Personnel who had contributed Medical development in history are classified into four types in this paper. The first, it is personnel that studied the medicine or treated a patient like doctors, medical researchers, physicians, nurses, etc.. The second, it is personnel that made law or systems about medicine or published the medical books. The third, it is personnel that received the medical treatment like patients or their protectors. The last, it is personnel that are teachers, students, friends, and relatives of people above mentioned. The studies of medical personnel in history are important. Those are more effective and easier informations than medicine itself. This paper is the study on medical personnel about HyangYak medicine that soley made from HyangYak(鄕藥) and that of classifying the informations about these persons.

The link between upper airway disease (allergic rhinitis and sinusitis) and lower airway disease (asthma) has long been of interest to physicians. Many epidemiological and pharmacological studies have provided a better understanding of pathophysiologic interrelationship between allergic rhinitis and asthma. The vast majority of patients with asthma have allergic rhinitis, and rhinitis is a major independent risk factor for asthma in cross-sectional and longitudinal studies. The association between sinusitis and asthma has long been appreciated. Through the recent evidences, allergic rhinitis, sinusitis, and asthma may not be considered as different diseases but rather as the expression in different parts of the respiratory tract of same pathological process in nature. Various mechanisms have been proposed to explain the relationship between asthma and upper airway diseases, but the underlying mechanisms are not completely discovered. The implications for the one-airway hypothesis are important not only academically but also clinically for diagnostic and therapeutic purposes.

Knowledge of molecular mechanisms governing malignant transformation brings new opportunities for therapeutic intervention against cancer using novel approaches. One of them is gene therapy based on the transfer of genetic material to an organism with the aim of correcting a disease. The application of gene therapy to the cancer treatment has led to the development of new experimental approaches such as suicidal gene therapy, inhibition of oncogenes and restoration of tumor-suppressor genes. Suicidal gene therapy is based on the expression in tumor cells of a gene encoding an enzyme that converts a prodrug into a toxic product. Representative suicidal genes are Herpes simplex virus type 1 thymidine kinase (HSV1-tk) and cytosine deaminase (CD). Especially, physicians and scientists of nuclear medicine field take an interest In suicidal gene therapy because they can monitor the location and magnitude, and duration of expression of HSV1-tk and CD by PET scanner.

Fish-borne heterophyid trematodes are known to have a zoonotic potential, since at least 30 species are able to infect humans worldwide, with a global infection of around 7 million people. In this paper, a 'state-of-the-art' review of the South American heterophyid species is provided, including classical and molecular taxonomy, parasite ecology, host-parasite interaction studies and a list of species and their hosts. There is still a lack of information on human infections in South America with undetected or unreported infections probably due to the information shortage and little attention by physicians to these small intestinal flukes. Molecular tools for specific diagnoses of South American heterophyid species are still to be defined. Additional new sequences of Pygidiopsis macrostomum, Ascocotyle pindoramensis and Ascocotyle longa from Brazil are also provided.

In this paper, when a physician make a diagnosis of the pattern identification (PI) in Korean stroke patients, the development methods of the PI classification function is considered by diagnostic questionnaire of the PI for stroke patients. Clinical data collected from 1,502 stroke patients who was identically diagnosed for the PI subtypes diagnosed by two physicians with more than 3 years experiences in 13 oriental medical hospitals. In order to develop the classification function into PI using Korean Stroke Syndrome Differentiation Standard was consist of the 44 items (Fire heat(19), Qi deficiency(11), Yin deficiency(7), Dampness-phlegm(7)). Using the 44 items, we took diagnostic and prediction accuracy rate through of discriminant model. The overall diagnostic and prediction accuracy rate of the PI subtypes for discriminant model was 74.37%, 70.88% respectively.

Purpose: The United States of America have pre-migration screening program are mandated through legislation. The one of purpose of this program is to prevent the importation of certain communicable diseases. Examinations of migration applicants are performed by panel physicians who are licensed physicians in the countries of origin that have agreements with the government departments of the country of destination to undertake this activity. In recent decades, the number of US migrants has increased, however COVID-19 impacted this trend of international migrants. The Aim of this study is to examine trends of US applicants and outcomes of tuberculosis and sexual transmitted infections (STIs) screening in South Korean applicants for US visa. Methods: A total of 4,442 applicants participated in US visa health check-up in 2016 to 2020. Results: The numbers of applicant for US visa in males and females was 1,814 and 2,628. The positive results in tuberculosis and STIs screening was noted with 0.66% in nontuberculous mycobacteria (NTM), 0.03% in tuberculosis, 0.03% in gonorrhea, 0.08% in syphilis, and 0.74% in chlamydia. The age groups of 2 to 14 years showed higher positive rate (13.89%) in tuberculin skin test (TST) tests compared to the rate of interferon gamma release assay (IGRA) tests (0.44%, P<0.001). The positive ratio of NTM and abnormal chest X-ray (CXR) which required sputum tests among the applicants over 15 years old has trends to increase with age. The age groups of over 70 years showed high positive rate in NTM and abnormal CXR (4.10%, 20.51%). However, ages 15 to 49 years groups showed 0.00% to 0.30% in NTM and 1.08% to 3.91% in abnormal CXR. In the study population, the positive rates of STIs were 0.03%, 0.08%, and 0.74% in gonorrhea, syphilis, and chlamydia, respectively. Among the participants who underwent sputum smears and cultures were just 1 case of active tuberculosis (0.03%) and 25 cases of NTM infection (0.66%). Conclusion: This study found that rate of positivity in tuberculosis and STIs screening among South Korean applicants for US visa in 2016 to 2020. Regarding tuberculosis, the positivity of CXR among the aged 15 to 59 years applicants was lower than that among over 60 years old. Among 2 to 14 years, positivity of IGRA was very low. And IGRA test can reduce effort of further evaluation compared to TST test in South Korea, so IGRA test among young adults can be useful. High positive rates in STI among young adult could result in high active sexuality, especially chlamydia infection is most common. Therefore Chlamydia polymerase chain reaction should be considered formal protocol among the Korean applicant for US visa.

Post-stroke atrial fibrillation has been frequently reported especially in the patients with right insular infarct as an evidence of cerebrogenic mechanism affecting on cardiac rhythm. However, conversion to normal sinus rhythm after stroke in patients who had atrial fibrillation has not been reported. A 88-year-old men who had untreated atrial fibrillation was admitted to hospital due to left middle cerebral artery territory infarction. During admission, second ischemic attack occurred in right middle cerebral artery territory. At that time, his atrial fibrillation converted spontaneously to normal sinus rhythm. Restored sinus rhythm sustained until he died due to sepsis. This case is evidence supporting a theory that brain is associated with control of cardiac rhythm. If no risk factor is revealed by intensive investigation in patients with acute cerebral infarctions that cardioembolism is strongly suspected as a cause, physicians should concern transformation of atrial fibrillation to normal sinus rhythm after stroke.
