Most boys afflicted with panhypogammaglobulinemia, also known as X-linked agammaglobulinemia, remain healthy during the first 6 to 12 months of life because of protection by maternally transmitted IgG antibodies. Thereafter, they repeatedly acquire infections with high-grade pathogens, such as pneumococci, streptococci, and hemophilus unless given antibiotics or immunoglobulin replacement therapy. We experienced a case of panhypogammaglobulinemia in a 4 years old boy. He had been suffered from recurrent upper respiratory tract infection, otitis media and pneumonia since late infancy. He was admitted due to right pleural effusion with pneumonia, and streptococcus pneumoniae was isolated from pleural fluid and blood cultures. His immune status revealed panhypogammaglobulinemia and deficiency in mature B lymphocyte. He was treated with appropriate antibiotics therapy, but showed poor responses. He was transferred to department of thoracic surgery, and received minithoracotomy (decortication) operation. He was successfully treated with operation, antibiotics, and IV gammaglobulin infusions. Now he is being followed with periodic IV gammaglobulin replacement therapy.

Ginseng, the root of Panax species, is a well-known herbal medicine. It has been used as traditional medicine in Korea, China and Japan for thousands of years and now is a popular and worldwide natural medicine. The active principles of ginseng are ginsenosides which are also called ginseng saponins. Traditionally ginseng has been used primarily as a tonic to invigorate weak body functions and help the restoration of homeostasis. Current in vivo and in vitro studies demonstrate its beneficial effects in a wide range of pathological conditions such as cardiovascular diseases, cancer, immune deficiency and hepatotoxicity. Moreover, recent research indicates that some of ginseng's active ingredients exert beneficial actions on aging and neurodegenerative disorders such as Parkinson´s disease. Essentially, antioxidant, antiinflammatory, anti-apoptotic and immunostimulant activities are mostly underlying the postulated ginseng-mediated protective mechanisms. Next to animal studies, data from neural cell cultures contribute to the understanding of these mechanisms which involve decreasing nitric oxide, scavenging of free radicals and counteracting excitotoxicity. This paper focuses on own and other neuroprotective data on ginseng for dopaminergic neurons and intends to show aspects where neuroprotection e.g. by ginsenosides, additionally or preceding standard Parkinson therapy, could come about as a valuable contribution to slow neurodegenerative processes.

Ginseng, the root of Panax species, a well-known herbal medicine has been used as a traditional medicine for thousands of years and is now a popular and worldwide used natural medicine. Ginseng has been used primarily as a tonic to invigorate weak bodies to help the restoration of homeostasis in a wide range of pathological conditions such as cardiovascular diseases, cancer, immune deficiency and hepatotoxicity. Although conclusive clinical data in humans is still missing, recent research results have suggested that some of the active ingredients ginseng exert beneficial effects on central nervous system (CNS) disorders and neurodegenerative diseases, suggesting it could be used in treatment of psychotic disorders. Data from neural cell cultures and animal studies contribute to the understanding of these mechanisms that involve inhibitory effects on stress-induced corticosterone level increasing and modulating of neurontransmitters, reducing $Ca^{2+}$ over-influx, scavenging of free radicals and counteracting excitotoxicity. In this review, we focused on recently reported medicinal effects of ginseng and summarized the possibility of its applications on psychotic disorders.

The prevalence of lung diseases caused by nontuberculous mycobacteria (NTM) is increasing worldwide. Unlike pulmonary tuberculosis, endobronchial NTM diseases are very rare with the majority of cases reported in patients with human immunodeficiency virus infection and acquired immune deficiency syndrome. We reported a rare case of endobronchial Mycobacterium avium disease associated with lobar atelectasis in a young immunocompetent patient and reviewed the relevant literature.

Purpose: To promote condom use for young men, there is necessary to meet their varying needs for condom. The purpose of this study was to examine what predicts condom use intention according to experience of sexual intercourse among Korean male college students. The conceptual framework for the study was the theory of planned behavior and the health belief model. Methods: A cross-sectional descriptive design was used with self-report questionnaires, which were completed by 399 subjects. Logistic regression analysis was done to examine predictors of condom use intentions according to experience of sexual intercourse. Results: The susceptibility to sexual transmitted diseases/ Acquired Immune Deficiency Syndrome (STDs/AIDS) and pregnancy and benefits from condom use were significant predictors of condom use intentions in the non-experienced group. The significant predictors of condom use intention for the experienced group were barriers to condom use and condom use self-efficacy. Conclusion: These findings suggest that sex education program should be developed to overcome barriers to condom use, enhance condom use self-efficacy, and maximize the benefits from condom use as well as increase the perceived susceptibility to STDs/AIDS and pregnancy. To enhance condom use self- efficacy, practicing and increasing ability in interactive negotiation to use condom should be included.

Purpose: This study aims to identify factors influencing the stigma communication concerning HIV (Human Immunodeficiency Virus)/AIDS (Acquired Immune Deficiency Syndrome) patients between health and medical college students. Methods: In this descriptive study, the participants were 158 college students from a certain university. Data were collected from September 18 to September 30, 2018. Self-reported questionnaires were used to measure AIDS-related knowledge, homosexual awareness, fear of HIV/AIDS patients and stigma communication. The collected data were analyzed with descriptive statistics, an independent t-test, one way analysis of variance, Pearson's correlation and a stepwise multiple regression analysis using the SPSS 23.0 program. Results: The factors influencing the stigma communication between health and medical college students were a fear of HIV/AIDS patients (β=.47, p<.001) and homosexual awareness (β=-.15, p=.040), which together explained 28.0% of the variance in the model. Conclusion: The study findings suggest that an education program for health and medical college students should be developed. Additionally, when designing the education program, it is recommended that the contents for inducing attitude changes should include affective areas as well as knowledge-oriented contents. The study suggests that it is necessary to provide a systematic education program to decrease the stigma for HIV/AIDS patients before health care providers enter clinical practice.

Though bile acids have been well known as digestive juice, recent studies have demonstrated that bile acids bind to their endogenous receptors, including Farnesoid X receptor (FXR) and G protein-coupled bile acid receptor 1 (GPBAR1; TGR5) and serve as hormone to control various biological processes, including cholesterol/bile acid metabolism, glucose/lipid metabolism, immune responses, and energy metabolism. Deficiency of those bile acid receptors has been reported to induce diverse metabolic syndromes such as obesity, hyperlipidemia, hyperglycemia, and insulin resistance. As consistent, numerous studies have reported alteration of bile acid signaling pathways in type II diabetes patients. Interestingly, bile acids have shown to activate TGR5 in intestinal L cells and enhance secretion of glucagon-like peptide 1 (GLP-1) to potentiate insulin secretion in response to glucose. Moreover, FXR has been shown to crosstalk with TGR5 to control GLP-1 secretion. Altogether, bile acid receptors, FXR and TGR5 are potent therapeutic targets for the treatment of metabolic diseases, including type II diabetes.

Free fatty acid receptor 2 (FFA2, also known as GPR43), a G-protein-coupled receptor, has been known to recognize short-chain fatty acids and regulate inflammatory responses. FFA2 gene deficiency exacerbated disease states in several models of inflammatory conditions including asthma. However, in vivo efficacy of FFA2 agonists has not been tested in allergic asthma. Thus, we investigated effect of 4-chloro-α-(1-methylethyl)-N-2-thiazoylylbenzeneacetanilide (4-CMTB), a FFA2 agonist, on antigen-induced degranulation in RBL-2H3 cells and ovalbumin-induced allergic asthma in BALB/c mice. Treatment of 4-CMTB inhibited the antigen-induced degranulation concentration-dependently. Administration of 4-CMTB decreased the immune cell numbers in the bronchoalveolar lavage fluid and suppressed the expression of inflammatory Th2 cytokines (IL-4, IL-5, and IL-13) in the lung tissues. Histological studies revealed that 4-CMTB suppressed mucin production and inflammation in the lungs. Thus, results proved that FFA2 functions to suppress allergic asthma, suggesting 4-CMTB activation of FFA2 as a therapeutic tool for allergic asthma.

Retinoic acid receptor-related orphan receptor α (RORα) plays a vital role in various physiological processes, including metabolism, cancer, circadian rhythm, cerebellar development, and inflammation. Although RORα is expressed in the skin, its role in skin physiology remains poorly elucidated. Herein, Rorα was expressed in the basal and suprabasal layers of the epidermis; however, keratinocyte-specific Rorα deletion did not impact normal epidermal formation. Under pathophysiological conditions, Rorα-deficient mice exhibited alleviated psoriasis-like symptoms, including relatively intact epidermal stratification, reduced keratinocyte hyperproliferation, and low-level expression of inflammatory cytokines in keratinocytes. Unexpectedly, the splenic population of Th17 cells was significantly lower in keratinocyte-specific RORα deficient mice than in the control. Additionally, Rorα-deficiency reduced imiquimod-induced activation of nuclear factor-κB and STAT3 in keratinocytes. Therefore, we expect that RORα inhibitors act on immune cells and keratinocytes to suppress the onset and progression of psoriasis.
