Urinary trypsin inhibitor (UTI), a serine protease inhibitor, has been widely used as a drug for patients with acute inflammatory disorders such as disseminated intravascular coagulation, shock, and pancreatitis. However, direct contribution of UTI to inflammatory diseases has not been established. The present study analyzed acute inflammatory lung injury induced by lipopolysaccharide (LPS) in UTI-deficient (-/-) mice and corresponding wild-type (WT) mice. UTI (-/-) and WT mice were treated intratracheally with vehicle or LPS (125 mug/kg). The cellular profile of bronchoalveolar lavage fluid, lung water content, histology, and expression of proinflammatory molecules in the lung were evaluated. After LPS challenge, both genotypes of mice revealed neutrophilic lung inflammation and pulmonary edema. UTI (-/-) mice, however, showed more prominent infiltration of inflammatory cells and edema than WT mice. After LPS challenge in both genotypes of mice, the lung levels of mRNA and/or protein expression of interleukin-1beta, macrophage inflammatory protein-1alpha, macrophage chemoattractant protein-1, keratinocyte chemoattractant, and intercellular adhesion molecule-1 (ICAM-1) were elevated in both groups, but to a greater extent in UTI (-/-) mice than in WT mice. These results suggest that UTI protects against acute lung injury induced by bacterial endotoxin, at least partly, through the inhibition of the enhanced local expression of proinflammatory cytokines, chemokines, and ICAM-1.

Heat exhaustion and heatstroke are part of a continuum of heat-related illness. Both are common and preventable conditions affecting diverse patients. Recent research has identified a cascade of inflammatory pathologic events that begins with mild heat exhaustion and, if uninterrupted, can lead eventually to multiorgan failure and death. Heat exhaustion is characterized by nonspecific symptoms such as malaise, headache, and nausea. Treatment involves monitoring the patient in a cool, shady environment and ensuring adequate hydration. Untreated heat exhaustion can progress to heatstroke, a much more serious illness involving central nervous system dysfunction such as delirium and coma. Other systemic effects, including rhabdomyolysis, hepatic failure, arrhythmias, disseminated intravascular coagulation, and even death, are not uncommon. Prompt recognition and immediate cooling through evaporation or full-body ice-water immersion are crucial. Physicians also must monitor electrolyte abnormalities, be alert to signs of renal or hepatic failure, and replace fluids in patients with heatstroke. Most experts believe that physicians and public health officials should focus greater attention on prevention. Programs involving identification of vulnerable individuals, dissemination of information about dangerous heat waves, and use of heat shelters may help prevent heat-related illness. These preventive measures, when paired with astute recognition of the early signs of heat-related illness, can allow physicians in the ambulatory setting to avert much of the morbidity and mortality associated with heat exhaustion and heatstroke.

The present study was undertaken to investigate the antinociceptive, antiinflammatory, and antidiabetic properties of the aqueous leaf extract of Leonotis leonurus (L.) R. BR. (Lamiaceae) in mice and rats, to scientifically appraise some of the plant's ethnomedical uses, and its safety and efficacy. The leaf powder of the plant was Soxhlet extracted with distilled water and used. The antinociceptive effect of the plant's extract was evaluated by the "hot-plate" and "acetic acid" test models of pain in mice, while the antiinflammatory and antidiabetic effects of the leaf extract were investigated in rats, using fresh egg albumin-induced paw edema, and streptozotocin (STZ)-induced diabetes mellitus, respectively. Morphine (MPN, 10 mg/kg i.p.), diclofenac (DIC, 100 mg/kg i.p.), and chlorpropamide (250 mg/kg p.o.) were used, respectively, as reference analgesic, antiinflammatory, and hypoglycemic agents for comparison. L. leonurus leaf aqueous extract (LLE, 50-800 mg/kg i.p.) produced dose-dependent and significant (p < 0.05-0.001) antinociceptive effects against thermally and chemically induced nociceptive pain stimuli in mice. LLE (50-800 mg/kg i.p.) also significantly (p < 0.05-0.001) inhibited fresh egg albumin-induced paw edema, and caused significant (p < 0.05-0.001) hypoglycemic effects in rats. It is suggested that the analgesic effects of LLE (50-800 mg/kg i.p.) may be peripherally and centrally mediated. The different flavonoids, diterpenoids, polyphenolics, and other chemical constituents of the plant may be involved in the observed antinociceptive, antiinflammatory, and antidiabetic effects of the plant's extract. However, the results of this experimental animal study suggest that the aqueous leaf extract of L. leonurus possesses antinociceptive, antiinflammatory, and hypoglycemic properties, and thus lend pharmacological credence to the suggested folkloric uses of the herb in the management and/or control of painful, arthritic, and other inflammatory conditions, as well as for adult-onset, type-2 diabetes mellitus in some communities of South Africa.

The stable carbon isotopic composition of dissolved inorganic carbon (delta13C(DIC)) is traditionally determined using either direct precipitation or gas evolution methods in conjunction with offline gas preparation and measurement in a dual-inlet isotope ratio mass spectrometer. A gas evolution method based on continuous-flow technology is described here, which is easy to use and robust. Water samples (100-1500 microl depending on the carbonate alkalinity) are injected into He-filled autosampler vials in the field and analysed on an automated continuous-flow gas preparation system interfaced to an isotope ratio mass spectrometer. Sample analysis time including online preparation is 10 min and overall precision is 0.1 per thousand. This method is thus fast and can easily be automated for handling large sample batches.

We studied 13 emergency cases of liver abscess. Five cases of septic shock or clouding of consciousness were identified on admission. Six patients had diabetes mellitus. Twelve patients met the diagnostic criteria for systemic inflammatory response syndrome, and nine met the criteria for disseminated intravascular coagulation. Plasma endotoxin levels improved rapidly after drainage. Causative organisms were isolated in all patients, and the most common organism was Klebsiella pneumoniae (seven cases). Percutaneous transhepatic abscess drainage (PTAD) was performed not only in single cases but also in multiple cases with main huge abscesses. Surgical treatment was performed in the following three cases: a ruptured abscess, an ineffective PTAD, and a case of peritonitis after PTAD. Irrigation of abscesses with strong acidic electrolyzed water revealed a significant decrease in treatment duration. In the majority of our cases, severe conditions were identified on admission. Strong acidic electrolyzed water was useful for management of PTAD.

A 23-year-old comatose man was presented in the emergency room. He had been working inside a building under construction on a hot summer's day. His core body temperature was 42.1 degrees C and he was diagnosed with heat stroke. Urgent cooling procedures, including applying cold vapor to the patient's skin, a gastric lavage with cold water and an intravenous cold saline infusion, were not completely successful and his body temperature remained above 40 degrees C. Because his high temperature was refractory to conventional cooling procedures and we suspected that acute renal failure (ARF) by rhabdomyolysis would develop, we applied hemodialysis (HD) using cold dialysate (initially 30 degrees C and later 35 degrees C), followed by continuous hemodiafiltration (CHDF) with cold dialysate (35 degrees C) at a high flow rate of 18,000 mL per hour. The patient's body temperature fell below 38.0 degrees C within 3 h and was kept below 38.0 degrees C. Continuous hemodiafiltration was continued for one week. During the first week, the patient suffered from multiple organ failure (MOF) involving renal failure, as well as the failure of heart, liver, lung, and central nervous systems. Disseminated intravascular coagulation also developed. However, by virtue of cold CHDF, he almost recovered 3 weeks after the onset, except for remaining mild liver and renal dysfunction. In severe heat stroke, cold HD and high flow, cold CHDF should be a therapeutic choice for cooling and treatment of MOF. Considering mild liver and renal dysfunction still remained, this case suggested these procedures should be initiated at the very beginning of the treatment of severe heat stroke.

Previous studies in our laboratories and elsewhere have shown that some members of Anacardiaceae family possess antiinflammatory, analgesic and hypoglycemic effects in man and mammalian experimental animals. The present study was, therefore, undertaken to examine the antiinflammatory, analgesic and antidiabetic properties of the stem-bark aqueous extract of Mangifera indica Linn., M. indica a member of the Anacardiaceae family, in rats and mice. The stem-bark powder of M. indica was Soxhlet extracted with distilled water and used. The analgesic effect of the plant's extract was evaluated by the hot-plate and acetic acid test models of pain in mice, while the antiinflammatory and antidiabetic effects of the stem-bark extract were investigated in rats, using fresh egg albumin-induced paw edema, and streptozotocin (STZ)-induced diabetes mellitus, respectively. Morphine (MPN, 10 mg/kg i.p.), diclofenac (DIC, 100 mg/kg i.p.), and chlorpropamide (250 mg/kg p.o.) were used respectively as reference analgesic, antiinflammatory, and hypoglycemic agents for comparison. M. indica stem-bark aqueous extract (MIE, 50-800 mg/kg i.p.) produced dose-dependent and significant (p<0.05-0.001) analgesic effects against thermally and chemically induced nociceptive pain stimuli in mice. MIE (50-800 mg/kg i.p.) also significantly (p<0.05-0.001) inhibited fresh egg albumin-induced paw edema, and caused significant (p<0.05-0.001) hypoglycemic effects in rats. It is suggested that the analgesic effects of MIE (50-800 mg/kg i.p.) may be peripherally and centrally mediated. The different chemical constituents of the plant, especially the polyphenolics, flavonoids, triterpenoids, mangiferin, and other chemical compounds present in the plant may be involved in the observed antiinflammatory, analgesic, and hypoglycemic effects of the plant's extract. However, the results of this experimental animal study lend pharmacological credence to the suggested folkloric uses of the plant in the management and control of painful, arthritic and other inflammatory conditions, as well as in the management of adult-onset type 2 diabetes mellitus in some rural African communities.

Quinine is widely used for the common symptom of leg cramps. Quinine tablets require a prescription, but quinine and the product from which it is derived, cinchona, are also available without prescription. They are components of over-the-counter remedies for many common symptoms, of nutrition products, and of beverages such as tonic water and bitter lemon. Although quinine has been used for centuries, initially as an extract from the bark of the cinchona tree, allergic reactions to quinine can be severe and can affect multiple organs. These allergic reactions can cause thrombocytopenia, neutropenia, anemia, disseminated intravascular coagulation, acute renal failure, liver toxicity, and neurological abnormalities. Because quinine use is often intermittent, defining quinine as a cause of an acute disorder may be difficult. Moreover, since quinine use is often self-regulated, patients may not mention it in response to direct questions about medication use, adding to diagnostic difficulty. The diversity and severity of quinine-associated disorders and the difficulties of diagnosis are illustrated by the presentation of 4 case histories. Awareness of the variety of potential quinine-associated reactions is important for accurate diagnosis and critical for prevention of recurrent illness.

The quality of both groundwaters and surface waters that arise during flooding of abandoned lignite open pits are influenced by regional and local factors. A typical regional factor is due to oxidised sedimentary sulfides. A more local factor is the interaction of shallow water with highly saline groundwater, which is important in Merseburg-Ost (Germany). Investigation of this system is aided by the use of many environmental isotope tracers but special problems can arise. In order to reveal processes in the mine environment (shallow groundwater, lake water) and to characterise mixtures with saline groundwater results are described using the tracers deltaD, delta18O, delta13C, delta34S, 87Sr/86Sr, 3H, 14C, 39Ar, and 222Rn. Deep highly saline groundwater had a radiocarbon concentration typically below 10 pMC. The values of delta13C(DIC) are around-5 per thousand. As delta13C of the aquifer rock samples (Permian, Zechstein carbonates) was in the range of-6...+5 per thousand, residence time corrections based on delta13C are questionable. Additional checks with 39Ar, as well as results from the variationof delta18O (or deltaD) with respect to the salinity, emphasise a Holocene age; as is also the case for most mineralised groundwaters and also for water having a low delta18O (and deltaD). For saline groundwater residing in the Zechstein aquifer the measured delta34S values of about 12 per thousand are close to those expected from the literature. In contrast, the 87Sr/86Sr ratio of dissolved strontium is far from the values anticipated for the aquifer rocks despite there being proportionality between the chloride concentration and the strontium concentration. Furthermore, the proportionality is not valid in lower mineralised water. The 87Sr/86Sr ratio can, therefore, hardly be used as a tracer for the distribution of ascending saline water. The amount of salt-water coming from below into the residual quarry basins is an essential contribution to the lake inventories. Therefore, 222Rn was used to assist in determining the renewal of salt-water layers that formed in deep lake locations. In the deep zones 222Rn concentrations up to 6 Bq/l were measured but were dominantly in equilibrium with 226Ra, which was found in all higher mineralised groundwater samples. Excess radon was limited to just a few decimetres above the lake sediment surface but does not appear to be caused by continuous groundwater discharge. Hydrochemical investigations of groundwater from the Quaternary aquifer were carried out over the last six years before flooding was complete. Apart from a slight downward shift of the average sulfate concentration, other changes showed virtually no trends. An increase of the sulfate concentration was mostly correlated with a decrease of delta34S for individual sites only, but not for the whole ensemble of sampling locations. Sulfate from pyrite oxidation plays an important role but cannot be attributed unequivocally to coal mining. There are hints that the conditions closer to the basin edges may differ from those remoter parts of the flood plain.

Airway submucosal glands are sites of high expression of the cystic fibrosis transmembrane conductance regulator (CFTR) Cl(-) channel and contribute to fluid homeostasis in the lung. However, the molecular mechanisms of gland ion and fluid transport are poorly defined. Here, submucosal gland serous acinar cells were isolated from murine airway, identified by immunofluorescence and gene expression profiling, and used in physiological studies. Stimulation of isolated acinar cells with carbachol (CCh), histamine or ATP was associated with marked decreases in cell volume (20 +/- 2% within 62 +/- 5 s) that were tightly correlated with increases in cytoplasmic Ca(2+) concentration ([Ca(2+)](i)) as revealed by simultaneous DIC and fluorescent indicator dye microscopy. Simultaneous imaging of cell volume and the Cl(-)-sensitive fluorophore SPQ indicated that the 20% shrinkage was associated with a fall of [Cl(-)](i) from 65 mm to 28 mm, reflecting loss of 67% of cell Cl(-) content, accompanied by parallel efflux of K(+). Upon agonist removal, [Ca(2+)](i) relaxed and the cells swelled back to resting volume via a bumetanide-sensitive Cl(-) influx pathway, likely to be NKCC1. Accordingly, agonist-induced serous acinar cell shrinkage and swelling are caused by activation of solute efflux and influx pathways, respectively, and cell volume reflects the secretory state of these cells. In contrast, elevation of cAMP failed to elicit detectible volume responses, or enhance those induced by submaximal [CCh], because the magnitude of the changes were likely to be below the threshold of detection using optical imaging. Finally, when stimulated with cholinergic or cAMP agonists, cells from mice that lacked CFTR, as well as wild-type cells treated with a CFTR inhibitor, exhibited identical rates and magnitudes of shrinkage and Cl(-) efflux compared with control cells. These results provide insights into the molecular mechanisms of salt and water secretion by lung submucosal glands, and they suggest that while murine submucosal gland fluid secretion in response to cholinergic stimulation can originate from CFTR-expressing serous acinar cells, it is not dependent upon CFTR function.
