A novel and selective method for the fast determination of trace amounts of chromium species in water samples has been developed. The procedure is based on the selective formation of chromium diethyldithiocarbamate complexes at different pH in the presence of Mn（Ⅱ） as an enhancement agent of chromium signals followed by elution with organic eluents and determination by atomic flame absorption spectrometry. The maximum capacity of the employed disks was found to be （396±3） pg and （376±2） pg for Cr（Ⅲ） and Cr（Ⅵ）, respectively. The detection limit of the proposed method is 49 and 43 ng·L^-1 for Cr（Ⅲ） and Cr（Ⅵ）, respectively. The proposed method was successfully applied for determination of chromium species Cr（Ⅲ） and Cr（Ⅵ） in different water samples.

Mesoporous lanthanum phosphate was synthesized by supramolecular self-assembly of cetyltrimethylammonium bromide and lanthanum nitrate following digestion in phosphoric acid. TGA-DTA, XRD and SEM were employed to study the uncalcined and calcined materials. Sorption behavior of Cr（Ⅲ）, Mn（Ⅱ）, Fe（Ⅲ）, Co（Ⅱ）, Ni（Ⅱ）, Cu（Ⅱ）, Zn（Ⅱ）, Cd（Ⅱ）, Ba（Ⅱ）, Hg（Ⅱ） and Pb（Ⅱ） cations was studied on such materials in water, 3 mol·L^-1 ammonia, 0.01 mol·L^-1 potassium ferrocyanide and 0.01 mol·L^-1 potassium ferricyanide solutions.

AIM：（1） To gain information on immune responses to an accelerated schedule of 0, 1, and 2 mo in paramedical staff and BDS students who are at an increased risk of getting hepatitis B infection and come under high risk groups. （2） To assess the efficacy and safety of En/vac- HB in different age groups, using genetically modified yeast strain Pichia pastoris, a new recombinant hepatitis B accine developed and manufactured in India. METHODS： A prospective, comparative, and single blinded trial of rapid （0, 1, and 2 mo） hepatitis B immunization schedulewas reported. A total of three hundred and seven （212 females and 95 males） healthy volunteers divided into three age groups （18-29, 30-39, and 40-49） were enrolled after screening for markers of hepatitis B. All the volunteers received 20 mg of the vaccine intramuscularly at 0, 1, and 2 mo. RESULTS： Geometric mean titers were calculated pre and post vaccination. Before immunization the GMT was 0.0124 mIU/mL. One month after the administration of the third dose of recombinant vaccine 296/307 （96.5%） subjects achieved seroprotective levels of anti-HBs. The geometric mean anti-HBs titers achieved after one month of the third dose was 2 560.0 mIU/mL. The geometric mean anti-HBs titer of males was 2 029.0 mIU/mL, while that of the females was 2 759.0 mIU/mL. In the age group of 18-29 years, anti-HBs titer was 3 025.0 mIU/ mL, while that in the age group of 30-39 years was 2 096.0 mlU/mL. In third age group of 40-49 years, anti- HBs titer was 1 592.0 mIU/mL. Hyper-responses （anti-HBs≥100 mIU/mL） were shown in 88.0% （271/307） of subjects. Eleven （3.5%） subjects responded poorly to the vaccine in the age group of 40-49 years. There was only mild pain at the site of injection otherwise there were no other adverse drug reactions （ADRs）. CONCLUSION： This vaccine （Enivac-HB） is safe and efficacious, providing significant protection after the third dose and rapid hepatitis B immunization schedule of 0, 1, and 2 mo can be recommended

In this study, we developed a simple and sensitive HPLC method for the determination of lisinopril in human plasma. The sample clean-up was carried out by solid-phase extraction(SPE) using a cation-exchange(Strata-SCX~?) extraction cartridge. After a pre-column derivatization with 4-fluoro-7-nitro-2,1,3-benzoxadiazole, the reaction mixture was analyzed on an Agilent Zorbax SB~?-C_(18)(150 mm×4.6 mm, 5 μm). The flow rate was set at 1.0 mL/min. Fluorescence detection was performed at an excitation wavelength of 470 nm and an emission wavelength of 530 nm. The mobile phase consisted of a mixture of methanol and 0.02 M sodium dihydrogen phosphate(pH = 3.0, 60:40, v/v). The average extraction recovery of lisinopril and fluvoxamine(internal standard) was >85%. The method exhibited a linear calibration curve over the concentration range of 1–1000 ng/mL with a correlation coefficient(r^2) of ≥0.98 and a limit of quantification(LOQ) equal to 2 ng/mL. The within-run and between-run precisions were satisfactory with an RSD of 3.8%–13.7%(accuracy: from 95.0% to 96.4%) and 4.273%–14.3%(accuracy: from 94.4% to 98.5%), respectively.
