It has been a scientific consensus that Ulva prolifera green tide that break out annually between May and August in the recent decade off eastern coast of Yellow *** investigate the ecological mechanism of the decline of *** green tide,we compared the physiological characteristics of *** samples collected in three stages of the green tide in Subei Shoal north Jiangsu,the initiation point,on May 10(early,the initiation),July 10(middle,the outbreak),and in Taipingjiao,Qingdao on August 10(late,the decline).Compared to the early samples,the middle,and late samples showed a lower chlorophyll content and photosynthetic e fficiency at a higher lipid peroxidation *** middle and later samples had fewer chloroplasts in the cells of *** than those in the early *** addition,the cells of *** sampled in the late stage showed ruptured and deformed cell *** in physiological function were reflected in the growth *** the middle and late *** samples presented negative growth *** analysis results show that the rising temperature was mainly responsible for the local decline of *** green *** high light-intensity that could induce the photoinhibition was also an important factor for the ***,*** population that remained in the Subei Shoal and those that northward drifted to Qingdao experienced the same decline processes:rising temperature and continuous high light conditions in the late phase of green tide reduced the photosynthetic capacity and destroyed the antioxidant system of the thallus,which lead to decrease of *** only difference is that the temperature in the Subei Shoal rose earlier than that in Qingdao;thus,*** remaining in the Subei Shoal went disappeared first.

Photosynthetic response of floating Ulva prolifera to diurnal changes of in-situ environments on the sea surface

Journal of Oceanology and Limnology 2019年第2期37卷 589-599页

During yellow sea green tide outbreak, the thalli of Ulva prolifera drifted more than 350 km on the sea surface from off shore of Jiangsu Province to Qingdao city, where they were exposed to complex changes of local environments. The purpose of this study is to investigate the response of the thalli to diurnal changes of environments on the sea surface, and a sea surface environment simulator (SSES) was designed to simulate the natural environment of floating U . prolifera mat. A control experiment is designed in the laboratory, which was processed under suitable conditions (20°C for temperature, 72 μmol photons/(m 2 ·s) for light intensity and 30 for salinity), and an in-situ research was conducted to study the photosynthetic responses of floating U . prolifera to diurnal changes of environments. The results show that the photosynthetic efficiency of the thalli decreased gradually with time, and decreased rapidly after 14:00 local time (LT). After exposed to the environment on the sea surface for 6 h, the photosynthetic activity of the thalli decreased significantly. Furthermore, physiological-level and molecular-level experiments revealed that non-photochemical quenching (NPQ), cyclic electron flow (CEF) and energy redistribution between PSI and PSII all played an important role in the strong photosynthetic plasticity of U . prolifera . NPQ is the most important photoprotective responses to environmental changes before 12:00 LT. The results also confirmed that the CEF and energy redistribution between PSI and PSII are the main synergistic eff ects for the thalli to adapt to the environmental changes when the process NPQ cannot work. And the result can further reveal the reason why U . prolifera can adapt to the living condition of long distance drift on the sea surface. The findings of this research could provide a theoretical basis for explaining outbreaks of the green tide and instructing the management of the problem.

过敏性鼻炎(AR)为鼻炎中最为常见的类型,临床主要表现为鼻痒、喷嚏、流清涕等,易反复发作。抗组胺药物、糖皮质激素等可有效控制其症状,但远期疗效不佳,不良反应较多[1]。中医学将AR归属于“鼻鼽”范畴,认为该病多因肺脾虚弱,风寒入侵,... 详细信息

过敏性鼻炎(AR)为鼻炎中最为常见的类型,临床主要表现为鼻痒、喷嚏、流清涕等,易反复发作。抗组胺药物、糖皮质激素等可有效控制其症状,但远期疗效不佳,不良反应较多[1]。中医学将AR归属于“鼻鼽”范畴,认为该病多因肺脾虚弱,风寒入侵,卫外不固而引起。益气脱敏汤主要功效为宣肺益气,止咳平喘,主治过敏症状。本研究在第二代抗组胺药物依巴斯汀治疗的基础上,联合应用益气脱敏汤治疗肺虚感寒型AR患者,取得较好疗效,现报道如下。
