The present results further confirm the usefulness of the push-pull cannula to study the in vivo activity of several neural systems in conscious, freely moving animals. However, it is evident that the inflammatory reaction to the local injury induced by the cannula may have different consequences in the function of a particular brain area. In the caudate nucleus, the responsiveness of the dopaminergic terminals of the nigrostriatal DA system to local infusion of AMPH was clearly reduced after… 
In vivo neurotransmitter levels in the anterior pituitary of freely behaving intact and castrated male rats determined with push-pull perfusion and high pressure liquid chromatography coupled with electrochemical detection.
TLDR
Results demonstrate that the push-pull perfusion technique can be used to measure neurotransmitter levels in the anterior pituitary lobes of living rats, and after castration a distinct rise in norepinephrine and epinephrine accompanied by a decrease in dopamine was clearly detected, suggesting that these neurotransmitters may play an important role directly at the pituitaries.
Norepinephrine Plays an Important Role in Antinociceptive Modulation of Hypothalamic Paraventricular Nucleus in the Rat
TLDR
The data suggested that endogenous NE, not epinephrine, 5-HT, Ach, GABA, and L-glutamate acid played an important role in the PVN antinociceptive modulation.

Involvement of Olfactory Bulb Catecholamines and Luteinizing Hormone‐Releasing Hormone in Response to Social Stimuli Mediating Reproductive Functions a
TLDR
Norepinephrine output was obtained from all males and demonstrated marked increases in response to the introduction of a receptive female, suggesting that this neurotransmitter may be an important component for processing chemical cue information within the OB.
Coital and estrogen signals: a contrast in the preovulatory neuroendocrine networks of rabbits and rhesus monkeys.
TLDR
It is suggested that the brainstem is an extra-hypothalamic site where preovulatory signals for GnRH surges are developed in both rabbits and primates.

In vivo output of dopamine and metabolites from the rat caudate nucleus as estimated with push-pull perfusion on-line with HPLC-EC in unrestrained, conscious rats. I. Chromatographic and biological validation.
In the present experiment we used push-pull perfusion (PPP) on-line with high performance liquid chromatography with electrochemical detection (HPLC-EC) to measure the concentration of neuroactive
Inhibition of ovulation in the rabbit by the adrenergic-blocking agent dibenamine.
TLDR
It is concluded that the pathway of excitation from the hypothalamus to the anterior lobe of the hypophysis was probably not through thehypothalamico-hypophyseal nerve tract, but through the central nervous system.
In-vivo activity of the LH-releasing hormone pulse generator in castrated and intact male rats.
TLDR
The results indicate that the raised blood levels of LH in long-term castrated rats do not appear to be the consequence of high amplitude and high overall release of LHRH.
In vivo release of luteinizing hormone-releasing hormone estimated with push-pull cannulae from the mediobasal hypothalami of ovariectomized, steroid-primed rats.
The in vivo release of LHRH from the mediobasal hypothalami (MBH) of conscious, freely moving rats was estimated by means of a push-pull perfusion system. The effects of local 15-mM K+ infusions as
In vivo electrochemical detection of catechols in the neostriatum of anaesthetized rats: dopamine or DOPAC?
TLDR
The DPV method used in conjunction with an electrochemical treatment of this electrode yields stable and reproducible peaks in which catecholamines and AA are resolved from each other, suggesting that the technique may be a useful means of following dopaminergic activity in vivo.
Prostaglandin E2-induced release of LHRH into hypophysial portal blood(1).
TLDR
Prostaglandin E2 was found to be a potent stimulator of LH release, but larger quantities were needed to stimulate the release of FSH or prolactin and portal vessel infusion studies do not support a direct stimulatory effect of PGE2 on the pituitary gonadotrophs.
Luteinizing hormone-releasing hormone release during the rat estrous cycle and after ovariectomy, as estimated with push-pull cannulae.
A push-pull perfusion (PPP) system was used to carry out the first examination of LHRH release from the mediobasal hypothalami (MBH) of conscious, freely moving rats during stages of the estrous (E)
Simultaneous measurement of luteinizing hormone-releasing hormone and luteinizing hormone release in unanesthetized, ovariectomized sheep.
TLDR
These experiments demonstrate that 1) hypothalamic LHRH release in the Ovx ewe occurs in discrete pulses, with a mean interpulse interval of 38.7 +/- 1.5 min, and 2) LH pulses invariably are preceded or accompanied by LhrH pulses, and 3) LH pulse amplitude is highly correlated with L HRH pulse amplitude.
Evidence for Involvement of α-Adrenergic Receptors in Norepinephrine-Induced Prostaglandin E
Studies were conducted to determine if the stimulatory effect that norepinephrine (NE) exerts on the release of prostaglandin E2 (PGE2) and LHRH from the median eminence is mediated by α- or
Male rats secrete luteinizing hormone and testosterone episodically.
TLDR
Intermittent, short term fluctuations in peripheral levels of LH and testosterone represent the blood-borne, gland to gland signals controlling hypothalamic-pituitary-testicular function in the normal rat.
