Two hybridoma cell lines 1B5 and 2F1 capable of secreting specific monoclonal antibodies (McAbs) against aflatoxin B1 (AFT B1) were obtained. BALB/c mice were immunized by intrasplenic injection of AFT B1-human serum albumin conjugate (AFT B1-HSA) containing 9 AFT B1 residue per molecule. Spleen cells of BALB/c mouse with high serum antibody titer were fused with SP 2/0 myeloma cells in the presence of polyethylene glycol. Hybridoma cell lines were selected by using an indirect ELISA with AFT B1-keyhole limpet haemocyanin as coating antigen and grown as ascite tumour cells in BALB/c mice which previously had received an intraperitoneal injection with Freund's incomplete adjuvant. The McAbs were found to have strong reaction with AFT B1-bovine serum albumin conjugate (AFT B1-BSA) and no reaction with HSA or BSA. The reactivity of the McAbs with AFT analogs was determined by an indirect inhibition ELISA and the concentrations (ng/ml) required to inhibit 50 binding of McAb to AFT B1-BSA conjugate solid phase were AFT B1 4.0ng/ml, B2 36.9ng/ml, G1 23.3ng/ml and G2 403.3ng/ml for 1B5 McAb, and AFT B1 2.4ng/ml, B2 2.6ng/ml, G1 2.8ng/ml and G2 4.7ng/ml for 2F1 McAb.

The objective of this study was to evaluate the left ventricular function after mitral valve replacement (MVR) with preservation of all chordae. Fourteen patients with a diagnosis of mitral regurgitation were studied. These patients, 4 males and 10 females, age from 24 to 59 years, who underwent mitral valve replacement, in which all chordae tendineae were preserved. The mean follow-up interval was 6 months. Preoperation and postoperation multigated equilibrium radionuclide angiography was performed by Elscint Helix Apex SPECT. Each patient was injected with 740MBq 99mTc-HSA, rest ejection fraction (global EF) of LV (%), regional ejection fraction (EF) of LV (%), PER/S and PFR/S were measured. Regional EF was calculated by the method of dividing the left ventricle into five segments by radial axis. The results showed that the postoperative EF of the whole left ventricle of the chordae-preserved patients was significantly greater than their preoperative EF (40.0% +/- 17.8%, to 51.6% +/- 18.2%, P < 0.02), and also the regional EF at the lateral wall of the chordae-preserved MVR was significantly greater than the preoperative regional EF (an increase from 51.0% +/- 18.1% to 69.7% +/- 21.2%, P < 0.01). MVR with preservation of all chordae, the patient's left ventricular function remarkably improved.
