Myofascial pain dysfunction and viola playing.

Two cases are illustrated to demonstrate the importance of occupation, in the form of viola playing, in the aetiology of myofascial pain dysfunction. An understanding of the contribution of tension and playing style, together with physical limitations, is emphasised and, consequently, it is acknowledged that modification may be necessary to the formulation of a treatment plan.

Dermatoses of the neck affecting violin and viola players ("fiddler's neck", and contact dermatitis).

Skin lesions occurring on the neck of violin or viola players are described, in the light of two personal observations. The lesions can be divided into two types: 1. Lesions described as "fiddler's neck", i.e. an area of erythematous, sometimes pigmented or scaly lichenification on the left side of the neck, just below the angle of the jaw, where the chin rest of the instrument is in contact with the skin. Histopathologic features of the lesions are described. 2. Allergic contact dermatitis to wooden or metallic parts of the violin. The recent literature is reviewed.

[An ecological and geographical test of the seed offspring of Viola matutina Klok. from a 30-kilometer area of the accident at the Chernobyl Atomic Electric Power Station].

The generation of seeds of two populations of Viola matutina Klok. sampled from plants growing within the thirty-kilometers zone of the Chernobyl accident (the reproduction of seeds in 1988) was investigated in the north nursery in Syktyvkar. The decrease of sterile pollen and embryonic lethality among the plants from the strongly contaminated site (exposure rate (1075-1434) pC/(kg.s) May 1987) was registered. It is suggested that this phenomenon is the result of the elimination of genetic damages in the course of seed forming in this population under radiation stress.

Aldose reductase inhibitory effect by tectorigenin derivatives from Viola hondoensis.

Aldose reductase (AR), the key enzyme of the polyol pathway, is known to play important roles in the diabetic complication. The inhibitors of AR, therefore, would be potential agents for the prevention of diabetic complication. The AR inhibition activity of several isoflavonoids was evaluated in vitro against rat lens. Tectoridin-4'-O-beta-D-glucoside exhibited strong AR inhibition activity on rat lens with an IC50 of 0.54 microM. Similar activities were recorded for the natural tectorigenin and tectoridin. In contrast, tectoridin-4'-O-beta-D-glucoside showed a stronger inhibitory activity than tectorigenin and tectoridin. Our results indicate that glucose conjugation position in this type of isoflavonoids may be required for the activity.
