Preputial glands, dominance and aggressiveness, in mice

摘要: Abstract The preputial glands are androgen-dependent and apparently used in pheromonal signalling rats mice. With light electron microscopy (LM EM) these from socially dominant subordinated members of pairs male laboratory ‘TO’ strain mice were compared with those individually-housed counterparts. both individually housed animals well-developed actively secreting having acini at different stages maturation numerous normal cytoplasmic organelles healthy oval-shaped nuclei. less developed, had fewer, smaller lipid droplets fewer cellular organelles; the nuclei shrunken lobulated; cells often contained autophagic vacuoles, which also found castrated data suggest that reduced gonadal function typical other two categories exprcsses itself structure function. aggressiveness induce...
