    Granulocytic Colony Stimulating Activity in Plasma and Leukocytes from Chronic Myelogenous Leukemia Patients
    (1976-11) Patchen, Myra L.; Graham, James D.
    Colony stimulating activity present in plasma and in leukocytes from chronic myelogenous leukemia patients and from normal volunteers was determined by double layer bone-marrow tissue culture. Plasma and leukocytes incorporated into the bottom feeder layer stimulated the formation of colonies from human bone-marrow cells cultured in the upper semi-solid agar layer. The colony stimulating activity of plasma from chronic myelogenous leukemia patients was significantly increased over that of normal plasma (p<.01). The difference between the colony stimulating activity of chonic myelogenous leukemia and normal leukocytes was not statistically significant. After 14 days of incubation, all bone-marrow cell colonies were composed primarily of macrophages rather than granulocytes as had been previously reported.

    Photoperiodic Effects on the Postjuvenal Molt of the Eastern Bluebird
    (1976-11) Pinkowski, Benedict C.
    The postjuvenal (first prebasic) molt and its relationship to nesting and migration was studied in Eastern Bluebirds (Sialia sialis) in southeastern Michigan during 1972 to 1975. Experimental data were accumulated on birds observed in captivity to assess the effect of photoperiod on variability in the molt. Juveniles reared in spring molted between 18 July and 10 September and those reared in summer molted between 26 August and 16 October. Individual birds reared late in the season molted more rapidly and began the molt when younger after a shorter post-fledging period than birds hatched early in the season. Only juveniles hatched late in summer did not complete the molt before leaving the breeding grounds. Observations on captive birds indicated that the more rapid molt of late hatchlings was attributable to photoperiod at the beginning of the molt interacting with the age of the bird. Although some juveniles molted the rectrices and others did not, daylength at the onset of the molt was significantly shorter for captive birds that did not renew the rectrices than for those molting the rectrices (P<0.01). Modifications of the molt by late hatchlings, especially elimination of the rectrix molt, may represent bioenergetic adjustments to the reduction in time between hatching and the winter season.

    Sex Differences in the Tendency for Brown-Headed Cowbirds and Red-Winged Blackbirds to Re-Enter a Decoy Trap
    (1976-11) Burtt, Harold E.; Giltz, Maurice L.
    Female Red-winged Blackbirds and Brown-headed Cowbirds re-entered a decoy trap with greater frequency than did the males. It appeared that this difference in behavior was due to the location of the trap in the breeding territories of these two species. Although the Brown-headed Cowbird is a nest parasite, it does exhibit many of the same breeding territorial relationships between the sexes as the Red-winged Blackbird, which is polygynous. The female Red-winged Blackbird does all of the nest building, incubation of the young, care of the nestlings, and most of the fledging of the immatures while the males desert their breeding territories for a time each day. This behavior alone would explain females' greater re-entry in the trap. The trap, with its decoys, is a social stimulant and the female may be more susceptible to such a stimulus.

    Psychological Characteristics of the Epileptic
    (1976-11) Hoover, Thomas O.; Wagner, Edwin E.
    Forty noninstitutionalized epileptics were matched with 40 physically handicapped Ss individuals. A representative battery of psychological tests was administered to both groups. The epileptics and handicapped subjects were compared on 42 variables by batteries of psychological tests, 14 of which proved significant. When the significant predictors were intercorrelated and a Wherry-Doolittle multiple R derived, 3 variables were found to contribute unique variance the (WAIS) Weehslor Adult Intelligence Scale and full scale IQ, Rorschach 2c, and Hand Test CRIP. Results were interpreted as indicating that epileptics tend to resemble patients with organic brain syndromes and appear to be lacking in behavioral control and sensitivity to their condition.

    Distribution and Species of 17-Year Cicadas in Broods V and VIII in Ohio
    (1976-11) Forsythe, H. Y., Jr.
    The distributions of Broods V and VIII of 17-year cicadas, Magicicada spp., were surveyed in Ohio by collecting adults, recording male songs, mapping ovipositional flagging records, and using questionnaires. Brood limits in 1965 and 1968 showed signs of receding, primarily away from some large urban centers. Cicada populations of each brood were large and more widespread in southern Ohio. Populations were generally smaller and more isolated in northern counties. M. septendecim (L.) was found in 41 (probably 43) counties in 1965 and in six counties in 1968. M. cassini (Fisher) and M. septendecula Alexander and Moore were recorded from 34 and 23 counties, respectively, in 1965 (Brood V), but not from the northernmost counties. M. septendecula was not found in Ohio in 1968 (Brood VIII); M. cassini was collected from three counties.

    Trypanosoma Cruzi: Observations on Entry, Development, Release and Ultrastructure of Parasites Grown in Cell Cultures
    (1976-11) Kreier, Julius P.; Al-Abbassy, S. M.; Seed, Thomas M.; Repka, D.
    T. cruzi epimastigotes penetrated cells in culture by a process which involved entanglement of the parasite's flagellum with cellular filopodia. Development of trypomastigotes from intracellular amastigotes appeared to involve a transformation through an epimastigote-like form. Release of trypomastigotes was usually by cell rupture but occasionally trypomastigotes in vacuoles were released from cells without cell rupture. The parasites were examined with the scanning and transmission electron microscopes and three-dimensional views of the organisms were obtained by the scanning and carbon replica techniques. The texture of the outer surface of the limiting membrane of the scanned trypomastigote appeared fairly smooth to granular. Granulations were more evident in the carbon-replicated parasites than in scanned ones. Many amastigotes produced in cell cultures have short flagella. Freeze-cleaved trypomastigotes showed the two lamellae of the unit membrane and a surface coat. The morphology of the outer face of the surface coat and of each face of the lamellae of the unit membrane appeared smooth whereas the inner faces of the cytoplasmic membranes and the flagellar unit membrane were granular. The granules of the former, however, were morphologically distinct from those of the latter. A common outer layer or surface coat, which enveloped both the parasite's body and its flagellum, was evident. When this layer was cleaved away, the flagellar pocket was exposed. The common layer appeared to bind the flagellum to the parasite's body.
