K transport has been investigated during progression of cultured Ehrlich ascites tumor cells through the cell cycle. Using a double thymidine block technique, Ehrlich cells carried in continuous culture have been synchronized, as verified by simultaneous monitoring of cell number, cell volume, 3H-thymidine incorporation and mitotic index. Unidirectional influx, efflux and cell content of K have been monitored throughout the cell cycle. The nature of the pump mediated, ouabain-sensitive K flux and the furosemide-sensitive component of K flux, presumably representing K-K exchange, have also been evaluated. In early S period the ouabain sensitive component, representing the Na-K pump, comprises 52% of the total unidirectional K influx and subsequently declines during G2 period to a minimum of 40% in mid G2. During M and early S the activity again rises. As the ouabain sensitive component becomes maximal in late S period, the furosemide sensitive component diminishes from approximately 30% of the total influx to approximately 10%. The same pattern is observed in the G2 period. As the pump component diminishes, the furosemide sensitive component increases. Furosemide sensitive K efflux has also been monitored and the pattern is equivalent to that observed in the invlux studies. No change in net K flux is observed in the presence of furosemide. This indicates that the furosemide sensitive component represents an exchange component for K. These results are consistent with the conclusion that the alterations in exchange and pump fluxes are physiological events associated with progression of the cell cycle.     

Creatinine during pregnancy (author''s transl)]

A report is present of 1300 unselected patients investigated for breast cancer by liquid crystal thermography. The value of this method is comparable to the value of mammography, since the number of carcinomas which remained undetected by each diagnostic procedure was equal. The high degree of diagnostic accuracy achieved by the use of liquid crystal thermography indicates that this simple dignostic procedure is recommendable as a screening method for the detection of breast cancer in gynaecological practice.

The structure of developing rat testes was studied by light and electron microscopy. Ultrastructural differentiation of Sertoli and Leydig cells was followed from 14 days of gestation through birth. Specialized morphology in Sertoli cells was first seen at 16 days of gestation. In these cells the rough endoplasmic reticulum increased and became organized as numerous short cisternae loaded with a homogenous material. Typical Leydig cells were found among the stromal cells, around day 17 of gestation. There is good correlation between the time of appearance of ultrastructural specialization and published data on secretory capacity of the fetal testes, in respect to the inhibition and differentiation of the Müllerian and Wolffian ducts.     

Schizophrenia and its hospitalization (author''s transl)]

Radionuclide dacryography (RND) has the following indications: 1. Localisation of obstructions in the lacrimal drainage system. 2. Judgement of relative tear obstruction. 3. Pre- and post-operative control of the function of lacrimal drainage in surgical and radiotherapy of the inner canthus region. 4. Investigations of tear secretion are described and own preliminary results are discussed. 5. Resorption of suitable marker substances clinically. First results of conjunctival resorption of pertechnetate are reported. 6. The possibility of testing in vivo radioactive drug delivery systems is shown by means of own investigations. 7. The absorbed radiation dose using RND is very low as compared to radiological methods, thus justifying repeated controls and investigations even in children.     

Iatrogenic evolutive skull fracture (author''s transl)]

A case of growing skull fracture secondary to a maxilofacial operation is reported. Frequency, clinical symptoms, phisiopathology and treatment of growing skull fractures are reviewed and the rarity of the iatrogenic mechanism is stressed.

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.     

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.     

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.     

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.     

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.

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   

Determination of the activity of peptidases and amino acid aryl amidases (author''s transl)]

The anatomical condition and the pathomechanism of varicoceles are outlined. The results of the controls of 100 patients being operated by the technique according to Palomo are evaluated. A definite improvement is pointed out in the different parameters of the spermiogram. The differences are significant in follow-up periods up to two years. In the age group between 30-34 years the results are more satisfactory than at the age group 25-29 years and 35-39 years. Half a year after the operation the spermatozoal number generally resembles the norm (40 mill/ml). Catamnestic inquiries among ninetyfive cases showed that there were twentynine graviditis (= 30.5%), which led to a delivery at term in twentyfive cases (= 25.2%).     

A genealogical study of Steinert''s disease (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.     

Experience with a one-stage hypospadias repair (author''s transl)]

In order to assess the relative significance of precordial ST-segment elevations and depressions, 32 patients with anterior transmural myocardial infarction were studied utilizing serial 49-lead precordial maps. Theoretically, zones of ST-segment depression adjacent to major zones of ST-segment elevation might represent border areas of mild ischemia, and hence could be more readily amenable to intervention therapy. As expected, an extensive zone of ST-segment elevation was observed precordially in each of these patients. However, zones of ST-segment depression in adjacent areas were noted to occur inconsistently, were limited in distribution and magnitude, and bore no fixed relationship to zones of ST-segment elevation. Thus, mapping of precordial ST-segment depression in anterior transmural infarction probably has a limited role in assessing evolution of ischemic injury or therapy in these patients. This finding does not, however, vitiate the significance of ST-segment depressions in angina, intermediate coronary syndrome, or non-transmural infarction, conditions which may deserve further study using mapping techniques.     

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.
