Abstract

Thyroxine induces tail resorption in anurans both in vivo and in vitro. This event is accompanied by an increase in the activity of the hydrolytic enzymes acid phosphatase and B‐N‐acetylglucosaminidase. Prolactin treatment promotes tail growth and directly antagonizes the action of thyroxine on tail tissues. This is evident at the gross morphological level as well as at the biochemical level where prolactin inhibits the increase in activity on the hydrolytic enzymes that occurs during thyroid hormone induced resorption.

Last-instar larvae of the beet armyworm, Spodoptera exigua, fed on diet containing the nonsteroidal molting hormone agonist, tebufenozide, at 1 mg/liter, exhibited a premature induction of chitin synthesis. Treatment with tebufenozide apparently caused normal amounts of chitin to be formed in the cu

## Abstract In vitro studies have shown that CD44 is involved in the fusion process of osteoclast precursor cells. Yet, in vivo studies do not support this, since an osteopetrotic phenotype has not been described for CD44 knock‐out (CD44 k.o.) mice. This discrepancy may suggest that the role of CD4
