ABSTRACT

Obesity has been considered as a great public health concern, that has spread in both economic and poor resources countries. This study aimed to investigate the effect of Elateriospermum tapos supplementation on the male offspring of female obesity-induced Sprague Dawley (SD) rats at weaning and adult age. A total of thirty (30) female and fifteen (15) male Sprague Dawley rats (N=45) were purchased for this study. Of the 30 female rats, six (n=6) were randomly selected as the control group (CG) and fed separately with male on standard chow diet, while the remaining rats (n=24) were fed on a high-fat diet for 5 weeks. The obese group were further randomly divided into 4 groups, positive control group (PG), orlistat treatment (DG) at 200 mg/kg, treatment 1 (TX1, 200 mg/kg E. tapos seed) and treatment 2 (TX2, 200 mg/kg E. tapos shell) for 6 weeks. One male pup from each dam was culled at weaning (postnatal day 21 (PND21)) and adulthood (12 weeks).  The liver, kidney, retroperitoneal white adipose tissue (RpWAT) and brown adipose tissue (BAT) were collected for histopathological study. Serum lipid profiles, liver enzyme activities and creatinine were measured. The bodyweight of male offspring from treatment 1 (MTX1) and 2 (MTX2) was significantly lower (P<0.05) compare to MNG group. The RpWAT weight in MTX1 and MTX2 for adult offspring also were significantly lower (P<0.05) compared to MPG. The histopathological examination of liver in MCG, MDG, MTX1, and MTX2 showed normal hepatocytes while the MPG group showed the presence of ballooning cell and hypertrophy of adipocytes was also observed in MPG group compared to another group’s rat. The E. tapos extracts from the shell have greater therapeutic potential on maternal obesity in short and long term treatment.

ABSTRAK

Keobesan merupakan masalah kesihatan yang besar dan telah merebak di seluruh dunia termasuk negara maju dan miskin. Tujuan kajian ini dijalankan adalah untuk mengkaji kesan suplemenElateriospermum tapos terhadap keobesan anak tikus jantan Sprague Dawley (SD) yang berusia 21 hari dan 12 minggu. Sebanyak tiga puluh (30) tikus betina dan lima belas (15) tikus jantan Sprague Dawley (N = 45) digunakan dalam kajian ini. Daripada 30 tikus betina, enam (n = 6) dipilih secara rawak sebagai kumpulan kawalan (CG) dan diberi makanan tikus secara berasingan, manakala tikus yang lain (n = 24) diberi makanan yang mengandungi tinggi lemak selama 5 minggu secara berterusan. Kumpulan tikus obes ini, seterusnya dibahagikan secara rawak kepada 4 kumpulan, kumpulan kawalan positif (PG), rawatan orlistat (DG) pada 200 mg/kg, rawatan 1 (TX1, 200 mg/kg bijiE. tapos) dan rawatan 2 (TX2, 200 mg/kg kulit bijiE. tapos) selama 6 minggu. Seekor tikus jantan dikorbankan pada hari ke 21 (PND21) dan juga pada usia 12 minggu (dewasa). Hati, ginjal, tisu adipos putih (RpWAT) dan tisu adipos coklat (BAT) dikumpulkan untuk kajian histopatologi. Profil lipid serum, enzim hati dan kreatinin diukur. Berat badan tikus jantan daripada kumpulan rawatan 1 (MTX1) dan 2 (MTX2) didapati jauh lebih rendah (P <0.05) berbanding dengan kumpulan MNG. Berat RpWAT daripada kumpulan MTX1 dan MTX2 adalah jauh lebih rendah (P <0.05) berbanding dengan kumpulan MPG. Pemeriksaan histopatologi hati di bawah mikroskop bagi MCG, MDG, MTX1 dan MTX2 menunjukkan sel hepatosit yang normal manakala kumpulan MPG mendedahkan adanya sel belon dan kehadiran hipertrofi adiposit juga diperhatikan pada MPG berbanding dengan tikus daripada kumpulan yang lain. Ekstrak E. tapos daripada cangkerang mempunyai potensi terapeutik yang lebih besar terhadap keobesan ibu dalam rawatan jangka masa pendek dan jangka masa panjang.
