Histochemistry and fine structure of the bladder tegument of a larval Multiceps endothoracicus. | Certain differences were found in the histochemistry and fine structure of an active bladder tegument of an infective larva of M. endothoracicus and a regressively changing bladder of an aging larva of this species. The bladder tegument of an aging larva contained an accumulation of acid mucosubstances and phospholipid... | 567,613 | [

Antibiotics from Basidiomycetes. V merulidial, a new antibiotic from the Basidiomycete Merulius tremellosus Fr. | Merulidial, a new antibiotic, was isolated from the culture fluid of the Basidiomycete Merulius tremellosus Fr., strain No. WQ 568. Merulidial inhibits a variety of bacteria and fungi. In cells of the ascitic form of EHRLICH carcinoma, DNA synthesis is inhibited at lower concentration as compared to RNA and protein syn... | 567,638 | [

Placental and foetal weight in the nude mouse. | Placental and foetal weight and litter size were studied on the 18th day of pregnancy in the athymic nude mouse. Placental weight and litter size were unaffected by the absence of a thymus. Foetal weight was reduced, probably as a result of the health status of such animals. | 567,663 | [

Novel mechanisms of reproduction: preimplantational ectogenesis. | The polarization of attitudes concerning preimplantational ectogenesis, combined with the fact that the field is technically in its infancy, makes likely the passage of much time before the use of ectogenesis becomes widespread either clinically or as a research tool.

Activation of hypothalamic neuronal activity by the electrolytic deposition of iron into the preoptic area. | Changes in brain activity after electrochemical stimulation of the preoptic area of pro-oestrous rats were studied by the measurement of the electro-encephalogram (EEG) of the frontal cortex and the recording of single neurones in the anterior hypothalamus. All rats were anaesthetized with urethane between 10.00 and 12... | 568,650 | [
