  • Background: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are immune-complex-mediated hypersensitivity reactions that predominantly involve skin and mucous membranes. Despite the low incidence, both are considered medical emergencies as the mortality rate has been estimated at 30-50%. Although as many as half of cases are idiopathic, several drugs have been implicated as main cause of SJS/TEN. This review therefore aimed to identify drugs that were potentially associated with SJS/TEN and compare the relative risk of the medications. Method: A comprehensive search was performed using MEDLINE, EMBASE and 5 Korean databases. We defined study drugs as non-steroidal anti-inflammatory drugs (NSAIDs), antibiotics, antiepileptics, and allopurinol. Only epidemiologic studies investigating associations between the above drugs and drug-induced SJS/TEN were included. Two reviewers independently selected and evaluated candidate papers and extracted odds ratios or incidence rates. Meta-analysis was performed only for drugs that were reported from 4 or more studies. Results: We found 8 case-control studies, 3 cohort studies and 1 RCT. The ranges of adjusted ORs were 0.6-34.0 for NSAIDs, 1.6-302.0 for antiepileptics, 0.3-10.0 for antibiotics and 1.0-187.0 for allopurinol. The drug with the highest incidence of SJS/TEN was carbamazepine (40 persons/1,000 DDD). Conclusion: Finally, the risk was highest in first 8 weeks after onset of treatment in all drugs.

  • Rituximab (RTX) is a chimeric monoclonal antibody that inhibits CD20-mediated B-cell proliferation and differentiation. Several studies have examined its use in intractable nephrotic syndrome (NS) with some positive results. However, those studies examined such effects for a short-term period of 1 year, and some patients continued to relapse after a lapse in RTX treatment. Our use of RTX as a maintenance therapy (RTX injection when the CD19 cell count exceeded $100-200/{\mu}L$ before relapse) showed some noticeable efficacy. We used RTX in 19 patients with steroid-dependent NS (SDNS). In 12 patients treated with RTX maintenance therapy, only one relapse occurred. The mean treatment period was $23.4{\pm}12.7months$, and the mean number of RTX administrations was $3.9{\pm}1.6$. The relapse rates were decreased (from 2.68/year to 0.04/year), and the drug-free period also increased (from 22.5 days/year to 357.1 days/year) during maintenance therapy. The other seven patients were treated with one cycle of RTX or additional cycles in case of relapse (non-maintenance therapy). Relapse rates were significantly decreased after RTX treatment (from 1.76/year to 0.96/year, P=0.017). The relapse-free period was $15.55{\pm}7.38$ (range, 5.3-30.7) months. No severe side effects of RTX were found except for a hypersensitivity reaction such as fever and chills during its infusion. In conclusion, RTX is considered an effective and safe option to reduce the relapse rate by a single- or maintenance-interval therapy in SDNS.

  • To evaluate the immunomodulatory activity of a water extract (KMF-WE) of Korean mistletoe (Viscum album var. coloratum) fruit, we examined its ability to induce humoral and cellular immune response against keyhole limpet hemocyanine (KLH). Immunized mice with KLH admixed with KMF-WE (KLH/KMF-WE) showed significant induction of KLH-specific antibodies compared to mice immunized with KLH alone. The assay for determining isotypes of antibodies revealed that KMFWE augmented KLH-specific-IgG1 and -IgG2a production. In vitro T lymphocyte proliferation analysis against KLH revealed that the splenocytes of mice immunized with KLH/KMF-WE showed a significantly higher proliferative ability than those from mice immunized with KLH alone. The culture supernatants of splenocytes, which were harvested from mice immunized with KLH/KMF-WE, showed higher levels of both Th-1 type (IL-2, IFN-${\gamma}$) and Th-2 type (IL-4) cytokines in response to KLH stimulation compared to those from mice immunized with KLH alone. Also, in delayed-type hypersensitivity (DTH) assay, mice immunized with KLH/KMF-WE showed a significantly higher reaction to KLH than mice treated with KLH alone. These results suggest that KMF-WE possess immunoadjuvant activity to enhance both antigen-specific humoral and cellular immune responses against protein antigens (KLH).

  • This review summarizes gender differences in pharmacokinetics, pharmacodynamics, and adverse drug reactions. Gender differences in pharmacokinetics are categorized by four major factors: absorption/bioavailability, distribution, metabolism, and elimination. There are sex-based differences in gastric emptying time, gastric alcohol dehydrogenase activity, apparent volume of distribution, ${\alpha}1$-acid glycoprotein level, phase I (CYP) and phase II metabolizing enzymes, glomerular filtration rate, and drug transporters. This review also reports gender differences in pharmacokinetics and pharmacodynamics of cardiovascular agents, central nervous system acting agents and antiviral agents. In addition, it has been reported that females experience more adverse reactions such as coughing, tachycardia, nausea, vomiting, rash, hypersensitivity, hepatotoxicity, and metabolic disorder after taking cardiovascular, central nervous system acting and antiviral agents. Therefore, in order to provide optimal drug dosage regimens both in male and female, gender differences in pharmacokinetics, pharmacodynamics, and adverse drug reactions must be considered.

  • This study was carried out to know the effects of sopunghwalhyeoltang-gamibang(hereinafter referred to SPHHT) on the inhibition of arthritis induced by collagen on the mouse. Various experimental were performed in vivo (in DBA/1 J mice which are experimental model of arthritis induced by collagen) to analyse the immunomodulatory effects of SPHHT. The results were obtained as follows: 1. The cytotoxicity against mLFC was not measured in all concentration. 2. The arthritis index, incidence, hind paw edema, delayed-type hypersensitivity reaction, spleen weight were reduced in SPHHT treated group. 3. The expression of CD3 ε +/CD4+, CD3 ε +/CD8+ and CD19+ in peripheral blood mononuclear were reduced in SPHHT treated group. 4. The production of pro-inflammatory cytokines such as IL-6 and TNF-α were significantly reduced in SPHHT treated group. 5. The formation of new bones and synivium were stimulated in SPHHT treated group. Comparison of the results for this study showed that Sopung-hwalhyeoltang-gamibang had immunomodulatory effects. So we expect that Sopunghwalhyeoltang-gamibang should be used as a effective drugs for not only rheumatoid arthritis but also another auto-immune disease. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.

  • To observe the effect of Demodex canis infection on the cellular immune response and hematological profile, 8 Doberman pinschers experimentally infected with D cains and 4 uninfected control dogs were sensitized with 2, 4-dinitro-chlorobenzene(DNCB) on the skin and were challenged with DNCB 14 days after the initial sensitization to elicit allergic contact dermatitis. Histological and hematological changes of these dogs were then observed. Macroscopic changes of skin challenged with DNCB in D canis-infected dogs included significantly reduced area of allergic reaction(p<0.05) than in uninfected control group. Infiltration of inflammatory cells in the D canis-infected group was also significantly reduced(p<0.05) than in the uninfected control group. These changes indicated that the cell-mediated immune response of the animals was suppressed by the infection with D canis. Total white blood cell count in dogs infected with D canis was increased when dogs were sensitized with DNCB (p<0.01). The result appeared to be caused by stress due to D canis infection, secondary bacterial infection and decreased efficacy of general body defense system. Blood eosionophils were increased in D canis-infected dogs which appreared to be caused by the allergic contact dermatitis. Blood chemistry analysis revealed that total protein and globulin were increased(p<0.05), while albumin level was decreased. This result appeared to be caused by secondary bacterial infection.

  • Purpose: Traditionally, titanium miniplate has been used for rigid fixation of mandible fractures. However, the limitations of metal plate have been reported such as hypersensitivity, interference with the cranio-facial growth of growing child, secondary bone resorption around the plate, foreign body reaction, declination of primary callus formation, and bone atrophy, and so forth. Recently, biodegradable miniplate has been introduced and used as an alternative to the metal plate despite of its lower strength. This study evaluated the usefulness and stability of biodegradable plate and screw for treatment of mandible fractures. Methods: In this study, 61 patients(92 areas) diagnosed as mandible fracture in the last 2 years have been reviewed. We used titanium plate and screw in 32 patients, and biodegradable plate and screw($INION^{(R)}$) in 29 patients. Stability of plates and screws, bony healing process and its side effects were observed by clinical and radiographic assessment. Results: In the titanium material group, one of malocclusion, two of mouth opening limitation, three of pain, three of palpation were shown. The plate of six patients involved in these complications were removed. In the biodegradable group, two of mouth opening limitation, two of pain, one of localized wound infection were shown and one plate was removed secondarily. Conclusion: There was no statistical difference between two groups in bony healing and complication rates. Biodegradable implants show efficient stability during initial bone healing and low side effects in long-term follow up periods.

  • The root of Bupleurum falcatum L.(BF) has been widely used in oriental medicine as a major camponent in many prescriptions for chronic hepatitis, renal disease, tuberculosis and some other infectious diseases. Many attempts have done to investigate the therapeutic effects of these principles. However, any kinds of screenig on immune regulatory- and antitumor- effects of BF has not been reported. The present study, therefore, was undertaken to investigate the BF-effects on cellular- and humoral-immune responses, phagocytic activities of macrophages, lymphokine- and Immunoglobulin(Ig)-production of lymphocytes, tumorigenesis of implanted sarcoma 180 cells and B16 melanoma cells, and proliferations of some tumor cell lines(Fsa II, 3LL and EL4). BF increased phagocytic activities of mouse peritoneal macrophages in a dose- and time-dependent fashion. Arthus reaction and antibody responses to SRBC were slightly enhanced but delayed hypersensitivity was depresed when BF was injected before- and after-SRBC sensitization. BF inhibited the proliferative responses of human tonsillar lymphocytes to PHA- and Con A-stimulation but slightly augmented the response of these cells to Staphylococcus aureus Cowan 1(SAC)-activation. Ig secretion of human mononuclear cells activated with SAC was slightly increased by BF. BF significantly augmented the SAC-induced IL 6 production of human mononuclear cells but not influenced Con Ainduced IL 2 secretion. NK cell activities of mouse splenocytes were somewhat increased when BF was pretreated and this responses were due to the increment of binding affinities of effector cells to target cells and of lytic activities of effector cells against target cells. In vitro BF significantly inhibited the proliferations of cancer cells such as Fsa II, 3LL and EL4 strains. BF decreased not only the frequency of tumor induction but also the tumor size per sarcoma 180 or B16 cell-implanted mouse. Taken together, these results indicate that BF is one of the potential immunomodulator, and suggest its possibility to be used as a desirable antitumor agent.

  • It was claimed that the herbal medicine with the function of strengthening the body resistance exerts to enhance the immunity. And the medicine with the effect of eliminating the pathogenic factor is stated to inhibit the immune response. To evaluate the the effects of the herbal medicine on the immune response, the mice were administrated with the herbal medicine for 2 weeks. And the responses were analyzed. As the result, water extract of Radix Astragali, Fructus Psoraleae, Cortex Acanthopanacis, Semen Coicis, Herba Ecliptae, Spica Prunellae, and Radix Sophorae increased the ROI production, while Radix Tripterygia inhibited it. Phagocytic activity was increased after administration of Radix Astragal, Fructus Psoraleae, Cortex Acanthopanacis, Herba Ecliptae, Spica Prunellae and Radix Sophorae. NK cell activity was also significantly inhibited by Radix Tripterygia. Administration of Radix Astragali, Fructus Psoraleae, Cortex Acanthopanacis, Herba Ecliptae, Spica Prunellae and Semen Coicis enhanced the antibodies(hemagglutinin and hemolysin) formation and the appearance of rosette forming cells of the spleen, while Radix Sophorae and Radix Tripterygia decreased it. Radix Sophorae and Radix Tripterygia also decreased the allogenic immune response and mixed-lymphocyte reaction. And all the experimental herbs decreased contact hypersensitivity against dinitroflurobenzene. These results show Radix Astragali, Fructus Psoraleae, Spica Prunellae, Cortex Acanthopanacis, Semen Coicis and Herba Ecliptae enhanced innate immunity, humoral and cellular immune responses. However Radix Sophorae and Radix Tripterygia exert imunosuppressive action. Also these results indicate that the medicine with the action of the strengthening the body resistance enhances the immunity. And the the some of drugs belonging to the eliminating the pathogenic factor also increase the immune responses.
