[Clinical application of ultrasonographic indexes for assessment of amniotic fluid volume].

Objective: To find the favorable interval of assessment of amniotic fluid volume and the optimal standard for oligohydramnios.

Methods: To determine actual amniotic fluid volume (AAFV) by collecting amniotic fluid during cesarean section and compare it with maximum vertical pocket (MVP) and amniotic fluid index (AFI) in different interval between cesarean section and measurement and test the sensitivity and specificity of MVP and AFI of different standard.

Results: The ultrasonographic results were divided into three groups according to the interval between measurement and delivery: within 24 hours group, 24-96 hours group and longer than 96 over hours group.

[Study on nuclear matrix protein in leukemia cells].

Objective: To compare the composition of nuclear matrix proteins (NMP) between leukemia cells and normal bone marrow cells.

Methods: NMP was isolated by high-salt extration and identified by SDS-PAGE and western blotting.

Results: Increase in NMP was demonstrated in acute and chronic myelogenous leukemic cells as well as in the blast phase of chronic leukemia.

[Experimental study on bone formation in a denser coral used for repairing cortical defects in dogs].

The present study was designed to investigate a coral skeleton, Favites, which was originated from the reef builders in Hainan island, as a bone substitute. The coral Favites, like porites, is composed of anagonite (CaCO3), but contains less volume of porosity, higher strength and denser construction than Porites. After implanted into cortical bone defects in mandibles and femurs of dogs, skeleton fragment of coral Favites demonstrated good biocompatibility and biodegradability.
