Purpose: This study was to evaluate the effects of Aloe. Gelfoam. and Plaster of Paris on bone healing. Materials and Methods: Four experimental defects were created for placement of the three materials in the right femur of dogs. One defect served as an empty control site. The evaluation was performed at 1-. 6-. and 12-weeks by light microscopy and radiographs. Results: Radiographic and histologic examinations showed new bone formation in the presence of Aloe, Gelfoam. and Plaster of Paris and similar bone healing reactions. Conclusion: On the basis of these findings, it was concluded that Aloe, Gelfoam. and Plaster of Paris may be adequate agents for use in bone procurement.

In the course of evaluation of hepatoprotective components against alcohol-induced toxicity from Aloe spp., the methanol extract was found to cause a significant inhibition of rat liver cytosolic alcohol dehydrogenase activity. Systematic fractionation of active tractions monitored by bioassay led to isolation of four compounds; aloe-emodin, aloenin, ethylidene-aloenin and ${\beta}-sitosterol$, which were estimated as active principles for inhibition of c-ADH and c-ALDH activities in vitro.

The contents of aloesin in aloe preparations were determined by HPLC. Aloesin was extracted 3 times with ethanol for 30 minutes. The ethanol extract was concentrated and suspend ed in saturated NaCl aqueous solution and successively partitioned with dichloromethane, n-butanol. Prepared samples were analyzed by HPLC on a reverse column(Inertsil ODS-2). In assay, internal standard was a puerarin and regression of calibration curve was 0.998. Recoveries of aloesin added to aloe preparation were 98~123(%).

The effects of aloe on the MDA(malondialdehyde) and the blood biochemical components of heavy metal poisoning in SD rat were examined and the following results were obtained. In rat liver homogenate intoxicated with $CdCl_2$, lipidperoxide was increased each 2.37times(24h), 3.31times(72h) but lipidperoxide In aloe administration groups was lower each 47% , 64% than in heavy metal group. In rat kidney homo- genate intoxicated with $CdCl_2$, lipidperoxide was increased 1.85times(24h), 1.33times(72h) but lipidperoxide in groups was almost the same as that of normal group. Lipidperoxide of kidney homogenate was slightly decreased as time passed. Also heavy metal poisoning rats showed high levels(1.38-2.50times) of serum AST, ALT and BUN. However. the administration of aloe significantly inhibited the reduction of them. These results suggest that Cd-induced hepatic and renal injury, via increase llpidpero)Ode and release of AST, ALT and BUN. Aloe may be used to inhibit or prevent the hepatic and renal toxicity which results from the heavy metal.

The purpose of this study was to develop the antiallergic and hypoallergic fennented soybean foods without side effect. We manufactured Chungkukjang with addition of herbal (aloe, cinamon, licorice root) extract. Sensory evaluation was performed to evaluate the acceptability by the consumer. Clinical evaluation was performed with 10 atopic dermatitis (AD) patients who showed positive reaction with specific IgE and skin prick test. Cross-over study between nonnal Chungkukjang and Chungkukjang with aloe extract was performed. In sensory evaluation, Chungkukjang with aloe extract obtained best score overall. In clinical evaluation, 7 out of 10 AD patients showed positive reaction to soy-bean and 4 out of 10 AD patients showed positive reaction to normal Chungkukjang. 2 out of 10 AD patients showed positive reaction to Chungkukjang with aloe extract. In conclusion, Chungkukjang could be recommended as functional food with hypoallergic effect. As adding aloe extract to Chungkukjang, hypo allergic effect was increased.

Multidrug-resistant Acinetobacter baumannii and Pseudomonas aeruginosa are highly dangerous nosocomial pathogens, cause the symptoms of skin infections, pressure sores, sepsis, blood stream and wound infections. Unfortunately, these pathogens are immune to the most common antibiotics, such as, carbapenem, aminoglycoside and fluoroquinolone. Therefore, it is imperative that new and effective antibiotics be developed. In the present study, the antimicrobial effects of Aloe vera MAP (modified Aloe polysaccharide) on Staphylococcus aureus and Bacillus subtilis, Escherichia coli and Enterobacter aerogenes, and clinical Pseudomonas aeruginosa and clinical Acinetobacter baumannii were comprehensibly investigated. Prior to the growth inhibition effect measurement and antibiotic disc diffusion assay on gram-positive and gram-negative bacteria and selected multidrug-resistant Pseudomonas aeruginosa and Acinetobacter baumannii, antimicrobial resistance screening was performed for the multidrug-resistant bacteria obtained from clinical isolates. The results for showed the Aloe vera MAP had a concentration-dependent effect on all of examined bacteria, particularly on Pseudomonas aeruginosa. Anti-inflammatory and anti-oxidant experiments were also performed dose dependently effects to confirm the beneficial physiological effects of Aloe vera MAP.

Aloe, being used widely as a health food and also as a traditional folk remedy for burns and constipation, contains quinone derivatives particularly in its skin. Thus, we have investigated the effect of extracts of Aloe in ethanol metabolism. The dried powder of water extract of skinned Aloe (300 mg/kg body weight given to rats by oral adminstration at 30 min prior to oral adminstration of ethanol given at a does of 4 gm/kg) and the freeze-dried Aloe gel commercial product (600 mg/kg) which was prepared after selective elimination of quinones were found not to increase the ethanol metabolism rate in vivo. This result suggested that quinones, missing from the above preparations, might be responsible for enhancing ethanol metabolism rate.

Obesity-induced disorders contribute to the development of metabolic diseases such as insulin resistance, fatty liver diseases, and type 2 diabetes (T2D). In this study, we evaluated whether the Aloe QDM complex could improve metabolic disorders related to blood glucose levels and insulin resistance. Male C57BL/6 obese mice fed a high-fat diet for 54 days received a supplement of Aloe QDM complex or pioglitazone (PGZ) or metformin (Met) and were compared with unsupplemented controls (high-fat diet; HFD) or mice fed a regular diet (RD). RT-PCR and western blot analysis were used to quantify the expression of obesity-induced inflammation. Dietary Aloe QDM complex lowered body weight, fasting blood glucose, plasma insulin, and leptin levels, and markedly reduced the impairment of glucose tolerance in obese mice. Also, Aloe QDM complex significantly enhanced plasma adiponectin levels and insulin sensitivity via AMPK activity in muscles. At the same time, Aloe QDM decreased the mRNA and protein of $PPAR{\gamma}/LXR{\alpha}$ and scavenger receptors in white adipose tissue (WAT). Dietary Aloe QDM complex reduces obesity-induced glucose tolerance not only by suppressing $PPAR{\gamma}/LXR{\alpha}$ but also by enhancing AMPK activity in the WAT and muscles, both of which are important peripheral tissues affecting insulin resistance. The Aloe QDM complex could be used as a nutritional intervention against T2D.

This study was carried out to investigate the in vitro and in vivo moisturizing properties and percutaneous absorption of PEG-impregnated Aloe vera gel. The PEG-i-Aloe gel was obtained from dewatering and impregnation by soaking (DIS) of Aloe vera leaf slice. The moisturizing property of the obtained sample was evaluated by moisture determination using gravimetric method in desiccator under different RH% and by water sorption-desorption test on human skin. The transdermal penetration characteristics of PEG-i-Aloe gel was investigated by Franz diffusion cell in vitro transdermal absorption method. PEG-i-Aloe gel had high moisture retention ability and could significantly lead the enhancing skin hydration status as well as reducing the skin water loss due to the film formation as a skin barrier. The skin penetration rate of PEGi- Aloe gel at steady state was 9.76 ${\mu}g/(h{\cdot}cm^2)$ and the quantity of the transdermal absorption was 144 ${\mu}g/cm^2$ in 9 hr. The penetration mechanism was well fitted with Higuchi model ($R^2$ = 0.974-0.994). The results show that PEG-i-Aloe gel has the significant moisturizing effect and strong penetration of the animal skin. It could be used as the moisturizing additive in cosmetic skin products.
