Abstract
The purpose of this study was to estimate the selenium (Se) requirement of egg-laying ducks based on daily egg production and the selenoprotein glutathione peroxidase (Gpx). Five-hundred and forty laying ducks were divided into six treatments, each containing six replicates of 15 ducks. The birds were caged individually and received a Se-deficient basal diet (0.04 mg/kg) or diets supplemented with 0.08, 0.16, 0.24, 0.32, 0.40 mg/kg Se (as sodium selenite) for 6 months. The experiment consisted of two periods: an early-laying period of 2 months and the peak-laying period of 4 months. Egg production and feed intake were recorded daily. At the end of the experiment, blood samples were drawn for determination of Gpx activity in plasma (Gpx3) and in erythrocytes (Gpx1). Hepatic Gpx1 activity and relative expression of Gpx1 mRNA were also determined. Eggs (n = 6) were sampled for quality determination and Se content at the end of the experiment. The activities of plasma Gpx3, erythrocyte Gpx1 and liver Gpx1 increased in a quadratic manner (P < 0.001) with increasing supplemental Se. The mRNA abundance of hepatic Gpx1 increased linearly (P < 0.001) with dietary Se supplementation. Egg shell thickness was significantly reduced in the ducks fed 0.44 mg Se/kg (P < 0.05), indicating that higher dietary Se tends to compromise egg shell quality. Yolk and albumen contents of Se increased linearly (P < 0.0001) with dietary Se supplementation. Using quadratic broken line models, the Se requirement for daily egg production was 0.18 mg/kg for early-laying ducks and 0.24 mg/kg for peak-laying ducks; for optimal function of Gpx (peak-laying ducks), it was 0.37 mg Se/kg.

Abstract
To investigate the effects of a synthetic soybean isoflavone (ISF) on growth performance, meat quality, and antioxidation in male broilers, 1,500 birds that were 42 d old were allotted to 5 treatments with 6 replicates per treatment (50 birds per replicate). Birds were fed diets supplemented with 0, 10, 20, 40, or 80 mg of ISF/kg, respectively, for a period of 3 wk ad libitum. The results showed that dietary supplementations with 10 or 20 mg of ISF/kg increased weight gain by 13.6 and 16.2% (P < 0.01) and elevated feed intake by 7.37% (P < 0.05) and 11.2% (P < 0.01), respectively. Addition of 10 mg of ISF/kg decreased feed:gain by 5.5% (P < 0.05). Supplementation with 40 mg of ISF/kg in the diet slightly increased water-holding capacity by 17.24% (P < 0.1), and the addition of 20 or 40 mg/kg of ISF significantly increased the pH value of meat (P < 0.01), although adding 40 or 80 mg of ISF/kg increased the lightness of meat color (P < 0.05). Malondialdehyde production was slightly reduced in plasma of 20 mg of ISF/kg supplemented chickens (P < 0.1) and significantly decreased in breast muscles of 20, 40, or 80 mg of ISF/kg supplemented chickens (P < 0.01). The addition of 40 or 80 mg of ISF/kg significantly increased total antioxidant capability (P < 0.01) and slightly elevated total superoxide dismutase activity (P < 0.1) in plasma of chickens. The dose of 80 mg of ISF/kg slightly improved catalase activity in plasma (P < 0.06). In breast muscle, treatment of birds with 40 or 80 mg of ISF/kg caused an increase of total superoxide dismutase activity by 25.36% (P < 0.05) or 63.93% (P < 0.01). Catalase activity significantly increased by 70.61% by the supplemental ISF at the 40-mg level (P < 0.05). Also, 10, 20, or 40 mg doses of ISF/kg decreased lactic acid production (P < 0.05). The results of this study indicate that dietary ISF could improve growth performance and meat quality by decreasing lipid peroxidation and improving antioxidative status in male broilers.

Abstract
A new peptide named Martentoxin I and an analogue Martentoxin were purified and characterized from the venom of Buthus martensi Karch. Martentoxin I consisted of 36 amino acid residues with molecular mass as 3908.0 Da determined by matrix-assisted laser desorption ionization time-of-flight-MS. The amino acid sequence was determined as GLIDVKCFASSECWTACKKVTGSGQGKCQNNQCRCY by Edman degradation. Martentoxin consisted of 37 amino acid residues with a molecular mass as 4055.3 Da and it showed highly sequence identity to Martentoxin I as FGLIDVKCFASSECWTACKKVTGSGQGKCQNNQCRCY. Estimation from circular dichroism spectra indicated Martentoxin I owned 18.0% alpha-helix, 53.0% beta-sheet structure and 3.9% turn while Martentoxin contained 13.3% alpha-helix, 64.3% beta-sheet structure and 1.1% turn. The toxicity assay showed both peptides had no toxic effects on mice up to the dose of 10 mg/kg. Electrophysiological studies showed that Martentoxin I and Martentoxin at the concentration of 1 microm significantly inhibited voltage-dependent Na+ current (INa) and voltage-dependent delayed rectifier K+ current (IK) but had no effects on transient K+ current (IA). Both interactions with Na+ and K+ channels were irreversible.

Abstract
Further studies on the roots of Goniothalamus donnaiensis Finet et Gagnap (Annonaceae) led to the isolation of two pairs of Annonaceous acetogenins, donnaienin C ( 1) and 34- EPI-donnaienin C ( 1'), donnaienin D ( 2) and 34- EPI-donnaienin D ( 2'), containing a rare gamma-hydroxymethyl-gamma-lactone moiety and a C-4-acetoxy group. Their structures were elucidated by spectral data and chemical derivatization. Preliminary pharmacological tests showed that the mixture of donnaienin C( 1) and 34- EPI-donnaienin C ( 1') inhibited human hepatoma (Bel) cell lines in vitro (IC (50), 7.1 microg/ml).

On the basis of spectral and chemical evidence, auriculatusaponins A, B, and C were determined as 3beta- O-beta-glucuronyl-16-oxo-12-ene-28-noroleanane, 3beta- O-beta-glucuronyl-16alpha- trans-feruloyloxy-12-en-oleanane, and 3- O-beta-glucopyranosyl-16alpha-hydroxy-olean-12-ene-28-oic acid 28- O-carboxymethyl ester, respectively.

Abstract
The total synthesis of cimicifugamide, a new natural compound isolated from the roots of Cimicifuga dahurica, was accomplished by a reaction sequence of seven steps in an overall yield of 31%. Trifluoroacetoxy was used as leaving group at the anomeric carbon. The target product was characterized by IR, MS, 1HNMR, 13CNMR and elemental analysis. In addition, seven analogues were synthesized and their preliminary pharmacological activities were tested.

Abstract
S-( -- )-Ligustiphenol is a new sesquiterpene with anti-inflammatory and immunosuppressive activities. In order to study its pharmacological activities, the total synthesis of its racemat was carried out by a six-step reaction sequence including bromination of aldehyde, iodination of m - cresol, protection of phenolic hydroxyl, Grignard reaction, Aldol condensation, etc. The target compound was characterized by comparing its 1(H)-NMR, MS and IR spectra with natural ( -- )-ligustiphenol. In order to study the structure-activity relationships of ligustiphenol, it five analogues were designed and synthesized. The pharmacological screening of these analogues has been performed.

Abstract
Two new cytotoxic annonaceous acetogenins, named uvarigrin(1) and uvarigrandin A(3), were obtained from the roots of Uvaria grandiflora Roxb(Annonaceae). Based on X-ray analysis and Mosher's methodology, the overall absolute configuration of 1 was established as 15S, 17R, 18R, 21R, 22R, 36S. The absolute configuration of 3 was also resolved by Mosher's methodology. The relative configuration of the previously reported uvarigranin (2) was revised. Compound 1 showed cytotoxicity against HCT-8, Bel7402 and A2780 human tumor cell lines at ED50 levels of 0.15, 0.21 and 0.41 microgram.ml-1, respectively.

Abstract
Further studies on the root bark of Uvaria tonkinensis Finet et Gagnep. (Annonacease) led to the isolation of a new Annonaceous acetogenin, tonkinelin (1). The structure of 1 was elucidated on the basis of spectral data and chemical evidence. This compound represents an unusual type of C37 Annonaceous acetogenin, having neither tetrahydrofuran (THF) nor epoxide rings and possessing only a vicinal diol in the hydrocarbon chain. Preliminary pharmacological tests showed that tonkinelin (1) inhibits human leukemia (HL-60) and human colon adenocarcinoma (HCT-8) cell lines in vitro.
