Rectal cancer recurrence after prior resection and radiotherapy: palliation following additional surgery.

Unlabelled: Patients with rectal cancer may develop local recurrence despite cancer resection plus treatment with high dose radiation therapy. In this report, symptomatic patients received benefit from repeat resection. The morbidity and mortality can be maintained at an acceptable level with meticulous dissections and consistent use of reconstructive procedures.

Discriminative stimulus properties of lithium chloride in rats.

1. Adult male rats were trained to discriminate between an injection of lithium chloride (56 or 75 mg/kg) and saline in a two-lever operant chamber during a 20-minute session. 2.

Effects of chlordiazepoxide, 8-OH-DPAT and ondansetron on radiation-induced decreases in food intake in rats.

Studies of radiation effects on performance are often complicated by concurrent radiation-induced decreases in feeding behavior (i.e., "anorexia").
