Abstract

Comparative histopathological effects were observed on the digestive glands (hepatopancreas) of freshwater snail species, Vivipara bengalensis and Lymnaea acuminata infected with single (furcocercous cercariae) and double infection of digenean trematode larvae (gymnocephalous cercariae + metacercariae), respectively. Digestive glands of both the snail species revealed degenerative changes in their digestive gland tubules. The latter became irregular in shape, reduced in size with enlarged lumen and inter-tubular space besides rupturing of digestive tubules. These changes were correlated with the size and types of trematode larvae, single or double infection and degree of parasitemia. Autolytic necrosis of numerous tubules was found in digestive glands infected with double and very severe single infection. None of the tubules was found to be invaded by sporocyst, redia and cercaria. However, metacercariae were seen to invade digestive tubules of Lymnaea species.

Gibt es eine Wende bei den bioresorbierbaren Gefäßstützen?

In den USA ist erstmals eine bioresorbierbare Gefäßstütze – auch Scaffold genannt – zur Rekanalisation infrapoplitealer Arterien bei schwerer PAVK zugelassen worden. Das markiert einen Wendepunkt in der Geschichte dieser speziellen Gefäßstützen.
