“…Plasma leakage induced by NAP-l/iL-8 has been found to be dependent on tbe concomitant emigration of neutropbils (3)(4)(5). Calculation was therefore made of the volume of plasma leaking into skin sites per 10*" neutrophils entering each site so as to determine tbe constancy of plasma leakage per unit of neutrophils at differing time points (Fig.…”

SummaryNeutrophil accumulation and plasma leakage were measured in rabbit skin at sites stimulated with recombinant human neutrophil activating peptide‐1/interteukin‐8 (NAP‐1/IL‐8). Neutrophil accumulation occurred at doses equal to or greater than 10‐11 moles NAP‐1/IL‐8 per site. Co‐injection of prostaglandin E2 (PGE2) extended the threshold of inflammatory activity of NAP‐1/IL‐8 to less than 10‐13 moles/site and caused approximately three‐fold increases in neutrophil accumulation and ten‐fold increases in plasma leakage at the higher doses of NAP‐1/IL‐8 examined. Plasma leakage declined more rapidly than did neutrophil accumulation as lesions aged. It was postulated that an endothelial response may be initiated to limit plasma leakage during ongoing neutrophil emigration at sites stimulated with NAP‐1/IL‐8. The induction of vasodilatation by injection of PGE2 masked the decline of plasma leakage with time in lesions up to 120 min old. Co‐injection of the RNA synthesis inhibitor, actinomycin D, failed to abrogate the decline of plasma leakage with time, suggesting that de novo protein synthetic events such as production of the vasoconstrictor peptide, endothelin, are unlikely to contribute to the mechanism that restricts plasma leakage in older lesions. Although plasma leakage induced by NAP‐1/IL‐8 is dependent on the emigration of neutrophils, the results indicate that a mechanism, independent of de novo protein synthesis, restricts the rate of plasma leakage per neutrophil as lesions age.

“…The presence of phenolic compounds were analyzed using ferric chloride (Johansen, 1940); the starch was visualized using iodide zinc chloride (Strasburger, 1913); the lipidic substances using Sudan IV (Jensen, 1962) and the polysaccharides using ruthenium red (Johansen, 1940). The epidermis analysis in frontal view was conducted using leaf fragments dissociated with hydroalcoholic saphranine (Foster, 1949). The study of the venation pattern was conducted using fresh material which was cleared in 5% NaOH and in 50% sodium hypochlorite, then stained with hydroalcoholic saphranine and mounted in synthetic resin (Foster, 1949).…”

RESUMO:Sambucus australis Cham. & Schltdl. (sabugueiro-do-rio-grande, Caprifoliaceae) é uma planta medicinal descrita apenas na primeira edição da Farmacopéia Brasileira. A espécie é nativa no Brasil, e suas fl ores são utilizadas na medicina popular, na forma de infusão ou decocção, como diuréticas, antipiréticas, antiinfl amatórias, laxativo leve e no tratamento de doenças do aparelho respiratório. Visando elaborar uma monografi a farmacopéica atualizada e comparativa com a de Sambucus nigra L., de origem européia, foram estabelecidos os caracteres botânicos macro e microscópicos, através da metodologia clássica utilizada em morfoanatomia vegetal. São características macroscópicas: fl ores morfologicamente monoclinas; corola de sete a dez milímetros de diâmetro; pétalas com cinco, raro quatro nervuras paralelas; estames curtos e longos; gineceu em regra com cinco lóculos. São características microscópicas: cutícula espessa e estriada; ausência de idioblastos de areia cristalina de oxalato de cálcio; estômatos anomocíticos; brácteas anfi estomáticas; sépalas hipoestomáticas; pétalas anfi -hipoestomáticas; células epidérmicas da face abaxial de sépalas e pétalas retilíneas a sinuosas; células epidérmicas do fi lete alongadas e de paredes retilíneas; tricomas tectores e glandulares de diferentes tipos; brácteas, sépalas e pétalas com mesofi lo homogêneo; sistema vascular representado por feixes colaterais ou agrupamentos de elementos xilemáticos; presença de gotas lipídicas em todas as peças.Unitermos: Sambucus australis, Caprifoliaceae, farmacobotânica, morfoanatomia. (sabugueiro-do-rio-grande, Caprifoliaceae) is a medicinal plant described only in the fi rst edition of Brazilian Pharmacopoeia. This species is native to Brazil, and its fl owers are used in the folk medicine, with diuretic purpose, antipiretic, anti-infl ammatory, mild laxative and to treat respiratory diseases, on infusions or decoctions forms. Aiming at elaborating an updated pharmacopoeical monograph and comparing it with the monograph of Sambucus nigra L., from Europe, it was established the macro and microscopic botanical characters, through the classic methodology used in plant morpho-anatomy. The macroscopic characters are: morphologic monoclin fl owers; corolla with seven to ten millimeters of diameter; petals with fi ve, rarely four parallel veins; shorter and longer stamens; ovary oftenly with fi ve locules. The main microscopic characters are: thickned and striated cuticule; absense of idioblasts with calcium oxalate sandy cristals; anomocytic stomatas; amphystomatic bracts; hypostomatic sepals; amphi-hypostomatic petals; wavy and straight epidermal cells in the lower surface of sepals and petals; fi laments epidermal cells with narrow and straight walls; glandular and non-glandular trichomes of different types; homogeneous mesophyll in bracts, sepals and petals; vascular system represented by both collateral bundles and xylematic elements; volatile and non volatile oil globules in all structures.
