Objectives : To investigate the anti-inflammatory effects of Scutellaria baicalensis Georgi pharmacopuncture in lipopolysaccharide (LPS)-induced inflammatory rat model. Methods : Sprague-Dawley rats were divided into 4 groups; LPS control (n=6), LPS+Scutellaria baicalensis Georgi pharmacopuncture at BL23 (n=6, BL23), LPS+Scutellaria baicalensis Georgi pharmacopuncture at CV12 (n=6, CV12), and LPS+Scutellaria baicalensis Georgi pharmacopuncture at GV4 (n=6, GV4). Pharmacopuncture was given every two days for 4 weeks followed by inflammation induction by intraperitoneal LPS injection (5mg/kg). Blood, liver tissue, and peritoneal lavage fluid were taken and proinflammatory cytokines and other related factors were analysed. Results : For proinflammatory cytokines, CV12 pharmacopuncture group was significantly different compared with the control group in plasma IL-$1{\beta}$, IL-6, TNF-$\alpha$, and IL-10 5 h after LPS injection (P<0.05). For plasma IL-$1{\beta}$ and IL-6, CV12 pharmacopuncture group also showed significant difference at 2 h compared with the control (P<0.05). GV4 pharmacopuncture group was significantly different compared with the control at 5 h in plasma IL-$1{\beta}$, IL-6, and TNF-$\alpha$ and at 2 h in IL-10 (P<0.05). Liver cytokines were analyzed at 5 h after LPS injection; only CV12 pharmacopuncture group showed significant difference in IL-$1{\beta}$ (P<0.05) and others including IL-6, TNF-$\alpha$, and IL-10 had no difference compared with the control group. CD4/CD8 ratio and the phagocytic activities of polymorphonuclear neutrophils were not different from those of control group in all pharmacopuncture groups (P>0.05). Plasma NO3-/NO2- and intracellular adhesion molecule-1 of CV12 pharmacopuncture group were significantly lower than that of the control group (P<0.05). In the plasma concentration of prostaglandin E2, all 3 pharmacopuncture groups had significantly lower values than that of the control group (P<0.05), but there was no difference among pharmacopucnture groups. Monocyte chemoattractant protein-1 and cytokine-induced neutorphil chemoattractant-1 in peritoneal lavage fluid was significantly decreased in CV12 pharmacopuncture group compared with the control group (P<0.05). Conclusions : These results indicate that Scutellaria baicalensis Georgi pharmacopuncture at CV12 may have a potent anti-inflammatory effect in an LPS-induced inflammatory rat model.

It is well known that the apposition of bone at implant surface would be influenced by the microstructure of titanium implants. The purpose of this study was to compare bone healing around the screw-shaped titanium implant with three different surface topographies in the canine mandibles by histological and biomechanical evaluation. All mandibular premolars of six mongrel dogs were extracted and implants were placed one month later. The pure titanium implants had different surface topographies: smooth and machined ($Steri-OSS^{(R)}$: Group II); sandblasted and acid-etched ($ITI^{(R)}$, SLA: Group III) surface. The fluorescent dyes were injected on the 2nd (calcein), 4th (oxytetracycline HCI) and 12th (alizarin red) weeks of healing. Dogs were sacrificed at 4 and 12 weeks after implantation. The decalcified and undecalcified specimens were prepared for histological and histo-metrical evaluation of implant-bone contact. Some specimens at 12 weeks after implantation were used for removal torque testing. Histologically, direct bone apposition to implant surface was found in all of the treated groups. More mature and dense bone was observed at the implant-bone interface at 12 weeks than that at 4 weeks after implantation. Under the fluorescent microscope, thick regular green fluorescent lines which mean early bone apposition were observed at the implant-bone interface in Group III, while yellow and red fluorescent areas were found at the implant-bone interface in Group I and II. The average implant-bone contact ratios at 4 weeks of healing were 54.3% in Group I, 57.7% in Group II and 66.2% in Group III. In Group I, implant-bone contact ratio was significantly lower than Group II and III(p<0.05). The average implant-to-bone contact ratios at 12 weeks after implantation were 64.3% in Group I, 66.7% in Group II and 71.2% in Group III. There was no significant difference among the three groups. In Group I and II, the implant-bone contact ratio at 12 weeks increased significantly in comparison to ratio at 4 weeks(p<0.05). The removal torque values at 12 weeks after implantation were 90.9 Ncm in Group I, 81.6 Ncm in Group II and 77.1 Ncm in Group III, which were significantly different(p<0.05). These results suggest that bone healing begin earlier and be better around the surface-treated implants compared to the smooth surface implants. The sandblasted and acid-etched implants showed the most favorable bone response among the three groups during the early healing stage and could reduce the waiting period prior to implant loading.

Subclinical vitamin $B_{12}$ deficiency is common in the elderly worldwide. We investigated the change of serum vitamin $B_{12}$ concentration with aging and compared anthropometric data and clinical health indicators between normal (${\geq}$ 340 pg/mL) and low (< 340 pg/mL) serum vitamin $B_{12}$ groups in 470 Korean women aged 65 years and over living in a rural area. Serum vitamin $B_{12}$ concentration showed inverse correlation with age (r = -0.0992, p < 0.05). The normal $B_{12}$ group showed significantly (p < 0.05) higher red blood cell count, hemoglobin, and hematocrit compared to the low $B_{12}$ group, however, no difference in mean corpuscular volume was observed between the two groups. The normal $B_{12}$ group showed significantly lower serum homocysteine concentration (p < 0.01) and prevalence of vitamin D (p < 0.01) or folate deficiency (p < 0.001). Bone mineral density (T-score) was significantly higher (p < 0.05) in the normal $B_{12}$ group, compared with that in the low $B_{12}$ group, and showed positive correlation (r = 0.1490, p < 0.01) with serum vitamin $B_{12}$ concentration after adjusting for age, body weight, and body mass index. No differences in anthropometric data, physical activity, and smoking and drinking habits were observed between the two groups. In conclusion, it could be suggested that older female adults with normal serum vitamin $B_{12}$ level would be less anemic and osteoporotic and more resistant to hyperhomocysteinemia associated chronic diseases than those with low serum vitamin $B_{12}$ level.

In order to investigate experimental effects of Yangkyuksanwha-Tang, which is the typical prescription for diseased SOYANGIN, on diabetes rats, the observation and measurement was made on the content of volume of blood glucose, total cholesterol, triglyceride, phospholipid, total protein, electrolyte($K^+$, $Na^+$) in serum, by dosing the cooked Y.S.T. to diabetic rats, induced by streptozotocin and following result was obtained. 1. The volume of blood glucose, in the diabetes rats, was decreased significantly, and remarkable decrease of blood glucose was shown in the Y.S.T. (12.5ml/kg) dosed group, after 4weeks of experiment. 2. The volume of total cholesterol of blood serum was decreased notably, especially remarkable reduce of total cholesterol was shown in the Y.S.T. (12.5ml/kg) dosed group after a week. 3. The volume of triglyceride in the blood serum of diabetic rats, induced by the streptozotocin was decreased after 4 weeks, and remarkable decrease was shown in the Y.S.T. (12.5ml/kg) dosed group after 2 weeks of experiment. 4. The volume of the phospholipid in the diabetes rats, was decreased significantly in the Y.S.T. (12.5ml/kg) dosed group after 2 weeks of experiment. 5. The volume of total protein of diabetes rats, was increased in all group, and the remarkable increase was shown in the Y.S.T. (12.5ml/kg) dosed group after 4 weeks. 6. The volume of the sodium in the Y.S.T. (12.5ml/kg) dosed group, was notable in each Y.S.T. dosed group (1.25ml/kg, 12.5ml/kg) after a week experiment. According to above results, It is expected that Y.S.T. applied to SOYANGIN, can be used for medical treatment of diabetes with effect. But because the effect can be somewhat different depending upon dosage, appropriate operation on clinic is needed, for the best curing effect.

Background and Objectives The objective of this study was to examine the effect of early cochlear implantation (CI) performed in infants less than 12 months of age. Subjects and Method Twenty-five children who received their first CI before 12 months of age were included in this study (infant group). The speech perception and language outcomes of these children were compared with those of 14 children who received their first CI between 13 and 24 months of age (older group). All children received sequential bilateral CI with the inter-stage interval of less than 2 years. Speech perception was measured using Categories of Auditory Performance, monosyllabic word test and sentence test, and language ability was measured using Sequenced Language Scale for Infants, Preschool Receptive-Expressive Language Scale, or Receptive & Expressive Vocavulary Test, depending on the age at the time of testing. Results There were no significant differences in speech perception abilities between the infant group and the older group. The mean expressive language score of infant group was higher than that of the older group, but the difference was not statistically significant. However, the receptive language score of infant group was significantly higher than that of the older group. Conclusion Children who received CI before 12 months of age achieved better receptive language ability than those who received it after 12 months of age. Thus CI should be performed as early as before 12 months of age to achieve better language ability.

Background: Vitamin B12 deficiency has been associated with peripheral neuropathy, loss of sensation in the peripheral nerves, and weakness in the lower extremities. Methylcobalamin is the most effective analogue of vitamin B12 used to treat or prevent the complications associated with vitamin B12 deficiency. The current study aimed to compare the serum cobalamin levels after administration of two different regimes of methylcobalamin in peripheral neuropathy patients. Methods: The present study was a prospective, randomized, comparative study. The study consisted of two parallel groups, group A (methylcobalamin $500{\mu}g$ injection intramuscularly three times a week) and group B (methylcobalamin $1500{\mu}g$ injection intramuscularly once a week). A control group of healthy volunteers was also included. Results: A total of 24 patients (12 in each group) were included in the study. Five healthy volunteers were also included as a control in each group. At the end of treatment, serum cobalamin levels were significantly (P = 0.028) higher in group A ($1892.08{\pm}234.50$) as compared with group B ($1438.5{\pm}460.32$). The serum cobalamin levels in Group A healthy volunteers were also two times higher than that of group B (P = 0.056). Both the LANSS scale and DN4 questionnaire reported similar results at end of treatment. Conclusions: The $500{\mu}g$ methylcobalamin thrice weekly regime is more effective in increasing the serum cobalamin levels as compared to the $1500{\mu}g$ methylcobalamin once weekly regime.

Objective : Teriparatide is known as an effective anabolic agent not only for severe osteoporosis but also for bone healing and union. We explored the possibility of teriparatide as an alternative treatment option for osteoporotic thoracolumbar (TL) burst fracture. Methods : This retrospective study enrolled 35 female patients with mean age of 73.77±6.71 years (61-88) diagnosed as osteoporotic TL burst fracture with ≥4 of thoracolumbar injury classification and severity (TLICS) score and no neurological deficits. All patients were treated by teriparatide only (12 of group A), teriparatide plus vertebroplasty (12 of group B), or surgical fixation with fusion (11 of group C), and followed up for 12 months. Radiological outcomes were evaluated using radiological parameters including kyphotic angle (KA), segmental vertebral kyphotic angle (SVKA), compression ratio (CR), and vertebral body height (anterior [AH], middle [MH], posterior [PH]). Functional outcomes were evaluated using visual analog scale (VAS) and Macnab classification (MC). Results : There were no statistical significant differences in age, bone mineral density (-3.36±0.73), and TLICS score (4.34±0.48) among the three groups (p>0.05). Teriparatide was administered during 8.63±2.32 months in group A and B. In 12-month radiological outcomes, there were significant restoration in SVKA, CR, AH, and MH of group B and KA, SVKA, CR, AH, and MH of group C compared to group A with no radiological changes (p<0.05). All groups showed similar significant improvements in 12-month functional outcomes, although group B and C showed a better 1-month VAS, 1-month MC, 3-month MC compared to group A (p<0.05). Conclusion : Non-surgical treatment with teriparatide showed similar 12-month functional outcomes compared to surgical fixation with fusion. The additional vertebroplasty to teriparatide and surgical fixation with fusion were more helpful to improve short-term functional outcomes with structural restoration compared to teriparatide only.
