Variations among rice cultivars on root oxidation and Cd uptake.

In order to understand the mechanisms on the variation between rice cultivars in Cd uptake and accumulation, two pot soil experiments were conducted with typical rice cultivars that varied greatly in soil Cd uptake. The experiments with six rice cultivars showed that the root oxidation abilities of rice differed with rice cultivars and also with types of the cultivars, the cultivars with indica consanguinity were significantly higher than the cultivars with japonica consanguinity. Root oxidation abilities of the rice cultivars correlated positively and significantly (P < 0.

[Relationship between bleomycin-induced pulmonary fibrosis and vascular endothelial cell injury].

Objective: To explore the relationship between the injury of vascular endothelial cells and formation of lung fibrosis by bleomycin (BLM) in rats.

Methods: The rats of experimental groups were treated with bleomycin intratracheally to induce pulmonary fibrosis. The expression of vascular endothelial growth factor (VEGF) in pulmonary tissues were analyzed qualitatively and quantitatively by immunohistochemistry and image analysis system.

The study between the dynamics and the X-ray anatomy and regularizing effect of gallbladder on bile duct sphincter of the dog.

Aim: To study the relationship between the radiological anatomy and the dynamics on bile duct sphincter in bile draining and regularizing effect of gallbladder.

Methods: Sixteen healthy dogs weighing 18 kg to 25 kg were divided randomly into control group and experimental group (cholecystectomy group). Cineradiography, manometry with perfusion, to effect of endogenous cholecystokinin and change of ultrastructure were employed.

Effect of cholesterol liposomes on calcium mobilization in muscle cells from the rabbit sphincter of Oddi.

Aim: To analyze the influence of cholesterol liposome on the Ca2+ mobilization of cultured muscle cells in the rabbit sphincter of Oddi's.

Methods: New Zealand rabbit was sacrificed and the sphincter of Oddi (SO) segment was obtained aseptically. The SO segment was cut into pieces and cultured in DMEM solution.
