Introduction. Vibration as a factor of production is one of the leading that influences negatively on workers in various sectors of the economy. In available literature there no adequate information on the comorbid pathology in hand-arm vibration disease (HAVD) patients. The purpose of the study is to analyze the prevalence of somatic pathology in HAVD patients. Material and methods. The analysis of comorbidity of HAVD patients according in-depth medical data is carried out. The degree of relationship between work-related health disorders is assessed. The results are presented by average values, intensive and extensive indices, the relationship of work-related health disorders is confirmed by the calculation of the relative risk. Results. The main syndrome in the clinical picture of HAVD is autonomous-sensory polyneuropathy of the upper extremities, which is recorded in all patients, while some patients have a combination of two or more clinical syndromes of HAVD. A significant prevalence of diseases of the musculoskeletal and circulatory systems, eyes and its adnexa, ear and mastoid process, digestive, genitourinary system, and respiratory systems was revealed. Number of patients who have diseases of endocrine (up to 25.0%, p <0.01), digestive (up to 43.8%, p <0.01), urogenital (up to 37.5%, p <0.01), respiratory (up to 37.5%, p <0.05) and the circulatory (up to 52.9%, p <0.05) systems grows up with an increase of the experience dose of local vibration. Conclusion. The results of the study can serve as the basis for the implementation of measures for primary and secondary prevention of occupational diseases caused by local vibration, aimed at preventing the development of health disorders.

This paper reports part of a research into the relationship of certain aspects of mental functioning and the psychiatric illnesses of old age. One of the apparent deficits of function to which much importance has been attached is “memory impairment”. This is commonly considered part of various clinical syndromes, especially of the “organic” mental disorder of the senium. The measurement or estimation of memory function is, therefore, thought to be of considerable importance and most clinicians working with elderly patients use some kinds of tests which purport to measure it. There are, however, some points of conflict between clinical usage and the evidence of objective investigations in this area. It has never, for example, been demonstrated in relation to memory assessment that “memory” as such, can usefully be considered as even relatively independent of intelligence in young normal adult subjects (Eysenck and Halstead (1)).

Two cases of the syndrome of webbing of the neck, lymphangiectatic edema, shortness of stature, cubitus valgus and deformities of the toes (symmetric form of the Bonnevie-Ullrich syndrome) are presented. One patient also had elevated urinary gonadotropins and ovarian agenesis. The clinical findings of this syndrome and related conditions are described and the possible mechanisms of pathogenesis are reviewed. The relationship of the Bonnevie-Ullrich syndrome to other clinical syndromes is discussed.

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.

Electron microscopy has proved to be an invaluable discipline in studies on the relationship of viruses to the origin of leukemia, sarcoma, and other types of tumors in animals and man. The successful cell-free transmission of leukemia and sarcoma in mice, rats, hamsters, and cats, interpreted as due to a virus or viruses, was proved to be due to a virus on the basis of electron microscope studies. These studies demonstrated that all the types of neoplasia in animals of the species examined are produced by a virus of certain characteristic morphological properties similar, if not identical, in the mode of development in all types of neoplasia in animals, as shown in Fig. 1.

In RBL-2H3 rat leukemic mast cells, crosslinking IgE-receptor complexes with anti-IgE antibody leads to degranulation. Receptor crosslinking also stimulates the redistribution of receptors on the cell surface, a process that can be observed by labeling the anti-IgE with 15 nm protein A-gold particles as described in Stump et al. (1989), followed by back-scattered electron imaging (BEI) in the scanning electron microscope. We report that anti-IgE binding stimulates the redistribution of IgE-receptor complexes at 37“C from a dispersed topography (singlets and doublets; S/D) to distributions dominated sequentially by short chains, small clusters and large aggregates of crosslinked receptors. These patterns can be observed (Figure 1), quantified (Figure 2) and analyzed statistically. Cells incubated with 1 μg/ml anti-IgE, a concentration that stimulates maximum net secretion, redistribute receptors as far as chains and small clusters during a 15 min incubation period. At 3 and 10 μg/ml anti-IgE, net secretion is reduced and the majority of receptors redistribute rapidly into clusters and large aggregates.
