PZA에 의한 독성 간염은 약 2% 정도 보고되고 있으나 전격성 간염으로 진행하여 사망하는 경우는 드물게 보고되고 있다. 본 증례에서는 항결핵제에 의해 중증 독성 간염을 보였다가 회복된 후 저용량의 PZA을 재투여 하고 전격성 간염으로 진행하는 양상을 보였다. 이번 사례를 통해 저용량의 PZA를 투약시 전격성 간부전으로 진행하는 경우를 경험했고 항결핵제 투여시 면밀한 관찰이 필요하고 항결핵 약제 투여시 신중을 기울여야겠다.

Background: Respiratory syncytial virus (RSV) is a major cause of severe lower respiratory tract diseases in infancy and early childhood. Despite its importance as a pathogen, there is no licensed vaccine against RSV yet. The attachment glycoprotein (G) of RSV is a potentially important target for protective antiviral immune responses. Recombinant baculovirus has been recently emerged as a new vaccine vector, since it has intrinsic immunostimulatory properties and good bio-safety profile. Methods: We have constructed a recombinant baculovirus-based RSV vaccine, Bac-RSV/G, displaying G glycoprotein, and evaluated immunogenicity and protective efficacy by intranasal immunization of BALB/c mice with Bac-RSV/G. Results: Bac-RSV/G efficiently provides protective immunity against RSV challenge. Strong serum IgG and mucosal IgA responses were induced by intranasal immunization with Bac-RSV/G. In addition to humoral immunity, G-specific Th17- as well as Th1-type T-cell responses were detected in the lungs of Bac-RSV/G-immune mice upon RSV challenge. Neither lung eosinophilia nor vaccine-induced weight loss was observed upon Bac-RSV/G immunization and subsequent RSV infection. Conclusion: Our data demonstrate that intranasal administration of baculovirus-based Bac-RSV/G vaccine is efficient for the induction of protection against RSV and represents a promising prophylactic vaccination regimen.

The effects of gastric acidity on the bioavailability of scopolamine hydrobromide and ${\ell}$-hyoscya-mine were studied in rabbits. Each drug was administered orally at dose of 0.2mg/kg to gastric acidity controlled rabbits. The plasma concentration of scopolamine and ${\ell}$-hyoscyamine were determined by selected ion monitoring in GC/MSCScopolamine; m/Z= 138, ${\ell}$-Hyoscyamine; m/z= 124). Rabbits with hypoacidity showed significantly higher Cp and AVC than rabbits with hyperacidity after oral administration of each drug. From the results of this experiment, it is desirable that dosage regimen of dose of scopolamine and hyoscyamine should be adjusted when the drugs should be administered with antacids in clinical practice.

Purpose: Medical Aid Beneficiaries were surveyed to identify differences in health behaviors, adherence to drug regimen, and quality of life between those people in the Designated Doctor System and those who are not. Methods: A total of 1,327 study subjects were separated into three groups: those in the Designated Doctor System for 2 years, those in for 1 year, and those not in the system. Results: After the introduction of the Designated Doctor System, 55.8% and 67.9%, respectively, of the subjects in the Designated Doctor System complained of inconvenience in relation to hospital use and the patient referral process. Also, the rate of emergency room use or hospitalization guided by the Designated Doctor System was only 8.7% and 6.5%, respectively. There were no significant differences in health behaviors and adherence to drug regimens between those in the Designated Doctor System and those who are not. Conclusion: This study was carried out early in the introduction of the system. Therefore, it is necessary to monitor the positive and negative effects of the Designated Doctor System for a full reflection of its impact.

Hydroxyzine is one of the most popular oral sedatives used in pediatric dentistry. This study aimed to investigate the safety and possible side effects of sedation using hydroxyzine in pediatric dentistry. "Hydroxyzine," "Dental sedation," "Child," and "Safety" and their associated synonyms were searched using the Cochrane Library, Embase, PubMed, KISS, KMBASE, and KoreaMed databases. Academic information and portals of DBpia and RISS were also perused. Altogether, 340 papers were found, among which a total of 24 papers were selected according to the detailed criteria. Nine studies used hydroxyzine as monotherapy, and 10 studies compared its safety when hydroxyzine used as multitherapy. In addition, seven studies employed a drug regimen wherein hydroxyzine was one of the components. All these studies revealed that the adverse events specific to hydroxyzine usage were drowsiness and dryness of the mouth, and that there were respiratory complications due to a synergistic reaction of hydroxyzine. Although classified as a histamine blocker, hydroxyzine with its sedative, antiemetic, anticonvulsant, and anticholinergic properties is an oral sedative available without serious adverse events, If the proper dosage of the drug is used and its synergistic effects with other drugs are ascertained in the route of administration.

This study was attempted to investigate the pharmacokinetic interaction of vancomycin (10 mg/kg, i.v.) and probenecid (7.5. 15, and 30 mg/kg, oral) in rabbits. The area under curve (AUC) of plasma vancomycin concentration was significantly increased (p<0.01) in rabbits when the probenecid was coadministrated. Volume of distribution (Vd) was significantly decreased (p<0.05) in rabbits coadministrated with probenecid (15 and 30 mg/kg) and total body clearance (CLt) was decreased significantly (p<0.05. p<0.01) in rabbits coadministrated with probenecid (7.5, 15 and 30 mg/kg). There was significant correlation between AUC and probenecid dose. From the results of this experiment, it is desirable to adjust dosage regimen of vancomycin for reduction of side or toxic effect when the probenecid is coadministered in clinical practice.

The intraction between cimetidine and rifampicin was studied pharmacokinetically in normal human subjects. The serum level and the area under the serum concentration curve(AUC) of rifampicin administrated orally were elevated significantly by cimetidine. Volume of distribution, total clearance and elimination rate constant of rifampicin were reduced significanyly by cimetidine. Biological half-life of rifampicin was prolonged significantly by cimetidine. The mechanism of this results is probably related to the inhibition of rifampicin metabolism(deacetyl form) or reduction of blood flow in the liver. It is desirable that dosage regimen of rifampicin shoud be adjusted when combined with cimetidine in clinical pharmacy practice.

Although tuberculosis is highly prevalent worldwide, congenital tuberculosis is one of the least common manifestations of the disease. The diagnosis is usually difficult because of the non-specific clinical presentation and the lack of awareness of maternal disease prior to pregnancy and delivery. We present the case of a preterm neonate with congenital tuberculosis, born to a previously healthy mother who had developed severe disseminated tuberculosis during her pregnancy. Once the diagnosis was confirmed in the mother, the congenital infection was confirmed by isolation of Mycobacterium tuberculosis in gastric aspirates, and positive polymerase chain reaction in a cerebrospinal fluid examination. Treatment for tuberculosis with a four-drug regimen resulted in an adequate clinical response in both the mother and infant.

Extrapulmonary tuberculosis (EPTB) constitutes about 20% of all cases of tuberculosis (TB) in Korea. Diagnosing EPTB remains challenging because clinical samples obtained from relatively inaccessible sites may be paucibacillary, thus decreasing the sensitivity of diagnostic tests. Whenever practical, every effort should be made to obtain appropriate specimens for both mycobacteriologic and histopathologic examinations. The measurement of biochemical markers in TB-affected serosal fluids (adenosine deaminase or gamma interferon) and molecular biology techniques such as polymerase chain reaction may be useful adjuncts in the diagnosis of EPTB. Although the disease usually responds to standard anti-TB drug therapy, the ideal regimen and duration of treatment have not yet been established. A paradoxical response frequently occurs during anti-TB therapy. It should be distinguished from other causes of clinical deterioration. Surgery is required mainly to obtain valid diagnostic specimens and to manage complications. Because smear microscopy or culture is not available to monitor patients with EPTB, clinical monitoring is the usual way to assess the response to treatment.
