Oral administration of penicillin suspended in equal parts of corn oil and lanolin extends the maintenance of the penicillin level in the system (as determined by urine bio-assay). Measurable quantities were found 24 to 42 hours after ingestion. Recovery of the penicillin is about five times higher
The literature indicates that the tip of maize (Zea mays L.) coleoptiles has the localized functions of producing auxin for growth and perceiving unilateral light stimuli and translocating auxin laterally for phototropism. There is evidence that the auxinproducing function of the tip is restored in
Elongation growth of intact, red-light grown maize (Zea mays L.) coleoptiles was studied by applying a small spot of an indole acetic acid (IAA)-lanolin mixture to the coleoptile tip. We report that: (a) endogenous auxin is limiting for growth, (b) an approximately linear relation holds between
The aim of the present study was to investigate the relationship between formulation/process variables versus the critical quality attributes (CQAs) of cyclosporine ophthalmic ointments and to explore the feasibility of using an in vitro approach to assess product sameness. A definitive screening
Growth of a zone of maize (Zea mays L.) coleoptiles and pea (Pisum sativum L.) internodes was greatly suppressed when the organ was decapitated or ringed at an upper position with the auxin transport inhibitor N-1-naphthylphthalamic acid (NPA) mixed with lanolin. The transport of apically applied
