fuorescent retrograde neuronal labeling in rat by means of substances binding specifically to adenine-thymine rich dna.six fluorescent substances, binding specifically to adenine-thymine rich dna, were injected in rat caudate-putamen. this resulted in retrograde axonal transport and fluorescent retrograde labeling of neurons in center-medium parafascicular nucleus, substantia nigra and dorsal raphe. two of these substances, i.e. "true blue' and 'granular blue', give a very striking blue fluorescent retrograde neuronal labeling. mid-thoracic spinal injections of these two substances in rat also resulted in a pron ...197988697
drugs or drums: what relieves postoperative pain?the cybernetic model of analgesia is a simple servo-loop: altered sensory input--complaints--medication--temporary restoration of acceptable processing of the sensory input--return of altered sensations. under ordinary clinical circumstances the functioning of this mechanism is masked by "noise" generated by the interaction of several persons who provide the medication and time factors prolonging the interval between the onset of complaints and the action of the medication. demand analgesia (da) ...200088710
virolysis of mouse mammary tumor virus by sera from breast cancer patients.all type c retroviruses are lysed by human serum in apparently antibody-independent, complement-mediated reactions. in contrast, we have now determined that the mouse mammary tumor virus (mmtv), a type b retrovirus, is not disrupted by normal human serum. mmtv was lysed, however, when rabbit antibody to whole mmtv was added to the serum. by taking advantage of this dependence of mmtv lysis on specific antibody, a virolytic assay was developed, based on the measurement of reverse transcriptase re ...197988736

[immunohistochemical study of the differentiation of the cephalic lobe of the adenohypophysis in chick embryos].it was shown by means of indirect immunofluorescence that acth appeared in the cephalic lobe of the chick embryo pituitary beginning from the 8th day of the development. a new tissue-specific antigen (a3) is revealed, which is localized in the cephalic lobe of adenohypophysis and becomes manifest at the 7th day of embryogenesis. quantitative analysis of acth and a3 localization in the cells of 11-day chick embryo adenohypophyses allows a conclusion that a3 is localized in corticotropic cells.200188969
[nuclear surface of buccal cells as a function of the nature of the stain. measurements with an image analyzing computer].measure of nuclear areas was performed on buccal smears by the quantimet 720 image analysing computer. five different staining procedures were used and we consider that toluidin blue at ph 4 is the best for a fine quantitative caryometry.200188973
the pathophysiology of asthma.because postmortem studies of humans provide little information on the initial pathophysiologic events in asthma, animal models have been developed. recently the ascaris-allergic rhesus monkey has provided an opportunity to examine the onset of pathophysiologic changes following challenge and to correlate them with airway structure. these studies have suggested that the initial interaction between antigen and mast cells may occur in the bronchial lumen or in the epithelium superficial to the tig ...197989006
