According to the principle of ascending water and descending fire, water has the property of wetting downward, which is the opposite of fire, which has the property of blazing upward. Thus, they work differently according to their innate properties. Nature and the human body maintain harmony through the interaction of ascending water and descending fire. When applied to the human body, the heart and kidney are the center of this principle. In other words, the heart above is the fire and the kidney downward is water. When the heart-fire harmonizes downward, the kidney becomes warm, enabling genuine vital functions to be active. When the kidney yin moves upward, the heart receives the nourishing yin to harmonize nutrients and blood. Thereby, physiological functions become normal throughout the blood meridians. However, in the ascending kidneywater and descending heart-yang of the heart and the kidney, the liver and lung are the major functional organs. In other words, the liver through the dispersing and raising yang functions moves water, which is the vital essence of the kidney, upward. And the lung, through the astriction?clearing of the lung and descending Qi?dispersing functions, moves the heart-fire downward. These functions are deeply related with changing seasons; thus, these functions can be explained with the ascending kidney-water and descending heart-yang of the five viscera.

Objectives: Although medical typologies based on indigenous biopsychological ideas have been described, their integrity has been questioned due to its theory-driven nature in categorization. Therefore, studies on the Sasang typology, a temperament-based traditional Korean medicine, are needed to examine whether it is possible to classify types of specific biopsychological profiles using data-driven analysis. Methods: Psychological measures of the Eastern Sasang Personality Questionnaire (SPQ) and Western NEO-Personality Inventory (NEO-PI) along with physical measures and Sasang types were acquired from 2,049 participants. Latent groups based on the SPQ and NEO-PI subscale scores were extracted using Latent Profile Analysis. Their psychosomatic features were then compared with those of Sasang types. Results: Three SPQ-based latent groups showed distinctive psychological and physical features consistent with those of Sasang types. However, four NEOPI-based latent groups presented only psychological features. Furthermore, SPQ-High and SPQ-Low latent groups demonstrated similar psychosomatic profiles to those of So-Yang and So-Eum Sasang types, respectively. Conclusions: This study illustrates that biopsychological profiles of Sasang types are supported by psychosomatic features of latent groups based on SPQ of Eastern psychology, signifying that the categorization of Sasang typology have acceptable validity and reliability.

In this study, we investigated the antioxidant activities and compared other physiological properties including anti-cancer and antimicrobial effects of several traditional Korean herb-combined remedies such as Gilgyung-tang (GGT), Daihwangmokdan-tang (DHMDT), Sagan-tang (SGT), Socheonryongtang (SCRT), Sihocheonggan-tang (SHCGT), Sipyukmiyuki-eum (SYMYKE) and Hwangheuk-san (HHS), which were recorded in “Dong-eui-bo-gam” for “Ongjeo”. Total phenolic contents of the herb medicines were in a rich order of GGT ＜ SYMYKE ＜ SCRT ＜ SHCGT ＜ DHMDT ＜ SGT ＜ HHS. Among them, HHS appeared highest in superoxide dismutase-like activity, ferric reducing antioxidant power, scavenging of 2,2’-diphenyl-1-picrylhydrazyl, and 2,2’-azinobis(3-ethylbenzothiazoline-6-sulfonate) cationic radical activity. Interestingly, there was a positive relationship between their total phenolic contents and their antioxidant activities. Although all of them showed anti-proliferative activities in human colon cancer HCT-116 cells, HHS was seven times higher than GGT. Antimicrobial activities against Escherichia coli and Helicobacter pylori were revealed only on SGT, SCRT, SYMYKE and HHS. Taken together, these findings reveal the potential use of traditional Korean herbal formulas as functional ingredients in antioxidant and physiological materials.

Recent criticisms of the conduct and use of risk assessment by regulatory agencies have led to a wide range of proposed remedies, including changes in regulatory statutes and the development of new methods for assessing risk. The mandate to this Committee was more limited. Our objective was to examine whether alterations in institutional arrangements or procedures, particularly the organizational separation of risk assessment from regulatory decision-making and the use of uniform guidelines for inferring risk from available scientific information, can improve federal risk assessment activities. Before undertaking to determine whether organizational and procedural reforms could improve the performance and use of risk assessment in the federal government, the Committee examined the state of risk assessment and the regulatory environment in which it is performed. In this chapter, we define risk assessment and differentiate it from other elements in the regulatory process, analyze the types of judgments made in risk assessment, and examine its current government context. Because one chronic health hazard, cancer, was highlighted in the Committee's congressional mandate and has dominated public concern about public health risks in recent years, most of our report focuses on it. Furthermore, because activities in four agencies--the Environmental Protection Agency (EPA), the Food and Drug Administration (FDA), the Occupational Safety and Health Administration (OSHA), and the Consumer Product Safety Commission (CPSC)--have given rise to many of the proposals for changes in risk assessment practices, our review focuses on these four agencies. The conclusions of this report, although directed primarily at risk assessment of potential carcinogens as performed by these four agencies, may be applicable to other federal programs to reduce health risks.

Early recognition and surgical treatment of Hirschsprung's disease prevents serious mortality and morbidity from enterocolitis and obstruction. Usually this disease is characterized by a single aganglionic segment of the colon extending distally to the anal margin. In surgical treatment, the surgeon performs a frozen section biopsy to confirm whether there are ganglion cells. If there are intervening ganglionic sites in aganglionic bowel, there may be confusion in diagnosis and treatment. The authors experienced one case of total colonic aganglionosis with skip area. A transverse loop colostomy was performed on a 7 day-old male baby with colon perforation due to Hirschsprung's disease. But intestinal obstruction persisted and required two more operations to find the true nature of the disease. There were aganglionic segments from the anal margin to the terminal ileum 3.7cm proximal to the ileocecal valve. The entire transverse colon and appendix were normally ganglionated.

Malignant myoepithelioma (myoepithelial carcinoma), is a very rare malignant epithelial accounting for less than 1% of all salivary gland tumors and has an intermediate malignant potential. We report a case of malignant myoepithelioma arising in the left parotid giand in a 54-year-old man, which was difficult to differentiate from pleomorphic adenoma and other malignant salivary gland neoplasms. Fine needle aspiration cytology of the parotid gland showed cellular smear, composed of overlapped sheets and clusters or individually scattered tumor cells without any acinic or ductal structures. The tumor cells were rather uniform, with distinct cell borders and moderate amount of cytoplasm. The eccentrically located nuclei were oval to round and pleomorphic and showed prominent nucleoli. A few clear cells were noted in the cellular aggregates Metachromatic matrix was seen between individual tumor cells in a lacelike fashion, resembling pleomorphic adenoma. According to the immunohistochemical staining, we recognized that the component cells are myoeplthelial in nature, showing reactivity for the S-100 protein, vimentin, and actin.

Meningioangiomatosis (MA) is a rare congenital tumor that occurs mostly in 5-15 year old children. There have been only 5 cases previously reported that described the cystic nature within these tumors. We present a case of a MA accompanied by a separate macrocyst. A normally developed 2 year-old female patient presented with partial and generalized seizures. The brain computerized tomogram and magnetic resonance imaging revealed the presence of a calcified mass accompanied by a cyst in the right parietal area, surrounded by low density and high attenuation edema and hemorrhage. Upon right parietal craniotomy, a $1.6cm{\times}1.2cm{\times}0.5cm$ sized plate-like, gray-white, slightly hard mass was seen and it was completely excised. Approximately 1 cm from the mass in the anterior lateral direction, a cyst was found and subsequent biopsy of the cyst wall revealed no tumor tissue, and therefore the cyst was not removed. Pathologic report demonstrated the meningioangiomatosis. Follow up examination 2 years later showed no recurrence of the tumor, and there was no evidence of neurological deficits. Authors suggest that cysts that arise in the surrounding tissues of tumors may not be tumor cysts, and do not require surgical removal.

Bioconversion of timosaponin A-III (TA-III), one of the major steroidal saponins isolated from the rhizomes of Anemarrhenae asphodeloides Bunge (Liliaceae), was investigated in Saccharomyces cerevisiae. Five bioconversion products, denoted compounds 2-6, were obtained. Biotransformation metabolite 2 was a stereoisomer of TAIII with a specific isotype F-ring and ${\beta}$-ranged $CH_3$-21, which rarely occurs in nature. The structure of 2 was elucidated by extensive spectroscopic analysis (H-H COSY, HSQC, HMBC), as well as by high-resolution mass spectral analysis. The growth inhibitory activity of compounds 1-6 was assayed against four human cancer cell lines, HepG2, H-1299, HT-29, and HCT-116. Compounds 1 and 2 obviously inhibited the growth of the four types of cancer cells with $IC_{50}$ values being less than 19${\mu}M$. A structure-activity relationship is discussed, and the spirostane-ring F in compounds 1 and 2 appears to be the critical bioactive moiety for the cell growth inhibitory property.

Since allergic rhinitis is a disease with a very high prevalence, it is common to find patients with allergic rhinitis among aviation workers. However, they are so afraid that the report of rhinitis will have a negative effect on the evaluation of one's work suitability. Therefore, aviation medical examiners (AMEs) must be able to accurately understand the nature of allergic rhinitis, and confidently explain that appropriate treatment of rhinitis has a positive effect on their performance. In the treatment of allergic rhinitis, there are some medications that may cause drowsiness, which may impair the accuracy and safety of the aviation service. Therefore, AMEs should accurately know safe drugs that do not cause drowsiness and prescribe them to patients. In addition, it is necessary to know exactly whether air workers may receive the latest treatments for allergic rhinitis, such as surgical treatment and immunotherapy, and be able to recommend these treatments appropriately. Therefore, in this paper, we first briefly describe the pathophysiology, genetics, causative antigen, symptoms, diagnosis, and treatment of allergic rhinitis. We also aimed to discuss safe medication and other treatment modalities for allergic rhinitis.

The present study has determined BUN, createinine, c-AMP and $PGE_2$ activities as a clinical signs of radiation toxicity caused by uranylnitrate in rats. The significant increasing of $PGE_2$ concentration in plasma between the administration of uranylnitrate and lead nitrate were shown radiotoxic in nature on the effect of radiation energy. The reduction of PGE activities in plasma in uranylnitrate treated rats after furosemide, aldosterone and glucagone I.P. administration have observed the stimulating effect of uranium excretion into cells.
