Clostridium perfringens has been identified as a causative organism in necrotic enteritis in chicken. The bacterium has been classified into five toxigenic types (A through E) based on the pattern of the production of major lethal toxins. Seroneutralization with mice or guinea pigs usually has been used to type the organism. Of the types, types A and C of the bacterium had been recognized as the major pathogenic types in chicken. In this experiment, we isolated nine field strains of C perfringens from chicken showing necrotic enteritis in clinical symptoms and pathologic findings and identified by biochemical tests. In order to type the organism, a multiplex polymerase chain reaction (PCR) was used with primers on major lethal toxin genes instead of seroneutralization. Amplification of only a toxin gene with the PCR suggested that the disease in chicken was due to type A of C perfringens in Korea. Furthermore, the PCR method can be replaced with seroneutralization to type C perfringens in future.

The Theory of Meridian can be classified into early form of pre- and present form of after-. The representative early form of meridian is Eleven Meridians in Mawangdui scrolls(馬王堆帛書) which use Six Qi Diagnosis(六氣辨證). because it did not adopt Visceral Pattern Identification(臟腑辨證). The present form of meridian is Twelve Meridians of . It has developed to investigate relations between Visceral and disease with Five Phase Theory. Analyzing the name of the Six Meridians in the Shanghanlun(傷寒論)On Cold Damage, there are no hands, feet and visceral signs. and it is almost identical to Eleven Meridians in Mawangdui scrolls. According to , Eleven Meridians use only Six Foot Meridians(足六經) to classify diseases. This fact was applied identically to the Six Meridians in the Shanghanlun. Therefore many doctors, especially Hanzhihe(韓祗和) and Zhangzhicong(張志聰) mentioned that "I have never seen a book on Shanghanlun discuss about Hand Meridians(手經)."

Dentatorubropallidoluysian atrophy (DRPLA) is a rare neurodegenerative disorder usually inherited in an autosomal dominant pattern. DRPLA has been shown to be associated with expansion of an unstable cytosine-adenine-guanine (CAG) trinucleotide repeat in a gene on chromosome 12p. We evaluated a family with DRPLA that affected three members; A 35-year-old female presented with seven year history of gait ataxia, dysarthria and mild cognitive impairment. The MRI of the brain revealed diffuse cerebellar atrophy with an incidental lipoma in the midbrain. Her 30-year-old brother presented with progressive cerebellar ataxia that developed at the age of 20. Her grandmother and mother were reported to have developed ataxia during the late period of their life, and died at the age of 60 and 55, respectively. The demonstration of an expanded CAG repeat in the gene for DRPLA was used to confirm the diagnosis.

Objectives: Postpartum thyroiditis patient's symptoms are very similar to symptoms of postpartum disease which can be called sanhupung. This study is to report the effect of herbal medicine on sanhupung patient diagnosed of postpartum thyroiditis. Methods: We treated a 32-year-old female patient who had symptoms of postpartum thyroiditis and sanhupung with Jaeumganghwa-tang and Jayumkeonbi-tang. Results: After herbal medicine treatment the symptoms of postpartum thyroiditis such as general weakness, hot flush on the palms and soles of the feet, fever pattern of malaria and symptoms of sanhupung such as arthralgia, depression, imsomnia, sweating were improved. Conclusions: This case report shows that herbal medicine can be used to treat patient with postpartum thyroiditis and Jaeumganghwa-tang, Jayumkeonbi-tang is effective for mitigating the symptoms of postpartum thyroiditis. However, patient is still in thyroxine treatment, and additional care is required.

Purpose: To clarify the influence of "Dongeuibogam" on three important medical books "Euimunbogam", "Jaejungshinpyeon" and "Bangyakhabpyeon", in Chosun Dynasty. Methods: To examine and compare the three medical books, with "Uterus" and "Gynecology" part in "Dongeuibogam" to investigate effects of theories and prescriptions of "Dongeuibogam" upon gynecology. Results: Firstly, "Dongeuibogam" positively and practically reestablished the medical books existing at that time and made the high use of them in practice. Secondly, the three medical books mostly follows the formation of "Pomun" and "Buinmum" in "Dongeuibogam". thirdly, the three medical books inclusively accepted the theory and prescriptions of "Dongeuibogam" and made use of them actively in practice. Furthermore they developed other points of view in 'disease pattern identification and treatment'(辨證施治). Conclusion: "Dongeuibogam" had great influence upon gynecology in the medical books at the latter term of Chosun dynasty. "Dongeuibogam" also have had huge influence upon the clinical practice in gynecology until now by making the foundation of gynecology in traditional Korean medicine.

Among the ancient ideas of East Asia, there is a myth about the symbol of the Four Gods who commands all directions in the east, south, west, and north, and this is also reflected in the medical field. However, although there is discussion about Qinglong Decoction (青龍湯), Baihu Decoction (白虎湯) and Xuanwu Decoction (玄武湯) in the 『Shanghan Lun (傷寒論)』, there is no content focusing on Zhuniao decoction (朱鳥湯). Considering the consistent perspective of 『Shanghan Lun』, which recognizes the disease-syndrome and seeks prescriptions based on yin and yang thinking, this is very unusual. Therefore, in this study, it was revealed that the concept of 'Sishen Decoction (四神湯)' itself was a concept that emerged when the authors of 『Shanghan Lun』 established the 'eight-principles syndrome differentiation (八綱辨證)' system in their recognition and response to diseases-syndromes. Based on this, I considered the following possibilities: They were able to present Qinglong decoction, Baihu Decoction and Xuanwu decoction, as appropriate prescriptions for 'exterior cold excess syndrome (表寒實證)', 'interior heat deficiency syndrome (裏熱虛證)', and 'interior cold deficiency syndrome (裏熱實證)'. However, it is possible that the name of the prescription 'Zhuniao decoction' was not intentionally used, because it was not possible to provide an appropriate prescription for 'exterior cold excess syndrome (表熱實證)'.

Subarachnoid hemorrhage (SAH) is a disease that causes bleeding in the subarachnoid space; 70%-80% of nontraumatic subarachnoid hemorrhages are caused by saccular aneurysms. If the patient has already experienced a ruptured aneurysm that causes subarachnoid bleeding, rebleeding can result in a high mortality rate and serious sequelae. Therefore, if the patient can undergo surgical or interventional treatment, it should always be performed. This patient was diagnosed with acute aneurysmal subarachnoid hemorrhage and hydrocephalus. The patient was hospitalized for uncontrolled headache and vertigo after aneurysm coil embolization and ventriculoperitoneal shunting. The patient was treated with Yangkyuksanwha-tang and acupuncture and was observed with a symptom checklist for 25 days. Headache improved, from a visual analog scale (VAS) score of 7 to 0. Vertigo also improved, from a numeric rating scale (NRS) of 6 to 2, and the vertigo pattern changed from rotational to nonrotational. This case suggests that Korean medicine treatment is helpful in managing subarachnoid hemorrhage sequelae.

Breakthroughs in stem cell technology have contributed to disease modeling and drug screening via organoid technology. Organoid are defined as three-dimensional cellular aggregations derived from adult tissues or stem cells. They recapitulate the intricate pattern and functionality of the original tissue. Insulin is secreted mainly by the pancreatic ${\beta}$ cells. Large-scale production of insulin-secreting ${\beta}$ cells is crucial for diabetes therapy. Here, we provide a brief overview of organoids and focus on recent advances in protocols for the generation of pancreatic islet organoids from pancreatic tissue or pluripotent stem cells for insulin secretion. The feasibility and limitations of organoid cultures derived from stem cells for insulin production will be described. As the pancreas and gut share the same embryological origin and produce insulin, we will also discuss the possible application of gut organoids for diabetes therapy. Better understanding of the challenges associated with the current protocols for organoid culture facilitates development of scalable organoid cultures for applications in biomedicine.

Osteopathia striata with cranial sclerosis (OS-CS) is a bone dysplasia characterized by a linear striated pattern of sclerosis, especially in the long bones, and cranial sclerosis. It has variable clinical findings but distinctive radiological findings. Multiple oral and dental findings have been associated with this disease and can be seen during dental and/or medical imaging of the head and neck. Dentists and clinicians must be familiar with these signs to differentiate them from pathosis or erroneous radiographs. In the following case, we present a patient with OS-CS that presented at The University of Florida College of Dentistry with multiple craniofacial manifestations of this syndrome that were seen on a panoramic radiograph, which is one of the most commonly requested radiographs by dentists.

This study was performed to find out the clusters with high parasite infection risk to discuss the geographical pattern. Clusters were detected using SatScan software, which is a statistical spatial scan program using Kulldorff's scan statistic. Information on the parasitic infection cases in Korea 2011-2019 were collected from the Korea Centers for Disease Control and Prevention. Clusters of Ascaris lumbricoides infection were detected in Jeollabuk-do, and T. trichiura in Ulsan, Busan, and Gyeongsangnam-do. C. sinensis clusters were detected in Ulsan, Daegu, Busan, Gyeongsangnamdo, and Gyeongsangbuk-do. Clusters of intestinal trematodes were detected in Ulsan, Busan, and Gyeongsangnam-do. P. westermani cluster was found in Jeollabuk-do. E. vermicularis clusters were distributed in Gangwon-do, Jeju-do, Daegu, Daejeon, and Gwangju. This clustering information can be referred for surveillance and control on the parasitic infection outbreak in the infection-prone areas.
