Study Indicates 50% Survival Rate in Mice After Fatal Radiation 

Exposure



ImmuneRegen BioSciences and Department of Defense Study Provides 

Further    Evidence that Homspera May Increase Survival Rate of 

Radiation Exposure 



SCOTTSDALE, Ariz., Aug. 26 /PRNewswire-FirstCall/ -- GPN Network, 

Inc. (OTC Bulletin Board: GPNW) today announced that its wholly owned 

subsidiary, ImmuneRegen BioSciences, Inc., a research and development 

biotechnology company, has completed its recent radiation-based 

research.  The results indicated a 50 percent survival rate of 

treated mice, which ImmuneRegen believes is attributable to its 

Homspera Treatment.  The recent study, which was done in 

collaboration with the Department of Defense (DoD), was designed to 

study the effects of the company's proprietary substance, Homspera, 

on mice after exposure to fatal doses of radiation.



The study, conducted at the University of Arizona by Dr. Mark Witten, 

PhD, co-founder and acting head researcher of ImmuneRegen 

BioSciences, Inc., was performed on 16 mice, four of which were 

controls.  Each mouse was given a single, fatal dose of radiation, 

then all non-control mice received an aerosol dose of Homspera, a 

proprietary manufactured form of the naturally occurring 

immunomodulator Substance P, for 35 days.  After 35 days of 

treatment, six of the original twelve mice survived the lethal 

radiation dose and currently do not appear to show any adverse signs 

or side effects from the injury or the treatment.



This study was based on a similar previous study with a smaller 

sample group.  The results of that study indicated a 25 percent 

survival rate for those mice treated with Homspera which ImmuneRegen 

believes is attributable to its Homspera Treatment.  Based on the 

success of these studies, the company plans to continue with its 

research and move to larger animal groups, such as monkeys.



"We have been researching the effects of Homspera on radiation 

exposure for some time," states Michael K. Wilhelm, CEO of 

ImmuneRegen BioSciences, Inc.  "This latest research study and its 

corresponding results show great potential for Homspera in our future 

treatment for radiation exposure."

Japan to join treaty on nuclear waste



TOKYO, Aug. 26 (Kyodo) - The Japanese government decided Tuesday to 

join Nov. 24 a treaty intended to ensure the safety of nuclear waste 

management, government officials said.



The Diet has already approved the Joint Convention on the Safety of 

Spent Fuel Management and on the Safety of Radioactive Waste 

Management.



The treaty, which went into effect in June 2001 with the membership 

of 25 countries, had 31 members as of Aug. 5.



In line with the treaty, Japan will soon submit a report to the 

International Atomic Energy Agency on the amount of used spent 

nuclear fuel and radioactive waste and the facilities used to contain 

it.

Iowa Senators Bash Army's Cleanup Delay



IOWA CITY, Iowa (AP) - Sens. Tom Harkin and Charles Grassley are 

urging the Army to press ahead with its cleanup of dangerous 

contaminants at an ammunition plant in southeastern Iowa.



In a letter Monday to acting Army Secretary Les Brownlee, Harkin 

criticized the Army for delaying the removal of chemical and 

radioactive materials at the Iowa Army Ammunition Plant in 

Middletown.



``The workers at IAAP and their families devoted their lives to our 

national security. It is past time that we devote ourselves to their 

safety,'' Harkin, a Democrat, wrote.



Grassley, a Republican, said while he understands the need to adjust 

the cleanup schedule, significant delays are unacceptable.



``Iowans need to know that this won't continue to drag on with no end 

in sight,'' Grassley said.



>From the 1940s to 1970s, the 19,000-acre plant was one of several 

nationwide that assembled and tested nuclear weapons. It continues to 

make missiles and other ordnance for the Army.



After explosives residue, spent uranium and other hazardous materials 

were found, the Environmental Protection Agency designated a portion 

of the site as a Superfund site.



The Army, with assistance and oversight from the EPA, is responsible 

for developing and carrying out the cleanup that was initially slated 

for completion in 2014.



Tensions between the two agencies have increased amid negotiations 

over the latest cleanup plans, which suggest pushing back deadlines. 

Army correspondence to the EPA states: ``Dates for most documents and 

fieldwork will be extended many years,'' according to Harkin's 

letter.



The EPA and the Iowa senators are pushing for a faster timeline.



Army spokeswoman Cynthia Smith did not respond to Harkin's letter, 

citing a department policy not to comment on correspondence between 

senior Army officials and members of Congress.



Harkin complained that a new Army request for additional study on 

chemicals contaminating ground water outside plant boundaries is 

unfair to nearby property owners. Several residents have been forced 

to give up using water from their wells.

U.N. Finds Uranium at Iran Nuclear Plant



VIENNA, Austria (AP) - U.N. inspectors found traces of highly 

enriched, weapons-grade uranium at an Iranian nuclear facility, a 

report by the U.N. nuclear agency says. Iran said Tuesday the traces 

came with equipment purchased abroad decades ago.



The find heightened concerns that Tehran may be running a secret 

nuclear weapons program.



Agency inspectors found ``particles'' of highly enriched uranium that 

could be used in a weapons program at the facility at Natanz, said 

the report prepared for a meeting of the U.N. agency's board Sept. 8 

in Vienna. Contents of the report were made known to The Associated 

Press by diplomats who requested anonymity.



The United States has accused Iran of developing a clandestine 

nuclear weapons program, violating the Nuclear Nonproliferation 

Treaty barring the spread of atomic weapons.



Iran has denied the allegations, insisting its programs are devoted 

only to generating electricity.



Ali-Akbar Salehi, Tehran's ambassador to the IAEA, said the equipment 

was ``contaminated'' with enriched uranium before it was purchased by 

Iran.



Salehi told AP the equipment in question was ``brought many years ago 

from intermediaries'' and so it was impossible to name the countries 

of origin.



Separately, Salehi also said Iran was ready to negotiate an IAEA 

request that it sign an additional agreement throwing open its 

nuclear programs to more intrusive inspections.



Salehi said the offer, made Monday, indicates ``for the first time 

... that the government of Iran is ready to enter negotiations into 

the additional protocol.''



He said talks would likely begin after two IAEA meetings next month; 

one on Sept. 8 by the agency's board of governors on the Iran report 

and another the week after when the full IAEA assembly convenes.



IAEA spokesman Mark Gwozdecky called Iran's overture ``a positive 

step.''



Suspicion about Iran's nuclear program prompted Mohamed ElBaradei, 

the director-general of the Vienna-based IAEA, to tour Iran's nuclear 

facilities in February. The visit was intended to ensure that Iran's 

nuclear program was limited to peaceful, civilian purposes and that 

the facilities were safe.



ElBaradei's tour included a visit to the incomplete nuclear plant in 

Natanz, about 320 miles south of Tehran. At the time, diplomats said 

he was taken aback by the advanced stage of a project using hundreds 

of centrifuges to enrich uranium.



ElBaradei, in advance comments to be published Thursday by the German 

news magazine Stern, said the traces were found on the centrifuges at 

Natanz, adding ``This worries us greatly.''



Salehi, Iran's chief IAEA delegate, said the centrifuges in question 

were being used only to produce low enriched uranium used as fuel for 

power plants.



Gwozdecky said the agency's inspectors had visited Iran five times 

since June.



``In particular, we have visited a number of new sites, have the 

results of previously taken environmental samples and taken many more 

new samples, and are in receipt of much new information from the 

Iranian authorities,'' he said.



Analyzing the new material would take ``weeks or months,'' he added.



In July, ElBaradei pressed Iran for ``substantial progress without 

delay'' in clarifying aspects of its nuclear program and in signing 

an agreement that would let U.N. inspectors conduct in-depth and 

comprehensive checks of Tehran's nuclear facilities.



At that time, he denied reports that agency inspectors found enriched 

uranium in samples taken recently in Iran, calling it ``pure 

speculation at this stage.''



Iran is building, with Russian help, its first nuclear reactor at 

Bushehr, on the shore of the Persian Gulf. It has a capacity of 1,000 

megawatts and should be completed next year.



Iran's second nuclear reactor will have a capacity of 1,000 megawatts 

and the government is beginning feasibility studies for a 5,000 

megawatt reactor, the official Islamic Republic News Agency reported 

this month.

Childhood cancer survival comes at cost - US study



By Maggie Fox



WASHINGTON, Aug 26 (Reuters) - Most U.S. children diagnosed with 

cancer now survive, but life comes at a price -- later cancers, heart 

disease and learning disorders, according to a report issued on 

Tuesday.



Parents, doctors and the cancer survivors themselves need a clear set 

of guidelines so they know what to look for as the years pass, an 

expert committee at the Institute of Medicine said in the report.



"Success in treating disease has been tempered by the knowledge that 

the cure has often came at a price, which may not be manifest until 

many years after completion of therapy," the report reads.



"As many as two-thirds of childhood cancer survivors are likely to 

experience at least one late effect, with perhaps one-fourth of 

survivors experiencing a late effect that is severe or life 

threatening."



The Institute of Medicine, one of the National Academies of Sciences, 

advises the federal government on matters of health and medicine.



"What happens is for several reasons kids are not followed properly 

in many cases after they complete their therapy," Dr. Joseph Simone, 

a retired pediatric oncologist who chaired the panel, said in a 

telephone interview.



"Once the chance of recurrence has dissipated, perhaps the family 

doesn't want to go back to an environment that has bad memories, 

children get to be adolescents and say 'I don't want to go back to 

that children's place', families move ... so there is no structure 

naturally for them to go to," added Simone.



"And we can't expect primary care doctors to take on this 

responsibility without some form of guideline, really some form of 

road map to follow."



The panel called on the National Cancer Institute to put together the 

guidelines so they could be widely available.



RISKS DEPEND ON THE CURE



They could be long and complex, because a patient's health risks 

depend on what kind of cancer they had as children and what treatment 

they got.



For instance, leukemia survivors risk learning disabilities, heart 

problems, hepatitis C from blood transfusions, obesity and 

osteoporosis.



Brain cancer survivors need to be watched for learning disabilities 

or other neurologic effects, hearing loss, kidney damage, infertility 

and vision problems.



"We have to consider cancer in children, the ones who survive, a 

chronic disease now," Simone said.



As of 1997, there were 270,000 survivors of childhood cancer of all 

ages in the United States.



"This translates to about 1 in 640 adults between ages 20 to 39 

years," the report reads.



Pediatric cancer once was a death sentence but treatment methods have 

brought the overall survival rate up to 78 percent. An estimated 

12,400 children and adolescents under age 20 were diagnosed with 

cancer in 2000, the report said, and 2,300 died of cancer the same 

year.



"Most patients who survive cancer have been exposed to combinations 

of two or three of the mainstays of cancer treatment: chemotherapy, 

radiation therapy, and surgery," the report said.



These treatments can be harsh and while they kill the cancer, they 

damage healthy cells, too -- leading to long-term consequences.



Simone said he was struck by how many parents of children with cancer 

did not realize their children would need specialized follow-up care.



"As many as 50 to 60 percent of children with cancer are initially 

treated in specialized cancer centers, but only an estimated 40 to 45 

percent are receiving follow-up care in specialized clinics," the 

report said.
