    Notes: Summary The progression of subclinical polyneuropathy over 2.5 years has been studied in a representative group of 75 young patients with Type 1 (insulin-dependent) diabetes (initial age 16–19 years). The relationships between changes in nerve function, glycaemic control and concurrently developing microvascular complications (retinopathy, microproteinuria) were investigated. Deterioration of motor, sensory and autonomic nerve function, retinopathy and microproteinuria was related to poor glycaemic control. In addition, there was an association between developing neural and microvascular complications which was not diminished when their common relationship to hyperglycaemia was taken into account. These findings suggest that, although poor glycaemic control is an essential permissive factor in the early development of diabetic polyneuropathy, other influences, shared with microvascular complications, must also be important.

    Notes: Abstract Scent marking with specialized skin glands is a common behavior in the tamarin,Saguinus fuscicollis. The scent marks identify species, subspecies, gender, and individual, and they also contain information on the social position and hormonal condition of an animal. The marks are chemically complex, containing a large number of compounds. Analysis by means of gas chromatography-mass spectrometry has identified 16 major components (squalene and 15 esters of butyric acid). These compounds are present in the marks of males and females of two subspecies,Saguinus f. fuscicollis andSaguinus f. illigeri. Application of computerized pattern recognition techniques has shown that concentration patterns of some of the butyrates are diagnostic of the two subspecies while concentration patterns of other butyrates are diagnostic of males and females regardless of subspecies. Behavioral studies have shown that the concentration patterns of butyrates and squalene alone do not encode information on subspecies and gender. It is, however, likely that this information is partially encoded by these specific butyrate-squalene concentration patterns but that yet unidentified compounds in the scent marks serve as necessary synergists.
