Radical scavenging and angiotensin converting enzyme inhibitory activities of standardized extracts of Ficus racemosa stem bark

The present study evaluated the radical scavenging and angiotensin converting enzyme (ACE) inhibitory activity of cold and hot aqueous extracts of Ficus racemosa (Moraceae) stem bark. The extracts were standardized using HPLC. Radical scavenging activity was determined using 1,1‐diphenyl‐2‐picrylhydrazyl radical and angiotensin converting enzyme inhibitory activity using rabbit lung and partially purified porcine kidney ACE. HPLC profiles of cold aqueous extract (FRC) showed the presence of bergenin, an isocoumarin, while hot aqueous extract (FRH) was found to contain ferulic acid, kaempferol and coumarin in addition to bergenin. FRH showed significantly higher (p ≤ 0.01) radical scavenging activity than FRC and butylated hydroxytoluene (BHT), consequently resulting in a significantly lower (p ≤ 0.01) IC₅₀ value than FRC and BHT. Both the extracts exhibited a dose dependent inhibition of porcine kidney and rabbit lung ACE. FRH showed significantly higher (p ≤ 0.01) activity than FRC with lower IC₅₀ values of 1.36 and 1.91 μg/mL respectively, for porcine kidney and rabbit lung ACE, compared with those of FRC (128 and 291 μg/mL). Further, a significant correlation (r = 0.893; p ≤ 0.05) was observed between radical scavenging activity and ACE‐inhibitory activity. This is the first report on the ACE‐inhibitory activity of F. racemosa stem bark suggesting its potential to be utilized as a therapeutic alternative for hypertension.

Lymphocytic thrombophilic arteritis complicated by systemic involvement

Lymphocytic thrombophilic arteritis (LTA) is a recently described entity defined by primary lymphocytic vasculitis; it typically has a chronic indolent course. We describe a patient who presented with clinical and histological findings consistent with LTA and later developed bilateral focal testicular infarcts as well as an acute median nerve neuropathy.     

Allergic contact dermatitis from Dittrichia viscosa (L.) Greuter

9 cases of contact sensitivity to Dittrichia viscosa, mainly with an airborne pattern, are described. All patients reacted to the fresh leaf of the plant and to its ethereal extracts at 1 and 0.5% pet., and some of them also to that at 0.1% pet. Positive reactions to Frullania dilatata, Laurus nobilis, some other members of the Compositae, and helenin were observed, suggesting the diagnosis of a sesquiterpene-lactone-induced allergic contact dermatitis.

Cholesterinemboliesyndrom nach Koronarangiographie*

Zusammenfassung Das Cholesterinemboliesyndrom (CES) ist eine den Dermatologen kaum bekannte Multiorganerkrankung, die eine häufige und schwerwiegende Komplikation nach angiographischen und gefäßchirurgischen Interventionen, aber auch nach Lysetherapien darstellt. Die Diagnose einer Cholesterinembolie wird nur in knapp einem Drittel der Fälle zu Lebzeiten der Patienten korrekt gestellt und die Häufigkeit dieses Krankheitsbildes in der Regel unterschätzt. Pathognomonisch für die Erkrankung ist die Konstellation akraler Schmerzen, schlecht heilender Ulzerationen und Nekrosen, einer Livedo racemosa bei intakten peripheren Pulsen und dem Neuauftreten oder einer Verschlechterung einer bestehenden Niereninsuffizienz und arteriellen Hypertonie. Beweisend für die Diagnosestellung ist letztlich der Nachweis von Cholesterinkristallen durch Biopsien der betroffenen Organe. Es wird über einen 66-jährigen Patienten berichtet, der im Anschluss an eine Koronarangiographie mit PTCA und Stentung der A. coronaria dextra (RCA) akrale Nekrosen, Livedo racemosa und eine dialysepflichtige Niereninsuffizienz entwickelte.*Herrn Prof. Dr. med. Hans-Dieter Göring zum 65. Geburtstag in Dankbarkeit gewidmet.     

Reversible Antifertility Activity of Hydroalcoholic Extract of Ficus Racemosa L.In Male Mice

Objective To evaluate male antifertility activity of hydroalcoholic extract of Ficus racemosa bark. Methods Swiss male mice were orally administered hydroalcoholic extract of Ficus racemosa bark (50 mg/kg for 30 d and 100 mg/kg body weight for next 30 d), and the effect of the treatment on body weight, reproductive organs weight, sperm, biochemical profile (sialic acid in epididymis and fructose in seminal vesicle), fertility and vaginal contraceptive efficacy was investigated. Recovery studies were also performed. Results Extract reduced fertility to 70% within 60 d. Suppression of cauda epididymis sperm count, motility, viability and abnormal morphology was observed. Marked reduction was noted in the weight of reproductive organs and the level of sialic acid in epididymis and fructose in seminal vesicle. Vaginal application of bark extract exhibited 80% vaginal contraceptive efficacy. After cessation of plant extract treatment, the altered parameters recovered after 60 d. Conclusion Clinical assessment of male antifertility agents should include acceptability, safety and efficacy during and after the treatment. The above results revealed the potential, reversible male antifertility effect of hydroalcoholic extract F. racemosa bark.
