Sudden sensorineural hearing loss may be defined as a severe loss of hearing occurring within a short space of time without any obvious cause. Its etiology is not verified yet, treatment and prognosis are uncertain. Objectives: We reviewed 6 cases of patients who hospitalized in Kyunghee Oriental Medical Center Dept. of Otolaryngology. Using the criteria of Siegel and Research Team of the Japanese Ministry of Health and Welfare of Japan, We are to evaluate the effect of Herb medication, Acupuncture therapy, and Negative therapy. We also attempted to search effective methods of therapy of sudden sensorineural hearing loss. Methods: We treated them with Oyaksunki-san(烏藥順氣散) for softening qi-stagnation and supressing 'Wind'(順氣治風), Chungsimjihwang-tang(淸心地黃湯) for strengthening 'Heart' and 'Kidney'(補心益腎), Boikyangwi-tang(補益養胃湯) for strengthening 'Wi-qi' and 'Stomach'(補衛(胃)氣). We also used acupuncture therapy and negative therapy based on the textbook of Acupuncture and Moxibustion. Results: One patient recovered completely after 5 days therapy, two patient markedly, another two patient slightly and one patient had no improvement. Conclusions: To treat sudden hearing loss, we can use Oyaksunki-san(烏藥順氣散) in the early stage of the disease. We can treat with Chungsimjihwang-tang(淸心地黃湯) and Boikyangwi-tang(補益養胃湯) in the late period of the disease, and administer Jaeumgenby-tang(滋蔭健脾湯) for suppressing tinnitus. If there is evidence of viral infection and the patient have too severe hearing loss, We can also use steroid in combination with Herb medication in the early stage of the disease. The Western medicine demonstrated that the start time of treatment had influence on recovery. If we started Oriental medical treatment within a week from the onset of sudden deafness. we will obtain the desired results. As the Western medical treatment does, Oriental medical therapy may have no effect after one month from onset of the disease.

Pseudolaric acids of Pseudolarix kaempferi (Pinaceae) have been known as diterpenoids with potent anti-fungal-, anti-microbial, and cytotoxic activities. In the present study, the five MeOH extracts were prepared from the five plant part (root bark, stem bark, leaf, the inner part of root, and cone) to find the relation between the concentration of pseudolaric acids and cytotoxicity. Pseudolaric acids B and C were isolated from the root bark of P. kaempferi to use them as standard compounds. The five extracts were tested on cytotoxicity against six cancer cell lines, A549 (lung), HCT116 (colon), MDA-MB-231 (breast), SNU638 (stomach), and SK-hep-1 (liver) by SRB assay, but against K562 (leukemia) by SRB- or MTT assay. HPLC quantification were performed on a Shisheido Capcell PAK C18 column ($5{\mu}m$, $4.6mm{\times}250mm$) using 254 nm wavelength. The cytotoxicity ($IC_{50}$, $0.36{\mu}g/ml$ on K562 cell lines) of the root bark extract was potent and the content (101.1 mg/g extract) of pseudolaric acid B was very high in the root bark. These results suggest that the MeOH extract obtained from the root bark could be developed as the anti-cancer agent with a high quantity of pseudolaric acid B.

Trace element zinc deficiency or excess is implicated in the development or progression of some cancers. The exact role of zinc in the etiology of colon cancer is unclear. To cast light on this question, an experimental model of colon carcinogenesis was applied here. Six week old rats were given sub cutaneous injections of DMH (30 mg/kg body weight) twice a week for three months and sacrificed after 4 months (precancer model) and 6 months (cancer model). Plasma zinc levels showed a significant decrease (p<0.05) at 4 months and a greater significant decrease at 6 months (p<0.01) as compared with controls. In the large intestine there was a significant decrease in tissue zinc levels (p<0.005) and in CuZnSOD, and alkaline phosphatase activity (p<0.05) in the pre-cancerous model and a greater significant decrease in tissue zinc (p<0.0001), and in CuZnSOD and alkaline phosphatase activity (p<0.001), in the carcinoma model. The tissue zinc levels showed a significant decrease in the small intestine and stomach (p<0.005) and in liver (p<0.05) in the cancer model. 87% of the rats in the precancer group and 92% rats in the cancer group showed histological evidence of precancerous lesions and carcinomas respectively in the colon mucosa. This study suggests that the decrease in plasma zinc, tissue zinc and activity of zinc related enzymes are associated with the development of preneoplastic lesions and these biochemical parameters further decrease with progression to carcinoma in the colon.

Objective: We determined the impact of maintaining pasture-based dairy cows and calves together over 100 days on cow milk production, cow and calf behavior, and calf liveweight and carcass quality. Methods: Six Holstein-Friesian cows and their male calves were monitored for 106±8.6 days. Cows were temporarily separated twice a day for milking with calves remaining in the paddock. Cow and calf behaviors were recorded via scan sampling at 6 different timepoints, for the first 7 days and twice a week thereafter. Calves were weighed weekly and immediately processed for meat quality and rumen development analysis at 106±8.6 days. Daily cow milk yields were collected from enrollment until 109±8.6 days (3 days post-weaning). Results: The average daily gain of calves was 1.4±0.73 kg/d, with an average carcass dressing percentage of 59%. Calves had the greatest frequency of observed close proximity to cow and suckling in the first two weeks and decreased with experiment duration. During separation for milking, cow vocalizations and attempts to return to their calf decreased over time. Reticulorumen weight was on target for calf age, but as a proportion of total stomach weight was lower than industry averages of calves the same age due to the larger abomasum. Cows produced an average of 12±7.6 kg of milk yield per day over the 3-days before the calves were weaned and increased to mean of 31±8.3 kg/d the 3 days after weaning, indicating a consumption of close to 20 kg per calf per day. Conclusion: The impact of a pasture-based cow-calf rearing system on cow and calf behavior and the potential for high levels of calf liveweight gain when provided ad-libitum milk and feed were determined. Further research is required to determine the practicality of replicating such systems with large herds and impact on reared calves post-weaning.

Purpose: ${\alpha}$-fetoprotein (AFP)-producing gastric cancer is a rare tumor with high rates of liver metastasis and a poor prognosis. Many studies have been performed but there have been no comprehensive investigations of the clinicopathological and prognosis. Materials and Methods: Six hundred ninety four patients with gastric cancer who underwent a curative gastric resection in Hanyang University Hospital from February 2001 to December 2008 were evaluated retrospectively after excluding active or chronic hepatits, liver cirrhosis and preoperative distant metastasis. Among them, thirty five patients had an elevated serum level of AFP (>7 ng/ml) preoperatively. The clinicopathological features of AFP-producing gastric cancer were analyzed. Results: There was poorer differentiation, a higher incidence of lymph node metastasis, more marked lymphatic and vascular invasion in the AFP-positive group than in the AFP-negative group. The 5-year survival rate of the AFP-positive group was significantly poorer than that in the AFP-negative group (66% vs. 80%, P=0.002). A significantly higher incidence of liver metastasis was observed in the AFP-positive group than in the AFP-negative group (14.3% vs. 3.6%, P=0.002) with a shorter median time period from the operation to the metachronous liver metastasis (3.7 months vs. 14.1 months, P=0.043). Multivariate survival analysis revealed the depth of invasion, degree of lymph node metastasis and AFP-positivity to be the independent prognostic factors. Conclusions: AFP-producing gastric cancers have an aggressive behavior with a high metastatic potential to the liver. In addition, their clinicopathological features are quite different from the more common AFP-negative gastric cancer.

Purpose: Pre-operative lymph node (LN) size is a valuable parameter for determining treatment strategy for gastric cancer. However, a correlation between LN size and metastasis has not been established. Materials and Methods: Thirty-six LN-positive (LNP) and matched 36 LN-negative (LNN) patients were included, and pathology slides of the LNs of these patients were reviewed. All the LNs were measured along the long-axis (LA) and short-axis (SA), manually. Results: Average retrieved LNs were $37.3{\pm}19.8$ and $40.5{\pm}11.6$ in the LNN and LNP groups, respectively. In total 2,800 LNs, including 136 metastatic LNs (MLNs) and 2,664 non-metastatic LNs (nMLNs), were evaluated. Mean length was significantly more in MLNs along both, the LA and SA (MLN_LA vs. nMLN_LA: $4.97{\pm}3.84$ vs. $3.37{\pm}2.40mm$, MLN_SA vs. nMLN_SA: $3.86{\pm}3.19$ vs. $2.43{\pm}1.59mm$; P<0.001). However, 92.6% (126/136) and 95.6% (130/136) of MLNs were <10 mm along the LA and SA, respectively. In addition, only 22.2% of the LNP group exhibited an MLN as the largest LN. Conclusions: Pre-operative multi-detector computed tomography has limited ability in estimating the presence of metastasis in LNs because most MLNs are less than 10 mm, and only a small proportion of the LNP group exhibits an MLN as the largest MLN.

Objectives: The object of this study was to observe the suppressive effects of Yijintang-gamibang (YJGMB), Yijintang being traditionally used in the Korean Medicine for treating various digestive diseases, on the rat reflux esophagitis (RE) as compared with omeprazole, a well-known proton pump inhibitor. Methods: Three different dosages of YJGMB, 50, 100 and 200 mg/kg, were orally pretreated once a day for 28 days before pylorus and forestomach ligation. Seven groups of 8 rats each were used in the study. Six hrs after pylorus and forestomach ligation, changes to the stomach and esophagus lesion areas, gastric volumes, acid and pepsin outputs, invasive lesion percentages, fundic mucosa, esophageal submucosa and total thicknesses were measured by histomorphometry. The results were compared with omeprazole 10 and 30 mg/kg treated groups in which the effects on RE were already confirmed. Results: As results of pylorus and forestomach ligation, marked increases of esophageal and gastric mucosa lesion areas, gastric volumes, acid outputs, pepsin outputs were observed with histopathological changes of RE, such as hemorrhages, ulcerative lesions and edematous changes on the esophageal and fundic mucosa. However, these pylorus and forestomach ligation induced RE were dose-dependently inhibited by treatment of 50, 100 and 200 mg/kg of YJGMB. YJGMB 50 mg/kg showed similar suppressive effects as 30 mg/kg of omeprazole, but more favorable effects were observed as compared with omeprazole 10 mg/kg. Conclusion: The results suggest that YJGMB showed favorable suppressive effects on the RE induced by pylorus and forestomach ligation. It is therefore expected that YJGMB will show favorable effects on RE as corresponds to the suggestion of traditional Korean medicine. However, more detailed mechanism studies should be conducted in future with the screening of the biological active chemical compounds in herbs.

Purpose: Intraabdominal abscess is one of the most common reasons for re-hospitalization after gastrectomy. This study aimed to develop a model for estimating the probability of intraabdominal abscesses that can be used during the postoperative period. Materials and Methods: We retrospectively reviewed the clinicopathological data of 1,564 patients who underwent gastrectomy for gastric cancer between 2010 and 2012. Twenty-six related markers were analyzed, and multivariate logistic regression analysis was used to develop the probability estimation model for intraabdominal abscess. Internal validation using a bootstrap approach was employed to correct for bias, and the model was then validated using an independent dataset comprising of patients who underwent gastrectomy between January 2008 and March 2010. Discrimination and calibration abilities were checked in both datasets. Results: The incidence of intraabdominal abscess in the development set was 7.80% (122/1,564). The surgical approach, operating time, pathologic N classification, body temperature, white blood cell count, C-reactive protein level, glucose level, and change in the hemoglobin level were significant predictors of intraabdominal abscess in the multivariate analysis. The probability estimation model that was developed on the basis of these results showed good discrimination and calibration abilities (concordance index=0.828, Hosmer-Lemeshow chi-statistic P=0.274). Finally, we combined both datasets to produce a nomogram that estimates the probability of intraabdominal abscess. Conclusions: This nomogram can be useful for identifying patients at a high risk of intraabdominal abscess. Patients at a high risk may benefit from further evaluation or treatment before discharge.

The purpose of this study was to investigate to protective effects against porcine epidemic diarrhea virus (PEDV) infection in piglets by administration of the PEDV antiserum orally at 2 hrs, 24hrs and 36hrs after birth. six piglets administered the antiserum were experimentally infected with PEDV at five-day-old. Control group were four piglets infected with PEDV only. Clinical signs and gross, histopathological lesion and immunohistochemical findings were examined. The results obtained were as follows; 1. In clinical signs, piglets of the control group appeared the typical signs of severe watery diarrhea, depression and anorexia but piglets of the PEDV antiserum treated group recovered progressively. In mortality, control group showed 75%, but PEDV antiserum treated group showed 16.7%, respectively. 2. In gross findings, piglets of the control group appeared the typical findings of congestion, distension of lumen, containing curdes of undigested milk in stomach. But piglets of the PEDV antiserum treated group appeared milder than those of control group. 3. In histopathological findings, piglets of the control group appeared the typical findings of villous atrophy and fusion, congesion, exfoliation, vacuolation, squamation, loss of cilia and proliferation of crypt. But piglets of the PEDV antiserum treated group appeared milder than those of control group. 4. In immunohistochemical findings, piglets of the PEDV antiserum treated group showed more intensive in reaction for IgG and IgG than those of control group. The recation for IgA was stronger than that of IgG. It was concluded that oral administration of PEDV antiserum to piglets was effective in preventing PEDV infection and reduced their mortality.
