    Notes: Summary The peptidergic innervation of the temporomandibular disk was investigated in the postnatal young rat by using an indirect immunofluorescence method. Calcitonin gene-related peptide-containing nerve fibers were located around the blood vessels and terminated as free nerve endings in the disk. These nerve fibers may be of a sensory nature.

    Histochemical, ultrastructural and X-ray microprobe analytical studies of localization of calcium in the mucous lining of the rat duodenum (1988)

    Notes: Summary Localization of calcium in a rapid frozen and freeze substituted duodenum of normal, starved or calciumrepleted rat was examined using either of the glyoxal bis(2-hydroxyanil) (GBHA) staining method, a sensitive histochemical calcium stain or electron microscopy. In normallyfed rats, a majority of absorptive cells of the duodenum showed numerous discrete red granular GBHA reactions, approximately 1 μm or less in diameter, located primarily along their lateral plasma membranes and within intercellular spaces. Electron microscopy also revealed electron-dense granules, 30–100 nm in diameter, showing a similar distribution as the GBHA granules in the respective absorptive cells, and confirmed their absence in mitochondria and other intracellular compartments. Some of the absorptive cells located exclusively at the tip of each villus contained highly GBHA-reactive tubulo-vesicular structures extending throughout the cytoplasm. However, they displayed virtually no granular GBHA reaction. In these cells, electron microscopy revealed numerous electron-dense granules in the nucleus, mitochondria and in other unidentified organelles. X-ray microprobe analyses of ultrathin sections confirmed the presence of calcium within electron-dense granules associated with both types of absorptive cells. The number and intensity of all GBHA reactions fluctuated according to luminal calcium concentration. In calcium-repleted rats, strong GBHA reactions appeared in a narrow zone of lamina propria at the tip of the villus, overlaid, predominantly, with absorptive cells showing tubulo-vesicular GBHA reactions. these results suggest the existence of distinct types of absorptive epithelial cells in the rat duodenum, with respect to patterns of calcium localization which they display.

    The distribution and origin of calcitonin gene-related peptide-containing nerve fibres in feline dental pulp (1987)

    Notes: Summary The origin and distribution of calcitonin gene-related peptide (CGRP)-like immunoreactivity in feline dental pulp were studied using indirect immunofluorescence. Nerve fibres with varicosities exhibiting CGRP-like immunoreactivity were observed to enter the pulp with blood vessels. Many CGRP-containing nerve fibres were found to extend along blood vessels in the central pulp, and some of these fibres exhibited a network arrangement in the walls of dental pulp blood vessels. However, some of fibres were apparently not associated with blood vessels. Some thin, CGRP-containing nerve fibres formed a part of the nerve plexus in the subodontoblastic area and penetrated into the odontoblastic layer. In animals that had undergone transection of the inferior alveolar nerve, no CGRP-containing nerve fibres were observed. Application of a double-immunofluorescence staining technique also revealed that the distribution of CGRP-containing nerve fibres is very similar to that of substance P-containing nerve fibres.

    Effect of direct current stimulation on triradiate physeal cartilage (1993)

    Notes: Summary Electrical stimulation with 8 μA direct current was applied to the triradiate physeal cartilage of young rabbits for periods of 3, 4, and 5 weeks. The effect was evaluated by morphometric measurement and histological observation. We tried to improve some previously described technical problems (e.g., movement of electrode during experiment) in this model of the growing acetabulum. Statistically significant differences in acetabular depth were found between the experimental and the control side in the 3-week group, but no obvious differences were found among the other measurements. Characteristic thickening of the growing physeal cartilage, especially proliferating cells, was found in the stimulated sides. Electricity affects the cell behavior in the triradiate physeal cartilage as well as the growth plate of long bone, but further study is still necessary to find more appropriate conditions to gain actual growth.

    Notes: Abstract Bone change induced by knee immobilization was assessed on dissected femurs and tibias to clarify the influences upon the mechanical properties and their demands. Fifty-eight Wistar-Imamichi male rats (11–12 weeks old, body weight 350–450 g) were subjected to knee joint immobilization (150° flexed position) on one side while the opposite side served as a control. Animals were killed in seven groups at time intervals of 1, 2, 3, 4, 5, 7, and 10 weeks. The hind leg was extirpated and prepared for (1) biomechanical analysis by the indentation method at the articular surfaces of the femoral condyle and head and at the subchondral bone of the proximal tibia, and for (2) dual-energy X-ray absorptiometry of the distal metaphysis of the femur. The biomechanical parameters measured induced dynamic stiffness and phase lag derived from forced oscillation (preload 3 N, cyclic load 2 N and 11 Hz, 35 Hz), and bone mineral density was analyzed. These were compared between the immobilized side and control side, and among the seven time groups. The biomechanical results showed an early change of osteocartilaginous properties at the femoral condyle, a late response at the tibial subchondral bone, and no change at the femoral head. The measurement of bone mineral density revealed that a very sensitive reaction started within 1–2 weeks. This study provides objective data demonstrating that disuse or lack of mechanical stress greatly affects the remodeling activity for homeostasis of joints, and dramatically impairs normal bone mineral density next to the immobilized joint in young animals.

    Notes: Summary Electrical stimulation of 8 μA direct current was applied to the femoral distal growth plate of young rabbits for periods of 1, 2, and 3 weeks to examine the effect on bone growth. The results were analyzed using X-ray measurement, histological observation including tetracycline labeling, and glycosaminoglycans analysis. No obvious differences between the stimulated side and the control side were observed in the morphological and biochemical studies, but characteristic thickening of the growth plate caused by the accumulation of hypertrophic cells was found in the group stimulated for 2 weeks. Electricity affects the cell behavior of the growth plate, but it is necessary to find more appropriate conditions to stimulate obvious bone growth.

    Influence of colchicine on the addition of a sugar to the enamel protein in secretory ameloblasts of cultured germs of rat molar tooth by 3H-galactose radioautography (1990)

    Notes: Summary The influence of colchicine on the addition of 3H-galactose to the enamel protein in secretory amelloblasts of cultured germs of rat molar tooth was investigated by light- and electron-microscopic radioautography. In tooth germs cultured without colchicine, the reaction products of 3H-galactose were observed over Golgi cisternae at early chase times and then localized over the enamel with time. In tooth germs cultured with colchicine, the silver grains were seen over the Golgi cisternae, condensing granules and accumulated secretory granules. Some grains also appeared with time over the pale granular material precipitated in the intercellular space with colchicine treatment. In quantitative analysis with light microscopic radioautography, values of silver grain counts over the unit area (100 μm2) on ameloblasts and enamel of colchicine-treated tooth germs were significantly lower at both 0 min and 30 min chase after 30 min pulse than those of control tooth germs, respectively. This finding indicates that colchicine diminished the incorporation of 3H-galactose into the secretory ameloblast of cultured tooth germs. It is suggested that colchicine decreases the activity of the Golgi apparatus with regared to the addition of sugar to the synthesizing glycoprotein in the secretory ameloblast.
