    Notes: The hibernating habits of Citellus lateralis under standard laboratory conditions are described. It has been shown that it is possible to use a biopsy technique to investigate the brown fat tissues without serious disturbance to the hibernation pattern. This technique was used to sample brown and white fat tissues in the same animal at various seasons of the year. Histological studies did not reveal any changes in morphology or lipid composition which could be related purely to the hibernating season, however, during the short periods of arousal a large proportion of the brown fat cells appeared to be partially depleted of neutral fat. At this time a large increase in Luxol fast blue staining was always observed, which may be due to unmasking of tissue phosphatides.

    The glyceride fatty acid composition and lipid content of brown and white adipose tissue of the hibernator Citellus lateralisThis project was supported from a grant from the Medical Research Council of Canada. (1966)

    Notes: Glyceride and total phosphatide levels of brown and white fat of Citellus lateralis have been followed throughout the year in biopsy samples.Extraction of the glycerides for fatty acid analysis is described. As much as 20% of the phosphatide of brown fat was found in the upper fat layer of a centrifuged tissue homogenate. This phosphatide appeared to be present as a low-density lipoprotein, and may be associated with the lipid globules of the intact cell.Glyceride and phosphatide levels varied considerably in brown fat, and no particular level was consistently observed to be associated with any part of the hibernation cycle. Fatty acid composition of the glycerides also varied widely. The degree of unsaturation was not related to the hibernation cycle, although there appeared to be a differential utilization of fatty acids during a few weeks prior to spring arousal.A decrease in tissue glyceride levels was observed in both brown and white fat during arousal from hibernation at 2°C, the loss from brown fat being double the loss from white fat.

    Experimental coxsackie B-3 virus infection in Citellus lateralisThis project was supported from a grant from the Medical Research Council of Canada. (1966)

    Notes: Coxsackie B-3 virus produces a mild infection which passes unnoticed in the non-hibernating Citellus lateralis. A severe infection occurs in the hibernating animal. The progress of infection in the hiberating animal is related to the number of arousal hours and quite independent of the number of infected days. Nevertheless, it has been shown that the low-temperature hibernation phase has a potentiating effect upon subsequent viral production. Infective virus has not been found in the inoculated brown fat pads during the hibernation phase but very high virus titers are recorded 48 hours after arousal. This results in an earlier viraemia and earlier and higher titers in other organs of the body. A similar effect is noted when virus is inoculated at the very beginning of the arousal phase. While most animals recover with subsequent antibody development, a few succumb. Antibody development is slow and related only to the number of arousal hours experienced.Particular note is made of the fact that an animal may successfully resume hibernation despite complete loss of the axillary brown fat pads.

    Notes: The phase diagram for the ternary system ammonium nitrate(AN) with 15 wt% potassium nitrate(AN:15KN)-ethylenediamine dinitrate(EDD)-nitroguanidine(NQ) has been determined from room temperature to the melting point. The ternary eutectic temperature, measured for a mixture containing 67.24, 25.30, and 7.46 mole% of AN:15KN, EDD, and NQ, respectively, was found to be 98.9 ·°C. The binary phase diagrams for the systems AN:15KN-EDD, AN:15KN-NQ, and EDD-NQ were also determined.
