Abstract. Monosodium glutamate (MSG) is chemical compound that when it is used excessively it can cause various side effects such as hypercholesterolemia. Hypercholesterolemia will result in coronary heart disease (CHD), which is a disease causing death. The aim of study was assessing the effect of almond nut/ Prunus dulcis extract against total cholesterol level in mice that given MSG. This study was randomized post test controlled group design. The sample consisted of 30 mice (Mus musculus L. Strain DDW) that were divided into three groups: control group, treatment group 1 and treatment group 2. The plasma total cholesterol of mice was measured by the method of CHOD with spectrophotometer whose wave length 500nm. Data obtained was analysed by SPSS program version 16. The mean total cholesterol level in mice that treated with Prunus dulcis extraction after 4 weeks experiment was 130.37mg/dl. It were highest compared to the other groups. One way anova showed the significance value was p=0.44), means, there was no difference of total cholesterol level between control and treatment groups 1 and 2. There was no effect of Prunus dulcis extract against total cholesterol level in mice that given monosodium glutamate.
Lunasia amara telah digunakan dalam perubatan tradisi untuk merawat diabetes mellitus. L. amara dilaporkan mampu meningkatkan kesuburan tikus jantan normal pada dos 60 mg/kg berat tubuh. Kajian ini dijalankan untuk menentukan potensi ekstrak akuas batang L. amara sebagai agen anti-hiperglisemia dan keupayaannya mempertingkatkan parameter kesuburan tikus jantan teraruh-diabetes. Tikus teraruh-diabetes dibahagikan kepada enam kumpulan (n=5), masingmasing menerima perlakuan secara suap paksa ekstrak akuas L. amara (dos 60, 120, 250 dan 500 mg/kg berat tubuh), 500 mg/kg berat tubuh metformin dan air suling setiap hari selama tujuh hari. Manakala, kumpulan ke-tujuh merupakan kawalan normal (n=5) tanpa aruhan diabetes yang menerima perlakuan air suling (1 mL/tikus). Berdasarkan hasil kajian, dos anti-hiperglisemia yang berkesan iaitu 250 dan 500 mg/kg berat tubuh L. amara dipilih untuk melihat pengaruhnya ke atas kualiti sperma dan histologi testis tikus teraruh-diabetes. Hanya tikus teraruh-diabetes dengan perlakuan 500 mg/kg berat tubuh ekstrak L. amara digunakan untuk melihat taburan pengambilan 2-(N-(7-nitrobenz-2-oksa-1,3diazol-4-il)amino)-2-deoksiglukosa (2-NBDG) di dalam testis. Selepas 30 hari perlakuan, tikus teraruh-diabetes dengan perlakuan 250 dan 500 mg/kg berat tubuh L. amara didapati merencat kesemua parameter kesuburan jantan yang dikaji walaupun berkesan dalam menurunkan aras glukosa darah. Perlakuan dengan dos 500 mg/kg berat tubuh L. amara juga tidak berupaya menggalakkan pengambilan 2-NBDG ke dalam sel testis tikus teraruh-diabetes berbanding kumpulan kawalan. Ini menunjukkan mekanisme anti-hiperglisemia L. amara tidak melibatkan pembaikan fungsi insulin daripada segi pengambilan 2-NBDG ke dalam testis serta tidak mampu menyumbang kepada pembaikan parameter kesuburan tikus jantan teraruh-diabetes.
Potensi Afrodisiak Lunasia amara ke atas Tikus Jantan Teraruh Diabetes (Aphrodisiac Potential of Lunasia amara on Diabetic-Induced Male Rats) NOR-RAIDAH RAHMAT, AMIRA KAMALRUDIN, SHAZRUL FAZRY & MAHANEM MAT NOOR* ABSTRAK Diabetes melitus telah terbukti mengganggu penghasilan testosteron dan menyebabkan masalah libido dalam kalangan lelaki. Sehingga kini, tiada kajian mengenai potensi Lunasia amara dalam membaiki aktiviti seksual tikus jantan teraruh diabetes. Oleh itu, kajian ini dijalankan untuk mengenal pasti potensi afrodisiak L. amara ke atas tikus jantan teraruh diabetes. Empat kumpulan tikus teraruh diabetes masing-masing diberi perlakuan ekstrak L. amara (250 dan 500 mg/ kg berat tubuh), 500 mg/kg metformin dan air suling. Tikus kumpulan kawalan normal tanpa aruhan diabetes menerima perlakuan air suling. Perlakuan diberikan secara suap paksa selama 30 hari untuk melihat kesan L. amara ke atas status libido, aras testosteron serum, berat tubuh tikus, morfometri testis dan epididimis kauda serta aktiviti enzim antioksida testis tikus teraruh diabetes berbanding kawalan. Keputusan kajian menunjukkan berlaku penurunan libido, aras testosteron dan aktiviti khusus enzim antioksida (glutation peroksidase, katalase dan superoksida dismutase) testis tikus teraruh diabetes secara signifikan (p<0.05) pada kedua-dua dos tersebut berbanding kawalan normal. Sementara itu, perlakuan L. amara didapati tidak menjejaskan morfometri testis, epididimis kauda dan berat tubuh tikus yang menerima perlakuan L. amara berbanding kawalan normal. Kajian ini membuktikan bahawa ekstrak akuas batang L. amara pada dos 250 dan 500 mg/kg berat tubuh tidak berupaya memperbaiki aktiviti seksual tikus jantan teraruh diabetes. ABSTRACT Accumulating evidence shows that diabetes mellitus alters the production of testosterone and contributes to the reduction of libido in male. Formerly, no study has been conducted on the effect of Lunasia amara on sexual activity in diabeticinduced male rats. Therefore, present study looked into the aphrodisiac potential of L. amara on diabetic-induced male rats. Four groups of diabetic-induced male rats were given L. amara aqueous extract (250 and 500 mg/kg body weight), 500 mg/kg metformin and distilled water, respectively. A group of control rats was given distilled water. Treatments were given for 30 days to investigate the effect of L. amara aqueous extract on libido, serum testosterone level, body weight, morphometry of testis, cauda epididymis and antioxidant enzymes activity in diabetic-induced rats in comparison to control. The result showed diabetic-induced rats treated with both doses of L. amara extract exhibit significant reduction (p<0.05) in libido, testosterone level, testis antioxidant enzymes activity (glutathione peroxidase, catalase and superoxide dismutase) compared to control. On the other hand, the administration of L. amara did not affect body weight, morphometry of testis and cauda epididymis of diabetic-induced rats compared to normal control. This findings suggested that L. amara at ...
