This study evaluated the quality characteristics of jelly prepared with different levels (0%, 5%, 10%, 15%, 20%, and 25%) of wild carrot (WC, Daucus carota L.) juice as a care food for the elderly. The lightness, redness, yellowness, and delta (Δ) values of the jelly (Control, WCJ5, WCJ10, WCJ15, WCJ20, and WCJ25) decreased with increasing amounts of wild carrot juice added. The mechanical properties, such as hardness, springiness, chewiness, and gumminess, of the jelly were decreased with increasing amounts of wild carrot juice added. The total polyphenol and total flavonoid contents of the jelly increased with increasing amounts of wild carrot juice added. The DPPH radical scavenging activity (IC50) also increased with increasing amounts of wild carrot juice added. The α-glucosidase inhibitory effects of wild carrot (WC) and WCJ25 were 71% and 54.4%, respectively, compared to the positive control (acarbose). The lipase inhibitory effects of WC and WCJ25 were 44.2% and 14.4%, respectively, compared to the positive control group (orlistat). On the other hand, the sensory evaluation score was the best at WCJ20, which contained 20% wild carrot juice. In conclusion, WCJ20 or WCJ25 is expected to be a care food for the elderly with respect to texture as well as the antioxidant and enzymatic activity (α-glucosidase inhibitory and lipase inhibitory activities).

OBJECTIVE: To compare the apparent diffusion coefficient (ADC) value using single-shot echo-planar imaging sequences at 3T and 1.5T for differentiation of benign fracture edema and tumor infiltration of the vertebral body. MATERIALS AND METHODS: A total of 46 spinal examinations were included in the 1.5T MRI group, and a total of 40 spinal examinations were included in the 3T MRI group. The ADC values of the lesion were measured and calculated. The diagnostic performance of the conventional MR image containing sagittal T2-weighted fat saturated image and each diffusion weighted image (DWI) with an ADC value with different b values were evaluated. RESULTS: The mean ADC value of the benign lesions was higher than that of the malignant lesions on 1.5T and 3T (p < 0.05). The sensitivity of the diagnostic performance was higher with an additional DWI in both 1.5T and 3T, but the sensitivities were similar with the addition of b values of 400 and 1000. The specificities of the diagnostic performances did not show significant differences (p value > 0.05). The diagnostic accuracies were higher when either of the DWIs (b values of 400 and 1000) was added to routine MR image for 1.5T and 3T. Statistical differences between 1.5T and 3T or between b values of 400 and 1000 were not seen. CONCLUSION: The ADC values of the benign lesions were significantly higher than those of the malignant lesions on 1.5T and 3T. There was no statistically significant difference in the diagnostic performances when either of the DWIs (b values of 400 and 1000) was added to the routine MR image for 1.5T and 3T.

OBJECTIVE: We described the technique of ultrasound (US)-guided percutaneous removal of the foreign bodies (FB) with hydro-dissection in the radiologic department and presented video files of several cases. MATERIALS AND METHODS: Four patients referred to the radiology department for US evaluation and US-guided percutaneous removal of the FBs in the upper and lower extremities between November, 2006 and November, 2013 were included in this study. The procedures started with US evaluation for the exact location and shape of the FB. A 5 mm-sized skin incision was made at the site of the nearest point from the FB where no passing arteries or tendons were present. We adopted a hydrodissection technique to separate the FB from adjacent tissue using a 2% lidocaine solution. Injected anesthetics detached the FBs from surrounding tissue and thereby facilitated removal. After the tip of the mosquito forceps reached the FB, the wooden FBs were removed. RESULTS: The mean time required for the entire procedure was approximately 20 minutes. There were no significant complications during the US-guided removal or long-term complications after the procedure. All 4 FBs were successfully removed from the soft tissue under US guidance. CONCLUSION: Ultrasound-guided percutaneous removal of the FBs with hydro-dissection in the radiology department is a less invasive and safe method over surgical removal in the operating room. Additionally, the use of a guide wire and serial dilator may help minimize soft tissue injury and facilitate the introduction of forceps.

OBJECTIVE: To evaluate the feasibility and clinical and angiographic outcomes of stent-assisted embolization for complex middle cerebral artery (MCA) aneurysms. METHODS: The records of 23 consecutive patients with 24 MCA aneurysms, who underwent stent-assisted embolization of the aneurysm, were retrospectively evaluated. RESULTS: Fifteen aneurysms were treated with one stent and 8 were treated using more than two stents (5 a stent-within-a-stent, 1 triple stents, and two Y-stent). Angiographically, complete or near complete occlusion was achieved in 15 aneurysms (65.2%), residual neck in five (21.7%), and residual aneurysm in three (13.1%). Five aneurysms demonstrated thrombosis within the stent during the procedure and hospitalization, and were resolved by intraarterial and intravenous Tirofiban injection. Symptomatic thromboembolic complications were developed in five patients and permanent deficits demonstrated in two patients with modified Rankin Scale 1 and 2, respectively. Treatment-related permanent morbidity and mortality rates were 8.3% and 0% with relatively high complication rate. Angiographic follow-up was available in 17 aneurysms at 6-31 months (mean, 13.2 months) and showed stable or improved in 15 (88.2%) and major and minor recurrence in one, respectively. CONCLUSION: Complex MCA aneurysms could be treated by stent-assisted coiling and showed lower recanalization rate during mid-term follow-up by effective flow diversion due to various stent-assisted techniques. Our results warrant further study with a longer follow-up period in a larger sample.

This study investigated the actual status of constipation. In total, 978 female students in Korea participated. We identified the relationship among constipation and life style, clothing patterns, housing patterns, dietary habits, and dietary intake in a constipation symptom group and a normal group. The actual constipation rate based on the Rome II criteria was 27.0% (n = 264). Body weight (p < 0.05) and body mass index (p < 0.05) in the constipation group were significantly higher than those in the normal group. The incidence of functional bowel disease and irritable bowel syndrome in the constipation group were significantly higher than those in the normal group. The discomfort of wearing underwear was significantly higher in the constipation group than that in the normal group. The constipation group revealed a significantly higher rate of irregular dietary habits than those in the normal group. The dietary diversity score of the normal group was 4.22 (p < 0.05), which was significantly higher than that of constipation group (4.12). No significant difference in life style factors was observed. It is necessary for university female students to correct their dietary habits, maintain food intake of three times per day, and select diverse foods. Furthermore, it is necessary for university female students to wear comfortable clothing to lessen symptoms and improve constipation rates.

BACKGROUND: The aim of the present study was to prepare hydroxyapatite (HA) and then characterize its effect on bone integration in a rabbit tibial defect model. The bone formation with different designs of HA was compared and the bony integration of several graft materials was investigated qualitatively by radiologic and histologic study. METHODS: Ten rabbits were included in this study; two holes were drilled bilaterally across the near cortex and the four holes in each rabbit were divided into four treatment groups (HAP, hydroxyapatite powder; HAC, hydroxyapatite cylinder; HA/TCP, hydroxyapatite/tri-calcium phosphate cylinder, and titanium cylinder). The volume of bone ingrowth and the change of bone mineral density were statistically calculated by computed tomography five times for each treatment group at 0, 2, 4, 6, and 8 weeks after grafting. Histologic analysis was performed at 8 weeks after grafting. RESULTS: The HAP group showed the most pronounced effect on the bone ingrowth surface area, which seen at 4, 6, and 8 weeks after graft (p < 0.05). On comparing the change of bone mineral density the bone ingrowth surface area among the 4 groups, there were no statistically significant differences among the groups found for any period (p > 0.05). On histological examination, the HAP group revealed well-recovered cortical bone, but the bone was irregularly thickened and haphazardly admixed with powder. The HAC group showed similar histological features to those of the HA/TCP group; the cortical surface of the newly developed bone was smooth and the bone matrix on the surface of the cylinder was regularly arranged. CONCLUSIONS: We concluded that both the hydroxyapatite powder and cylinder models investigated in our study may be suitable as a bone substitute in the rabbit tibial defect model, but their characteristic properties are quite different. In contrast to hydroxyapatite powder, which showed better results for the bone ingrowth surface, the hydroxyapatite cylinder showed better results for the sustained morphology.

PURPOSE: High-dose chemotherapy (HDT) and autologous stem cell transplantation (ASCT) have been used for the treatment of clinically aggressive non-Hodgkin's lymphoma (NHL). However, the superiority of specific conditioning regimens has not yet been established. The present study evaluated the efficacy and toxicity of a conditioning regimen involving fractionated total body irradiation (TBI), and the use of Ara-C and melphalan (TAM) for clinically aggressive NHL. MATERIALS AND METHODS: Between March 2002 and December 2004, 31 patients with aggressive NHL received fractionated TBI with a dose of 12 Gy over 3 days, and were administered 9 g/m2 Ara-C and 100 mg/m2 melphalan followed by autologous peripheral blood stem Cell Transplantation at the Catholic Hematopoietic Stem cell transplantation Center Korea. Patients that responded to first line chemotherapy and achieved complete remission (CR), or were in a first sensitive relapse were defined as having less advanced disease, while the other patients were defined as having more advanced disease. RESULTS: Objective responses were obtained in 24 of 31 patients (77.4%), comprising complete remission in 19 patients (61.3%) and partial remission in 5 (16.1%) patients. The median follow-up time was 28 months (range 1~62 months). At 3 years, the overall survival and event-free survival (EFS) rates were 62.3% and 47.3%, respectively. Patients with less advanced disease and more advanced disease showed 3-year EFS rates of 73.3% and 22.5 %, respectively (p=0.006). Early (within the first 100 days) treatment-related mortality occurred in 3 (9.7%) patients. Of the 31 total patients, 15 (48.4%) developed grade 3 mucositis, 22 (70.9%) developed neutropenic fever, and two (6.5%) developed interstitial pneumonia syndrome >grade 3. CONCLUSION: The modified TAM conditioning regimen and ASCT appear to be a feasible treatment regimen for clinically aggressive NHL, particularly for patients with less advanced disease.

PURPOSE: We wanted to evaluate the effective methods that are appropriate for an endemic area of thyroid disease and to compare the differences of cytologic diagnostic rates with and without using a peculiar smear technique. MATERIALS AND METHODS: We analyzed the incidence rate of insufficient results, complications and the total procedure times of 1,126 thyroid nodules in 776 patients who underwent US-FNAB (ultrasonography-guided fine-needle aspiration biopsy) from January to December 2005. We compared the diagnostic rate between the two groups; the groups' tests were performed with a peculiar smear technique (Group A, n = 313) or with a conventional smear technique (Group B, n = 250). RESULTS: According to the size of the thyroid nodule, the incidence rate of an insufficient result on US-FNAB and the mean total procedure time for 1126 thyroid nodules in 776 patients were measured as 16.9% (52/308) and 208 seconds for nodules under 0.5 cm, 9.8% (30/306) and 160 seconds for nodules between 0.5 cm-1.0 cm, and 6.0% (30/504) and 134 seconds for nodules over 1.0 cm. These 776 patients showed no significant complications, except for mild pain. In Group A, the incidence rate of an insufficient result was calculated as 15.1% (14/93) for the group with nodules under 0.5 cm, 5.3% (5/95) for the group with nodules between 0.5 cm-1.0 cm, 4.8% (6/125) for the group with nodules over 1.0 cm, and 8.0% (25/313) for the total A Group. In Group B, the incidence rate of an insufficient result was measured as 33.3% (15/45) for the group with nodules under 0.5 cm, 28.1% (25/89) for the group with nodules between 0.5 cm-1.0 cm, 21.4% (24/112) for the group with nodules over 1.0 cm, and 25.7% (63/245) for the total B group. There was a statistically significant correlation between the rate of an insufficient result and the peculiar smear technique or the size of the thyroid nodule. CONCLUSION: We consider that US-FNAB is very simple, safe and accurate diagnostic method for thyroid nodules, and US-FNAB with a peculiar smear technique is able to increase the diagnostic rate for thyroid nodules.

BACKGROUND: Radioiodine treatment is effective for the removal of remnant thyroid tissues after thyroidectomy in patients with differentiated thyroid carcinoma. To induce the elevation of serum TSH level which facilitates the uptake of radioiodine into remnants, a 4 to 6 week interval between thyroidectomy and radioiodine administration has been established. During the period of preparation, most patients have experienced overt symptoms of hypothyroidism which have led to the development of alternative strategies. Some reports have suggested that the interval could be reduced to about 3 weeks with less symptoms. We reevaluated the adequate time needed for the elevation of serum TSH level above 30microU/mL after thyroidectomy. METHODS: Forty five patients who had undergone total thyroidectomy for differentiated thyroid carcinoma were investigated. Serum TSH and free T4 levels were measured one or more times within 3 weeks after operation(total 97 blood samples). Eighty nine blood samples were obtained within 15 days. RESULTS: In 41 patients (91.1%) serum TSH levels increased to 30 microU/mL until 15 days after operation. Until postoperative 21 days, serum TSH levels in all the other patients reached 30microU/mL. In linear equation, the daily increment of serum TSH levels was 2.62microU/mL for the first 8 days after operation and 5.34micorU/mL for the next 7 days. The half-life of serum free T4 levels showed marked individual variations. CONCLUSION: Measurement of serum TSH level at about 15 days after total thyroidectomy for differentiated thyroid carcinoma may be useful in determining the time of radioiodine administration.
