  • Variable systemic diseases affect larynx and vocal fold and result in voice change. Asthma and chronic obstructive pulmonary disease make increase of intra-abdomimal pressure followed by reflux of gastric acid, which stimulate vagal-bronchopulomary reflex aggravating cough and respiratory disturbance. Fungal laryngitis in the general population is extremely rare, but can occur in immunocompromised AIDS patients. Although, initially, empirical antifungal therapy for candidiasis is often given without biopsy, diagnostic direct laryngoscopy and biopsy is imperative if a substantial clinical response is not rapidly achieved. In the highly active anti-retroviral therapy era, HIV-positive patients are living longer and are at higher risk for developing non-AIDS-defining malignancies. The incidence of head and neck cancer (HNC) which is related with human papilloma virus infection has increased. The survival is significantly lower among the AIDS-HNC patients with CD4 counts ${\leq}200cells/{\mu}L$. Rheumatoid arthritis (RA) cause voice disturbance by developing cricoarytenoid joints fixation or nodule on vocal fold. Post-menopausal voice disorder (PMVD) is caused by decreased secretion of estrogen-progesterone resulting in decrease of fundamental frequency (F0). Hormonal replacement therapy is helpful to reduce F0 decrease. RA and PMVD result in slight voice change, but it could crucial in professional voice user.

  • The chitosan-coated liposomes (chitosomes) were designed to improve the stability in the gastrointestinal (GI) tract and to enhance the efficacy for oral drug delivery of liposomes. The phosphatic acid (PA)-incorporated anionic liposomes were surface-coated with water soluble chitosan (WSC) by electro-ionic interaction. The shape of the chitosomes observed by transmission electron microscopy (TEM) was spherical in all the formulations and the coating layer by WSC could be founded through TEM images. The mean size and the zeta potential values of the chitosomes increased significantly with depending on the content of WSC added for coating the liposomes. The stability of the chitosomes in the GI tract was confirmed through the change of relative turbidity of the liposomal suspension. The plain liposomes (plasomes) suspension without adding WSC clearly showed the change of relatively turbidity in simulated gastric fluid (SGF), while the change degree of turbidity of the chitosomes in the SGF decreased as increasing of WSC content added for coating liposome. In the 5-CF release study from the plasomes and chitosomes, the plasomes released >90% of the initial 5-CF content at 4 h of release measurement. In contrast, the chitosomes released below 40% of initial content of 5-CF. In conclusion, these results indicate that the chitosomes can be used as a potential carrier for effective oral drug delivery.

  • General phannacological properties of IH-901, a new pharmacological composition as an intestinal metabolite formed from ginseng protopanaxadiol saponins, were investigated in experimental animals administered orally and in vitro test system. IH-901 had no effects on general behavior, pentobarbital sleeping time, spontaneous motor activity, motor coordination of mice, normal body temperature, chemoshock produced by pentylenetetrazole and writhing syndromes induced by 0.8% acetic acid at the dose of 25 and 250 mg/kg. Gastric secretion of rats and intestinal motility in mice were not also influenced by the administration of IH-901 at doses of 25 and 250 mg/kg. IH-901 (25 and 250 mg/kg) did not change the mean arterial blood pressure and heart rate in conscious rats. IH-901 had no effect on the respiratory rate at the same doses when it was given to anesthetized rats. In in vitro experiments, IH-90l at the concentration of 25$\mu\textrm{g}$/L did not show any direct effect and inhibitory or augmentative action on the histamine-or acetylcholine-induced contractions in the isolated ileum of guinea-pig. Based on these results, it was concluded that IH-901 did not induce any adverse effects in experimental animals.

  • Damp Heat is a combination of Damp and Heat if conditioned internally and externally, and constitutes vital Ki as well as pathogenic Ki. Damp Heat, as vital Ki, is one of the essential factors in forming the body and preserving life activity, and on the other hand, as pathogenic Ki, it causes undear mentality, gastric discomfort with acid regurgitation, San disease(疝病), cardiac beriberi, flaccidity symtoms, muscular atonia or contracture and dark or cloudy urine. In Hyungsang Medicine, the Dam type develops Damp Heat disease mostly due to Heat, and the treatment is to promote urination by clearing Heat; on the other hand, in the Bangwang type, Damp is the major cause and the treatment is to induce sweating and eliminate Damp.

  • Lactobacillus plantarum KU15149 was demonstrated to have probiotic behavior and functions, including antioxidant and anti-inflammatory activity. L. plantarum KU15149 obtained from homemade diced-radish kimchi has a high survival rate under artificial gastric acid (pH 2.5, 0.3% pepsin) and bile salt (0.3% oxgall) conditions. However, L. plantarum KU15149 did not produce β-glucuronidase, which is known to be a carcinogenic enzyme with resistance to several antibiotics, such as gentamycin, kanamycin, streptomycin, tetracycline, and ciprofloxacin. L. plantarum KU15149 strongly adhered to HT-29 cells and had high antioxidant activity in terms of 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical-scavenging and β-carotene bleaching assays. L. plantarum KU15149 also exhibited a pronounced inhibition of nitric oxide (NO) production, along with expression of nitric oxide synthase (iNOS) and cyclooxygenase -2 (COX-2) as well as pro-inflammatory cytokines, such as TNF-α, IL-1β, and IL-6, when RAW 264.7 cells were stimulated with LPS. Therefore, L. plantarum KU15149 exhibited pharmaceutical functionality as a potential probiotic.

  • This study was conducted to investigate effects of Dansambohyultang on serum gastrin, secretin release and CNS in rats and mice. One group of seven rats was intactly in normal condition, the other group of seven rats was respectively heated, starved, and stressfully immobilized. The third group of seven rats was provided with Dansambohyultang before the stress, and the forth one after the stress. And, gastrin concentration and secretin concentration were measured. Mice were studied with regard to convulsion time, total sleep time and analegic effects on cental nerve system. The results were as follows: 1. Gastrin concentration was significantly decreased, and secretin concentration was significantly increased. 2. Analegic effect by acetic acid method was recognizably observed. 3. Effect of total sleep time done by pentobarbital-Na was recognizably observed. 4. Anti-convulsion effects induced by strychnine, picrotoxin and caffeine were recognizable. It is inferred from above results that Dansambohyultang inhibits gastin release, stimulates secretin release and palliate the pain.

  • The potential probiotic of a total of 15 Bacillus species isolated from Korean soybean paste (doenjang) was evaluated. Among those tested, the CSY191 and CSY388 strains were selected as probiotic bacteria due to their acid and bile tolerance, respectively. These strains were classified as Bacillus subtilis based on morphological, physiological, and chemotaxonomic features as well as on phylogenetic analysis based on their 16S rDNA sequences. These strains CSY191 and CSY388 showed a significant survival with rate range of 30.0 to 58.3% and of 31.0% to 58.1%, respectively, under artificial gastric acidic conditions at pH 3.0. These CSY191 and CSY388 strains appeared to have high antimicrobial activity against Salmonella Typhimurium, Bacillus cereus and Listeria monocytogenes. Also, methanol extractions (surfactin-like compounds) of strain CSY191 and strain CSY388 activated RAW264.7 microphages and induced the production of nitric oxide (NO) in a concentration-dependent manner, respectively. Therefore, strain CSY191 and strain CSY388 can be used as potential probiotics.
