Abstract
Tacrolimus is one of the most commonly used immunosuppressive agents in animal models of transplantation. However, in these models, oral administration is often problematic due to the lowered compliance associated with highly invasive surgery and due to malabsorption in the intestinal tract. Therefore, we carried out a study to determine the pharmacokinetics of tacrolimus after intramuscular (IM) injection and to determine the optimal IM dosing regimens in primate models. Six male cynomolgus monkeys (Macaca fascicularis) were used in the study. Doses of 0.1 mg/kg and 5 mg were administered via IM injection and oral administration, respectively, once to determine single-dose pharmacokinetics and once daily for 5 days to determine multiple-dose pharmacokinetics. According to pharmacokinetic model estimates, the inter- and intra-individual variabilities in bioavailability following IM injection were remarkably reduced compared with those following oral administration. Monte Carlo simulations revealed that Cpeak, Ctrough and AUC would also have less variability following IM injection compared with oral administration. In this study, we found that the pharmacokinetic characteristics of tacrolimus were more constant following IM injection compared with oral administration. These results suggest that IM injection can be an alternative route of administration fin non-human primate model studies.

Abstract
For performance assessment of the lipid-based drug delivery systems (LBDDSs), in vitro lipolysis is commonly applied because traditional dissolution tests do not reflect the complicated in vivo micellar formation and solubilization processes. Much of previous research on in vitro lipolysis has mostly focused on rank-ordering formulations for their predicted performances. In this study, we have incorporated in vitro lipolysis with microsomal stability to quantitatively predict the oral bioavailability of a lipophilic antineoplastic drug bexarotene (BEX) administered in LBDDS. Two types of LBDDS were applied: lipid solution and lipid suspension. The predicted oral bioavailability values of BEX from linking in vitro lipolysis with microsomal stability for lipid solution and lipid suspension were 34.2 ± 1.6% and 36.2 ± 2.6%, respectively, whereas the in vivo oral bioavailability of BEX was tested as 31.5 ± 13.4% and 31.4 ± 5.2%, respectively. The predicted oral bioavailability corresponded well with the oral bioavailability for both formulations, demonstrating that the combination of in vitro lipolysis and microsomal stability can quantitatively predict oral bioavailability of BEX. In vivo intestinal lymphatic uptake was also assessed for the formulations and resulted in <1% of the dose, which confirmed that liver microsomal stability was necessary for correct prediction of the bioavailability.

Abstract
The intestinal lymphatic system plays an important role in the pathophysiology of multiple diseases including lymphomas, cancer metastasis, autoimmune diseases, and human immunodeficiency virus (HIV) infection. It is thus an important compartment for delivery of drugs in order to treat diseases associated with the lymphatic system. Lipophilic prodrug approaches have been used in the past to take advantage of the intestinal lymphatic transport processes to deliver drugs to the intestinal lymphatics. Most of the approaches previously adopted were based on very bulky prodrug moieties such as those mimicking triglycerides (TG). We now report a study in which a lipophilic prodrug approach was used to efficiently deliver bexarotene (BEX) and retinoic acid (RA) to the intestinal lymphatic system using activated ester prodrugs. A range of carboxylic ester prodrugs of BEX were designed and synthesised and all of the esters showed improved association with chylomicrons, which indicated an improved potential for delivery to the intestinal lymphatic system. The conversion rate of the prodrugs to BEX was the main determinant in delivery of BEX to the intestinal lymphatics, and activated ester prodrugs were prepared to enhance the conversion rate. As a result, an 4-(hydroxymethyl)-1,3-dioxol-2-one ester prodrug of BEX was able to increase the exposure of the mesenteric lymph nodes (MLNs) to BEX 17-fold compared to when BEX itself was administered. The activated ester prodrug approach was also applied to another drug, RA, where the exposure of the MLNs was increased 2.4-fold through the application of a similar cyclic activated prodrug. Synergism between BEX and RA was also demonstrated in vitro by cell growth inhibition assays using lymphoma cell lines. In conclusion, the activated ester prodrug approach results in efficient delivery of drugs to the intestinal lymphatic system, which could benefit patients affected by a large number of pathological conditions.

Abstract
OBJECTIVE To evaluate the potential pharmacokinetic interactions of the anticancer agent gefitinib (Iressa®) and the oriental medications Guipi Decoction (, GPD, Guibi-tang in Korean) and Bawu Decoction (, BWD, Palmul-tang in Korean). METHODS Methylcellulose (MC, control), GPD (1,200 mg/kg), or BWD (6,000 mg/kg) was orally administered to rats either as a single dose or multiple doses prior to gefitinib administration. To examine the effects of a single dose of the herbal medicines, gefitinib (10 mg/kg) was orally administered after 5 min or 1 h of MC or the herbal medicine pretreatments. To examine the effects of the multiple doses of the herbal medicines, gefitinib (10 mg/kg) was orally administered following 7 consecutive days of the administration of MC or each herbal medicine. The plasma concentrations of gefitinib were determined with liquid chromatography-tandem mass spectrometry assay. The plasma concentration-time profiles of gefitinib were analyzed with a noncompartmental analysis. RESULTS Gefitinib was rapidly absorbed and showed a monoexponential decline with an elimination half-life of 3.7-4.1 h. The pharmacokinetics of gefitinib was not affected by GPD pretreatment. However, a significantly lower maximum plasma concentration (Cmax, P<0.05) and area under the curve (P<0.05), and a delayed time to reach Cmax (Tmax, P<0.01) were observed in both single- and multipledose BWD-pretreated rats compared with the control rats. CONCLUSIONS BWD and not GPD might delay and interfere with gefitinib absorption. Further evaluations of the clinical significance of these findings are needed.

Abstract
S-1 (TS-1®) is an oral fluoropyrimidine anticancer agent containing tegafur, oteracil, and gimeracil. Sipjeondaebo-tang (SDT) is a traditional oriental herbal medicine that has potential to alleviate chemotherapy-related adverse effects. The aim of the present study was to evaluate the effect of SDT on the pharmacokinetics of S-1. Sprague-Dawley rats were pretreated with a single dose or repeated doses of SDT for seven consecutive days (1200 mg/kg/day). After the completion of pretreatment with SDT, S-1 was orally administered and plasma concentrations of tegafur, its active metabolite 5-FU, and gimeracil were determined by liquid chromatography-tandem mass spectrometry (LC/MS/MS). A population pharmacokinetic model was developed to evaluate the effect of SDT on pharmacokinetics of tegafur and 5-FU. Although a single dose of SDT did not have any significant effect, the absorption rate of tegafur decreased, and the plasma levels of 5-FU reduced significantly in rats pretreated with SDT for seven days in parallel to the decreased gimeracil concentrations. Population pharmacokinetic modeling also showed the enhanced elimination of 5-FU in the SDT-pretreated group. Repeated doses of SDT may inhibit the absorption of gimeracil, an inhibitor of 5-FU metabolism, resulting in enhanced elimination of 5-FU and decrease its plasma level.

Abstract
Background Fimasartan (FMS) is a potent angiotensin receptor blocker for the treatment of mild to moderate hypertension. This study aimed to evaluate the transfer of FMS to fetus and breast milk in rats. Methods In order to study the transfer to the fetus and nursing pup, pregnant and nursing maternal rats were administered with FMS by a constant intravenous infusion to reach target plasma concentrations of 200 ng/mL and 100 ng/mL. The concentrations of FMS in plasma, placenta, amniotic fluid, fetus, and milk were determined by a validated LC-MS/MS assay. Results Upon constant intravenous infusion, the plasma FMS concentration reached the target steady state concentrations (Css = 200 ng/mL and 100 ng/mL) in 24 h. The tissue-to-plasma partition coefficients (Kp) for placenta, amniotic fluid, and milk were obtained based on the observed FMS concentrations in the tissues and Css. The Kp values for all tissues were not different between high (Css = 200 ng/mL) and low (Css = 100 ng/mL) dose groups. While the mean Kp of the placenta was 44.6–59.0 %, the mean Kp was 1.3–1.7 % for the amniotic fluid and 14.9–17.0 % for fetus. The mean Kp of milk was 10.4–15.2 %. Conclusions Placental transfer and milk excretion of FMS was relatively lower compared to other angiotensin receptor blockers.

Abstract
OBJECTIVES This study was conducted to examine the tissue distribution of human recombinant epidermal growth factor (EGF) after multiple intravenous and subcutaneous injections in mice. METHODS Male BALB/c mice were divided into (1) EGF 1 mg/kg intravenous dose, (2) EGF 5 mg/kg intravenous dose, (3) drug-free intravenous control, (4) EGF 1 mg/kg subcutaneous dose, (5) EGF 5 mg/kg subcutaneous dose and (6) drug-free subcutaneous control groups. EGF and drug-free dosing solutions were injected by intravenous and subcutaneous injections once a day for 3 days. EGF concentrations in serum and tissues of kidney, liver, lung, small intestine and tongue were determined by ELISA. KEY FINDINGS As the intravenous and subcutaneous doses were increased from 1 to 5 mg/kg, serum Cmax and area under the concentration-time curve (AUC) values were increased dose-proportionally. In lung, tongue and small intestine, increases in AUC were dose-proportional after intravenous injections, but greater than dose-proportional after subcutaneous injections. The fold-increases in Cmax and AUC values were lowest in liver and highest in kidney. CONCLUSION Based on Cmax and AUC data, the systemic exposure achieved by subcutaneous injections was comparable with that achieved by intravenous injections.

Abstract
This study describes the development of a sensitive liquid chromatography-electrospray-tandem mass spectrometry method for the simultaneous determination of benzyl butyl phthalate (BBP) and its major metabolites, monobenzyl phthalate (MBzP) and monobutyl phthalate (MBuP), in rat plasma, urine, and 10 different tissues. The method was validated with regard to the specificity, linearity, precision, accuracy, lower limit of quantification (LLOQ), recovery, and stability by using the matrix-matched quality control samples. The assay achieved LLOQ of 1 ng/ml of BBP for plasma and urine, 4 ng/g for kidney and liver, 10 ng/g for fat, and 20 ng/g for all other tissues. For MBzP and MBuP, the assay achieved LLOQ of 5 ng/ml for plasma and urine, 10 ng/g for fat, and 20 ng/g for all other tissues. The disposition of BBP was characterized by a large volume of distribution (71.1-82.9 l/kg) and a high clearance (838.7-871.0 ml/min/kg). It was extensively metabolized to MBzP and MBuP, with their levels consistently exceeding the BBP levels. The distribution of BBP, MBzP, and MBuP to tissues of kidney, liver, stomach, small intestine, large intestine, spleen, brain, testis, thyroid, and fat was determined under steady-state conditions. For BBP, the steady-state tissue-to-plasma partition coefficient (K p) was the highest for fat (25.0) followed by small intestine (2.6), thyroid (2.0), and stomach (1.1). In contrast, for MBzP and MBuP, it was the highest for kidney (2.0 and 4.3, respectively) and liver (4.3 and 2.1, respectively) but was less than unity for all other tissues. The developed assay method and findings of this study may be useful to evaluate the exposure and toxic potential of BBP and its metabolites in risk assessment.

Abstract
Chloroacetamide (CAA) is a preservative used in various cosmetic, personal care and household products. Due to the hazard potential for allergic reaction and reproductive toxicity, CAA is being considered a high priority for screening assessment and toxicological re-evaluation. This study describes the development of a highly specific and sensitive atmospheric pressure chemical ionization tandem mass spectrometry method for the determination of CAA in rat plasma and its application to a topical bioavailability study. Chromatographic separations were achieved on a C8 column using a highly aqueous mobile phase with a binary gradient elution. The assay was linear in the concentration range of 5-2,500 ng/mL (r ≥ 0.995) using a small sample volume (100 µL). Applicability of the assay was demonstrated in a bioavailability study in rats after i.v. injection (0.5 or 2 mg/kg) and topical application (7.02 mg/kg). Average elimination half-life and clearance ranged from 26.6 to 30.5 min and 53.9 to 57.3 mL/min/kg, respectively. Upon topical application, CAA was slowly but steadily absorbed for a prolonged time period (12 h). The topical bioavailability was 53.5 and 48.3% for emulsion and lotion, respectively. The developed assay may be useful to examine the relationship between exposure and toxic potential of CAA in risk assessment.

Abstract
PURPOSE To compare the cerebral uptake and binding potential of [18 F]FCWAY and [18 F]Mefway in the rodent to assess their potential for imaging serotonin 1A (5-HT1A ) receptors. MATERIALS AND METHODS In vitro liver microsomal studies were performed to evaluate the degree of defluorination. Dynamic positron emission tomography (PET) studies were then conducted for 2 h with or without an anti-defluorination agent. The regions of interest were the hippocampus and frontal cortex (5-HT1A target regions) and the cerebellum (5-HT1A nontarget region). The in vivo kinetics of the radioligands were compared based on the brain uptake values and target-to-nontarget ratio. We also performed a comparison of binding potential (BPND ) as a steady-state binding parameter. Finally, binding affinities to 5-HT1A receptors were assessed in Chinese hamster ovary cells (CHO-K1) cells expressing human recombinant 5-HT1A receptors. RESULTS The radiochemical yield of [18 F]Mefway was slightly higher than that of [18 F]FCWAY (19 vs. 15%). With regard to metabolic stability against defluorination, both compounds exhibited similar stability in rat liver microsomes, but [18 F]Mefway displayed higher stability in the human microsome (defluorination ratio at 30 min: 32 vs. 29 in rat liver microsomes, 31 vs. 64 in human liver microsomes for [18 F]Mefway and [18 F]FCWAY, respectively). There were no significant differences in brain uptake, the target-to-nontarget ratios, and the BPND (at hippocampus, peak brain uptakes: 6.9 vs. 8.5, target-to-nontarget ratios: 6.9 vs. 8.5, BPND : 5.2 vs. 6.2 for [18 F]Mefway and [18 F]FCWAY). The binding affinity of [18 F]Mefway was considerably higher than that of [18 F]FCWAY (IC50 : 1.5 nM vs. 2.2 nM). CONCLUSION [18 F]Mefway exhibits favorable characteristics compared to [18 F]FCWAY in rodents, and may be a promising radioligand for use in human subjects.

Abstract
Homosalate (HMS) is an ultraviolet (UV) filtering agent used in sunscreens and other cosmetics for skin protection purposes. Despite the widespread use of these products, absorption, disposition, and in vivo endocrine disrupting potential of HMS have not been characterized. Thus, the aim of this study was to examine the percutaneous absorption, disposition, and exposure assessment of HMS in rats. Initially, sunscreen preparations of petrolatum jelly, oily solution, lotion, and gel were prepared and evaluated for in vitro permeation of HMS across excised rat skin. Dermal permeability was greatest for gel, and this preparation was used in subsequent in vivo topical application investigations. After iv injection (0.5, 2, or 5 mg/kg), the pharmacokinetics of HMS was linear and was characterized by a large Vd(ss) (13.2-17 L/kg), high Cl(s) (4.5-6.1 L/h/kg), and long t½ (6.1-8.4 h). After topical application of gel, the bioavailability of HMS was 5.4 ± 1.1 and 4.2 ± 0.6% for high and low doses (10 and 20 mg), respectively. Consistent with the prolonged absorption (Tmax 11.2 ± 1.8 and 12 ± 0 h for low and high doses, respectively), the terminal t½ was longer after topical application (23.6-26.1 h) compared to iv injection. A population pharmacokinetic model was further developed to simultaneously fit the time courses of plasma concentrations and dermal content data after iv injection and topical application. Findings of this study may be useful to further examine the relationship between exposure and endocrine disrupting potential of HMS in risk assessment.

Abstract
Purpose. This study describes the development of a rapid and sensitive LC-ESI-MS assay for simultaneous enantioselective determination of levocetirizine and pseudoephedrine in dog plasma in the presence of dextrocetirizine. Methods. Separations were achieved on an Ultron ES-OVM chiral column using the mobile phase consisting of 10 mM aqueous NH4OAc (pH 6.6) and acetonitrile (9:1 v/v). Results. The retention times of pseudoephedrine, dextrocetirizine, levocetirizine and diazepam (internal standard) were 5.2, 8.3, 9.6 and 11.6 min, respectively, and the total run time was less than 15 min. The assay was validated to demonstrate the linearity, accuracy and precision, recovery and stability. The calibration curves were linear over the concentration range from 1 – 200 ng/mL for levocetirizine and from 5 – 1000 ng/mL for pseudoephedrine. Conclusions. The developed assay was successfully applied to a pharmacokinetic study after oral administration of the racemic cetirizine (0.5 mg/kg, or 0.25 mg/kg as levocetirizine) and pseudoephedrine (12 mg/kg) in the dog.

Abstract
Fimasartan, 2-butyl-5-dimethylaminothiocarbonylmethyl-6-methyl-3-[[2'-(1H tetrazol -5-yl)biphenyl-4-yl]methyl]pyrimidin-4(3H)-one (BR-A-657), is a novel angiotensin II receptor blocker exhibiting potent and selective AT1 receptor blocking activity. This study reports the liquid chromatography-tandem mass spectrometry assay for the simultaneous determination of fimasartan and its active metabolite, BR-A-557, in rat plasma. The assay was validated to demonstrate the specificity, linearity, recovery, lower limit of quantification, accuracy, precision and stability. The multiple reaction monitoring was based on the transition of m/z 502.1 → 207.1 for fimasartan, 486.2 → 207.1 for BR-A-557 and 526.1 → 207.1 for BR-A-563 (internal standard). The assay utilized a simple precipitation procedure with acetonitrile and isocratic elution. The LLOQ was 0.2 ng/mL for fimasartan and BR-A-557 using 50 μL plasma samples. The assay was linear over a concentration range from 0.2 to 500 ng/mL for fimasartan and BR-A-557, with correlation coefficients >0.9995. The intra- and inter-day assay accuracies were 93.6-108.0 and 90.8-101.4% for fimasartan and 102.2-107.1 and 99.6-103.3% for BR-A-557, respectively. The intra- and inter-day precision were 2.4-4.4 and 3.0-13.4% for fimasartan and 3.1-5.2 and 2.8-9.8% for BR-A-557, respectively. The developed assay may be used to study the metabolism and mechanistic pharmacokinetics of fimasartan in future studies.

Abstract
PURPOSE The objectives of this study were to develop physiologically based models for the pharmacokinetics (PK) and organ distribution of apicidin in rats and mice and to predict human PK in blood and organs. METHODS The PK of apicidin was characterized in rats and mice after i.v. bolus injection, and distribution to various tissues was determined in rats following i.v. infusions at steady state. The developed models were prospectively validated within rat and within mouse and by scaling from rat to mouse using data after multiple i.v. injections. Human PK was predicted by the physiologically based modeling using intrinsic clearance data for humans from in vitro experiments. RESULTS The Cl(s) predicted for human (9.8 ml/min/kg) was lower than those found in mice (116.9 ml/min/kg) and rats (61.6 ml/min/kg), and the V(ss) predicted for human (1.9 l/kg) was less than in mice (2.0 l/kg) and rats (2.5 l/kg). Consequently, the predicted t (1/2) was longer in human (2.3 h) than in mice and rats (0.4 and 0.9 h, respectively). The highest concentrations of apicidin were predicted in liver followed by adipose tissue, kidney, lung, spleen, heart, arterial blood, venous blood, small intestine, stomach, muscle, testis, and brain. CONCLUSIONS The developed models adequately described the PK of apicidin in rats and mice and were applied to predict human PK. These models may be useful in predicting human blood and tissue concentrations of apicidin under different exposure conditions.

Abstract
The objective of this study was to predict the exposure to bisphenol A (BPA) after oral intake in human blood and tissues using physiologically based pharmacokinetic (PBPK) modeling. A refined PBPK model was developed taking into account of glucuronidation, biliary excretion, and slow absorption of BPA in order to describe the second peak of BPA observed following oral intake. This developed model adequately described the second peak and BPA concentrations in blood and various tissues in rats after oral administration. A prospective validation study in rats additionally supported the proposed model. For extrapolation to humans, a daily oral BPA dose of 0.237 mg/70 kg/d or 0.0034 mg/kg/d was predicted to achieve an average steady-state blood concentration of 0.0055 ng/ml (median blood BPA concentration in Korean pregnant women). This dose was lower than the reference dose (RfD, 0.016 mg/kg/d) and the tolerable daily intake established by the European Commission (10 μg/kg/d). Data indicate that enterohepatic recirculation may be toxicologically important as this pathway may increase exposure and terminal half-life of BPA in humans.

Abstract
Zearalenone, a mycotoxin biosynthesized by various Fusarium fungi, is widely found as a contaminant in grains and animal feeds. This study describes a rapid and sensitive LC/MS/MS assay method for the quantification of zearalenone in rat serum. The assay was validated to demonstrate the specificity, linearity, recovery, lower limit of quantification (LLOQ), accuracy and precision. The multiple reaction monitoring was based on the transition of m/z 317.0 --> 130.9 for zearalenone and 319.0 --> 204.8 for zearalanone (internal standard). The assay utilized a single liquid-liquid extraction with t-butyl methyl ether and isocratic elution, and the LLOQ was 0.5 ng/mL using 0.1 mL rat serum. The assay was linear over a concentration range from 0.5 to 200 ng/mL, with correlation coefficients >0.9996. The mean intra- and inter-day assay accuracy was 101.2-112.9 and 96.3-108.0%, respectively. The mean intra- and inter-day precision was between 1.3-7.6 and 3.6-10.6%, respectively. The developed assay was applied to a pharmacokinetic study after a bolus intravenous injection of zearalenone in rats.

Abstract
This study was conducted to predict the pharmacokinetics of oleanolic acid in humans based on animal data by allometry and several species-invariant time methods. Oleanolic acid was injected intravenously to mice, rats, rabbit and dogs (dose 1 mg/kg). The serum concentration-time profiles of oleanolic acid were best described by bi-exponential equation in all animal species. The average Cl, V ( ss ) and t ( 1/2 ) were 0.065 L/h, 0.019 L and 28.7 min in mice, 0.47 +/- 0.06 L/h, 0.117 +/- 0.029 L and 29.7 +/- 12.2 min in rats, 2.77 +/- 0.88 L/h, 1.83 +/- 0.60 L and 84.4 +/- 16.9 min in rabbits and 14.0 +/- 0.7 L/h, 9.2 +/- 10.1 L and 54.5 +/- 57.2 min in dogs, respectively. Based on animal data, human pharmacokinetic parameters of Cl, V ( ss ) and t (1/2) were predicted by simple allometry. In addition, actual concentration-time profiles obtained from animals were transformed to human profiles by species-invariant times of kallynochron, apolysichron and dienetichron. The predicted human pharmacokinetic parameters of Cl, V ( ss ) and t (1/2) by using simple allometry and species-invariant time transformation method ranged from 48.3-97.2 L/h, 49.1-92.9 L and 45.6-187.2 min, respectively. Those predicted parameters of oleanolic acid may be useful in designing dosing schedules of oleanolic acid in future clinical studies.

Abstract
This study was conducted to characterize the disposition, oral bioavailability, and tissue distribution of zearalenone in rats. The pharmacokinetics and tissue distribution of zearalenone were studied after intravenous (i.v.) or oral (p.o.) administration at doses ranging from 1 to 8 mg/kg in intact and bile duct-cannulated rats. Serum, bile, and urine concentrations were determined by liquid chromatography and mass spectroscopy (LC/MS/MS) and tissue concentrations by high-performance liquid chromatography (HPLC)/fluorescence detection assays. Noncompartmental methods were used for pharmacokinetic analysis. Average Cl(s) (range 5.0-6.6 L/h/kg) and V(dss) (range 2-4.7 L/kg) remained unaltered over an i.v. dose range from 1 to 8 mg/kg, and area under the concentration-time curve (AUC) and initial peak concentrations increased linearly with dose. Minimal quantities of zearalenone were excreted unchanged in urine (f(e,urine) 0.5 +/- 0.2%) and bile (f(e,bile) 0.91 +/- 0.64%). After p.o. administration of 8 mg/kg, zearalenone was rapidly absorbed and serum concentration-time profiles showed a distinct second peak. The absolute oral bioavailability was low (2.7%). Comparing bile duct-cannulated to intact rats at a dose of 8 mg/kg, the impact of biliary excretion on overall pharmacokinetics was more pronounced after p.o. than after i.v. administration. Upon i.v. infusion to steady state, the highest zearalenone concentration was found in small intestine, followed by kidneys, liver, adipose tissue, and lung. Zearalenone concentrations in stomach, heart, brain, spleen, muscle, and testes were lower than those found in serum. The pharmacokinetics and tissue distribution data from this study may be useful to develop physiologically based pharmacokinetic (PBPK) models for zearalenone and subsequently to predict the pharmacokinetics and toxicity in humans.

Abstract
The objectives of this study were to (1) develop physiologically based pharmacokinetic (PBPK) models for zearalenone following intravenous (i.v.) and oral (p.o.) dosing in rats and (2) predict concentrations in humans via interspecies scaling. The model for i.v. dosing consisted of vein, artery, lung, liver, spleen, kidneys, heart, testes, brain, muscle, adipose tissue, stomach, and small intestine. To describe the secondary peak phenomenon observed after p.o. administration, the absorption model was constructed to reflect glucuronidation, biliary excretion, enterohepatic recirculation, and fast and slow absorption processes from the lumenal compartment. The developed models adequately described observed concentration-time data in rats after i.v. or p.o. administration. Upon model validation in rats, steady-state zearalenone concentrations in blood and tissues were simulated for rats after once daily p.o. exposures (0.1 mg/kg/d). The average steady-state blood zearalenone concentration predicted in rat was 0.014 ng/ml. Subsequently, a daily human p.o. dose needed to achieve the same steady-state blood concentration found in rats (0.014 ng/ml) was determined to be 0.0312 mg/kg/d or 2.18 mg/70 kg/d. The steady-state zearalenone concentration-time profiles in blood and tissues were also simulated for human after multiple p.o. administrations (dose 0.0312 mg/kg/d). The developed PBPK models adequately described the pharmacokinetics in rats and may be useful in predicting human blood and tissue concentrations for zearalenone under different p,o, exposure conditions.

Abstract
This study was conducted to evaluate the pretreatment effects of different in vivo moxibustion on the permeation of a model high molecular compound, FITC-dextran, with a mean molecular weight of 4 kDa (FD-4), through excised hairless rat skin. Direct or indirect moxibustion (0.10 g moxa) was pretreated consecutively 4 times every 5 min on the abdomen of hairless rats, and the permeation of FD-4 was determined through the excised skin over 8h from 30 min after starting the first moxibustion. This consecutive moxibustion pretreatment showed a significant increase in the skin temperature as well as skin permeation of FD-4 compared with the control group (no moxibustion pretreatment). Quantitative parameters showed an increase in skin temperature and skin permeation: the area under the skin temperature over control temperature-time curve during one burning cycle (5.0 min) (AUCtemp) or the maximum skin temperature during moxibustion (Tmax) and the cumulative amount of FD-4 permeated through skin over 8h (Q8) or steady-state flux were increased by moxibustion pretreatment. Then, the effect of pedestal thickness (distance from the moxa cylinder and skin surface), shape of the moxa cylinder (5mm diameter, 13 mm height or 9 mm diameter, 7 mm height), burning materials (moxa or aromatic incense), pedestal component (paper, potato or ginger) and moxibustion pretreatment method (direct or indirect moxibustion) was evaluated on the AUCtemp or Tmax and Q8 or flux. The amount of protein leached from the skin surface was also determined as an inflammatory index by this moxibustion pretreatment. When the skin temperature was increased to 60 degrees C, the Q8 or flux as well as the amount of protein leached were markedly increased. When the skin temperature was controlled to 42 to 45 degrees C by an adequate selection of pedestal thickness, shape of the moxa cylinder, burning materials, pedestal component and moxibustion pretreatment method, on the other hand, protein leaching remained unaltered, but the Q8 or flux significantly increased with the Tmax. This study thus provides credible evidence that moxibustion pretreatment increases the skin permeation of high molecular compounds.

Abstract
This study examined the absorption and pharmacokinetic disposition of 125I-GST-TatdMt, a recombinant Tat protein possessing potent anti-obesity activity, in mice after vascular and extravascular administration. GST-TatdMt was over-expressed in E. coli, purified, and radioiodinated using the IODO-GEN method. 125I-GST-TatdMt was administered to mice by i.v., i.p. and oral administration at doses of 652.7 nCi (102.3 microg). Upon i.v. injection, the average terminal elimination half-life (t1/2,lambdaz), AUC and AUMC were 6.4 h, 318.2 nCixh/mL and 2518 nCixh2/ mL, respectively. The highest radioactivity was observed in lung followed by liver, spleen, heart and kidney. The t1/2lambdaz values obtained from i.v., i.p., and oral administration were comparable from each other (range 5.8-6.4 h). The absolute bioavailability of 125I-GST-TatdMt was 42.8% and 60.5% after p.o. and i.p. administration, respectively. Given the cell-penetrating nature, 125I-GST-TatdMt may be absorbed into the systemic circulation to a relatively high extent after extravascular administration.
