Influence of growth regulators and nitrogen on the number of endosperm cells in wheat grains from different positions on the ear.

The course of development of the endosperm in wheat grains from pot experiments after application of growth regulators and a varied N-supply was followed by an endosperm cell count. The maximum number of endosperm cells was reached within the third week after anthesis and remained constant at two further checking times for more than 30 days after anthesis. There was no effect of application of CCC and Ancymidol at the end of tillering on the maximum number of endosperm cells although the single grain weight was smaller than in the control. The number of endosperm cells and single grain weight had not been altered by the varied N-supply. Within the ear, there is a distinct relation between the maximum number of endosperm cells and single grain weight. During the course of grain development, the differences in the number of cells, appeared earlier than the differences in the grain weight.

[Bronchial atresia--a rare anomalia (author's transl)]. / Bronchusatresie--eine seltene Anomalie.

Report on three cases of bronchial atresia. Two patients had an atresia of a segmental bronchus with consecutive bronchocele and regional hyperinflation, one patient had an atresia of a lobar bronchus. The diagnosis is made by association of radiologic and bronchologic analysis. Possible pathogenetic mechanisms are briefly discussed.

[Spinal deformities and their mechanopathology in oarsmen (author's transl)]. / Wirbelsäulenveränderungen und ihre Mechanopathologie bei Leistungsruderern.

Motional analysis of the spinal segments with an x-ray amplifyer and studies of mechanical stress in the spine at oarsmen show, that during the phase of driving through with the oars immersed, the direction of the resulting load in the spine is approximately vertical to the next vertebral body. While referring to the vertebral bodies the direction of the resulting load does not change essentially, the size of the load differs conspicuously during active motion. In rowing the quantity of stress in the spine is limited by the torque of the counterforce, the erector trunci. Using an exact and correct rowing technique the quality of stress is compatible with the physiologically axial stresspattern of the vertebral body and the intervertebral disque. The frequency of peakstress in active rowing may possible lead to early and augmented degenerative changes in the vertebral bodies. In 45 Austrian top oarsmen the spine was examined clinically and radiologically, 68% showed signs of a previous Scheuermann's disease, while degenerative changes of vertebral bodies were found in 48%. Comparing spinal damages in different sports used in the training of the examined oarsmen, only in bicycling a similar pathomechanical effect on the spine could be observed.

Antefemoral dissecting cysts in rheumatoid arthritis.

Five cases of an antefemoral synovial cyst in rheumatoid arthritis were confirmed by arthrography. Communicating with the suprapatellar bursa, these rarely observed cysts may be considered an anterior analogy to dissecting Baker cysts.

[Mesothelioma of the peritoneum with pulmonary metastases (author's transl)]. / Peritoneales Mesotheliom mit Lungenmetastasen.

Report of the case history of a female patient suffering from malignant mesothelioma of the peritoneum. Exceptional findings were a dense nodular hematogenic dissemination over both lungs and the duration of disease, which till now extends over 35 months. Pathogenesis, course of disease, diagnosis therapy and epicrisis are discussed.

[Diagnosis of combined malformation of lung and pulmonary vessels (author's transl)]. / Diagnostische Möglichkeiten bei kombinierter Hemmungsmissbildung der Lunge.

Diagnosis of combined malformation of lung and pulmonary vessels are presented in a case of one lobe lung on the right (Agenesis of two lobes and hypoplasia of the presenting lobe). The importance of radioisotope methods in diagnosis of lung hypoplasia is stressed. Pathogenesis and period of teratogenic termination is discussed.

[Thyrotoxicosis and sarcoidosis of the thyroid and the lung (author's transl)]. / Pulmonale und thyreoidale Sarkoidose und Hyperthyreose.

Clinical and pathological studies indicate, that sarcoidosis rarely affects the thyroid gland. The diagnosis of sarcoidosis in the lung and in the thyroid has been established by biopsies taken during surgery in a case of a 53 year old female. The manifestation of thyrotoxicosis in sarcoidosis-involvement of the thyroid has been analysed and compared with the 15 patients exhibiting sarcoidosis-involvement of the thyroid and thyrotoxicosis described in the literature.

[Baker cysts: an accompaniment of chronic diseases of the knee joint (author's transl)]. / Baker-Zyste: Begleitsymptom chronischer Erkrankungen des Kneigelenkes.

One hundred and twenty one Baker cysts demonstrated by arthrography have been analysed. Morphologically one must distinguish between distension cysts and dissection cysts. Distension cysts are more common with various diseases of the knee joint (68% of all cysts). Dissection cysts (32%) are found particularly with inflammatory-rheumatic diseases and are rarely of degenerative or post-traumatic origin. Acute rupture of the cyst was observed on ten occasions. Repeated rupture, which had only been suspected previously, was demonstrated by arthrography in four patients. It is pointed out that Baker cysts may imitate the features of acute thrombophlebitis.

[Roentgenological differention of intrapulmonary findings in patients with hodgkin's disease (author's transl)]. / Intrapulmonale Veränderungen bei M. Hodgkin. Röntgenologisches Erscheinungsbild und Differentialdiagnose.

The spectrum of intrapulmonary findings of Hodgkin's disease is illustrated by 75 pulmonary episodes of 22 patients with Hodgkin's disease (duration of illness up to 14 years). Both the typical and frequent, as well as the rare pulmonary manifestations are discussed. We analysed the time correlation between pulmonary changes and clinical manifestations, and the effect of therapy. This retrospective investigation showed that more than 55% of the observed 75 pulmonary episodes have been diagnosed correctly by the initial radiological examination. By simultaneous appearance of different forms of disease propagation, sideeffect of therapy and superimposed diseases, diagnosis may be impaired.

[The radiological diagnosis of the hemodynamic situation in the pulmonary circulation in chronic obstrictive ventilation disorders]. / Zur radiologischen Erfassung der hämodynamischen Situation im kleinen Kreislauf bei chronisch obstruktiver Ventilationsstörung.

Hemodynamic consequences, especially in view of a developing pulmonary hypertension are essential factors regarding the course and prognosis of an obstructive airflow disturbance. The characteristic roentgen symptoms of pulmonary vascular changes in a group of patients are collected and statistically evaluated to find those symptoms correlating best with the results of cardiac catheterisation. The importantce of using not a single symptom but characteristic groups of symptoms for the radiological diagnosis of pulmonary hypertension is stressed. Radiological signs of increased pulmonary pressure do not directly correlate to the degree of direct measurements, false positive radiological reports need not be expected. Positive radiological symptoms indicate irreversible anatomical changes in pulmonary circulation. For the individual patient the pulmonary arterial pressure by cardiac catheterisation alone is not sufficient for the diagnosis and prognosis of this case as in obstructive air-way disturbance two definitely different types of diseases, namely type A (emphysema) and type B (bronchitis) with divergent hemodynamic consequences must be distinguished. For this differentiation the radiological evaluation of the anatomical situation is essential.

The evaluation of activity of tuberculous lesions in patients with unknown previous course make an additional tomographic assessment of the lesion necessary. The value of this approach is being illustrated by 8 cases.

[Initial X-ray manifestations of bronchial carcinoma. Possibilities and limitations of early diagnosis (author's transl)]. / Radiologische Erstmanifestationen des Bronchuskarzinoms. Möglichkeiten und Grenzen einer frühzeitigen Diagnose.

Problems of defining "early diagnosis" and difficulties, arising from multiform clinical and radiological manifestations in bronchial carcinoma are discussed. Different types of manifestations offer unequal chances for early detection. In demonstrating some typical cases, auxiliary diagnostic means and possibilities for more efficient radiological diagnosis are discussed.
