    Mechanics of the syrinx in Gallus gallus. II. Electromyographic studies of Ad Libitum vocalizations (1977)

    Notes: Records of electrical activity in the tracheal muscles of domestic chickens were obtained for a variety of ad libitum vocalizations. Primary attention was given to an analysis of events during the most complex call, crowing.Three pairs of muscles, Mm. tracheohyoideus, tracheolateralis, and sternotrachealis, can affect the configuration of a chicken's syrinx. The firing patterns of the three muscle pairs are related to their different abilities to affect the tension of the syringeal membranes. The influence of M. tracheohyoideus is most indirect and imprecise, and its role the least clearly defined. It appears to adjust the position of the trachea so that the syrinx is isolated from unpredictable and/or undesirable consequences of nuchal position and tracheal elasticity, and also helps draw the glottis caudad, thereby deepening the pharyngeal chamber. The other two muscles interact to control the tension of the vocal membranes. M. sternotrachealis relaxes the membranes by drawing the drum of the trachea caudad, or, via the syringeal ligament, by rotating the pessulus cranioventrad, or both. M. tracheolateralis tenses the membranes and/or prevents caudal movement of the origin of M. sternotrachealis, a necessity if the syringeal ligament is to rotate the pessulus.Vocalization depends on both syringeal configuration and appropriate air flow. Hence, tracheal muscles, syrinx, air sacs, and ventilatory muscles cooperate to form a vocal system. Cooperation elicits a surprising degree of redundancy. At least one call, a high pitched wail, may be produced by two very different techniques.

    The development of neuromasts in Cirrhina mrigala Ham. Buch. (Cyprinidae) and Ophicephalus (Channa) punctatus Bloch (Channidae) (1967)

    Notes: The development of neuromasts was studied in two species of teleosts, Cirrhina mrigala Ham. Buch. and Ophicephalus punctatus Bloch, and the findings are presented and discussed. It has been discovered, in the course of this investigation, that a neuromast arises by a process of invagination  -  a fact hitherto not reported. The occurrence of the dorsal lateral line and the accessory lateral line of the trunk, in addition to the main lateral line, has also been reported for the first time for teleosts, although known for other bony fishes.

    Salivary gland development in the blowfly, Calliphora erythrocephala (1976)
    New York, NY : Wiley-Blackwell

    Notes: The salivary gland of adult Calliphora erythrocephala is a tubular structure composed of secretory, reabsorptive, and duct regions. Development of these structures has been followed during the six days of larval and ten days of pupal growth. Two small groups of imaginal cells located at the junction between larval gland and duct give rise to the adult gland. These presumptive adult cells divide during all larval stages and appear to be functional components of the larval gland. Shortly after pupation, the larval gland breaks down and the imaginal cells proliferate rapidly, forming sequentially the duct, reabsorptive and secretory regions. Proliferating regions of the developing gland are frequently encrusted with haemocytes. As it elongates the gland establishes intimate contacts first with the basement membrane of the degenerating larval gland, later with an epithelial layer surrounding the main dorsal tracheal trunks, and then with the gut. Cell division continues until about five days after pupation, bu t the gland is unable to secrete fluid in response to 5-hydroxytryptamine stimulation until two hours after the adult fly emerges. The Golgi complex appears to be involved in forming the highly folded membranes of the canaliculi in the secretory region.Presumptive adult salivary gland cells appear to increase in number logarithmically from the time of hatching of the larva until five days after pupation. This contrasts with the development of classical imaginal discs, in which cell division ceases prior to pupation.

    The release of amino acids from nerve during stimulationSupported by grant NB03971-03 from the USPHS. (1966)

    Notes: Frog sciatic nerves were incubated for 24 hours in either glycine, aspartic acid, glutamic acid, lysine, leucine, γ-aminobutyric acid, glutamine, or pentanedioic acid (all labeled with C14), and the rates of release of these compounds were monitored under resting conditions and during stimulation. Upon stimulation, the rate or release of glutamic acid increased an average of 200% above the resting rate. This extra release is highly specific with regard to molecular size and structure, since of the compounds tested only glutamic acid gave significant increases in rates of release during stimulation. Ouabain (0.1 mM) had no effect on the rate of release; however, sodium azide (0.2 mM or 1.0 mM) completely eliminated the extra release during excitation, indicating that the increased permeability to glutamic acid is energy-dependent. Competition experiments show that the extra release of glutamic acid can be eliminated with 10 mM concentrations of non-isotopic choline. The hypothesis is advanced that glutamic acid is actively extruded by a highly specific carrier mechanism.

    Centrifugal elutriation: Separation of spermatogenic cells on the basis of sedimentation velocity (1975)

    Notes: Various types of cells from the testes of mice and hamsters were separated according to differences in sedimentation velocity by centrifugal elutriation, a counterflow centrifugation technique. Approximately 3 × 108 cells, prepared from six mouse testes or from one hamster testis, were separated into 11 fractions in less than two hours as compared to the 4-5 hours required for sedimentation at unit gravity (“Staput”). Fractions enriched in elongated spermatids and spermatozoa (100%), stages 1-8 spermatids (69%) and pachytene spermatocytes (58%) were obtained from mouse testis dispersions. Similarly enriched fractions were obtained from hamster cells. A single fraction enriched in stages 1-8 spermatids (mouse) was prepared in less than 30 minutes. As many as 2 × 109 cells were separated in a single procedure. Spermatogenic cells exhibited no evidence of structural damage with trypan blue and phase microscopy, and recovery was essentially 100%. Centrifugal elutriation had no effect on sperm motility or on the plating efficiency of CHO cells.

    The effect of tobacco smoke on the metabolism and function of rat alveolar macrophagesPresented in part at the 1976 meeting of the American Society for Clinical Investigation (1978)

    Notes: Alveolar macrophages harvested by bronchopulmonary lavage from rats exposed to tobacco smoke for 30 days (“smokers”) showed alterations in oxidative metabolism, lactate production and phagocytosis of inert starch particles when compared with control macrophages. Phagocytosis of viable Staphylococcus aureus was unaffected by tobacco smoke. Glucose oxidation measured by conversion of glucose-1-14C to 14CO2 was moderately affected while oxidation of glucose-6-14C to 14CO2 was not. Smokers routinely yielded fewer cells than controls, though these cells contained approximately 17% more protein than did controls. Opsonization of particles was not necessary for macrophages from either smoker or control animals to manifest a respiratory burst and increased superoxide and hydrogen peroxide release during phagocytosis. The glycolytic inhibitors, sodium fluoride and iodoacetamide, while effectively blocking glycolysis, did not inhibit phagocytosis by macrophages from either group. The results reported clearly distinguish alveolar macrophages from other phagocytic cells (peritoneal macrophages and polymorphonuclear leukocytes) and suggest a state of non-specific activation caused by exposure to tobacco smoke.
