Experimental farm
The Paradys Experimental Farm donated 428 bales of animal feed to farmers who lost veld in the Fauresmith and Tierpoort districts.

“I wish I had more to give.” These are the words of Johan Barnard, Junior Lecturer and manager on the Paradys Experimental Farm of the University of the Free State (UFS) after he donated the last of 428 bales of animal feed to a farmer from the Tierpoort area this morning (4 August 2021).

After large parts of the Paradys Experimental Farm were destroyed by veld fires three years ago and 24 famers came out to help fight the fire, Barnard believes in planting a surplus of food that would enable him to share with farmers in need. Last year, he donated bales of animal feed to farmers in the Hertzogville district whose veld was destroyed.

Sharing resources

More recently – less than a month ago – veld fires destroyed thousands of hectares of land in the Tierpoort and Fauresmith districts. Barnard, who helped to put out the fires and saw the destruction, decided to make the extra animal feed available to the farmers who needed feed for their animals.

Together with research and teaching and learning, the community is one of the university’s focus areas. “As a university, we are sharing our knowledge. The destruction brought about by the veld fires has created an opportunity where the university can also share its resources,” says Barnard.

When he made the decision to help, the feed was, however, still on the fields and had to be cut, processed, and baled. But where there is a will and a community that stand together, there is a way.

The farmers in the Koppieskraal district brought their tractors and machinery to cut, rake, and bale the sorghum and grass. BKB contributed fuel to cover the running costs of the tractors and machinery.

Once the animal feed was baled, Barnard contacted Jack Armour, operations manager at Free State Agriculture, who not only spread the word to farmers that animal feed was available, but also provided fuel to deliver the bales to the farms destroyed by fires. Since last week, volunteers have come to collect the animal feed and distribute it to the farmers.

Barnard, who believes it is difficult to put a price value on the animal feed provided by the university, says to the farmers who received it, the value of these bales is priceless.

A priceless gift

Besides the thousands of hectares of pasture destroyed during the raging fires, farmers also lost a significant number of sheep and cattle. When Leon Kruger, Lecturer in the Department of Animal Science, on the experimental farm, saw the devastation caused by the fires, he posted on Facebook that he was available to assist in treating the animals.

Together with two government veterinarians and a colleague from the Glen Agricultural College, Kruger drove hundreds of kilometres to farms in the south and southwestern Free State to help farmers treat animals affected by the fires.

He says they have treated more than 800 animals, including sheep and cattle. “We treated the animals one by one, administering antibiotics and pain medication, as well as ointment to the burned areas. This difficult ordeal was, however, a baptism of fire for all of us; we are not familiar with burn wounds. A friend in Australia helped to compile criteria to classify the different degrees of burn wounds and we treated the animals accordingly.”

“Seeing the suffering of the animals was one of the most difficult ordeals I had to experience,” states Kruger, who helped several farmers save their animals during this time where they have already lost so much.

Imagine that you have been diagnosed with bone cancer and only have six months to live. You are in a wheelchair because the pain in your legs is so immense that you can’t walk anymore – similar to a mechanism eating your bones from the inside.

You are lucky though, since you could be injected with a drug to control the pain so effective that you will be able to get out of the wheelchair within a day-and-a-half and be able to walk again. Real-life incidents like these provide intense job satisfaction to Prof André Roodt, Head of Inorganic Chemistry at the University of the Free State (UFS). The research, which is conducted by the Inorganic Group at the UFS, contributes greatly to the availability of pain therapy that does not involve drugs, but improves the quality of life for cancer patients.

The research conducted by the Inorganic Group under the leadership of Prof Roodt, plays a major role in the clever design of model medicines to better detect and treat cancer.

The Department of Chemistry is one of approximately 10 institutions worldwide that conducts research on chemical mechanisms to identify and control cancer. “The fact that we are able to cooperate with the Departments of Nuclear Medicine and Medical Physics at the UFS, the Animal Research Centre, and other collaborators in South Africa and abroad, but especially the methodology we utilise to conduct research (studying the chemical manner in which drugs are absorbed in cancer as well as the time involved), enhances the possibility of making a contribution to cancer research,” says Prof Roodt.

Technique to detect cancer spots on bone
According to the professor, there are various ways of detecting cancer in the body. Cancer can, inter alia, be identified by analysing blood, X-rays (external) or through an internal technique where the patient is injected with a radioactive isotope.

Prof Roodt explains: “The doctor suspects that the patient has bone cancer and injects the person with a drug consisting of an isotope (only emits X-rays and does no damage to tissue) that is connected to a phosphonate (similar to those used for osteoporosis). Once the drug is injected, the isotope (Technetium-99m) moves to the spot on the bone where the cancer is located. The gamma rays in the isotope illuminate the area and the doctor can see exactly where treatment should be applied. The Technetium-99m has the same intensity gamma rays as normal X-rays and therefore operates the same as an internal X-ray supply.” With this technique, the doctor can see where the cancer spots are within a few hours.

The same technique can be used to identify inactive parts of the brain in Alzheimer patients, as well as areas of the heart where there is no blood supply or where the heart muscle is dead.

Therapeutic irradiation of cancer
For the treatment of pain connected with cancer, the isotope Rhenium-186 is injected. Similar to the manner in which the Technetium-99m phosphonate compound is ingested into the body, the Rhenium-186 phosphonate travels to the cancer spots. Patients thus receive therapeutic irradiation – a technique known as palliative therapy, which is excellent for treating pain. A dosage of this therapy usually lasts for about two months.

The therapy is, however, patient specific. The dosages should correspond with the occurrence and size of cancer spots in the patient’s body. First, the location of the cancer will be determined by means of a technetium scan. After that, the size of the area where the cancer occurs has to be determined. The dosage for addressing total pain distribution will be calculated according to these results.

Technique to detect cancer spots on soft tissue
Another technique to detect cancer as spots on bone or in soft tissue and organs throughout the body is by utilising a different type of irradiation, a so-called PET isotope. The Fluor-18 isotope is currently used widely, and in Pretoria a machine called a cyclotron was produced by Dr Gerdus Kemp, who is a former PhD graduate from the Inorganic Research Group. The F-18 is then hidden within a glucose molecule and a patient will be injected with the drug after being tranquillised and after the metabolism has been lowered considerably. The glucose, which is the ‘food' that cancer needs to grow, will then travel directly to the cancer area and the specific area where the cancer is located will thus be traced and ‘illuminated’ by the Fluor-18, which emits its own 'X-rays'.

In the late 80s, Prof Roodt did his own postdoctoral study on this research in the US. He started collaborating with the Department of Nuclear Medicine at the UFS in the early 90s, when he initiated testing for this research.

Through their research of more than 15 years, the Inorganic Group in the Department of Chemistry has made a major contribution to cancer research. Research on mechanisms for the detection of cancer, by designing new clever chemical agents, and the chemical ways in which these agents are taken up in the body, especially contributes to the development in terms of cancer therapy and imaging, and has been used by a number of hospitals in South Africa.

The future holds great promise
Prof Roodt and his team are already working on a bilateral study between the UFS and Kenya. It involves the linking of radio isotopes, as mentioned above, to known natural products (such as rooibos tea), which possess anti-cancer qualities.
