Lipińska S., Szkudlarek U., Traczyk W. Z.: Hypophysial portal blood flow during preganglionic stimulation of the superior cervical ganglion under condition of systemic arterial blood pressure stabilization in rat. Acta Physiol. Pol. 1990, 41(1-3): 53-61. The presence of hypothalamic hormones in the pituitary portal blood is regarded as the principal factor by which the hypothalamus controls pituitary secretion. In contrast to numerous investigations on hypothalamic hormone release, the regulation of the hypophysial-portal blood flow (HPBF) has been scarcely studied. Hypophysial-portal vessels were exposed according to the Worthington’s method [1966]. The 10-min blood samples were collected before and during unilateral or alternative bilateral electrical stimulation of the preganglionic fibers of the superior cervical ganglia (SCG). During blood samples collection the stable systemic arterial blood pressure was maintained by a barostat. The HPBF was estimated according to the determination of the hemoglobin in samples of washed and collected blood from the cut pituitary portal vessels. The mean HPBF was 3.5 μ /min. Electrical stimulation of SCG. did not change HPBF. This indicates that sympathetic efferents do not participate in the regulation of HPBF under conditions of stabilization of the systemic arterial blood pressure.

Caerulein-induced acute pancreatitis was studied in rats. Consistent with this type of acute pancreatitis morphological (edema, leukocytic infiltration and acinar cell vaculization) and biochemical (increase in pancreatic protein content, PAF release and serum amylase) changes developed 5 hours after caerulein administration. In addition increase in pancreatic weight and decrease in pancreatic blood flow were noticed. PAF administration caused pancreatic damage similar in some parameters to caerulein-induced pancreatitis, along with reduction of pancreatic blood flow, increase in pancreatic protein content, and serum amylase. TCV-309, a selective PAF antagonist, administered prior to caerulein and/or PAF, reduced caerulein-induced pancreatitis and prevented PAF-induced pancreatitis. Results of our present studies indicate the crucial role of PAF in pathogenesis of experimental acute pancreatitis.

The mesenteric circulation is regulated by multiple mechanisms, there is sufficient reason to support the suspicion that local metabolic factors are especially important in the control of intestinal vasculature. Of these, adenosine, a purine nucleoside and mesenteric vasodilator, may be the messenger of the intenstinal tissue to signal appropriate responses of the intestinal vessels. The evidence supporting the candidacy of the nucleoside as a local regular of mesenteric circulation may be summarized, as follows: Adenoside is present in the tissue of the gut in measurable quantities. Exogenous adenosine is a powerful dilator of mesenteric resistance vessels. Blockade of adenosine receptors in the mesenteric circulation interferes significantly with three autoregulatory phenomena, i. e., postprandial hyperemia, pressure-flow autoregulation, and reactive hyperemia. The evidence which weakens the role of adenosine as mesenteric vasoregulator includes: Findings in several reports that adenosine depressed intenstinal oxygen consumption. The failure of adenosine receptors to inhibit some autoregulatory hyperemias of the gut and the rather limited amount of evidence regarding tissue adenosine release in autoregulatory responses of the gut’s vasculature.

The endothelium is a highly active organ responsible for vasculatory tone and structure, angiogenesis, as well as hemodynamic, humoral, and inflammatory responses. The endothelium is constantly exposed to blood flow, sheer stress and tension. Endothelial cells are present as a vasculature in every tissue of the body and react to and control its microenvironment. A variety of ion channels are present in the plasma membranes of endothelial cells. These include potassium channels such as inwardly rectifying potassium (Kir) channels, voltage-dependent (Kv) channels, ATP-regulated potassium (KATP) channels and three types of calcium-activated potassium channels (KCa), the large (BKCa), intermediate (IKCa), and small (SKCa) -conductance potassium channels. Potassium current plays a critical role in action potentials in excitable cells, in setting the resting membrane potential, and in regulating neurotransmitter release. Mitochondrial isoforms of potassium channel contribute to the cytoprotection of endothelial cells. Prominent among potassium channels are families of calcium-activated potassium channels, and especially large-conductance calcium-activated potassium channels. The modulation of BKCa channels, which are voltage- and calcium-dependent, has been intensively studied. The BKCa channels show large expression dynamics in endothelial cells and tissue-specific expression of large numbers of alternatively spliced isoforms. In this review, a few examples of the modulatory mechanisms and physiological consequences of the expression of BKCa channels are discussed in relation to potential targets for pharmacological intervention.
