present results clearly demonstrate that differentiated prolactin cells can undergo mitosis and that a sex difference in the mitotic activity of prolactin cells is present during adult life.

    Notes: Summary The distributional pattern of serotonin-containing nerve fibers in the hypothalamus of the monkey (Macaca fuscata) was analyzed with the use of the peroxidaseantiperoxidase method in conjunction with a highly sensitive and specific anti-serotonin serum. The highest concentrations of serotonin-immunoreactive varicose fibers were found in the nucleus praeopticus medialis, nucleus ventromedialis hypothalami, and the complex of mammillary nuclei (nucleus praemamillaris, supramamillaris, mamillaris medialis et lateralis). However, the nucleus suprachiasmaticus, where numerous serotoninergic fibers have been reported to occur in the rat, appeared to be almost devoid of these fibers. The infundibular stalk, and the intermediate and posterior lobes of the pituitary contained considerable numbers of immunoreactive fibers. The present study provides a morphological basis for possible clarification of the influence of serotoninergic projections on various neuroendocrine mechanisms in primates. Furthermore, an attempt was made to clarify the differences and similarities concerning the distributional patterns of serotoninergic nerve fibers within the monkey hypothalamus in contrast to the rat hypothalamus.

    Notes: Summary Adrenal glands of human fetuses were investigated by means of an immunohistochemical method with the use of an anti-S-100 serum. S-100-immunoreactivity was recognized in sustentacular cells located among the chromaffin cells. A characteristic circular arrangement of the immunostained cells was found in the central region of the adrenal glands. It surrounded aggregations of non-argyrophilic, small, round cells, which were identified as the remaining sympathoblasts (primitive sympathetic cells).

    Notes: Summary The catecholamine-synthesizing enzymes, tyrosine hydroxylase, dopamine-β-hydroxylase and phenylethanolamine-N-methyltransferase were examined by immunohistochemistry in hypertrophied paraganglia of aged male Fischer-344 rats. All paraganglionic cells reacted with antibodies against tyrosine hydroxylase. Dopamine β-hydroxylase was identified in most paraganglionic cells, indicating that they synthesized norepinephrine. A variable number of paraganglia were positive for phenylethanolamine-N-methyltransferase, which suggested that they synthesized epinephrine. The formaldehyde-induced fluorescence method demonstrated greenish-yellow fluorescence or yellowish-brown fluorescence. The intensity of the fluorescence was in the same range as in adrenal medullary cells. The observations indicate that paraganglia are capable of synthesizing epinephrine.

    Notes: Summary Eleven monoclonal antibodies that recognize membrane determinants on spermatozoa of the carp Cyprinus carpio L. have been produced. Indirect immunofluorescence revealed that these determinants are uniformly distributed on the surface of head and midpiece. Most of them are also present on the outer membrane of precursor sperm cells. Although none of the monoclonal antibodies reacted with carp somatic tissue, five monoclonal antibodies were positive for surface membrane determinants of oogonia and early prophase oocytes in carp ovary. Preliminary analysis of the testis and ovary of three other species of fish showed that some carp determinants are shared with germ cells from Barbus conchonius, Clarias lazera, or Salmo gairdneri.

    Notes: Summary Two antigens of the β-glycoprotein fraction from rabbit uterine secretion of the seventh day post coitum were purified firstly by gel filtration on Sephadex G 150, then either by ion exchange chromatography on DEAE Sephacel or chromatofocusing on PBE 94. By the use of a specific antiserum, raised in female sheep, two antigens with α 2- and β 2-mobility in agar gel electrophoresis could be demonstrated. Immunohistochemical staining of the uterine epithelium at the seventh and eighth day post coitum showed the antigens to be localized in a ciliated cell type of conspicuous shape, which is supposed to be the site of synthesis. Stain accumulated mainly in the apical part of the cell, but there were also small deposits around the nucleus.

    Notes: Summary A peptide hormone was extracted from the porcine right atrium following a bioassay for differential vaso-relaxant effects on smooth muscle strips from aorta and renal and inferior mesenteric arteries. The isolation procedure included several steps of gel-permeation and ion-exchange chromatography, and high performance liquid chromatography. During the isolation procedure, other peptides of smaller molecular weight were also found, which, in relation to cardiodilatin-126 (CDD-126), are shorter at their N-terminal. Among these, CDD-88 has also been isolated and characterizied, and has been established as a prominent member of the cardiac hormone family. The N-terminal and C-terminal segments of the 126 amino acid-containing molecule were synthesized and used to raise region-specific antibodies. The natural peptide was then localized within myoendocrine cells of the right atrium where specific atrial granules are located. Renal effects of cardiodilation were studied in conscious dogs and showed strong diuretic and natriuretic activities. According to our functional studies, cardiodilatin-126 and cardiodilatin-88 possess qualities of a significant hormone family regarding the regulation of extracellular fluid volume and blood pressure.
