The Histopathological Study on “Green Decay Diseases” of Undaria Pinnatifida in Dalian;

Histology and cytology observation on the rot disease of Laminaria japonica caused by alginic acid decomposing bacteria;

The infection tests showed that the alginic acid decomposing bacteria isolated were the main pathogenic bacteria which caused the rot disease of Laminaria japonica.

In order to study the physiological and biochemical Changes of Laminaria japonica in the process of rot disease, Laminaria japonica was induced to rot disease under the experimentally ecological conditions, and the changes of 4 indices (including soluble sugar, soluble protein, total antioxidative ability and superoxide dismutase (SOD)) were measured during the experiment.

UV-Visible Spectrophotometry Study on the Interaction of Brilliant Green with Deoxyribonucleic Acid and Application to DNA Assay;

The method is based on the catalytic effect of trace activated manganese(Ⅱ) on the oxidation of brilliant green and 1-(2-pyridylazo)-2-naphthol by patassium periodate in Na2HPO4-KH2PO4 medium.

The best conditions for determination of trace platinum(Ⅳ) in platinum(Ⅳ)-tin(Ⅱ)(chloride)-brilliant green system by spectrophotometry was studied.

Determination of Trace Fe(Ⅲ) by Catalytic Kinetic Spectrophotometry of Fe(Ⅲ)-Brillant Green-H_2O_2 System;

Using NTA as an activating agent,Mn(Ⅱ) can catalyze reaction of brillant green with potassium periodate in HAc NaAc buffers.

Pathogeny Study on Tail-rot Disease in Marine Cage-cultured Pesudociaena crocea;

The tail-rot disease of Pseudosciaena crocea is one of the major diseases in marine cage-cultured Pseudosciaena crocea in Zhoushan.
