WebApr 14, 2024 · The outer and inner dynein arms are composed of motor proteins called dyenins which are responsible for ciliary beat generation. Coordinated ciliary beating, in association with muscle contractions, propels the oocyte through the fallopian tube (FT) to the uterus . The tubal mucous composition and the hormone levels aid this transport . WebCiliary beat frequency (CBF) was measured by a pho-tometric technique, combining a light microscope, a photometer, a photograph-multiplier, and a com-puted analyzing unit. Results: Treatment for 20 minutes with amphotericin B finally diluted in saline to 0.1 mg/mL caused no decrease in CBF. By contrast, both amphotericin B diluted in distilled during-the-sale touch points

WebThe ciliary beat frequency (CBF) was measured sequentially by a photoelectrical method: when specimens were fresh and then at intervals of 1 week, 1 month and 3 months after cryopreservation in liquid nitrogen and thawing. Mean CBF values recorded after thawing did not differ significantly from the values measured before cryopreservation. WebIts intracellular concentration is regulated by purinergic and acetylcholine receptors. Besides the rate regulatory effect of calcium on ciliary beat, calcium is also involved in synchronizing the beat among cilia of one single cell as well as between cilia on different cells.
