Abstract: A specific radioimmunoassay has been established for a growth hormone-dependent insulinlike growth factor (IGF) binding protein (BP) from human plasma. Although the assay was directed against a 53-kD, acid-stable BP subunit, the main immunoreactive BP in the circulation had an apparent molecular mass of approximately 125 kD. Only higher primate species showed cross-reactivity, and IGF-I, IGF-II, and other peptides were without effect. Circulating BP levels in healthy subjects rose threefold from early childhood to puberty. In 65 adults aged 18 to 65, the mean level (+/- SD) was 6.12 +/- 1.43 micrograms/ml, and declined with age. Strong growth hormone-dependence of BP was also seen; there was a 2.2-fold increase in active acromegaly and a 50-80% reduction in growth hormone deficiency. Poorly controlled diabetic subjects had BP levels 40% below normal, whereas in renal failure and third-term pregnancy a mild elevation was seen. Measurement of BP may provide a useful adjunct to IGF assays in growth disorders.

Abstract: The plasma concentrations of epinephrine were determined in healthy subjects administered epinephrine by subcutaneous injection of 0.5 mg or inhalation of 1.5 to 4.5 mg (10 to 30 inhalations from a metered-dose aerosol). The absorption of injected epinephrine was variable and in several cases very slow. The individual maximum values for epinephrine in plasma were 4.65 +/- 1.09 (range 0.74 to 8.31) nmol/L, and these maxima were attained 5 to 120 minutes after injection. Inhaled epinephrine was rapidly and dose dependently absorbed. Ten inhalations resulted in 2.72 +/- 0.84 (0.75 to 5.67) nmol/L within 5 minutes and 20 inhalations resulted in 7.19 +/- 1.78 (2.10 to 13.83) nmol/L with rapid increases and maxima within 20 minutes in seven of eight subjects. Gastrointestinal side effects were dose limiting when epinephrine was administered by inhalation. Our results indicate that inhalation of 2 to 3 mg of epinephrine produces rapid increases of epinephrine concentrations in plasma to levels that have previously been demonstrated to counteract bronchoconstriction induced by inhaled allergen in subjects with asthma. Inhalation has several advantages over injection for self-administration of epinephrine, e.g., in patients who are allergic to insect (Hymenoptera) stings. Apart from the absorption being more rapid, the locally high concentrations of epinephrine in the airways should be advantageous, since bronchoconstriction is one of the life-threatening phenomena of the anaphylactic reaction. This route of administration is also simple for the patient.

Abstract: It is well known that LH and human CG (hCG) induce an increase in total ovarian blood flow. The effect of LH/hCG on luteal blood flow, however, is unknown. This work studies the effect of hCG on both luteal and ovarian blood flows at different stages of pseudopregnancy in adult female rats. Pseudopregnancy was induced by mating with sterile male rats. The length of pseudopregnancy was 13 +/- 1 days and, during this time, blood flow was measured by the injection of radioactive microspheres during anesthesia. At autopsy, the corpora lutea were identified and extirpated under a stereomicroscope. These, and the remaining ovary, were then counted for radioactivity and the blood flow was calculated. Progesterone levels were determined in plasma and ovarian tissues. Furthermore, the responsiveness of adenylate cyclase was tested in ovarian tissues at day 6 of pseudopregnancy. An intraarterial injection of hCG (50 IU) or vehicle (saline) was given 20 min before the blood flow determinations in anesthetized rats. The luteal blood flow was not changed by hCG on days 2, 6, and 11 of pseudopregnancy, whereas in the remaining ovary the blood flow increased more than 2-fold, thereby resulting in redistribution of the blood flow. Ten micrograms of NIH-LH-B9, tested at day 6 of pseudopregnancy, mimicked the effect of hCG. At day 6 of pseudopregnancy, hCG (50 IU) was given ip to conscious rats 200 min and 24 h before blood flow determinations. At 200 min after hCG there was a more pronounced redistribution of ovarian blood flow with a 45% reduction in luteal blood flow and a 4-fold increase in flow through the remaining ovary. LH as well as hCG doubled the progesterone content of the remaining ovary. In the corpora lutea an increased progesterone content was seen after 200 min of hCG exposure. At 24 h after hCG injection, all parameters had returned to control levels except that adenylate cyclase was nonresponsive. The increase in the total ovarian blood flow coincides with the increased steroidogenesis and these effects are likely due to release of metabolites and/or vasoactive substances. Despite this increase, the blood flow of the corpus luteum was not increased rendering vascular mechanisms unlikely as a part of the acute LH/hCG effects on corpus luteum of pseudopregnancy.
