Clinico-pathological study of chronic thyroiditis (author''s transl)]

Physiological responses to exercise and anthropometry were measured in several groups of physical laborers. The groups included Colombian sugar cane cutters, sugar cane loaders and general farm laborers. In addition, migrant workers and civil service laborers from the United States were studied. The Colombian populations were generally shorter, weighed less and had less body fat than the United States group. The nutritional state of the Colombian groups, as measured by the hematocrit, hemoglobin, serum albumin and total blood protein, appeared normal. The aerobic power of the Colombia populations was significantly larger than the United States groups. The larger aerobic power of the Colombian groups is probably related to greater physical fitness associated with the physical demands of their occupations.     

A genealogical study of Steinert''s disease (author''s transl)]

Kniest's disease (spondylo-epiphyseal dysplasia) was recently described by Maroteaux and Spranger. A second familial case is studied. Transmission of the disease occurred as a dominant trait.     

Experimental study on cancerogenic activity of asbestos filters (author''s transl)]

The concentration of hyaluronic acid which is the fixed loose connective tissue component determining water and other potentials in the interstitium remains constant with age. Since the collagen fiber network in the native tissue state is unstressed, changes in collagen fiber morphology and in collagen content with age have no influence.     

Gall-bladder changes in diabetics (author''s transl)]

The author provides a summary of developments in peer review and Professional Standards Review Organizations (PSROs) within APA, the federal government, and the American Medical Association between June 1974 and June 1975. He discusses the reaction of the medical profession to the interim guidelines from the U.S. Department of Health, Education, and Welfare and the problems of financing PSROs. He concludes that the key issues for PSROs and peer review in general are the availability and effectiveness of local review components, and that lack of involvement on the part of psychiatry will only ensure that nonpsychiatrists will design the review procedures.     

Lambda waves in the neonate (author''s transl)]

Different types of sharp elements can be observed over the occipital regions from the 2nd postnatal week in the open-eyed child, with active eye movement but practically no body movement. Certain of these sharply localised elements in the occipital midlin are identical to adult lambda waves. Their early occurrence calls to mind the emergence of visual function and attention, these latter occurring at the end of the neonatal period between 7 and 9 days.     

Suicides in Santiaco. II. Seasonal variation (author''s transl)]

A very efficient conversion of 1,7-octadiene to 7,8-epoxy-1-octene and 1,2-7,8-diepoxyoctane was achieved by incorporating a high concentration of cyclohexane into the conventional fermentation medium. In the presence of cyclohexane, a 90-ml% conversion of substrate to product was accomplished within 72 h, compared with an 18,5-mol% conversion in the absence of cyclohexane. Furthermore, the products were simultaneously separated and concentrated in the organic phase.     

Adherence phenomena in Trypanosoma congolense (author''s transl)]

Two adherence phenomena in Trypanosoma congolense as a possible cause of trypanosome aggregation in the capillaries of certain organs are described: 1. Adherence of trypanosomes to blood cells of nonimmune mice, 2. dovetailing of trypanosome membranes into one another and into the vessel wall.     

Fibre optic bronchoscopy in children (author''s transl)]

Alterations in the activity of rat liver monoxygenases were studied in dynamics of cholestasis development after ligation of biliary duct and the effects observed were compared to the latter after addition of cholesterol hydroxylated derivatives in vitro. Sodium deoxycholate at concentration 0.06-0.07% was shown to stimulate the alterations in the microsomal monooxygenases activity within fourth day and at concentration 0.09-0.12%--within seventh day of cholestasis.     

Creatine phosphokinase in thyroid disease (author''s transl)]

The mere presence of uterine fibroids is not, since qua non, an indication for their surgical removal. Knowing when not to operate is probably more important for the physician than knowing when to operate. It is easy to fall into diagnostic and therapeutic traps when uterine fibroids are known to be present, especially when they occur concomitantly with a condition such as irregular uterine bleeding, infertility, or pregnancy. The contributions of such conditions to problems in diagnosing and managing fibroids must be kept in mind by the prudent physician; a decision in favor of medical rather than surgical management is often best.     

Oral mucosal grafts in laryngeal reconstruction (author''s transl)]

Thirty-one children with behavioural problems and learning difficulties were allergy tested for sensitivity to salicylates, artificial colours and flavours, eighteen children had a positive response, and 15 of these were given the Australian Version of the Feingold K.P. diet. Ninety-three per cent responded with improved behaviour in the areas of overactivity, distractability, impulsiveness and excitability. Sleep and enuresis problems were resolved partially or completely. This study demonstrates that the aforementioned elimination diet significantly affects behaviour.     

Intraocular pressure in snorkling and diving (author''s transl)]

The in vitro susceptibility of 145 anaerobic clinical isolates and 96 gram-positive aerobic clinical isolates to josamycin, a new macrolide antibiotic, was studied using the agar dilution technique. Ninety-five of the aerobes were susceptible to 1.56 mug or less of josamycin per ml. The median minimal inhibitory concentration of these organisms was 相似文献   

Obliterative angiopathy of placental stem villi (author''s transl)]

Fixed retinae of chick embryos and chicks of the first week after hatching were fractured and examined with the scanning electron microscope. The matrix cells of the retina proliferate up to the beginning of the second week. The migrating cells are oriented in cell cords. This columnar organizaion prevails up to the development of the plexiform layers formed as a consequence of the outgrowth of the dendritic and axonal cell processes. Special attention was paid to the differentiation of the ganglion, bipolar and receptor cells, and the radial fibers (Müller cells). Two main morphological patterns are significant for the organization of the retina during neurogenesis: a)the cell to cell contacts of migrating cells and b)the spatial arrangement of Müller cells which could provide guidelines for migration of neuronal elements.     

Spastic entropion of the upperlid. A case observed in practice (author''s transl)]

A case of multilocular kidney disease is presented and the unusual appearance of tumor vessels is emphasized. The occasional coexistence of multicystic kidney disease and renal cell carcinoma in adults also is mentioned.     

Some features of the control of atrophic rhinitis (author''s transl)]

The results obtained by a number of control measures in 152 cases of atrophic rhinitis in the province of North Brabant in 1975 are reviewed. So-called "elimination of piglets" from the herd for a few weeks and treatment of the newborn piglets in accordance with a fixed scheme are the measures stressed in this regard moreover, when this scheme of treatment is adopted in a contaminated environment, i.e. without any taking over by the authorities, it also offers certain prospects. The method of control widely used in the Netherlands so far (elimination of piglets not followed by a scheme of treatment) was not sufficiently successful.     

Experiences with INHG-Na in the triple-drug-therapy of extrapulmonal tuberculoses (author''s transl)]

It was shown that in the embryos whose fathers had been subjected to x-ray irradiation, there appeared pathological alterations involving all parts of the embryo, resulting in high postimplantation mortality. In contrast to x-ray irradiation, chloridine affecting male gametes did not result in the increased embryonic death rate and disorders in embryogenesis as compared with controls. It permitted a conclusion of the process of rat spermatogenesis being resistant to this preparation.     

Acceleration of ageing processes by ionizing radiation (author''s transl)]

The dynamics of arterial, venous, and lymphatic flow in the mesentery were studied in dogs, using an electromagnetic flowmeter for the blood and cannulation and gravimetric measurement for the lymph. Ligation of veins caused an increased venous outflow in adjacent veins and a marked increase in lymph flow. When marginal vessels were ligated, eliminating the major collateral flow, venous flow decreased, but elevated lymph flow persisted. Simultaneous ligation of arteries and veins resulted in increases of both arterial and venous flow in adjacent vessels. Lymph flow decreased unless excessive arterial collateral flow persisted. When collateral marginal vessel flow was occluded, adjacent venous and arterial blood flow decreased to control levels. With arterial ligation, collateral arterial blood flow increased slightly, but venous and lymph flow decreased sharply. When collateral marginal vessels were eliminated, adjacent arterial blood flow decreased to control levels and venous flow virtually stopped. As a result of these studies, the technic of early primary arterial ligation followed by marginal vessel ligation appears to be the most satisfactory procedure for decreasing venous and lymphatic outflow and hopefully avoiding dissemination of cancer cells during the operation. This technic is now being used as a modification of the "no touch" technic for cancer of the colon.
