The effects of aloe on liver function and lipid metabolic disorders induced by alcohol consumption were studied in rats using aloe power (0.25%, 0.5%, 1%) and 10% ethanol. 35 Sprague-Dawley (male, 4 weeks old) rats were divided into five groups and fed experimental diets for six weeks. Body weights of rats tended to be lower in all alcohol supplemented groups than in the control. Food intakes and dry feces per day were significantly lower in all alcohol supplemented groups than in the control. Atherogenic indices (AI) were highest in the alcohol group and decreased in proportion with aloe amount. Serum triglyceride level was significantly higher in the alcohol group than in the control, but tended to be lower in the aloe supplemented groups. In relation to liver function, glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), and alkaline phosphatase (ALP) activities tended to be higher in the alcohol groups than in the control, but lower in the aloe groups, especially in the alcohol+0.5% AO group. The levels of liver cholesterol were significantly lower in the alcohol group than in the control and aloe supplemented groups. In the histochemical evaluation, fat droplets appeared extensively on the liver-lobule in the alcohol group, whereas they decreased slightly in the alcohol+0.25% AO group and apparently disappeared in the alcohol +0.5% AO. On the other hand, fat droplets appeared again on the liver-lobule in the alcohol+1% AO group, but were reduced compared with the alcohol group. Regarding the fatty acid composition of adipose tissue triglycerides, the level of linoleic acid (18:2) was significantly higher in the aloe supplemented group. Regarding the fatty acid composition of liver phosphatidylcholine (PC), the level of linoleic acid was higher in the alcohol group and alcohol+1% AO group than the other groups. In contrast, the level of arachidonic acid was significantly lower in the alcohol group. As a result, arachidonic / linoleic acid ratios were significantly lower in the alcohol group compared to the control group, whereas the ratios of the aloe supplemented groups were similar to that of the control group. Therefore, aloe had some beneficial effects on lipid metabolic disorders induced by alcohol and affected desaturation of fatty acids.
Present study aimed to investigate the radioprotective effects of propolis feeding on rat tissues damaged by X-ray irradiation. It was shown that the number of white blood cell in X-ray irradiated group supplemented with propolis increased as much to those of the control group and also the GOT activities among the blood components were decreased after propolis feeding. The mineral contents such as Mg, Fe, Ca, Mn, Cu, Mo, Ni, As in liver were increased as compared with those of the control group but maintained lower level than those of only irradiated groups, implying that the propolis feeding elevated the recovery capability of white blood cell effectively and propolis have a potential resistance to cell damage by X-ray. According to histological observations of the testis, intestine and liver tissues which are irradiated after feeding propolis, the numbers of damaged undifferentiated cells were decreased in testis and the shape of the goblet cells and inner and outer muscular layers in intestine were restored to the original state and the hepatocytes and interlobular veins were shown intact in liver, suggesting that propolis has a potential capacity to restore cell shapes or resist deformation of cell.

The Clinical Study on the Body Weight Loss of Taeumin Inpatients in Stroke by Sasang Constitutional Medicinal Treatment. Purpose: It has been frequently noted that overweight and obesity have a stronger relationship to hypertension and diabetes mellitus than to the risk of stroke. The purpose of this study is to find out whether Sasang Constitutional Medicinal treatment in the stroke patients of Tae-um-in has an effect on local or general weight loss. Methods: Case-control study was applied. The experiment group is the 24 Taeumin stroke inpatients who were in hospital in Kyung-Hee Oriental Hospital from July 1, 2000 to October 1 and received Sasang Constitutional Medicinal treatment. The control group is the 13 Taeumin stroke inpatients who were in the hospital during the same period but didn't receive Sasang Constitutional Medicinal treatment. In the two groups, body weight, BMI, the skin fold(cm) of triceps, suprailiac, abdominal portion, and thigh and the circumference(cm) of wrist, biceps, triceps, and W/H ratio were compared and studied for three weeks. Results: 1. In the experiment group, there were 8 women and 15 men, 23 in total and in the control group, there were 5 women and 9 men, 14 in total. 2. From two weeks later, there was a significant decrease in the experiment group in weight loss, the ratio of loss, and BMI(p<0.05). 3. Concerned with the change in the skin fold of suprailiac portion, there was a significant decrease in each group(p<0.05). 4. Concerned with the change in the skin fold of Chunchu-Hyel portion(天樞穴), thigh and in the circumference of hip, W/H ratio, there was a significant decrease in the experiment group(p<0.05). 5. Concerned with the change in the value of Lipid Profile, GOT, and GPT, only Glucose(GLU) showed a significant decrease(p<0.05) in the experiment group(p<0.05). As Conclusion, Sasang Constitutional Medicinal treatment in the stroke patients of Tae-um-in has an effect on local or general weight loss.

Effects of wild plant extract (Lak) based on Korea traditional prescription on maximal exercise performance and endurance were evaluated using calorie-restriction animal model. In acute forced swimming test with 10% body weight attached to tail, dietary Lak supplementation increased exercise performance endurance by increasing concentrations of ATP and insulin-like growth factor-1 (IGF-1) under calorie-restriction condition, and decrement of blood lactic acid concentration and increment of muscle ATP content were observed. These results suggest Lak is very effective for decreasing side-effects of obesity therapy using very low calorie diet.
The effect of methanol extract from Agaricus blazei Murill on the hepatotoxicity was investigated $CCl_4$ is one of the oldest and most widely used toxins for the induction of hepatic damages and fibrosis in experimental animals. In this study, male Sprague-Dawley(SD) rats were randomly divided into 6 groups of the control(C), $CCl_4(T),\;CCl_4$ and high fat group(TL) with matching sub-groups of Agaricus blazei Murill extract-fed groups of CA, TA and TLA. Methanol extracts of Agaricus blazei Murill were fed 50 mg/kg B.W daily via drinking water. A 1.2 mL of $CCl_4/kg$ body weight was administered by oral intubation twice a week for total of six times. The levels of total-cholesterol, TG, LDL and LDL-phospholipids were elevated by $CCl_4$ treatment as compared to the control(C). However, Agaricus blazei Murill methanol extract feeding in the group of TA and TLA significantly(p<0.05) decreased TG by 53.1 % and 17.9% compared to the internal control of T and TL, respectively. Triglyceride of TL was increased by 3.33 times(p<0.05) compared to the control(C) with $CCl_4$ and high fat administration from 3.78 mg/g to 12.60 mg/g liver. The extract(CA) also reduced kidney weight compared to the control(C). With the administration of high fat and $CCl_4$(TLA), the extract reduced the organ weight of both liver and kidney and further, significantly reduced TG, total cholesterol and GTP activity. Hepatoprotective effects of Agaricus blazei Murill on GOT, GPT, AP and LDH activities were enhanced by the extract feeding. Electronmicrograph showed that $CCl_4$ deteriorated the structure of cytoplasmic matrix with its uneven distribution. However, the extract reconstituted the damaged cytoplasm and stimulated mitochondriogenesis. The above results suggest that Agaricus blazei Murill may have a possible protective effect against chemically induced liver damage and further help to reduce the symptoms of fatty liver.

This study aimed to verify the effect of Citrus unshiu peel water extract (CUP) on a mouse model of acute gastritis (AG) induced by HCl/ethanol. Several studies have found that CUP has anti-inflammatory effects. The AG model was induced by oral administration of 150 mM HCl/60% ethanol (550 µL) to all groups except the control group. Also, for drug treatment, sucralfate (10 mg/kg) and CUP (100 or 200 mg/kg) were orally administered for 90 minutes before induction. The effect of CUP treatment was confirmed by gross gastric mucosal damage measurement, and the levels of Glutamic Oxaloacetic Transaminase (GOT), Glutamic Pyruvic Transaminase (GPT), and myeloperoxidase were reduced as well as the levels of oxidative stress biomarkers and their related proteins. In addition, the levels of inflammatory proteins, mediators, and cytokines were significantly downregulated byPI3K/Akt signaling. Taken together, these results show that CUP treatment alleviates AG by regulating PI3K/Akt signaling.

Phellinus linteus (PL) has been known to exhibit potent biological activity. The present study was designed to investigate lipase-inhibitory and anti-oxidative activity of the methanol extract and the powder of PL fruiting body. The methanol extract of PL appeared to have the inhibitory activity against pancreatic lipase with an $IC_{50}$ value of $36.3\;{\mu}g/mL$, and the scavenging activity of DPPH radical with an $IC_{50}$ value of $20.1\;{\mu}g/mL$, which was similar to that of vitamin C ($IC_{50}\;18.3\;{\mu}g/mL$). To investigate the lipase-inhibitory and anti-oxidative effect of PL on animal, Sprague-Dawley rats were fed with high-fat diet supplemented with either 2% or 5% PL powder for 8 weeks. Total food intake was significantly increased, but body weight was not changed by PL powder supplementation. However, fecal fat excretion of the experimental groups fed with the PL powder were higher than that of the control group. PL powder showed a decrease in the plasma total cholesterol, LDL-cholesterol, and the hepatic total cholesterol levels. The anti-oxidative enzyme activities were also affected by PL supplementation. Glutathione peroxidase (GSH-Px) in the plasma and liver were significantly increased by 98% and 46% in the 2% PL group, and 99% and 32% in the 5% PL group, respectively. Total superoxide dismutase (T-SOD) activity was not affected by PL supplementation. DNA damage was measured by the comet assay in the lymphocytes collected after 2 weeks, 4 weeks, and 8 weeks of feeding PL supplemented diet. Lymphocyte DNA damage was decreased in the PL supplemented group. Furthermore, PL feeding enhanced the resistance to lymphocyte DNA damage caused by an oxidant challenge with $H_2O_2$.
Pokeweed, a polycarpic plant, has been used as herbage medicine, vegetable or dye. It, however, is known as an aggressive plant in the vicinity of the industrial area evolving air pollutants. The experiment was done to determine the effect of priming using nitrates, germination temperature and light quality on germination of its seed to get information on the optimum germination process as well as its establishment. The daily percent germination was measured to 12 days after sowing since its seeds were treated by two different nitrates [KNO$_3$, Ca(NO$_3$)$_2$]. their different concentrations (0, 50, 150, 300mM), then treatment duration (1, 3, 6 days), different germination temperature (day /night; 30/30, 30/20, 20/30, 20/2$0^{\circ}C$) and light quality (red, white, dark) before or during germination. The percent germination was greater in the KNO$_3$ treatment than in the Ca(NO$_3$)$_2$ but in the priming treatment with KNO$_3$ in comparison with no-priming. In the priming treatment with KNO$_3$, the percent germination was increased with its increased concentration to 150mM although decreased with delayed duration to 6 days. Regardless of light quality, the greater percent germination was shown in the order of 2$0^{\circ}C$ constant and 20/3$0^{\circ}C$ alternative, 3$0^{\circ}C$ constant, 30/2$0^{\circ}C$ alternative temperature. The germination was less in the dark during germination than in the illumination in which the red light had greater percent germination compared to white light. The seeds primed with KNO$_3$ were germinated under the alternative temperature even in the dark condition.
The strains were added to the feed in the concentration of $10^3$, $10^5$, and $10^7$ CFU/kg and 2% of fishes were given the feed twice a day (8 AM and 5 PM) for 12 weeks. In result of the nonspecific immune response study to examine Respiratory burst activity, Lysozyme activity and Phagocytosis activity every two weeks until the end of the study, all test samples showed greater activities than control samples and improved immune activity with Bacillus sp. IS-2. The mortality test performed by artificial infection using Streptococcus iniae, a pathogenic bacterium, after the completion of this study also showed over 55% greater survival rate in all test samples. In result of performing PCR using the universal primer to verify that the probiotic stays in the intestines of the fishes, all test samples showed PCR product of 1,465 bp. Based on the above findings, it was concluded that Bacillus sp. IS-2 in the feed improved farmed flatfish's immune system and resistance against diseases as the probiotics. Also, the physiological indicators discovered by this study would be useful for identifying the mechanisms of probiotics.
