Aqueous extract of cotton has allelopathic effect on Raphanus sativus, Brassica campestris, Lactuca indica, Brassica campestris, Echinochloa crusgall, Setaria viridis and Abutilon theophrasti and its inhibition effect gradually strengthens with increasing concentration. Aqueous extracts from stems, leaves and roots of cotton inhibit or accelerate seed germination and seedling growth, and activity of enzyme of seedling root of cotton. While aqueous extracts from stems and leaves of cotton are 0.02 gmL^(-1), root length, shoot length, lateral root number and dry weight of cotton respectively increase by 10.3%, 3.1%, 22.9% and 2.4% over the control. The above mentioned indexes are lower than the control by 34.4%, 39.2%, 40.6% and 19.0% respectively as the aqueous extracts are 0.1 gmL^(-1). At the same time, root activity and SOD activity decrease by 38.2% and 36.7%, while POD activity and MDA content increase by 52.3% and 36.5%. Growth indexes of plant receptors increase at low concentrations but decrease at high concentrations of aqueous extracts. The allelopathic effect of aqueous extract of stems and leaves is stronger than that of root.

The Ca2+ salt solution as a new regenerant was presented in this paper. The influences of the calcium salt proportioning, temperature, dosage and flow rate on anion exchange fiber regeneration were studied. High regeneration can be obtained with 0.5 mol/L CaCl2+8 g/L CaO+6.5 °Bx sucrose solution at 70～80 ℃, the dosage of the Ca2+ salt solution was about half of the raw decoloring syrup, the regenerant flow rate should be lower than that of the raw decoloring syrup. It was shown that stable decolorization rate and lower decline in exchange capacity could be achieved with the new regenerant. It performed more effectively than the traditional sodium salt regenerant with less discharge of waste water.

我们知道乳头液可以是生理性或病理性的，非妊娠哺乳期的乳头溢液发生率约为3%8%，溢液可以是无色、乳白色、淡黄色、棕色、血性等，也可呈水样、血样、浆液样脓性；溢液量可多可少，间隔时间亦不一样，一般晚期患者溢液比较严重，这时可以对乳头溢液应进行涂片细胞学检查以明确。
