  • In order to set the lasing variables and evaluate, clinically, the therapeutic effects of a pulsed Nd:YAG laser on oral lesion, the author applied the laser energy from a fiberoptic delivered, free running, pulsed Nd:YAG laser (wavelength 1064nm, Pulse duration 120$\mu$sec, fiber diameter 200$\mu$m/320$\mu$m) to 22 cases of oral soft tissue lesions and 6 cases of oral hard tissue lesions. The obtained results were as follows : 1. The effective excision with contact mode and the effective hemostasis of accompanied bleeding with noncontact mode were occurred by lasing on oral soft tissue lesions with fiber diameter of 320$\mu$m under the variables of 2.0~4.0W and 20~50Hz which were controlled into high power/low pulses for excision, low power/high pulses for hemostasis, low power in granulation tissue and high power in fibrous tissue according to therapeutic goals and tissue conditions. 2. About 50% of decreasing effect on hypersensitivity was occurred by lasing with non-contact and contact mode on cervical abrasion which caused dentinal hypersensitivity with fiber diameter of 320$\mu$m under the variables of 0.7 - 1.0W and 10Hz which were applied 2~3 times with 1 week interval. 3. The effective sterilization of infected root canal and lesion of periapical abscess was occurred by lasing with contact and spiral modes on wall of root canal and periapical abscess with fiber diameter of 200$\mu$m of which the tip was placed about 1mm shorter than root canal length under the variables of 1.OW and 10Hz.

  • Vitamin E, which has its advocates in the treatment of diabetes mellitus. autoimmune disease, cancer and peripheral vascular and thromboembolic disease, has now been alleged to have a powerful antioxident effect and to affect various biological activities such as fertility factor, inhibition of human platelet aggregation and stabilization of biological membranes. The present study was designed to test whether vitamin I(alpha-tocopherol) can : (1) enhance the hemagglutinin response to sheep red blood cells (SRBC), (2) modulate Arthus and delayed type hypersensitivity(DTH) to SRBC and contact hypersensitivity to dinitrofluorobenzene (DNFB). (3) enhance the mitogenic response of murine splenocyte, (4) decrease the recovery of Cryptococcus neoformans from brain, lung, liver, spleen and kidney of infected mice and (5) have an inhibitory or enhancing effect on the induction of active systemic anaphylaxis(ASA) induced by chicken-gamma globulin (CGG) in mice. Mice were given either intramuscular injections of 0.3ml (300mg) of vitamin I before immunization or were infection for 10 consecutive days or were given by vitamin I esophageal intubation, 0.1ml(100mg), for 20 days before sacrifice for the mitogenic response experiments. It was found that vitamin E treated mice showed a significant enhancement in hemagglutinin response, Arthus reaction and DTH to SRBC and contact hypersensitivity to DNFB. There was no significant difference in the mitogenic response to phytohemagglutinin(PHA), but the response to concanavalin A(ConA) or pokeweed mitogem(PWM) was increased in vitamin E-treated mice. Interestingly, the vitamin E administration before C. neoformans infection decreased significantly the recovery of C. neoformans from brain lung, liver, spleen and kidney of the infected mice as compared with that of the control mice, strongly suggesting that vitamin E pretreatment may increase the resistance of mice to the fungal infection. Unexpectedly, vitamin E administration enhanced the production of CGG -induced ASA. Taken together, it can be concluded that vitamin I administration may in-crease the humoral and cellular immune response and resistance. to C. neoformans infection, but enhance the induction of ASA to CGG. Further studies are necessary to clarify the underlying mechanism accounting for these effects.

  • Exposure of skin to UV-B radiation can cause inflammatory response and immunosuppression. It has been reported that Korean Red Ginseng (KRG) has several pharmacological and physiological effects such as antioxidant, anticancer and improving immune function. In this study, we investigated that topical KRG and KRG + EGb 761 (Ginkgo biloba extract) combination prevented UV-B induced inflammation and inhibition of contact hypersensitivity response. Topical application of KRG, f days prior to or 5 days after exposure to 1MED and 2MED of UV-B, reduced skin thickness compared to non -treated group and resulted in protection against immunosuppression. However, KRG+EGb 761 combination has a little protection against the only 1MED UV-B. In conclusion. Topical application of KRG was more effective than combination in protection against UV-B induced inflammation and immune suppression. Also, we suggest that KRG can provide protection from inflammation and immunosuppression by UV-B radiation.

  • Okbyungpoongsan(OBPS) has long been known to have anti-allergic effect. In order to evaluate the influence on innate and specific immune response, the effects of OBPS on vascular permeability. hypersensitivities and phagocytic functions were measured. As the results, OBPS increased phagocytic activity of peritoneal macrophages in vitro and in vivo. But OBPS depressed formation of reactive oxygen intermediates(ROI) in vitro and in vivo, while the drug enhanced generation macrophages. Foot pad swelling in the mouse and contact hypersensitivity against dinitroflouorobenzene were decreased. OBPS had no effect on NK cells. But OBPS decreased vascular permeability induced by histamine without statistical significance. These results demonstrate that OBPS suppresses hypersensitivity reactions without affecting phagocytic functions and formation of ROI from macrophages. It also means that OBPS acts as a effective inducer to synthesis of nitric oxide which is effective for the infectious disease while it does damage to tissue less as it suppresses ROI, So we can conclude that OBPS could be used for the treatment of the disease related with immune function.

  • Background: Toluene diisocyanate (TDI) can cause contact allergy and occupational asthma, but the mechanism underlying sensitization to this chemical compound remains controversal. Also the correlation of mast cell with contact hypersensitivity (CHS) and the role of mast cell in the TDI-induced CHS is unknown. This issue was investigated by administrating TDI on the skin of genetically mast cell-deficient WBB6F1/$J-Kit^{W}/Kit^{W-v}$ ($W/W^{V}$) and congenic normal WBB6F1/J-Kit+/+ (+/+) mice. Methods: To development of animal model of TDI-induced CHS and to investigate the correlation of mast cell with CHS and the role of mast cell in the TDI-induced CHS, $W/W^V$ and +/+ mice were sensitized with TDI on the back skin at day 1 and day 8, and then challenged with 1% TDI on the ear at day 15. At 1, 2, 4, 8, and 24 hours after 1% TDI challenge, the ear thicknesses were measured. It was investigated the histologic changes of dermis in the ear of $W/W^V$ and +/+ mice at 24 hours after 1% TDI challenge. Results: TDI induced a significant ear swelling response in $W/W^V$ and +/+ mice. TDI induced the significant infiltrations of polymorphonuclear leukocytes and eosinophils in $W/W^V$ and +/+ mice, but not of mast cells in normal mice. And TDI increased a characteristic extent of mast cell degranulation in normal mice. There were no significant differences in the ear swelling and the infiltrations of polymorphonuclear leukocytes and eosinophils of normal versus $W/W^V$ mice, either at baseline or after TDI-induced CHS. Conclusion: From the above results, TDI can be used as a murine CHS model, and the mast cells may not be essential in TDI-induced CHS.
