We have studied the effect of treatment with anthocyanosides from Vaccinium myrtillis on cholesterol-induced atheroma of rabbits. We have found that the drug did not modify the serum cholesterol levels, but decreased the proliferation of the intima the extracellular matrix production the calcium and lipid deposition in the aorta, and the DNA and lipid contents. The alterations in the biochemical composition of the isolated brain microvessels were also diminished. The following mechanism may explain the protective action of the treatment: the collagen of the vessel walls participates in the control of vascular permeability. This permeability is increased by a cholesterol-rich diet. The protective drug interacts with collagen, increasing its cross-links, thus diminishing the permeability in small, as well as in large blood vessels.

Article Synopsis
- Paperbark maple (Acer griseum) is an endangered plant in China, known for its striking red autumn leaves, but research on its leaf color change is limited.
- This study investigates the physiological and molecular processes behind the leaf color transformation by analyzing changes in chlorophyll, carotenoids, and levels of anthocyanidins across three stages: green, half-red, and red.
- Findings indicate that the compound cyanidin-3,5-O-diglucoside is likely responsible for the leaf reddening, and the research also identifies key transcription factors that regulate anthocyanin biosynthesis, which could inform breeding strategies for the species.

In this study, the QuEChERS and UHPLC-MS/MS method using a biphenyl stationary phase was developed and applied for the rapid separation of 12 anthocyanosides in grapes. Efficient separation was achieved for a wide range of mono- and un-glycosylated anthocyanosides. The linear ranges of the target anthocyanosides were 0.

May 1981
Thirty-one patients with various types of retinopathy were investigated with regard to the effect of anthocyanosides on the retinal vessels. Especially in patients with diabetic retinopathy, a positive influence on the permeability and tendency to hemorrhage was observed. The importance of internal treatment of the primary disease is pointed out.
