The ultrastructure of the protonephridial flame cell of the freshwater planarian Bdellocephala brunnea.

abstract：:Hypothalamic slices containing the lateral hypothalamic area (LHA) were prepared from 6- to 8-day-old rats and maintained in stationary culture for up to 35 days in order to analyse how well the melanin-concentrating hormone (MCH) neurons survived. As previously reported for other brain areas, this method yielded a lo...
