Dr Lisa Komoreng’s research highlights traditional medicinal plant qualities used to deal with diseases like TB and elephantiasis.

The burden that diseases like tuberculosis (TB), lymphatic filariasis (elephantiasis), sexually transmitted infections (STIs), skin infections, and ear, nose and throat (ENT) infections bring to the country, mainly poverty-stricken communities, has prompted Dr Lisa Komoreng to focus her research on traditional medicinal plants.

 

South Africa, says Dr Komoreng, has the third highest number of reported cases and the fifth highest number of estimated prevalent cases, with the second highest burden of drug-resistant TB cases in the world amongst the 22 high-burden countries.

South Africa is burdened
by elephantiasis and treating
it remains a huge problem,
says Dr Lisa Komoreng.

 

“According to the Free State Provincial Strategic Plan (2012-2016), HIV and TB are the leading causes of death in the Province, with TB being the second most leading cause. Our country is also burdened by elephantiasis and treating it remains a huge problem. Patients are often turned away from some of the public hospitals, reasons being that there is no treatment in the country or that the disease needs specialist care. It with this in mind that my research focuses on providing treatment that is cheaper than western medicine, easily accessible, with fewer or no side effects,” she said.

 

“People suffering from elephantiasis are not only physically disabled, but they suffer mental, social and financial losses contributing to stigma and poverty. Some of the drugs used to treat the disease are ineffective against adult parasitic worms, which are the ones that cause the disease, and they also have side effects. Our research in dealing with these diseases enables us to work hand-in-hand with herbalists, traditional healers and people who have indigenous knowledge about the use of traditional medicine. We consult with them in order to acquire information about the medicinal plants that are used to treat and manage those diseases. Once they provide us with information, we collect the plant species together, which we subsequently take to the University herbarium for proper identification of their scientific names and to the laboratory for experiments,” she added.

 

Dr Komoreng is a Senior Lecturer in the Department of Plant Sciences at the Qwaqwa Campus. She has authored and co-authored over 15 research articles and has presented her research at various national and international conferences.  Her research team comprises of 5 MSc and 4 PhD students.

 

The Thuthuka NRF Rating Track (2015 – 2017 and 2018 – 2020) funds the research project on elephantiasis.

Different look for research in controlled circumstances at the UFS  

Research in controlled circumstances at the University of the Free State (UFS) turned a new page today with the inauguration of four modernised controlled environment cabinets of the Department of Soil, Crop and Climate Sciences.

“The controlled environment cabinets, which are situated next to the glass houses on the eastern side of the Agriculture Building on the Main Campus in Bloemfontein, were installed in the early 1980’s.  The cabinets, used for research purposes in controlled circumstances by the UFS for many years, became dysfunctional and needed to be repaired and put into use again,” said Prof Herman van Schalkwyk, Dean: Faculty of Natural and Agricultural Sciences at the UFS.

“The cabinets are used by the agronomics, horticulture and soil science divisions of the Department of Soil, Crop and Climate Sciences to control factors such as the temperature, the intensity and quality of light, synthesis and humidity.  This is done 24 hours a day, with hourly intervals,” said Prof Van Schalkwyk.

The cabinets are ideally suited to determine the joint and separate effects of these factors on the growth of plants.  The adaptability of plants to climate can also be investigated under controlled circumstances.  All of this leads to a better understanding of the growth and development process of plants, more specifically that of agricultural crops. 

“The effect of these environmental factors on the effectiveness of insect killers such as fungus killers, insecticide and weed killers can also be investigated and can help to explain the damage that is sometimes experienced, or even prevent the damage if the research is timeously,” said Prof Van Schalkwyk.

A new cabinet can cost between R2-3 million, depending on the degree of sophistication.  “Although controlled environment cabinets have been used for agricultural research for a long time, it has become costly to maintain them     and even more impossible to purchase new ones,” said Prof Van Schalkwyk.

According to Prof Van Schalkwyk the cabinets were re-built by die UFS Electronics and Mechanisation Division.  Some of the mechanisms were also replaced and computerised.   

“The re-building and mechanisation of the cabinets were funded by the faculty and because the work was done by our own staff, an amount of about R1 million was saved.  The maintenance costs will now be lower as the cabinets are specifically tailor made for our research needs,” said Prof Van Schalkwyk.

Where all monitoring was done manually in the past, the cabinets can now be controlled with a computer.  This programme was designed by Prof Koos Terblans from the UFS Department of Physics. 

According to Prof Van Schalkwyk the modernisation of the cabinets is part of the faculty’s larger strategy to get its instruments and apparatus up to world standards.  “With this project we have proved that we can find a solution for a problem ourselves and that there are ways to get old apparatus functional again,” said Prof Van Schalkwyk.
