菱湖鱼病工作站: 现代科学改造中国传统养鱼业的序曲

寄生虫是水产养殖中最主要的病原类群之一,对鱼类苗种直至成鱼各个阶段的危害都十分严重。我国的鱼病学即是从鱼类寄生虫的研究发端并逐步发展起来的。本文从病原生物学、生态学、药物学、免疫学四个方面回顾了我国淡水鱼类寄生虫自新中国建立初期至今70年间 (1953年—2023年)的研究历程和已取得的成绩,并对未来的发展趋势和前沿热点进行了展望。本文为从事鱼类寄生虫学以及水产其他相关研究的读者提供了关于中国鱼类寄生虫研究的历史、现在发展水平和未来发展动向等较为全面的素材。

EDACO,a derivative of myricetin,inhibits the differentiation of Gaoyou duck embryonic osteoclasts in vitro

1. This study determined the effects of (E)-3-(2-(4-(3-(2,4-dimethoxyphenyl)acryloyl)phenoxy)ethoxy)-5,7-dimethoxy-2-(3,4,5-trimethoxyphenyl)-4H-chromen-4-one (EDACO) on the differentiation of Gaoyou duck embryonic osteoclasts cultured in vitro.

2. Bone marrow mononuclear cells (BM-MNC) were collected from 23-d-old Gaoyou duck embryos and induced by macrophage colony-stimulating factor and receptor activator of nuclear factor κB ligand in the presence of EDACO at different concentrations (i.e. 10, 20, 40, 80 and 160 µM). Tartrate-resistant acid phosphatase (TRAP) staining and resorption ability determination were conducted.

3. Results suggested that EDACO suppressed the shaping of positive multinucleated cells and the number of TRAP-positive cells in the 20, 40, 80 and 160 μM EDACO groups was significantly decreased (P < 0.05 or P < 0.01). Besides, the absorption activity of differentiated duck embryonic osteoclasts was significantly inhibited (P < 0.05) in both 80 and 160 μM EDACO groups.

4. Overall, EDACO can inhibit the differentiation of BM-MNC into mature osteoclasts in duck embryos.1     

桉油溶液剂的急性毒性和安全药理学研究

灌胃给药(ig)研究桉油溶液剂对大鼠的急性毒性。安全药理学试验以高剂量(30%)、中剂量(18%)、低剂量(6%)分别给予大鼠0.3 m L/只涂抹桉油溶液剂,观察其对大鼠神经系统、心血管系统和呼吸系统的影响。桉油溶液剂对大鼠的经口半数致死量(LD50)为3811.5 mg/kg。桉油溶液剂对大鼠的中枢神经系统、呼吸系统和心率等均无明显影响。桉油溶液剂是一种较安全的局部外用药,适合在临床上推广应用。桉油溶液剂经生产实践和兽医临床试验证明具有良好的治疗动物疥螨病效果。     

Antitumor Profile of Carbon-Bridged Steroids (CBS) and Triterpenoids

This review focuses on the rare group of carbon-bridged steroids (CBS) and triterpenoids found in various natural sources such as green, yellow-green, and red algae, marine sponges, soft corals, ascidians, starfish, and other marine invertebrates. In addition, this group of rare lipids is found in amoebas, fungi, fungal endophytes, and plants. For convenience, the presented CBS and triterpenoids are divided into four groups, which include: (a) CBS and triterpenoids containing a cyclopropane group; (b) CBS and triterpenoids with cyclopropane ring in the side chain; (c) CBS and triterpenoids containing a cyclobutane group; (d) CBS and triterpenoids containing cyclopentane, cyclohexane or cycloheptane moieties. For the comparative characterization of the antitumor profile, we have added several semi- and synthetic CBS and triterpenoids, with various additional rings, to identify possible promising sources for pharmacologists and the pharmaceutical industry. About 300 CBS and triterpenoids are presented in this review, which demonstrate a wide range of biological activities, but the most pronounced antitumor profile. The review summarizes biological activities both determined experimentally and estimated using the well-known PASS software. According to the data obtained, two-thirds of CBS and triterpenoids show moderate activity levels with a confidence level of 70 to 90%; however, one third of these lipids demonstrate strong antitumor activity with a confidence level exceeding 90%. Several CBS and triterpenoids, from different lipid groups, demonstrate selective action on different types of tumor cells such as renal cancer, sarcoma, pancreatic cancer, prostate cancer, lymphocytic leukemia, myeloid leukemia, liver cancer, and genitourinary cancer with varying degrees of confidence. In addition, the review presents graphical images of the antitumor profile of both individual CBS and triterpenoids groups and individual compounds.
