Several studies showed that the immunological factors such as CD4+ cell number, CD4%, CD8+ cell number and CD4/CD8 ratio and the serological factors such as, ${\beta}^2$-microglobulin(${\beta}^2$-MG), neopterin, soluble CD4, and soluble CD8 are related to the risk of development of AIDS. Especially, the CD4+ cell counts have been used to monitor progresson of HIV disease, to stratify, and to follow patients in clinical trials. Recently, the Centers for Disease Control and Prevention(CDCP) in USA has made the CD4+ cell count as a part of the classification of HIV disease. It is composed of 3 categories such as 1, 2, and 3 which asr $\geq$ 500/$mm^3$, 200/$mm^{3} $\geq$ and < 500/$mm^3$, and < 200/$mm^3$, respectively. In this study, to estimate the differences of immunological factors between HIV-infected and normal human groups in Korea, CD4+ T and CD8+ T cells, and the CD4/CD8 ratio were measured in 185 HIV-infected subjects and 140 healthy adult subjects. The lymphocyte subsets such as CD4+ T and CD8+ T were analysed by flow cytometer(FACStar) with two-color immunofluorescent stain using monoclonal antibodies such as anti-CD4 and anti-CD8 antibodies. The absolute numbers and percentages of CD4+ T and CD8+ T and the CD4/CD8 ratio of HIV infected persons were $462\pm{277}/mm^3$, $18.2\pm7.7%$, $1,170\pm{534}/mm^3$, $47.0\pm10.6%$ and $0,43\pm0.26 whereas those of uninfected persons were $886\pm{299}mm^3$, $32.9\pm{7.0%}, 730{\pm}259/mm^3$, $26.8\pm6.4%$ and $1.31\pm0.46$(P<0.01). In addition, estimating the reference values of peripheral blood lymphocyte subsets of Korean, the absolute numbers and percentages of CD4+ T and CD8+ T and the CD4/CD8 ratio of 140 healthy adults persons were measured and compared with those of foreigners. The reference ranges of CD4+ T cells, CD8+ T cells, CD4％, CD8%, and the CD4/CD8 ratio and 1.31$\pm$0.46, respectively. The significant differences were not observed when compared with those of foreigners. However a little difference was observed in the percentages of CD4+ T and the absolute numbers of CD8+ T between the normal values of Korean and those of foreigners were $43.6\pm8.9%$, $560\pm{230}/mm^3$. This result can also be useful as a basic data for the treatment and surveillance of HIV-infected patients in Korea.

Breast cancer is the most common cancer among the population as a whole and among females, yet it is highly curable if diagnosed at an early stage. Different methods are used to diagnose breast cancer. One of these methods features immunological tests using flow cytometry to determine T-lymphocyte (CD4/CD8) ratios in peripheral blood. One hundred patients with breast cancer (50 from Basra, Iraq, and 50 from Baku, Azerbaijan) confirmed to have breast cancer by histopathology were studied. Blood samples were collected from all patients before initiation of treatment and were used for analysis. The mean age of women from Basra was $51.2{\pm}10.7years$ and that of women from Baku was slightly higher at $54.8{\pm}12.2$. The mean CD4/CD8 ratio in Basra was 1.4 and in Baku was 1.8 with P value < 0.05. The percentage of Basra patients who have CD4/CD8 value less than 1 was 50%, while the percentage for Baku patients was 24 % (p < 0.05). While the CD4/CD8 T-lymphocyte ratio might be useful for early diagnosis in patients with breast cancer parallel with other confirmed tests factors involved in explaining variation between countries such as that observed here need to be taken into account.

Objectives: The objective of this study was to investigate the presence of oral lesions in human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients in a descriptive cross-sectional study, and to establish their presence according to levels of CD4+ cells (including the CD4+/CD8+ cell ratio). Materials and Methods: A total of 75 patients infected with HIV were included. Oral lesions were observed and classified using World Health Organization classification guidelines. Potential correlations between the presence and severity of oral lesions and CD4+ cells, including the CD4+/CD8+ cell ratio, were studied. Results: The most frequent oral lesion detected was oral pseudomembranous candidiasis (80.0%), followed by periodontal disease (40.0%), herpetic lesions (16.0%), hairy leukoplakia (16.0%), gingivitis (20.0%), oral ulceration (12.0%), Kaposi's sarcoma (8.0%), and non-Hodgkin's lymphoma (4.0%). The CD4+ count was <$200cells/mm^3$ in 45 cases (60.0%), between $200-500cells/mm^3$ in 18 cases (24.0%), and >$500cells/mm^3$ in 12 cases (16.0%). The mean CD4+ count was $182.18cells/mm^3$. The mean ratio of CD4+/CD8+ cells was 0.26. All patients showed at least one oral manifestation. Conclusion: There was no correlation between the CD4+/CD8+ cell ratio and the presence of oral lesions. The severity of the lesions was more pronounced when the CD4+ cell count was less than $200cells/mm^3$.

To evaluate whether there is a relation between Korean red ginseng (KRG)-intake and the suppression of immune hyperactivation in HIV-1-infected patients, we measured serum soluble CD8 (sCD8) over 31-48 months in 168 patients. They were divided into four groups; HIV-1-infected control (n = 49), zidovudine (ZDV) group (n = 22), KRG group (n = 48), and combination of KRG and ZDV group (n = 49). In control, sCD8 and the ratio of sCD8/CD8+ T cells significantly increased by 33% (paired t-test, P < 0.05) and 54% over $21\;{\pm}\;13$ months (P < 0.001), respectively. In ZDV group, sCD8 decreased within first 6 months and then showed steady increase and the ratio also increased over $19\;{\pm}\;10$ months. In KRG group, sCD8 and the ratio of sCD/CD8+ T cells continuously decreased by 45% (P < 0.01) and 19% over $19\;{\pm}\;11$ months (P < 0.05), respectively. In combination group, sCD8 gradually decreased by 29% (P < 0.01). There was a clear difference in the changes in serum sCD8 over time among 4 groups. There was no rebound phenomenon in KRG group as shown in ZDV group. These results suggest that KRG-intake suppresses immune hyperactivation state by HIV antigen itself in the HIV-infected patients.

Background : Asthma is a chronic inflammatory disorder under immunological influence. Shinbi-tang and Gamishinbi-tang are herbal decoctions used for treating asthma in traditional herbal medicine. Objective : To evaluate the effects of Shinbi-tang and Gamishinbi-tang on immune cell & serum OA-specific IgE in broncho-alveolar lavage fluid (BALF) in rat asthma model. Material and Methods : Rats were sensitized with ovalbumin (OA); at day 1 sensitized group and Shinbi-tang and Gamishinbi-tang groups were systemically immunized by subcutaneous injection of 1mg OA and 300mg of Al(OH)$_3$ in a total volume of 2ml. At the same time, 1 ml of 0.9% saline containing 6 x 10$^{9}$ B. pertussis bacilli was injected by i.p. 14 days after the systemic immunization, rats received local immunization by inhaling 0.9% saline aerosol containing 2%(wt/vol) OA. A day after local immunization, HAL fluid was collected from the rats. Rats were orally administered with each of Shinbi-tang and Gamishinbi-tang extract for 14 days from the day after local immunization. Lymphocyte, CD4+ T cell CD8+ T cell counts, CD4+/CD8+ ratio in BALF, change of serum OA-specific IgE level, CD4+ T cell CD8+ T cell percentages in the peripheral blood were measured and evaluated. Results : Shinbi-tang and Gamishinbi-tang showed an alleviating effect on asthmatic responses of rats. Shinbi-tang decreased total cell, lymphocyte, CD4+ T cell in BALF, serum OA-specific IgE level as compared with the control group. Gamishinbi-tang decreased total cell, lymphocyte, CD4+ T cell, and CD4+/CD8+ ratio in HALF as compared with the control group. CD4+/CD8+ ratio in HALF from Shinbi-tang group and serum OA-specific IgE level from Gamishinbi-tang group didn't show any significant variation from control group. CD8+ T cell in HALF, CD3+CD4+ T cell and CD3+CD8+ T cell percentages in peripheral blood showed no significant variation among groups. Conclusion : Shinbi-tang and Gamishinbi-tang alleviated asthmatic hypen-eactivity of the rat immune system through CD4+ T cell and serum IgE. Further the study of immune system modulating mechanism is expected.

Objectives : To investigate the effects of herb-acupunctures of Qi tonification herbs or formula on the rat immune depression induced by an anticancer drug, methotrexate (MTX) Methods: Animals were divided into 5 groups; Normal control group was not given any treatment. Immune depression was induced by oral administration of 1mg/kg MTX b.i.d for 4 days in Control, Sample I, II, and III groups. We treated on CV 4 (Guanyuan) with saline, Bojoongiggi-tang (Buzhongyiqi-tang), Ginseng Radix and Astragali Radix herb-acupunctures in Control, Sample I, II, and Ill groups, respectively. In both blood and spleen, the assessment of CD4+ T-cell count, CD8+ T-cell count, CD4/CD8 T-cell ratio was performed. Results: Here we show that 3 herb- acupuncture groups have an influence, to some extent, on CD4+ and CD8+ T-cell counts and CD4/CD8 T-cell ratio in both blood and spleen. Astragali Radix herb-acupuncture, in particular, was found to have significantly increased CD4+ T-cell count in blood and CD4/CD8 T-cell ratio in blood and spleen. Conclusions: The results of this study suggest that herb-acupunctures of Bojoongiggi-tang (Buzhongyiqi-tang), Ginseng Radix and Astragali Radix may have an influence over rat immune depression induced by MTX.

Objectives : This study was performed to investigate the effects of Gamichangbaek-san(Jiaweichangbai-san) on anti-inflammatory, analgesic, anti-febrile and immune response on the arthritis of carrageenan-induced animals. Methods and Materials : Rats were classified into control and sample groups which are 7 individuals each for the experiments about anti-inflammatory and anti-febrile. Each of the 7 mice were classified into normal, control, sample groups for the analgesic experiments. Gamichangbai-san(Jiaweichangbai-san) was administered to sample group and normal saline was administered to normal and control groups. Arthritis was induced by injection of 1% carrageenan $0.1m{\ell}$ and Gamichangbaek-san(Jiaweichangbai-san) was administered after 30 minutes. The change of edema in Carrageenan-induced Arthritic Rats' Paws was measured after 1 hour and 5 hours from the injection of carraqeenan with Plethysmometer(7150, UGO BASILE, ltaly) by Winter' method. WBC, Lymphocyte and ESR were measured by heart puncture and CD4+ T cell, CD8+ T cell and CD4+/CD8+ T cell ratio were measured from the spleen tissue. Writhing syndrom was measured with Tail flick unit(UGO BASILE, Italy) in the experiments conducted to check the analgesic activity. The temperature of the paws of carrageenan-induced arthritic rats was measured by Laser thermometer. Rectal temperature was measured by Yeast's method in anti-febrile experiments. Immune response was measured by CD4+, CD8+ T cell ratio and CD4+/CD8+ T cell ratio. Results : 1. It was recognized that Gamichangbaek-san(Jiaweichangbai-san) decreased the increase rate of Paw Edema effectively with statistical significance. 2. It was recognized that Gamichangbaek-san(Jiaweichangbai-san) decreased WBC, Lymphocyte and ESR with statistically high significance. 3. It was recognized that Gamichangbaek-san(Jiaweichangbai-san) did not show significant analgesic effect, but the Pressure pain threshold of the paws was increased with statistical significance. 4. It was recognized that Gamichangbaek-san(Jiaweichangbai-san) decreased rectal temperature effectively and had an anti-febrile effect about the febrile of a joint with statistical significance. 5. It was recognized that Gamichangbaek-san(Jiaweichangbai-san) increased CD4+ T cell ratio with statistically high significance and increased CD+8 T cell ratio with statistical non significance but increased CD4+/CD8+ T cell ratio effectively with statistical significance, too. Conclusions : According to the above results, it can be concluded Gamichangbaek-san(Jiaweichangbai-san) showed the treatment effects on the artificial arthritis resulted from carageenan in rats and it is suggested that more interest and study in the security for the clinical use were needed.
