Neural basis of developing salt taste sensation: Response changes in fetal, postnatal, and adult sheep

Neural basis of developing salt taste sensation: response changes in fetal, postnatal, and adult sheep.

To learn whether salt taste responses change during mammalian development, we recorded from multifiber preparations of the chorda tympani while stimulating the anterior tongue in sheep fetuses, lambs, and adults. Stimuli were 0.5 M NH4Cl, KCl, NaCl, and LiCl, and 0.05-0.75 M concentration series of the first three salts. Ultrastructural studies were made of taste buds at different ages to deter...

Neural basis of sensation in intact and injured corneas.

A renewed interest in the characteristics and neural basis of corneal and conjunctival sensations is developing in recent years due to the high incidence of discomfort and altered sensitivity of the cornea following refractive surgery, use of contact lenses and dry eyes. Corneal nerves are functionally heterogeneous: about 20% respond exclusively to noxious mechanical forces (mechano-nociceptor...

Immunohistochmistry Study of Collagen IV Changes in Glomerular Basement Memebrane During Fetal and Postnatal Periods of Balb/c Mice

Purpose: In this investigation specific antibody type IV collagen has been used in light microscopy to study development of BMG of the embryonic and postnatal mouse glomerular mesangium. Materials and Methods:20 female Balb/C mice were selected randomly and were kept under normal condition, finding vaginal plug was assumed as day zero of pregnancy. 12 pregnant mice were scarified by cervical di...
