This study was conducted to investigate the dietary supplementation of fruiting body of Hericium erinaceus (HE) mushroom on lipid profiles of serum and histological changes of the liver in rats with high fat and cholesterol diet. Five-week old female Sprague-Dawley albino rats were divided into three groups of 8 rats each: The normal control diet (NC group), high fat and cholesterol diet (HFC group), and HFC diet supplemented with 5% fruiting powder of Hericium erinaceus (HFC+HE group). In the HFC+HE group, serum total cholesterol, low density lipoprotein, and triglyceride concentrations were significantly reduced compared with the NC group. Body weight gain of those in the HFC+HE group were lower than those in the HFC group; whereas HFC+HE had no effect on the levels of plasma albumin, creatinine, blood urea nitrogen, uric acid, glucose, and total protein. The enzyme activities related to the liver function, such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), and, alkaline phosphatase (ALP), were lower in the NC group than in the HFC group, but without significance. Feeding the mushroom increased the excretion of total lipid and cholesterol. A histopathological analysis showed that the those in the HFC group developed hepatic steatosis, whereas those in the HFC+HE group developed small fat droplet. In conclusion, these results suggest that 5% HE supplementation to HFC diet provided health benefits by acting on lowering atherogenic lipid profile in rats with high fat and cholesterol diet.

Objective: The purpose of this study was to investigate acute and subacute toxicity and sarcoma-180 anti-cancer effects of herbal acupuncture with Carthami- Tinctorii fructus (CF) in mice and rats. Method: Balb/c mice were injected intraperitoneally with Carthami - Tinctorii fructus (CF) for $LD_{50}$ and acute toxicity test. Sprague Dawley rats were injected intraperitoneally with Carthami- Tinctorii fructus (CF) for subacute toxicity test. The Carthami- Tinctorii fructus herbal-acupuncture was injected on Chung-wan (CV12) of mice with Sarcoma-180 cancer cell line. Results: 1. $LD_{50}$ was uncountable as none of the subjects expired during the test. 2. In acute toxicity test, toxic symptoms were not detected, but the body weight of mice was increased in treatment Ⅰ, treatment Ⅱ groups, compared to the normal group.(p<0.05) 3. In acute toxicity test of serum biochemical values of mice, glucose was increased in treatment Ⅰ and treatment Ⅱ groups, total cholesterol was increased in treatment I group, GOT was decreased in treatment Ⅱ group, and GPT was decreased in treatment Ⅰ group, compared to the normal group.(p<0.05) 4. The clinical signs and the body weight of mice treated with 0.1 cc, 0.2cc Carthami- Tinctorii fructus (CF) were not affected during the subacute toxicity test. 5. In subacute toxicity test, treatment groups didn't show significant changes in complete blood count test (CBC) of rats, compared to the nonnal group.(p<0.05) 6. In subacute toxicity test of serum biochemical values of rats, uric acid was decreased in treatment Ⅰ and treatment Ⅱ groups, compared to the nonnal group, triglyceride was decreased in treatment I group, compared to the normal group, GOT and GPT were decreased in treatment I and treatment Ⅱ groups, and alkaline phosphatase was decreased in treatment Ⅰ and treatment Ⅱ groups, compared to the normal group.(p<0.05) 7. Median survival time was increased in all the treatment groups for Sarcoma-180 cancer cell treated with Carthmni- Tinctorii fructus (CF).(p<0.05) 8. Natural killer cell activity was significantly increased in all the treatment groups compared to the normal group.(p<0.05) 9. Interleukin-2 productivity was decreased in treatment Ⅰ and treatment Ⅱ groups.(p<0.05) Conclusion: According to the results, we can conclude herbal-acupuncture of Carthami-Tinctoriifructus (CF) caused negligible toxkity, and had anti-tumor effects in mice.

The methanol extract of stem barks of Careya arborea Roxb. (MECA) (Family- Myrtaceae) was evaluated for antitumor activity and antioxidant status against Ehrlich's Ascites Carcinoma (EAC) bearing Swiss albino mice. After 24 h of tumor inoculation the MECA was administered at the doses of 50, 100 and 200 mg/kg body weight/mice/day for 14 days. After the last dose and 18 h fasting mice were sacrificed. The effect of MECA on the growth of transplantable murine tumor, life span of EAC bearing hosts, hematological profiles, serum and liver biochemical parameters were estimated. The MECA showed significant (P < 0.01) decrease in ascites volume, packed cell volume and viable cell count and prolonged the life span of EAC tumor bearing mice. Hematological profiles reverted to more or less normal levels in extract treated mice. The MECA also produced protective effect by decreasing the activity of serum enzymes, bilirubin and increase the protein and uric acid levels. MECA significantly (P < 0.05) decreased the levels of lipid peroxidation, while significantly (P < 0.05) increased the levels of glutathione content, vitamin C, vitamin E, superoxide dismutase and catalase CAT. The results indicate that MECA exhibited significant antitumor and antioxidant activity in EAC bearing mice.

We compared the long-term metabolic effects of equal amounts of carbohydrate from potato, rice and buckwheat on glycemic indices and blood lipids in healthy subjects. Nine healthy volunteers-2 men and 7 women were studied. All subjects ate diets based on the same-7-day rotating menu differing only in that the major source of carbohydrate (about 50% of daily total calories) came either from buckwheat, rice or potato. The study was conducted with a triple crossover design over three 7 day periods. On the morning of the 8th day, fasting blood was drawn from each subject to determine serum glucose, insulin, triglycerides, total and HDL-cholesterol. Subjects were then asked to eat breakfast with their respective carbohydrate within a 20 min period. Blood samples were drawn at 30, 60, 120 and 180 min after the start of breakfast to determine glucose and insulin levels. At 30 min the glucose response to the rice meal(7.15mmol/L) and potato meal(6.71mmol/L) were greater than the response to the buckwheat meal(5.855mmol/L) (P < 0.05). The mean area under the glucose response to the curve following the rice meal was greater than that following the buckwheat meal(P < 0.05). The insulin responses to the potato and rice meals at 30 and 60 min were greater than those to the buckwheat meal (P < 0.05). The mean area under the serum insulin response curve after the rice meal was greater than of buckwheat. Blood lipids, uric acid and glycosylated hemoglobin were not affected by the three meals. The study shows that the buckwheat meal has more beneficial effects on glycemic indices than either the rice meal or potato meal in healthy subjects.

An 8-year-old male red fox (Vulpes vulpes) in Species Restoration Technology Institute of Korea National Park Service (KNPS), revealed nodular growths in its ventro-cervical region. The fox was introduced from Young-Yang Gun in 2012 to KNPS for re-introduction of the red fox. It has been cared in captive facility and showed the mass in August 2013 that was sent to Wildlife Medical Center. For the diagnosis of underlying disease and cervical mass, radiographical and sonographical examinations, complete blood count, serum chemistry analysis, peripheral blood smear examination and surgical removal of the mass were performed. The mass was fixed in 10% neutral buffered formalin and processed routinely for haematoxylin and eosin (HE) stain. Based on hematological and serum chemical examination, the fox showed mild leukocytosis, thrombopenia, increase of creatine kinase MB (CKMB) and uric acid. However, it was considered as no clinical relevance since the fox showed no related clinical signs. Macroscopically, the mass was round shape, whitish and well-demarcated. Microscopically, it was diagnosed as a lipoma consisting of mature adipose tissue. Lipoma is a common benign tumor in most domestic animals, however it has never been reported in the red fox. The present case report provides comprehensive diagnosis of a subcutaneous lipoma in a red fox.

In 1965, Rosenberg reported that platinum compounds not only inhibit growth and cell division of E. coli but also has anti-tumor activity. Since then, through animal and clinical experiments by Welsch(1971), Speer(1972), Rossof(1972), Hill(1974), and Wittes(1975), it was proved that Cis-platinum has excellent supressive effects on malignant tumor, especially on head and neck cancer. Accordingly, Cis-platinum is now widely used, sometimes without any other durg, or sometimes with Bleomycin and Methotrexate etc. Inspite of the strong anticancer effect, the use of Cis-platinum is quite often discouraged because of the reports that Cis-platinum causes auditory impairment at high frequencies above the speech range due to inner ear damage and irreversible change in the renal tubules. Since Kohonen et al(1965), Standnicki et al(1974) reported that Cisplatinum has toxic effects at the basal turn of the cochlea using guinea pig, many studies on ototoxicity after infusion of Cis-platinum have been carried out using animals. But the studies on ototoxicity in human beings can hardly be found except in reports by Piel et al(1974) and Hong et al (1979). So the authors did a study which tried to clarify the ototoxic effect by comparing the hearing level after infusion of Cis-plastinum with the hearing level before infusion of Cis-plastinum in 30 patients who was treated with Cis-platinum and admitted to the dept. of otolaryngology of Yonsei University Hospital during 2 years and a half from July. 1979 to March. 1982 and the following results were obtained. 1) The results of auditory evaluation, using the pure tone average, hearing loss of 4kHz and 8kHz, Speech Reception Threshold, PB score, SISI showed that the difference of dosage does not change the hearing level after infusion of Cis-platinum and before infusion of Cis-platinum. 2) Cis-platinum had no effect on the hearing level of patients with conductive hearing loss, or with sensorineural hearing loss, as well as with normal hearing level. 3) The infusion of Cis-platinum did not cause any change in creatinine clearance, creatinine, uric acid, but only one case showed that Cis-platinum caused severe nephrotoxicity. 4) The infusion of Cis-plastinum did not cause any change in hemoglobin, leukocyte count, platelet count and there was no correlation with the amount of infusion. 5) To see the side effect of hydration practiced with the infusion of Cis-platinum, the electrolytes, particularly the K level in the serum was measured. But the results did not show any change. 6) Judging from the results of this study mentioned above, ototoxicity caused by infusion of Cis-platinum can be prevented by sufficient hydration. Also the results might say that the appropriate method of infusion of Cis-platinum might be effective in the patients with head and neck cancer who had sensorineural hearing loss for whom the infusion of Cis-platinum has been absolutely cotraindicated.

The preventive actions of methanol extracts from Ribes diacanthum Pall. (RDP) against high blood glucose levels in alloxan-induced diabetic mice were investigated. ICR mice (male, 8 wks) were divided into four experimental groups: a normal group (N), an alloxan-induced group (control), a RDP 1 mg/kg b.w./day + alloxan group (RDP-1) and a RDP 3 mg/kg b.w./day + alloxan group (RDP-2). Mice were fed RDP extracts for 14 days and then a diabetic condition induced by injecting alloxan (50 mg/kg b.w. i.v.). The total phenolic contents of RDP were 0.508 mg/g. Plasma glucose levels were significantly lower in RDP groups (RDP+alloxan) than the control (alloxan-induced diabetic group). In an oral glucose tolerance test, the glucose levels of RDP extract groups were significantly decreased compared to the control group. The levels of total cholesterol, triglycerides, AST, ALT, uric acid, and blood urea nitrogen in serum were lower in the RDP groups than the control group, whereas levels of HDL-cholesterol showed no difference between treatment groups. We conclude that RDP extracts positively influence blood glucose levels in diabetic mice.

This study was designed to evaluate the possible DNA damaging effects of T-2 toxin using an alkaline single cell gel electrophoresis (SCGE) comet assay and also to investigate toxic effects in chickens. A total of 20 chickens were used in these experiments. Graded concentrations of dietary T-2 toxin (0, 4, 8, and $16{\mu}g/g$ of diet) were given to groups of 5 broiler chickens. In comet assay, The DNA damage was analysed by the tail extent moment (TEM) and tail length (TL), which were used as markers of DNA strand breaks in SCGE. A significant dose-dependent increase in the extent of DNA migration as well as in the percentage of cells with tails was observed after treatment with T-2 toxin (P<0.05). Treatment with the low T-2 toxin ($4{\mu}/g$ of diet) induced a relatively low level of DNA damage in comparison with the high T-2 toxin ($16{\mu}/g$ of diet) group. The growth rate was significantly reduced by concentrations of 8, and $16{\mu}/g$ of diet (P < 0.05). The feed conversion ratio were significantly affected by any concentrations (P < 0.05). The relative weight of the spleen, and lung was decreased by the growth inhibitory concentrations. The bursa of Fabricius, thymus, and kid- ney were decreased in relative weight by concentrations of $16{\mu}/g$ of diet. The relative weight of the liver and heart were unaffected. The hemoglobin (Hb), hematocrit (HCT), and mean corpuscular hemoglobin (MCH) were decreased at concentration of $16{\mu}/g$ of diet. As compared with control chickens, there was no marked change in serum components except uric acid in T-2 treated chickens. All lymphoid tissues retained atrophic and lymphoid cell depletion throughout the three weeks trial.

The main character of the Korean diet has been found to be low in protein both quantity and quality and high in carbohydrate. The purpose of this survey was to study the amount of salt intake related to the dietary pattern in Korea. The nutrition survey was conducted in a mountainous farming area located in Auhchun-ri, Gaebuk-myon, Changsoo-gun, Chunbuk Province, February 14-19 in 1973 (7 days). The precise weighing method was used in evaluating the kinds of foods and nutrients intake for 24 households during a three day period. The physical examinations were performed by a doctor on 120 persons and a detailed biochemical test on both blood and urine was made on 42 persons over 40 years old. The results obtained are summarized as follows: (1) Average nutrients intake of an adult per day: calorie intake was 2,446 Cal and its components-protein(61.1g) was 10 percent, fat(12.9g) was 5 percent and carbohydrate(521g) contributed 85 percent of the total calories. Other nutrients-calcium (443mg), thiamine(1.09mg), riboflavin (0.90mg), niacin (14.4mg) and vitamin C (63.2mg) were lower than the recommended daily allowance but vitamin A(2,083 I.U.), iron(11mg) and phosphorous(998mg) were slightly higher than that. (2) To evaluate the nutritional deficiences, clinical examinations were conducted. Angular stomatitis was present in 16.7 percent of those examiners. No edema was found. The rate of osteoarthritis, hepatomegaly diseases appeared in 20 percent of the total subjects and the symptoms appeared highest among those Iron 50 to 59 years old. (3) The following chemical components of blood serum were analyzed and found to be within the normal range: glucose, blood urea nitrogen, uric acid, total protein, albumin, globulin, bilirubin, total cholesterol, inorganic phosphate, alkaline phosphatase, sodium, potassium, chloride, calcium and lecithine dehydrase. One case of each of the following were found: hyperglycemia, hypocholesterolemia, renal problem, hypoproteinaemia and diabetes mellitus, and two persons were classified as showing hypoglycemia and hyponaturemia. (4) The sodium content in urine was 199.6 mEq/L, potassium content was 24.6 mEq/L. The sugar, pH and specific gravity in the urine was shown to be normal.
