    Notes: Summary One of two cases of acquired immune deficiency syndrome-related persistent generalized lymphadenopathy revealed a profoundly altered pattern of dendritic reticulum cells as demonstrated by immunoreactive acid cysteine proteinase inhibitor. The alterations could be related to totally or partially destructed lymphoid secondary follicles.

    Notes: Summary The distribution of A(M) subunits of lactate dehydrogenase (mainly LDH5) in developing muscle, heart, liver, lung, kidney and cartilage tissue of chicken embryos was examined by the indirect fluorescent antibody technique. Antibodies against porcine LDH5, purified by affinity chromatography, were used for this purpose. In special areas of newly formed myofibrils in somitic myoblasts fluorescence was already detected after 4 days of incubation, and located at the same place in muscle tissue of all advanced developmental stages examined. During the myotube stage of muscle development staining was also located in the peripheral thickened cytoplasma of the myotubes. The myocardium did not exhibit any fluorescent staining in the developmental stages examined. Endocardium, epicardium and pericardium, however, were fluorescent in young developmental stages. The liver showed fluorescence in 5- to 8-day embryos mainly in the endothelial cells of the blood sinusoids. In 9- to 12-day embryos the bile ducts became fluorescent. In lungs after 9- to 12-day development the epithelium and the surrounding tissues of bronchi exhibited strong immunofluorescence. The mesonephros exhibited faint granular fluorescence in tubule-forming cells and their membranes after 4–9 days of incubation. Advanced developmental stages only exhibited fluorescent blood cells. This latter staining is at least partly due to non-specific reactions of blood cell membranes with FITC-conjugated anti-rabbit IgG. Cartilage is characterized by non-specific fluorescence, but in embryos older than 8 days strong granular fluorescence of chondrocytes and staining of the perichondrium distinguished sections treated with anti-LDH5 antibodies from control sections reacted only with FITC-conjugated anti-rabbit IgG. In addition, strong fluorescent staining was detectable in certain areas of the 5-day neural tube and faint staining in the mucosa of the intestine from embryos older than 10 days.

    Notes: Summary Immunohistochemistry and fluorescence histochemistry were applied to the skin of the frog, Bombina orientalis, to detect the localization of bombesin and 5-hydroxytryptamine. The dermal layer contains three types (type 1, 2 and 3) of cutaneous glands but only the type-1 gland simultaneously contains bombesin and 5-hydroxytryptamine. This result suggests for the first time the coexistence of a bioactive peptide and monoamine in a cutaneous gland of the frog.

    Notes: Summary Immunohistochemical localization of corticotropin-releasing factor (CRF)-like immunoreactivity in the brain of the Japanese quail was studied by means of the peroxidase anti-peroxidase (PAP) method. CRF-immunopositive perikarya of parvocellular neurons were observed mainly in the nucleus praeopticus medialis and nucleus paraventricularis. Additional perikarya were also detected in the nucleus hypothalamicus posterior medialis in the hypothalamus and in the non-hypothalamic nucleus accumbens, nucleus septalis lateralis and nucleus dorsomedialis and dorsolateralis thalami. No CRF immunoreaction was found to coexist with the vasotocin (Vt)-containing system in comparative examination of consecutive sections treated with anti-vasopressin (Vp) serum. The CRF-immunoreactive fibers were detected mainly in the external layer of the anterior median eminence but not in its posterior division. Unilateral adrenalectomy induced the marked reduction in number of the CRF immunopositive fibers in the anterior median eminence.

    Notes: Summary Ontogenesis of gastrin cells was studied in the pyloroduodenal mucosa of the mouse using anti-human G17 serum, R-1301, and anti-human G34(1–15) serum, R-2703. R-1301-immunostained cells first appeared in the pyloric mucosa of 14-day-old fetuses. Cells stained with both R-1301 and R-2703 appeared immediately after birth, and gradually increased in number to the adult level. Most R-1301-reactive cells were also reactive to R-2703, whereas some cells that reacted with R-1301 exhibited very weak or no reaction with R-2703. The discrepancy between these two immunoreactivities is discussed. In the duodenum, a considerable number of R-1301-reactive cells were present from the perinatal stage and through out adult development. A few R-2703-reactive cells were seen in the duodenum of young mice but not of the adult.

    Notes: Summary Neurones in the suboesophageal ganglion of the locust Schistocerca gregaria were stained with an antiserum raised against gamma amino butyric acid (GABA). This ganglion consists of the fused mandibular, maxillary and labial neuromeres. Immunoreactive cell bodies of similar size and distribution occur in the lateral, ventral and middorsal regions of all three neuromeres. Approximately 200 cell bodies stain in both the mandibular and maxillary neuromeres and 270 in the labial neuromere. A few distinctly larger cells occur in the ventral groups and one large pair occurs in the lateral group of the maxillary neuromere. Dorsal commissures DCIV and DCV are composed mainly of stained fibres, while DCI–DCIII are largely unstained. A ventral commissure also stains in the maxillary neuromere. All longitudinal tracts contain both stained and unstained fibres. Many processes within the neuropil are also immunoreactive. A stained axon is found in the posterior tritocerebral commissure which enters the anterior dorsal region of the mandibular neuromere. The salivary branch of the 7th nerve contains one stained axon and two axons stain in nerve 8 which innervates neck muscles.

    Notes: Summary A study on the localization of fetal and neonatal brain macrophages of mice from embryonic day 10 (E10) to postnatal day 21 (P21) was carried out immunohistochemically using a monoclonal antibody against a macrophage differentiation antigen (Mac-1) and the labeled avidin-biotin technique. In the central nervous system, the macrophages recognized first were mainly located in the choroid plexuses of the fourth and lateral ventricles at E14. Their number increased at E17–P3 and gradually decreased thereafter. In the cerebral parenchyma, a few macrophages appeared at E14 in the matrix cell layer. They were also detected in the migrating zone at E15, E17 and in the cortical plate at E19. Mapping of positive cells at the stage of neuroblast formation (E15, E17, E19) disclosed the precise distribution of cerebral macrophages. The macrophages that appeared first in the choroid plexuses at E15 may be derived from the subarachnoid vessels, which extend into the stroma of the choroid plexuses when the matrix cell layer invaginates into the lateral ventricle to form the choroid plexuses. Almost all of the macrophages recognized in the cerebral parenchyma disappeared at P9 when the cytoarchitecture seemed to be completed. In the cerebellum, which develops later than the cerebrum, macrophages appeared after birth and were located mainly in the internal granular layer. The brain macrophages always appeared in the regions where cell proliferation and brain remodeling are most active at each stage. These findings suggest that fetal and neonatal brain macrophages may play an important role in scavenging degenerated cells and cell debris during histogenesis of the central nervous system.

    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary The innervation of the ductuli efferentes and seven zones of the guinea-pig epididymis was investigated using immunohistochemical, histochemical and electron-micro-scopical techniques. Nerve fibers were localized by use of antibodies against substance P (SP-IR), vasoactive intestinal polypeptide (VIP-IR) and dopamine-beta-hydroxylase (DBH-IR). In the ductuli efferentes and all zones of the epididymal duct, SP-IR is consistently observed in the interstitial tissue and perivascular areas. Histochemistry reveals a significant amount of acetylcholinesterase-containing fibers in the interstitial, perivascular and periductal smooth muscles of the ductuli efferentes and zones V, VI and VII. In contrast to the homogeneous distribution of SP-IR within all zones of the epididymis, VIP-IR is seen only in zones VI and VII. Within these zones, VIP-IR is detected in large amounts in the subepithelial and muscular layers as is a sparse number of SP-IR varicosities. DBH-IR is also seen throughout all zones in the interstitial and perivascular regions with a tendency to increase in zones VI and VII. Transmission electron microscopy (TEM) reveals evidence of a cholinergic (agranular vesicles, AGV), adrenergic (small granular vesicles, SGV) and peptidergic (large granular vesicles, LGV) innervation throughout the interstitial connective tissue of the ductuli efferentes and all epididymal zones. Furthermore AGV are localized in the subepithelial layer, and also co-stored with LGV in the muscular layer of zones VI and VII. No nerve profiles were encountered within the epithelium. Correlation of immunohistochemical findings to TEM counterparts as well as their possible functional role are discussed.

    Notes: Summary The cellular localization of renin was examined in the kidneys of some amphibians of the genus Bufo by immunoperoxidase and immunofluorescence techniques with an antiserum to renin isolated from the submandibular gland of the mouse. Immunoreactivity could be demonstrated in the media cells of the afferent arterioles (juxtaglomerular cells) close to as well as at great distance from the glomeruli. Occasionally, media cells of larger arterial vessels were also stained. The immunohistochemical data seem to be in accordance with earlier results obtained with a modified silver impregnation technique (Movat's staining procedure) used for the visualization of juxtaglomerular cells in non-mammalian vertebrates. Mouse kidney tissue, studied for purposes of comparison, showed renin-immunoreactivity as described by earlier investigators, i.e., immunoreactive staining in the afferent arterioles near the glomeruli and in the proximal tubule cells.

    Notes: Summary The distribution of endocrine cells in the gastrointestinal tract of the house musk shrew, Suncus murinus (Family Soricidae, Order Insectivora) was studied immunohistochemically. The hormones investigated were gastrin, cholecystokinin (CCK), somatostatin, secretin, glucagon, gastric inhibitory polypeptide (GIP), motilin and neurotensin. In the gastric mucosa, gastrin and somatostatin cells were only found in the pyloric regions, and no other hormonal cell-types were observed. In the intestinal mucosa, the largest number of endocrine cells belonged to the gastrin and glucagon/glicentin cell-types, whereas CCK-33/39 and secretin cells were the least numerous. Numbers of other cell-types were intermediate between these two groups. The gastrin and GIP cells were mostly localized in the proximal portion of the intestine, decreasing in number towards the distal portion. The motilin and CCK-33/39 cells were restricted to the proximal half. The glucagon/glicentin and neurotensin cells were most abundant in the middle portion. The somatostatin and secretin cells, although only present in small numbers, were randomly distributed throughout the intestine. This characteristic distribution of gastrointestinal endocrine cells is discussed in comparison with the distribution patterns of other mammals.
