Sulfate 염과 Sulfonate 염의 활성능에 관한 비교시험

최영숙 한국약제학회 1980 Journal of Pharmaceutical Investigation Vol.10 No.3

This study was performed to compare the activities of sulfate esters and sulfonate salts. (comparison of activities such as detergency, forming, permeation and patient of hard water). The one of the method is the combined use of nonionics and the other is the use of anionics alone. The results obtained are as follows: 1. The sulfonate salts are better soluble than the sulfate esters. 2. The lauryl system is better soluble than the sulfate esters. 3. The alkylol sulfate (CONH-OSO₃H) that is induced amide radical to the fatty acid shows the excellent foaming power and detergency.

懸濁化濟가 Suspension에 미치는 影響

崔英淑 水原大學校 1984 論文集 Vol.2 No.-

It is very important to select the suspending agent on making suspension. After adding the two kinds of suspending agents(bentonite, C.M.C-Na) into a Calamine Suspension, we discussed the phenomena of sedimentation in each case and compared them with each other. In Calamine Suspension, the type of sedimentation was not altered by the change of the size of particle, and the Specific Sedimentation Volume was smaller when the size of particle was larger. Both the type of sedimentation and the Specific Sedimentation Volume of Calamine Suspension were different respectively according to the different kinds and concentrations of suspending agents. The types of sedimentation were divided into the Free Sedimentation and the Collective Sedimentation. We got the favorable results for the Specific Sedimentation Volume and the Sedimentation Volume when we added the 4%(w/v) bentonite or 1.5% C.M.C.-Na as the suspending agents.

With the rapid industrial development it has been necessitated that we should place more emphasis on the consumer aspect of our home life. Some problems in consumer life have been investigated and the importance of consumer education in home economics education in the primary-and the secondary-school has been stressed.

This study was carries out on 47 persons (23-79yr) of female farmers to determine the blood contents. Their mean age was 51 years old. The mean values of Pi, Ca, Mg, Na, K, Cu and Zn in serum of subjects were 3.6±0.9mg/100ml, 9.0±0.3mg/100ml, 1.9±0.1mg/100ml, 141.9±1.9mM/1, 4.2±0.5mM/l, 99.5±92.4ug/100ml and 95.7±48.4ug/100ml.

Rutin inhibits DRP1-mediated mitochondrial fission and prevents ethanol-induced hepatotoxicity in HepG2 cells and zebrafish

Excessive alcohol consumption causes the cellular and tissue damage. The toxic metabolites of ethanol are harmful to multiple organ systems, such as the central nervous system, skeletal muscles, and liver, and cause alcohol-induced diseases like cancer, as well as induce hepatotoxicity, and alcoholic myopathy. Alcohol exposure leads to a surge in hepatic alcohol metabolism and oxygen consumption, a decrease in hepatic ATP, and the rapid accumulation of lipid within hepatocytes. Several pathologies are closely linked to defective mitochondrial dynamics triggered by abnormal mitochondrial function and cellular homeostasis, raising the possibility that novel drugs targeting mitochondrial dynamics may have therapeutic potential in restoring cellular homeostasis in ethanol-induced hepatotoxicity. Rutin is a phytochemical polyphenol known to protect cells from cytotoxic chemicals. We investigated the effects of rutin on mitochondrial dynamics induced by ethanol. We found that rutin enhances mitochondrial dynamics by suppressing mitochondrial fission and restoring the balance of the mitochondrial dynamics. Mitochondrial elongation following rutin treatment of ethanol exposed cells was accompanied by reduced DRP1 expression. These data suggest that rutin plays an important role in remodeling of mitochondrial dynamics to alleviate hepatic steatosis and enhance mitochondrial function and cell viability

Background: Osteoporosis leads to a reduction in absolute bone volume and results when bone loss is sufficient to cause increased risk of fracture. The combination of bone turnover markers and bone mineral density(BMD) evaluation is helpful in identifying patients at risk of osteoporosis, especially perimenopausal women, who should be offered early preventive treatment before appreciable bone loss occurs. Methods: The authors measured serum osteocalcin levels as a bone formation marker. urinary N-telopeptide of type 1 collagen(NTx) levels as a bone resorption marker, and checked lumbar spine BMD in 50 women for health examination. Osteocalcin, NTx and BMD levels were analysed according to age. Bone turnover markers were compared with BMD. These bone turnover markers were compared with each other. Results : Osteocalcin and NTx levels correlated significantly with each other. These biochemical bone markers were higher in women after 49 years than before 48 years. These markers decreased after seventh decades, but these values showed more increased levels than before 48 years. BMD decreased with age. Blochemical bone markers and BMD showed negative correlations. Conclusion : Osteocalcin and NTx levels show significant difference between premenopausal and postmenopausal women. Bone resorption marker is more or less responsive to changes in bone metabolism than bone formation marker. The authors suggest a woman who has normal bone mass but is a fast-loser with increased bone resorption may be at greater risk for subsequent osteoporosis than a woman who has a lower bone mass but who is a slow-loser.

Phosphate Builders가 界面活性劑의 洗淨效果에 미치는 影響

崔英淑 水原大學校 1983 論文集 Vol.1 No.-

The detergency effects of phosphates with varying degree of concentration in surfactant solution, soap and sodium lauryl sulfate on different fabric materials, cotton, polyester, and wool investigated in this experiment. The removal efficiencies of phosphate concentration in sodium lauryl sulfate solution were proved better than soap solution and the best result was achieved at 20% phosphate concentration in both solutions. In standard soil state, sodium tripolyphosphate in both surfactant solutions was more effective for cotton material than sodium pyrophosphate, but sodium pyrophosphate was more effective for polyester material than sodium tripolyphosphate. In liquid paraffin soil state, sodium tripolyphosphate in soap solution was the most effective of all phosphates for three fabrics, but sodium pyrophosphate in sodium lauryl sulfate solution was more effective for cotton and polyester material than other phosphates, however, sodium tripolyphosphate in sodium lauryl sulfate solution was shown effective in wool material only.
