Comprehensive analysis of the substituent distribution in the glucosyl units and along the polymer chain of hydroxyethylmethyl celluloses and statistical evaluation.
Anal. Chem. 78(4) , 1146-57, (2006) Hydroxyethylmethyl celluloses (HEMC, DS(Me) 1.46-1.66, DS(HE) = 0.14-0.17) have been analyzed with respect to their methyl and hydroxyethyl pattern in the glucosyl units and along the polymer chain. Methyl groups were located by GLC/MS after direct hydrolysis... |

A study on the stability of prostaglandin E2 in methylhydroxyethylcellulose gel by gas chromatography.
J. Clin. Hosp. Pharm. 7(1) , 67-70, (1982) A method is reported for the analysis of prostaglandin PGE2 in methylhydroxyethylcellulose gel. Stability studies using the method have shown that the degradation of PGE in the gel is a first order process at 4 degrees and 25 degrees C. Five per cent breakdow... |

Comparative evaluation of the hypolipidemic effects of hydroxyethyl methylcellulose (HEMC) and hydroxypropyl methylcellulose (HPMC) in high fat-fed mice.
Food Chem. Toxicol. 50(2) , 130-4, (2012) The effect of hydroxyethyl methylcellulose (HEMC), in comparison with hydroxypropyl methylcellulose (HPMC), on the body weight and lipid metabolism in mice fed with high fat diet was investigated. The animals were given normal control diet (NC group), high fa... |

Hypoglycemic and antioxidative effects of hydroxyethyl methylcellulose in mice fed with high fat diet.
Food Chem. Toxicol. 50(5) , 1716-21, (2012) The effect of hydroxyethyl methylcellulose (HEMC) with different viscosities on the glucose metabolism and antioxidative defense system in high fat-fed mice was investigated. The mice were randomly divided into five dietary groups: normal control diet (NC), h... |
