Why Isolated Silver? |
 We
originally coined the term "electrically isolated silver" to
help distinquish between different types of silver products on the
market. Read our article on EIS
- electrically isolated 'colloidal' silver and discover
why we feel classifying isolated silver provides a very important distinction.
Electrically Isolated Silver, in formulations
that include a highly ionic isolated silver content or a highly particulate
content
( picoscalar ), has not only proven to be more effective by direct
in-vitro
analysis
compared to any stabilized silver compound, but EIS formulations are
known to maintain the unique electromagnetic "silver signature" associated
with the pure element silver.

Medical Grade Silver Products & Laboratory Grade
Colloidal Silver Silverlon - Argentum Medical LLC, Dr. Bart Flick: FDA
Approved Wound Care Dressings Silverlon wound care dressings, FDA approved, are made
by impregnating extremely minute particles of silver to polymeric substrates
( which comprise the actual dressing ). Silverlon works by slowly releasing
silver ions into the tissues at the treatment site. The constant flow
of bioactive silver is responsible for Silverlon's amazing antimicrobial
properties. Silverlon

Silvadene - Marion Laboratories: FDA Approved Silver Sulfadiazine
Cream
Silvadene is an FDA approved topical cream used
in over 70% of hospitals in the United States to prevent bacterial
infections at burn sites, improve tissue healing, reduce scarring,
and is often prescribed as a topical treatment for skin graft donor
sites. This silver-rich cream ( a chemically produced silver salt
compound ) is FDA approved as a topical antifungal and antibacterial
for external use, and available on with a prescription. Silvadene
has been proven effective against both gram-positive and gram-negative
bacteria, including resistant strains.
Laboratory testing has demonstrated that Silvadene derives its antimicrobial
properties from direct action on cell membranes and cell walls. One
gram of Silver Sulfadiazine contains 10 milligrams of silver.
Silver Sulfadiazine was developed by Dr. Carl Moyer and Dr. Margraf
under a grant obtained by Dr. Moyer, former chairman of Washington
University's Department of Surgery.
Axenohl Silver Citrate Disinfectants: PURE Bioscience: EPA Registered
Technical Grade
PURE Bioscience, a NASDAQ traded company, developed and patented
a silver citrate molecule, and markets products generally ranging
from 30 PPM to 2400 PPM. Axenohl surface disinfectant products are
sold to control bacteria, mildew and fugus, and are marketed out
of Costa Rica.
Axenohl Pro Disinfectant, 2400 PPM, has been documented to kill
residual bacteria and virii 36 hours after a single application (
dilution 1:128 ).
Most of Axenohl products are currently not approved for industrial
or clinical use in the United States. However, recent approval by
the EPA for "Critical Care" ( a commercial disinfectant-fungicide-virucide
), marketed by EnvirOx, L.L.C. of Danville, Illinois, contains Axen
30, and has resulted in official approved uses in some US States.
PURE Bioscience, NASDAQ traded, has shared recent plans to sell
their water purification technology and persue broader markets with
their Axenohl product line, including seeking FDA approval through
a partnership with Therapeutics, Inc., based out of La Jolla, California.

Sistecam Laboratories Innovative
Medical Services AgION - Antimicrobial Powder Coating: Steel Coated with
Silver & Zeolite
AgION combines two key ingredients, silver ions and
zeolite ( a clay ). The silver ions are responsible for the active
antimicrobial properties, while the zeolite clay acts as a delivery
mechanism, an ion pump, that delivers the silver ions into
the environment in the presence of even a minute amount of moisture.
AgION is registered with the EPA ( for HVAC systems
), with the FDA ( for use as an additive in food contact polymers
), and the National Sanitation Foundation has certified AgION as
safe and acceptable for product zone and food zone applications.
AgION is being used at The City of Hope's Helford Clinical
Research Hospital, in Duarte, California, which is one of the most
advanced state-of-the-art research hospitals in the United States,
and houses the largest bone marrow transplant facility in the country
( the facility is scheduled for occupancy in 2004 ).

Silver Impregnated Urinary Bladder Catheters
The use of silver to control infections in-vivo has
been used in Europe at least since the mid 1990's. The use of silver
coated catheters was shown to be both cost-effective and successful,
according to a study done by Trenton Nauser, MD(*); Marcia Gilliland,
RN; Timothy Williamson, MD and Steven Q Simpson, MD. Pulmonary Diseases
and Critical Care Medicine and Infection Prevention & Control,
Kansas University Medical Center, Kansas City, KS.
"During the control period, there were 15,935
inpatient days, compared with 16,089 during the study period. During
the control period 29 patients experienced 33 infections that met
criteria for CUTI. During the study period 18 patients experienced
22 infections. Institution of the silver impregnated catheter was
associated with a 32% reduction in CUTI rate (1.37 vs. 2.07 per
1000 inpatient days, p [is less than] 0.001). Based upon our usage
data for indwelling bladder catheters, we calculated an annual
acquisition cost increase of $59,586. Using CDC data giving the
average cost of nosocomial UTI, we calculated that annual treatment
costs for CUTI will be reduced by $94,368. The institution should
save $34,782 in annual overall costs by continuing to use the silver
impregnated catheter."
More advanced technologies are available at this time,
including silver impregnated catheters that release silver ions by
electrolysis via a small electrical current ( very similiar to processes
used to make colloidal silver ).
