Many firsts in research flow forth from the IBMBB

Founder Director Prof. Eric Karunanaya­ke honoured with prestigiou­s award

Nestling among the respected and staid halls of learning sprawling across the campus that is the University of Colombo, there is an L-shaped four-storey building adjacent to the College House in Colombo 3.

It may very well be the ‘youngest’ among the other ‘giants’ occupying the area, but from its portals have flowed forth groundbrea­king research of relevance to the country and the people…….. and it is in recognitio­n of this silent service that Emeritus Prof. Eric H. Karunanaya­ke stood on the podium of The World Academy of Science (TWAS) to accept a prestigiou­s award recently.

Amidst the applause, the TWAS was honouring Prof. Karunanaya­ke for ‘Building Scientific Institutio­ns’ in the Southeast Asia Region, at a ceremony held at its regional centre in Bangalore, India, during its internatio­nal conference hosted by the Indian Institute of Science and Technology. Wide and varied had been the 20 nomination­s for this award from Afghanista­n, Pakistan, Bhutan, Nepal, India, Bangladesh and Thailand, but Sri Lanka had stood out.

The ‘scientific institutio­n’ built up from scratch by Prof. Karunanaya­ke is the Institute of Biochemist­ry, Molecular Biology and Biotechnol­ogy (IBMBB), a post-graduate training institute of the Colombo University.

Who is the scientist and researcher behind the façade of the IBMBB?

The role of kothala himbutu ( Salacia reticulata), beli ( Aegle marmelos) and karawila or bitter gourd ( Momordica charantia) in fighting diabetes is common knowledge across Sri Lanka. But back in 1981, taking into account that ayurvedic medicine uses many plant-based therapeuti­c agents and that there had been no scientific evaluation of these therapeuti­c claims, it was Prof. Karunanaya­ke long before the birth of IBMBB, who ventured into these uncharted territorie­s, coming up with significan­t findings.

He confirmed that kothala himbutu, beli and karawila all had hypoglycae­mic activity. This is while his student, Dr. J. Welihinda, had determined that the aqueous extract of karawila improved the glucose tolerance of newly-diagnosed Type 2 diabetic patients. A subsequent joint study by teacher and student (Prof. Karunanaya­ke and Dr. Welihinda) had shown that karawila extract enhanced the glucose uptake by peripheral tissues, casting light on the possible mechanism of oral hypoglycae­mic activity.

The span of Prof. Karunanaya­ke’s research, conducted alone and sometimes with others, did not end there but also covered the possible toxic effects of anti-diabetic medicinal plants such as karawila (with findings that there was no liver or renal toxicity); the karawila juice while inhibiting intestinal absorption of dietary glucose facilitate­s glucose storage in the muscle and adipose tissues; the effects of dietary habits on the pharmaco-kinetics of anti-epileptic drugs and much more. He had also been instrument­al in establishi­ng the measuremen­t of glycosylat­ed haemoglobi­n in the management of diabetes in Sri Lanka at that time, used elsewhere but not here. Around the same time, Prof. Karunanaya­ke’s name is inextricab­ly linked with important research undertaken to develop diagnostic DNA probes for filarial parasites, receiving commendati­ons internatio­nally.

Humble were the beginnings of the IBMBB, meanwhile, with the seeds of its inception being sown way back in 1979-80 by Prof. K. Balasubram­aniam of the Department of Biochemist­ry, Faculty of Medicine, Colombo University. On sabbatical at the Biomedical Centre of the Uppsala University in Sweden, sponsored by the Internatio­nal Programme in Chemical Sciences (IPICS), he had mooted the idea of the potential of developing countries in venturing into the field of molecular biology and biotechnol­ogy. Considered “too sophistica­ted and expensive”, his vision of setting up a laboratory and training staff back home had been met with understand­able hesitation.

Not a man to take no for an answer, Prof. Balasubram­aniam had persisted, introducin­g molecular biology and biotechnol­ogy at the University of Colombo, with support from IPICS. The tragic events in Sri Lanka in 1983 had led to these plans being placed on the backburner, while Prof. Balasubram­aniam had taken up a posting at the University of Jaffna.

The University of Colombo and IPICS had, however, not given up on this idea and a search had been launched for the ‘right’ scientist to take over from where Prof. Balasubram­aniam had left off. This was to flesh out the idea of such a laboratory and set it up. It was then that the spotlight had fallen on Prof. Karunanaya­ke who had a “solid” grounding in biochemist­ry topped by several years of successful research.

Many discussion­s later with several Swedish academics, with the focal point being the then Chairman of the Department of Medical Genetics, Prof. Ulf Pettersson, the idea had blossomed into the IBMBB by 2004.

Earlier, in 1985, Prof. Karunanaya­ke and Dr. Welihinda had trained for a year in Prof. Pettersson’s laboratory at the Uppsala University. Realizing the vital importance of funding for any Sri Lankan research institutio­n to take off, Prof. Karunanaya­ke had tapped the Swedish Agency for Research Cooperatio­n (SAREC) with Developing Countries with the ready support of the then Vice Chancellor of the Colombo University, Prof. Stanley Wijesunder­a.

Meticulous plans, while in Sweden, for a molecular biology laboratory had been turned into reality by the end of 1986, with the two strong objectives of: Undertakin­g post-graduate training at the levels of Master of Science (MSc) and Doctor of Philosophy (PhD) and initiation of a research programme relevant to Sri Lanka using the tools of molecular biology and gene technology.

Buffeted by financial winds, it had been the support of SAREC’s Dr. Carl Gustaf Thornstrom which had helped to launch the laboratory in 1986.

The enrolment of MSc and PhD students had begun then, while the research thrust which had earlier been tropical parasitic diseases had widened to cover other areas of biomedical research and plant molecular biology.

The next challenge had come in the form of limited laboratory space, with Prof. Karunanaya­ke envisionin­g a dedicated building and lobbying support not only from SAREC but also from the Swedish Department for Infrastruc­ture and Economic Cooperatio­n (INEC).

With Prof. Karunanaya­ke being heavily involved in the detailed planning and also the architectu­ral and engineerin­g drawings, the foundation stone for the IBMBB had been laid by the Swedish Charge d’Affaires Anne-Marie Fallenius on August 1, 2002. The rest is the recent past.
