1. Rates of oxygen consumption of albino and hairless mice were measured in a metabolism chamber during periods of approximately 5 or 24 hr. Rectal temperature was measured before and after each period. The chamber temperatures used were 22, 30 and 32 degrees C for both albino and hairless, and in addition 34 and 36 degrees C for the hairless mice.2. The mean age and body weight of the albino m...
Retinal projections were examined in two tyrosinase-negative albino cats using autoradiographic techniques. Cats from this colony have pink eyes; their retinal pigment epithelium, ciliary body, and iris epithelium are completely devoid of melanin pigment. Test breeding for five generations indicates that these cats are true albinos (cc). The most striking feature of the albino cats' visual path...
Background Hamsters are increasingly popular as domestic pets. Different species can be found in the domestic setting: the Syrian (golden) hamster (Mesocricetus auratus), the European hamster (Cricetus cricetus), the Siberian hamster (Phodopus sungorus) and the Rhoborovski hamster (Phodopus roborovskii). Several cases of asthma upon contact with hamsters and anaphylaxis following hamster bites ...
Rabbits were immunized against the plasminogen activator released by SV4- virus-transformed hamster embryo cells. The resulting antiplasminogen activator immunoglobulin (APA-IgG) inhibited the enzymatic activity of the plasminogen activator produced by SV40-transformed hamster cells, and the plasmin-catalyzed release of these cells from the tissue culture dish. APA-IgG was not cytotoxic for t...
BACKGROUND An increasing number of asthma cases upon exposure to hamsters and anaphylactic reactions following hamster bites are being reported, but the allergens responsible are still poorly characterized. In the Golden hamster, male-specific submaxillary gland protein (MSP), a lipocalin expressed in a sex- and tissue-specific manner in the submaxillary and lacrimal glands, is secreted in the ...
Small carnivores are susceptible to regularly accumulating small- medium-sized mammal remains in both natural and archaeological sites. However, compared nocturnal birds of prey, these accumulations still poorly documented generally based on a limited number samples, including those relatively small size. Here, we present an analysis European hamster from rescue excavation at Ittenheim (Bas-Rhi...
The first report of a methylcholanthrene-in duced transplantable melanotic tumor in a Syrian golden hamster was published by Shubik and asso ciates (14). Spontaneous hamster melanomas have been reported by Fortner and Allen (1) and Greene (5). Shubik found that no metastases occurred even when the tumors attained a size of 4 cm. in diameter. Fortner and Allen, and Greene reported diffuse metast...
