RESUMEN

The purpose of this study was to develop a brief rating scale of post-traumatic stress disorder (PTSD) symptoms among sexual violence victims. We analyzed the data from 195 victims and 220 non-victims to select meaningful items from the original PTSD rating scales. We also examined the validity of the brief scale by assessing internal consistency and ROC curves. The optimal cutoff scores for each brief scales were obtained. The results showed that a different approach may be required for early intervention in different age groups.

RESUMEN

The goal of this study was to evaluate the association between gallbladder (GB) polyps and metabolic syndrome. A total of 5,685 healthy subjects were included, and 485 of these subjects had GB polyps and 744 had metabolic syndrome. In this study, metabolic syndrome was diagnosed according to standards suggested by the AHA/NHLBI ATP III 2005, and abdominal obesity (> or = 90 cm in men and > or = 85 cm in women for Korean) was diagnosed according to standards set forth by the Korean Society for Study of Obesity. Biphasic logistic regression adjusted for age and gender was used to evaluate the association between metabolic syndrome and GB polyps. Subjects who were male (OR, 1.493; 95% CI, 1.11-2.00) and hepatitis B suface Ag (HBsAg) positive (OR, 1.591; 95% CI, 1.06-2.38) were significantly more likely to have GB polyps. The metabolic syndrome group had a higher risk of GB polyps (OR, 1.315; 95% CI, 1.01-1.69) than the group without metabolic syndrome. In conclusion, subjects who were HBsAg positive and male appear to be associated with the risk of GB polyps. The presence of metabolic syndrome also appears to be associated with the risk of GB polyps in Koreans.

RESUMEN

Sjogren's syndrome is an autoimmune disease that presents mainly as dry eyes and mouth, and occasionally with extra-glandular symptoms. A peripheral neuropathy is present in 10~30% of the cases with extra-glandular symptoms, although a tonic pupil caused by destruction of the ciliary ganglion is rare. We report a case of rheumatoid arthritis with Sjogren's syndrome presenting as a tonic pupil. A 29-year-old woman was admitted for evaluation of polyarthralgia and a tonic pupil. On physical examination, she had polyarthritis involving the jaws, shoulders, wrists, and hands. Her pupils were anisocoric and did not react to light, but constricted promptly to pilocarpine. Biopsy of the minor salivary gland showed lymphocyte infiltration. Rose-Bengal stain was positive. She was diagnosed with rheumatoid arthritis with Sjogren's syndrome and treated with prednisolone and hydroxychloroquine. Three months later, her polyarthritis had improved markedly, but she still had a tonic pupil.

RESUMEN

In adipocytes, insulin stimulates glucose transport primarily by promoting the translocation of GLUT4 to the plasma membrane. Requirements for Ca2+/ calmodulin during insulin-stimulated GLUT4 translocation have been demonstrated; however, the mechanism of action of Ca2+ in this process is unknown. Recently, myosin II, whose function in non-muscle cells is primarily regulated by phosphorylation of its regulatory light chain by the Ca2+/calmodulin-dependent myosin light chain kinase (MLCK), was implicated in insulin-stimulated GLUT4 translocation. The present studies in 3T3- F442A adipocytes demonstrate the novel finding that insulin significantly increases phosphorylation of the myosin II RLC in a Ca2+-dependent manner. In addition, ML-7, a selective inhibitor of MLCK, as well as inhibitors of myosin II, such as blebbistatin and 2,3-butanedione monoxime, block insulin- stimulated GLUT4 translocation and subsequent glucose transport. Our studies suggest that MLCK may be a regulatory target of Ca2+/calmodulin and may play an important role in insulin-stimulated glucose transport in adipocytes.

RESUMEN

We investigated the role of Ca2+ and protein kinases/phosphatases in the stimulatory effect of insulin on glucose transport. In isolated rat adipocytes, the simple omission of CaCl2 from the incubation medium significantly reduced, but did not abolish, insulin-stimulated 2-deoxy glucose (2-DG) uptake. Pre-loading adipocytes with intracellular Ca2+ chelator, 5,5'-dimethyl bis (o-aminophenoxy)ethane-N,N,N'N' tetraacetic acetoxymethyl ester (5,5'-dimethyl BAPTA/AM) completely blocked the stimulation. Insulin raised intracellular Ca2+ concentration ((Ca2+)i) about 1.7 times the basal level of 72+/-5 nM, and 5,5'-dimethyl BAPTA/AM kept it constant at the basal level. This correlation between insulin-induced increases in 2-DG uptake and (Ca2+)i indicates that the elevation of (Ca2+)i may be prerequisite for the stimulation of glucose transport. Studies with inhibitors (ML-9, KN-62, cyclosporin A) of Ca2+-calmodulin dependent protein kinases/phosphatases also indicate an involvement of intracellular Ca2+. Additional studies with okadaic acid and calyculin A, protein phosphatase-1 (PP-1) and 2A (PP-2A) inhibitors, indicate an involvement of PP-1 in insulin action on 2-DG uptake. These results indicate an involvement of Ca2+-dependent signaling pathway in insulin action on glucose transport.
