A new capillary coated by double polymer, polybrene/chondroitin sulfate C (P/CC), was developed using a simple procedure. The P/CC double coated capillary showed long lifetime, strong chemical stability and good reproducibility. It endured during more than 100 replicated analyses and was also tolerant to HCl (1 mol/L), NaOH (0.01 mol/L), CH3OH and CH3CN. The P/CC double coated capillary can be applied to basic drug analyses. The adsorption of basic drugs to the capillary wall was suppressed and the peak tailing greatly decreased. The use of the P/CC double coated capillary allowed excellent separation of the enantiomers of some basic drugs by using chondroitin sulfate C as the chiral selector, and the peak symmetry of basic drugs was further improved under these conditions.

Open Journal of Obstetrics and Gynecology 2013年第5期3卷 445-447页

malignant spinal cord compression (mSCC) rarely presents in patients with endometrial cancer. It usually occurs months or years after the diagnosis of the primary tumor. A 65-year-old woman presented with a huge uterine tumor suspecting leiomyosarcoma. She underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. Histopathological examination revealed mixed carcinoma (small cell carcinoma and endometrioid adenocarcinoma) of the endometrium. She presented with upper abdominal pain, back pain, cystoplegia and paraplegia of lower extremities postoperatively. magnetic resonance imaging revealed bone metastasis with destruction of the eighth thoracic vertebral body as the sites of metastasis. Vertebrectomy and irradiation therapy were performed for the lesion. Although she received systemic chemotherapy consisting of paclitaxel and carboplatin, she died 4 months after hysterectomy.

We have investigated the morphology of novel 3, 4-bis-alkyloxycarbonyl-hexanedioic acid monolayer (alkyl chain number n = 12, 14, and 16) formed on the water surface by dropping method using Surface Tension measurement (STm) and Brewster Angle microscopy (BAm). Surfactant of 3, 4-bis-alkyloxycarbonyl-hexanedioic acid has a gemini type structure. π-A isotherm curves (STm) of two gemini surfactants of n = 12 and 14 showed gradual increase in surface pressure, while that of n = 16 showed gradual increase, a stagnant range and finally steep increase. BAm observation showed each image corresponding to the result of STm measurement. From STm and BAm results of surfactants, it is found that surfactant of n = 12 and 14 form Liquid-Expand (LE) type monolayer, while that of n = 16 formed Liquid-Condensed (LC) type monolayer including LE-LC phase transition.

We have synthesized first novel dihexadecyl phosphate (DHGP-n) gemini surfactants containing alkyl chain ((CnH2n);n = 3, 4, 5, and 6) spacers. Surfactants were used to form monolayers on water surface. Surface tension measurement (STm), Brewster angle microscopy (BAm), and density functional theory (DFT) calculation were used to investigate these monolayers. Surface pressure (π) and molecular area (A);π-A isotherm curves of all DHGP-n gemini surfactants showed a gradual increase in surface pressure without any break points in the curves, confirmed the formation of liquid-expand (LE) type monolayers. BAm observations also supported the STm results. Limited molecular area (A0) of these monolayers depended on the spacer of gemini surfactants without spacer n = 4. Longer alkyl chain spacer in the series had higher value of A0 in π-A isotherm plots. In the series, A0 of spacer n = 4 was smallest among A0 values of other spacers. Density functional theory (DFT) method calculation also confirmed π-A isotherm curves pattern of these surfactants. Calculation showed that both odd and even numbers and length of the alkyl chain spacer influenced the structure of DHGP-n monolayer formation on the water surface.

We have investigated the morphology of dimyristoyl phosphatidyl choline (DmPC)—cholesterol mixed monolayer formed on the water surface by dropping method using surface tension measurement (STm), Brewster angle microscopy (BAm), and infrared external reflection spectroscopy (IERS). STm results showed negative deviation of the limiting molecular area (A0) of cholesterol occurred when cholesterol was added to the DmPC monolayer. BAm images showed the expandable DmPC monolayer changed to the condensed rigid monolayer at more than cholesterol mole fraction (xChol) 0.4. IERS recordings showed that the addition of cholesterol at xChol = 0.4 occurred structural change from gauche- to trans- conformation of two DmPC molecule alkyl chains. From these results, it is found that cholesterol molecule has specific properties that cause structural transition of DmPC molecule alkyl chains.

Compounds for a series of alkyltrimethylammonium salicylates (C12TA-Sal through C16TA-Sal) were synthesized. Their physical properties in aqueous solutions were investigated by conductometry, viscometry, vortex inhibition, viscoelastic recoil and swirling decay time from a view point of drag reduction. For critical micelle concentrations (CmC) obtained for a series of compounds by conductometry, it was found that a linear relation of the form, log(CmC)= 4.088﹣0.305*Nc (Nc: carbon number in the alkyl chain), holds. From the viscosity measurement, all the compounds showed viscosity increase above their CmC. Vortex inhibition was observed above the CmC for the compounds with the chain length longer than C13. Viscoelastic recoil was observed above the concentration of one and a half times the CmC for the compounds with alkyl chain length longer than C14.
