METHODS:Through 6-8mm scleral tunnel incisions at 9:00-12:00,90 cases(90 eyes) of cataracts were treated with intraocular lens implantation after continuous circular capsulorhexis or turn-on jar form to deal cataract anterior capsule and extraction of lens nucleus.
Re-sults: Postoperatively an anterior capsular opening of 6.5～7.0 mm in diameter with sharp edge could be seen in 48 eyes and the fixation of both loops in the capsular bag was found in 44 eyes (84.6%)in capsulorhexis group and 21 eyes(52.5%)in “canopener”capsulotomy group.
Most embryo sacs degenerated, and only about 4.5% of the ovules contained a normal embryo sac with an egg cell, two synergids, three antipodal, and a central cell containing two polar nuclei.
Reserve nutrients were accumulated by the musculocutaneous sac elements at the procercoid stage and, later, by the glandular and tegumental cells.
New data have been considered concerning the previously unknown intraembryonic hemopoietic organ in mammals, a region of aorta-gonad-mesonephros arising in embryogenesis simultaneously with the yolk sac.
Cytophotometric measurements of Feulgen-DNA were carried out in the nuclei of embryo sac cells of Haemanthus albiflos and Ornithogalum caudatum.
Formation of nonreduced gametes in the embryo sac was induced by low temperature (4-7°C).
The decomposing process of these leaf litters in the Mongolian oak dominated forest was assessed using litter bag method.
It was suggested to carry out multiple peroxidase oxidations of phenols using partially purified peroxidase enclosed in a dialysis membrane bag placed into a solution of a phenol compound containing hydrogen peroxide.
Portable Magnetic Flaw Detector Equipped with a Magnetic Indicator Bag
The design of a magnetic flaw detector with a magnetic bag used as a flaw indicator is discussed.
It is shown that the large-B multiskyrmions given by the rational map ansatz can be described within the domain-wall approximation or as a spherical bag with the energy and the baryon number density concentrated at the boundary.
