ABSTRACT
7-Methoxy-, 7-methyl- and 6-methylcoumarins retarded mitosis in Allium cepa root promeristem and caused chromosomal aberrations. Chromosomes became shorter and thicker, and often were lost during anaphase, forming micronuclei during interphase. Chromatid bridges were observed in anaphase and telophase, leading to the formation of a restitutional nucleus, often of irregular shape. Abnormal fragmopasts, often discontinuous, prevented normal cytokinesis. There was increased vacuolization and the mitochondria contained an electron-dense matrix. Parts of the cytoplasm, which were surrounded by ER cisternae, contained mitochondria and pieces of ER membrane. Autophagous vacuoles showed a lower density of cytoplasm, but still contained numerous pieces of ER cisternae.
ABSTRACT
Presurgical cystograms of prostatectomized patients were compared as regards their diagnostic and prognostic usefulness. Because of the lack of fully objective prostatic adenoma symptoms, the authors concluded the distance between the urinary bladder and symphysis pubis to be an important radiological symptom in prostatic adenoma, being the measure of inflammation of the prostate and tissues of this region.

A statistical analysis of intraoperative and early postoperative bleedings in cases of surgery for prostatic adenoma is presented, consideration being given to the surgical technique and to lethality. It has emerged that all patients having had intraoperative or early postoperative bleedings had been operated on by the Hryntschak method and all were over 60 years of age (average age 68 years). Age-matched patients operated on by the Freyer method had no major bleedings.
