Effects of sex steroids on urine-marking activity were studied in male, female, and neonatally androgenized female mice. Urine marking was estimated by suspending ceramic tubes that were connected in a horizontal row with a steel rod into the home cage of an isolated mouse. Intact males showed high marking activity, which was diminished after castration.(More)
Nerve fibers of the human fasciculus gracilis were studied on 10 male cadavers aged 41-97 years using a discriminative staining method and a microscopic image-analyzing system. Our data show that the transverse areas of axons in the human fasciculus gracilis significantly decrease with age, while no significant correlation was observed between the number of(More)
We examined the human mandibular nerve to find differences in the composition of nerve fiber axons between dentulous and edentulous jaws Using Goto's modification of Masson-Goldner's method. We discovered that the edentulous jaw did not contain any large size axons, compared with the dentulous jaw. This can be considered as evidence that the larger fibers(More)
