“…The brown fat deposits in the internal thoracic and abdominal region of the bat are insignificantly different in their topography and vascularization from the deposits in this region which have been described previously in the deer mouse (10). For this reason, only the seven deposits in the external thoracic and cervical regions will be described here.…”

“…The first paper (10) presented such a description for a nonhibernator (deer mouse, Peromyscus maniculatus) and this paper does so for a hibernator (little brown bat, Myotis lucijigus.) Smalley and Dryer have recently reviewed the subject of brown fat in hibernation (1 1) and have emphasized the important role brown fat plays in arousal thermogenesis.…”

Thirteen identifiable deposits of brown fat occur in the little brown bat, Myotis lucifugus. Drawings of these deposits and their vascular supply are presented. Blood vessels were distinguished during dissection by filling the circulatory system with methyl methacrylate. The findings demonstrate the potential of brown fat to transfer heat efficiently to the blood during arousal from hibernation, thereby providing further evidence in support of a thermogenic role for this tissue.

Changes in the composition and morphology of interscapular brown adipose tissue (BAT) are described for the adult pigmy mouse, Baiomys taylori, in its short-term, cold-torpor cycle. The study includes an analysis of tissues from, (1) room temperature (RT) controls, (2) RT, 24 hour starvation animals, ( 3 ) mice exposed on 1 5°C for six hours, (4) torpid animals (24, 48, and 72 hours at 15"C), and (5) mice allowed to arouse from torpor at RT for 1, 2, 5, 9, 24, and 288 hours. Control brown fat is composed predominately of lipid vacuoles, glycogen particles, and mitochondria with lamellaelike cristae. Starvation at RT has no marked effect on either the BAT energy stores, or the mitochondria1 morphometry. Short exposure to 15°C brings about a pronounced depletion in the lipid and glycogen content, and a significant swelling in the mitochondria. Brown fat from torpid mice is deplete of lipid and glycogen. Mitochondria remain enlarged, and have parallel, closely-packed cristae. The lipid and glycogen reappear in the early hours of arousal. The multilocular character of the control BAT is reached in five to nine hours after initiation of arousal. Throughout the arousal the mitochondria retain their cold-induced morphological a1 terations. Pinocytotic microvesicles in the capillary endothelium and in the brown adipocytes are observed in different degrees, i n all experimental groups. With the histological changes in evidence, the participation of pigmy mouse brown fat i n non-shivering thermogenesis in situations of cold exposure, and arousal from torpor, is discussed.
