ABSTRACT There were no significant differences in the pharmacokinetics of micafungin and expression of hepatic multidrug resistance-associated protein 2 (ABCC2/Mrp2) between analbuminemic and Sprague-Dawley rats. Micafungin bound strongly to high-density lipoprotein (HDL) and moderately to gamma globulin. These results suggest that HDL and gamma globulin contribute to the pharmacokinetics of micafungin.

Lymph Duct

Recently, peripheral lymphatic vessels were found to transport high-density lipoprotein (HDL) from interstitial tissues to the blood circulation during reverse cholesterol transport. This function is thought to be critical to the clearance of cholesterol from atherosclerotic plaques. The role of organ-specific lymphatics in modulating HDL transport and composition is, however, incompletely understood. This study aimed to 1) determine the contribution of the lymphatics draining the intestine and liver (which are major sites of HDL synthesis) to total (thoracic) lymph HDL transport and 2) verify whether the HDLs in lymph are derived from specific organs and are modified during trafficking in lymph. The mesenteric, hepatic, or thoracic lymph duct was cannulated in nonfasted Sprague-Dawley rats, and lymph was collected over 5 h under anesthesia. Whole lymph and specific lymph lipoproteins (isolated by ultracentrifugation) were analyzed for protein and lipid composition. The majority of thoracic lymph fluid, protein, and lipid mass was sourced from the mesenteric, and to a lesser extent, hepatic lymph. Mesenteric and thoracic lymph were both rich in chylomicrons and very low-density lipoprotein, whereas hepatic lymph and plasma were HDL-rich. The protein and lipid mass in thoracic lymph HDL was mostly sourced from mesenteric lymph, whereas the cholesterol mass was equally sourced from mesenteric and hepatic lymph. HDLs were compositionally distinct across the lymph sources and plasma. The composition of HDL also appeared to be modified during passage from the mesenteric and hepatic to the thoracic lymph duct. Overall, this study demonstrates that the lipoproteins in lymph are organ specific in composition, and the intestine and liver appear to be the main source of HDL in the lymph. NEW & NOTEWORTHY High-density lipoprotein in lymph are organ-specific in composition and derive mostly from the intestine and liver. High-density lipoprotein also appears to be remodeled during transport through the lymphatics. These findings have implications to cardiometabolic diseases that involve perturbations in lipoprotein distribution and metabolism.

Protein content of winged bean is almost the same as soybean, but the beany flavor is more poweful than soybean. Therefore the protein of winged bean was isolated prior to use as raw material of yogurt. This research was aimed to determine the potency of  hypocholestrolemic activity of yogurt protein isolate of winged  bean through in vivo bioassay by using Sprague Dawley male rats. The treatments of the research were yogurt feed treatment with concentration of yogurt 0 (standard feed without yogurt as a control), 2, and 4 g yogurt/day as low and high concentration treatment respectively for 4th weeks after hypercholesterol feed  treatment for 1 week. The blood lipid profile of rats, including triglyceride, cholesterol total, High Density Lipoprotein (HDL), Low  Density Lipoprotein (LDL) cholesterol were analysed on the 2nd  and 4th weeks for the yogurt feed treatment while for before  yogurt feed treatment, the evaluation were based on the  adaptation phase and the 1st week for hypercholesterol phase.  The result of this research showed that the blood triglyceride,  cholesterol total, LDL increased, and the blood HDL decreased in hypercholesterol phase before yogurt feed treatment. The potency of hypocholestrolemic of yogurt from protein isolate of winged  bean was shown by the decreasing of blood triglyceride,  cholesterol total, LDL and increasing the HDL cholesterol after the yogurt feed treatment with low and high concentration. That  indicated that yogurt that was made of protein isolate of winged  bean could reduced cholesterol. ABSTRAKBiji kecipir memiliki kadar protein yang hampir sama dengan  kedelai, namun bau langunya lebih tajam daripada kedelai,  sehingga perlu diisolasi proteinnya sebelum digunakan sebagai  bahan baku yogurt. Tujuan penelitian ini adalah menentukan  potensi hipokolesterolemik yogurt isolat proteun biji kecipir  melalui uji biologis in vivo menggunakan tikus jantan Sprague Dawley. Perlakuan penelitian ini adalah perlakuan pakan yogurt  dengan konsentrasi 0 (pakan standar tanpa penambahan yogurt sebagai kontrol), 2, dan 4 g yogurt/hari berturut-turut sebagai  perlakuan konsentrasi rendah dan tinggi selama 4 minggu  perlakuan pakan yogurt sesudah pemberian pakan hiperkolesterol selama 1 minggu. Profil lipida darah tikus meliputi kadar trigliserida, total kolesterol, kolesterol High Density  Lipoprotein (HDL), dan Low Density Lipoprotein (LDL) dianalisis  pada minggu ke 2 dan 4 minggu selama perlakuan pakan yogurt  dan sebelum perlakuan pakan yogurt yaitu pada fase pemeliharaan adaptasi dan 1 minggu pada fase pemeliharan  hiperkolesterol. Hasil penelitian ini menunjukkan bahwa  trigliserida, total kolesterol, dan kolesterol LDL meningkat dan kolesterol HDL menurun selama fase pemberian pakan  hiperkolesterol sebelum perlakuan pakan yogurt. Potensi  hipokolesterol yogurt isolat protein biji kecipir ditunjukkan dengan penurunan trigliserida, total kolesterol, dan kolesterol LDL, serta peningkatan kolesterol HDL sesudah perlakuan pakan yogurt dengan konsentrasi rendah maupun tinggi. Hal tersebut mengindikasikan bahwa yogurt isolat protein biji kecipir mampu menurunkan kolesterol.
