The purpose of this study is to examine the prescription of Geoseohwajung-tang which often appears in Kim Yeoung-hun's medical records and how he employed this prescription. Geoseohwajung-tang is a prescription that can be found in no books of medicine in East Asia other than Kim Yeoung-hun's medical records, his posthumous work, Cheongganguigam, and Seungjeongwon Ilki, the diaries of royal secretariat of the Joseon dynasty. It was mostly used for digestive problems resulted from eating wrong food in summer and diversely applied by changing the composition of the medicinal ingredients according to the patient's symptoms. To see how Geoseohwajung-tang was used clinically, the researcher analyzed Kim Yeoung-hun's medical records written in 1915~1924. Among his total 21,369 medical records, 549 ones included Geoseohwajung-tang, and all of them were in July to September, so we can see that it was a prescription for the summer season. The use of the prescription was not highly related with the patient's gender, occupation, or age. The names of the diseases are mostly diarrhea, dysentery, acute vomiting with diarrhea, and all of them are highly related with diarrhea. The causes of them are mostly summer-heat, dampness, and food poison.

Porcine epidemic diarrhea virus (PEDV) causes an acute and lethal watery diarrhea in piglets that is great economic losses to the swine country worldwide. The spike (S) glycoprotein is an important determinant for PEDV biological properties. In the present study, we determined the full-length S gene sequences of five Chung-nam PEDV field isolates collected in 2016. The S gene was amplified by RT-PCR, purificated, sequenced, analyzed and then compared with published sequences of other PEDV strains. 5 field strains share 98.5%~99.9% homologies with each other at the nucleotide sequence level and 96.7%~99.9% homologies with each other at the amino acids sequence level. Most field strains have nucleotide insertions, deletions and mutation regions, and show lower homologies (93.1~93.8%) with classical and vaccine strains, however higher homologies (99.1%~99.5%) with US PEDV isolates in 2013. By phylogenetic tree analysis based on nucleotide sequence, five PEDV field isolates were clustered into Genogroup 2b but differ genetically from the vaccine strains (SM-98 and DR-13).

Background: The risk of imported infectious diseases has been increasing with the annual rise in the number of international travelers. Objectives: This study aims to analyze the distribution and characteristics of intestinal bacteria isolated in 2019 from residents of Chungcheongnam-do Province with experience of travelling overseas. Methods: Twenty-three former overseas travelers with diarrhea were analyzed to detect viruses and bacteria according to the Manual for Detection of Foodborne Pathogens at Outbreaks. Additionally, antibiotic susceptibility tests and 16s rRNA sequencing were performed. Results: Twenty-five strains of ten pathogens were isolated from 18 samples. Pathogenic E. coli was the most common at 57.7%, followed by Clostridium perfringens (15.4%), Campylobacter spp. (7.7%), and Salmonella spp. (7.7%). The serotype of Salmonella was confirmed as Salmonella Braenderup, II 9,46:g,[m],[s],t:[e,n,x]. Conclusions: It was confirmed that the major enteric bacterial pathogens isolated from overseas travelers in Chungcheongnam-do Province were pathogenic E. coli, as found in other studies. The study on Plesiomonas shigelloides is meaningful in that it is reported as a rare case of infection in Korea. Antibiotic resistance and 16s rRNA analysis were performed, which is expected to provide important basic data for the prevention of traveler's diarrhea.

Bovine viral diarrhea virus (BVDV) is an RNA virus belonging to Pestivirus in the family Flaviviridae. BVDV has economic significance for the livestock industry because of its association with acute disease, fetal loss, and birth of persistently infected (PI) animals. This study aimed to investigate the BVDV infection rates in Korean native cattle farms in Jeju for further planning of a BVDV control program in the Jeju Province. BVDV antibodies and antigens were tested in 15,842 sera collected from 302 Korean native cattle herds between January 2014 and June 2017 using enzyme-linked immunosorbent assay (ELISA). Viral antigen was detected by reverse transcription-polymerase chain reaction from 60 sera that were antigen ELISA-positive. BVDV antibodies were found in 90.7% (274/302) herds and 61.1% (9,678/15,842) cows. BVDV antigens were found in 13.2% (40/302) herds and 0.4% (61/15,842) cows. The oldest animal group (> 8 years) exhibited the highest sero-positive rates (91%), while the youngest animal group (< 1 years) had the highest antigen positivity rates (0.52%). Of the 60 antigen-positive sera, BVDV types 1 and 2 were found in 36 and 12 sera, respectively. Additionally, six animals were considered to be PI as BVDV was continually detected in annual examination.

Objectives : Samanhyeol is a combination of acupoints located in the cubital and popliteal fossa. It is commonly used in clinical practice to treat acute illnesses such as summerheat stroke, vomiting, diarrhea, and hemorrhagic diseases. There are two types of Samanhyeol in literature: BL40 and LU5, and BL40 and PC3. We investigated which acupoint is representative of Samanhyeol, and more closely fits the definition of Samanhyeol between LU5 and PC3. Methods : We searched for literature related to Samanhyeol, compared the anatomical locations of LU5, PC3, and BL40, examined their indications associated with the effectiveness of Samanhyeol, and checked cases in the literature where LU5 or PC3 was used concurrently with BL40. Results : BL40, one of the Samanhyeol, has been used to treat summerheat stroke, vomiting, diarrhea, and epistaxis in acupuncture texts, and there are many references in the literature to BL40 being used for bloodletting. And BL40 is located in the midpoint of the traverse crease of the popliteal fossa. From this perspective, LU5 may be a more suitable than PC3 because it is located in the midpoint of the cubital crease. However, Samanhyeol is a combination of acupoints used to treat heat stroke, vomiting and diarrhea, and hemorrhagic diseases. Upon analyzing the literature, it was found that LU5 and PC3 have similar efficacy. However, PC3 was used more frequently in cases of severe fever, unconsciousness or syncope. Conclusions : Literature suggests that BL40 is the representative acupoint for Samanhyeol. And PC3 is more appropriate than LU5 for Samanhyeol because its effects are more stronger on heat stroke although both LU5 and PC3 can treat symptoms related to Samanhyeol.

Purpose : Our aim was to describe the clinical features of noroviral gastroenteritis in children. Methods : This study included 22 children with noroviral gastroenteritis, as confirmed by stool RT-PCR, who were admitted to Bundang CHA Hospital between July 2006 and June 2008. Their medical records were reviewed and compared with those of 45 children with rotaviral gastroenteritis. Results : In the norovirus group, 19 (86.4%) children showed vomiting and 21 (95.5%) children showed diarrhea, while all children in the rotaviral group showed both vomiting and diarrhea. The duration of vomiting was not different in the two groups, but mean episodes of vomiting/24 h were higher in the norovirus group than in the rotavirus group. The duration of diarrhea was longer and mean episodes of diarrhea/24 h were higher in the rotavirus group. The Vesikari Scale was not different in the two groups. Frequency and duration of fever did not show a significant difference. Most children in both groups were below 2 years of age. Conclusion : Clinical features of noroviral gastroenteritis were largely similar to those of rotaviral gastroenteritis, but vomiting was more severe in noroviral infection, and diarrhea was more severe and prolonged in rotaviral infection. With regard to noroviral infection, further epidemiologic investigations and preventive efforts are essential.

Porcine epidemic diarrhea virus (PEDV) infection causes acute enteritis with lethal watery diarrhea resulting in a high mortality rate in piglets. As with the other members of group 1 coronaviruses, PEDV also utilizes the host aminopeptidase N (APN) as the major cellular receptor for entry into target cells. The coronavirus spike (S) protein is known to interact with the cellular surface for viral attachment and the S1 domain of all characterized coronaviruses contains a receptor-binding domain (RBD) that mediates a specific high-affinity interaction with their respective cellular receptors. Although the RBDs of several coronaviruses have been mapped, the location of the PEDV RBD has to date not been defined. As a first step toward the identification of the region of the S protein of the PEDV that is critical for recognition with the cellular receptor, we generated a series of S1-truncated variants and examined their abilities to bind to the porcine APN (pAPN) receptor. Our data indicate that the N-terminus of the S1 domain is required for pAPN association. The results from the present study may assist in our understanding of the molecular interactions between the PEDV S protein and the pAPN receptor.

Infantile Convulsion, one of common emergency symptoms in pediatrics, arises from sudden derangement of the central nerve system, and can cause a sudden loss of consciousness and spasm. It falls into three categories: Acute Infantile Convulsion, Chronic Infantile Convulsion and Chronic Spleen Convulsion. According to research, approximately 6~7% of all babies undergo spasm more than once. Since the treatment must be done immediately, acupuncture & moxibustion treatment can be one of the most important treatments in this Particular case. Therefore, the focus of this study is on how acupuncture & moxibustion can be utilized in the treatment of Infantile Convulsion, and the literary findings are as follows: 1. The meridian points used on acute infantile convulsion are Sugu(GV26), T'aech'ung(Liv3), Hapkok(LI4). 2. The meridians used on acute infantile convulsion are Governor Vessel(GV), Bladder Meridian(BL), Stomach Meridian(ST). 3.

Objectives : Coptidis Rhizoma has been used for stomach disease. However, its property is so cold that it might be avoided to prescribe for the elderly and the infirm having indigestion or diarrhea. Accordingly, the present study was designed to investigate the protective effects of Coptidis Rhizoma herbal acupuncture extract against acute gastric mucosal lesions induced by compound 48/80 in rats. Methods : The Coptidis Rhizoma herbal acupuncture (CRHA) was injected in Choksamni and Chungwan 1 h before compound 48/80 treatment. The animals were sacrificed under anesthesia 3 h after compound 48/80 treatment. The stomachs were removed and the amount of gastric adherent mucus, gastric mucosal hexosamine, SOD, XO, TBARS and histological examination were performed. Results : The decline of gastric adherent mucus, gastric mucosal hexosamine and the histological defects of gastric mucus were significantly protected by CRHA treatment. Gastric adherent mucus in control group was reduced to $38.2{\pm}5.0%$. CRHA groups significantly protected the loss of mucus to $77.5{\pm}4.9%$. Mucosal hexosamine content showed similar patterns. Mucosal hexosamine content in control group was reduced to $45.2{\pm}6.2%$. CRHA groups significantly protected the loss of mucus to $83.0{\pm}7.0%$. The changes of gastric mucosal SOD and TBARS were recovered by CRHA treatment as well. Conclusions : CRHA showed the protective effects on the acute gastric mucosal lesions induced by compound 48/80 in rats. These results suggest that CRHA may have protective effects on the gastritis.

Objectives: Can addition of neurokinin-1 receptor antagonists (NK1-RAs) be considered as an ideal strategy for the prevention of chemotherapy-induced nausea and vomiting (CINV)? Researchers differ on this question. Materials and Methods: Electronic databases were searched for randomized control trials (RCTs) that evaluated the effectiveness and safety of NK1-RAs in preventing CINV. The primary end point was complete response (CR) in the acute, delayed, and overall phases after chemotherapy. Subgroup analyses evaluated the types of NK1-RAs, routines of administration, types of malignancies, regimens used in combination with NK1-RAs, and age of patients included in the studies. The incidences of different types of adverse events were also extracted to estimate the safety of NK1-RAs. Results: A total of 38 RCTs involving 13,923 patients were identified. The CR rate of patients receiving NK-RAs was significantly higher than patients in the control groups during overall phase (70.8% vs 56.0%, P<0.001), acute phase (85.1% vs 79.6%, P<0.001), and delayed phase (71.4% vs 58.2%, P<0.001). There were three studies including patients of children or adolescents, the CR rate was also significantly higher in the treatment group (overall phase: OR=2.807, P<0.001; acute phase: OR=2.863, P =0.012; delayed phase: OR=2.417, P<0.001). For all the other outcomes, patients in the NK1-RAs groups showed improvements compared to the control groups (incidence of nausea: 45.2% vs 45.9%, P<0.001; occurrence of vomiting: 22.6% vs 38.9%, P<0.001; usage of rescue drugs: 23.5% vs 34.1%, P<0.001). The pooled side effects from NK1-RAs did not significantly differ from previous reports and the toxicity rates in patients less than eighteen years old also did not diff between the two groups (P=0.497). However, we found that constipation and insomnia were more common in the patients of control groups, whereas diarrhea and hiccups were more frequently detected in patients receiving NK1-RAs. Conclusions: NK1-RAs improved the CR rate of CINV. They are effective for both adults and children. The use of NK1-RAs might be associated with the appearance of diarrhea and hiccups, while decreasing the possibility of constipation and insomnia.
