    Notes: [Auszug] In some respects, these observations resemble those of Kohlbrugge2, who claimed to have identified spermatozoa within the uterine mucosa in elasmo-branch fish (Scyllium and Torpedo), the domestic fowl, bats of two species (Xentharpya amplexicaudata and Pterogistes stenopterus) and the rabbit, and ...

    Capacitation of Mammalian Spermatozoa (1958)

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Recently, we have obtained evidence that the acrosome is removed from the spermatozoon head before the entry of the spermatozoon into the egg. Modification and loss of the acrosome have been observed in living spermatozoa of the golden hamster, guinea pig and Libyan jird recovered in the fluid from ...

    Notes: [Auszug] THE wealth of detail in a recent comprehensive review of this subject1 bears witness to the large volume of information which is available on fertiliza-tion and associated phenomena in mammals. Although much of the information is rather disconnected in form, some underlying principles are becoming ...

    The ‘Capacitation’ of the Mammalian Sperm (1952)

    Notes: [Auszug] The conclusion drawn by both workers was that, in rats and rabbits, the sperm must undergo some form of physiological change or capacitation before it is capable of penetrating the egg. The need for such a change in the sperm has not been postulated before on direct evidence, and further ...

    Notes: [Auszug] Recently, the attempt was made to repeat these observations in London, and for the purpose two strains of laboratory rat were used: an albino and a 'hooded' strain. In spite of almost daily trials extending over a period of two months with the albino rats, delayed mating occurred at only two out of ...

    Notes: [Auszug] It has now been found that, after cold-shock treatment, a small proportion of rat eggs will undergo apparent early parthenogenetic development. Cold-shock was applied to the eggs of 130 cestrous rats under 'Nembutal' anaesthesia 8-12 hr. after ovulation. The rats were killed during the succeeding ...

    Notes: [Auszug] In the initial experiments, adult virgin female rats were permitted to mate under normal colony conditions by being placed with males in the afternoon and left with them overnight. Mated rats were recognized by their having a copulation plug when examined the following morning. Sixty-eight mated ...

    Notes: [Auszug] Our investigations have been made on voles that have been bred in captivity for many generations, initially at Oxford and more recently, from the same stock, in London also. At Oxford, control stocks of voles were kept in breeding pairs or in groups consisting of a single litter each. For the ...

    Notes: [Auszug] Of the 108 eggs which contained sperms only in the perivitelline space, the great majority (103) displayed chromosomes arranged in metaphase. In the remaining five eggs, however, the mitosis had proceeded and in three of them the polar body had been formed. These five eggs thus exhibited signs of ...

    Notes: [Auszug] The time of survival differed with individual eggs and also with the degree of pressure to which they were subjected, but was usually not less than six to eight hours or more than twelve to sixteen hours. Within limits, the more the eggs are compressed the greater is visibility improved ; but ...
