We compared the horizontal optokinetic reaction (OKR) and response properties of retinal slip neurons in the nucleus of the optic tract and dorsal terminal nucleus (NOT-DTN) of albino and wild-type ferrets (Mustela putorius furo). In contrast to pigmented ferrets, we were unable to observe OKR in albino ferrets during binocular and monocular viewing using random dot full field stimulation and e...

A simple method was developed to permit albino plant regeneration from anther culture of Hobigonj Boro (Hbj B) IV and Hbj B VI, two local varieties of aromatic indica rice from Bangladesh. Three crucial factors were identified for the albino shoot primordia to change into green plantlets in culture; components of M10 induction medium, callus size (range 0.2-0.4 cm long) and height of shoot prim...

Albino mice and rats have elevated dark-adapted thresholds compared to normally pigmented animals. The absolute dark-adapted incremental threshold for black mice is about 1.5 log units lower than the threshold for albino mice when measured by single-unit recordings from the superior colliculus. Cell counts from the outer nuclear layer in albino mice are not significantly different from those in...

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: encephalitozoon cuniculi is a microsporidian parasite commonly found in rabbits that can infect humans, causing encephalitozoonosis. our objective in this study was to evaluate the seroprevalence of this parasite in rabbits and humans in china. methods: overall, 300 serum samples each from clinically healthy rabbit and hu-man were collected from three regions of china (sichuan provi...
