Brief depletion which causes only moderate weight loss in other strains results in hyperactivity and convulsions followed by death. Tissue stores of B 6 are not different from normal. Islets of Langerhans enlarged, with increased insulin levels. This is associated with slow growth of the medial septum subadjacent to the cavum septi. Oocytes display retarded kinetics of meiotic maturation and a high frequency of metaphase I arrest.
Some oocytes fail to resume meiosis.
Unusual cytoskeletal and chromatin configurations in mouse oocytes that are atypical in meiotic progression. Responses of seven inbred strains of mice to percutaneous applications of 3-methylcholanthrene. I. Absorption, excretion and conversion of vitamin to enzyme co-factor. Genetically transmitted obesity in rodents. Predatory behaviour in laboratory mice.
