The AA. reports the possibility to prepare special sugar mixtures at various degree of complexity (mono-di-oligo-polisaccharides). These have high solubility and neutral taste. These supply to athletes disposable amounts of glucose for muscular contraction during the play time.
Systemic absorption and sustained effects of two estrogen vaginal cream preparations (Premarin and Estrace) were measured in 29 postmenopausal women receiving daily applications. With both preparations, vaginal absorption of estrogens into the systemic circulation was rapid, efficient, and sustained. It is apparent that estrogen vaginal cream preparations, as widely used in clinical practice for their local effects on the vaginal mucosa, actually result in sustained high estrogen levels in the systemic circulation. The vaginal route shows promise when systemic estrogen therapy is indicated, but is dangerous when estrogen is contraindicated.
Intrathecal injection of a non-ionic contrast agent in the lumbar area of rabbits resulted in: (1) a rapid rise in blood iodine level with a maximum after 23-46 min; (2) low concentrations in cisterna magna during the observation period (24 h); and (3) complete or almost complete disappearance of visible contrast medium on the radiographs within 30 min. This indicates that after injection in the lumbar area of the rabbit most of the contrast medium absorption takes place from the lumbar area. Similar injections in cisterna magna showed the following: (1) a slow rise in blood level with a maximum after 150-275 min; (2) little or no disappeared of visible contrast medium on the radiographs within the first hour. This indicates that in the rabbit the absorption from the subarachnoid space of the spine takes place at different rates dependent on the level at which the injection has been made and the area of deposition of contrast medium.
