Many studies have demonstrated that the ventrolateral medulla (VLM) plays an important role in the maintenance of systemic arterial pressure (SAP) and vascular tone. The VLM is divided into rostral (RVLM) and caudal (CVLM) portions which play opposin

Dexamethasone is an effective antiemetic drug, but its mechanism of action is unclear. We designed this study to investigate the direct antiemetic action of dexamethasone in the medulla of cats. By using an oscillographic vomiting model, decerebrated

Nitric oxide (NO) is synthesized from L-arginine by NO synthase (NOS). NO stimulates the soluble form of guanylyl cyclase (sGC) and induces accumulation of cyclic guanosine monophosphate (cGMP). The purpose of this study was to examine whether the ca

In 20 urethane-anaesthetised cats, microinjection of N -methyl- d -aspartate (NMDA) into the intermediate-lateral (IL-) or the dorsolateral (DL-) periaqueductal grey areas (PAG) of the midbrain elicited similar patterns of cardiovascular responses: i
Dorsomedial medulla is more susceptible than rostral ventrolateral medulla to hypoxic insult in cats

We investigated the responses of systemic arterial pressure and vertebral sympathetic nerve activity to glutamate microinjections (0.1 M, 70 nl) in the dorsomedial (DM) and the rostral ventrolateral medulla (RVLM) before hypoxia and after reoxygenati

In 35 adult cats anesthetized with intraperitoneal chloralose and urethane, the ventrolateral medulla was explored by microinjection of kainic acid (KA, 24 mM, 200 nl) with metal electrode-tubing or glass micropipette to determine regions which elici

Phrenic motoneurons (PMNs) receive intermittently glutaminergic inspiratory drives and GABAergic inhibition in adult mammals. Since gamma-amino-butyric acid (GABA) might act as an excitatory amino acid in early stages of development, we here investig

The functional correlation of the depressor caudal ventrolateral medulla (CVLM) with the two pressor regions, i.e. rostral ventrolateral medulla (RVLM) and dorsomedial medulla (DM), and with another inhibitory region, i.e. the paramedian reticular nu

In vivo electrochemical detection was employed to examine iron-induced oxidative injury on dopamine dynamics in the nigrostriatal system of urethane-anesthetized rats. Seven days after an intranigral infusion of iron, oxidative stress was confirmed b

1. Fifty-five intact and six baroreceptor denervated and vagotomized cats of either sex were anaesthetized intraperitoneally with urethane (400 mg/kg) and alpha-chloralose (40 mg/kg). Responses of the systemic arterial pressure (SAP), mean SAP (MSAP)
