Sepsis initiates a neuroinflammatory cascade that contributes to spinal cord inflammation and behavioral impairment, and Toll-like receptor 4 (TLR4) is an important mediator of this cascade. In this study, we tested the hypothesis that ulinastatin (ULI) inhibits sepsis-induced spinal inflammation to alleviate peripheral neuromuscular dysfunction through the TLR4/myeloid differentiation factor 88 (MyD88)/NF-κB signaling pathway. Muscular function, spinal cord water content, and cytokine levels of spinal cord were tested in TLR4-inhibited rats subjected to cecal ligation and puncture (CLP)...

Antimicrotubulin chemotherapeutic agents such as vincristine (VCR), often induce peripheral neuropathic pain. It is usually permanent and seriously harmful to cancer patients' quality of life and can result in the hampering of clinical treatments. Currently, there is no definitive therapy, and many of the drugs approved for the treatment of other neuropathic pain have shown little or no analgesic effect. It is therefore vital to find new and novel therapeutic strategies for patients suffering from chemotherapeutic agent-induced neuropathic pain to improve patients' quality of life...

The aim of this study to investigate the effect of ulinastatin (UTI) on lipopolysaccharide (LPS) -induced injury of cardiac micro vascular endothelial cell, and explore potential mechanisms Primary cardiac micro vascular endothelial cells were harvested from neonatal Sprague Dawley rats. Cardiac micro vascular endothelial cells were prepared for further treatment after subculture. The experiment was designed into 4 groups: Control group, LPS (0.1U/ml) group, UTI (100U/ml) group and (UTI+LPS) group. MTT assay and scratch test were performed to assess cell viability of cardiac micro vascular endothelial cells...

Ulinastatin, a serine protease inhibitor, which has anti-inflammatory properties and neuroprotective effects, is used to treat acute inflammatory disorders. Recent evidence indicates that administration of ulinastatin alleviates pain in rat model of neuropathic pain (NPP). However, its effect on NPP and the underlying mechanism requires further study. In this study, we evaluated the role of intrathecal administration of ulinastatin in rats with sciatic nerve ligation and observed the effect of ulinastatin on the ATP/P2Y2 receptor pathway...

BACKGROUND: Robot-assisted laparoscopic partial nephrectomy (RLPN) is an emerging technique for treating small renal masses. Although RLPN has many advantages, ischemic kidney injury is inevitable during renal artery clamping. The overall incidence of acute kidney injury (AKI) after partial nephrectomy has been reported to be up to 39%. Moreover, effective pharmacological protection against AKI after partial nephrectomy has not yet been demonstrated. Ulinastatin has been shown to protect the kidney from ischemia/reperfusion injury via its anti-inflammatory and anti-oxidant activities...

However, the effects of intraintestinal administration of UTI on intestinal and multiple organ damage in sepsis have not been reported. MATERIALS AND METHODS: In this study, we established a sepsis model in rats using cecal ligation and puncture and compared the effects of intraintestinal administration of UTI through an artificial fistula of duodenum and intraperitoneal administration of UTI on the pathophysiological changes of sepsis...

Ulinastatin, is a broad-spectrum protease inhibitor purified from human urine, inhibits endogenous proteases such as trypsin, α-chymotrypsin, hyaluronidase, and plasmin. It is widely being used at increasingly higher doses for the treatment of acute or chronic pancreatitis, severe infection, and acute organ failure. We aimed to evaluate the safety and tolerability of high-dose ulinastatin in healthy volunteers in our single center, randomized, double-blind, placebo-controlled, single-dose escalation study...

Burns is a global health problem with significant morbidity and mortality. Ulinastatin, a serine protease inhibitor, has the potential to improve outcomes in burns. A retrospective comparative case note review analysis was performed to assess the impact of ulinastatin on the outcomes in acute burns patients. Acute burns patients, admitted to Masina hospital, Mumbai, from October 2012 to April 2015, who received ulinastatin, were identified from the hospital records. A similarly sized cohort of patients, admitted before the introduction of ulinastatin, was also identified...

BACKGROUND: Ulinastatin or urinary trypsin inhibitor (UTI) has been shown to ameliorate the inflammatory response induced by experimental severe acute pancreatitis (SAP) and hence reduce the mortality, however the mechanism of its action remains incompletely understood. We have investigated the effect of ulinastatin on regulatory T-cells (Tregs) in an established rat model of SAP. METHODS: We established a rat SAP model by injecting 5% Na-taurocholate into the pancreatic duct and treated the SAP rats with ulinastatin with different dose level (5000, 10000, 30000 U/kg) through intraperitoneal injection at 0, 6 and 12 h...

OBJECTIVE: Ulinastatin reduces the high permeability of vascular endothelial cells induced by tumor necrosis factor alpha (TNF-α). This study investigated the molecular mechanism behind this effect, with the aim of understanding the action of ulinastatin in sepsis therapy and exploring novel therapeutic strategies for sepsis patients. METHODS: A TNF-α treated human umbilical vein endothelial cell line (EA.hy926) was employed as an inflammation model. Horseradish peroxidase permeability assays and an epithelial voltmeter method were used to measure the permeability of EA...

OBJECTIVE: To investigate the effect of ulinastatin (UTI) for early drug intervention on the serum levels of tumor necrosis factor-α (TNF-α), P-selectin, and thrombin-antithrombin complex (TAT) in young rats with sepsis. METHODS: A total of 120 male rats aged 4 weeks were randomly divided into normal control group, sham-operation group, sepsis group, low-dose UTI group (50 000 U/kg), and high-dose UTI group (200 000 U/kg), with 24 rats in each group. Modified cecal ligation and puncture was performed to establish a rat model of sepsis, and the rats in the low- and high-dose UTI groups were given caudal vein injection of UTI after model establishment...

BACKGROUND: Inflammatory damage plays an important role in ischemic stroke and provides potential targets for therapy. Ulinastatin (UTI), a drug used to treat shock and acute pancreatitis in clinic, has attracted attention for its protective effects through immunomodulatory and anti-inflammatory properties. However, the effect of UTI in the acute phase of cerebral ischemia/reperfusion (I/R) is not clear. This study is to investigate the potential neuroprotective effect of UTI and explore its underlying mechanisms...

Ulinastatin has been demonstrated to protect against heatstroke by reducing cerebral ischemia and damage in rats. In order to extend these observations, apoptosis and systemic inflammatory responses were assessed in rats treated with ulinastatin prior to the initiation of heatstroke. Following the onset of heatstroke, histological analysis revealed that the hippocampal tissues displayed edema and damage. In addition, upregulation of malondialdehyde, inducible nitric oxide synthase (iNOS) and reactive oxygen species and downregulation of superoxide dismutase were observed compared with the respective levels in the control group...

PURPOSE: To assess the effects of urinary trypsin inhibitor (UTI) ulinastatin combined with thymosin alpha1 (Tα1) on sepsis. MATERIALS AND METHODS: The meta-analysis included 8 randomized controlled trials (N=1112 patients) on UTI-based therapy for sepsis published before July 10, 2016. Two investigators independently extracted data and assessed the quality of each study. The short-term mortality rate, duration of mechanical ventilator and vasopressor use, length of intensive care unit stay, Acute Physiology and Chronic Health Evaluation (APACHE) II score, and differences in inflammatory cytokines (interleukin [IL]-6, IL-10, and tumor necrosis factor α) were assessed using statistical software...
