Inbred fischer rats were set aside as nonbreeders specifically to obtain tumors of endocrine
organs and endocrine-responsive tissues that might be used in studies of hormone …

Spontaneous testicular interstitial (Leydig) cell tumors arising in our colony of inbred Fischer
rats proved to be readily transplantable. The hormone production and hormone responsivity …

The fur of homozygous ee (recessive yellow) mice is clear yellow. Prior to weaning there is
some dorsally concentrated umbrous sootiness in the coat, but an over-all yellow coat …

Mice from Ha:ICR noninbred Swiss stock were mated brother × sister for 21-25 generations
and then maintained up to the age of 33 months. Hepatomas developed in 62.8% of 86 …

Five Leydig cell tumors from BALB/c mice and 2 mammary gland tumors, one of C3H and the
other of (C3H x A) F z origin, have manifested progressive growth in untreated allogeneic …

Changes in phenotypic expression of immunogenicity often contribute to survival of cells or
tissues that other-wise would be eliminated by an im-mune reaction. Such cellular adapta-…

Over the past 3 years, we have demonstrated that prolonged exposure to hyperbaric oxygen
(HBO) results in modification of several cell-mediated processes. Daily oxygen treatment of …

Although some in-vitro-altered (IVA) tumors are serially transplantable in allogeneic hosts,
such tumors will not grow if the host has been sensitized by skin or by conventionally …

Observations of thyroid follicle epithelial heights and diameters were analyzed with respect
to age and parity in C3H and C57 mice. Epithelial heights decreased and follicle diameters …
