[Molybdenum as an air pollutant].

Investigations into the reasons for the retarded growth and discolouration of a small area of a field of rape situated on the outskirts of Vienna revealed higher than normal levels of molybdenum in the soil (up to 430 micrograms/l) and in the water (up to 9.7 mg/l). The source of the pollution was traced to a neighbouring industrial plant that was emitting the metal via the chimney stack. A review of the literature on the toxic effects of molybdenum in general and as an air pollutant in particular is provided. This shows that, in contrast to animals, this effect is relatively small in humans and plants. Nevertheless, the occupation-related inhalation of the metal has been shown to be associated with pneumoconiosis and gout-like symptoms.

Acute subdural hematoma with and without multiple injuries.

A series of 109 patients with clotted subdural hematomas operated on within 72 hours of closed head injuries was evaluated retrospectively. Twenty-seven patients with multiple injuries showed a mortality rate of 77%, those without 59%.

[Importance of MR tomography for the diagnosis of bone marrow diseases in childhood].

As a diagnostic and follow-up method of bone marrow diseases in children, magnetic resonance imaging (MRI) possesses special importance. It is characterised by high sensitivity in detecting bone marrow lesions, high soft tissue--bone tissue contrast, sharp demarcation of intraosseous lesions and visualisation of vascular structures without application of contrast medium. Thus it is able above all to take on the findings of radionuclide bone scanning, computed tomography and angiography. In the detection of pathophysiological alterations of the corticalis and of calcifications it is less reliable than x-ray images and CT.

Blinking patterns in soft contact lens wearers can be altered with training.

The blinking patterns of 15 soft contact lens wearers were recorded with a concealed video camera. Each of 20 consecutive blinks were graded, during slow motion replay of the video, as either complete, incomplete, forced, or twitch. Ten of these subjects were instructed to perform blinking exercises for a period of 2 weeks and the remaining 5 subjects acted as controls. After these exercises all the experimental group displayed an increased frequency of complete blinks, whereas the blinking patterns of the control group remained unchanged. Blinking exercises are likely to alleviate many of the signs and symptoms associated with incomplete blinking amongst contact lens wearers.

[Virus-like particles in yeast protoplasts. I. Electron microscopic demonstration].

In ultrathin sections and negatively stained isolates from protoplasts of a strain of Saccharomyces cerevisiae showing abnormal morphology and degeneration phenomena the presence of virus-like particles within the cells could be demonstrated. The isometric particles have diameters of about 50 nm, the electron dense centre is surrounded by distinct envelope. Protoplastic containing up to 30,000 particles could be found. It could be demonstrated that there exists a correlation between the amount of particles and the degree of degeneration of the cellular substructure. Protoplasts with high titres of virus-like particles obviously undergo lysis. Plaque formation on agar plates could not be seen. It is concluded that the phenomena observed can be compared with cytopathological effects caused by viruses in other cell systems.
