In the present study, whether squalene treatment relives inflammatory reactions induced by Candida albicans was checked. The experiment was conducted in vivo using seven experimental animals (ICR mice) per experimental group. Among C. albicans-induced inflammatory factors, TNF-${\alpha}$, IL-6, and NO were observed using the ELISA kits method. Through the experiment, the following conclusions were obtained. 1. In the group infected with C. albicans, it could be identified that squalene treatment was inducing NO generation in renal tissues both on the 1st and 3rd days (p < 0.05). 2. In the group pre-treated(intraperitoneal administration) with SQ (80ml/kg) once per day for seven days and infected with C. albicans, it could be identified that squalene treatment was inducing TNF-${\alpha}$ generation in renal tissues only on the 3rd day(p < 0.05). 3. In the group pre-treated(intraperitoneal administration) with SQ (80ml/kg) once per day for seven days and infected with C. albicans, it could be identified that squalene treatment was inducing IL-6 generation in renal tissues only on the 3rd day(p < 0.05). In conclusion, it could be seen that for squalene to suppress C. albicans-induced inflammatory factors, preemptively supplying SQ should be effective. Therefore, effects for recovery from C. albicans-induced immunodepression can be expected from SQ treatment.

Background: Ginseng (G) and Ligustrum lucidum Ait (LLA) are core traditional Chinese medicines in treating myelosuppression formula. The present study was designed to profile effect of G and LLA herb pair (G-LLA) on myelosuppressed mice. Methods: The mice myelosuppression model was established by intraperitoneal (i.p.) injection of cyclophosphamide (Cy). Hematopoietic function of bone marrow was measured by hemopoietic progenitor cell culture and peripheral blood count, and serum hemopoietic factors were tested by enzyme-linked immunosorbent assay. Bone marrow cell cycle was performed by flow cytometry. HPLC was used to measure 20 potential chemical components related to myelosuppression, including ginsenoside Rg₁, Re, Rb₁, Rc, Rb₂, Rb₃, Rd, Rk₃, Rh₄, 20 (S)-Rg₃, 20 (R)-Rg₃, Rk₁, Rg₅, salidroside, and so on. Results: G, LLA, and G-LLA improved the amount of peripheral blood cells and bone marrow cells of myelosuppressed mice (P < 0.01). They significantly increased the colony quantity of colony-forming unit-granulocyte macrophage, burst-forming unit-erythroid, colony-forming unit-erythroid, and colony-forming unit-megakaryocyte and amount of G₂/M and S phase cells (P < 0.01). They also significantly decreased the amount of hematopoiesis-related cytokines (P < 0.01). The content of chemical components in G-LLA changed, and the change of rare saponin was the most obvious. Conclusion: These results show that G-LLA herb pair might produce synergistic or complementary compatibility effects on bone marrow suppression after chemotherapy. It suggests that the substance basis of G-LLA for treating bone marrow suppression may be effective chemical components.

Hantaan virus(HV) 76-118 strain was inoculated into suckling ICR mice by intra-nasal route with an inoculum of $10LD_{50}$. Mortality was 65% at the 3rd week after inoculation, but declined to 35% at the 4th week. Infectivity was determined by the measuring immuno-fluorescent antibody in sera. The peak of infectivity was 80% at the 4'th week after inoculation. Viremia was reached peak level of $1.7{\times}10^4\;PFU/ml$ by day 10. Immunofluorescent antibody and neutralizing antibody appeared by 2 weeks and 15-17 days respectively, but achieved similar titer by 35 days. By using a monoclonal antibody to HV 76-118, viral antigens were initially detected in inguinal and axillary lymph node by 2 days. Viral antigens in bone marrow and lung were delayed much more than in those of lymph node. These were similar with those of intra-peritoneal and intra-muscular route. Immune complex against IgG, IgM and C3 appeared by 16 days, 14 days, and 18 days respectively. The pattern of immunofluorescence in the basement membrane of glomeruli was diffuse membranous. Spotted pattern was also observed in the tissue stained with anti-mouse C3 antibody. By 20 days, control tissue was also shown immune complex in the glomeruli.

The purpose of this research was to investigate the anti-inflammatory effects of Yongdamsagantanghaphwangryunhaedogkagam(YSHHK) which has been medicated the patient such as breast cellulitis. YSHHK did not show any cytotoxic effect on mouse lung fibroblast cells at any of the concentrations evaluated(200, 100, 50, 10, 1 ${\mu}g/m{\ell}$). YSHHK in RAW264.7 cell inhibited $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, COX-2 and NOS-II mRNA genes expression in a concentration-dependent manner. YSHHK inhibited NO production significantly at the concentration of 100, 50 ${\mu}g/m{\ell}$ and ROS production in a concentration-dependent manner. YSHHK inhibited $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production significantly in serum of mice with LPS-induced acute inflammation. YSHHK increased survival rate of mice with LPS-induced lethal endotoxemia, compared to the control group, from the 3rd day onward. These results suggest that Yongdamsagantanghaphwangryunhaedogkagam(YSHHK) can be useful in treating mammary diseases caused by inflammation such as breast cellulitis.

Five ginsenosides $(A_1,\;A_2,\;B_1,\;B_2,\;C)$ and a yellow pigment were isolated from American ginseng stems and leaves. Ginsenoside $A_2,\;B_1,\;B_2$ and C were proven to be identical with Korean ginseng root ginsenoside $Rg_1,$ Rd, Re and $Rb_2,$ respectively. The yellow pigment proved identical with panasenoside isolated from Korean ginseng leaves. Ginsenoside $A_1$, which was also present in American ginseng roots, was not identical to any of the known root (ginsenoside $R_{0}-Rg_{2}$) and leaf (ginsenoside $F_{1}-F_{3}$) Korean ginseng saponins. A gas-liquid chromatographic method was developed to analyze ginsenosides and sapogenins in rabbit plasma and urine samples. Panasenoside and stigmasterol were found to be the best internal standards for ginsenosides and sapogenihs, respectively. Ginsenoside C had a significantly longer half-life, higher plasma protein binding, lower metabolic and renal clearance than ginsenoside $A_1,\;A_2\;and\;B_2$. Ginsenosides were not found in rabbit plasma and urine samples after oral administration. Ginsenoside C had a higher toxicity than ginsenoside $A_2$ after intraperitoneal administration to mice. Toxicity was not observed after oral administration of the ginsenosides.

The studies were conducted to investigate the combined effects of Tonics and Mitomycin C(MMC). The effects of Tonics and MMC on the proliferation of Molt-4 cells, human leukemic cell line, and activation of human lymphocytes were estimated by MTT colorimetric assays. Selected medicines among 9 kinds of Tonics by results of MTT assays were treated with MMC in mice. The Tonics itself enhanced the proliferation of Molt-4, but the anti-proliferative effect of MMC was not intercalated by the combined treatment of Tonic and MMC. Inhibitory action of MMC was augmented by Sa Kun Ja Tang(SKT). This result was due to the inhibition of DNA synthesis. Among 9 kinds of Tonics, Sip Jean Dae Bo Tang(SDT), Saeng Maek San(SMS) and Kwi Bi Tang(KBT) did not inhibit the action of MMC, but activated lymphocytes. When the mice were treated by MMC, the number of leukocytes was decreased significantly at the 1st day, but recovered at the 7th day. In the groups of MMC treated with SDT or KBT, the number of leukocytes was increased significantly than the group of MMC treated only at the 3rd day. Combined treatment of the Tonics(SDT, SMS) and MMC retained the body weight of mice at the level of normal mice. SDT, SMS and KBT did not change the number of plaque forming cells(PFC), but MMC treated group decreased the number of PFC. The combined treatment of MMC and SDT increased the number of PFC significantly than the MMC treated group. SDT, SMS and KBT did not influence the proliferation of T cells, but MMC treated group decreased the proliferation of T cells. The combined treatment of MMC and those tonics increased the T cell proliferation significantly than the MMC treated group. In conclusion, the results presented in this paper suggest that SDT, SMS and KBT can recover the side effects of MMC, such as weight loss, leukopenia and immunosuppresion, without any intercalating the anti-proliferative action of MMC in vivo.

Retinal prostheses have shown some clinical success in restoring vision in patients with retinitis pigmentosa. However, the post-implantation visual acuity does not exceed that of legal blindness. The reason for the poor visual acuity might be that (1) degenerate retinal ganglion cells (RGCs) are less responsive to electrical stimulation than normal RGCs, and (2) electrically-evoked RGC spikes show a more widespread not focal response. The single-biphasic pulse electrical stimulation, commonly used in artificial vision, has limitations in addressing these issues. In this study, we propose the benefit of multiple consecutive-biphasic pulse stimulation. We used C57BL/6J mice and C3H/HeJ (rd1) mice for the normal retina and retinal degeneration model. An 8 × 8 multi-electrode array was used to record electrically-evoked RGC spikes. We compared RGC responses when increasing the amplitude of a single biphasic pulse versus increasing the number of consecutive biphasic pulses at the same stimulus charge. Increasing the amplitude of a single biphasic pulse induced more RGC spike firing while the spatial resolution of RGC populations decreased. For multiple consecutive-biphasic pulse stimulation, RGC firing increased as the number of pulses increased, and the spatial resolution of RGC populations was well preserved even up to 5 pulses. Multiple consecutive-biphasic pulse stimulation using two or three pulses in degenerate retinas induced as much RGC spike firing as in normal retinas. These findings suggest that the newly proposed multiple consecutive-biphasic pulse stimulation can improve the visual acuity in prosthesis-implanted patients.

The aerial parts of Gomphocarpus sinaicus Boiss. yielded four flavonoids that were identified as isorhamnetin 3-O-rhamnoglucoside (1), luteolin-7-O-glucoside-3-O-rhamnoside (2), rutin (3) and rutin-7-O-rhamnoside (4). All of the isolated flavonoids were identified by spectroscopic methods (UV, FAB-MS, $^1H-NMR\;&\;^{13}C-NMR$) and in comparison with the literature data. The isolated flavonoids 1, 2 and 4 are reported here for the first time from Gomphocarpus sinaicus Boiss. Three sets of experiments were carried out using the defatted alcoholic extract of Gomphocarpus sinaicus Boiss: the $1^{st}$ experiment indicated that the $LD_{50}$ was 49.82 mg/100 g b.wt. of intraperitoneally (i.p.) injected mice. The toxic signs were recorded within the first 24 hr post-injection. The $2^{nd}$ experiment revealed that the extract of the plant exhibited significant anti-inflammatory effects in normal rats. The $3^{rd}$ experiment was found that the tested doses of the extract in diabetic rats induced a significant decrease in serum glucose, AST, ALT, triglycerides, cholesterol and LDL, while HDL caused a significant increase.

The studies reported here were undertaken to investigate the effects of mercury chloride on immune system of Balb/c mouse employing a flexible tier of in vitro and in vivo assays. Mercury chloride inhibited the proliferative responses of spleen cells to lipopolysaccharide, pokeweed mitogen, and phytohemagglutinin as a dose-dependent manner. This inhibitory effect was observed not only when $HgCl_2$ was added 2nd or 3rd day of 3 days culture period but also when spleen cells was pretreated with $HgCl_2$ for 2 hours. Mercury chloride, however, potentiated the production of IgM and IgG from spleen cells. During the $HgCl_2$ administration by drinking for 3 weeks, the weight gain of mice was significantly blunted than that o control group mice, while no overt signs related to mercury toxicity were noted in any mice of experimental group. There was no change in thymus and spleen weights, and in histological findings of kidney, bone marrow of femur, thymus, spleen, and popliteal lymph node after 3 weeks of mercury exposure. However, $HgCl_2$ induced a significant increase of total serum IgM, IgG including $IgG_1,\;IgG_{2a}\;and\;IgG_{2b}$, and IgE in Balb/c mice. Treatment in vivo with anti-IL-4 monoclonal antibody significantly abrogated the $HgCl_2$-induced increase in total serum IgG1 and IgE. Whereas $HgCl_2$ potentiated total serum IgM and IgG, there was no difference in total serum hemagglutinin to SRBC (Sheep Red Blood Cell) between experimental and control group mice when these mice were immunized with SRBC. All these findings observed in Balb/c mice suggest that mercury perturbates well-orchestrated regulation of immune responses before developing histopathological changes in lymphoid tissues.

Objectives : To investigate the effect of Ga-mee-Gwui-ryong-tang herbal acupuncture(GR-HA) at GB39 and ST36 and the effect of Yuk-mee-ji-hwang-tang herbal acupuncture(YM-HA) at GB39 and KI10 on growth in mice. Methods : Mice were divided into 7 group(n=10) ; saline-ST36, saline-GB39 and KI10, GR-HA-ST36 group treated with GR-HA at right ST36, GR-HA-GB39 group treated with GR-HA at right GB39, YM-HA-GB39 group treated with YM-HA at right GB39, YM-HA-KI10 group treated with YM-HA at right KI10. Saline-ST36 group, saline-GB39 group and saline-KI10 group were injected with saline at right ST36, GB39, KI10 respectively. Saline injection and HA were performed 3 times a week for 18 days. The length(total height, body length and tail length), weight and the protein efficiency ratio were measured as well as IGF-1 level in serum. Results : 1. GR-HA at GB39 and GR-HA at ST36 promoted growth in weight, tail length and total height but there was no statistical significance. 2. GR-HA at GB39 significantly promoted protein efficiency on the 14th day and GR-HA at ST36 on the 3rd day. 3. GR-HA at GB39 significantly increased serum IGF-1. GR-HA at ST36 increased IGF-1 slightly but with no statistical significance. 4. YM-HA at GB39 and YM-HA at KI10 promoted growth in weight, height, tail length and total height but there was no statistical relevance. 5. YM-HA at GB39 and YM-HA at KI10 significantly promoted protein efficiency on the 14th day. 6. YM-HA at GB39 and YM-HA at KI10 significantly increased serum IGF-1. Serum IGF-1 level of YM-HA-KI10 group was significantly higher than that of YM-HA-GB39 group. 7. Serum IGF-1 level of GR-HA-GB39 group was significantly higher than that of YM-HA-GB39 group. Conclusions : GR-HA and YM-HA both may promote growth. This study suggests that herbal acupuncture at GB39 is more effective with Gwui-ryong-tang than Yuk-mee ji-hwang-tang to promote growth. It also suggests that Yuk-mee ji-hwang-tang herbal acupuncture is more effective at KI10 than at GB39.
