Primary intestinal lymphangiectasia is a congenital lymphatic disorder in which intestinal lymphatic channels are dilated and ruptured resulting in loss of protein, lipid, and lymphocyte into the intestine or peritoneum. As a result, hypoalbuminemia, generalized edema, diarrhea are clinically manifested. We report a case of primary intestinal lymphangiectasia with generalized edema which occurred in a 7-year old boy who was treated with lipid restriction diet with medium chain triglyceride oil supplement.

The effect of addition of fractionated milk fats on the composition and melting behavior of cocoa butter was investigated. High melting fraction (HMF) of milk fat fractions had the highest contents of long chain fatty acid $(C16{\sim}C18)$ and saturated fatty acid followed by medium melting fraction 1 (MMF1), medium melting fraction 2 (MMF2), anhydrous milk fat (AMF), and low melting fraction (LMF) in a decreasing order. MMF2 had the highest contents of the short chain fatty acid $(C4{\sim}C10)$ and medium chain fatty acid $(C12{\sim}C14)$ followed by AMF, HMF, MMF1, and LMF in a decreasing order. When the fractionated milk fats were added to cocoa butter, the long chain fatty acid contents increased with increasing the ratio of fractionated milk fats. The saturated fatty acid contents decreased only when the LMF was added. The higher content of long chain triglyceride and the lower contents of short chain triglyceride and medium chain triglyceride were obtained from the fractionated milk fat of higher melting point. When the fractionated milk fats were added to cocoa butter, long chain triglyceride contents decreased with increasing the ratio of the fractionated milk fats. The melting points of cocoa butter, AMF, HMF, MMF1, MMF2, LMF were $33.3^{\circ}C,\;31.2^{\circ}C,\;40.6^{\circ}C,\;37.4^{\circ}C,\;33.5^{\circ}C$, and $6.5^{\circ}C$, respectively. Cocoa butter had the highest content of solid fat followed by HMF, MMF1, MMF2, AMF, and LMF in a decreasing order. When the fractionated milk fat was added to cocoa butter at various temperatures, the solid fat content in the mixture of fractionated milk fat and cocoa butter decreased with increasing the ratio of fractionated milk fat. This results suggested that anhydrous milk fat and fractionated milk fats had a good compatibility with cocoa butter.

Triglyceride solid lipid with medium chain fatty acid, tricaprin (TC), was used as a core matrix of lipid nanoparticles (LN) to solubilize water-insoluble paclitaxel and enhance the stability of nanoparticles by immobilization of incorporated drug in the solid core during storage at low temperature. In the present study, TC-LN containing paclitaxel was prepared by hot melt homogenization method using TC as a core lipid and phospholipids as stabilizers. The particle size of TC-LN containing paclitaxel was less than 200 nm and its zeta potential was around -40 mV. Calorimetric analysis showed TC core could be solidified by freezing and thawing in the manufacturing process in which the hot dispersion should be prepared at elevated temperature and subsequently cooled to obtain solid lipid nanoparticles. The melting transition of TC core was observed at $27.5^{\circ}C$, which was lower than melting point of TC bulk. The particle size of TC-LN remained unchanged when kept at $4^{\circ}C$. Paclitaxel containing TC-LN showed comparable anticancer activity to the Cremophore ELbased paclitaxel formulation against human ovarian (OVCAR-3) and breast (MCF-7) cancer cell lines. Thus, lipid nanoparticles with medium chain solid lipid may have a potential as alternative delivery system for parenteral administration of paclitaxel.

One hundred and twenty weanling pigs in experiment 1 (Exp. 1) ($6.91{\pm}0.99kg$; 21 d of age) and Exp. 2 ($10.20{\pm}1.09kg$; 28 d of age) were used in two 42-d and 35-d experiments to evaluate the effect of medium-chain-triglyceride (MCT) on growth performance, apparent total tract digestibility (ATTD) of nutrients and blood profile. In both of Exp. 1 and Exp. 2, the same dietary treatments were utilized as follows : i) negative control (NC), ii) positive control (PC), NC+antibiotics (40 mg/kg Tiamulin, 110 mg/kg Tylosin, and 10 mg/kg Enramycin, iii) MCT3, NC+0.32% (phase 1, 2 and 3) MCT, and iv) MCT5, NC+0.55% (phase 1), 0.32% (phase 2 and 3) MCT. In Exp. 1, the pigs fed MCT5 diets had higher (p<0.05) ADG compared to NC treatment during the first 2 wk. From d 15 to 28, the ATTD of energy was improved (p<0.05) by MCT3 compared to the PC treatment. No effect has been observed on the blood profiles [red blood cell (RBC), white blood cell (WBC), immunoglobulin-G (IgG), lymphocyte concentration] measured in this study. In Exp. 2, the ADG were increased (p<0.05) by the MCT5 treatment than the PC treatment from d 0 to 14. Pigs fed PC treatment diet had lower ADFI (p<0.05) and better FCR (p<0.05) than NC treatment, whereas no differences were shown between MCT treatments and NC or PC treatment from d 15 to 35 and overall phase. The ATTD of DM and nitrogen were improved (p<0.05) by the effect of MCT5 related to the NC and PC treatment at the end of 2nd and 5th wk. The pigs fed MCT3 had higher (p<0.05) energy digestibility than PC treatment. No effects were seen in the blood profiles we measured (WBC, RBC, lymphocyte and immunoglobulin-G). In conclusion, the addition of MCT in the weanling pigs diet can improve the ADG and digestibility during the earlier period (first 2 wks), but had little effect on the blood characteristics.

Purpose: To investigate the impact of omega-3-enriched lipid emulsion (LE) on liver enzyme (aspartate transaminase [AST] and alanine aminotransferase [ALT]) and triglyceride (TG) levels of children undergoing gastrointestinal surgery. Methods: This experimental randomized controlled group pretest-posttest design study included 14 children who underwent gastrointestinal surgery due to duodenal atresia, jejunal atresia, esophageal atresia, and need for parenteral nutrition for a minimum of 3 days at RSUD Dr. Soetomo Surabaya between August 2018 and January 2019. These children were divided into two groups, those who received standard intravenous LE (medium-chain triglyceride [MCT]/long-chain triglyceride [LCT]) and those who received intravenous omega-3-enriched LE. Differences in AST, ALT, and TG levels were measured before surgery and 3 days after the administration of parenteral nutrition. Results: Liver enzyme and TG levels in each group did not differ significantly before versus 3 days after surgery. However, TG levels were significantly lower in the omega-3-enriched intravenous LE group (p=0.041) at 3 days after surgery, and statistically significant difference in changes in TG levels was noted at 3 days after surgery between MCT/LCT intravenous LE group and the omega-3-enriched intravenous LE group (p=0.008). Conclusion: The intravenous omega-3-enriched LE had a better TG-lowering effect than the MCT/LCT intravenous LE in children undergoing gastrointestinal surgery.

Medium- and long-chain triglyceride (MCT/LCT) propofol is widely used as an intravenous anesthetic, especially in the intensive care unit. The present study aimed to assess whether MCT/LCT propofol is safe in the hyperlipidemic population for long-term use. Free fatty acids (FFAs) were used to establish high-fat stimulation of HepG2 and Huh7 cells. Subsequently, these cells were treated with propofol at the concentration of 0, 4, or 8 ㎍/ml for 24 and 48 h. The results indicated that the cell viability was notably decreased when the cells were stimulated with 2 mmol/L FFAs and treated with 12 ㎍/ml MCT/LCT propofol. Accordingly, we chose 2 mmol/L FFAs along with 4 and 8 ㎍/ml MCT/LCT propofol for the subsequent experiments. Four and 8 ㎍/ml MCT/LCT propofol inhibited FFA-induced lipid accumulation in the cells and significantly reversed acetyl coenzyme A carboxylase (ACC) activity. In addition, MCT/LCT propofol not only significantly promoted the phosphorylation of AMPK and ACC, but also reversed the FFA-induced decreased phosphorylation of AMPK and ACC. In conclusion, MCT/LCT propofol reverses the negative effects caused by FFAs in HepG2 and Huh7 cells, indicating that MCT/LCT propofol might positively regulate lipid metabolism.

This study was designed to develop a microencapsulated, water-soluble isoflavone for application into milk and to examine the hypocholesterolemic effect of such a milk product in a rat diet. The coating material was medium-chain triglyceride (MCT) and the core material was watersoluble isoflavone. The microencapsulation efficiency was 70.2% when the ratio (w/w) of coating material to core material was 15:1. The isoflavone release from the microcapsules was 8% after 3-day storage at $4^{\circ}C$. In in vitro study, 4.0-9.3% of water-soluble isoflavone in simulated gastric fluid was released in the pH range of 2 to 5 after 60 min incubation; however, in simulated intestinal fluid at pH 8, 87.6% of isoflavone was released from the capsules after 40 min incubation time. In sensory analysis, the scores of bitterness, astringency, and off-taste in the encapsulated isoflavone-added milk were slightly, but not significantly, different from those in uncapsulated, isoflavone-added milk. In blood analysis, total cholesterol was significantly decreased in the isoflavone-added group compared with that in the control after 6-week feeding. Therefore, this study confirmed the acceptability of MCT as a coating material in the microencapsulation of water-soluble isoflavone for application into milk, although a slight adverse effect was found in terms of sensory attributes. In addition, blood total cholesterol was lowered in rats which had been fed a cholesterol-reduced and microencapsulated, isoflavoneadded milk for 6 weeks.

The objective of this study is to assess the impact of spray drying conditions on medium-chain triglyceride (MCT) loading, solubility, and release of an MCT-loaded solid self-emulsifying system in a water-insoluble oily substance. MCT-loaded solid self-emulsifying systems are prepared by spray drying with SDS and calcium silicate. The effects of inlet temperature (60, 80, or 100℃) and feed solution composition (0, 10, 50, 90, or 100% ethanol) on physicochemical properties of MCT-loaded solid self-emulsifying systems are studied. The inlet temperature significantly affects the water solubility of MCT. Moreover, the feed solution composition significantly affects water solubility, release rate, and MCT loading. The MCT-loaded solid self-emulsifying system obtained at 60℃ using 90% ethanol feed solution shows the best physicochemical properties among the synthesized products and exhibits better water solubility (4.43 ± 0.44 vs. 0 ㎍/mL) and release (94.4 ± 1.6 vs. 32.8 ± 7.4%, 60 min) than a commercial product. Furthermore, the MCT-loaded solid self-emulsifying system shows an excellent emulsion droplet size (approximately 230 nm).
