A quantitative description of flagellar movement in golden hamster spermatozoa.
Flagellar movement of golden hamster spermatozoa obtained from the testis and the caput and cauda epididymides was observed by a light microscope while holding them at their heads with a micropipette. Flagellar movement of capacitated spermatozoa and of reactivated spermatozoa demembranated with Triton X-100 was also observed. Testicular and caput epididymal spermatozoa showed weak movement in ...
متن کاملQuantitative analysis of flagellar movement in hyperactivated and acrosome-reacted golden hamster spermatozoa.
Caudal epididymal spermatozoa of golden hamsters were incubated in capacitation medium. Their movement patterns changed as they became hyperactivated and underwent the acrosome reaction. To understand the basic mechanism by which changes in movement pattern are brought about, digital image analysis was carried out on the flagellar movements recorded with a video system. The degree of flagellar ...
متن کاملHistomorphometry of Golden Hamster Ovaries
Introduction: Genital system is important herd in animal's creation. It is necessary for animal reproduction. Mammal has two sex in genital system such as male and female in separated animals. Animal reproduction destroyed by disorder of genital system. In this case, animals cannot produce an animal similar to them. Finally it cause overthrow a species of animals. Methods: Histomorpholog...
متن کاملKinetic studies of the flagellar movement of sea-urchin spermatozoa.
In previous papers (Holwill & Silvester, 1965, 1967) results have been presented which support the hypothesis that the frequency of beating of a flagellum (hereinafter referred to simply as 'frequency') is identical with, or at least proportional to, a rate constant of the first-order chemical reaction which limits the frequency. If, as seems probable (e.g. Bishop, 1962; Brokaw, 1962) adenosine...
متن کاملCharacterization of sulfhydryl proteins involved in the maintenance of flagellar straightness in hamster spermatozoa.
Hamster caput epididymal spermatozoa exhibit a marked 90-180 degree bend when induced to acquire progressive motility in vitro (Cornwall et al, 1988). Flagellar bending is prevented by oxidizing sperm sulfhydryl (SH) groups with diamide. In the present study, the authors examined the SH proteins involved in sperm flagellar bending using two-dimensional polyacrylamide gel electrophoresis and mon...
