Acetylcholinesterase (AChE) – Positive Innervation of the Guinea-Pig Spleen

Coexistence of nitrergic and acetylcholinesterase (ACHE)-positive nerve structures of the phaesant spleen.

The coexistence of neuronal NADPH-diaphorase and ACHE activities were investigated in the phaesant spleen by successive double histochemical staining of the same sections. Two types of nerve structures were found in pheasant the spleen: nerve cells and nerve fibres. NADPH-d and ACHE-positive nerve fibres in colocalization enter the spleen in its hilum in the vicinity of splenic artery branches ...

Karyotype of Hairless Guinea pig

Chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. Chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and G banding techniques. The chromosomes diploid number was 2n= 64 and polymorphism of three type chro...

Localization of cholinergic innervation in guinea pig heart by immunohistochemistry for high-affinity choline transporters.

OBJECTIVE Previous studies have used acetylcholinesterase (AChE) histochemistry to identify cholinergic nerves in the heart, but this enzyme is not a selective marker for cholinergic neurons. This study maps cholinergic innervation of guinea pig heart using a new antibody to the human high-affinity choline transporter (CHT), which is present only in cholinergic nerves. METHODS Immunohistochem...
