AIMTo establish chiral separation method for donepezil hydrochloride (E2020) enantiomers by capillary electrophoresis (CE) and determine the two enantiomers in plasma.

METHODSAlkalized plasma was extracted by isopropanol-n-hexane (3 : 97) and L-butefeina was used as the internal standard. Enantioresolution was achieved using 2.5% sulfated-beta-cyclodextrin as chiral selector in 25 mmol x L(-1) triethylammonium phosphate solution (pH 2.5) on the uncoated fused-silica capillary column (70 cm x 50 microm ID). The feasibility of the method to be used as quantitation of E2020 enantiomers in rabbit plasma was also investigated.

RESULTSE2020 enantiomers were separated at a baseline level under the above condition. The linearity of the response was evaluated in the concentration range from 0.1 to 5 mg x L(-1). The linear regression analysis obtained by plotting the peak area ratio (A(s)/A(i)) of the analyte to the internal standard versus the concentration (C) showed excellent correlation coefficient (r = 0.999 2 for R(-)-E2020, r = 0.999 7 for S(+)-E2020) and the equations were A(s)/A(i) = 0.024 2 + 0.289 2C and A(s)/A(i) = 0.010 8 + 0.273 7C, respectively. The low limit of detection was 0.05 mg x L(_1). The inter- and intra-day precision (RSD) were all less than 20% .

CONCLUSIONCompared with CSP by HPLC, the CE method is simple, reliable, inexpensive and suitable for studying the stereoseletive pharmacokinetics in rabbits.

Objective To determine the effects of gutter oil on liver function,renal function and serum lipid metabolism in mice.Methods A total of 72 mice were averagely divided into 6 groups.Mice were gavaged with different dosages (5 μL/g,1 0 μL/g and 20 μL/g)of gutter oil or cooking oil every other day for continuing 8 weeks.The indexes of liver, kidney and serum lipid parameters were assayed.Results The moisture,acid value and peroxide value of the gutter oil exceeded the national standard.After continuing 8 weeks'intake of oils,alanine aminotransferase (ALT)of gutter oil group with a dosage of 5 μL/g,as well as aspartate aminotransferase (AST)of gutter oil group with a dosage of 1 0 μL/g significantly increased (P <0.05),compared with the cooking oil group.Serum creatinine (Scr)of the gutter oil groups with 3 dosages significantly increased compared with the control groups (P <0.05 ).Meanwhile,blood urea nitrogen (BUN)of gutter oil groups with a dosage of 5 μL/g and 1 0 μL/g were also significantly increased respectively(P <0.05). However,no significant differences were observed in triglyceride (TG)and total cholesterol (TC)among the groups. Conclusion Eight weeks'intake of gutter oil could cause the damage to liver and renal functions.

AIMTo establish a sensitive and specific liquid chromatography-mass spectrometry (time-of-flight) [LC-MS (TOF)] method for the determination of donepezil in human plasma after an oral administration of 5 mg donepezil hydrochloride tablet.

METHODSAlkalized plasma was extracted with isopropanol-n-hexane (3:97) and loratadine was used as internal standard. Solutes were separated on a C18 column with a mobile phase of methanol-acetate buffer (pH 4.0) (80:20). Detection was performed on a time-of-flight mass spectrometry equipped with an ESI interface and operated in positive-ionization mode. Donepezil quantitation was realized by computing the peak area ratio (donepezil-loratadine) (donepezil m/z 380[M + H]+ and loratadine m/z 383[M + H]+) and comparing them with calibration curve (r = 0.9998).

RESULTSThe linear calibration curve was obtained in the concentration range of 0.1-15 micrograms.L-1. The detection limit of donepezil was 0.1 microgram.L-1. The average recovery was more than 90%. The intra- and inter-run precision was measured to be below 15% of RSD.

CONCLUSIONThe method is sensitive, simple and rapid, so, it can meet the need of the studies on the pharmacokinetics and bioavailability of donepezil.

This study was aimed to explore the expression of B cell-activating factor of TNF family (BAFF) and B cell lymphoma/leukemia-2 (BCL-2) in bone marrow mononuclear cells (BMMNC) of multiple myeloma (MM) and the significance of BAFF and BCL-2 for occurrence, development and prognosis of MM. The bone marrow of 40 cases of MM and 10 healthy persons was collected, the mononuclear cells (MNC) were isolated, the expression of BAFF and BCL-2 mRNA in BMMNC was detected by real-time PCR; the plasma was simultaneously collected and the β2-MG level was determined; the clinical staging of MM patients was performed according to Durie-Salmon (D-S) staging criterion. The results indicated that the expression level of BAFF and BCL-2 mRNA in MM patients increased, as compared with normal controls, the difference was statistical significant (p < 0.05); the expression level of BAFF and BCL-2 mRNA in plateau stage after treatment obviously decreased. The expression level of BAFF and BCL-2 mRNA in relapsed/refractory MM patients was significantly higher than that in normal controls and patients reached plateau stage (p < 0.05), there was no statistically significant difference between newly diagnosed and relapsed/refractory MM patients (p > 0.05). The expression of BAFF and BCL-2 mRNA related with D-S staging and β2-MG level. It is concluded that the expression levels of BAFF and BCL-2 mRNA increase, moreover the expression levels of BAFF and BCL-2 mRNA in newly diagnosed and relapsed/refractory MM patients are higher than those in patients reached plateau stage, which suggest the BAFF and BCL-2 may be involved in occurrence and development of MM; the relation of expression level of BAFF and BCL-2 mRNA to MM load is positive, which indicates the expression level of BAFF and BCL-2 mRNA may be a new indicator for evaluating the prognosis of MM patients.
