The expression of nitric oxide synthase (NOS) isoforms in the ovaries of pigs was examined to study the involvement of nitric oxide, a product of NOS activity, in the function of the ovary. Western blot analysis detected three types of NOS in the ovary, including constitutive neuronal NOS (nNOS), endothelial NOS (eNOS) and inducible NOS (iNOS); eNOS immunoreactivity was more intense compared with that of iNOS or nNOS. Immunohistochemical studies demonstrated the presence of nNOS and eNOS in the surface epithelium, stroma, oocytes, thecal cells, and endothelial cells of blood vessels. Positive immunoreactions for nNOS and iNOS were detected in the granulosa cells from multilaminar and antral follicles, but not in those of unilaminar follicles. iNOS was detected in the surface epithelium, oocytes, and theca of multilaminar and antral follicles. Taking all of the findings into consideration, the observed differential expression of the three NOS isoforms in the ovary suggests a role for nitric oxide in modulating reproduction in pigs.

Melatonin (N-acetyl-5-methoxytryptamine), a pineal neurohormone, is a hydroxyl radical scavenger and antioxidant, and plays an important role in the immune system. We studied the effect of exogenous melatonin on the pathogenesis of experimental autoimmune encephalomyelitis (EAE). EAE was induced in Lewis rats by immunization with rat spinal cord homogenates. Subsequent oral administration of melatonin at 5 mg/kg significantly reduced the clinical severity of EAE paralysis compared with administration of the vehicle alone (p<0.01). Infiltration of ED1 macrophages and CD4 T cells into spinal cords occurred both in the absence and presence of melatonin treatment, but melatonin-treated rats had less spinal cord infiltration of inflammatory cells than did the control group. ICAM-1 immunoreactivity in the blood vessels of EAE lesions was decreased in melatonin-treated rats compared to vehicle-treated rats. These findings suggest that exogenous melatonin ameliorates EAE via a mechanism involving reduced expression of ICAM-1 and lymphocyte function associated antigen-1a in autoimmune target organs.

Objective: Studies on gait and autonomic dysfunction have been insufficient so far, particularly de novo Parkinson’s disease (PD). The aim of this study was to identify the association between gait dynamics and autonomic dysfunction in patients with de novo PD. Methods: A total 38 patients with de novo PD were retrospectively included in this study. Details of patients’ dysautonomia were assessed using the Scales for Outcomes in Parkinson’s Disease-Autonomic Dysfunction (SCOPA-AUT). For assessment of gait, a computerized gait analysis was performed using the GAITRite system for forward gait and backward gait. High SCOPA-AUT score (PD-HSAS) group and low SCOPA-AUT score (PD-LSAS) group were identified according to their SCOPA-AUT scores. Results: Nineteen (50%) patients with high SCOPA-AUT scores above median value (12.5) were assigned into the PD-HSAS group and others were assigned to the PD-LSAS group. Compared with the PD-LSAS group, the PD-HSAS group exhibited slower gait, shorter stride, decreased cadence, increased double support phase, decreased swing phase, and increased variability in swing time. Total SCOPA-AUT score showed significantly positive correlations with gait variability and instability but a negative correlation with gait hypokinesia. In subdomain analysis, urinary dysautonomia was highly associated with impairment of gait dynamics. All significant results were found to be more remarkable in backward gait than in forward gait. Conclusion Our findings suggest that alteration in gait dynamics, especially backward gait, is highly associated with autonomic dysfunction in patients with de novo PD.

Uterine leiomyomas are the most common benign uterine tumors. They are estimated to be present in at least 20% of all women of reproductive age and may be asymptomatic in 40-50% of women older than 40 years of age. They may be subserosal, intramural, or submucosal in location within the uterus or located in the cervix, in the broad ligament, or on a pedicle. But it seems to be rare to experience a intraligamentary huge leiomyoma in the broad ligament.Recently we have experienced a case of intraligamentary huge leiomyoma with its weight of 3146 gm in 45 year-old primiparous woman. We present this case with a brief review of the literature.

The vast majority of malignant tumors involving the vagina are secondary spread from primary malignant lesion of the cervix uteri, the sigmoid colon, the bladder and the vulva. Primary invasive carcinoma of the vagina remains among the rare gynecologic malignant tumor. The diagnosis of primary carcinoma of the vagina requires that the cervix and the vulva be intact and no clinical evidence of other primary tumors exist. Greater than 80-90% of all vaginal tumors are squamous cell type. We experienced two cases of primary vaginal cancer of 68 years old woman without any other gynecologic disease and 67 years old woman after hysterectomy for benign desease. We presented these cases with a brief review of related literatures.

To examine the involvement of phospholipase D (PLD)isozymes in postnatal testis development, the expression ofPLD1 and PLD2 was examined in the mouse testis atpostnatal weeks 1, 2, 4, and 8 using Western blot analysisand immunohistochemistry. The expression of both PLD1and PLD2 increased gradually with development frompostnatal week 1 to 8. Immunohistochemically, PLDimmunoreactivity was detected in some germ cells in thetestis and interstitial Leydig cells at postnatal week 1.PLD was mainly detected in the spermatocytes andresidual bodies of spermatids in the testis after 8 weeksafter birth. The intense immunostaining of PLD in Leydigcells remained unchanged by postnatal week 8. Thesefindings suggest that PLD isozymes are involved in thespermatogenesis of the mouse testis.

Brucellosis is a zoonotic infection that is usually transmitted from cattle to humans through ingestion of animal milk, direct contact with animal parts, or inhalation of aerosolized particles. In Korea, brucellosis seem to be transmitted through close contact with blood, fetus, urine, and placenta of domestic cow that has been infected by Brucella abortus, or inhalation of B. arbortus while examining or slaughtering cow. Brucella melitensis infection is rare in Korea and there have been no reported cases of B. melitensis originating from other countries until now. This report details a case of complicated brucellosis with infective spondylitis in a 48-year-old male construction worker recently returned from Iraq. Infection with B. melitensis was confirmed using 16s rRNA sequencing and omp31 gene analysis. The patient was successfully treated using a combination of rifampin, doxycycline, and streptomycin, in accordance with WHO guidelines. This is the first reported case of complicated brucellosis with infective spondylitis in Korea caused by B. melitensis originating from Iraq.

PURPOSE: Severe sepsis is associated with functional disability among patients surviving an acute phase of infection. Efforts to improve functional impairment are important. We assessed the effects of early exercise rehabilitation on functional outcomes in patients with severe sepsis. MATERIALS AND METHODS: A prospective, single-center, case-control study was conducted between January 2013 and May 2014 at a tertiary care center in Korea. Patients with severe sepsis and septic shock were enrolled and randomized to receive standard sepsis treatment or intervention. Intervention involved early targeted physical rehabilitation with sepsis treatment during hospitalization. Participants were assessed at enrollment, hospital discharge, and 6 months after enrollment. Functional recovery was measured using the Modified Barthel Index (MBI), Functional Independence Measure (FIM), and Instrumental Activities of Daily Living (IADL). RESULTS: Forty participants (21 intervention patients) were included in an intention-to-treat analysis. There were no significant differences in baseline MBI, FIM, and IADL between groups. Intervention yielded greater improvement of MBI, FIM, and IADL in the intervention group at hospital discharge, but not significantly. Subgroup analysis of patients with APACHE II scores ≥10 showed significantly greater improvement of physical function at hospital discharge (MBI and FIM) in the intervention group, compared to the control group (55.13 vs. 31.75, p=0.048; 52.40 vs. 31.25, p=0.045). Intervention was significantly associated with improvement of MBI in multiple linear regression analysis (standardized coefficient 0.358, p=0.048). CONCLUSION: Early physical rehabilitation may improve functional recovery at hospital discharge, especially in patients with high initial severity scores.
