Agricultural Sciences in China 2010年第3期9卷 449-456页

In this article, in vitro adsorption of aflatoxin B1 （AFB1） onto different adsorbents was characterized and the result was verified by comparing the growth performance and serum protein levels of broilers exposed to aflatoxin-contamination feed. Main components of adsorbents selected were yeast cell extracts （Product A）, HSCAS （Product B）, and a mixture of yeast product and HSCAS （Product C）, respectively. A total of 240 broilers were assigned to eight treatments, and the effects of three types of adsorbents on growth performance and serum protein levels were evaluated. Results indicated that Product B had the highest in vitro affinity for AFB1, followed by Product C and Product A. Product B bound 97.69% of the AFB1 in solution in 10 min, and it remained over 96.03% in 60 min at pH 8.0. The B-AFB1 complex was much stronger than the other two complexes in vitro condition （P 〈 0.05）. Feed intake （FI） and average daily gain （ADG） decreased （P 〈 0.05） and feed gain ratio increased （P 〈0.05） in the treatment fed aflatoxin-contaminated feed versus treatment on the basal feed. Serum total protein （TP）, albumin （ALB）, and globulin （GLOB） levels were significantly decreased （P〈0.05）. Product B （0.15%） increased growth performance and improved serum protein levels, Product A and Product C were not as effective as Product B. Three adsorbents tested here had sufficient potential to AFBt in some extents and Product B could bind AFB1 more effectively than Product A and Product C. These results indicated that Product B could alleviate some of the AFBt toxic effect in broilers.

Two charge qubits being coupled to a damped cavity with different couplings are considered. The dynamical evolution of the entanglement between the two qubits is demonstrated analytically or numerically. It is found that with the cavity dissipation, the steady entanglement between the two qubits can be achieved. The two qubits being initially in the separable and most mixed state can be easily induced to a steady entangled state, and the relative difference of the couplings can be used to enhance the steady entanglement between the two charge qubits.

The present study was designed to improve storage stability and oral bioavailability of Ganneng dropping pills(GNDP) by transforming lignans of Herpetospermum caudigerum(HL) composed of herpetrione(HPE) and herpetin(HPN) into nanosuspension(HL-NS), the main active ingredient of GNDP, HL-NS was prepared by high pressure homogenization and lyophilized to transform into solid nanoparticles(HL nanoparticles), and then the formulated HL nanoparticles were perfused into matrix to obtain NS-GNDP by melting method. For a period of 3 months, the content uniformity, storage stability and pharmacokinetics test in vivo of NS-GNDP were evaluated and compared with regular GNDP at room temperature. The results demonstrated that uniformity of dosage units of NS-GNDP was acceptable according to the criteria of Chinese Pharmacopoeia 2015 J. Physical stability of NS-GNDP was investigated systemically using photon correlation spectroscopy(PCS), zeta potential measurement, and scanning electron microscopy(SEM). There was a slight increase in particles and PI of HL-NS re-dispersed from NS-GNDP after storage for 3 months, compared with new formulated NS-GNDP, which indicated a good redispersibility of the NS-GNDP containing HL-NS after storage. Besides, chemical stability of NS-GNDP was studied and the results revealed that HPE and HPN degradation was less when compared with that of GNDP, providing more than 99% of drug residue after storage for 3 months. In the dissolution test in vitro, NS-GNDP remarkably exhibited an increased dissolution velocity compared with GNDP and no distinct dissolution difference existed within 3 months. The pharmacokinetic study showed that HPE and HPN in NS-GNDP exhibited a significant increase in AUC0–t, Cmax and decrease in Tmax when compared with regular GNDP. These results indicated that NS-GNDP possessed superiority with improved storage stability and increased dissolution rate and oral bioavailability.
