[Biology of the volcano mouse (N. a. alstoni). XVII. Blood chemistry of animals born in the laboratory (F1)].

This work reports an initial study of the blood chemistry of young adult (between 129 to 155 days of age), laboratory born (F1) volcano mouse (Neotomodon alstoni alstoni). The blood biochemical values determined were glucose, cholesterol, total bilirubin, total protein, albumin and globulin, as well as the electrolytes sodium, potassium, chloride, calcium and phosphorus. In most of the values there were no differences statistically significant between males and females; only the values of total bilirubin and potassium were slightly higher in females, with differences statistically significant. The values of glucose and cholesterol showed a wide range of variation in the animals of both sexes. Although several studies dealing with the blood chemistry of various laboratory rodents have been published, the experimental conditions in which these investigations were carried out were so different to the ones of the present work that cannot be compared; neither a comparison can be made of the present results with those of the blood chemistry of the members of the Peromyscus genus, which is the most phylogenetically close to the Neotomodon genus, since, as far as we know, there has been no studies reported on this subject on Peromyscus.
