Microchromosomes in the American red fox, Vulpes fulva.

Classification of the cytological activity of phenols and aromatic organophosphates.

Antimitotic effects have been reported for several members of the class of compounds which may be described as the simple substituted phenols (Muhling et al., 1960, Hindmarsh 1951, Levan and Tjio 1948, Loveless and Revell 1949, Clowes 1951). Muhling et al. (1960) showed that complex derivatives such as the phenoxyalkyl acids exhibit an effect on mitosis similar to that of the phenols, and sugge...

A cytogenetic study of 112 cases with Down's syndrome.

(Mikkelsen 1967) -3% (BrƒÓgger 1967); in patients born to mothers younger than 30 years it is 8.3%, and in those born to mothers older than 30 years it is 1.2% (Mikkelsen 1967). Between the patients born to mothers older and younger than 30 years the difference is highly statistically significant. The frequency of D/G translocations is about the same as the frequence of G/G translocations. Abou...

Re-evaluation of the quantity of DNA in cell nucleus of two animal species by microspectrophotometry and autoradiography.

Cytological effects of medicinal plants in Qatar. II. Mitotic effect of water extract of Teucrium pilosum on Allium cepa.

In this survey the effect of water extract of Teucrium pilosum on mitosis of Allium cepa was studied. Teucrium pilosum is a perrenial plant, not grazed by animals and its extract is used natively against constipation and as antispasmotic. Results and discussion Table 1 shows that the extract affected the mitotic index, percentage of phases and percentage of abnormal cells. Inhibition of mitotic...
