A three-month repeated oral administration study of a low viscosity grade of hydroxypropyl methylcellulose in rats. (1/429)

The toxicity of the lowest viscosity grade of hydroxypropyl methylcellulose (HPMC) that is currently commercially available was investigated by means of a three-month repeated oral administration study in male and female Crj:CD (SD) IGS rats at doses of 505, 1,020 and 2,100 mg/kg/day. Body weights of males and females in the 2,100 mg/kg group were lower than those of the control group on and after day 28 of administration, but the differences were not statistically significant. The degree of suppression of body weight gain in males was higher than that in females. This tendency was similar to the results in other toxicity studies of HPMC that have been reported. Males in the 2,100 mg/kg group showed a tendency (not significant) for decreased food consumption and urine volume. Examinations of general signs, hematology, blood chemistry, ophthalmology, absolute and relative organ weights, autopsy and histopathology revealed only a few, apparently coincidental, statistically significant differences from the control, and no evidence of any dose-dependent changes was found. It was concluded that the lowest viscosity grade of HPMC showed extremely low toxicity under the conditions of this study, as has been found for higher viscosity grades.  (+info)

Defining optimum conditions for the ex vivo expansion of human umbilical cord blood cells. Influences of progenitor enrichment, interference with feeder layers, early-acting cytokines and agitation of culture vessels. (2/429)

Ex vivo expansion of human umbilical cord blood cells (HUCBC) is explored by several investigators to enhance the repopulating potential of HUCBC. We performed experiments using either Ficoll-separated or CD34+-selected HUCBC from the same donation in serum-free medium. CD34-purified HUCBC were cultured on either human umbilical vein endothelial cells (HUVEC) or irradiated bone marrow-derived stroma cells (BMSC) with addition of different cytokines. In addition, we tested the expansion of HUCBC in culture vessels with continuous rotation. CD34 enrichment led to a significant increase in the expansion factor of CD34+ cells compared with unmanipulated HUCBC. BMSC were more efficient in amplifying early progenitors than HUVEC. Optimum results were reached by a combination of SCF, FLT-3L at 300 ng/ml and IL-3 at 50 ng/ml. No significant improvement in the expansion of CD34+/38- primitive progenitors could be obtained with other combinations. Addition of megakaryocyte-derived growth and development factor to each growth factor cocktail improved the expansion results. Continuous rotation of culture vessels did not ameliorate the expansion rate of the analyzed subsets. Culture conditions separating stroma and HUCBC by a semipermeable membrane improved the expansion factors of CD34+, CD34+/38-, and CD34+/41+ cells and CFU-GM compared with contact cultures. These data might be useful when designing culture systems for clinical scale ex vivo expansion of HUCBC.  (+info)

The evaluation of hypersensitivity tests in cattle after foot-and-mouth disease vaccination. (3/429)

The response to passive cutaneous anaphylaxis, dermal hypersensitivity and intravenous provocation tests has been compared in 30, 40, 31 and 24 cattle injected with foot-and-mouth disease vaccine 0, 1, 2 and 3 times respectively, using vaccine components and other substances as test materials. Reaginic antibodies demonstrated by passive cutaneous anaphylaxis in goats, were directed against BHK 21 cell extracts (20), hydroxypropylmethylcellulose (3) and an unidentified vaccine component (3), and distributed in 0, 5, 19 and 75 per cent of the cattle vaccinated 0, 1, 2 and 3 times. None of the animals showed clinical signs of allergy after vaccination. When BHK 21 cell extract was injected intradermally a significant correlation was noted between the development of large weals and the presence of reagins although the size of the weals was not correlated with the reagin titres. In the case of hydroxypropylmethylcellulose a similar trend was evident. The majority of cattle with large dermal weals possessed reagins but the number of reactions was too small for statistical evaluation. Dermal reactions to sodium penicillin, sodium carboxymethylcellulose, saponin and whole vaccine occurred in both unvaccinated and vaccinated cattle but BHK 21 cell lysate and normal bovine serum provoked weals which increased in frequency according to the number of vaccinations experienced. Intravenous hydroxypropylmethylcellulose elicited a response in all the animals previously injected with certain batches of vaccine but cell extract intravenously produced a clinical response in half the tested animals which was uncorrelated with the results of the passive cutaneous anaphylaxis or dermal hypersensitivity tests.  (+info)

Analysis of signals and functions of the chimeric human granulocyte-macrophage colony-stimulating factor receptor in BA/F3 cells and transgenic mice. (4/429)

Receptors for GM-CSF, IL-3, and IL-5 are composed of two subunits: alpha, which is specific for each cytokine, and betac, which is shared by all. Although the role of betac in signal transduction has been extensively studied, the role of the alpha subunit has remained to be clarified. To analyze the role of the human (h) GM-CSF receptor alpha subunit, we constructed a chimeric receptor subunit composed of extracellular and transmembrane regions of alpha fused with the cytoplasmic region of betac, designated alpha/beta. In BA/F3 cells, chimeric receptor composed of alpha/beta,beta can transduce signals for mitogen-activated protein kinase cascade activation and proliferation in response to hGM-CSF. Although phosphorylation of Jak1 but not of Jak2 occurred with stimulation of hGM-CSF, the dominant-negative Jak2 but not the dominant-negative Jak1 suppresses c-fos promoter activation. To determine whether the chimeric receptor alpha/beta,beta is functional in vivo, we developed transgenic mice expressing the chimeric receptor alpha/beta,beta. Bone marrow cells from the transgenic mice expressing the alpha/beta,beta receptor form not only GM colonies but also various lineages of colonies in response to GM-CSF. In addition, mast cells were produced when bone marrow cells of the transgenic mouse were cultured with hGM-CSF. Thus, it appears that the cytoplasmic region of the alpha subunit is not required for hGM-CSF promoting activities, even in bone marrow cells.  (+info)

High-molecular-weight hydroxypropylmethylcellulose taken with or between meals is hypocholesterolemic in adult men. (5/429)

Hydroxypropylmethylcellulose (HPMC) is a food gum that shares certain characteristics, such as high viscosity, with soluble fibers. In this trial, the safety and cholesterol-lowering efficacy of HPMC consumed with and between meals was evaluated in free-living male volunteers with mild-to-moderate hypercholesterolemia. After a 14-d baseline period, men (n = 51) with LDL cholesterol between 3.36 and 4.91 mmol/L and triglycerides <3.95 mmol/L were randomly assigned to consume 5.0 g/d HPMC in 240 mL of orange drink, taken either with or between meals, for a 2-wk treatment period. In the Between Meals group, total cholesterol was reduced by 8.0% vs. baseline in wk 1 of treatment (P < 0.05) and 5.1% in wk 2 (P < 0.01). LDL cholesterol concentrations fell by 12.0 and 7.7% (P < 0.01). In the With Meals group, reductions were 9.5 and 8.3% for total cholesterol, and 12.5 and 12.8% for LDL cholesterol (wk 1 and 2, respectively, P < 0.01). In both groups, HDL cholesterol decreased by approximately 5% during wk 1 of treatment (P < 0.01), but the wk 2 concentrations were not significantly different from baseline. There were no significant differences between groups in lipid responses, although there was a trend for a smaller LDL cholesterol-lowering effect during wk 2 of treatment in the Between Meals group (P < 0.06). Gastrointestinal-related adverse experiences (mostly mild) were twice as common among participants who ingested HPMC with meals (P < 0.05). These results suggest that HPMC has a lipid-lowering effect, which may be more consistent when taken with meals.  (+info)

Inhibition of keratinocyte apoptosis by IL-15: a new parameter in the pathogenesis of psoriasis? (6/429)

Keratinocytes (KC) are important source of and targets for several cytokines. Although KC express IL-15 mRNA, the functional effects of IL-15 on these epithelial cells remain to be dissected. Investigating primary human foreskin KC and HaCaT cells, we show here by semiquantitative RT-PCR and flow cytometric analysis that both translate IL-15 and IL-15R mRNA and express IL-15 and IL-15Ralpha protein on the cell surface, suggesting that human KC can employ IL-15 for juxtacrine signaling. While IL-15 exerted no significant effect on KC proliferation and IL-6 or IL-8 secretion, IL-15 inhibited both anti-Fas and methylcellulose-induced KC apoptosis in vitro. This is in line with the recognized potent anti-apoptotic effects of IL-15. IL-2, whose receptor shares two components with the IL-15R, failed to inhibit KC apoptosis. Together with the role of IL-15 in sustaining chronic immune reactions, this invited the question of whether a reduction of KC apoptosis by IL-15 may be involved in the pathogenesis of psoriasis, a chronic hyperproliferative inflammatory skin disease characterized by abnormally low KC apoptosis in the epidermis. Remarkably, compared with nonlesional psoriatic skin and skin of healthy volunteers, lesional psoriatic epidermis showed high IL-15 protein expression in the epidermis and enhanced binding activity for IL-15. Therefore, antagonizing the inhibitory effects of IL-15 on KC apoptosis deserves exploration as a novel therapeutic strategy in psoriasis management.  (+info)

Polymeric films as vehicle for buccal delivery: swelling, mechanical, and bioadhesive properties. (7/429)

PURPOSE: To investigate the suitability of an SCMC (sodium carboxymethyl cellulose/polyethylene glycol 400/carbopol 934P) and an HPMC (hydroxypropylmethyl cellulose/polyethylene glycol 400/carbopol 934P) films as drug vehicle for buccal delivery. METHODS: The mechanical and in vitro bioadhesive strength properties of the films were investigated using texture analyzer equipment, while swelling behavior was studied in different media, namely, distilled water and simulated saliva solution. In addition, the in vivo bioadhesion of the film was studied by estimating the film residence time on buccal mucosa of human volunteers. RESULTS: Increase in carbopol 934P content was found to elevate the elasticity, softness and bioadhesive strength but decrease the strength and degree of swelling of both SCMC and HPMC films. SCMC films swelled more extensively in distilled water while HPMC films in simulated saliva solution. HPMC films exhibited greater in vivo bioadhesion although the in vitro bioadhesive strength was lower than SCMC films. Correlation existed between the in vivo and in vitro bioadhesion data within the polymer, but no rank correlation was observed between the two polymers. CONCLUSION: HPMC films may be preferred over SCMC films as drug vehicle for buccal delivery as the former was tougher, more elastic, more bioadhesive in vivo and swelled in a more tolerable manner in the oral cavity than the latter.  (+info)

The instilled fluid dynamics and surface chemistry of polymers in the preocular tear film. (8/429)

Using slit lamp fluorophotometry it was demonstrated that the rate of drainage of a vehicle placed in the eye increased with increasing volume and that polymer solutions increased the thickness of the precorneal tear film (PTF). By increasing the viscosity of the delivery vehicle, (e.g., a hydroxypropylmethylcellulose polymer solutions), the PTF retention of fluorescein could be increased. The increased retention was shown to be due to an increase in the tear reservoir volume provided by the more viscous solutions. The PTF retention of fluorescein in a polyvinyl alcohol (PVA) vehicle was not as viscosity dependent, although PVA did seem to produce greater initial PTF fluorescence. This suggested that PVA initially produced a thicker PTF. The PTF retention of fluorescein by five commercial solutions did not have any relation to their wetting properties. The only good correlation with fluorescein retention in the PTF measured, seemed to be the ability of different polymer solutions to stabilize a thick layer of water as measured by the spontaneous spreading of polymer molecules at the air/liquid interface on wet glass surfaces. This model was designed to simulate tear film spreading in vivo. The results suggest that different polymer solutions may produce thicker PTF's than normal by virtue of their ability to drag water with them as they spread over the ocular surface with each blink. Mechanisms by which polymer solutions may increase the thickness of the PTF are discussed.  (+info)

Hypromellose solutions were patented as a semisynthetic substitute for tear-film.[8] Its molecular structure is predicated upon a base celluloid compound that is highly water-soluble. Post-application, celluloid attributes of good water solubility reportedly aid in visual clarity. When applied, a hypromellose solution acts to swell and absorb water, thereby expanding the thickness of the tear-film. Hypromellose augmentation therefore results in extended lubricant time presence on the cornea, which theoretically results in decreased eye irritation, especially in dry climates, home, or work environments.[9] On a molecular level, this polymer contains beta-linked D-glucose units that remain metabolically intact for days to weeks. On a manufacturing note, since hypromellose is a vegetarian substitute for gelatin, it is slightly more expensive to produce due to semisynthetic manufacturing processes. Aside from its widespread commercial and retail availability over the counter in a variety of ...

An increasing number of new chemical entities suffer from poor solubility in aqueous media making drug delivery via oral solid dosage form challenging. To address this issue, formulations are increasingly relying on the use of amorphous solid dispersions of the active with an excipient. The excipient serves the function of stabilizing the active as amorphous in the solid state and acts as a nucleation inhibitor upon dissolution. The use of spray drying is one of the leading technologies for this application space. Similarly, hypromellose acetate succinate (HPMCAS) is one of the leading excipients used in spray drying. Although extensively used in spray drying, little is understood about the affinity of organic solvents for the HPMCAS polymer. The affinity of the spray solvent for HPMCAS can impact drying rate, secondary drying rate (removal of residual solvent in a secondary batch process), and the glass transition temperature of the spray dried dispersion. The objective of this study was to ...

In this paper, the behavior of oxidized methylcelluloses is compared with that of the initial methylcellulose, an amphiphilic cellulose derivative. Methylcelluloses are important for many applications in the cosmetic and food industries. The mechanism of thermo-gelation of methylcellulose is briefly explained as well as the method of oxidation of polysaccharides. Then, our experiments involve the preparation of oxidized methylcelluloses: three degrees of oxidation are prepared and the new polymers are characterized by NMR, IR, SEC and rheology. Oxidation with periodate theoretically allows introduction of two aldehydic groups on C2-C3 glycol positions of anhydroglucose units. This reaction not only enhances the flexibility of the cellulosic backbone, but also causes a decrease in the molecular weight. In particular, the rheological behavior of methylcellulose and oxidized methylcellulose as a function of temperature is examined. The oxidized methylcelluloses prepared, being rich in aldehyde functions,

Here we describe a new high-resolution method for measuring and quantifying nanoparticles in suspension. It involves premixing nanoparticles in a hydrophilic support medium (methylcellulose) before introducing heavy metal stains for visualization in small air-dried droplets by transmission electron microscopy (TEM). The use of methylcellulose avoids artifacts of conventional negative stain-TEM by (1) restricting interactions between the nanoparticles, (2) inhibiting binding to the specimen support films and (3) reducing compression after drying. Methylcellulose embedment provides effective electron imaging of liposomes, nanodiscs and viruses as well as comprehensive visualization of nanoparticle populations in droplets of known size. These qualities facilitate unbiased sampling, rapid size measurement and estimation of nanoparticle ...

The purpose of this work was to develop extended-release matrix tablets of highly water-soluble alfuzosin hydrochloride using different viscosity grades of Hydrxy propyl methyl cellulose polymers by wet granulation method. The influence of three granulating fluids viz. water, dichloromethane: ethanol and isopropyl alcohol on release rate of alfuzosin hydrochloride were studied with a view to design and development of once daily formulations of alfuzosin hydrochloride. The tablets were analysed to determine their hardness, friability, drug content and an in vitro release study was carried out. The dissolution profile indicated that the drug release was found to be influenced by the polymer and granulating fluid employed in the formulation. Based on release rate the polymers can be rated as HPMC K100M > HPMC K15M> HPMC K4M. Based on the dissolution rate the granulating fluids can be rated as water>dichloromethane: ethanol> isopropyl alcohol. The dissolution profiles followed first order kinetics and the
