Reexamination of spectral mechanisms in the rat (Rattus norvegicus).
The spectral mechanisms of the rat were studied in electrophysiological and behavioral experiments. The photopic electroretinogram (ERG) was recorded (a) to rapidly flickering lights, (b) during the cone phase of dark adaptation, and (c) with a flicker photometric procedure. Each procedure indicated the presence of a single cone mechanism having a lambda max of about 510 nm. Increment-threshold...
متن کاملMilk availability modulates weaning in the Norway rat (Rattus norvegicus).
Two experiments were conducted to investigate the role of milk availability in the development of independent feeding and drinking in the Norway rat pup. Beginning on Day 14 postnatally, pups were exposed to different levels of milk supply by changing litter size from 8 to 4 versus 12 pups (Experiment 1) or limiting temporally the pups' access to a lactating dam to 8, 14, or 24 hr daily (Experi...
متن کاملUterine torsion in a Sprague Dawley rat (Rattus norvegicus).
Uterine torsion is a twisting of the uterus or uterine horn perpendicular to its long axis. We report a case of uterine torsion in an adult breeding Sprague Dawley rat. The rat died a month after her last recorded delivery. Post mortem examination of the rat revealed 270 degrees torsion of the right uterine horn. The uterus contained a single foetus. The liver was pale and enlarged. The rest of...
متن کاملPrevalence of Cryptosporidium in Wild Brown Rat (Rattus norvegicus) Population at Shoushtar, Iran
Background: Cryptosporidiosis is a zoonotic disease with public health importance, especially for individuals with weak immune system, such as children, elderly people and immune suppressed ones. Evaluation of the prevalence of Cryptosporidium in wild rodents such as wild brown rats could help to establish an epidemiological map of Cryptosporidiosis. The aim of the current study was to assess t...
متن کاملComparative autosomal linkage in mammals: genetics of esterases in Mus musculus and Rattus norvegicus.
Recombination between Esterase-4 and Esterase-2 in the rat was not observed in 278 backcross offspring. Es-4 is thus included within the "esterase cluster" in Linkage group V. A new map of this region was constructed and the relationship of the four esterase loci was found to be: Es-4-(9.6+/-1.6 cM)-Es-2, Es-4-(1.5+/-0.7cM)-Es-3. Homology of this region with a region of Linkage Group XVIII (Chr...
