    Notes: We provided a water-cornea interface to correct the usual aerial myopia encountered in fundus photography of marine mammal eyes. The 12 Tursiops eyes were consistent for vascular structure, optic papillae, dimensional components and tapetal coloration. Multiple photographs were assembled to produce one ocular fundus typical of Tursiops truncatus and one for Grampus griseus. The eyes have a vestigial hyaloid vessel and an optic disc („blind spot”) that occupies the center of the fundus. The disc is bounded in both species by a vascular structure that is continuous with a (retrobulbar) perineural organ called the ophthalmic rete. The vascular trees of the fundus do not suggest an area of specialization for high resolution. Both species exhibit total tapetalization. Tapetal spectral reflectance did not vary between Tursiops. There was, however, a difference between species in the short wavelength regions of the spectrum.

    Notes: The proband, a healthy primipara, selected for study after she had asserted that she had not previously been pregnant, gave birth to a healthy girl with the karyotype 46.XX In the 21st week of gestation, leukoagglutinin stimulated mitoses from die proband's blood were 99% 46,XX and l% 46.XY. the Y chromosome being identified by its quinacrine fluorescence In two samples taken later in pregnancy no XY mitoses were found in the cultures, but on all three occasions brightly fluorescent Y chromatin in a proportion of the uncultured lymphocyte nuclei showed the presence of XY cells in the proband's blood. High titers of cytotoxic anti-HL-A 3 were detected in the maternal serum before and after delivery. Our tentative interpretation is that the XY cells in the proband's blood emanated from a previous fetus that was legally aborted by curettage on the 10th week of an uneventful pregnancy and which the patient admitted to only after repeated questioning.

    Notes: In the presence of high concentrations of exogenous arachidonic acid (≥ 10 μm). eosinophils produced 15-hydroxycicosatetraenoic acid (15-HETE) in the absence of stimuli. The calcium ionophore A23187, as well as the chemotaxins used in this study-complement split product C5a, platelet-activating factor (PAF). and,N-formyl-methionyl-leucyl-phenylalanine(FMLP)–failed to increase 15-HETE production, indicating that eosinophil 15-lipoxygenase is already active Production of 15-HETE from eosinophils increased with increasing concentrations of arachidonic acid, exogenously added. Maximal 15-HETE production was observed to he 1111 ± 380 ng per 106 eosinophils at the concentration of 100μm of arachidonic acid. With low concentrations of exogenous arachidonic acid (below 2;μm). eosinophils were considered to incorporate exogenous arachidonic acid into their cell membrane, and did not produce 15-HETE. In contrast, 15-HETE formation in highly purified neutrophils (eosinophils 〈 1%) was negligible compared with that in eosinophils (.300-fold less), suggesting that 15 f HETE-forming activity in granulocytes is derived from the eosinophil 15-lipoxygetiase pathway and that neutrophils may lack 15-lipoxygcnase activity.

    Notes: In this study we report on functional characteristics of pustule as well as blood polymorphonuclear neutrophils (PMN) in patient suffering from relapsing bullous staphyloderma. Large numbers of viable PMN from newly formed pustules as well as from the peripheral blood were investigated. During the course of disease chemotactic migration, enzyme degranulation, superoxide-anion generation and leukotriene B4 production were determined simultaneously.The results revealed C5a- and NAP-1/IL-8-specific dysfunction of pustule PMN as compared with blood PMN. In contrast, FMLP-elicited functional activities of pustule PMN were only slightly affected.Our findings provide evidence that in inflamed tissue invading PMN are regulated by in situ generated mediators. C5a produced by staph. aureus-induced activation of the alternative pathway of the complement cascade represents predominant regulatory factor in situ. Furthermore, the results substantiate previous observations concerning different modulation of C5a and f-met-peptide receptors on human PMN.

    Notes: Hybrid cells have been recovered from selective culture medium after fusion of concanavalin-A-activated human lymphocytes with an AKR mouse thymoma (BW 5147). After 6 months of culture twenty-seven out of forty-nine clones still contained human chromosomes. Human chromosome 6 was present in 89% of these clones, and human X in 70%. Clones from one hybrid line contained several human chromosomes. In twelve of the clones carrying human chromosomes, the rosetting with sheep Erythrocytes (SRBC) was 3 times as high as In the BW 5147 cell line. All these clones Carried the human chromosome 6, and eight clones contained the human X chromosome as well. In some of these clones (25%) chromosome 6 was the only human one present. In the two clones In which human chromosome 6 was completely missing, the resetting with SRBC was at the level of the BW line. We therefore suggest that genes on human chromosome 6 are responsible for rosetting with SRBC.

    Notes: In the laboratory, intraocular pressure (IOP) was measured in each eye of two adult Tursiops truncatus and one Grampus griseus. Measures were made in alternation between eyes over a time span. Means and standard deviations were calculated. Mean IOP's ranged from 33.4 mm Hg (SD = 2.4) in the male Tursiops to 24.6 (SD = 2.3) in the female Tursiops. IOP in the Grampus was intermediate. Tonograph functions for the Tursiops over periods greater than 25 min had a cyclic character with maxima and minima. These cycles were fitted with a polynomial function with periods of 15 min (female) and 20 to 26 min (male). There was no significant correlation of the IOP variations with time between eyes in either Tursiops. Compared to humans, these cetaceans exhibit clinical ocular hypertension bilaterally. The range of pressures they exhibit, over time, is much greater than reported previously for several terrestrial mammals.
