Voice and speech therapy can be performed in various ways depending on the situation, although it is generally performed in a face-to-face manner. Telepractice refers to the provision of specialized voice and speech therapy by speech-language pathologists for assessment, therapy, and counseling by applying telecommunication technology from a remote location. Recently, due to the pandemic situation and the active use of non-face-to-face platforms, interest in telepractice of voice and speech therapy has increased. Moreover, a growing body of literature has been advocating its clinical usefulness and non-inferiority to traditional face-to-face intervention. In this review, the existing discussions, guidelines, and preliminary studies on non-face-toface voice and speech therapy were summarized, and recommendations on the tools for telepractice were provided.

Black shoot blight disease caused by Erwinia pyrifoliae has serious impacts on quality and yield in pear production in Korea; therefore, rapid and accurate methods for its detection are needed. However, traditional detection methods require a great deal of time and fail to achieve absolute quantification. In the present study, we developed a droplet digital polymerase chain reaction (ddPCR) method for the detection and absolute quantification of E. pyrifoliae using a pair of species-specific primers. The detection range was 10³-10⁷ copies/ml (DNA templates) and cfu/ml (cell culture templates). This new method exhibited good linearity and repeatability and was validated by absolute quantification of E. pyrifoliae DNA copies from samples of artificially inoculated immature pear fruits. Here, we present the first study of ddPCR assay for the detection and quantification of E. pyrifoliae. This method has potential applications in epidemiology and for the early prediction of black shoot blight outbreaks.

This study is aimed to report two cases of chronic kidney disease treated with Korean traditional medicine. We treated the patients with traditional herbal medicine and other treatments including acupuncture. We measured serum creatinine, estimated glomerular filtration rate(eGFR), blood urea nitrogen(BUN), albumin, red blood cell count(RBC), hemoglobin for several times during admission. Case 1 patient was diagnosed with right medulla infarction, bladder stone, chronic kidney disease. The symptoms were quadriplegia, right side dysesthesia, drowsiness and edema. Case 2 patient was diagnosed with acute cerebral infarction, hypertension, chronic kidney disease. The symptoms were right side weakness, delusion, anorexia, low back pain. Case 1 patient was hospitalized for 80 days, and case 2 patient was for 31 days. Korean traditional medicine decreased serum creatinine and BUN level, improved eGFR, increased RBC and hemoglobin. The symptoms of chronic kidney disease such as edema, general body weakness and anorexia were also improved. These cases suggest that Korean traditional medicine can be effective and safe for patients with chronic kidney disease.

Gami-Sopungsan (GS) is one of the traditional korean remedy. We investigated the anti-inflammation and anti-atopic dermatitis (AD) effect of GS. No cytotoxicity of GS was observed in the range of $1{\sim}100{\mu}g/m{\ell}$ on Raw 264.7 cells. The Inflammatory response of Raw 264.7 cells were induced by lipopolysaccharide (LPS), followed by GS treatment at indicated concentrations (0, 1, 10 and $100{\mu}g/m{\ell}$). At $100{\mu}g/m{\ell}$ concentration, GS showed inhibitory effect on LPS-induced nitric oxide production by 20%. Production of IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ was decreased by approximately 56%, 36% and 79%, respectively upon GS treatment at $100{\mu}g/m{\ell}$. 200 mg/kg of GS was orally administered to NC/Nga mice, where AD was induced by 1-chloro 2,4-dinitrobenzene. There were no significant difference between GS treated group and the control group on body weight and food intake changes during growth. The back skin of GS group showed decrease in erythema, pruritus, dry skin, edema, excoriation, erosion and lichenification level through naked eye observations. In addition, leukocyte infiltration and the thickness of epidermis were significantly decreased in the skin tissues (back and ear). The serum IgE levels were decreased by 28.8% in the GS treated group. The GS treated group showed remarkable inhibition of IL-4 (83%), IL-5 (95%), IL-6 (62%) and TNF-${\alpha}$ (84%) in serum, indicating that GS has similar or higher efficacy than those of the dexamethasone treated group. From the results above, we conclude that GS has significant anti-inflammation and anti-AD effects on Raw 264.7 cells and NC/Nga mice. The results should provide fundamental and valuable data for the research on natural products being developed against atopic dermatitis.

APA-01, which is an aqueous extract of five Chinese herbs, is a modified formula of Huoxiang-Zhengqi-San. The effect of new herb extract on immune response was investigated. The parameter examined to assess apparent immune response of APA-01 in mice included changes of body weight, relative weight of immune organs, cell proliferation and cytokine gene expression. The body weight and relative weight of immune organs were not significantly changed among the tested groups. In the spleen cell prolijeration assay, APA-01 increased the cell proliferation in a dose-dependent manner. Methotrexate (MTX), an agent of immune suppression, inhibited the spleen cell proliferation (IC/sub 50/: 800㎍/㎖). However, APA-01 significantly inhibited the suppression of mouse spleen cell proliferation. Therefore, it seems that APA-01 has a reducing effect of immune suppression. Immunomodulatory effect of APA-01 was further investigated using reverse transcription polymerase chain reaction (RT-PCR) in mouse spleen cells. In RT-PCR test, APA-01 enhanced the expression of cyclooxygenase-2 (COX-2) mRNA in a dose-dependent manner. In spite of immune suppression by MTX, COX-2 mRNA was induced by co-treatment with APA-01. These results suggest that APA-01 stimulates the proliferation of spleen cells, regulates the expression of COX-2 mRNA, and accelerates the recovery of inhibition of spleen cell proliferation induced by MTX, thus providing the immunological basis for clinical benefit of APA-01.

Polychlorinated biphenyls(PCBs) are large scale industrial chemicals which are using in diverse applications. The goal of this study was to determine if exposure to 2,2',5,5'-tetrachlorobiphenyl (PCB 52) leads to an increase in the production of active oxidants, and subsequently promotes apoptosis of neuronal SK-N-MC cells. Reactive oxygen species (ROS) formation was examined in SK-N-MC cells after treatment of PCB 52 by concentrations and incubation times, respectively. It showed that the rate of ROS production in the cells was increased in a does-dependent manner to 45 min, followed by a return towards control levels after 120 min treatment. We also examined the association of PCB-induced apoptosis with the modulation of biomakers of oxidative damage to lipids (malondialdehyde [MDA]) in SK-N-MC cells. Increased MDA was observed in a dose-dependent manner in groups treated with 10, 15, and 20 figJ me of PCB 52 for 24 h. After treatment of PCB 52, the cells did not show any significant change in the rate of Cu/Zn-superoxide dismutase (Cu/Zn-SOD) activity. Whereas, the cells had a two-fold greater rate of change in catalase activity at 20 ㎍/㎖ of PCB 52 for 24 h when compared to control group. Korean Ginseng is one of the most important crude drugs which has been used as a traditional Oriental medicine. We next investigated protective effect of extracts of ginseng on cytotoxicity induced by PCB 52 in SK-N-MC cells. Pretreatment of SK-N-MC cells with 25-200 μg/ml of ginseng were reduced cell death in a dose-dependent manner in PCB 52-treated cells. To examine the sensitivity of beta-catenin to ginseng, the protective effect of a range of ginseng concentrations was examined in SK-N-MC cells treated with PCB 52. The result demonstrated that ginseng efficiently blocked PCB 52 inducible beta-catenin proteolysis in a concentration dependent manner. The ROS formation was also measured in the presences of extract of ginseng and superoxide dismutase (inhibitor of oxygen free radical production). The both SOD (400 U/ml) and ginseng (200 μg/ml) significantly inhibited RDS generation in PCB 52-treated group.

In "Hwangjenaegyeong(黃帝內經)", the name of blood vessels is closely related to images of the river, and the word for blood vessel contains the following meaning, such as blood vessel, blood wind as well as blood stasis and so on. In a physiological perspective, the unobstructed blood vessel and normal operation blood are important symbols of health, for blood is the basis for human survival, physical activity and mental activity. In pathology, the external cold, excessive seven emotions and a biased diet can cause many kinds of abnormalities of the blood vessels, which can in turn become causes for a variety of diseases. The theory of blood vessels in "Hwangjenaegyeong" can provide guidance for diagnosis and treatment of cardiovascular diseases in practice.

Cancer treatment remains a serious problem worldwide. Analysis of the relationship between cancer cells and normal cells reveals that these two share characteristics in contradiction, thus could be analyzed by using contradictory principles. Under the theory of contradictory principles, induction of a dormant state or reversal of cancer cells is an important treatment strategy beyond traditional cytotoxic therapy. Normal cells are also the targets and under the influence of anti-cancer treatments and should be considered during therapy. Findings based on crosstalk between these two cell types may offer opportunities for the development of new biomarkers and therapies.
