Purpose: The purpose of this study is to investigate the anti-arthritis effects of Jeonsaenghwalhyeoltanggamibang(JHTG) on collagen-induced arthritis(CIA) in mice. Methods: To assess the effects of JHTG on CIA in mice, we conducted several experiments such as analysis of arthritis index, cell count of draining lymph node(DLN) and paw joint, measurement of serum antibody levels and observation of the histological changes of joint. Results: 1. JHTG extract had a suppressive effect on the arthritis index of paw joints in CIA mice. 2. JHTG extract increased the total cell number of DLN, and decreased the total cell number of paw joints in CIA mice. 3. JHTG extract increased the absolute number of various cell surface receptors in DLN, and decreased the absolute number of B220+/CD23+ cells in DLN in CIA mice. 4. JHTG extract decreased the absolute number of CD3+, CD4+, CD11b+/Gr-1 cells in paw joint in CIA mice. 5. JHTG extract didn't decrease the absolute number of CD4+/CD25+ cells in paw joints in CIA mice. 6. JHTG extract decreased levels of total IgM in the serum of CIA mice, but had no effect on levels of collagen II specific antibody. 7. JHTG extract decreased the destruction of articular cartilages and collagen fibers and the proliferation of synovial cells in paw joints from CIA mice. Conclusion: These results indicate that JHTG has clinical potential for the treatment of rheumatoid arthritis by modulating the immune response.

Background: Tuberculosis (TB) is the leading cause of mortality among human immunodeficiency virus (HIV) patients and the majority of them occur in developing countries. The aims of the present study were to determine the frequency of HIV/TB co-infection and other probable associated factors. Methods: This 10 year retrospective study was conducted on 824 HIV patients in the south-west of Iran. HIV infection was diagnosed by the enzyme linked immunosorbent assay and confirmed by Western blot. TB diagnosis was based on consistency of the clinical manifestations, chest X-ray, and microscopic examination. Drug susceptibility testing was done by the proportional method on $L{\ddot{o}}wenstein$-Jensen media. Results: Of 824 HIV patients, 59 (7.2%) were identified as TB co-infected and the majority (86.4%) of them were male. Of the overall TB infected patients, 6 cases (10.2%) showed multidrug-resistant with the mean CD4+ lymphocyte count of $163{\pm}166cells/mm^3$. The main clinical forms of TB were pulmonary (73%). There was a significant (p<0.05) correlation between TB infection and CD4+ lymphocyte counts ${\leq}200cells/mm^3$, gender, prison history, addiction history, and highly active anti-retroviral therapy. Conclusion: We reported novel information on frequency of HIV/TB co-infection and multidrug resistant-TB outcome among co-infected patients that could facilitate better management of such infections on a global scale.

The purpose of this study is to investigate the effects of Ginseng saponin on the cadmium which is widely distributed in the environment, results in immune system alteration. For the experiments, 125 mice of ICR strain were used. The experimental groups were divided into 5 groups a control, a cadmium alone treatment group, three Cd and saponin (10, 50, 100 mg/kg) combined treatment groups. The mice were allocated 25 to each group and observed for 8 weeks. The results of experiment are as follows: 1. Body weight growth rates during 8 weeks were as this control group 36.47%, Cd alone group 32.48%, saponin combined treatment group (10, 50, 100 mg/kg) 32.49%, 39.17%, 24.27% respectively. 2. In all groups, the relative weights of liver and kidney were increased, compared with control group. In the case of spleen, saponin combined treatment group (50, 100 mg/kg) was high to the significant level compared with a control group (p<0.05). Thymus was not. 3. On blood lymphocyte count observation, Cd alone treament group has 25.6% less than control group, and saponin combined treatment group have increasing trends. but in thymus and spleen, there was no trends like blood. 4. On antibody titer, there was no difference among groups. 5. On total serum protein, saponin (100 mg/kg) combined treatment group was high to significant level compared with control group (p<0.05), and other treatment groups have increasing trends. 6. Cd accumulation in kidney was higher than in liver, and all treatment groups were high to the very significant level compared with the control group (p<0.05), but there was no difference among groups. From the results of this study, it can be concluded that the oral administration of Cd results in alteration of immune system and Ginseng saponin prevents this effect. But, Cd accumulation was not affected by saponin.

Background: Patients with colorectal cancer are usually treated with chemotherapy, which reduces the number of blood cells, especially white blood cells, and consequently increases the risk of infections. Some research studies have reported that aromatherapy massage affects the immune system and improves immune function by, for example, increasing the numbers of natural killer cells and peripheral blood lymphocytes. However, there has been no report of any study which provided good evidence as to whether aromatherapy with Thai massage could improve the immune system in patients with colorectal cancer. The objectives of this study were to determine whether the use of aromatherapy with light Thai massage in patients with colorectal cancer, who have received chemotherapy, can result in improvement of the cellular immunity and reduce the severity of the common symptoms of side effects. Materials and Methods: Sixty-six patients with colorectal cancer in Phichit Hospital, Thailand, were enrolled in a single-blind, randomised-controlled trial. The intervention consisted of three massage sessions with ginger and coconut oil over a 1-week period. The control group received standard supportive care only. Assessments were conducted at pre-assessment and at the end of one week of massage or standard care. Changes from pre-assessment to the end of treatment were measured in terms of white blood cells, neutrophils, lymphocytes, CD4 and CD8 cells and the CD4/CD8 ratio and also the severity of self-rated symptom scores. Results: The main finding was that after adjusting for pre-assessment values the mean lymphocyte count at the post-assessment was significantly higher (P=0.04) in the treatment group than in the controls. The size of this difference suggested that aromatherapy with Thai massage could boost lymphocyte numbers by 11%. The secondary outcomes were that at the post assessment the symptom severity scores for fatigue, presenting symptom, pain and stress were significantly lower in the massage group than in the standard care controls. Conclusions: Aromatherapy with light Thai massage can be beneficial for the immune systems of cancer patients who are undergoing chemotherapy by increasing the number of lymphocytes and can help to reduce the severity of common symptoms.

Cryptococcus neoformans infection usually occurs in patients with advanced human immunodeficiency virus (HIV) infection or with a CD4 T lymphocyte count of <100 cells/µL. Pulmonary and central nervous system infections are the most frequently encountered forms of cryptococcosis; however, colonic cryptococcosis is uncommon. We describe the case of a 41-year-old antiretroviral-naïve man with HIV infection diagnosed eight years prior and intermittent diarrhea for 4 months who presented to the emergency department with a 1-day history of low-grade fever and confusion. Brain magnetic resonance imaging and cerebrospinal fluid analysis revealed normal results; however, he was diagnosed with Pneumocystis jirovecii pneumonia based on chest computed tomography and bronchoalveolar lavage analysis. Trimethoprim-sulfamethoxazole administration was initiated followed by antiretroviral treatment. Although his condition gradually improved, he developed fever and abdominal discomfort, and the diarrhea worsened. Endoscopy revealed a small ulcer in the distal transverse colon. Histopathological examination of a colon tissue sample revealed cryptococcal infection. He improved substantially during liposomal amphotericin B and fluconazole treatment. We encountered a rare case of colonic cryptococcosis that caused chronic diarrhea in a patient with advanced HIV infection. Colonic cryptococcosis should be considered when patients with acquired immune deficiency syndrome present with gastrointestinal symptoms.

Objectives: The survival outcomes of antiretroviral treatment (ART) programs have not been systematically evaluated at the state level in India. This retrospective study assessed the survival rates and factors associated with survival among adult human immunodeficiency virus (HIV)-infected patients in Andhra Pradesh, India. Methods: The present study used data from 139 679 HIV patients aged ${\geq}15$ years on ART who were registered from 2007 to 2011 and were followed up through December 2013. The primary end point was death of the patient. Mortality densities (per 1000 person-years) were calculated. Kaplan-Meier and Cox-regression models were used to estimate survival and explore the factors associated with survival. Results: The overall median follow-up time was 16.0 months (2.0 months for the deceased and 14.0 months for those lost to follow-up). Approximately 13.2% of those newly initiated on ART died during follow-up. Of those deaths, 56% occurred in the first three months. The crude mortality rate was 80.9 per 1000 person-years at risk. The CD4 count (adjusted hazard ratio [aHR],4.88; 95% confidence interval [CI], 4.36 to 5.46 for < $100cells/mm^3$ vs. > $350cells/mm^3$), functional status (aHR, 3.05; 95% CI, 2.82 to 3.30 for bedridden vs. normal), and body weight (aHR, 3.69; 95% CI, 3.42 to 3.97 for <45 kg vs. >60 kg) were strongly associated with the survival of HIV patients. Conclusions: The study findings revealed that high mortality was observed within the first three months of ART initiation. Patients with poor baseline clinical characteristics had a higher risk of mortality. Expanded testing and counseling should be encouraged, with the goal of ensuring early enrollment into the program followed by the initiation of ART in HIV-infected patients.

Bacillus Calmette-Guerin(BCG) has been widely used for the prophylaxis of superficial bladder tumor recurrence and for the treatment of bladder carcinoma in situ. More than 95% of patients who receive BCG instillation tolerate the treatment well and side reactions have been reported in less than 5% of patients. Most side effects are minor and self-limiting. However, a rare occurrence of severe systemic reactions have been reported. Among the severe systemic reactions, hypersensitivity pneumonitis should be considered in patients with pneumonic complications after BCG instillation in cases where the culture for mycobacteria is negative in the sputwn, brochoalveolar lavage and blood specimen. In addition, a fiberoptic bronchoscopy with transbronchial lung biopsy demonstrates a fibrosis of the alveolar septums, where there is and an increased lymphocyte count with out tuberculous inflammatory changes, the and CD4 : CD8 ratio is increased and no symptomatic response to antituberculosis chemotherapy is observed. Here we report a 68 years old man with interstitial pneumonitis following intravesical BCG instillation.

A 73-year-old man was admitted with a sudden onset of dyspnea. He had never smoked. The chest radiograph and computed tomography revealed bilateral ground glass opacity and an enlarging perihilar consolidation with lymphadenopathies. There was a higher percentage of eosinophils (72%) in the bronchoalveolar lavage fluid (BALF) than normal. The patient was diagnosed with acute eosinophilic pneumonia and managed with steroid. Pneumocystis pneumonia (PCP) was diagnosed by an examination of the BALF, and the patient was treated with trimethoprim-sulphamethoxazole. The patient tested positive to the HIV antibody and the peripheral blood CD-4 positive lymphocyte count was only $33/{\mu}L$. The percentage of eosinophils in the BALF can increase in some cases of PCP that is complicated with AIDS. Only a few cases of eosinophilic pneumonia associated with PCP pneumonia have been reported in patients with AIDS but there are no case reports in Korea. This case highlights the need to consider PCP when the percentage of eosinophils in the BALF is elevated.

연구배경: 폐암은 우리나라 남자들의 악성종양중에서 2번째로 많으며, 수술요법이 가장 좋은 치료이나 대부분의 환자들이 진단당시 수술을 받을 수 없을 정도로 진행되어서 방사선치료(RT)나 항암치료를 동반한 RT를 받게되는데, 방사선-폐렴 및 폐섬유증의 발생이 제일 중요한 부작용이다. 방사선-폐렴은 대개 치료부위에 국한되어 발생하나 때로는 반대쪽에서까지 생기기도하며, Gibson 등은 RT후 양쪽폐에서 BAL액내 세포수 및 임파구가 증가한다고 보고하였다. 방사선-폐렴이 RT의 가장 중요한 제한요소이기 때문에 이의 발생을 조기에 진단하는 것이 환자의 예후에 매우 중요한 영향을 미친다. 이에 연구자들은 염증반응을 야기하는데 중요한 역할을 한다고 알려진 접착분자(ICAM-1, CD18)들이 방사선-폐렴의 발생에도 작용을 하는지, 만일 한다면 이를 방사선-폐렴의 진단 및 예측인자로 사용할 수 있을 가를 살펴보고, 또 방사선-폐렴이 양측성으로 오는 가를 보기위하여 본 연구를 시행하였다. 대상: 조직학적으로 확인된 폐암으로 RT를 받을 환자 29예를 대상으로 하였는데 RT 전에는 16예에서, RT후 1~2개월에는 18예에서 BAL및 혈중 sICAM 농도를 측정하였다. 5예에서는 RT전 및 후에 BAL을 시행하였다. 결과: 7예에서 임상적으로 유의한 방사선-폐렴이 발생하였다. 전 환자군에서 보면, BAL 액내 총 세포수가 $20.2{\pm}10.2{\times}10^6\;cells/L$에서 $35.3{\pm}21.6{\times}10^6\;cells/L$(p=0.0344)로 증가하였으며, 임파구도 $5.3{\pm}4.2%$에서 $39.6{\pm}23.4%$로 유의하게 증가하였다(p=0.0001). 이러한 변화는 RT를 받은 쪽 뿐 아니라 받지 않은 쪽에서도 같이 일어났으며, 방사선-폐렴이 생긴 환자와 생기지 않은 환자 사이에서도 차이가 없었다. 혈중 sICAM농도와 BAL애내 농도는 RT전후로 유의한 차이가 없었으나(혈청: $378{\pm}148$, $411{\pm}150\;ng/ml$, BALF: $20.2{\pm}12.2$, $45.1{\pm}34.8\;ng/ml$) 방사선-폐렴이 발생한 환자들에서는 방사선-폐렴이 생기지 않은 환자에 비해 sICAM 유의하게 증가되었다(혈청: $505{\pm}164$ vs $345{\pm}102\;ng/ml$, p=0.0253, BALF: $67.9{\pm}36.3$ vs $25.2{\pm}17.9\;ng/ml$, p=0.0112). 또한 폐포대식세포(AM)에서의 ICAM-1 발현도도 RT후에 증가하는 추세를 보였으나 통계적 유의성은 없었는데(RMFI: from $1.28{\pm}0.479$ to $1.63{\pm}0.539$, p=0.0605), 방사선-폐렴이 생긴 환자들에서($2.10{\pm}0.390$) 방사선-폐렴이 생기지 않은 환자에 비해($1.28{\pm}0.31$, p=0.0002) 유의하게 높았다. 이상의 BAL 결과로 미루어 RT후에 대부분의 환자들에서 양측성으로 subclinical alveolitis가 발생한 확인하였다. 그러나 임상적인 방사선-폐렴은 훨씬 드물게 발생하고, AM의 ICAM발현도 및 혈중 sICAM농도는 이러한 임상적인 방사선-폐렴발생의 좋은 지표가 될 수 있다고 사료된다.
