Pulmonary edema is a major cause of mortality due to acute lung injury (ALI). The involvement of protein kinase C-delta (PKC-delta) in ALI has been a controversial topic. Here we investigated PKC-delta function in ALI using PKC-delta knockout (KO) mice and PKC inhibitors. Our results indicated that although the ability to produce proinflammatory mediators in response to LPS injury in PKC-delta KO mice was similar to that of control mice, they showed enhanced recruitment of neutrophils to the lung and more severe pulmonary edema. PKC-delta inhibition promoted barrier dysfunction in an endothelial cell layer in vitro, and administration of a PKC-delta-specific inhibitor significantly increased steady state vascular permeability. A neutrophil transmigration assay indicated that the PKC-delta inhibition increased neutrophil transmigration through an endothelial monolayer. This suggests that PKC-delta inhibition induces structural changes in endothelial cells, allowing extravasation of proteins and neutrophils.

A large cell neuroendocrine carcinoma of the stomach is extremely rare. We have reviewed the medical records and imaging studies of the four patients that presented with a large cell neuroendocrine carcinomas of the stomach. On a barium study and CT imaging, a gastric large cell neuroendocrine carcinoma is depicted as an ulcerofungating tumor with minimal peritumoral infiltration and metastatic lymphadenopathy in the perigastric area. These findings are similar to findings for advanced gastric cancer, especially Borrmann type II. However, a gastric large cell neuroendocrine carcinoma is highly malignant with a significantly worse prognosis than a usual adenocarcinoma.

BACKGROUND: Although nutritional problems associated with dialysis are well described, nutritional problems after renal transplantation have received little attention. Nutrition interventions play an important role in prevention and management of common health problems associated with renal transplantation such as obesity, hypertension, diabetes, and cardiovascular disease. METHODS: Sixty-four kidney transplant recipients who received post-transplant management at our hospital replied to the questionnaire. The questionnaire included 102 questions on the amount and types of Korean foods that they consumed last week. Nutritional elements of diet in renal transplant patients who consume Korean food were analyzed on the basis of the survey. RESULTS: The mean energy and protein of daily intake were 2,088+/-1,016 kcal and 75.5+/-38.2 g. Patients' diets were generally sufficient, but characterized by deficiencies in vitamin B2, vitamin D, niacin, calcium, and magnesium intake. CONCLUSIONS: Dietary advice is required with regard to intake of some nutritional elements for kidney transplant recipients who consume Korean foods. Their main nutritional problem is obesity after transplantation. Attention should be paid to prevention of nutritional imbalance.

The objective of this study was to assess the effect of lidocaine jelly application to chest tubes on the intensity and duration of overall pain, chest tube site pain and the required analgesics for postoperative pain relief in coronary artery bypass graft (CABG) patients. For patients in group L, we applied sterile 2% lidocaine jelly on the chest tubes just before insertion, and for patients in group C, we applied normal saline. Overall visual analogue scale (VAS), maximal pain area with their VAS were documented postoperatively, and the frequency that button of patient-controlled analgesia was pressed (FPB) and total fentanyl consumption were assessed. The number of patients who complained that tube site was the most painful site was significantly higher in group C than in group L (85% vs. 30% at extubation, P<0.001). The overall VAS score was significantly higher in group C than in group L (39.14+/-12.49 vs. 27.74+/-13.76 at extubation, P=0.006). After all of the tubes were removed, the VAS score decreased more in group C (5.74+/-4.77, P<0.001) than in group L (3.05+/-2.48, P<0.001). FPB and total fentanyl consumption were significantly higher in group C than in group L (73.00, 59.00-78.00 vs. 34.00, 31.00-39.25, P<0.001; 2,214.65+/-37.01 vs. 1,720.19+/-361.63, P<0.001, respectively). Lidocaine jelly application is a very simple way to reduce postoperative pain by reducing chest tube site pain after CABG. (Clinical Trials Registry No. ACTRN 12611001215910)

Distinguishing individual Russula species has been difficult due to extensive phenotypic plasticity and obscure morphological and anatomical discontinuities. Due to highly similar macroscopic features, such as the presence of a red-cap, species identification within the Russula subgenus Amoenula is particularly difficult. Three species of the subgenus Amoneula have been reported in Korea. We used a combination of morphology and three molecular markers, the internal transcribed spacer (ITS), 28S nuclear ribosomal large subunit (LSU), and RNA polymerase II gene (RPB2), for identification and study of the genetic diversity of Russula subgenus Amoenula in Korea. We identified only two species in Korea (R. mariae and R. violeipes); these two species were indistinguishable according to morphology and LSU, but were found to be reciprocally monophyletic species using ITS and RPB2. The markers, ITS, LSU, and RPB2, have been tested in the past for use as DNA barcoding markers, and findings of our study suggest that ITS and RPB2 had the best performance for the Russula subgenus Amoneula.

The fungal genus Suillus Micheli ex S. F. Gray plays important roles in the survival and growth of plant seedlings. Humans have utilized these ectomycorrhizal fungi to enhance the nutrient uptake and defense systems of plants, particularly in the reforestation of coniferous forests. The genus Suillus is easily distinguishable by its distinctive morphological features, although the morphology of the fruiting body does not facilitate reliable interspecies discrimination. On the basis of micro-morphological features and internal transcribed spacer sequence analysis, we found that 51 of 117 Korean Suillus specimens had initially been misidentified. The list of the 12 Suillus species previously recorded in Korea was re-evaluated and revised to only eight distinct species: S. americanus, S. bovinus, S. granulatus, S. grevillei, S. luteus, S. pictus, S. placidus, and S. viscidus. We provide taxonomical descriptions for six of these species from the sample specimens.

Human reflexes are simple motor responses that are automatically elicited by various sensory inputs. These reflexes can provide valuable insights into the functioning of the nervous system, particularly the brainstem and spinal cord. Reflexes involving the brainstem, such as the blink reflex, laryngeal adductor reflex, trigeminal hypoglossal reflex, and masseter H reflex, offer immediate information about the cranial-nerve functionality and the overall state of the brainstem. Similarly, spinal reflexes such as the H reflex of the soleus muscle, posterior root muscle reflexes, and sacral reflexes provide crucial information about the functionality of the spinal cord and peripheral nerves. One of the critical benefits of reflex monitoring is that it can provide continuous feedback without disrupting the surgical process due to no movement being induced in the surgical field. These reflexes can be monitored in real time during surgical procedures to assess the integrity of the nervous system and detect potential neurological damage.It is particularly noteworthy that the reflexes provide motor and sensory information on the functional integrity of nerve fibers and nuclei. This article describes the current techniques used for monitoring various human reflexes and their clinical significance in surgery. We also address important methodological considerations and their impact on surgical safety and patient outcomes. Utilizing these methodologies has the potential to advance or even revolutionize the field of intraoperative continuous monitoring, ultimately leading to improved surgical outcomes and enhanced patient care.

Primary lymphoma of the urinary bladder is a rare non-epithelial bladder tumor accounting for less than 1% of all bladder tumors. Approximately 17 cases of MALT lymphomas of bladder have been reported in the literature. Most reported MALT lymphomas of bladder have a female sexual preponderance with a mean age of 58 years with common presenting symptoms of hematuria, dysuria and urinary frequency. The reported prognosis of MALT lymphoma of the urinary bladder is excellent. We report a case of MALT lymphoma of urinary bladder in a 57-year-old woman patient who presented with a two-year history of persistent dysuria and urinary frequency. An intravenous pyelogram and cystoscopy revealed a 1 cm focal elevated lesion at the base of urinary bladder. The tissue obtained by transurethral resection (TUR) showed plasma cell infiltration consistent with low grade marginal zone B cell lymphoma. The immunohistochemical studies showed an immunoglobulin restriction to lambda light chain while the nested polymerase chain reaction analysis of the tissue showed a monoclonal Ig heavy-chain gene rearrangement. The clinical staging protocol revealed that the tumor was primarily arising from the urinary bladder with no evidence of other site involvements. The patient received radiation therapy of 3060 cGy in 17 fractions.

BACKGROUND/AIMS: Although controversial, probiotics and dietary fiber are commonly used for patients with irritable bowel syndrome (IBS). We evaluated the effects of multistrain probiotics on the symptoms of IBS to determine whether the addition of dietary fi ber had an additive effect on constipation-predominant IBS. METHODS: A total of 142 participants who met the Rome III criteria were recruited and randomized into a control group or a test group. Participants in the control group received multistrain probiotic fermented milk with Streptococcus thermophilus, Lactobacillus acidophilus and Bifidobacterium infantis; the participants in the test group received the same probiotic fermented milk mixed with dietary fi ber such as sea tangle extracts, radish extracts and glasswort extracts. The patients were treated for four weeks. RESULTS: Most of the symptoms of IBS, with the exception of fl atulence, stool consistency, and frequency of defecation, signifi cantly improved in both groups. In the analysis of IBS subtypes, especially constipation-predominant IBS, the frequency and duration of defecation and straining at stool were improved more in the test group than in the control group. CONCLUSIONS: Dietary fiber had additive benefits for the symptoms of constipation, especially in constipation-predominant IBS.

OBJECTIVE: Wine has been the focus in the prevention of epithelial ovarian cancer (EOC) development because resveratrol abundant in wine has anti-carcinogenic properties. However, epidemiologic results have been heterogenous in the chemopreventive effect of wine on the development of EOC. Thus, we performed a meta-analysis for comparing EOC risk between wine and never drinkers using previous related studies. METHODS: After extensive search of the literature between January 1986 and December 2008, we analyzed 10 studies (3 cohort and 7 case control studies) with 135,871 women, who included 65,578 of wine and 70,293 of never drinkers. RESULTS: In all studies, there was no significant difference in EOC risk between wine and never drinkers (odds ratio [OR], 1.13; 95% confidence interval [CI], 0.92 to 1.38; random effects). When we performed re-analysis according to the study design, 3 cohort and 7 case control studies showed that there were also no significant differences in EOC risk between wine and never drinkers, respectively (OR, 1.44 and 1.04; 95% CI, 0.74 and 2.82 and 0.88 to 1.22; random effects). In sub-analyses using 2 case-control studies, EOC risk was not different between former and never drinkers (OR, 1.12; 95% CI, 0.87 to 1.44; fixed effect), and between current and former drinkers (OR, 0.74; 95% CI, 0.41 to 1.34; random effects). CONCLUSION: Although resveratrol, abundantly found in wine, is a promising naturally occurring compound with chemopreventive properties on EOC in preclinical studies, this meta-analysis suggests the epidemiologic evidence shows no association between wine drinking and EOC risk.
