Abstract

The effect of light on calcium transport was studied. Bull sperm cells were irradiated with an HeNe (630 mm) laser and a 780 nm diode laser at various energy doses, and ⁴⁵Ca²⁺ uptake was measured by the filtration technique. It was found that there is an accelerated Ca²⁺ transport in the irradiated cells, which means that laser light can stimulate Ca²⁺ exchange through the cell membrane. This may cause transient changes in the cytoplasmic Ca²⁺ concentration which, in spermatozoa, has a regulatory role in control of motility and acrosome reaction, and in other cells can trigger mitosis.
