Sawit Penawar Kanser Hati

Ketua Jabatan Biokimia Universiti Kebangsaan Malaysia (UKM), Prof Wan Zurinah Wan Ngah.

KELAPA SAWIT PENAWAR KENSER HATI

KANSER hati atau kanser hepar merupakan salah satu kanser yang paling sering ditemui dengan kadar 250,000 hingga sejuta pesakit setahun.

Berbanding negara Barat dan negara maju yang lain, Asia Timur serta Asia Tenggara mencatatkan jumlah pesakit tertinggi.

Situasi itu menjadikan usaha untuk mencari penawar kepada penyakit ini agak lesu kerana kajian lebih tertumpu ke arah mencari penyelesaian penyakit kanser yang lain seperti kanser payu dara, kanser tulang dan kanser kulit.

Bagaimanapun faktor itu memberikan kesedaran kepada Ketua Jabatan Biokimia Universiti Kebangsaan Malaysia (UKM), Prof. Wan Zurinah Wan Ngah untuk ‘bertapa’ dalam makmalnya selama lapan tahun bagi mencari penawar kepada penyakit kanser hati yang menjadi masalah besar kepada masyarakat Asia.

Hasil usaha keras selama lapan tahun itu akhirnya membuahkan kejayaan apabila beliau berjaya membuktikan sigma tokotrienol yang terdapat dalam vitamin E dalam minyak kelapa sawit (‘palm vitee) mampu mengurangkan proses keterukan barah hati.

Ia merupakan pertemuan pertama seumpamanya di negara ini.

Pertemuan ini dibentangkan semasa menyampaikan syarahan perdana sempena pelantikan ke jawatan profesor bertajuk ‘Kesan Perlindungan Vitamin E Kelapa Sawit Ke Atas Kanser Hepar’ di Kuala Lumpur, baru-baru ini.

Sigma tokotrienol merupakan satu daripada lapan jenis vitamin E. Jenis vitamin E ini mempunyai taburan yang luas dalam tumbuhan umum, tetapi kurang dalam minyak sayuran kecuali minyak kelapa sawit.

Justeru itulah, kajian di makmal ini ditumpukan kepada sigma tokotrienol (sejenis tokotrienol yang terbanyak dalam kelapa sawit) dan perbandingan juga dilakukan dengan sejenis lagi vitamin E yang dikenali sebagai alfa tokoferol.

Kajian ke atas vitamin E dan kanser telah banyak dilakukan dengan menggunakan model haiwan dan kajian epidemiologi.

Dalam konteks ini, pelbagai jenis kanser telah dikaji termasuk kanser oral, gaster, kolon, pankreas, hati, kulit dan payu dara.

Bagaimanapun, sebelum ini, kajian yang dilakukan adalah menggunakan alfa tokoferol sebagai sumber vitamin E.

Di Institut Penyelidikan Minyak Kelapa Sawit Malaysia (PORIM) sigma tokotrienol dikenal pasti sebagai sumber vitamin E untuk menghalang pembentukan sel barah payu dara.

Dalam melengkapkan kajian, Prof. Wan Zurinah menggunakan dua kaedah kajian praklinikal digunakan iaitu ‘in vitro’ dan ‘in vivo’.

Kajian ‘in vitro’ melibatkan kajian luaran di mana keberkesanan sigma tokotrienol terhadap sel kanser hati diuji dalam bekas kultur.

Kaedah ‘in vivo’ pula melibatkan penyuntikan sel barah ke dalam haiwan kajian iaitu tikus dan kemudiannya diberikan suplimen sigma tokotrienol.

Hasil kajian mendapati dengan dos rendah 30 mg/kg diet, alfa tokotrienol dapat mengurangkan keterukan proses keterukan barah hati dan lebih berkesan lagi jika suplimentasi dimulakan awal iaitu serentak atau empat minggu selepas barah dikesan.

Jika pembentukan kanser telah berkembang, pengambilan vitamin E ini kurang memberi kesan perlindungan. Bagaimanapun kesan perlindungan akan lebih ketara apabila pengambilan vitamin diteruskan sehingga sembilan bulan.

Menurut Prof. Wan Zurinah, hasil daripada penemuan ini telah membuahkan kepada penyelidikan-penyelidikan lain yang berkaitan.

Antaranya menurut beliau ialah melihat kesan Vitamin E ini ke atas manusia terutama mereka yang mempunyai risiko tinggi untuk menghadapi penyakit kanser hati seperti pesakit hepitatis B kronik.

Katanya, ini akan melibatkan kajian ‘Nutrition intervention trials’ yang selalunya melibatkan perbelanjaan yang sangat besar dan masa yang lama.

Di samping itu katanya, kajian lain yang boleh dilakukan ialah untuk melihat keperluan harian (RDA) vitamin E untuk orang normal dan pesakit.

Vitamin E Offers Powerful Protection Against Cataracts of the Eye

According to research, two-thirds of all Americans will have a cataract by age eighty-five. There is growing evidence that vitamin E may help to prevent this most common age-related vision problem. A cataract is a cloudy or opaque covering that grows over the lens of the eye, which can cause total or partial blindness. A cataract can distort vision by making objects look vague and fuzzy. If the cloudiness on the eye lens becomes so severe it hampers vision, the cataract must be surgically removed. Four million U.S. men and women have cataracts, and most people who have them are over the age of sixty. Cataracts are so commonplace in the United States that more than 10 percent of the Medicare budget is spent on cataract surgery.

In rare cases, a cataract may be caused by a genetic problem, but the overwhelming majority of cases are caused by cellular damage to the eye lens inflicted by exposure to ultraviolet and visible light. The lens of the eye is particularly susceptible to light-induced lipid and protein oxidation, a major factor in the majority of cases of cataracts. The lens contains proteins called crystallins, which, when damaged, can become irregular and refract light in the wrong way, thereby leading to cataract formation.

There are several reasons why I am optimistic that vitamin E may prove to be a useful tool in the prevention of cataracts of the eye. First, numerous animal studies have shown that vitamin E can arrest and reverse the development of cataracts symptoms and can protect the sensitive lens tissue from oxidative damage. Second, population studies have documented that people with low blood levels of antioxidants E, C, and carotenoids are more likely to develop cataracts than those with higher levels. The third, and perhaps the most persuasive, bit of evidence is a recent study that actually contrasted the self-reported consumption of supplements by 175 cataract-free patients over fifty-five to that of 175 patients of the same age group with cataracts. The cataract-free group used significantly more vitamins C and E than the group that already had developed cataracts. I think it is fair to say that even if vitamin E does not do the job alone, in combination with other network antioxidants it may offer powerful protection against cataracts of the eye.

Does Vitamin E Tocotrienols Prevent Breast Cancer?

Since one out of every eight women is destined to develop breast cancer, a tremendous amount of research has been undertaken to discover ways of preventing this common killer. One compound that has been extensively studied for its role in preventing breast cancer is tocotrieonls in vitamin E.

When reviewing all the published evidence, it does not appear that alpha-tocopherol vitamin E confers a protective effect against breast cancer. Yet studies show that women who consume foods high in other forms of vitamin E (tocotrienols) substantially reduce their risk of contracting breast cancer (by as much as 90%).

A cardinal feature of breast tumors are rapidly proliferating cells. Estrogen drugs promote hyper-proliferation and this is one reason why these drugs may quadruple the incidence of breast cancer.

Studies of breast cancer cells in culture indicate that tocotrienols have potent effects in inhibiting proliferation and inducing apoptosis (cancer cell death). These studies show that alpha-tocopherol does not have this same benefit.

Alpha tocopherol acetate is the most widespread supplement form of vitamin E, yet the evidence points to other forms of vitamin E as being responsible for the dramatic reduction in breast cancer incidence observed in great human studies.

The individual tocopherols and tocotrienols have different biological activities as they relate to their effects on cellular function. Gamma tocopherol, for instance, has demonstrated significant cancer prevention effects compared to alpha-tocopherol.

The potential anti-cancer effects of gamma tocopherol and the tocotrienols merits aggressive human clinical research to determine if women who supplement with these unique forms of vitamin E can reduce their risk of contracting breast cancer. Further research will be conducted on breast cancer patients to see if the addition of tocotrienols to tamoxifen improves long-term survival rates.

There is no compelling evidence that standard (alpha-tocopherol) vitamin E supplements reduce breast cancer incidence. While alpha-tocopherol has been shown to protect against a wide range of other diseases, it would appear that the tocotrienols are the ideal form of vitamin E to specifically reduce breast cancer risk
