A beta-glucan synthase gene was isolated from the genomic DNA of polypore mushroom Sparassis crispa, which reportedly produces unusually high amount of soluble beta-1,3-glucan (beta-glucan). Sequencing and subsequent open reading frame analysis of the isolated gene revealed that the gene (5,502 bp) consisted of 10 exons separated by nine introns. The predicted mRNA encoded a beta-glucan synthase protein, consisting of 1,576 amino acid residues. Comparison of the predicted protein sequence with multiple fungal beta-glucan synthases estimated that the isolated gene contained a complete N-terminus but was lacking approximately 70 amino acid residues in the C-terminus. Fungal beta-glucan synthases are integral membrane proteins, containing the two catalytic and two transmembrane domains. The lacking C-terminal part of S. crispa beta-glucan synthase was estimated to include catalytically insignificant transmembrane alpha-helices and loops. Sequence analysis of 101 fungal beta-glucan synthases, obtained from public databases, revealed that the beta-glucan synthases with various fungal origins were categorized into corresponding fungal groups in the classification system. Interestingly, mushrooms belonging to the class Agaricomycetes were found to contain two distinct types (Type I and II) of beta-glucan synthases with the type-specific sequence signatures in the loop regions. S. crispa beta-glucan synthase in this study belonged to Type II family, meaning Type I beta-glucan synthase is expected to be discovered in S. crispa. The high productivity of soluble beta-glucan was not explained but detailed biochemical studies on the catalytic loop domain in the S. crispa beta-glucan synthase will provide better explanations.

Lymphangiomas result from a failure of lymphatic drainage into the venous system due to atresia or an insufficiency of the efferent lymphatic channels. The neck and axillary regions are most commonly affected, while the condition is rarely found in the inguinal area, scrotum, retroperitoneal space, abdominal viscera, arm, pelvis or bones. We report a case of a cystic lymphangioma of the lower abdomen, penis and scrotum in a 29-year-old man.

BACKGROUND: Medication adherence is important for hypertension management but still stay low level. It is reasonable method to classify medication nonadherence into intentional nonadherence and unintentional nonadherence and manage it according to this categories. This study aimed to explore medication adherence and its predictors in community patients with hypertension, especially dividing into intentional nonadherence and unintentional nonadherence. METHODS: Study subjects included 1,988 patients who were prescribed hypertension drugs among 2012 community health survey subjects of 10 cities in Gyeongsangnamdo and we analyzed medication adherence with hypertension and its predictors. We conducted chi-square test for nominal variable and ANOVA test for continuous variable and use multinominal regression to analyze independent predictors of intentional nonadherence and unintentional nonadherence in contrast to medication adherence. RESULTS: Of the 1,988 patients, 49.7% were adherent, 26.1% were unintentionally nonadherent and 24.2% intentionally nonadherent. Independent predictors of unintentional nonadherence were depressive symptoms (odds ratio [OR]=1.696, P=0.047) and arthritis (OR=1.319, P=0.030) and independent predictors of intentional nonadherence were cardiocerebrovascular disease (OR=1.464, P=0.044), self-efficacy (OR=0.984, P=0.007), beliefs about medications questionnaire (necessity [OR=0.834, P<0.001] and concern [OR=1.236, P<0.001]). CONCLUSIONS: In order to manage hypertension in community, improvement in medication adherence is needed. Depressive symptom and self-efficacy need to be managed, but especially patients'beliefs about their medication need to be considered to improve intentional nonadherence.

PURPOSE: inhaled nitric oxide(iNO) is an excellent method for the postoperative pulmonary hypertension in congenital heart disease. But more detailed care is needed because of the development of rebound pulmonary hypertension after NO Withdrawal. We performed this study in order to discontinue the iNO successfully by way of presenting the adequate weaning and supplying methods. METHODS: Between January, 1998 and August, 1999 we sudied 10 patients who had rebound pulmonary hypertension(RPH) after iNO withdrawal. We completed the iNO in these patween the first the second trial of the weaning process. We tried to discover the differences between the first and second weaning process. We measured NO concentration at the start and just before NO withdrawal and during the period of weaning process. Moreover, to identify the iNO effects during the weaning of the iNO, we counted the degree of the change of PaO2/FiO2and mean PAP/SAP beween initial and at half of the initial NO concentration. RESULTS: Second weaning had a longer duration weaning process(11+/-0 cersus 5+/- hours, P<0.05), lower NO concentration just before NO withdrawal(2+/-.6 versus 4+/-ppm, P<0.05). In the change of the mean PAP/SAP and PaO2/FiO2as iNO was weaning from the initial iNO concentration to a half of the initial iNO concentration, the degree of increase in mean PAP/SAP(0.026+/-.07 versus 0.054+/-.07, P<0.05) and the degree of decrease in PaO2/FiO2(49+/-4 versus 65+/-2, P<0.05) were smaller in the second in the second weaning process than the first weaning process. CONCLUSION: A successful weaning of iNO can be performed with a low iNO concentration at the start and just before withdrawal and with the long duration iNO weaning process. Moreover, We speculate that the degree of change in the mean PAP/SAP and PaO2/FiO2at the half of the iNO weaning process are an indicator for the development of RPH.

PURPOSE: To evaluate the radiologic features of fibrothecoma of the ovary, which is a rare solid tumor originating from the ovarian sex cord-stroma. MATERIALS AND METHODS: The radiologic findings of 29 patients with pathologically-proven fibrothecoma of the ovary were retrospectively evaluated for bilaterality, size, shape, margin, echogenecity, CT attenuation, signal intensity on magnetic resonance imaging, calcification, and amount of ascites. RESULTS: All fibrothecomas were unilateral, and had well defined margins. The diameter of the mass was 4-18(mean, 9.6)cms. Elghteen of 29 tumors were round or oval with a smooth margin, and eleven were lobulated. The internal architecture of the tumor was purely solid in 21 patients, predominantly solid in six, and pre-dominantly cystic in two. A broad spectrum of sonographic features was apparent, including a homogeneously hypoechoic mass (with posterior shadowing in four cases, and without posterior shadowing in ten), a homoge-neously hyperechoic mass in seven cases, an anechoic mass with septatations in two, and a mixed echoic mass in six. On precontrast CT scans, the mass was isodense to the uterine myometrium in eight of nine cases, while on postcontrast scans the lesion was slightly hypodense to the myometrium in seven cases and isodense in one. On T1-weighted MR images, nine of ten cases showed a relatively homogeneous low signal intensity, while on T2-weighted images, signal intensity was homogeneously low in two patients and predominantly low with focal high intensity in seven of the other eight. On gadolinium-enhanced T1-weighted images, most tu-mors showed slight heterogeneous enhancement. Calcifications were present in two cases, and in two others there was a large amount of ascites. CONCLUSION: The characteristic finding of ovarian fibrothecomas is a well-defined, oval or lobulated homoge-neously solid mass, which on CT scans enhances less than uterine myometrium and demonstrates a predomi-nantly low signal intensity on both T1- and T2-weighted images. However, a predominantly solid mass with cystic components or a predominantly cystic mass may also be presented.

Medial meniscal root tears have been repaired using various methods. Arthroscopic all-inside repair using a suture anchor is one of the popular methods. However, insertion of the suture anchor into the proper position at the posterior root of the medial meniscus is technically difficult. Some methods have been reported to facilitate suture anchor insertion through a high posteromedial portal, a posterior trans-septal portal, or a medial quadriceptal portal. Nevertheless, many surgeons still have difficulty during anchor insertion. We introduce a technical tip for easy suture anchor insertion using a 25° curved guide and a soft suture anchor through a routine posteromedial portal.

OBJECTIVE: This study assessed whether both physical disability and perceived dependence relate to depression or whether perceived dependence in personal care activities, household activities, community mobility and recreational activities is an intermediate step in the relationship between physical disability and depressive symptoms. METHODS: Data come from a cross-sectional survey of 209 women, aged 55 or older, with osteoarthritis (OA). Mediation analyses occurred in four step and included logistic regression analyses as outlined by Baron & Kenny. RESULTS: The results from step 1 showed that greater difficulty with each domain of physical disabilities was significantly related to greater perceived dependence. In step 2, greater perceived dependence was significantly associated with greater depressive symptoms in all domains. Step 3 analyses showed that greater physical disabilities in each domain were significantly associated with depression. The final step testing mediation indicated that personal care activities, household activities and community mobility were fully mediated by perceived dependence. That was, once dependence was taken into account, the relationship between physical disabilities and depression was no longer significant. Partial mediation was found for dependence and recreational activity limitations. CONCLUSION: It is important to take into account the experience of perceived dependence as a mediator in understanding the relationship between disability and depression in the domains of personal care, household, and community mobility. To conclude, these findings point to the importance of taking into account an individual's reaction to their disability rather than just focusing on the severity of disability.
