The distribution of flavonoids in chloroplasts of twenty five species of vascular plants

A survey was made of the major flavonoids in whole leaf extracts and in chloroplast preparations from twenty five species of vascular plants including Anthophyta (20), Coniferophyta (1), Ginkophyta (1), Pterophyta (2), and Arthrophyta (1). The chloroplasts variously contained derivatives of flavones, C-glycosylflavones, flavonols, flavanones, isoflavones, 3-deoxyanthocyanidins, and anthocyanins. Twenty three species contain one or more flavonoids in isolated chloroplast, usually in a pattern quite similar to that found in whole-leaf extracts but occasionally showing enrichment of one or more flavonoids in the chloroplasts. Flavonoids are apparently absent from chloroplasts of Phaseolus aureus and Morus alba although whole-leaf extracts of these species are rich in quercetin derivatives.     

Natural genital herpesvirus hominis infection in chimpanzees (Pan troglodytes and Pan paniscus)

Type 2 Herpesvirus hominis was isolated from pustulovesicular lesions on the external genitalia of two chimpanzees. Histopathologic examination of biopsy specimens from both animals revealed typical herpetic changes which included necrosis, superficial ulceration acute inflammatory cell infiltration, multinucleated syncytial giant cells, and intranuclear inclusions. Large numbers of herpes-type viruses were demonstrated by electron microscopy in biopsy specimens from both animals. Serologic studies also demonstrated infection of these animals with Herpesvirus hominis.
