    Description / Table of Contents: Zusammenfassung Die Wurzeln von F. Chappar enthalten ein Anthocyanin, das dem Päonin ähnlich, aber nicht mit ihm identisch ist. Das entsprechende Anthocyanidin zeigt folgende Charakteristika:R f 0,57 (n-Butanol-Essigsäure—Wasser, 4:: 1 : 5,v/v) und sein Elektronenspektrum zeigt zwei breite maxima in den Bereichen 428–464 mμ bzw. 604–620 mμ. Papierchromatographisch werden zwei Zuckerkomponenten, Galaktose und Rhamnose, aufgefunden. Das Pterocarpinoid, Schmp. 180°, über das schonChaudhury et al.4 berichteten, wird als Bestandteil der Wurzel bestätigt. β-Sitosterin und 7-Hydroxyflavon, dieChaudhury et al.1 aus einem von der ganzen Pflanze erhaltenen Extrakt isolierten, fanden sich in der Wurzel.
    Notes: Abstract The roots of F. Chappar contain an anthocyanin which is similar to but not identical with peonin. Its corresponding anthocyanidin has the following characteristics:R f, 0.57 (n-butanol-acetic acid-water, 4:11: 5,v/v) and its electronic spectrum shows two broad maxima in the range 428–464 mμ and 604–620 mμ respectively. Paper chromatographic analysis indicated the presence of two sugar components, viz., galactose and rhamnose. We confirm the presence of the pterocarpinoid, m. 180° as the root constituent reported earlier byChaudhury et al.4. Besides, we have also isolated β-sitosterol and 7-hydroxyflavanone—whichChaudhury 1 et al. have isolated from the extractive obtained from the whole plant.

    Notes: Summary The effect of gamma irradiation at doses of 40- and 50 kR on the development of third stage larvae ofOesophagostomum columbianum and the protection conferred by these irradiated larvae against the nematode, was studied in 6–8 week old male Kashmir Merino lambs. At 40- and 50 kR doses, the third stage larvae failed to develop to the adult stage in the intestine. Though single vaccination with 2000, 50 kR irradiated larvae failed to protect the animals against the infection, vaccination with the same number of 40 kR irradiated larvae conferred a partial protection. The presence of adult worms ofO. columbianum in sites outside the intestine of 6–8 week old lambs have been demonstrated for the first time.

    Notes: Abstract The whole blood clotting time progressively increased from the second to the eighth week in lambs receiving a primary infection of Dictyocaulus filaria larvae. However, in vaccinated lambs it remained unaffected. Levamisole hydrochloride was ineffective when given 4 days after infection but restored the blood clotting time to near normal soon after treatment when it was given 30 days after infection.
