Hypophysectomized rats were injected intraperitoneally for 4 days with various doses of homocysteic acid or growth hormone. The effects of these compounds on epiphyseal cartilage thickness and circulating somatomedin activity levels were evaluated in an attempt to repeat the results of Clopath, Smith, and McCully, who reported that this compound had growth hormone-like activity. DNA polymerase activity in livers of animals treated with growth hormone or with 10 mg/day of homocysteic acid was also measured. Using larger number of animals and including higher doses of homocysteic acid than those previously employed, we did not observe an increase of epiphyseal cartilage thickness in homocysteic acid treated hypophysectomized rats. Growth hormone significantly increased cartilage thickness. DNA polymerase levels in homocysteic acid treated hypophysectomized rats were not substantially increased although a larger, dose-dependent increase was observed with pGH and hGH. Neither homocysteic acid nor GH increased circulating somatomedin activity under the conditions used in this investigation. These observations demonstrate that homocysteic acid was not a substance with growth hormone-like activity in our hands and cast doubt on its possible future usefullness as a substitute for GH in clinical situations.
