Bovine serum hormone concentrations after thyroprotein and thyrotropin releasing hormone.
Twenty-four Holstein heifers were assigned randomly to one of four t reatment groups to be given: 1) thyroprote in (TP) for 6 days; 2) casein for 6 days; 3) TP for 27 days; or 4) casein for 27 days. Thyrotropin releasing hormone (TRH, 33.3 /~g/100 kg BW) was given at 1030 and 1330 hr on day 6 or 33 to heifers treated for 6 or 27 days, respectively. Prior to TRH treatment , serum thyroxine (T4) ...
متن کاملGrowth hormone response to thyrotropin releasing hormone in a pellagrin.
An abnormal hyperresponse of GH to intravenous injection of TRH in a 66-year-old female pellagra patient with typical 3'D's was reported. Diagnosis of pellagra was mainly based on her clinical course and manifestations, although serum levels of nicotinic acid and serotonin were within the normal range. Serum vitamin A and B2 levels were low. However, these findings did not exclude the diagnosis...
متن کاملGrowth hormone responses to growth-hormone-releasing hormone and thyrotropin-releasing hormone in diabetic patients with and without retinopathy.
Growth hormone (GH) responses to growth-hormone-releasing hormone (GRH) and thyrotropin-releasing hormone (TRH) were studied in 17 diabetic patients. Ten patients (group 1) had retinopathy corresponding to stage III-V (Scott's classification), and the remaining seven patients (group 2) had no retinopathy despite longer duration of diabetes in comparison with the patients in group 1. There were ...
متن کاملGrowth hormone releasing hormone or growth hormone treatment in growth hormone insufficiency?
Sixteen prepubertal children who were insufficient for growth hormone were treated with growth hormone releasing hormone (GHRH) 1-40 and GHRH 1-29 for a mean time of nine months (range 6-12 months) with each peptide. Eleven children received GHRH 1-40 in four subcutaneous nocturnal pulses (dose 4-8 micrograms/kg/day) and eight (three of whom were also treated with GHRH 1-40) received GHRH 1-29 ...
متن کاملGrowth hormone response to growth hormone-releasing hormone in beef cows divergently selected for milk production.
In dairy cattle, increased circulating growth hormone has been associated with selection for greater milk yield. This study tested the hypothesis that beef cows divergently selected for milk production would have differing GH responses to a challenge dose of GHRH. Growth hormone response to a challenge of GHRH was measured in 36 Angus-sired cows ranging from 6 to 10 yr of age. The cows were cla...
