Objectives : Gal-Geun-Tang (GT) has been described from SANGHAN in Korean traditional medicine and known to act against cold, fever, hypertension, and nasal catarrh. However, little has yet been learned about the effect of GT on immune function. In the current study, in vitro and in vivo immunomodulatory activity of GT (water extract) was investigated.Methods : Water extract of GT induced in vitro proliferation of spleen cells and significantly increased their proliferative responses during anti-CD3 activation. Using purified splenic T and B cells, it was revealed that GT has a mitogenic activity to B cells and promotes their proliferation induced by lipopolysaccharide, whereas T cell proliferation was not triggered and GT was rather inhibitory to T cell activation caused by anti-CD3 antibody. In the presence of antigen presenting cells (APC), GT addition resulted in a significant increase of IFNγ and IL-4, but not IL-2, production. However, addition of high concentration (1,000㎍/㎖) of GT led to a marked reduction in T cell cytokine production and under such condition, GT facilitated apoptosis of T cells when examined by flow cytometry with propidium iodide staining.Results : In vivo immunomdulation of GT was also investigated using a mouse model. Following keyhole limpet hemocyanin (KLH) immunization, GT (1 ㎎/day) was orally administered for 9 days. Cell numbers in thymus, spleen and peripheral blood were not altered by GT administration, indicating that such dose is not immunotoxic. Cell numbers in draining lymph nodes (LN) and ex vivo Ag-specific proliferation of LN cells were significantly elevated by GT administration. However, any preferential stimulation of T or B and CD4⁺ or CD8⁺ T cell subpopulations was not observed in a flow cytometric analysis of LN cells. This result shows that GT does not promote in vivo B cell proliferation while GT enhances Ag-specific proliferation of LN cells, unlike what was observed in vitro.Conclusions : For a further understanding of in vivo immunomodulatory activity of GT, ex vivo cytokine production of LN cells obtained from KLH-immunized mice was evaluated. Ag-specific IFNγ production was significantly higher in GT-treated mice when compared to PBS-treated control mice. In contrast, IL-4 production in GT-treated group was comparable to control group unlike to in vitro data. In addition, GT administration did not result in any significant differences in serum levels of Ig (IgM, IgG1 and IgG2a) between GT-treated and control groups. Taken together, these data strongly support that GT promotes immune response, more profoundly type 1 helper T cell (Th1) activity and GT may be applicable for treatment of intracellular parasite infection such as viral diseases.

A cross-sectional study was conducted to investigate the prevalence of canine influenza (CI) infection in pet dogs and canine parvovirus (CPV) infection in street dogs of different age and sex by collecting rectal and nasal swab samples from three districts, Dhaka, Mymensingh and Sirajgonj, in Bangladesh using a RapiGEN$^{(R)}$ Canine Influenza Virus Ag Test kit and RapiGEN$^{(R)}$ Canine Parvovirus Ag Test Kit. Out of 114 rectal swabs and 115 nasal swab samples, the overall prevalence of CI and CPV was found to be 11.30% and 32.45%, respectively. The prevalence of parvovirus infection was found to be significantly higher in puppies and dogs 6 months of age (50.0%) than those > 24 months of age (p = 0.005). The prevalence was also higher in males (34.42%) than females (30.18%). The prevalence of CI was higher (30.43%) in dogs up to 6 months of age (p = 0.011) than 6-12 month (7.93%) and 12-18 month (6.66%) old dogs. Moreover, the prevalence of CI was found to be higher in males (16.10%) than females (5.66%). The prevalence of CPV infection also varied significantly in different study areas (p = 0.0029), with 12.72%, 12.5% and 7.14% of dogs found to be CI positive in Dhaka, Mymensingh and Sirajgonj, respectively. Overall, the highest prevalence of CI was found in local breeds (6.08%) followed by German shepherds and Keeshonds (1.73%), and Bloodhounds and Terriers (0.86%). Additionally, there were more positive CI found in unvaccinated dogs (14.81%) than vaccinated (2.94%) dogs. Dogs with flu-like symptoms were more positive (19.23%) for CI relative to those without flu-like symptoms (4.76%) samples. Overall, the results of this study indicate that canine vaccination should be initiated to prevent the occurrence of diseases and that regular monitoring should be continued in Bangladesh.

Purpose : It is known that carriage rates of Staphylococcus aureus (S. aureus) are highest in newborns and that the asymptomatic carriage of methicillin-resistant Staphylococcus aureus (MRSA) is associated with invasive MRSA infection with the colonizing strain. This study was carried out to investigate the carriage rates of MRSA in neonates with neonatal jaundice. Methods : We reviewed the medical records of 545 neonates admitted with neonatal jaundice to neonatal intensive care units between January 2006 and December 2010. Nasal and inguinal swab specimens had been taken from them and cultured for the isolation of S. aureus. Antimicrobial susceptibility tests had been done for such isolates to determine methicillinresistance. Results : Out of 545 neonates, 318 (58.3%) were colonized with S. aureus and 214 (39.3%) were colonized with MRSA. Results of the antibiogram analysis showed that 65.7% of MRSA isolates were likely to be community-associated (CA) MRSA. Conclusion : Based on the MRSA carriage rate of 39.3%, a surveillance program for MRSA colonization is considered necessary in neonates transferred from other clinics or hospitals. Out of MRSA isolates, 65.7% were likely to be CA-MRSA. This suggests that CA-MRSA strains were already present in obstetric clinic environments where the neonates were born. It is thought that MRSA surveillance programs in these environments are also necessary.

Acute maxillary sinusitis is a common disorder affecting children. Untreated acute sinusitis can develop into chronic sinusitis, and complications, such as orbital cellulitis or abscess, can occur. Maxillary sinusitis of odontogenic origin is not a well-recognized condition and is frequently missed in children. As an odontogenic source of sinusitis, the dentigerous cyst is one of the most prevalent types of odontogenic cysts, and it is associated with the crown of an unerupted or developing tooth. This report concerns a nine-year-old boy who was diagnosed with maxillary sinusitis originating from a dentigerous cyst with supernumerary teeth. The boy visited our pediatric clinic presenting with rhinorrhea and nasal obstruction and was initially diagnosed with maxillary sinusitis only. With antibiotic treatment, his symptoms seemed to improve, but after 2 months, he came to our clinic with left facial swelling with persistent rhinorrhea and nasal obstruction. Radiographic examinations of the sinuses were performed, and he was diagnosed with maxillary sinusitis originating from a dentigerous cyst with supernumerary teeth. After a surgical procedure involving the removal of the dentigerous cyst with supernumerary teeth, the symptoms of sinusitis gradually diminished. There are only very few cases in the pediatric medical literature that remind us that odontogenic origin can cause maxillary sinusitis in children. Our patient can act as a reminder to general pediatricians to include dentigerous cysts in the differential diagnosis of maxillary sinusitis.

Objectives : This study is to report a case of otitis media with effusion accompanied by atopic dermatitis improved by Korean medicine monotherapy. Methods : A 31-year-old woman patient visited our clinic for aural fullness, hearing loss, and tinnitus of the left ear on August 14th, 2021. She also had abdominal pain, diarrhea, and general weakness because of side effects of antibiotics. Besides, she had nasal congestion, rhinorrhea, and dry skin. Through otoscopy, her tympanum was fully filled with yellow effusion. She only took Korean medicine therapy including acupuncture and herbal medicine weekly. The treatment continued for about 4 months(total 14 visits) until December 4th, 2021. Otoscopy, numerical rating scale(NRS), scoring atopic dermatitis(SCORAD) index were used to assess the symptoms. Results : On August 30, 2021, her intestinal symptoms improved. The left tympanum was recovered to normal condition as the treatment continued. The effusion disappeared on October 16th, 2021. On November 6th, 2021, peritympanic blood congestion also almost alleviated. Subjective symptoms including aural fullness, hearing loss, and tinnitus disappeared on October 16, 2021. Nasal symptoms and dry skin also improved. The SCORAD index dropped from 15 to 4. Conclusions : These results suggests that otitis media with effusion can be sufficiently managed by Korean medicine therapy. Further, active application of Korean medicine therapy to common otolaryngological diseases is necessary.

Purpose : To compare the size and bone wall thickness of the maxillary sinus in normal, preoperative and postoperative maxillary sinusitis patients. Materials and Methods : The author analyzed CT images of both left and right maxillary sinuses in 357 patients who visited Chonbuk National University Hospital between January 1997 and December 1998. The size and bone wall thickness of the maxillary sinus of normal, inflammatory and post-Caldwell-Luc groups were compared. Results: The significant differences of transverse, maximum medio-lateral, maximum supero-inferior dimensions and medio-lateral dimension at nasal floor level between normal and post-Caldwell-Luc groups were found (P<0.05). And the significant differences of antero-posterior dimensions between inflammatory and post-Caldwell-Luc group were found (P<0.05). But, no significant differences of vertical height dimensions between groups was found (P>0.05). The significant differences of postero-lateral, infero-lateral and medial wall thickness between normal and post-Caldwell-Luc groups were found (P<0.05). Conclusion : The results of this study will aid in the diagnosis and treatment of maxillary sinus diseases and post operative treatment planning.

Background: Welders are exposed to many known and suspected carcinogens. An excess lung cancer risk among welders is well established, but whether this is attributable to welding fumes is unclear. Excess risks of other cancers have been suggested, but not established. We investigated welding cancer risks in the population-based Canadian Census Health and Environmental Cohort. Methods: Among 1.1 million male workers, 12,845 welders were identified using Standard Occupational Classification codes and followed through retrospective linkage of 1991 Canadian Long Form Census and Canadian Cancer Registry (1992-2010) records. Hazard ratios (HRs) were calculated using Cox proportional hazards models based on estimated risks of lung cancer, mesothelioma, and nasal, brain, stomach, kidney, and bladder cancers, and ocular melanoma. Lung cancer histological subtypes and risks by industry group and for occasional welders were examined. Some analyses restricted comparisons to blue-collar workers to minimize effects of potential confounders. Results: Among welders, elevated risks were observed for lung cancer [HR: 1.16, 95% confidence interval (CI): 1.03-1.31], mesothelioma (HR: 1.78, 95% CI: 1.01-3.18), bladder cancer (HR: 1.40, 95% CI: 1.15-1.70), and kidney cancer (HR: 1.30, 95% CI: 1.01-1.67). When restricted to blue-collar workers, lung cancer and mesothelioma risks were attenuated, while bladder and kidney cancer risks increased. Conclusion: Excess risks of lung cancer and mesothelioma may be partly attributable to factors including smoking and asbestos. Welding-specific exposures may increase bladder and kidney cancer risks, and particular sources of exposure should be investigated. Studies that are able to disentangle welding effects from smoking and asbestos exposure are needed.

This study investigated the symptoms, medical and occupational history of 424 workers of 5 reactive dye Industries in the Inchon area in Korea. The study was performed on March 6 and July 19, 1989. The tests applied to the subjects were : serum total IgE, specific IgE, skin prick test with 7 inhalatory antigens, pulmonary function test, chest X-ray, methacholine test, and bronchoprovocation test. The workers were classified according to these tests into 4 groups (healthy, realtively healthy, need careful medical observation, and occupational asthma), and were compared in terms of the group characteristics and the symptom prevalence. The prevalece of occupational asthma of workers in reactive dye was 5.9% Significant differences were observed among the 4 groups. The groups were significantly different in the variables of sex and duration of smoking among their general characteristics ; and dyspnea, wheezing, chest pain, cough, nasal symptoms and sore throat among symptoms ; asthma, bronchitis, and other respiratory diseases with respect to their past medical history. This study suggests that we should pay special attention to the workers exposed to the risk of occupational asthma.

Bacterial pathogens were isolated from 36 dogs with respiratory signs, that were submitted to Veterinary Clinics in Jeju, including Veterinary Medical Teaching Hospital in Cheju National University. Of 36 isolates, 16 (44.4%) bacterial pathogens were Gram-positive and 20 (55.6%) were Gram-negative. Gram-positive bacteria identified with API Staph were 12 S. intermedius (33.3%), 2 S. aureus (5.6%), 1 S. haemolyticum (2.8%), and 1 S. xylosus (2.8%). Gram-negative organisms identified with API 20E or API NE included 8 Bordetella bronchiseptica (22.2%), 6 Escherichia coli (16.7%), 4 Pasteurella spp. (11.1%), 1 Enterobacter intermedius (2.8%), and 1 Oligella ureolytica (2.8%). Both Staphylococcus spp. isolates and Gram-negative pathogens were resistant to one or more antibiotics, including ampicillin (AM), amoxicillin/clavulanic acid (AMC), chloramphenicol (C), cefazolin (CZ), erythromycin (E), gentamicin (GM), kanamycin (K), lincomycin (L), oxacillin (OX), trimethoprim/sulfamethoxazole (SXT), and tetracycline (TE). All Staphylococcus spp. were susceptible to AMC, OX and VA, while many isolates were highly resistant to L (87.5%), E (68.8%), P (62.5%), and AM (56.3%). Antibiotic-resistant patterns of staphylococcal isolates were shown ranges from single to 9-resistant patterns. Resistant rates to antibiotics of Gram-negative bacteria were usually higher than those of Staphylococcus spp. in this study. Most Gram-negative bacteria were highly resistant to L (90.0%), AM (85.0%), E (85.0%), P (85.0%), OX (80.0%), and CZ (75.0%). B. bronchiseptica isolates showed 5 to 8 antibiotics-resistant patterns and Pasteurella spp., 2 to 8-resistant patterns. In particular, all 6 E. coli isolates were resistant to more than 9 different kinds of antibiotics, including one strain resistant to all antibiotics tested.
