Distribution of LHRH in the rat and mouse brain with special reference to the tanycytes.

abstract：:During the reproductive period of the male stickleback, structural and functional changes of the kidney take place, both in the glomeruli and in the renal tubule cells. The structural changes in the glomeruli involve almost all glomerular components and point to a reduction of the glomerular filtration rate. The purpo...
