  • Objectives : This study was carried out to investigate the effects of Goihwa-san(GHS) against ulcerative colitis induced by DSS (dextran sulfate sodium). Method : The sample group was divided into three. The control group consisted of mice that were not inflammation-induced. The pathological group was composed of untreated colitis elicited mice. The experimental group was administered GHS after colitis elicitation. The effects on ulcerative colitis were evaluated by the morphological change of colonic mucosa, the anti-oxidant effect, HSP 70, NF-${\kappa}$B, COX-1, COX-2 and iNOS. Results : In terms of immunohistochemical changes, the distribution of COX-1 in mice treated with GHS increased noticeably more than that in the pathological group. The distributions of HSP70, NF-${\kappa}$B, COX-2, iNOS in mice treated with GHS more decreased than those in the pathological group. Regeneration of surface epithelial cell and goblet cell in mucosa was observed by optical microscope. The colonic lengths in GHS-treated mice were more elongated than those of DSS only treated mice. Conclusion : GHS is a candidate treatment for ulcerative colitis.

  • Background: NF-${\kappa}B$ inhibits apoptosis through induction of antiapoptotic proteins and suppression of proapoptotic genes. Various chemotherapy agents induce NF-${\kappa}B$ translocation and target gene activation. We conducted the present study to assess the predictive value of NF-${\kappa}B$ regarding pathologic responses after receiving neoadjuvant chemotherapy. Materials and Methods: We enrolled 131 patients with locally advanced invasive ductal breast carcinoma. Immunohistochemistry (IHC) was used to detect NF-${\kappa}B$ expression. Evaluation of pathologic response was elaborated with the Ribero classification. Results: Expression of NF-${\kappa}B$ was significantly associated with poor pathological response (p=0.02). From the multivariate analysis, it was found that the positive expression of NF-${\kappa}B$ yielded RR=1.74 (95%CI 0.77 to 3.94). Conclusions: NF-${\kappa}B$ can be used as a predictor of poor pathological response after neoadjuvant chemotherapy.

  • In order to investigate the clinico-pathological and immunohistochemical changes in the rats infected with Aujeszky’s disease virus(ADV), 100 heads of 4 weeks-old rats were inoculated intraperitoneally and intranasally, with the domestically isolated ADV, NYJ-1-87 strain, at $10^{3.0}$ or $10^{5.0}$$TCID_ {50}$/0.2ml. Results obtained through the experiments were summarized as follows : 1. Clinical signs such as dulness, anorexia, pruritus, fascial edema, dyspnea and ataxia were observed from the 2nd day and died at the 3rd to 5th day after ADV inoculation. By necropsy, congestion and hemorrhage were observed in the abdominal organs, while no specific changes were detected in the other organs. 2. In histopathological observation, degeneration and necrosis of the nervous cells, non-suppurative meningoencephalitis, microgliosis and perivascular cuffing were manifested in central nerve system but no specific changes were observed in the other organs. 3. By immunohistochemical staining using peroxidase antiperoxidase, the positive cells were detected in the tissues of kideny, spleen, urinary bladder and lung.

  • Based on the gross lesion, a survey of ulcer prevalence was carried out on pigs (3,161 heads) at a slaughterhouse in seoul from April to December in 1989. The pigs stomachs were observed anatomically and classified, according to the presence or absence of foreign bodies. Ulcer prevalence is usually classified according to size of pig farm, ages, and supplied month. The results in the studies were as follows, 1. Fundus followed the highest rate with 28.2%, esophagus with 24.5% each of cardiac and pyloric part with 7.8% and 4.1% in cases of gastric mucosa pathological studies examed total 3,161. In the acute ulcer prevalence, fundus follwed with 5.4%, esophagus with 2.6%, each of cardiac and pyloric part with 0.8% and 0.3%. When prevalent frequencies of fundus are compared with cardiac and pyloric part, they have meaning.(P <0.05). 2. In the survey pig of total 3,161, pathological changes of epithelium tissue foliowed 44.0%, erosion(11.5%), chronic ulcer(14.8%), acute ulcer(1.6%), scar formation (1.7%) and perforation (0.9%). 3. In general monthly prevalence rates of gastric lesion are higher in spring and fall than in summer. 4. In the size of pig farms, ulcer showed higher rate at professional farms than raising on the side. 5. When there are more fluid condition in stomach and they are old, the ulcer appeared for more. 6. Foreign bodies in stomach were sand, hairballs, and intestinal worms were detected (1%).

  • Stomach cancer is the fifth most common malignancy in the world. The incidence of stomach cancer is declining worldwide, however, gastric cancer still remains the third most common cause of cancer death. The tumor, node, and metastasis (TNM) staging system has been frequently used as a method for cancer staging system and the most important reference in cancer treatment. In 2016, the classification of gastric cancer TNM staging was revised in the 8th American Joint Committee on Cancer (AJCC) edition. There are several modifications in stomach cancer staging in this edition compared to the 7th edition. First, the anatomical boundary between esophagus and stomach has been revised, therefore the definition of stomach cancer and esophageal cancer has refined. Second, N3 is separated into N3a and N3b in pathological classification. Patients with N3a and N3b revealed distinct prognosis in stomach cancer, and these results brought changes in pathological staging. Several large retrospective studies were conducted to compare staging between the 7th and 8th AJCC editions including prognostic value, stage grouping homogeneity, discriminatory ability, and monotonicity of gradients globally. The main objective of this review is to evaluate the clinical and pathological implications of AJCC 8th staging classification in the stomach cancer.

  • Purpose: The aim of this study was to determine clinical significance of dual-probe esophageal pH monitoring and to compare four pH monitoring parameters between proximal and distal esophagus in pathological gastroesophageal reflux disease with recurrent respiratory symptoms. Methods: Among the thirty-four patients who were performed 24 hr pH monitoring, seventeen patients with pathological distal reflux were classified into two groups: Group I (n:12) had recurrent respiratory symptoms and Group II (n:5) hadn't recurrent respiratory symptoms. The ambulatory dual-probe esophageal pH monitoring was performed for 18~24 hr. A pathologic GER was defined when reflux index (percent of the investigation time a pH<4) exceeded the 95th percentile of normal value. Results: Among the sixteen patients with recurrent respiratory symptoms, twelve patients (75%) have pathological distal reflux. Whereas among the eighteen patients without recurrent respiratory symptom, five patients (28%) have pathological distal reflux. In the Group I, the significant differences between proximal and distal esophageal pH recordings persisted for all parameters, but didn't persist in group II except for longest episode. Comparing esophageal pH four parameters between group I and group II at the proximal esophageal site, all parameters didn't show statistically significant differences. Conclusion: Regardless of respiratory symptoms, patients with pathological distal reflux didn't show statistically significant differences in the all parameters at the proximal esophageal site. Therefore we may reconsider usefulness of dual probe pH meter in patients with recurrent respiratory symptoms.

  • Background: Breast cancer is the most common malignant tumor in females worldwide. Many differences exist in clinico-pathological characteristics of breast cancer patients between China and Western countries. This study aimed to analyze clinico-pathological characteristics of breast cancer from central China. Methods: Clinico-pathological information on breast cancer from three hospitals in central China was collected and analyzed. Results: From 1994 to 2012, 2,525 patients with a median age 50 years were included in this study. The 45-49-year age group and invasive ductal carcinoma not otherwise specified accounted for the highest proportions (19.1%, 480/2,525 and 81.0%, 1,982/2,446). Stages 0-I, II and III accounted for 28.0% (682/2,441), 48.4% (1,180/2,441), and 23.7% (578/2,441), respectively. Distribution of N stage showed that N0 accounted for 53.2% (1,344/2,525), and proportion of N0 rose from 51.1% (157/307) in 30-39-year age group to 64.3% (110/171) in ${\geq}$ 70-year age group, with an average increase of 2.1% in each age group. Modified radical mastectomy, radical mastectomy, breast-conserving surgery and simple mastectomy were performed for 71.8% (1,812/2,525), 18.0% (454/2,525), 5.2% (131/2,525) and 2.6% (66/2,525), respectively. Proportions of breast-conserving surgery in age ${\leq}$ 44-year group (68/132, 51.5%) and simple mastectomy in age ${\geq}$ 60-year group (57/89, 64.0%) were higher than in the other age groups. Breast cancers positive for estrogen receptor accounted for 53.0% (1,107/ 2,112). The comparisons among this study and other reports showed higher proportion of younger patients, lower proportion of breast-conserving surgery and positive estrogen receptor patients in China than western countries. Conclusions: Clinico-pathological characteristics in this study demonstrated clear differences between the center of China than Western countries. Additional classification systems should be developed to guide grading of early breast cancer more accurately, especially for N0 patients. Invasive ductal carcinoma is a focus for intensive research.

  • The aims of this study were 1) to compare irrational gambling beliefs of gamblers and non-gamblers, 2) to investigate the role of cognitive error on winning probability thinking error, and 3) to examine the relationship between attributional bias and gambling behavior. A total of 248 subjects were recruited for this study. All subjects were classified into non-gamblers, social gamblers and pathological gamblers, and administered self-report questionnaires to measure irrational gambling beliefs, the probability inference error, the attriburional style, and the attributional bias. A pathological gambler group scored highest on irrational gambling beliefs, especially the overestimation of self-ability factor, and a social gambler group and a non-gambler group follow. All three groups scored higher on the magnification of gambling skills than the mean (4.0) of the scale. Pathological gamblers and social gamblers scored higher on the probability thinking error than non-gamblers. Pathological gamblers displayed higher external attribution, lower internal attribution in their daily life events and higher internal attribution in failure situation than social gamblers and non-gamblers. The results indicate that cognitive errors would be a factor that differentiates pathological gamblers from social gamblers and non-gamblers. In predicting gambling behaviors, overestimation of self-ability of irrational gambling beliefs, internal attribution in failure situation, external attribution in daily live event, and probability thinking error were identified as significant factors. It is concluded that a public education about common cognitive bias featured in gamblers might be important in prevention of pathological gambling behaviors.

  • I got the following result from the bibliographic study about the meaning of Hwa(火) and Hwa- byung(火病) at the concept and the aspect of pathological and etiological factors.The results are as follows.1. The pathological characteristics of Hwa(火) mean the inflammed state, the excited mental condition and perinervous hyperfunction caused by exopathy produced by any of the six extermal etiological factors(外感六淫) and Hwa caused by interior injury(內傷火熱).2. Hwa caused by the fire emotions(五志之火); anger, gladness, contemplation, sadress, fear by menta complications brings to Hwa caused by the five viscera(五臟之火) and Hwa caused by the stagnation of the liver - energy(肝鬱之火) is the rpresentive Hwa caused by the five viscera and the six hollow organs(贓腑之火).3. A symptom caused by a pathogenic Hwa(火證) is understood in a pathological sense involved an inflammed disease and is considered as a pathological state of excess syndrome(實證) caused by exterior Hwa( 外火).4. The pathologic process of Hwa-byung(火病) as the mental disease is based upon our people's emotion; Han(恨) to be pathologized without being overcome and can be considered as the process of Hwa caused by long-term(鬱久而火化).5. Hwa-byung(火病) means a psychosomatic disorder resulting from stress reaction caused by personal relations in the climacterium.Form the above mentioned study, the meaning of Hwa(火) and Hwa-byung(火病) is set theoretically and it also needs to be maintained reserching and studying about Hwa-byung(火病) consistantly.

  • Angiostrongylus cantonensis invades the central nervous system (CNS) of humans to induce eosinophilic meningitis and meningoencephalitis and leads to persistent headache, cognitive dysfunction, and ataxic gait. Infected mice (nonpermissive host), admittedly, suffer more serious pathological injuries than rats (permissive host). However, the pathological basis of these manifestations is incompletely elucidated. In this study, the behavioral test, histological and immunohistochemical techniques, and analysis of apoptotic gene expression, especially caspase-3, were conducted. The movement and motor coordination were investigated at week 2 post infection (PI) and week 3 PI in mice and rats, respectively. The cognitive impairs could be found in mice at week 2 PI but not in rats. The plaque-like lesion, perivascular cuffing of inflammatory cells, and dilated vessels within the cerebral cortex and hippocampus were more serious in mice than in rats at week 3 PI. Transcriptomic analysis showed activated extrinsic apoptotic pathway through increased expression of TNFR1 and caspase-8 in mice CNS. Immunohistochemical and double-labeling for NeuN and caspase-3 indicated the dramatically increased expression of caspase-3 in neuron of the cerebral cortex and hippocampus in mice but not in rats. Furthermore, western-blotting results showed high expression of cleaved caspase-3 proteins in mice but relatively low expression in rats. Thus, extrinsic apoptotic pathway participated in neuronal apoptosis might be the pathological basis of distinct behavioral dysfunctions in rodents with A. cantonensis infection. It provides the evidences of a primary molecular mechanism for the behavioral dysfunction and paves the ways to clinical diagnosis and therapy for A. cantonensis infection.
