Ontogeny of "coitus-related" reflexes in the female guinea pig.

Ontogeny of fetal movements in the guinea pig.

Assessment of fetal motility is an approach to evaluate the development and function of the nervous system before birth. Reference values for the time of first occurrence and the incidence of normal fetal movements are indispensable for studies in which prenatal motor activity is applied as a model to study the central and peripheral nervous systems. Studies on fetal motility have been performe...

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...

Some observations on the feeding of the guinea pig

Salbutamol affects body composition of the guinea pig

Activation of neuronal adenosine A1 receptors suppresses secretory reflexes in the guinea pig colon.

The role of adenosine A1 receptors (A1R) in reflex-evoked short-circuit current ( I sc) indicative of chloride secretion was studied in the guinea pig colon. The A1R antagonist 8-cyclopentyltheophylline (CPT) enhanced reflex-evoked I sc. Adenosine deaminase and the nucleoside transport inhibitor S-(4-nitrobenzyl)-6-thioinosine enhanced and reduced reflex-induced I sc, respectively. The A1R agon...
