Panax notoginseng saponin (PNS) is the main active gradient of Chinese traditional medicine Panax notoginseng. Although its prominent therapeutic efficacy has been demonstrated by various researchers, the broader application is restricted by the low bioavailability of PNS. This article aims to discuss PNS's plasma pharmacokinetics after oral administration of bio-adhesive tablet of PNS to beagl...

This study investigated the effect of Panax notoginseng saponins (PNS) on acute lung injury (ALI) induced by oleic acid (OA) and lipopolysaccharide (LPS). A total of 28 Wistar rats were divided into four groups: sham; sham + PNS; OA‑LPS‑induced ALI and ALI + PNS. Lung tissue histology, lung wet‑to‑dry (W/D) weight ratio, extravascular lung water (EVLW) and epithelial sodium channel α (αENaC) mR...

PNS use refers to the administration of steroids to VLBW infants to prevent and/or treat Chronic Lung Disease (CLD). The rationale for their use is based on their anti-inflammatory actions (Groneck1993). The terms: steroids and corticosteroids are confusingly used as a shorthand for one agent: dexamethasone or to refer to a variety of differing corticosteroid agents. However, almost all of the ...

BACKGROUND Although persistent negative symptoms (PNS) are known to contribute significantly to poor functional outcome, they remain poorly understood. We examined the heuristic value of various PNS definitions and their respective prevalence in patients with first episode psychosis (FEP). We also contrasted those definitions to the Proxy for the Deficit Syndrome (PDS) to identify deficit syndr...

Maternal social stress during late pregnancy programs hypothalamo-pituitary-adrenal (HPA) axis hyper-responsiveness to stressors, such that adult prenatally stressed (PNS) offspring display exaggerated HPA axis responses to a physical stressor (systemic interleukin-1β; IL-1β) in adulthood, compared with controls. IL-1β acts via a noradrenergic relay from the nucleus tractus solitarii (NTS) to c...

OBJECTIVE This study sought to examine the relationship between pseudoneurological symptoms (PNS) and somatic and psychiatric symptom severity, physical functioning, and psychiatric comorbidity. METHODS Interview and questionnaire data were obtained from 120 patients with somatization who participated in a study assessing the efficacy of cognitive-behavioral therapy. Measures elicited informa...

This study investigated the role of the hypogastric nerve and β-adrenergic mechanisms in the inhibition of nociceptive and non-nociceptive reflex bladder activity induced by pudendal nerve stimulation (PNS). In α-chloralose-anesthetized cats, non-nociceptive reflex bladder activity was induced by slowly infusing saline into the bladder, whereas nociceptive reflex bladder activity was induced by...

The aim of the present study was to investigate whether the four guanosines (4G)/five guanosines (5G) polymorphism in the gene coding for plasminogen activator inhibitor-1 (PAI-1) affects the clinical features of primary nephrotic syndrome (PNS). A cohort of 200 biopsy-diagnosed PNS patients was studied, with 40 healthy subjects as controls. The PAI-1 gene polymorphism was detected by polymeras...

A sample of 27 planetary nebulae (PNs) in the Small Magellanic Cloud (SMC) have been observed with theHubble Space Telescope Imaging Spectrograph (HST/STIS) to determine their morphology, size, and the spatial variation of the ratios of bright emission lines. The morphologies of SMC PNs are similar to those of LMC and Galactic PNs. However, only a third of the resolved SMC PNs are asymmetric, c...

BACKGROUND Endothelial progenitor cells (EPCs) derived from the bone marrow (BM) play a key role in the homeostasis of vascular repair by enhanced reendothelialization. Panax notoginseng saponins (PNS), a highly valued traditional Chinese medicine, has been shown to reduce morbidity and mortality from coronary artery disease. The present research was designed to explore the contribution of prog...
