A qualitative and quantitative comparison of the ultrastructure of the hepato-cyte lysosomes of adult monkeys, dogs, cats, rabbits, rats, and mice were carried out.
The present study investigated the effect of ammonia on growth and haematological indicators in juvenile soft-shelled turtle Pelodiscus sinensis (initial body weight 3. 05-6. 87 g). After 21 days exposure to ammonia-N (0,10,20,30 mg·L-1) in a static aquatic circumstance,the specific growth rate (SGR,specific growth rate) ,daily food ingestion rate and apparent digestion rate did not change significantly.
Moreover, GDMEC and endothelial-like cell line ECV304 (formally mistaken as human endothelial cell line, possibly derived from bladder carcinoma cells) were compared with their tubule-like structure formation ability in the 3-D collagen matrix.
A comparative observation on the anatomic structures in the leaves of the zygotie, nucellar and parent seedlings from the three cross combinations in citrus was carried out. The experimental results indicated that the rate of the thickness of palisade and the close tissue of the lower part of leaves to the whole thickness of leaves or the index of the thickness of loose spongy tissue were markedly different between zygotic anc nucellar seedlings, and there was a regular relationship among them and their par...
A qualitative and quantitative comparison of the ultrastructure of the hepato-cyte lysosomes of adult monkeys, dogs, cats, rabbits, rats, and mice were carried out.The dense bodies in the hepatocytes in the animals studied were similar in their ultrastructure but different in their number and size. The digestive vacuole was more numerous in rats, mice, rabbits and monkeys than in dogs and cats. But the residue body was scarcely found in rats, mice and rabbits, a little more in cats and monkeys, and quite a ...
The theories and experiments of magnetic excitations in the metallic multilayer films and superlattices are reviewed. The spin wave modes discovered in the double layers and multilayer system by Brillouin Scattering are emphasized. Firstly, the general theory of spin wave modes in the magnetic medium is introduced and then the various methods to observe the spin wave modes are compared.Secondly, the theoretical results on the single film, double layers and multilayer system are summarized and then compared ...
