Summary
The development and distribution of ACHE-positive nerve fibres in the spleen of rats and chickens during postnatal ontogenesis was studied by means of a direct thiocholine method based on the presence of acetylcholinesterase (ACHE).
The presence of ACHE-positive nerve fibres in the spleen was proved unambiguously in both species mentioned. The nerve fibres depicted enter the spleen in association with its vessels and are distributed from the perivascular plexuses. Their presence in the spleen of rats is restricted to the white pulp and PALP (periarterial lymph sheath) while in the spleen of chicken these fibres are also distributed in the red pulp and the spleen capsule.
The ageing of rats and chickens results in a decrease in the number and intensity of ACHE-positive nerve fibres in the spleen.
Key words: spleen; innervation; acetylcholinesterase; rat; chicken
