Major vessel hemorrhage in endoscopic, endonasal skull-base surgery is a rare but potentially fatal event. Surgical simulation models have been developed to train surgeons in the techniques required to manage this complication. This mixed-methods study aims to quantify the stress responses the model
In the IgG antibody response to bacterial alpha-amylase (B alpha A) assayed by the enzymatic procedure, C3H/He (C3) mice were high and C57BL/6 (B6) mice were low responders. High responsiveness was inherited as a dominant characteristic in (B6XC3)F1 hybrid mice. In these strains, the primary
Aprotinin, a proteinase inhibitor, was evaluated as a pharmacologic aid in dogs subjected to lethal hemorrhagic shock. Survival time, hemodynamic changes, and plasma enzyme analysis were measured as criteria for drug effects. Mixed-breed dogs (n = 14) were divided into 2 groups of 7 each: nontreated

Secretory carcinoma (SC, mammary analogue secretory carcinoma) is a salivary gland tumor with ETV6-NTRK3 gene fusion, and its differential diagnosis includes acinic cell carcinoma (ACC). As hemorrhage is often seen in SC, we hypothesized that magnetic resonance imaging (MRI) and
Purpose: To investigate the correlation between salivary stress markers chromogranin A (CgA), cortisol, α-amylase, β-endorphin and clinical parameters of periodontitis, including sulcus bleeding index (SBI), periodontal probing depth (PD)
Continuous production of extracellular recombinant protein using a previously reported periplasmic protein-release system was successfully demonstrated. The performance of the protein-releasing system was studied using two types of reactor configuration: a conventional chemostat and a chemostat with
Ischemia as a causative factor for acute pancreatitis has been discussed for decades but has only recently gained wider acceptance. Chronic pancreatitis, however, has rarely been attributed to ischemic injury. While experimental evidence is available for the ischemic pathogenesis of acute
HES are high-polymeric glucose compounds obtained via hydrolysis and subsequent hydroxyethylation from the highly-branched amylopectin contained in maize. Initially, the HES were only characterized by their in vitro molecular weight (Mw), without consideration of the in vivo hydrolysis by
In experimental models of pancreatitis lipid peroxidation products are increased possibly because of an enhanced generation of oxygen radicals. The purpose of this study was to determine whether lipid peroxidation products are increased in pancreatic tissue and serum of patients suffering from
This study has traced the behavior of rat anionic trypsin-like immunoreactivity and pancreatic secretory trypsin inhibitor (PSTI) immunoreactivity in the serum of rats undergoing bile-pancreatic duct infusions of buffered solutions with and without the addition of the bile salt taurocholate.
OBJECTIVE
The role of adenosine and its receptors in acute pancreatitis remains unelucidated. The aim was to evaluate the effects of the adenosine A2a receptor agonist and antagonist in the severe, taurocholate-induced experimental acute pancreatitis (EAP).
METHODS
The experiments were performed on
Acute pancreatitis is an inflammatory disease characterized by pancreatic tissue edema, acinar cell necrosis, hemorrhage and inflammation of the damaged gland. It is believed that acinar cell injury is initiated by the activation of digestive zymogens inside the acinar cells, leading finally to the
The indications, pharmacology, adverse reactions, clinical studies, dosage, and cost of hetastarch are reviewed. Hetastarch is a plasma volume expander used in adults for the treatment of shock caused by hemorrhage, burns, surgery, sepsis, or other trauma. It is a heterogenous macromolecular agent
Acute pancreatitis (AP) is an inflammatory disease characterized by tissue edema, necrosis and hemorrhage. The mortality rate associated with this disease is particularly high when the inflammation has become systemic. Recently, activation of the pancreatic renin-angiotensin system (RAS) was shown
In the present work the effect of intramuscular administration of 30.000, 50.000 and 100.000 IU of vitamin A palmitate daily for seven days, respectively, on the liver enzyme activity in 45 white male Wistar rats, aged 12 weeks and weighing 180-200 g, have been studied. The group control was
