Myopathic changes at the end-plate region induced by neostigmine methylsulfate.

Administration of large dose of neostigmine caused very quickly marked myopathic changes at the motor end-plate region. With continued injections, however, some recovery of the structural features did occur suggesting the reconstructive changes in the affected regions.     

Influence of the visual cortex upon collicular evoked responses in the rabbit.

In rabbit, the depression of the visual cortex by KCl showed an enhancement of the collicular evoked potentials. This enhancement revealed that the visual cortex had exerted a tonic type influence upon the superior colliculus.     

Investigations on the turnover of adrenocortical mitochnodria. VII. Effects of ACTH on the half-life of mitochondria from the zona reticularis of the rat adrenal cortex.

The half-life of mitochondria from the zona reticularis of the rat adrenal was calculated by determining the radioactivity decay curves of the mitochondrial compartment of 3H-thymidine-injected animals, using autoradiographic methods. ACTH was found to enchance significantly the half-life of the organelles.     

Preparation of specific antiserum against Rana esculenta pre-alpha lens crystallin.

Specific antiserum against Rana esculenta lens pre-alpha crystallin was prepared in a rabbit by injecting antigen-antibody precipitate of this crystallin obtained from immunoelectrophoresis of esculenta total soluble lens proteins against homologous antiserum.     

Age and peritoneal fluid cellular distribution in women 20-40 years of age.

Cytologic aspiration specimens of peritoneal fluid revealed that mesothelial cell proportions were significantly reduced 19.2% in women between 26 and 35 years of age. Possibly, mesothelial cell renewal was decreased in women of the older age groups.
