Development of coliphage T5: ultrastructural and biochemical studies.
Electron microscopic studies of Escherichia coli infected with bacteriophage T5(+) have revealed that host nuclear material disappeared before 9 min after infection. This disappearance seemed to correspond to the breakdown of host deoxyribonucleic acid (DNA) into acid-soluble fragments. Little or no host DNA thymidine was reincorporated into phage DNA, except in the presence of 5-fluorodeoxyuri...
متن کاملHistological, ultrastructural and biochemical studies on the kidney of mice treated with Carthamus tinctorius L. extract
Objective: Carthamus tinctorius L.(C. tinctorius) is used as a food additive but also has medicinal applications. The present work was designed to investigate its probable side effects on the histology and function of the kidney in the mice. Materials and Methods: Sixty adult Balb/C mice were randomly distributed into one control and three experimental groups. The control group received only di...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Dissociation and reassociation of trichocyst proteins: biochemical and ultrastructural studies.
Trichocysts, the crystalline exocytotic organelles in Paramecium tetraurelia, are composed of small, acidic proteins existing primarily as disulphide-linked dimers. We have disaggregated trichocyst proteins with heat, simultaneously observing the changes in morphology and protein composition. The tip matrix was most heat-labile; its subunits progressively broke away from the distal end. During ...
