PURPOSE: Non-intraocular pressure (IOP) factors such as vascular factors have been identified as contributing to normal tension glaucoma. However, there is not an established range of haemorheological factors considered normal, nor are there standardized tests. In this study, we investigated differences in blood viscosity and haemorheological parameters between patients with normal tension glaucoma (NTG) and normal controls using a new instrument called the BVD-RO1 (BIO-VISCO. Inc., Jeonju, Korea). METHODS: Twenty patients with NTG and 20 age-matched normal controls were included in the study. Haemorheological parameters of the venous blood samples, including blood viscosity at the shear rates of 300 (high shear rate) and 1 (low shear rate) s-1 were measured using an automated scanning capillary tube viscometer. RESULTS: More hematocrit concentration was detected in the NTG group than in the control group (p < 0.05). Furthermore, higher blood viscosities at the high (p < 0.01) and low (p < 0.01) shear rates were found in the NTG group. CONCLUSIONS: The NTG patients differed in blood viscosity with the control group. This may signify the importance of hemodynamic factors in the pathogenesis of NTG.

In our present study, we investigated the effects of continentalic acid on Streptococcus mutans (S. mutans) biofilm. Methanol extract of Aralia continentalis (A. continentalis) was suspended in water and sequentially partitioned with CHCl3, ethyl acetate (EtOAc), and n-butanol (n-BuOH). The CHCl3 fraction showed the highest activity and an antibacterial compound against S. mutans was isolated from this preparation through various chromatography methods by bioassay guided fractionation. MS, 1H-NMR and 13C-NMR analysis showed that the active principle was continentalic acid which was confirmed to show significant inhibitory effects against S. mutans biofilm. These results may provide some scientific rationale for the traditional use these extracts for the treatment of dental diseases.

OBJECTIVES: We aimed to evaluate discrepancies between self-awareness of memory functions and actual memory functions in the elderly community. METHODS: A total of 369 individuals aged over 65 years from four elderly community centers completed clinical evaluation, neuropsychological batteries of the Korean version of the Consortium to Establish a Registry for Alzheimer's disease (CERAD-K), the Geriatric Depression Scale (GDS), the Instrumental Activities of Daily Living (IADL), and the Hachinski Ischemic Score. RESULTS: Among the elderly particpants, 26.3% showed incorrect awareness regarding their memory function. Those with subjective memory complaints included 73.5% with no memory impairment, while those without memory complaints included 11.3% of those with amnestic mild cognitive impairment (aMCI) and 4.3% of those with Alzheimer's disease (AD). Subjective memory complaints were significantly associated with depression. Among the elderly with no memory complaints, incorrect awareness was associated with 'no previous education' (OR 3.6, 95% CI 1.3-9.8), 'age over 80' (OR 2.4, 95% CI 1.1-5.4), and 'male' (OR 2.3, 95% CI 1.0-5.2) ; however, it was not significantly associated with depression. CONCLUSION: Incorrect awareness of memory impairment is prevalent among the elderly. Further, elderly individuals of an advanced age with no education may have memory impairment without memory complaints.

The typical presentation of intussusception includes intermittent severe abdominal pain, vomiting, rectal bleeding, and the presence of an abdominal mass. We present a case of intussusception after abdominal blunt trauma along with a literature review. A 4-year-old girl was admitted to the emergency department after a bicycle accident. She complained of progressively worsening abdominal pain, but there was no vomiting, fever, bloody stool, or abdominal mass. She was finally diagnosed with traumatic intussusception by ultrasonography and treated with air reduction. Because the typical symptoms are unusual in traumatic intussusception, close attention must be paid to avoid a delayed diagnosis.

Imperforated hymen, vaginal atresia or high transverse vaginal septum are caused by incomplete vaginal canalization. The infant may be present with distention of the vagina and the uterus with glandular secretions stimulated by maternal estrogens, known as hydrometrocolpos. We report two cases of hydrometrocolpos. In the first case, distal vaginal atresia with cystovaginal fistula was revealed by a contrast fluoroscope through the percutaneous catheterization. In the second case, urogenital sinus was detected by a fistulogram through a single orifice in the genital area. We decompressed the cystic mass by ultrasonogram guided aspiration, promptly at birth, then achieved the transient drainage of cystic fluids by percutaneous catheterization.

In our previous study, we found that spermine and putrescine inhibited spontaneous and acetylcholine (ACh)-induced contractions of guinea-pig stomach via inhibition of L-type voltage- dependent calcium current (VDCCL). In this study, we also studied the effect of spermidine on mechanical contractions and calcium channel current (IBa), and then compared its effects to those by spermine and putrescine. Spermidine inhibited spontaneous contraction of the gastric smooth muscle in a concentration-dependent manner (IC50=1.1+/-0.11 mM). Relationship between inhibition of contraction and calcium current by spermidine was studied using 50 mM high K+-induced contraction: Spermidine (5 mM) significantly reduced high K+(50 mM)-induced contraction to 37+/-4.7% of the control (p<0.05), and inhibitory effect of spermidine on IBa was also observed at a wide range of test potential in current/voltage (I/V) relationship. Pre- and post-application of spermidine (5 mM) also significantly inhibited carbachol (CCh) and ACh-induced initial and phasic contractions. Finally, caffeine (10 mM)-induced contraction which is activated by Ca2+-induced Ca2+release (CICR),` was also inhibited by pretreatment of spermidine (5 mM). These findings suggest that spermidine inhibits spontaneous and CCh-induced contraction via inhibition of VDCCL and Ca2+releasing mechanism in guinea-pig stomach.

BACKGROUND/AIMS: Recently, many cases of vitamin K-dependent coagulopathy of unknown origin have been reported. Such patients lack any relevant family history and have no systemic disease, raising suspicion of superwarfarin intoxication. We evaluated individual risk factors causing coagulopathy and hemorrhagic symptoms in patients with suspected superwarfarin intoxication. In addition, we determined how to effectively treat vitamin K-dependent coagulopathy caused by suspected superwarfarin intoxication. METHODS: Seven patients with suspected superwarfarin intoxication who lacked any definitive history of rodenticide ingestion were included. Thirty-one patients initially diagnosed with rodenticide poisoning were also included. We performed a retrospective chart review of all subjects and examined clinical data including patient demographics and medical histories. RESULTS: Patients initially diagnosed with rodenticide poisoning were divided into two groups, one of which had a laboratory abnormality (prothrombin time [PT] > 13 seconds) and another group with PTs in the normal range. There was no significant difference between the two groups in any of age, gender, the extent of chronic alcohol consumption, the causative rodenticide, psychiatric problems, ingestion of drugs interacting with warfarin, the extent of intoxication, or the type of ingestion attempt. The albumin level of the former group was significantly lower than that of the latter group (p = 0.014). Furthermore, a significant difference between the two groups was evident in terms of simultaneous ingestion of rodenticide and alcohol (p = 0.023). CONCLUSIONS: Most patients with superwarfarin poisoning did not exhibit any complication. When such complications were evident, they were associated with serum albumin level and coingestion of rodenticide and alcohol.

BACKGROUND/AIMS: For many years, conventional treatment for multiple myeloma (MM) not ineligible for high-dose therapy has been the combination of oral melphalan and prednisone (MP). However, melphalan-based regimens are associated with numerous complications. Another alkylating agent, cyclophosphamide, has similar effects on MM and is associated with fewer reports of complications. Therefore, cyclophosphamide-based regimens have usually been used as salvage therapy in patients with refractory or relapsed MM, despite the development of newer drugs. The purpose of this report was to evaluate the efficacy and tolerability of cyclophosphamide and prednisone as a first-line therapy for MM. METHODS: For the period January 2002 to June 2012, we retrospectively analyzed 29 patients newly diagnosed with MM who underwent a treatment regimen consisting of intravenous cyclophosphamide (1,000 mg/kg) for 1 day and prednisone (100 mg) for 4 days. RESULTS: The rate of response to this regimen was 31.1 percent. The median progression-free survival (PFS) was 5.5 months and the median overall survival (OS) was 47.3 months. The regimen was well tolerated. Adverse effects of grades above III were as follows: anemia in seven patients (24.1%), neutropenia in five patients (17.2%), and thrombocytopenia in two patients (6.8%). These adverse effects were easily adjusted. No one developed a secondary malignancy or hemorrhagic cystitis. CONCLUSIONS: Although PFS was less than for the MP regimen, median OS was better than for the MP regimen. Furthermore, the cyclophosphamide-prednisone regimen was well tolerated, and the adverse effects that did occur were easily adjusted. The cyclophosphamide-prednisone combination regimen may represent an effective and well tolerated first-line therapy for non-transplant candidates with MM.

PURPOSE: Our previous study demonstrated the hypoglycemic effects of mulberry (Morus alba L.) leaf and the underlying mechanisms. Here we explored the potency of mulberry twigs (TW) and root barks (RB) in postprandial hypoglycemic effects in vitro and in vivo. METHODS: The major components of TW and RB were determined by high performance liquid chromatography (HPLC). Alpha-glucosidase inhibition and glucose/fructose uptake inhibition in Caco-2 cells were determined for TW, RB, and their major components, followed by an oral sugar tolerance test (OSTT) in streptozotocin-induced diabetic rats. Male Wistar rats were fed a high-fat diet for 2 weeks and then a single dose of streptozotocin (35 mg/kg B.W) was administered by intraperitoneal injection. Rats with fasting blood glucose levels above 126 mg/dL were randomly divided into 5 groups (n = 8/group) for the following treatments by gavage for 4 weeks: vehicle (normal control and diabetic control), 200 mg/kg B.W of TW or RB or 100 mg/kg B.W of oxyresveratrol (OXY). RESULTS: OXY and mulberroside A were identified as the major components of TW and OXY, mongolicin, and kuwanon H for RB. A significant inhibitory activity on alpha-glucosidase was found for TW, RB, and OXY (p = 0.0099). There was a dose-dependent inhibition of TW and RB on the intestinal sugar uptakes in Caco-2 cells, showing a greater impact on fructose compared to glucose. The OSTT showed that TW and RB significantly delayed time to maximal concentration (p = 0.0088) and decreased maximal concentration (p = 0.0043) compared to the control group. CONCLUSION: These results suggest that TW and RB may have a postprandial hypoglycemic effect, particularly in the case of high fructose or sucrose intake. OXY was suggested as a contributor to the hypoglycemic effect of TW and RB. Further studies are needed for the systemic effect of TW and RB in circulation.
