The purpose of this study was to propose the optimal blending ratio of honey, dextrose syrup and salt with regard to the amount of soybean powder for the manufacture of soybean Dasik. For the establishment of addition amount of honey, dextrose syrup and salt, the sensory characteristics were compared in relation to the physiochemical characteristics and color values. The results were summarized as follows: Soybean Dasik contained 16.77 % protein. As the results of sensory evaluation in according to color values, taste and moistness, the optimal blending ratio of honey and dextrose syrup was 80~90%, and that of salt 0.06% in proportion to the total weight of soybean powder. As the test results of mechanical characteristics, hardness of soybean Dasik decreased as the increasing of the addition amount of honey and dextrose syrup. Cohesiveness, gumminess, brittleness and springiness did not show any significant differences statistically. Lightness(L) decreased as the increasing of addition amount of honey and dextrose syrup. Redness(a) was high at the 90% addition level, but yellowness(b) not significantly different at the 70, 80 and 90% level of honey and dextrose syrup to the total weight of soybean powder. Therefore, the optimal blending ratio of soybean Dasik was proposed at the levels of 45% honey, 45% dextrose syrup and 0.06% salt to the total weight of soybean powder.

Background: Prolotherapy is a proliferation therapy as an alternative medicine. A combination of dextrose solution and lidocaine is usually used in prolotherapy. The concentrations of dextrose and lidocaine used in the clinical field are very high (dextrose 10%-25%, lidocaine 0.075%-1%). Several studies show about 1% dextrose and more than 0.2% lidocaine induced cell death in various cell types. We investigated the effects of low concentrations of dextrose and lidocaine in fibroblasts and suggest the optimal range of concentrations of dextrose and lidocaine in prolotherapy. Methods: Various concentrations of dextrose and lidocaine were treated in NIH-3T3. Viability was examined with trypan blue exclusion assay and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Migration assay was performed for measuring the motile activity. Extracellular signal-regulated kinase (Erk) activation and protein expression of collagen I and α-smooth muscle actin (α-SMA) were determined with western blot analysis. Results: The cell viability was decreased in concentrations of more than 5% dextrose and 0.1% lidocaine. However, in the concentrations 1% dextrose (D1) and 0.01% lidocaine (L0.01), fibroblasts proliferated mildly. The ability of migration in fibroblast was increased in the D1, L0.01, and D1 + L0.01 groups sequentially. D1 and L0.01 increased Erk activation and the expression of collagen I and α-SMA and D1 + L0.01 further increased. The inhibition of Erk activation suppressed fibroblast proliferation and the synthesis of collagen I. Conclusions: D1, L0.01, and the combination of D1 and L0.01 induced fibroblast proliferation and increased collagen I synthesis via Erk activation.

The beneficial effects of total parenteral nutrition (TPN) in improving the nutritional status of malnourished patients during hospital stays have been well established. However, recent randomized trials and meta-analyses have reported an increased rate of TPN-associated complications and mortality in critically ill patients. The increased risk of complications during TPN therapy has been linked to the development of hyperglycemia, especially during the first few days of TPN therapy. This retrospective study was conducted to determine whether the amount of dextrose from TPN in the 1st week in the intensive care unit (ICU) was related to the development of hyperglycemia and the clinical outcome. We included 88 non-diabetic critically ill patients who stayed in the medical ICU for more than two days. The subjects were 65 ${\pm}$ 16 years old, and the mean APACHE (Acute Physiology and Chronic Health Evaluation) II score upon admission was 20.9${\pm}$7.1. The subjects received 2.3${\pm}$1.4 g/kg/day of dextrose intravenously. We divided the subjects into two groups according to the mean blood glucose (BG) level during the 1st week of ICU stay: <140 mg/dl vs ${\geq}$ 140 mg/dl. Baseline BG and the amount of dextrose delivered via TPN were significantly higher in the hyperglycemia group than those in the normoglycemia group. Mortality was higher in the hyperglycemia group than in the normoglycemia group (42.4% vs 12.8%, P=0.008). The amount of dextrose from TPN was the only significant variable in the multiple linear regression analysis, which included age, APACHE II score, baseline blood glucose concentration and dextrose delivery via TPN as independent variables. We concluded that the amount of dextrose delivered via TPN might be associated with the development of hyperglycemia in critically ill patients without a history of diabetes mellitus. The amount of dextrose in TPN should be decided and adapted carefully to maintain blood glucose within the target range.

The effect of solubility and hygroscopicity of some tablet diluents on the disintegration of enzyme tablets was investigated. Tablets were prepared by direct compression method using sodium starch glycolate, crospovidone, croscarmellose sodium and low-substituted hydroxypropyl cellulose as super disintegrants. Lactose, dextrose, sucrose, sorbitol and calcium phosphate dibasic were selected as typical diluents in this study. They were different in solubility (sucrose, sorbitol>dextrose>dextrose>lactose>calcium phosphate dibasic) and hygroscopicity (sorbitol>sucrose>dextrose>caicium phosphate dibasic, lactose). The disintegrants accelerated differently the disintegration of the tablets prepared with different diluents in the decreasing order of calcium phosphate dibasic>lactose>dextrose>sucrose and sorbitol. These results indicate highly soluble and/or hygroscopic diluents decrease the efficiencies of super disintegrants in the enzyme tablets.

Purpose: Glucose has been recommended as an analgesic for mild to moderately painful procedures in neonates. The goal of this study was to assess the optimal dextrose concentration for pain control in newborns. Methods: This prospective, randomized, blinded clinical trial included 116 healthy full-term newborns. The neonates were randomly assigned to the following four groups by drawing straws: groups receiving sterile water or a 10%, 20%, or 40% dextrose solution orally. Each group was treated with the assigned solution prior to hepatitis B vaccination. The Neonatal Facial Coding System (NFCS) and the Neonatal Infant Pain Scale (NIPS) scores were evaluated before, immediately after, and 2 minutes after the injection in all neonates. Premature Infant Pain Profile (PIPP) scores were evaluated during the injection. All procedures were video-recorded, and pain scores were assessed by two independent observers who were not involved in the care of the newborns studied. The pain scores were compared among the four groups. Results: The 40% dextrose solution significantly reduced the NFCS (P=0.002) and the PIPP scores (P=0.001) compared with sterile water. No hyperglycemic events were noted in the study subjects 2 hours after the injection. Conclusion: The 40% dextrose solution effectively relieved pain due to intramuscular injection in full-term newborns without causing hyperglycemic events. However, the 10% and 20% dextrose solutions did not affect neonatal pain scores.

The expression kinetics of human lipocortin I (LCI), a potential anti-inflammatory agent, was studied in the shake-flask and fermenter cultures of Saccharomyces cerevisiae carrying a galactose-inducible expression system. The cell growth, expression level of LCI, and the plasmid stability were investigted under various galactose induction conditions. The expression of LCI was repressed by the presence of a very small amount of dextrose in the culture medium, but it was induced by galactose after dextrose became completely depleted. The optimal ratio of dextrose to galactose for lipocortin I production was found to be 1.0 (10 g/l dextrose and 10 g/l galactose). With optimal D/G ratio of 1.0 and the addition of galactose prior to dextrose depletion, LCI of about 100~130 mg/l was produced. LCI at a concentration of 174 mg/l was porduced in the fed-batch culture, which was nearly a twice as much of that produced in the batch culture. The plasmid stability was very high in all culture cases, and thus was considered to be not an important parameter in the expression of LCI.

Pathogenic E. coli associated post-weaning diarrhea (PWD) and edema disease are common diseases in commercially-housed weanling pigs. An enterotoxigenic E. coli (ETEC) oral challenge model has been used to mimic the physiological responses observed in commercial conditions. However, an oral challenge procedure has two major limitations: (1) the ETEC cell density is unknown at the point of oral inoculation, and (2) blending ETEC with traditional TSB (trypticase soy broth) is not palatable and hence decreases acceptability by piglets. Therefore, the purposes of this study were to (1) establish a regression equation that can be used for estimation of ETEC concentration in dilution media using the spectrophotometric measurement of cell density; and (2) examine survival of ETEC after blending either with TSB, sweetener or dextrose. A strain of ETEC (serogroup beta-hemolytic E. coli O149; K91; F4; toxins LT, STa, STb) was grown in TSB for 3.5 hours, centrifuged, the supernatant was discarded, and the ETEC pellet was then blended either with TSB (100 mL), sweetener (60 mL TSB + 40 mL fruit flavored concentrate), or dextrose (50 mL TSB + 50 mL dextrose; 0.5g/mL dextrose). Cell density was measured using the colorimetric method and also plated on a 5% sheep blood agar for counting of ETEC colony forming units at 0, 5, 35, 65 and 125 min after blending. The optical density at 600 nm explained 83% of ETEC colony forming units, indicating that the established linear equation (y= 6E+08x - 4E+07, P<0.004) can be used for robust quantification of ETEC cell density in TSB, sweetener and dextrose media. When ETEC was blended with sweetener and dextrose, survival of ETEC was decreased by 45% and 72% within 5 min post-blending. Therefore, further research is required to find out the suitable medium that has potential to improve palatability without compromising survival of ETEC.

Agrobacterium tumefaciens $A_4$T에 의해 형질전환된 사리풀 (Hyoscyamus niger L.)의 모상근으로부터 tropane alkaloids (scopolamine, hyoscyamine)의 생산성 향상을 위한 최적배지, 배양기간 및 탄수화물의 영향을 조사하였다. Tropane alkaloids의 생산성이 우수한 모상근 (HNl8, HN57)의 최적 배지는 SH배지이며, 모상근의 생장, tropane alkaloids 함량 및 생산성에서 조사한 6가지 배지보다 높게 나타났다. Tropane alkaloids생산을 위한 최적 배양기간은 HNl8 clone이 6주, HN57 clone은 5주로 나타났으며, 배양기간에 따라 scopolamine의 함량은 계속적으로 증가하는데 반하여 hyoscyamine의 함량은 일정 수준을 유지하는 것으로 나타났다. 두 세포주는 sucrose농도가 7%까지 증가할수록 생장률이 증가하는 반면, tropane alkaloids 함량은 감소하였으며, tropane alkaloids생산성은 3% sucrose처리구에서 가장 높게 나타났다. HN18 clone의 경우 최적 sucrose(3%)및 dextrose (2%)에서 유사한 tropane alkaloids 생산성을 나타내었다. 하지만 HN57 clone은 sucrose 처리구에 비하여 dextrose 처리구에서 매우 낮은 tropane alkaloids생산성을 나타내었다.

Background: Among the various pain-related diseases that can be encountered at the clinic, there is a neuropathic pain that is difficult to treat. Numerous methods have been proposed to treat neuropathic pain, such as taking medication, nerve block with lidocaine, or neurolysis with alcohol or phenol. Recently, a method of perineural injection using dextrose instead of lidocaine was proposed. This study was designed to compare the effects of perineural injection therapy (PIT) with buffered 5% dextrose or 0.5% lidocaine on neuropathic pain. Methods: The data were collected from the database of pain clinic from August 1st, 2019 to December 31st, 2022 without any personal information. The inclusion criteria were patients diagnosed with postherpetic neuralgia (PHN), trigeminal neuralgia (TN), complex regional pain syndrome (CRPS), or peripheral neuropathy (PN), and patients who had undergone PIT with buffered 5% dextrose (Dextrose group) or 0.5% lidocaine (Lidocaine group) for pain control. The data of patients, namely sex, age, and pain score (numerical rating scale, NRS) were collected before PIT. The data of NRS, side effects, and satisfaction grade (excellent, good, fair, or poor) were collected one week after each of the four PIT, and two weeks after the last PIT. Results: Overall, 112 subjects were enrolled. The Dextrose group included 89 and Lidocaine group included 23 patients. Because the number of patients in the Lidocaine group was too small to allow statistical analysis, the trend in Lidocaine group was just observed in each disease. There were no significant side effects except for a few bruise cases on the site of injection in all groups. The NRS in most Dextrose groups except CRPS were reduced significantly; however, the Lidocaine group showed a trend of pain reduction only in PHN. The Dextrose group except CRPS showed increased satisfaction two weeks after the final PIT. Conclusion: From the results, it is suggested that PIT with buffered 5% dextrose may have a good effect for neuropathic pain without any side effect except for patients with CRPS. This may offer a window into a new tool that practitioners can employ in their quest to help patients with neuropathic pain.

Effects of water soluble carrier on the dissolution characteristics of indomethacin coprecipitates were investigated. Water soluble carriers used were polyvinylpyrrolidone, dextrose, mannitol and their mixtures of various ratios. The dissolution rates of indomethacin from coprecipitate with ratios of drug-to-carrier, kinds of carrier and ratios of carriers were as follows: 1. The dissolution rates increased proportionally to the ratios of carrier in the case of both single and combined carrier, and the dissolution rate of coprecipitate with the combined carrier was more rapid than that with single carrier. 2. The combined carrier of PVP-dextrose (1 : 2) in the case of the coprecipitate of drug-to carrier (1 : 1) and PVP-dextrose (4 : 1) in the case of the coprecipitate of drug-to carrier (1 : 3) yield the most rapid dissolution rate. 3. The dissolution rate of indomethacin was the most markedly enhanced in the case of the combined carrier of PVP and dextrose.
