Abstract
This work mainly studies the interfacial behaviors of scutellarin on a newly developed emulsion and establishes a three-phase distribution model. The results showed that the concentration of scutellarin could decrease the interfacial tension and the gel-liquid crystal phase transition temperature of phospholipids. By observing the micromorphology of the emulsion, it is inferred that the drug exists on the emulsion interface. The distribution of drugs in three phases at different pH was calculated. The results showed that when pH was in the range of 3.0-8.0, the content of scutellarin in the oil phase was less than 0.25%; when pH < 7.4, more than 88% of the drugs were on the interface; when pH > 7.4, the drugs were mainly distributed in the aqueous phase. Therefore, the behavior of emulsions (pH 6.0) in vitro and in vivo is mainly composed of the behavior of drugs on the interface. The study above can explain some properties of the emulsions after loading scutellarin. Including the decrease of particle size and stability constant Ke, the increase of zeta potential, and the decreased chemical stability after the pH value went higher.

Abstract
Research on intravenous emulsions has been ongoing for several decades, and their unique advantages bring many opportunities for insoluble drugs. However, emulsions cannot withstand freezing in practical applications because their quality is severely affected. In this study, we used coenzyme Q10 as a model drug to prepare emulsions. Monosialotetrahexosylganglioside (GM1) was used to modify the emulsion to solve the freeze-thaw intolerance problem. The particle size, sterilization and freeze-thaw stability were affected by the oil content, phospholipid content, drug loading and homogenization conditions, which showed significant effects on the preparation properties. Emulsions prepared with a high oil content (30%, W/V) withstood three freeze-thaw cycles when the GM1 content was 0.2%-1.0% (W/V). In addition, pharmacokinetic studies indicated that emulsions modified with high-density GM1 had a long circulation time. Compared with the coenzyme Q10 solution, the emulsions showed different degrees of heart, liver, spleen and brain targeting. The relative uptake rate of the 0.2% GM1-modified emulsion in the heart was 37.06, while that of the 1.0% GM1-modified emulsion in the brain was 17.43. These results strongly suggest that coenzyme Q10 emulsions coated with GM1 can tolerate freeze-thaw cycles and are excellent for treatment of cardiac and neurodegenerative diseases.

Abstract
Aim: A novel luteolin (LUT) loaded dual bionanocarrier ‘phytochylomicron’ was elaborated to allow LUT injectable delivery and liver cancer targeting. Methods: LUT–phospholipid complex was prepared and loaded into chylomicron nanocarrier. Then phytochylomicron underwent physicochemical characterization, cell culture and pharmacodynamics studies on a new liver-tumor model. Results: Phytochylomicron showed sustained release pattern with minimum drug leakage until reaching the liver. Cell culture studies showed high growth inhibition of Hep G2 cells with 2.6-fold enhancement in cellular uptake. Pharmacodynamics demonstrated enhanced tumor growth inhibition (sixfold) with a significant tumor size reduction. Finally, cell culture results demonstrated an excellent correlation with pharmacodynamics confirming the obtained findings. Conclusion: A novel phytochylomicron nanosystem was successfully elaborated with promising characteristics that promoted injectable LUT delivery and liver cancer targeting. [Formula: see text]

Abstract
Water-in-oil (w/o) simple emulsions are dispersed microconfined systems that find applications in many areas of advanced materials and biotechnology, such as the food industry, drug delivery, and cosmetics, to name but a few. In these systems, the structural and chemical properties of the boundary layer at the w/o interface are of paramount importance in determining functionality and stability. Recently, microfluidic methods have emerged as a valuable tool for fabricating monodisperse emulsion droplets. Because of the intrinsic flexibility of microfluidics, different interfaces can be obtained, and general principles governing their stability are needed to guide the experimental approach. Herein, we investigate the structural characteristics of the region encompassing the liquid/liquid (L/L) interface of w/o emulsions generated by a microfluidic device in the presence of phospholipid 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) and other intercalating amphiphiles (dopants) using microfocused small-angle X-rays scattering (μ-SAXS). We show that phospholipids provide a stable and versatile boundary film of ∼100 μm whose basic units are swollen and uncorrelated DMPC bilayers. The internal arrangement of this interfacial film can be tuned by adding molecules with a different packing parameter, such as cholesterol, which is able to increase the stiffness of the lipid membranes and trigger interbilayer correlation.

Abstract
Single-walled carbon nanotubes (SWCNTs) attract great interest in biomedical fields including application for drug delivery system. In this study, we developed a novel gene delivery system employing SWCNTs associated with polycationic and amphiphilic H-(-Lys-Trp-Lys-Gly-)7-OH [(KWKG)7] peptides having pegylation. SWCNTs wrapped with (KWKG)7 formed a complex with plasmid DNA (pDNA) in aqueous solution based on polyionic interaction but later underwent aggregation. On the other hand, a complex of pDNA and SWCNT-(KWKG)7 modified with polyethylene glycol (PEG) chains of 12 units [SWCNT-(KWKG)7-(PEG)12] afforded good dispersion stability for 24 h even in a cell culture medium. The in vitro cellular uptake of SWCNT-(KWKG)7-(PEG)12/pDNA complex prepared with fluorescence-labeled pDNA was evaluated with fluorescent microscopic observation and flow cytometry. The uptake by A549 human lung adenocarcinoma epithelial cells increased along with the extent of pegylation, suggesting the importance of dispersion stability in addition to the cationic charge which facilitates ionic cellular interaction. The expression of pDNA encoding the monomeric Kusabira-Orange 2 fluorescent protein in the form of the SWCNT-(KWKG)7-(PEG)12/pDNA complex demonstrated remarkable enhancement of transfection depending also on the extent of pegylation and the N/P ratio. The potential of the SWCNT composite wrapped with polycationic and amphiphilic (KWKG)7 with pegylation as a carrier for gene delivery was demonstrated.

Abstract
1. The aim of this study was to compare the pharmacokinetics (PKs) and tissue distribution of larotaxel (LTX) solution with a newly developed formulation called LTX-loaded folate-poly (PEG-cyanoacrylate-co-cholesteryl cyanoacrylate) (FA-PEG-PCHL)-modified liposomes in rats. 2. An ultra-performance liquid chromatography-tandem mass spectrometry method has been developed and validated for the determination of LTX in rat plasma and tissues to investigate the influence of FA-PEG-PCHL-modified lipid carrier on LTX PKs and tissue distribution. 3. The PK study result showed significantly higher area under the concentration-time curve (97.2%, **p < 0.01), slower clearance (49.2%, **p < 0.01) and lower volume of distribution (42.5%, **p < 0.01) in rats following intravenous administration of modified liposomes. The biodistribution results exhibited significantly lower uptake of LTX-loaded modified liposomes in heart (20.4%, **p < 0.01), lung (8.33%, **p < 0.01), muscle (13.4%, *p < 0.05) and spleen (15.0%, **p < 0.01) among all sampled tissues, indicating that the modified lipid carriers may avoid the trapping by the reticuloendothelial system and the modified liposomes may reduce toxicity in cardiovascular system compared to LTX solution. Moreover, markedly higher concentrations of LTX in the kidney (100%, **p < 0.01) were found in LTX-loaded modified liposome treated rats and could be explained by the high folate receptor level in kidney. 4. These results indicated that the FA-PEG-PCHL-modified liposome could be an effective parenteral carrier for the delivery of LTX in cancer treatment.

Abstract
The most widely used method for increasing uptake on macrophage is specific targeting for mannose receptor (MR) presented on macrophages. Efficiency of the uptake for MR is influenced by the space length and flexibility of mannose ligand in liposome (LP). We prepared mannosylated liposomes (M-EGn-LP-ICG) encapsulated indocyanine green (ICG) with mannose ligand of various ethylene glycol units (EG), LP-ICG, and mannosylated liposome (M-LP-ICG) incorporated with p-aminophenyl-α-d-mannopyranoside. We studied the effect of space length of the mannose ligand in vitro and in vivo with prepared liposomes. A space length of two ethylene glycol units at least was needed for uptake by macrophages and the uptake was increased as the space length increased up to EG4. We measured near-infrared (NIR) fluorescence intensity by ICG and the fluorescence value of cell-associated N-(4-nitrobenzo-2-oxa-1,3-diazole) (NBD) in liposome after cellular uptake. M-EG4-LP-ICG showed lower NIR fluorescence intensity but higher NBD fluorescence value than M-LP-ICG. The result of pre-treatment with d(+)-mannose as an inhibitor showed significant decreasing in uptake of mannosylated LP-ICG but no difference in LP-ICG. These were explained that mannosylated LP-ICG was taken up by macrophages through the MR and M-EG4-LP-ICG showed more specific uptake than M-LP-ICG. We obtained images as time passed in the NIR range after intravenous administration using a Balb/c mouse with inflammatory model. The results showed high uptake in liver at early time and rapid degradation of mannosylated LP-ICG. M-EG4-LP-ICG was more selectively taken up by macrophages than M-LP-ICG.

Nanoemulsion formulation of fisetin improves bioavailability and antitumour activity in mice. Int J Pharm 2012; 427:452-9.

Abstract
The natural flavonoid fisetin (3,3',4',7-tetrahydroxyflavone) has shown antitumour activity but its administration is complicated by its low water solubility. Our aim was to incorporate fisetin into a nanoemulsion to improve its pharmacokinetics and therapeutic efficacy. Solubility and emulsification tests allowed to develop an optimal nanoemulsion composed of Miglyol 812N/Labrasol/Tween 80/Lipoid E80/water (10%/10%/2.5%/1.2%/76.3%). The nanoemulsion had an oil droplet diameter of 153 ± 2 nm, a negative zeta potential (-28.4 ± 0.6 mV) and a polydispersity index of 0.129. The nanoemulsion was stable at 4 °C for 30 days, but phase separation occurred at 20 °C. Pharmacokinetic studies in mice revealed that the fisetin nanoemulsion injected intravenously (13 mg/kg) showed no significant difference in systemic exposure compared to free fisetin. However, when the fisetin nanoemulsion was administered intraperitoneally, a 24-fold increase in fisetin relative bioavailability was noted, compared to free fisetin. Additionally, the antitumour activity of the fisetin nanoemulsion in Lewis lung carcinoma bearing mice occurred at lower doses (36.6 mg/kg) compared to free fisetin (223 mg/kg). In conclusion, we have developed a stable nanoemulsion of fisetin and have shown that it could improve its relative bioavailability and antitumour activity.

Abstract
This review attempts to provide an updated compilation of studies reported in the literature pertaining to production of nanocarriers encasing peptides and/or proteins, in a way that helps the reader direct a bibliographic search and develop an integrated perspective of the subject. Highlights are given to bioactive proteins and peptides, with a special focus on those from dairy sources (including physicochemical characteristics and properties, and biopharmaceutical application possibilities of e.g. lactoferrin and glycomacropeptide), as well as to nanocarrier functional targeting. Features associated with micro- and (multiple) nanoemulsions, micellar systems, liposomes and solid lipid nanoparticles, together with biopharmaceutical considerations, are presented in the text in a systematic fashion.

Abstract
The aim of this study was to assess the potential of cinnarizine loaded in lipid emulsion to modify the pharmacokinetics, tissue distribution and safety of cinnarizine. The cinnarizine-loaded emulsion (CLE) which can remain stable over 18-month storage at 4+/-2 degrees C was prepared by high-pressure homogenization. Nicomp 380 particle sizing system and HPLC were used to evaluate CLE in vitro, while UPLC/MS/MS for pharmacokinetic and tissue distribution study. The pharmacokinetics and tissue distributions of CLE were assessed by comparing with the solution form after intravenous administration to rats at a dose of 2mg/kg. The CLE showed significant higher AUC and lower clearance and distribution volume than those of solution form. This helped cinnarizine to reach higher level in vessel, and circulate in the blood stream for a longer time resulting in better therapeutic effect. The tissue distribution exhibited significant lower uptake of CLE emulsion in lung and brain, indicating the advantage of CLE over the solution form in reducing drug precipitation in vivo and toxicity in CNS. Drug safety assessment studies including hemolysis test, intravenous stimulation and injection anaphylaxis revealed that the CLE was safe for intravenous injection.

Abstract
Lipid microspheres (LM) are excellent drug delivery or vaccines adjuvant systems and are relatively stable. The aim of this work is to develop and characterize a system that is able to encapsulate and present antigenic membrane proteins from Leishmania amazonensis. Membrane proteins are important for vaccine's formulation because these proteins come in contact with the host cell first, triggering the cell mediated immune response. This is a useful tool to avoid or inactivate the parasite invasion. The LM are constituted by soybean oil (SO), dipalmitoylphosphatidilcholine (DPPC), cholesterol and solubilized protein extract (SPE). The particles formed presented an average diameter of 200 nm, low polydispersion and good stability for a period of 30 days, according to dynamic light scattering assays. Isopycnic density gradient centrifugation of LM-protein showed that proteins and lipids floated in the sucrose gradient (5-50%w/v) suggesting that the LM-protein preparation was homogeneous and that the proteins are interacting with the system. The results show that 85% of SPE proteins were encapsulated in the LM. Studies of cellular viability of murine peritoneal macrophages show that our system does not present cytotoxic effect for the macrophages and still stimulates their NO production (which makes its application as a vaccine adjuvant possible). LM-protein loaded with antigenic membrane proteins from L. amazonensis seems to be a promising vaccine system for immunization against leishmaniasis.

Abstract
The entrapment efficiency (EE) and release in vitro are very important physicochemical characteristics of puerarin submicron emulsion (SME). In this paper, the performance of ultrafiltration (UF), ultracentrifugation (UC), and microdialysis (MD) for determining the EE of SME were evaluated, respectively. The release study in vitro of puerarin from SME was studied by using MD and pressure UF technology. The EE of SME was 86.5%, 72.8%, and 55.8% as determined by MD, UF, and UC, respectively. MD was not suitable for EE measurements of puerarin submicron oil droplet, which could only determine the total EE of submicron oil droplet and liposomes micelles, but it could be applied to determine the amount of free drug in SMEs. Although UC was the fastest and simplest to use, its results were the least reliable. UF was still the relatively accurate method for EE determination of puerarin SME. The release of puerarin SME could be evaluated by using MD and pressure UF, but MD seemed to be more suitable for the release study of puerarin emulsion. The drug release from puerarin SME at three drug concentrations was initially rapid, but reached a plateau value within 30 min. Drug release of puerarin from the SME occurred via burst release.

Abstract
Camptothecin is a topoisomerase I inhibitor that acts against a broad spectrum of cancers. However, its clinical application is limited by its insolubility, instability, and toxicity. The aim of the present study was to develop acoustically active nanoemulsions for camptothecin encapsulation to circumvent these delivery problems. The nanoemulsions were prepared using liquid perfluorocarbons and coconut oil as the cores of the inner phase. These nanoemulsions were stabilized by phospholipids and/or Pluronic F68 (PF68). The nanoemulsions were prepared at high drug loading of approximately 100% with a mean droplet diameter of 220-420 nm. Camptothecin in these systems showed retarded drug release. Camptothecin in nanoemulsions with a lower oil concentration exhibited cytotoxicity against melanomas and ovarian cancer cells. Confocal laser scanning microscopy confirmed nanoemulsion uptake into cells. Hemolysis caused by the interaction between erythrocytes and the nanoemulsions was investigated. Formulations with phosphatidylethanolamine as the emulsifier showed less hemolysis than those with phosphatidylcholine. Using a 1 MHz ultrasound, an increased release of camptothecin from the system with lower oil concentration could be established, illustrating a drug-targeting effect.

Abstract
In this study, an injectable microemulsion of arsenic trioxide (As2O3-M) was prepared for intratumoral injection and the suppressive effect of As2O3-loaded microemulsion on human breast cancer cells MCF-7 was compared with those of a solution of the drug. Microemulsion was made up of soybean oil as oil phase, a mixture of Brij 58 and Span 80 as surfactants, absolute ethanol as cosurfactant, and bidistilled water containing As2O3 solution as the aqueous phase. Microemulsion formulation contains 5 x 10(-6) M As2O3. The pH of As2O3-M was adjusted to 7.35 +/- 0.1 and the physicochemical stability of the formulation was observed. The particle size distribution and zeta potential of As2O3-M were measured by Zetasizer 3000 HSA. The mean droplet diameters of As2O3-M were determined as 8.6 +/- 0.4 nm. As2O3-M exhibited 13.1 +/- 0.9 mV zeta potential. The formulation was physically stable for 12 months at room temperature when kept in ampule forms, as well as after autoclaving at 110 degrees C for 30 min. The antitumor effects of As2O3-M were examined on human breast cancer cells MCF-7. It was clearly demonstrated that As2O3-M had a significant cytotoxic effect on breast cancer cell lines, and the cytotoxic effect of As2O3-M was significantly more than that of regular As2O3 solutions. Even approximately 3000 times diluted microemulsion formulation loaded with 5 x 10(-6) M As2O3 showed a cytotoxic effect. As a result, this diluted concentration (approximately 1.6 x 10(-9) M) was found 1000 times more effective than regular As2O3 solutions (5 x 10(-6) M). According to the in vitro cytotoxicity studies, we concluded that when As2O3 was incorporated into the microemulsion (As2O3-M), which is a new drug carrier system, it suppresses tumor cell growth on multiple tumor lines. These results indicate that As2O3-M may exert a low cytotoxic effect on normal cells and may be effective as an antitumor agent that induces apoptosis.

Abstract
Cell-specific drug delivery is one of the most promising strategies for improving therapeutic efficiency and minimizing systemic toxicity. Carrier systems devoted to receptor-mediated targeting need to be developed. In the case of liver-non-parenchymal cell-specific targeting systems, glycosylated emulsions have been developed as carriers for lipophilic drugs and/or peptides. This present study demonstrates the in vivo disposition behaviour and pharmacokinetic characteristics of mannosylated (Man-) and fucosylated (Fuc-) emulsions incorporated with cholesten-5-yloxy-N-(4-((1-imino-2-D-thiomannosylethyl)amino)alkyl)formamide (Man-C4-Chol) and its fucosylated derivatives (Fuc-C4-Chol), respectively. Man- (or Fuc-) emulsions are composed of soybean oil, EggPC and Man-C4-Chol (or Fuc-C4-Chol) in a weight ratio of 70:25:5. After intravenous administration to mice, these two types of [(3)H]cholesteryl hexadecyl ether (CHE)-labelled glycosylated emulsions were rapidly eliminated from the blood circulation and preferentially recovered in the liver. In contrast, bare (Bare-) emulsions composed of soybean oil:EggPC:cholesterol (Chol) in a weight ratio of 70:25:5 were more retained in the blood circulation. The hepatic uptake clearances of Man- and Fuc-emulsions were 3.3- and 4.0-times greater than that of Bare-emulsions. Interestingly, the hepatic uptake clearance of Fuc-emulsions was significantly higher that that of Man-emulsions. The uptake ratios by non-parenchymal cells (NPC) and parenchymal cells (PC) (NPC/PC ratio) for Bare-, Man- and Fuc-emulsions were found to be 0.4, 2.0 and 2.9, respectively. The hepatic uptakes of [(3)H]CHE-labelled Man- and Fuc-emulsions were reduced by pre-dosing with glycosylated proteins and liposomes. These results clearly support the conclusion that Man- and Fuc-emulsions are promising carrier systems for liver NPC-specific targeting via receptor-mediated mechanism.

Abstract
Continuous monitoring of hematocrit with a CRIT-LINE monitor (CLM) is used to prevent excess ultrafiltration during hemodialysis and continuous renal replacement therapy. The presence of substances affecting the scattering and absorption rates of multiple wavelengths of near infrared rays of CLM in the blood may affect the measured values with CLM. We examined the influences of lipid emulsion (LE) on hematocrit and relative blood volume (RBV) which were measured with CLM using an in vitro experimental model with human blood. Additions of 10% or 20% of LE increased the hematocrit measured by LCM and decreased the percent change of RBV in proportion to the dose. One percentage of 20% LE in the plasma increased the expected hematocrit measured with CLM by 2.9%. The decrease of initial hematocrit from 48.1% to 43.4% decreased the expected percent change of RBV from -3.4% to -3.7% with the addition of 1 ml of 20% LE to 100 ml blood. These findings indicate that additions of LE increase hematocrit that is measured with CLM in proportion to the dose of LE. Low levels of initial hematocrit will increase the degree of expected percent change of RBV. Attention should be paid to the influence of LE during monitoring with CLM.

Abstract
An emulsion system composed of vitamin E, coconut oil, soybean phosphatidylcholine, non-ionic surfactants, and polyethylene glycol (PEG) derivatives (referred to as the tocol emulsion) was characterized in terms of its physicochemical properties, drug release, in vivo efficacy, toxicity, and stability. Systems without vitamin E (referred to as the lipid emulsion) and without any oils (referred to as the aqueous micelle system) were prepared for comparison. A lipophilic antioxidant, resveratrol, was used as the model drug for emulsion loading. The incorporation of Brij 35 and PEG derivatives reduced the vesicle diameter to <100nm. The inclusion of resveratrol into the emulsions and aqueous micelles retarded the drug release. The in vitro release rate showed a decrease in the order of aqueous micelle system>tocol emulsion>lipid emulsion. Treatment of resveratrol dramatically reduced the intimal hyperplasia of the injured vascular wall in rats. There was no significant difference in this reduction when resveratrol was delivered by either emulsion or the aqueous micelle system. The percentages of erythrocyte hemolysis by the emulsions and aqueous micelle system were approximately 0 and approximately 10%, respectively. Vitamin E prevented the aggregation of emulsion vesicles. The mean vesicle size of the tocol emulsion remained unchanged during 30 days at 37 degrees C. The lipid emulsion and aqueous micelle system, respectively, showed 11- and 16-fold increases in vesicle size after 30 days of storage.

This study investigates the submicron lipid emulsion as a potential parenteral drug delivery system for nalbuphine and its ester prodrugs. Submicron emulsions were prepared using egg phospholipid as the main emulsifier, various co-emulsifiers were also incorporated, including Brij 30, Brij 98, and stearylamine. Squalene as the oil phase formed stable emulsions with small particles. Drug release was affected by incorporating various co-emulsifiers and drugs with various lipophilicity. The loading of nalbuphine into lipid emulsions resulted in the slower and sustained release of nalbuphine. Lipid emulsions containing Brij 98 could further enhance the release of prodrugs as compared to the aqueous solution (control) especially for nalbuphine enanthate (NAE). Hemolysis caused by the interaction between erythrocytes and lipid emulsions was investigated. Brij 30 and Brij 98 could shield the hemolytic activity of phospholipids in the oil/water interface, decreasing the acute toxicological potential of the emulsions. The in vivo analgesic activity of various emulsions was examined by a cold ethanol tail-flick test. The analgesic duration and potency were significantly increased by incorporating nalbuphine and NAE into Brij 98-containing emulsions. There was no need for nalbuphine benzoate (NAB) to show a controlled delivery manner by encapsulating into emulsions, since NAB itself could prolong the analgesic duration of nalbuphine due to the slow enzyme degradation. The in vivo analgesic activity correlated well to the profiles of in vivo pharmacokinetic profiles. The study demonstrates the feasibility of using submicron lipid emulsion as the parenteral drug delivery system for nalbuphine and its prodrugs.

Abstract
All-trans retinoic acid (ATRA) was incorporated into lipid emulsions in an attempt to alter its distribution characteristics and improve its inhibition of liver cancer metastasis. Lipid emulsions composed of egg phosphatidylcholine, cholesterol, and soybean oil were the optimized carriers for ATRA delivery, as shown by the submicron particle size and high incorporation efficiency. The particle size and zeta potential of ATRA incorporated into emulsions were about 133 nm and -11 mV, respectively. In vitro drug release study demonstrated that the release of ATRA from emulsions was sustained in the absence and present of bovine serum albumin, suggesting that ATRA was stable when incorporated in emulsions. After intravenous administration in mice, [3H]cholesteryl hexadecyl ether incorporated into emulsion, which is the inherent distribution of emulsions, accumulated gradually mainly in the liver. The blood concentration and hepatic accumulation of [3H]ATRA incorporated into emulsion was significantly higher than that of serum dissolving [3H]ATRA, which represent the original distribution characteristic of free ATRA. In a murine liver metastasis model by colon adenocarcinoma, the liver metastasis number and liver weight were significantly reduced and the survival time of mice was prolonged following intravenous injection of ATRA incorporated into emulsions.

Abstract
Carbohydrate grafted emulsions are one of the most promising cell-specific targeting systems for lipophilic drugs. We have previously reported that mannosylated (Man-) emulsions composed of soybean oil, EggPC and cholesten-5-yloxy-N-(4-((1-imino-2-d-thiomannosylethyl)amino)alkyl)formamide (Man-C4-Chol) with a ratio of 70:25:5 were significantly delivered to liver non-parenchymal cells (NPC) via mannose receptor-mediated mechanism after intravenous administration in mice. Since the efficient targeting through a receptor-mediated mechanism is largely controlled by ligand-receptor interaction, the effect of mannose density on Man-emulsions was studied with regard to both the disposition in vivo in mice and the uptake in vitro, using elicited macrophages which express a number of mannose receptors. After intravenous injection, Man-emulsions with 5.0% (Man-5.0-emulsions) and 7.5% (Man-7.5-emulsions) of Man-C4-Chol were rapidly eliminated from the blood circulation and preferentially accumulated in the liver-NPC compared with Man-emulsions with 2.5% of Man-C4-Chol (Man-2.5-emulsions) and bare emulsions (Bare-emulsions). The in vitro study showed increased internalization of Man-5.0- and Man-7.5-emulsions and significant inhibition of uptake in the presence of mannan. The enhanced uptake of Man-emulsions was related to the increasing of Man-C4-Chol content that corresponded to confocal microscopy study. These results suggest that the mannose density of Man-emulsions plays an important role in both cellular recognition and internalization via a mannose receptor-mediated mechanism.

Abstract
BACKGROUND (-)-Epigallocatechin gallate (EGCG), the main active polyphenol in green tea, is associated with antioxidant and anticancer activities. OBJECTIVE The aim of this study was to evaluate the feasibility of using liposomes for intratumor distribution of EGCG and its derivative, (+)-catechin. METHOD Liposomes containing egg phosphatidylcholine, cholesterol, or anionic surfactant in the presence of 15% ethanol were prepared. The physicochemical characteristics including vesicle size, zeta potential, drug entrapment, and drug release of liposomal formulations were determined. The liposomes containing EGCG were injected into basal cell carcinomas (BCCs), melanomas, and colon tumors to examine the tumor uptake of the drug. Liposomes were also incubated with a given number of BCC cells, and the cell viability was estimated. RESULT Almost no drug molecules were observed when free EGCG was administered to BCCs. EGCG encapsulated in liposomes with deoxycholic acid (DA) and ethanol increased drug deposition by 20-fold as compared to the free form. The larger vesicle size of this formulation was suggested to be the predominant factor governing this enhancement. The liposomes without ethanol showed low or negligible enhancement on EGCG uptake in BCCs. Liposomes protected EGCG from degradation, resulting in the induction of greater BCC death compared to that by free EGCG at lower concentrations. CONCLUSION These results suggest that the intratumor injection of liposomes containing EGCG with moderate modification is an effective approach for increasing EGCG deposition in BCCs.

Abstract
Galactosylated (Gal) emulsions containing various molar ratios of cholesten-5-yloxy-N-(4-((1-imino-2-D-thiogalactosylethyl)amino)butyl)formamide (Gal-C4-Chol) as a ligand for asialoglycoprotein receptors were prepared to study the effect of the galactose content of Gal-emulsions labeled with [3H]cholesteryl hexadecyl ether on their targeted delivery to hepatocytes. The uptake characteristics of Gal-emulsions having Gal-C4-Chol of 1, 3, 4, 6, and 9 mol% were evaluated in HepG2 cells which possess asialoglycoprotein receptors and NIH3T3 cells which are lack of asialoglycoprotein receptors. The uptake and internalization by HepG2 cells was enhanced by the addition of Gal-C4-Chol to the Gal-emulsions whereas the uptake of Gal-emulsions by NIH3T3 cells was not much and was comparable with that of bare-emulsions. In the presence of excess Gal-BSA, the uptake of Gal-emulsions having Gal-C4-Chol of 4, 6, and 9% was inhibited suggesting asialoglycoprotein receptor mediated uptake. Moreover, Gal-emulsions having Gal-C4-Chol of 4, 6, and 9% showed a slight increase in surface binding and exhibited extensive uptake and internalization into HepG2 cells. The present study strongly suggested that the Gal-emulsions are taken up by the asialoglycoprotein receptor-mediated endocytosis and galactose density of Gal-emulsions is important for effective recognition and cell internalization.

Abstract
For effective chemotherapy, it is necessary to deliver therapeutic agents selectively to their target sites, since most drugs are associated with both beneficial effects and side effects. The use of lipid dispersion carrier systems, such as lipid emulsions and liposomes, as carriers of lipophilic drugs has attracted particular interest. A drug delivery system can be defined as a methodology for manipulating drug distribution in the body. Since drug distribution depends on the carrier, administration route, particle size of the carrier, lipid composition of the carrier, electric charge of the carrier and ligand density of the targeting carrier, these factors must be optimized. Recently, the lipid carrier system has also been applied to gene delivery systems for gene therapy. However, in both drug and gene medicine cases, a lack of cell-selectivity limits the wide application of this kind of drug and/or gene therapy. Therefore, lipid carrier systems for targeted drug and gene delivery must be developed for the rational therapy. In this review, we shall focus on the progress of research into lipid carrier systems for drug and gene delivery following systemic or local injection.
