Complete removal of villous as well as upper-crypt epithelium was achieved in vivo by vibration of an intestinal segment using tetraphenylboron sodium (TPB) as a disassociation agent.
Hand-reared Bar-headed goslings (Anser indicus) were always left alone by the human parent in one room, while in another room the parent was always with them. After 13--22 h of experience in each room and at an age of 4--5 days individual goslings were left alone for 5 min in each room. They uttered significantly fewer distress calls in the room in which they were accustomed to being left alone by the parent. The result is interpreted in terms of environment-dependent calibration of interindividual distances. Such weighted distances are expected to be important variables in the short-term control of attachment behaviour.

Therapy with antituberculosis drugs is not indicated in patients with isolated cervical lymph node infection due to mycobacteria other than tuberculosis (MOTT); resectional surgery is the treatment of choice in these cases. The reason for this study was a striking increase in the incidence of this disease in children referred to the University Hospital in Aachen. In the period from 1987 to 1990, we saw only 1 case of nontuberculous mycobacterial cervical lymphadenitis among 77 cultured specimens; in contrast to this, out of 85 specimens examined between 1991 and March 1993 were positive, with an increasing tendency. The patients were treated surgically by adequate conservative neck dissection. The outcome was excellent in all cases.
