- 1. Intrafusal muscle fibres of cat tenuissimus spindles have been injected with the fluorescent dye Procion Yellow and identified histologically after recording their changes in membrane potential during 1/sec stimulation of single static or dynamic gamma axons. 2. Thirteen intrafusal muscle fibres innervated by static gamma axons were identified as eight bag2 and five chain fibres. The fact that none proved to be a bag1 fibre is not regarded as significant, for reasons given in the Discussion. 3. In one spindle Procion Yellow was injected into two intrafusal muscle fibres activated by the same static gamma axon; they were identified as a bag2 and a chain fibre. 4. Nine intrafusal muscle fibres innervated by dynamic gamma axons were identified as seven bag1 fibres, one bag2 fibre, and one long chain fibre. 5. In one spindle two bag fibres were injected, one activated by a dynamic gamma axon, the other by a static gamma axon; the former proved to be a bag1 fibre, the latter a bag2 fibre. 6. Stimulation of static gamma axons elicited junctional potentials in seven bag2 fibres and one damaged chain fibre, and action potentials in one bag2 and four chain fibres. In the whole sample of impaled intrafusal muscle fibres (identified and unidentified) activated by static axons, junctional potentials were recorded from twenty‐three (62.2%), and action potentials from fourteen (37.8%). Stimulation of dynamic gamma axons always elicited junctional potentials. 7. In a number of instances it was possible to examine the ultrastructure of motor endings belonging to the stimulated gamma axon. The myoneural junctions of trail endings supplied by static gamma axons to bag2 and chain fibres were both smooth and folded; the deepest and most regular folding occurred on chain fibres. The terminals of p2 plates supplied to bag1 fibres by dynamic gamma axons had smooth myoneural junctions. © 1978 The Physiological Society

- Short-term effects of different amounts of body contact between mother and newborn on human nursing behavior were studied. Extended contact immediately after parturition was related to an increase in affective components of maternal nursing behavior observed on postpartum Days 2 and 4.

- The acute toxicity of twelve solvent extraction chemicals was studied in the albino rat after intraperitoneal injection of the chemicals, and in the rainbow trout (Salmo gairdnerii Rich.) after exposure to the chemicals in the aquaria water. The tested chemicals included the following technical products: one primary aliphatic amine (Primene JM-T), two secondary aliphatic amines (Amberlite LA-1 and Adogen 283), two tertiary aliphatic amines (Adogen 383 and Alamine 336), one quaternary amine (Aliquat 336), two organophosphorus compounds (TBP, tributyl phosphate and HDEHP, di-(2-ethyl)-hexylphosphoric acid), one synthetic carboxylic acid (Versatic 10), one naphthalene-sulphonic acid (NA-SUL AS-50), one substituted oxime (LIX 64N) and one aliphatic alcohol (2-ethylhexanol). The intraperitoneal 96 hours LD 50 in the rat for the tested chemicals varied between less than 50 mg/kg b.w. to more than 5000 mg/kg b.w. Ninety six hours LC 50 in the rainbow trout was not possible to determine for three of the twelve tested chemicals due to their low water solubility. When determined, the LC 50 at 15°C was in the range 0.11–56 mg/l based on the amounts added. The present study discusses the acute toxicity of the chemicals mentioned above, gross pathological changes in the rat and behavioural changes in the fish.
