Data from the same 138 New York dairy farms for the years 1994 through 1997 were used to estimate whether Bovine Somatotropin (bST) generated profits for adopters. Data from these same farms from 1993 were used to sort farms into groups by production per cow, profit per cow, and farm size, in order to test bST response by these delineators. Statistically, farms that used bST on average experien...

“Aging is not a beautiful thing.“ This sentence is heard by many patients of acromegaly at their visit to the doctor. The changes in the body are often not recognized or misclassified by medical professionals for a very long time. Often, a diagnosis is only reached after 9 or even 10 years. A visit to the endocrinologist can shed light on the condition, however. There is an excess production of...

Evaluation of the GH secretion using pharmacological GH stimulation tests remains controversial in the diagnosis. The authors present diagnostic problems in recognizing growth hormone deficiency on the basis of literature.

The immunocytological detection of adrenocorticotrophic hormone (ACTH) and somatotropin release inhibitor factor (SRIF) like immunoreactivity was carried out on tumour cells from bronchial brush smears in 39 cases of lung tumours. Results obtained were compared with the cytological and histological diagnosis and confirmed the high incidence of ACTH synthesis by malignant bronchial carcinoma cel...

Earlier immunological investigations of growth hormone (somatotropin) isolated from bovine and human pituitaries showed that these two protein hormone preparations form speciesspecific antibodies, as evidenced by the results of precipitin ring tests with rabbit antiserum and of anaphylactic shock experiments in guinea pigs (1, 2). It was further demonstrated that the rabbit antiserum exerts in ...

I describe a convenient method for stripping hormones and other ligands from human serum. Formation of a serum/charcoal colloid is avoided by incubating serum on a limited surface area with activated charcoal, in a lateral oscillating shaker. Particle-free serum of negligible turbidity is obtained without ultracentrifugation by ejecting the centrifugate through a cellulose ester membrane. By th...

An octacosapeptide that we named pro-somatostatin has been isolated from acid extracts of porcine hypothalami and found to have the amino acid sequence Ser-Ala-Asn-Ser-Asn-Pro-Ala-Met-Ala-Pro-Arg-Glu-Arg-Lys-Ala-Gly-Cys-Lys-Asn-Phe-Phe-Trp-Lys-Thr-Phe-Thr-Ser-Cys. This octacosapeptide possesses high somatotropin (growth hormone) and prolactin release-inhibiting activity in vitro. It also crossr...
