Abstract
Drug delivery to the brain is limited by the blood-brain barrier (BBB). Intranasal delivery is a non-invasive route of drug administration which can bypass the BBB and contributed to a direct and rapid transport of drugs to the brain. However, intrinsic drug distribution to the brain after intranasal administration may not be sufficient to achieve required clinical efficacy. In this study, taking 2,3,5,6-tetramethylpyrazine (TMPP) as a model drug, the feasibility of using polysorbate 80 as an absorption enhancer and message guider to increase drug distribution in the brain was employed. After intravenous/intranasal administration of TMPP formulations with/without polysorbate 80, drug concentration in both plasma and brain was measured at specific time points, and the pharmacokinetic parameters were compared. It was demonstrated that compared with intravenous administration, brain targeting efficiency of TMPP was improved remarkably by intranasal route. Upon intranasal administration, the addition of polysorbate 80 significantly increased TMPP concentration in both plasma and brain linearly up to polysorbate 80 concentration 2%. Based on drug targeting efficiency, drug targeting index, and nose-to-brain direct transport percentage, polysorbate 80 decreased the nose-to-brain direct transport ratio of TMPP in a polysorbate 80 concentration-dependent manner although the total brain targeting efficiency was unchanged, with significantly enhanced absolute drug concentration in the brain achieved. In summary, polysorbate 80 is a promising excipient to increase drug concentration in both plasma and brain via intranasal route.

Abstract
The low aqueous solubility of most hydrophobic medications limits their oral absorption. An approach to solve this problem is to make a drug-polymer association. Herein, we investigated the association between rafoxanide (RAF), a surface-active, poorly water-soluble drug, with a commercial hydrophilic polymer povidone. We found that the association is a function of medium composition and could only take place in polar media, such as water. The association is favored by the hydrogen-bond formation between the amide group in RAF and the carbonyl group in povidone. In addition, the association is also favored by the self-association of RAF through π-π interaction between the benzene rings in adjacent RAF molecules. Two-dimensional nuclear magnetic resonance has been applied to investigate the interactions and has confirmed our hypotheses. Geometry optimization confirmed that RAF exists primarily in the antiparallel configuration in the RAF aggregates. This study provides critical information for designing suitable drug-vehicle complexes and engineering the interactions between them to maximize the oral absorption. Our results shed light on drug design and delivery, drug molecule structure-functionality relationship, as well as efficacy enhancement toward interaction engineering.

Abstract
The use of multiple freeze (-20 degrees C)-thaw cycles in combination with isoeugenol and polysorbate 80 was investigated as a method for the reduction of numbers of Listeria monocytogenes cells in a bacteriological medium. Three freeze (1 h, -20 degrees C)-thaw cycles in the presence of isoeugenol at concentrations of 0, 100, and 300 ppm resulted in average L. monocytogenes reductions of 0.69, 2.65, and 3.3 log10 MPN (most probable number) per ml, respectively. Increasing the number of freeze-thaw cycles further decreased cell numbers, with reductions of nearly 5 log10 MPN/ml being obtained with six freeze-thaw cycles. Freeze-thaw cycles were effective in reducing cell numbers at isoeugenol concentrations down to 25 ppm. Rapid freezing rates with liquid nitrogen were found to be less effective in reducing numbers of L. monocytogenes cells. Two rapid freeze-thaw cycles in the presence of 100 ppm isoeugenol and polysorbate 80 resulted in a reduction of 1.45 log10 MPN/ml. Two freezing (-20 degrees C) cycles involving slow freezing and thawing rates with samples being held frozen for 6 h for each cycle resulted in reductions larger than those obtained with faster freezing rates. It was found that complete thawing in freeze-thaw cycles was not necessary to achieve bactericidal action. The application of multiple freeze-thaw cycles in combination with low concentrations of isoeugenol could effectively reduce numbers of L. monocytogenes cells in bacteriological media.

Abstract
Enhanced absorption of p-aminobenzoic acid (PABA) from the colon by polyoxyethylated nonionic surfactants was investigated using an in situ perfusion technique. The order of their absorption-enhancing effect was as follows: polyoxyethylene lauryl ether greater than polyoxyethylene sorbitan fatty acid esters approximately equal to polyoxyethylene fatty acid esters. The coexistence of calcium chloride in the perfusing solution caused a partial reverse in this enhancement. The calcium ion sequestration capacity of the surfactants was correlated with their ability to enhance colonic absorption of PABA. The findings suggest that calcium ion sequestration by the surfactants contributes to their enhancement of the colonic absorption of PABA.

Abstract
A study was conducted to determine if four surfactants can induce increased weight gain in the mouse. Basic-H, Triton X-100, Amway All Purpose Adjuvant and X-77 were put in water and fed to various groups of ICR 21 day old female mice for a period of 43 days. All the mice were clinically normal throughout the study period. Pathological examination of a random sample of the mice revealed no gross pathological changes. Similarly, histopathological examination of the lungs, livers and intestines did not reveal any visible lesions. Basic-H and Amway surfactants induced weight gain, though not significantly, better at 0.1% (V/V) concentration while X-77 and Triton X-100 induced weight gain better at 0.4% (V/V) concentration. Overall results show that none of the surfactants tested induced significant weight gain.

Abstract
The effect of the chelating agent edetate disodium on the integrity of the goldfish membrane was examined. The time to produce death in goldfish exposed to secobarbital sodium was used as a reflection of membrane integrity. Although a minimum edetate disodium concentration was necessary to induce alterations in integrity, no direct relationship between the effect and concentration of the chelating agent was evident. The chelating agent's effect appeared to be an enhancement of the transport of the ionized drug form. The change in membrane integrity existed at least 24 hr after theoretical exposure to edetate disodium, but cyclic alterations in integrity could not be ruled out. The effect on integrity was also demonstrated to be nonpermanent, and the apparent loss in integrity was partially restored by calcium byt not by magnesium.

Abstract
The death times of goldfish have been measured in aqueous solutions containing different concentrations of p-substituted acetanilides alone or in the presence of poloxamers. Plots of reciprocal death time versus concentration were linear with a positive concentration intercept, the minimum effective concentration (MEC). The MEC values were directly related to the pi value (hydrophobic-lipophilic constant) of the functional group on the acetanilide indicating that activity is directly related to lipophilicity. Slopes of reciprocal death time versus drug concentration were linearly related to pi values but there was no direct dependence. The presence of poloxamers in aqueous acetanilide solutions reduced the goldfish death time. The effect of the poloxamers is believed to be one of rendering the goldfish membrane more permeable to drugs.

Abstract
Low concentrations of a polyoxyethylene detergent, Brij 58, inhibited the secondary phase of platelet aggregation induced by ADP in human citrated platelet-rich plasma but had no effect on primary aggregation. Thrombin-induced aggregation of washed human platelets suspended in Tyrode's buffer was inhibited after incubation of cells with 4.10(-6) M detergent. Efflux of [14C]serotonin, 45Ca2+ and labile aorta contracting substance (thromboxane A2) and development of prothrombin-converting activity (platelet factor 3) were abolished concomitantly. Aggregation of washed platelets either by sodium arachidonate or by collagen was also inhibited by the same concentration of Brij 58 which inhibited thrombin aggregation. This concentration did not itself produce any release of a cytoplasmic marker, lactate dehydrogenase, from platelets. Higher concentrations of Brij 58, exceeding 4.10(-5) M, lysed the cells liberating lactate dehydrogenase, serotonin and Ca2+. When albumin was included as a platelet stabilizer in the suspending medium the concentration of detergent required for the inhibitory effects was increased ten-fold. This could be attributed to competitive binding of the detergent to albumin, demonstrated with [14C]acetylated Brij 58. A variety of other polyoxyethylene detergents, at concentrations from 8.10(-4) to 5.10(-3) M, also inhibited platelet aggregation induced by thrombin. It is concluded that low concentrations of Brij 58 stabilize the platelets against the action of aggregating agents, while higher concentrations produce membrane destabilization and cell lysis.

Abstract
The distribution of a solubilizate between micelles and the aqueous phase does not obey a simple partition law when a second solubilizate species is present. Alterations of the apparent partition coefficient cannot be explained in terms of a simple displacement mechanism, following the interaction of both solubilizates with the same site of the micelle. A non linear increase in solubilizate association to micelles following an increase in surfactant concentration is observed in the presence of a second solubilizate. A depression in the cloud point temperature follows the addition of a second species and is such that cannot be interpreted as a simple additive effect. Alteration of the apparent partition coefficient in a miscellar solution has an effect on the permeation rate of the solubilizate across an artificial membrane. Biopharmaceutical implications are discussed.

Abstract
The goldfish has been used as a model membrane to estimate the absorption of quinalbarbitone sodium by measurement of overturn time. The effect of sodium cholate, sodium deoxycholate, sodium chenodeoxycholate and sodium taurodeoxycholate on the quinalbarbitone-induced overturn time has been investigated and differences in capacity to promote absorption have been demonstrated. These differences could not be attributed to variations in solubility or partitioning of the drug within the membrane by the bile salts or to the relative hydrophobicity of each molecule. It is suggested that the bile salts must in someway affect the integrity of the goldfish membrane rendering it more permeable to quinalbarbitone sodium.

Abstract
The influence of dioctyl sodium sulfosuccinate and poloxalene on the GI absorption of phenolsulfonphthalein in the rat was studied. Urinary excretion data after oral administration of the drug to intact rats and loss of the drug from the whole small intestine as a loop were both utilized to assess the effect of the surfactants on absorption. Dioctyl sodium sulfosuccinate markedly increased the absorption of the drug, and the extent was dependent on the surfactant concentration. Maximum effect was observed at the reported ED50 in rats, of the surfactant as a fecal softener. The mechanism responsible for absorption enhancement seems to be an alteration of the permeability of the intestinal membrane. Micellar complexation between the drug and the surfactant resulted in a lesser increase in absorption at the higher surfactant concentrations. Poloxalene did not increase drug absorption, but higher concentrations caused a decrease in absorption due to micellar entrapments of the drug molecules. The influence of dioctyl sodium sulfosuccinate on the peritoneal absorption of the drug was also investigated. Lower doses of the surfactant increased absorption of the drug by altering the membrane permeability. Higher doses decreased absorption due to unavailability of the drug molecules entrapped in the micelles.

Abstract
Polysorbate 80, which has been widely used in studies of the effects of surfactants on drug absorption, increases the rate of absorption of some drugs at concentrations near its critical micelle concentration (cmc). To determine whether all non-ionic surfactants were capable of inducing this effect, the effects of six commercial non-ionic surfactants on thioridazine absorption in goldfish have been compared with the effect of polysorbate 80. The reciprocal death time (T-1) determined when the fish were immersed in the solution under study was the index of absoprtion rate used. Not all surfactants tested increased T-1. Cremophor EL (polyoxyethylated castor oil), Atlas G1295 (a polyoxyethylene fatty glyceride), Atlas G1300 (a polyoxyethylene glyceride ester) had no effect below their cmc's. Those surfactants that did increase T-1 [polysorbate 80 (a polyoxyethylene lanolin derivative), G2162 (a polyoxyethylene oxypropylene monosterate) and Renex 650 (a polyoxyethylene alkyl aryl ether)] display the concentration-dependent behaviour reported previously - a decrease in absorption rate when the surfactant concentration is increased above its cmc. The factor determining whether or not the surfactant will increas absorption rate appears to be the configuration of the surfactant molecule rather than its hydrophile-lipophile balance or its surface activity.

Abstract
Abstract
The effect of a non-ionic surfactant, polysorbate 80, on the biological activity of chlorpromazine hydrochloride in solution was investigated using the goldfish, Carassius auratus. Below a certain critical concentration the activity was enhanced in unbuffered drug solutions, but above this concentration the activity was diminished, possibly due to some association between surfactant micelles and drug molecules. The rate of solution of chlorpromazine hydrochloride from coated tablets was increased by 2% polysorbate 80, but the activity was decreased when compared with that in a simple aqueous dissolution medium. This is direct evidence of the erroneous conclusions that can be obtained if dissolution measurements alone are used in assessing the effect of additives on drug performance.
