Publisher Summary This chapter discusses polyenes in clinical use and those polyenes with
properties that contribute to the understanding of the mechanism of action of the group as a …

To present a coherent and meaningful survey of scientific research endeavour in an area
that has expanded as fast as physiology and biochemistry of reproduction in the male is no …

Bovine epididymal spermatozoa incubated aerobically in vitro in the presence of 0.1 to 0.2
mM CaCl2 accumulate 25 to 50 nmol of calcium/10 (8) cells. The addition of low …

The effect of light on calcium transport in mammalian sperm mitrochondria and plasma
membrane was studied. Digitonine-treated spermatozoa and plasma membrane vesicles …

Optically black, thin lipid membranes prepared from sheep erythrocyte lipids have a high dc
resistance (Rm≅ 108 ohm-cm2) when the bathing solutions contain NaCl or KCl. The ionic …

Bovine spermatozoa, maturing in the caudal epididymis, apparently have a low content of
mobilizable Ca 2+(6±1 nmoles Ca 2+ 10 8 cells) in situ, but will accumulate added Ca 2+ …

Various factors that influence the cytotoxic effects of bilirubin, a known electron-transport
poison, on mammalian cells in culture have been studied. The cellular uptake of free …

Hypotonic treatment of rabbit epididymal spermatozoa in 10 mM phosphate buffer disrupts
the plasma membrane and removes the cytoplasmic droplet from those cells to which it is …

Treatment with the polyene antibiotic, filipin, renders the spermatozoan cell membrane
permeable to small molecules, but not to the intracellular enzymes aldolase and lactate …

Bovine spermatozoa accumulated a small amount of 32Pi during aerobic incubation in vitro.
At least 50% of the acquired isotope rapidly entered cellular nucleotides. Both adenosine …
