JasperJasper is a very popular visitor in the hospitals and care homes around Portland. A therapy dog for most of his life, Jasper has learned how to work a room and, like any performer, he has a knack for finding the most appreciative members of the audience. “He’s very intuitive,” says his owner, Ilene Agosto. “I let him go where he wants and choose who to greet.”

As a Great Pyrenees weighing 120 pounds, Jasper is not a typical lap dog, but he’s happy to oblige if someone wants to snuggle. On a recent visit to an Alzheimer’s facility, Jasper immediately recognized a kindred spirit: He went over to the biggest man in the room and got acquainted. Then, much to the man’s delight, Jasper backed up and gently sat on his lap. ”It was love at first sight,” says Agosto.

Although the best skills he brings to his job are a gentle nature and friendly attitude, Jasper is most famous for his hats. He has dozens, including Jamaican dreadlocks, a propeller beanie and, of course, a nurses hat. All the staff at his regular stops look forward to seeing what he will wear next. “If I forget his hat, I have to stop and buy one,” laughs Agosto.

In May, Jasper was diagnosed with osteosarcoma (bone cancer) in his left fore limb. Canine osteosarcoma is an aggressive cancer and, untreated, dogs usually die within two months of diagnosis. “The gold standard for canine osteosarcoma treatment involves amputation and chemotherapy,” says Dr. Haley Leeper, canine oncology resident at OSU Veterinary Teaching Hospital (VTH). “However, we offer palliative options for owners who elect not to pursue amputation.”

Because Jasper is so big, and his cancer is in a front leg, Agosto chose to treat him for pain and quality of life only. “Dogs carry 60% of their weight in their forelimbs,” says Dr. Leeper. “A forelimb amputation puts stress on the remaining front leg which can lead to osteoarthritis and other joint disorders.”

Dr. Leeper, and canine oncologist Dr. Shay Bracha, are treating Jasper with pain medication, chemotherapy and Zoledronate, a bisphosphonate that improves bone density and prevents fracture. Now into his seventh month of treatment, Jasper is tolerating the chemotherapy and doing well, with no weight loss and no lameness in his front leg. Jasper continues to make therapy visits, and is living a normal dog life with his pal Moxie.

Jasper’s last visit to OSU for chemotherapy is coming up so Tammy Barr, the VTH client advocate, got him a special going away present: An orange cap with Benny the Beaver on the front and his name embroidered on the side. “He’s such a special dog,” she says. “He loves to get hugs from clients in our lobby, and he puts a smile on everyone’s face, even those that are so worried about their own pet. I thought he needed an OSU hat so his other friends would know that he goes to OSU and is a Beaver Believer!”

 

Dr. Morrie Craig has translated his research into a plan for using sheep to clean contaminated soil.
Dr. Morrie Craig has translated his research on rumen bacteria into a plan for using sheep to clean up soil.

The Iraqi invasion of Kuwait in 1991, and the ensuing Persian Gulf War, left behind half a million unexploded land mines. Today, Explosive Ordnance Disposal teams are still working to clear out those mines.

Less critical, but still a serious health concern, is the residue left from exploded ordnance. Soil across Kuwait is contaminated with TNT and other explosive compounds. If inhaled in dust, or ingested through ground water, TNT residue can cause dermatitis, kidney disease, anemia, and even cancer. Traditional soil cleaning methods like incineration are expensive and mar the environment. OSU Professor Morrie Craig has a better idea: Send out the sheep.

As a toxicologist in the College of Veterinary Medicine, Craig discovered that the multiple stomach chambers in a sheep contain bacteria that break down alkaloid toxins in plants. This makes it possible for them to eat all kinds of nasty weeds that make other animals sick.

When the U.S. military heard about his research, they suggested Craig test sheep bacteria on a synthetic alkaloid toxin: TNT. Used in the manufacture of bombs for the U.S. military since World War II, the military was looking for cost-effective ways to clean up TNT-contaminated sites in the U.S. and around the world.

In 2011, Craig and researchers from the U.S. Department of Agriculture fed sheep TNT for three weeks and found that it broke down in the sheep’s stomach so completely there was no trace of it in their feces. When coupled with Craig’s earlier research on the use of grasses to suck contaminants out of the soil, these new findings gave Craig a plan for bioremediation of explosives residue: Plant grass in contaminated areas then graze sheep on those fields.

CraigCamelAfter testing his plan on soil at a military base, Craig estimates a flock of 20 sheep can completely clear an acre of explosives residue in less than three years. Now he is working with the Kuwaiti government to help them adapt his discoveries to a plan that will work in their country. They are currently testing warm-season grasses for TNT uptake, and they are investigating the possibility of using camels as well as sheep. Funding for the projects comes from a tax on Iraqi oil as part of a United Nations settlement to compensate Kuwait for damage done by the Persian Gulf War.

In December, Dr. Craig will be the keynote speaker at an international seminar in Kuwait on The Environmental Impact of Explosive Remnants of War.

OSU’s International Veterinary Students Association made their annual trek to Nicaragua in August, creating a free clinic in the jungle for a rural community that has no veterinary care available. In just six days they treated 623 animals, providing spay and neuter surgery, dental care, disease treatment, and health education. Thirty-two veterinary students, four veterinarians, and three certified veterinary technicians volunteered their time to the mission, which relies on charitable donations for supplies and travel expenses.
