As Kamisipjeondaebotang (KSD) extract is an herbal ingredient, safety is very important due to possible cell poisoning or heavy metal toxicity to organs when administered to humans or animals. Accordingly, this study examined the antioxidant and anti-inflammatory effects of KSD extract to confirm its medicinal safety by using RAW 264.7 cells after heavy metal screening, functional index test of the liver and kidney, and cell survival rate test. Heavy metals were not found in KSD extracts or were less than standard amounts. Liver function indices such as aspartate aminotransferase and alanine aminotransferase revealed low values and kidney function indices such as creatinine and blood urea nitrogen were not significantly different from the normal group. This proved the safety to the human. RAW 264.7 cells showed no poisoning compared to the control group in terms of survival rate. Regarding the antioxidant effect of KSD extract, 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity and 2,2'-azino-bis(3-ethylbenzothiazo-line-6-sulphonic acid) radical scavenging activity increased at concentrations over $10{\mu}g/mL$. The anti-inflammatory effect of KSD extract significantly decreased based on the amount of nitric oxide at concentrations of 10 and $100{\mu}g/mL$ compared to the control group. Expression of interleukin (IL)-$1{\beta}$ and IL-6 decreased in a concentration-dependent manner. There was no significant difference in tumor necrosis factor-${\alpha}$ level. Based on the results, KSD can be regarded as a safe antioxidant with anti-inflammatory effects for fracture treatment.

Objectives: The purpose of this study was to check the therapeutic effect of the Dendropanax morbifera Pharmacopuncture for insomnia and cognition caused by psychosocial stress. Methods: We separated Wistar rats (older than age 10 weeks, 300 g) into normal, control, positive control (Zolpidem administered, PC), and Dendropanax morbifera Pharmacopuncture experimental groups (DPA). Psychosocial stress such as circadian rhythm change, clammy straw, predator stress, restraint stress, noise bursts, and flashing lights were applied to the control, PC, DPA groups. The Dendropanax morbifera Pharmacopuncture group was given 0.5×, 1× and 2× amount concentration of Dendropanax morbifera Pharmacopuncture, respectively. The levels of Melatonin, Serotonin, Corticosterone, GABA, BDNF and CREB were measured, and the Y-maze test, weight and blood test were performed. Results: In all of the DPA groups, the Melatonin level showed no noticeable difference. In the DPA-2x group, Serotonin increased significantly. In all the experimental groups, Corticosterone decreased significantly and GABA showed increasing tendency. The DPA-1x and DPA-2x groups showed remarkable increase in BDNF and DPA-0.5x and the DPA-2x groups showed significant increase in CREB. The DPA-2x group showed remarkable increase in the Alternation behavior category of the Y-maze test. In all of the experimental groups the weight change showed increasing tendency, whereas no noticeable differences were found among all experimental groups regarding AST, ALT, BUN, Creatinine and CBC. Conclusions: Dendropanax morbifera Pharmacopuncture increases levels of serotonin and GABA, decreases corticosterone, increases levels of BDNF and CREB, and increases the ratio of alternation behavior in the Y-maze test. Thus, I suggest that Dendropanax morbifera Pharmacopuncture has the effect of treating insomnia caused by psychosocial stress, activating the brain, and improving cognition.

Carry over contamination has been reduced in some systems by flushing the internal and external surfaces of the sample probe with copious amount of diluent. It between specimens should be kept as small as possible. A built-in, continuous-flow wash reservoir, which allows the simultaneous washing of the interior and exterior of the syringe needles, addresses this issue. In addition, residual contamination can further be prevented through the use of efficient needle rinsing procedures. In discrete systems with disposable reaction vessels and measuring cuvets, any carry over is entirely caused by the pipetting system. In analyzers with reuseable cuvets or flow cells, carry over may arise at every point through which high samples pass sequentially. Therefore, disposable sample probe tips can eliminate both the contamination of one sample by another inside the probe and the carry over of in specimen into the specimen in the cup. The results of the applicative carry over experiment studied on 21 items for total protein (TP), albumin (ALB), total bilirubin (TB), alkaline phosphatase (ALP), aspratate aminotranferase (AST), alanine aminotranferase (ALT), gamma glutamyl transferase (GGT), creatinine kinase (CK), lactic dehydrogenase (LD), creatnine (CRE), blood urea nitrogen (BUN), uric acid (UA), total cholesterol (TC), triglyceride (TG), glucose (GLU), amylase (AMY), calcium (CA), inorganic phosphorus (IP), sodium (Na), potassium (K), chloride (CL) tests in chematology were as follows. Evaluation of process performance less than 1% in all tests was very good, but a percentage of ALB, TP, TB, ALP, CRE, UA, TC, GLU, AMY, IP, K, Na, and CL was 0%, implying no carry over. Other tests were ALT(-0.08%), GGT(-0.09%), CK(0.08%), LD(0.06%), BUN(0.12%), TG (-0.06%), and CA(0.89%).

We investigated whether two-kinds of mixture (NHDT-1 and NHDT-2) mainly composed of Hovenia dulcis Thunb had beneficial actions for alcohol and acetaldehyde degradation in acute alcohol treatment and liver protection from fatty liver induced by chronic alcohol administration. In acute alcohol degradation experiment, serum alcohol and acetaldehyde concentrations exhibited lower 1, 3 and 5 hours after taking 3 g ethanol per kg body weight in NHDT-1 treated rats, but not NHDT-2 including ginseng. On the contrast to the acute effect on alcohol degradation, the long-term alcohol administration revealed that NHDT-2, not NHDT-1, protected the increase in serum concentration of aspartate aminotransferase, alanine aminotrasferase and ${\gamma}-triglyceride$ metabolism similar to the rats not consuming alcohol, leading to decreased triglyceride accumulation in blood and liver. In liver morphological study, NHDT-1 preserved the regular hepatocyte morphology, decreased fat accumulation and reduced sinusoidal leukocyte infiltration in hepatocytes. In conclusion, NHDT-1 plays an important role in alcohol and acetaldehyde degradation without protecting liver damage while NHDT-2 works as hepatocyte protector from alcohol mediated damage.

In order to reduce the social and economic costs due to the increase in dementia patients, which is a representative senile disease in an aging society, it will be important to prevent dementia and to detect and treat early in high-risk groups. This study reported the results of treatment for the elderly with high risk of dementia and depression who received Korean medicine (KM) treatment in 9 KM clinics. Medical charts were surveyed on 116 patients with high risk of dementia and depression who received KM treatment at 9 KM clinics in Gangseo-gu from September 1, 2020 to December 31, 2020. The majority of the patients were female(76.72%), the average age was 71.66±7.18 years old, and the average education level was 8.96±3.91 years. The average treatment period was 61.47±10.30 days, the average number of treatments was 15.38±1.06 times, and both acupuncture and herbal medicine were administered. After receiving KM treatment, cognitive assessment scores such as MMSE-DS and MoCA-K, depression-related GDSSF-K score, dementia knowledge, attitude, and preventive behavior, blood debilitation scale, and GQOL-D score were improved compared to before. There was no specific adverse reaction except that one patient with elevated AST and ALT levels was observed. This study showed improvement in cognitive function, depression, dementia-related scale, and quality of life in high-risk groups for dementia and depression over 60 years old who received KM treatment. More systematic and large-scale planned clinical studies will be needed.

Olive flounder (Paralichthys olivaceus) (Weight 110.9±17.1 g, length 22.3±1.2 cm) were exposed to waterborne nitrite at 0, 30, 60, 120, 240, 480 and 960 mg NO₂^-/L according to water temperature at 20℃ and 25℃ for 96 hours. The lethal concentration 50 (LC₅₀) of olive flounder, P. olivaceus exposed to waterborne nitrite was 513.87 mg NO₂^-/L at 20℃ and 208.35 mg NO₂^-/L at 25℃, which means a significant difference in LC₅₀ by the water temperature. Hemoglobin and hematocrit were significantly decreased by waterborne nitrite exposure. The inorganic component, plasma calcium, was significantly decreased, and the organic components such as plasma glucose and cholesterol were significantly decreased showing a similar tendency with calcium. In enzymatic components, the AST and ALP were also significantly decreased by nitrite exposure. The results of this study indicate that exposure to nitrite can affect the survival and hematological physiology of P. olivaceus, and the effect of exposure to nitrite had a significant effect on nitrite toxicity depending on the water temperature.

The inhibitory effects of Asparagus cochinchinensis against inflammatory response induced by lipopolysaccharide (LPS), substance P and phthalic anhydride (PA) treatment were recently reported for some cell lines and animal models. To evaluate the hepatotoxicity and nephrotoxicity of A. cochinchinensis toward the livers and kidneys of ICR mice, alterations in related markers including body weight, organ weight, urine composition, liver pathology and kidney pathology were analyzed in male and female ICR mice after oral administration of 150, 300 and 600 mg/kg body weight/day saponin-enriched extract of A. cochinchinensis (SEAC) for 14 days. The saponin, total flavonoid and total phenol levels were found to be 57.2, 88.5 and 102.1 mg/g in SEAC, respectively, and the scavenging activity of SEAC gradually increased in a dose-dependent manner. Moreover, body and organ weight, clinical phenotypes, urine parameters and mice mortality did not differ between the vehicle and SEAC treated group. Furthermore, no significant alterations were measured in alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), blood urea nitrogen (BUN) and the serum creatinine (Cr) in the SEAC treated group relative to the vehicle treated group. Moreover, the specific pathological features induced by most toxic compounds were not observed upon liver and kidney histological analysis. Overall, the results of the present study suggest that SEAC does not induce any specific toxicity in the livers and kidneys of male and female ICR mice at doses of 600 mg/kg body weight/day.

In principle, the blood galactose level may be determined conveniently with a strip-type biosensor similar to that for glucose. In this study, we describe the development of a disposable galactose biosensor strip for point-of-care testing. The sensor strip is constructed with screen-printed carbon paste electrode (SPCE) and sample amount (< $100{\mu}L$). The developed strip the galactose level in less than 90 s using bienzymatic system of galactose oxidase (GAO) and horseradish peroxidase (HRP). The effects of pH, mediator (1,1-ferrocenedimethanol) concentration, ratio of enzymes, and applied potential were determined preliminarily with glassy carbon electrodes, and optimized further with the strip-type electrodes. The sensor exhibits linear response in the range of $0{\sim}400{\mu}M$ ($r^2$ = 0.997, S/N = 3). Since a low working potential, in principle, the fabricated disposable galactose biosensor has -100 mV (vs. Ag/AgCl), it is applied for the detection of galactose, interfering responses from common interferents such as ascorbic acid, uric acid and acetaminophen could be minimized. The sensor has been used to determine the total galactose level in standard samples with satisfactory reproducibility (CV = 5 %).
