In order to study the effects of Aloe vera Linne treatment on the clinical chemistry in patients with liver disease, seven patients were administered orally with 800~1, 600 mg of Aloe vera Linne four times day for six months. The high levels of serum AST, ALT, ALP, ${\gamma}$-GTP and total bilirubin in patients were significantly reduced by adminstration of Aloe vera L. The reduced serum albumin/globulin value was increased by Aloe vera L. treatment. But other blood parameters of clinical chemistry values were not affected by Aloe vera L. treatment. These data suggest that Aloe vera L. can be effective in treatment of the patients with liver disease.

For the purpose of screening the functionality in aloe, the mucilage from Aloe vera Linne was prepared by extraction of mucilaginous parenchyma with ethanol followed homogenation, filtration and centrifigation. Flocculability of this mucilage from Aloe vera L. was investigated and the identification fro flocculating active materials were carried out. The mucilage exhibited an excellent flocculability for 1% bentonite and 5,000 ppm kaolin suspensions. The good correlations between mucilage volume(concentration) and flocculability for 1% bentonite suspension were obtained. The flocculated volume or flocculation rate was affected depending upon the degrees of processing such as a heat treatment and purification. A major component showing the flocculaing activity was considered as a highly polymerized polysaccharide having flocculating activity was about 1,000,000 daltons.

The antioxidant capacity of aloe vera gel (AG), aloe vera exudates (AE), and a low molecular filtrate of aloe vera gel (ALMF) prepared from aloe vera grown on Jeju Island, Korea was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azinobis-3-ethyl-benzothiazoline-6-sulfonic acid (ABTS), and oxygen radical absorbance capacity (ORAC) assays, and total phenolic content (TPC), and total flavonoid content (TFC) were determined. The phenolic compounds in aloe samples were analyzed. Antioxidant capacities in oil-in-water emulsions following riboflavin photosensitization were analyzed using lipid hydroperoxide. AE had significantly higher antioxidant capacity than that of the other samples based on the DPPH, ABTS, and ORAC assays (p<0.05). Lipid hydroperoxide values of 5 mg/mL for AG, AE, and ALMF were 521.78, 272.32, and 699.89 mmol/kg oil, respectively, whereas that of samples without aloe vera was 893.07 mmol/kg oil over 48 h. AE had higher TPC and TFC values. Aloesin and aloin were found in AE, whereas those compounds were only found in trace amounts in AG and ALMF.

Aloe(Aloe vera LINNE) has been used as a home medicine for the past several thousand in the world, and has been studied on various chronic degenerative diseases such as atherosclerosis, myocardiac infarction and hypertension. SMAP8, learning and memory impairment animal mode, were fed basic or experimental diets with 1.0% of freeze dried(FD)-Aloe powder for 8 months. This study was designed to investigate the effects of Aloe on body weight gain, grading score of senescence(GSS), triglyceride, total and LDL-cholesterol levels, and atherogenic index in serum of SAMP8, and also designed to investigate the effects of Aloe on cholesterol accumultions in mitochondria and microsome fractions of SAMP8 brain. Body weight gain was consistently lower in aloe group than in control group, but no significantly differences between them. Grading score of senescence resulted ina marked decreases pf 20% in 1.0% Aloe group compared with control group. Administrations of 1.0% aloe resulted ina marked decreases in 15% and 20% of triglyceride and cholesterol levels, respectively, and also significantly decreased in 15% of LDL-cholesterol levels and atherogenic index in serum of SAMP8 compared with control group. Cholesterol accumulations were significantly inhibited in 20% and 10% of mitochondria and microsome fractions of SAMP8 brain, respectively, by administration of 1.0% Aloe. These results suggest that administration of Aloe mau not only effectively inhibit chronic degenerative diseases in serum of SAMP8, but may also improve learning and memory impairments of SAMP8 brain.

제주도에서 많이 생산되고 있는 톳과 알로에를 초임계이산화탄소와 보조용매로서 에탄올로 추출하여 각각의 추출수율을 측정하고, 이들 추출물들의 항균활성을 검색하였다. 추출용매로 초임계이산화탄소-에탄올을 병용했을 때 톳과 알로에의 추출수율과 용해도는 초임계이산화탄소만을 사용했을 때보다 2배 이상 높았다. 모든 추출물들은 Escherichia coli, Bacillus subtilis, Saccharomyces cerevisiae 그리고 Alternaria sp.에 대하여 항균활성을 보였는데, 세균에 대하여 가장 높고, 그 다음 효모, 곰팡이 순이었다. 초임계이산화탄소-에탄올 추출물에는 초임계이산화탄소만을 사용한 추출물에 비하여 2배 이상의 고형물이 함유되어 있었음에도 불구하고, 두 종류의 추출물이 거의 동일한 항균활성을 나타낸 것으로 보아, 초임계이산화탄소와 같은 비극성용매에 용해되는 물질들이 보다 강한 항균성을 보이고 있는 것으로 추정된다.

The quality characteristics of breads made by adding levels of 30%, 60%, and 100% aloe gel were investigated. The 60% aloe gel sample had a larger dough volume than the control dough. Also, the loaf volume and specific volume of the bread made with 60% aloe gel were larger than those of the control bread. The pasting temperature increased gradually with the increasing amounts of substituted aloe gel as compared to wheat flour with water added$(66.5{\pm}12^{\circ}C)$; the wheat flour with 100% aloe gel had a pasting temperature of $90.7{\pm}1.1^{\circ}C$. Peak viscosity decreased gradually with increasing amounts of aloe gel when compared to the wheat flour with water added. Setback also was decreased gradually with the increasing amounts of aloe gel as compared to the wheat flour with added water. From the setback decrease it is suggested that the aloe controlled retrogradation of the bread during short-term storage. The crumb color of the bread made with the aloe gel was not significantly different to that of the control bread, and the color of the crumb was yellow-white. Bread hardness decreased gradually with increasing amounts of the substituted aloe gel. However, bread gumminess and chewiness increased gradually with increasing amounts of aloe gel. The springiness of the bread made with 100% aloe gel was lower than that of the control bread. With regard to flavor and taste, the bread made with 100% aloe gel produced a green-like odor and had a bitter taste. The mouth feel of the breads made with aloe gel was considered soft and moist. The overall acceptabilities of the breads made with 30% and 60% aloe gel were not significantly different from the control bread, but the bread made with 100% aloe gel had a green smell and bitter taste. Yet accordingly, the results indicate that functional and health products with improved quality could be developed by adding aloe gel to breads and cakes.

Leaves of Aloe vera Linne and bloods of domestic animal were composted in a soild state fermentation reactor (SSFR) by using microbial additive including a bulking and moisture controlling agent. From solid-culture of microbial additive, 10 species of bacteria and 10 species of fungi were isolated and, their enzyme activities including amylase, carboxy methyl cellulase CMCase, lipase and protease were detected. Optimum fermentation conditions of Aloe leaves and domestic animal bloods in SSFR were obtained from the studies of response surface analysis employing microbial additive content, initial moisture content, and fermentation temperature as the independent variables. The optimum conditions for SSFR using Aloe leaves were obtained at 9.45$\pm$73%(w/w) of microbial additives, 62.73$\pm$4.54%(w/w) of initial moisture content and 55.32$\pm$3.14$^{\circ}C$ of fermentation temperature while those for SSFR using domestic animal bloods were obtained at 10.25$\pm$2.04%, 58.68$\pm$4.97% and 57.85$\pm$5.$65^{\circ}C$, respectively. Composting process in SSFR was initially proceeded through fermentation and solid materials were decomposed within 24 hours by maintaining higher moisture level, and maturing and drying steps are followed later. After the fermentation step, the concentrations of solid phase inorganic components were increased while that of organic components were decreased. Also, concentrations of total organic carbon(TOC), peptides, amino acids, polysaccharides, and low fatty acids in water extracts were increased. As fermentation in composting process depends on initial C/N ratios in water extracts of two samples were increased because of increased water-soluble TOC. From these results, it was revealed that solid state fermentation reactor using microbial additives can be used in composting process of organic wastes with broad C/N ratio.

Objective : In this study, we investigated the effect of SAL5(mixing extracts of Schisandra chinensis Baillon, Artemisia capillaris Thunb., and Aloe vera Linne) on chronic ethanol-induced fatty liver model. Methods : Sprague-Dawley male rats were fed Liber-DeCarli (normal), ethanol liquid diet (control), SAL5 (200 mg/kg). We administrated the SAL5 on chronic ethanol-induced fatty liver model for 5 weeks. We measured alkaline phosphtase (ALP), alanine transminase (ALT), aspartate transminase (AST) and ${\gamma}-glutamyl$ transpeptase (${\gamma}-GTP$) in serum and triglyceride (TG), superoxide dismutase (SOD), catalase, glutathione (GSH) and malondialdehyde (MDA) level in liver. Liver histopathology was examined by Hematoxylin-eosin and Oil red O staining of the fixed liver tissues. Real-time PCR was performed to measure the mRNA expression of inflammatory cytokines and MMP-2, MMP-9. Results : SAL5 administration resulted in significantly decreased liver marker enzymes activities of alanine transminase (ALT), ${\gamma}-glutamyl$ transpeptase (${\gamma}-GTP$) in serum and triglyceride (TG) activities in liver. The control group decreased the activities of superoxide dismutase (SOD), catalase (CAT) with the reduced level of glutathione (GSH) in liver. On the other hand, SAL5 group increased the activities of SOD, CAT and the level of GSH. SAL5 delayed the development of an alcoholic fatty liver by reversing fat accumulation in the liver, as evidenced in histological observations. The gene expression of mRNA were significantly decreased at the $IL-1{\beta}$, $TNF-{\alpha}$, NOS-II and MMP-2 by SAL5. Conclusions : These results indicate that SAL5 might have protective effect chronic ethanol-induced fatty liver models.
