Absence of [125I] alpha-bungarotoxin binding to motor nerve terminals of frog, lizard and mouse muscle.
The existence of nicotinic acetylcholine receptors (AChRs) on the motor nerve terminals of vertebrates has long been controversial. We have re-examined this issue by electron microscope autoradiography with [125I] alpha-bungarotoxin, following separation of nerve terminals from muscle fibers by collagenase and protease treatment. We found no label over nerve terminal membranes other than that d...

15 صفحه اولAlpha-bungarotoxin binding in cat carotid body.
The carotid body is an arterial chemosensory organ which detects changes in blood gas tensions and pH, and reflexly contributes to the cardiorespiratory adjustments which occur during hypoxia, hypercapnia and acidosis. However, the sensory mechanisms involved in carotid chemoreception remain to be elucidated. Morphologically, the carotid body consists of an association of elemental units, or gl...
متن کاملAssessment of the Specific Activity of Alpha- and Beta-emitting Radionuclides in Groundwater, Anka, Nigeria
Introduction: After the lead poisoning outbreak came to light in Zamfara State, Nigeria, people living near gold mines were worried about environmental safety, especially drinking water quality. This study examined the gross alpha and gross beta activity concentrations in groundwater in different locations of Anka, Zamfara State, Nigeria, to measure the possible radiation dose and potential hea...
