(gcide) | digitalin \dig"i*ta`lin\, n. [Cf. F. digitaline.]
(a) (Medicine, Pharmacy) Any one of several extracts of
foxglove (Digitalis), as the "French extract," the
"German extract," etc., which differ among themselves
in composition and properties. Both Digitalis lanata
and Digitalis purpurea have been used to prepare
such extracts.
(b) (Chem.) the distinctive chemical substance, a steroid
glycoside, which is the essential ingredient of the
extracts of foxglove. It is a white, crystalline
substance (C36H56O14), and is a 3-substituted
diglucoside of a steroid. It is a powerful cardiac
stimulant and is used as a cardiotonic for treatment
of certain heart conditions, such as congestive heart
failure. Chemically it is
(3[beta],5[beta],16[beta])-3-[6-Deoxy-4-O-[beta]-D-glucopyranosyl-3-O-methyl-[beta]-D-galactopyranosyl)oxy]-14,16-dihyroxy-card-20
(22)-enolide. The related compounds digitoxin and
digoxin are also extracted from the foxglove. The
class of steroid glycosides having cardiotonic
properties are refered to as the cardiac glycosides.

56 kbps
(foldoc) | 56 kbps
(56 kilobits per second) The data capacity of
a normal single channel digital telephone channel in North
America. The figure is derived from the bandwidth of 4 kHz
allocated for such a channel and the 16-bit encoding (4000
times 16 = 64000) used to change analogue signals to
digital, minus the 8000 bit/s used for signalling and
supervision.
At the end of 1997 there were two rival modem designs
capable of this rate: k56flex and US Robotics' X2. In
February 1998 the ITU proposed a 56kbps standard called
V.90, which is expected to be formally approved during
September 1998.
