The hypoglycemic and hypolipidaemic effects of fenugreek seeds (Trigonella foenum graecum) are well established. Owing to the wide spread use of the seeds by healthy individuals and by diabetic patients we wanted to test whether the seeds can affect biological systems such as membrane transport function. In the present study fenugreek seed polyphenols were extracted and their effect on erythrocyte membrane-bound sodium-potassium adenosine triphosphatase $(Na^+/K^+-ATPase)$ activity was studied in vitro. Fenugreek seed polyphenols inhibited $Na^+/K^+-ATPase$ in erythrocyte membrane of diabetic and normal subjects. Maximum inhibition was observed at $100\;{\mu}l$ of extract containing 0.75 mM gallic acid equivalents. The uncoupling of membrane ATPases in vitro suggest that polyphenols from fenugreek seeds may possess a positive inotropic effect.

본 연구는 건강기능식품 호로파종자식이섬유 중 4-hydroxyL-isoleucine에 대한 분석법을 개발하는 연구이다. 최적분석 조건을 확립하기 위해 시료 채취량, 전처리 용매 및 이동상 용매 조건을 비교 검토하였으며, HPLC-PDA를 이용하여 시료 중의 4-hydroxy-L-isoleucine를 분석하였다. 분석 시 사용한 컬럼은 Capcell Pack UG120 C₁₈ (Shiseido, 4.6×250 mm, 5 ㎛)이며, 유도체 시약으로 OPA를 선정하였다. 확립된 시험법에 대해 특이성, 직선성, 검출한계, 정량한계, 정확성, 정밀성 등의 밸리데이션을 수행하였다. 5-100 ㎍/mL 농도에서 결정계수(R²) 0.999 이상으로 높은 직선성을 확인하였다. 또한, 회수율은 91.7-96.4%이었고, 정밀성은 0.5-1.1%의 상대표준편차(%RSD)를 확인하였다. 개발된 시험법은 호로파종자추출물 중 4-hydroxy-L-isoleucine 분석을 위한 시험법으로 활용되기에 적합한 것으로 판단된다.

Despite the reports on safety concerns regarding the relationship between aluminum salts and neurological and bone disease, many countries continue to use aluminum as phosphate binders among patients with renal failure. In search for a diet supplement that could reduce aluminum toxicity related to renal failure, we carried out this prospective animal study in which the fenugreek seeds were assessed for their effects on rats nephrotoxicity induced by aluminum chloride ($AlCl_3$). Oral $AlCl_3$ administration during 5 months (500 mg/kg bw i.g for one month then 1600 ppm via drinking water) led to plasma biochemical changes, an inhibition of alkaline phosphatase (ALP), a decrease of total antioxidant status (TAS), and an induction of lipid peroxidation (LPO) in the blood and brain, in addition to kidney atrophy and morphological alterations at the level of Bowman's capsule, the glomerulus and different sorts of tubules, reminiscent of some known kidney disease. The treatment with the whole fenugreek seed powder (FSP) (5% in the diet) during the last 2 months showed its effectiveness in restoring normal plasma values of urea, creatinine, ALP and glucose, as well as re-increasing the TAS, inhibiting LPO and alleviating histopathological changes in the injured kidneys. This study highlights the induced nephrotoxicicity, as well as the related toxicity in the brain and bone, by chronic oral ingestion of the aluminum salts. However, the maintenance of a diet supplemented with fenugreek seeds could offer protection for the kidney, bone and brain, at the same time.
