Notes on a Large Scrotal Hernia Operated upon under Apothesine

an operation. He was discharged the next day. On 6th December,. 1924, the patient again sought admission. He came in with a very severe attack of bronchial asthma. The hernia had very appreciably increased. A little difficulty was experienced in effecting its reduction. He again expressed unwillingness to be operated upon. A truss was applied and the patient discharged. On 2nd February, 1925, t...

Anthraquinones of the roots of Pentas micrantha.

Pentas micrantha is used in the East African indigenous medicine to treat malaria. In the first investigation of this plant, the crude methanol root extract showed moderate antiplasmodial activity against the W2- (3.37 μg/mL) and D6-strains (4.00 μg/mL) of Plasmodium falciparum and low cytotoxicity (>450 μg/mL, MCF-7 cell line). Chromatographic separation of the extract yielded nine anthraquino...

Chromosome Behavior and Nuclear Development in Tradescantia.

COMPARISON of microsporogenesis and microspore development A in a triploid Tradescantia has shown significant deviations from the normal diploid behavior. Occasional dicentric chromatids a t meiosis are found in diploid Tradescantias, but inversion crossovers in the triploid are much more frequent. An analysis of microspore development in a triploid Tradescantia shows that chromosome number has...

Segmental Interchange in Chromosomes of Tradescantia.

Chromosome ring formation has been found in a number of difierent genera. In certain species of Oenothera and of Hypericum and in the monotypic genus Rhoeo, all the chromosomes may be united in a single ring or chain a t meiosis. Ring formation is maintained in these plants by a system of balanced lethals. In Datura, Zea, Pisum and Campanula rings of four or more chromosomes have been described...
