A membrane fraction enriched in parathyroid hormone (PTH)-sensitive adenylate cyclase and sodium and potassium ion-activated (Na+, K+)-ATPase was prepared from bovine kidney. Tritiated PTH binding to this membrane fraction was dependent on both hormone and membrane protein concentration. Both total and specific binding of the hormone decreased significantly after 5 to 10 min of incubation at 22 degrees. PTH binding was highly specific, being sensitive to inhibition only with active forms of unlabeled hormone (native and 1-34 PTH). Specific binding showed a pH optimum of 7.3 to 7.5. Inhibition of binding of tritiated hormone by unlabeled PTH was also highly effective at pH 6.0, but this apparently specific binding was also inhibited by
adrenocorticotropic hormone
, insulin, glucagon, and
vasopressin
. Dissociation of bound hormone was demonstrated, and an apparent dissociation constant of 4.6 X 10(-2) min-1 was obtained. Specific binding was eliminated by pretreatment of the membranes with trypsin. The concentration dependence for inhibition of binding with unlabeled PTH was identical to that for activation of adenylate cyclase in this membrane preparation, and binding was also inhibited by concentrations of calcium in the 0.5 to 2 mM range.

The syndrome of inappropriate secretion of
antidiuretic hormone
has been associated with many pulmonary diseases, including tuberculosis and bacterial and viral pneumonia: however, it has not been reported with anaerobic infections or empyema in the absence of pneumonia. We report a patient with empyema due to Bacteroides melaninogenicus, Bacteroides oralis, and Peptostreptococcus who developed the syndrome. Eight hours before the start of therapy, his serum sodium concentration was 127 mEq per liter; serum osmolality, 255 mOsm per kg; urine osmolality, 522 mOsm per kg; urinary sodium concentration, 39 mEq per liter. The creatinine clearance and the
adrenocorticotropic hormone
stimulation test were normal, and there was no evidence of dehydration. No other causes of the syndrome of inappropriate secretion of
antidiuretic hormone
were apparent. With drainage and antimicrobial drug therapy, the empyema cleared, and the syndrome resolved in 8 days. The patient has been well, without evidence of inappropriate secretion of
antidiuretic hormone
, for 9 months. Anaerobic infections and/or empyema without pneumonia can be associated with the syndrome of inappropriate secretion of
antidiuretic hormone
.

Simultaneous measurements of both beta-melanocyte stimulating hormone (beta-MSH) and adrenocorticotropic hormone (ACTH) in extracted plasma were performed by specific radioimmunoassays. During insulin-induced hypoglycemia, there was a marked increase of plasma
ACTH
levels and a slight but significant increase of plasma beta-MSH levels. Lysine-
vasopressin
on the other hand, caused a significant rise of plasma
ACTH
levels without corresponding response of plasma beta-MSH. Following glucagon administration, neither hormone rose significantly. However, metyrapone infusion caused a significant increase of both
ACTH
and beta-MSH levels, and frequent blood sampling revealed that both hormones were secreted episodically, and that peaks generally coincided with each other. These data suggest that the secretion of these two hormones can occur together in most instances, and that the same mechanism is involved in the secretion of both hormones under the negative feedback control.

Four open, dry Holstein cows in the University of Missouri Climatic Laboratory were used to study the effect of
adrenocorticotropic hormone
administration on glucocorticoids and
antidiuretic hormone
of plasma in two reversal trials at thermoneutral (20 C, 50% relative humidity) and heat (33 C, 50% relative humidity) conditions. Average glucocorticoids (saline versus
adrenocorticotropic hormone
) at thermoneutral were 8.3 and 41.2 ng/ml while values for heat were 6.2 and 40.4 ng/ml. The effect of heat on glucocorticoids of plasma was not significant. Injection of
adrenocorticotropic hormone
under thermoneutrality and heat caused a marked increase in
antidiuretic hormone
within 5 min which lasted to 120 min. At thermoneutral average
antidiuretic hormone
levels (saline versus
adrenocorticotropic hormone
) were .5 and 1.9 pg/ml while values for heat were 1.8 and 3.6 pg/ml. Antidiuretic hormone concentrations under heat were higher than thermoneutral in cows injected with saline and andrenocorticotropic hormone. The fast response of
antidiuretic hormone
of plasma to exogenous
adrenocorticotropic hormone
suggests that
adrenocorticotropic hormone
might act directly at higher levels of the central nervous system causing release of
antidiuretic hormone
.

beta-Endorphin is not detectable in plasma from normal human subjects when measured under baseline conditions or after the subjects have received
vasopressin
, an agent that elevates beta-lipotropin and adrenocorticotropic hormone (ACTH). Significant amounts of beta-endorphin are present in plasma of patients with endocrine disorders associated with increased
ACTH
and beta-lipotropin production. Highly purified, natural beta-lipotropin is not peripherally converted to beta-endorphin in vivo in normal subjects.

A 52-year-old woman experienced hypoadrenalism (mean 8 AM plasma cortisol level, 3.7 microgram/dL) after hypothalamic surgery and radiotherapy for craniopharyngioma. Despite low plasma
adrenocorticotropic hormone
levels (less than 25 pg/mL), absent diurnal variation of the plasma cortisol level, and subnormal urinary 17-hydroxycorticosteroid response to metyrapone, she had normal plasma cortisol responses to insulin-induced hypoglycemia and to administration of
vasopressin
or synthetic
adrenocorticotropic hormone
. Stress-induced cortical release may be preserved despite notable abnormalities in regulation of cortisol secretion by diurnal and feedback-mediated mechanisms.

Male mice were given a single injection of either adrenocorticotropic hormone (ACTH) or lysine
vasopressin
immediately after a defeat in an encounter with an aggressive male mouse. The defeated mice were tested for submissiveness at either 24 hours, 48 hours, or 7 days after the initial encounter. Both hormone treatments increased future submissiveness, although the time courses of the effects were different: The effects of
ACTH
disappeared after 48 hours, whereas those of
vasopressin
persisted for 7 days. These results suggest that changes in peptide hormone levels following naturally stressful experiences can affect the memory of those experiences, as expressed in future adaptive responses.

Electroconvulsive therapy (ECT) is an extremely effective treatment for a variety of psychiatric syndromes. However, it is frequently associated with transient cognitive side effects. Recent research has shown that these effects are sensitive to a number of treatment parameters, such as electrode placement and stimulus dosage, that the clinician may manipulate. However there have been relatively few efforts to determine if these cognitive side effects may be reduced or prevented by psychopharmacological intervention. In animals electroconvulsive shock (ECS) has been used frequently to screen for compounds which may improve cognition and memory. This paper reviews basic research studies on such compounds, as well as clinical trials in the treatment of various cognitive disorders. Studies using such compounds to reduce the cognitive side effects of ECT are exhaustively reviewed. The compounds that have been examined include: opioids,
vasopressin
,
adrenocorticotropic hormone
, other neuropeptides, cholinergic agents, nootropic agents, ergoloid mesylates, calcium-channel blockers, dexamethasone, thyroid hormone, and stimulants.

We investigated effects of corticotropin-releasing hormone (CRH), lysine
vasopressin
and interleukin (IL)-1 beta[1-148], a less pyrogenic analog of human IL-1 beta, on the hypothalamo-pituitary-adrenal axis in a rat model of secondary adrenocortical insufficiency. After 2 weeks of corticosterone 21-sodium succinate treatment, hypothalamic CRH, anterior pituitary adrenocorticotropic hormone (ACTH) and the adrenal weight of the rats decreased significantly and their plasma
ACTH
showed a significantly smaller response to ether stress, as did plasma corticosterone level. A mixed solution of CRH (10 micrograms) and lysine
vasopressin
(2 micrograms) or recombinant human IL-1 beta[1-148] (1 micrograms), administered to these rats for 7 days, apparently accelerated the recovery of the pituitary and adrenocortical responsiveness to ether stress and significantly increased the recovery rate of anterior pituitary
ACTH
contents and adrenal weight. The IL-1 beta analog also increased hypothalamic CRH. These data indicated that, in a rat model with glucocorticoid-induced adrenocortical insufficiency, synthesis and release of hypothalamic CRH, pituitary
ACTH
and adrenal glucocorticoid were all considerably affected. CRH combined with lysine
vasopressin
or a less pyrogenic IL-1 beta analog, when administered to these rats, accelerated the recovery of the pituitary and the adrenocortical functions significantly, suggesting the potential clinical usefulness of these peptides.

The purpose of these studies was, first, to determine whether hypertonic saline (HS) infusion or nitroprusside (NiPr)-induced hypotension augments the
vasopressin
(AVP) and adrenocorticotropic hormone (ACTH) responses to insulin (Ins)-induced hypoglycemia and, second, to determine whether neurohypophysectomy could attenuate the augmentation. Conscious, male dogs (n = 8) underwent two different types of experiments. In the first, Ins was preceded by either a 30-min infusion of normal saline (control) or HS to raise plasma osmolality and AVP. HS augmented the AVP response but diminished the
ACTH
response to Ins. In the second group of experiments, Ins was preceded by a controlled decrease in mean arterial pressure using NiPr, which led to an increase in AVP and
ACTH
. The initial
ACTH
and AVP response to Ins was augmented by NiPr, but this early augmentation was not sustained. Neurohypophysectomy attenuated the early augmentation of the
ACTH
response to Ins by NiPr, but did not alter the final
ACTH
level achieved. We conclude that HS augmented the AVP but inhibited the
ACTH
response to Ins probably because of expansion of plasma volume. Concomitant hypotension led to an augmentation of the early but not sustained AVP and
ACTH
response to Ins. Neurohypophysectomy eliminated this augmentation, suggesting a role for AVP from the neural lobe in the early
ACTH
response to combined hypotension and Ins-induced hypoglycemia.
