A scanning electron microscope observation is carried out on glycine soja L., which grows around the estuary of the Yellow River, in Kenli County, Shandong Province. It is first discovered that there are salt glands, in the shape of balls, on the surface of the stems and leaves of G. soja L., and distributed at the intercellular layer. With a handle at the base, the salt glands are not equal in size, and show a layer-upon-layer structure. They have a diameter of 21 .6 μm, a handle length of 1.2 μm, their secretory pore’s diameter is 5.6 μm. There are two ways to secrete salt ions: younger glands secrete salt ions through the secretory pore, and mature glands by breaking themselves.

Two one dimensional heterometallic coordination polymers {[CuEr(Gly) 5(H 2O) 2](ClO 4) 5·H 2O} n (1) and {[Cu 2Gd 2(Gly) 10 (H 2O) 4](ClO 4) 10 ·4H 2O} n (2) (Gly = glycine) were synthesized and structurally and characterized magnetically. Complex 1 crystallizes in a triclinic space group of P 1 with a =1.1769(2) nm, b =1 2289(3) nm, c = 1.4452(3) nm, α = 89.90(3)°, β = 71.88(3)°, γ = 62.15(3)°, and Z =2. The carboxyl groups of glycine molecules take two coordination modes. The first one acts as a bidentate bridging ligand only. The second is a tridentate bridge that coordinates to three different metal ions. Each erbium ion is eight coordinated, taking a distorted square antiprism arrangement. The copper ion has a square pyramidal coordination polyhedron. The topological structure of complex 2 is similar to complex 1, but there are some disparities in the bond lengths and bond angles. It is also triclinic space group of P 1 with a = 1.2479(3) nm, b = 1.4489(3) nm, c =2.0885(4) nm, α = 109.56(3)°, β = 93.75(3)°, γ = 93.54(3)°, and Z =2. Variable temperature susceptibility measurements show that there is a weak ferromagnetic interaction between the Gd 3+ and Cu 2+ ions in complex 2.

The title complex [Nd(Gly)(H 2O) 7]Cl 3 was synthesized and its crystal structure was determined by X ray diffraction to obtain a final R value of 0 026 0 and a wR value of 0 086 8. The crystal is of monoclinic system with a space groug Pm . Every two neodymium ions in the crystal are connected with a carboxyl group to form a polymeric chain molecule. And each neodymium ion is further coordinated with seven oxygen atoms from water molecules. The counter ion(Cl -) is non coordinated to fill up the space between the polymeric chains. So the Nd 3+ cation is nine coordinated and the coordination polyhedron is a trigonotetradecahedron. In addition, there exists the mirror symmetry in the complex.

Subclinical necrotic enteritis(NE) is an economically important disease in the broiler industry. With the move towards removal of antibiotics from feeds, solutions to control subclinical NE are desperately being sought. Dietary glycine has been shown to promote proliferation of Clostridium perfringens(Cp) and may thus be useful to include in a NE challenge model. A study was conducted to evaluate the effect of increased dietary glycine levels on subclinical NE. A 2 × 2 × 2 factorial arrangement of treatments was carried out using day-old male Ross 308 chicks(n = 624) allocated to 48 floor pens with 8 treatments of 6 replicates with 11 birds per treatment. Factors were: Cp challenge(C-or C+), Eimeria spp. challenge(Eor E+), and dietary glycine in the grower diet(0 or 10 g/kg). Birds had higher FCR when challenged with Eimeria(P glycine on d 24(P glycine reduced feed intake on d 24 and increased weight gain on d 35(P glycine interaction(P glycine compared with those with Eimeria and glycine or the unchallenged birds. Lesion score interactions between Cp and glycine(P glycine compared to those not challenged with Cp. This study suggests that using glycine can partially replace Eimeria in a subclinical NE challenge model in promoting the intestinal lesions but not impairing chicken performance.

Ⅰ. INTRODUCTION A free radical with both electron-donating and electron-withdrawing groups attached to the central carbon atom is said to show special chemical stability. This phenomenon is known as captodative effect. And the rate, selectivity, yield and mechanism are often influenced in a reaction involving such a radical. Therefore, captodative effect has become an interesting subject to many chemists recently.

Salt is an abiotic stress factor that strongly affects soybean growth and production. A single dominant gene has been shown to confer salt tolerance in the soybean cultivar Tiefeng *** objective of the present study was to genetically map the salt-tolerance gene in an F2:3population and a recombinant inbred line(RIL) population derived from a cross between two cultivated soybeans, Tiefeng 8(tolerant) and 85-140(sensitive). The F2:3families and RILs were treated with 200 mmol L-1Na Cl to evaluate salt tolerance. The F2:3population showed 1(42 tolerant): 2(132 segregating): 1(65 sensitive) segregation, indicating a single dominant gene for salt tolerance in Tiefeng 8. A sequence-characterized amplified region(SCAR) marker from a previously identified random amplified polymorphic DNA(RAPD)marker and four insertion/deletion polymorphism(In Del) markers were developed within the mapping region. Using these markers along with SSR markers, the salt-tolerance gene was mapped within 209 kb flanked by SCAR marker QS08064 and SSR marker Barcsoyssr_3_1301 on chromosome 3. Three markers that cosegregated with the salt tolerance gene and SCAR marker QS08064 were used to genotype 35 tolerant and 23 sensitive soybean accessions. These markers showed selection efficiencies of 76.2% to94.2%. The results indicate that these markers will be useful for marker-assisted breeding and facilitating map-based cloning of the salt tolerance gene in soybean.

BACKGROUND: Morphological and functional changes commonly occur in livers of brain-death donors. Preven- tion of liver injury from brain-death will benefit the results of transplantation. This study was conducted to evaluate the protection effects of glycine on the liver of brain-death donor. METHODS: Fourty-two male Wistar rats were randomly divided into brain-death donor (BDD) group (B), glycine pretreatment group with BDD (G), and strychnine pre- treatment group with BDD(S). For these groups, brain death model was established in donor rats and liver trans- plantation was performed subsequently utilizing microsur- gical techniques. After the establishment of the model and during cold rinsing of liver donors or liver reperfusion of recipients, glycine was given at a dose of 0. 6 mmol, 25 μmol and 25 μmol in the group G, and a same dose of gly- cine and strychnine (1000 :1) was prescribed for the group S, but nothing for the group B. Before cold rinsing at 2 and 6 hours after portal vein(PV) reperfusion, blood sam- ples were taken from infrahepatic vena cava (IHVC) to de- termine the levels of alanine aminotransferase (ALT), as- partate aminotransferase (AST), tumor necrosis factor al- pha (TNF-α) and hyaluronic acid (HA). At 6 hours after PV reperfusion, graft samples were fixed for morphological observation and apoptosis of hepatocytes was detected using the TUNEL method. RESULTS: Before liver cold rinsing and at 2 and 6 hours af- ter PV reperfusion, the serum levels of ALT, AST, TNF-α, HA and apoptosis index (AI) in the groups B and S were significantly higher than those in the group G (P 0.05). Electron microscopy showed that Kupffer cells were activated and hepatic cells injured more obvious- ly in the groups B and S than in the group G. CONCLUSION: glycine pretreatment can improve the via-bility of the liver of the brain-death donor rat.
