    Notes: High-purity Al0.3Ga0.7As is grown by molecular beam epitaxy at a high substrate temperature using a superlattice buffer layer in order to trap residual impurities. The unintentionally doped layer is p type with p 〈 5×1014 cm−3. Photoluminescence spectra at 10 K showed the strong bound-exciton emission to be 3.8 meV wide and extremely weak emission due to residual C and Si. Photoluminescence spectra of successively grown single-quantum wells with different widths demonstrate that residual C and Si are mainly trapped at the interface of the first-grown well.

    Notes: Summary To clarify whether activity of the sympathetic nervous system is decreased in streptozotocin-induced diabetic rats, noradrenaline turnover, which is a reliable indicator of sympathetic nervous system activity, was measured in the interscapular brown adipose tissue, heart and pancreas of streptozotocin diabetic rats. Results from studies using inhibition of noradrenaline biosynthesis with α-methyl-p-tyrosine demonstrated significant reductions (p〈0.05-0.001) in sympathetic nervous system activity in the interscapular brown adipose tissue, heart and pancreas of streptozotocin (65 mg/kg) diabetic rats, compared with measurements in streptozotocin (35 mg/kg) diabetic and saline-control rats. The daily injections of neutral protamine Hagedorn insulin to streptoz/otocin (65 mg/kg) diabetic rats prevented the decrease of noradrenaline turnover in the interscapular brown adipose tissue and heart significantly (p〈0.02), but this was less marked in pancreas, compared with non-treated streptozotocin (65 mg/kg) diabetic rats. Furthermore reduced noradrenaline turnover was also observed in the control rats which showed comparable changes in body weight to the rats injected with streptozotocin (65 mg/kg). These results suggest that poorly controlled streptozotocin diabetic rats may have reduced sympathetic nervous function, and that insulin therapy might prevent this.

    Description / Table of Contents: Résumé Description d'une méthode d'enregistrement, durant l'opération, des potentiels d'action des nerfs moteurs efférents (PANM), évoqués par stimulation directe, transcrânienne, de l'aire motrice, au niveau des racines ou des nerfs périphériques. Les enregistrements du PANM au niveau de la racine montrent si la fonction de la racine antérieure est intacte et si sa continuité est conservée. Lorsque l'enregistrement est pratiqué au niveau du segment proximal d'un nerf sectionné au poignet, les fibres motrices peuvent être identifiées, ce qui facilite la réalisation de la suture nerveuse.
    Notes: Summary A method is described which records efferent motor nerve action potentials (MNAPs), evoked by trans-skull motor area stimulation, directly from a nerve root or peripheral nerve fibres during operation. The records of MNAPs from the root show whether function of the anterior root is intact and its continuity retained. When recorded from the proximal stump of a divided nerve at the wrist the motor funiculus can be identified, enabling funicular nerve suture to be carried out more easily.
