This study was carried out to investigate the effects of enzyme activities on male Sprague-Dawley rats intoxicated by CCI4 on IS(Godulbaegi) diets for 4 weeks. We divides into 5 diet groups which were normal diet(N), normal diet intoxicated by CCI4(NC) and 3 IS diets ; leaves diet(ILC), roots diet(IRC) and mixed diet of leaves and roots which were also injected by CCI4 3 times for 4 weeks. The activity of glutamic pyruvic transaminase(GPT) in serum in NC was higher than in N as we expected. The GPT activites and the values of malondial-dehyde(MDA) of IS groups were all lower than in NC, IC as lowest. The activity of superoxide dismutase(SOD) in NC was higher than in N and IS groups had values less than the values of N. Catalase showed similarity in results as above. The values of glutathione S-transferase(GST) and cytochrome P-450 in NC were lower than in N. IS groups had higher values than in NC. Godulbaegi might be important not only as one of the traditional Korean foods but also as therapeutic agent for hepatotoxicity and for shortening the recovery time in liver disease.

Effects of betaine, a major component of Lycii Fructus, on carbon tetrachloride intoxicated rats were evaluated. Histological studies showed that betaine had improved the typical necrosis around centrilobular area in liver tissue due to the carbon tetrachloride intoxication. Betaine, whether it was administrated simultaneously or prior to carbon tetrachloride, prevented or retarded the elevation of liver-weight/body-weight ratio due to the carbon tetrachloride intoxication. Betaine also significantly elevated the reduced activities of some enzymes, cytochrome P-450, 7-ethoxycoumarin-0-deethylase and glutathione-S-transferase, involved in xenobiotic metabolism due to carbon tetrachloride intoxication. These results demonstrate a possible hepato-protective role of betaine against fatty liver that could be easily induced by carbon tetrachloride in rat.

The toxicity of the mixture of diazinon, toxaphene(TOX) and/or endrin was studied in ICR male mice(18-22 g) by oral intubation, in corn oil, daily for up to 14 days. On day 15, the exposure was discontinued and animals were monitored for an additional period of 7 days for the possible reversibility of the toxicity. The body weight gain decreased with the mixtures, as well as with the individual pesticides, during the 14-day period. TOX and TOX containing mixtures significantly increased the liver/body weight ratio. The serum glutamic pyruvic transaminase level increased at 23~374% in diazinon, TOX, and endrin or their mixture group. The cholinesterase(ChE) activity in the serum and brain was inhibited in the animals of the group of diazinon(5, 10 mg/kg) and diazinon(5 mg/kg) containing mixtures. TOX(40, 80 mg/kg) caused initial inhibitory effects on the serum ChE Day 1. but there is little effects on the brain ChE levels. endrin(5,10 mg/kg) results in significantly elevated levels of the serum ChE, with substantial decreases in the brain ChE activity. TOX and TOX containing mixtures decreased the pentobarbital(60 mg /kg, ip., in saline) induced sleep. The effects produced by this pesticides singly, as well as by their mixtures, appeared to be reversible in nature. The toxic effects exhibited by the mixtures of diazinon(5 mf/kg), TOX(40 mg/kg), and /or endrin(5 mg/kg) were found to be the resultant of the effect showed by their components individually.

This study was performed to investigate the possible effects of some plants protecting intact rat liver damaged by $CCl_4$. The extract of mugwort (Artemsiae capillaris), soybean sprout and pine leaf (Pinus strobus) inhibited markedly the in vitro activities of rat liver fatty acid synthase, whereas those of shiitake (Lentinus ododes), Houttuynia cortata, Acanthopanacis cortex and buckwheat leaves had less effects. Treatment with the water extract of pine leaf and soybean sprout caused a marked decrease in the $CCl_4$-induced toxicity in rat liver, judged from their effects on the levels of glutamic oxaloacetic transaminase (GOT) and glutamate pyruvic transaminase(GPT) in the serum. The extract of mugwort and soybean sprout reduced markedly the content of liver microsomal peroxides induced by $CCl_4$ treatment and serum TBA values, respectively. The extract of soybean sprout decreased efficiently the content of liver triglyceride elevated by $CCl_4$ treatment. Nevertheless, the extracts did not exert the supression of hepaticmegaly induced by $CCl_4$. The results suggest that soybean sprout and pine leaf may be potential sources improved the biochemical parameters like as peroxidation value or serum GOT and GPT, although these extracts had minimal effects in the increase of liver size induced by carbon tetrachloride.

To assess the industrial possibility of mixed-extracts containing Hovenia dulcis Thunberg and 12 different botanical ingredients, a protective effect was confirmed in the chronic ethanol-induced the liver, brain, and blood injury in mouse. Blood glucose levels of the normal control group(NG) and ethanol administration group(EG) were respectively 119.43mg/dL and 305.25mg/dL, and the mixed-extracts administration group(100, 200mg/kg body weight + 25% ethanol 5g/kg body weight respectively; ME100 & ME200) were decreased to 272.76mg/dL and 234.60mg/dL. Blood ethanol contents were decreased in ME100 and ME200(3.85mg/dL, 3.08mg/dL) compared to EG(4.08mg/dL), and blood acetaldehyde contents were also decreased in ME(15.76mg/dL, 15.16mg/dL) compared to EG(18.72mg/dL). The contents of hepatotoxic indicators such as glutamine pyruvic transaminase(GPT) and glutamic oxaloacetic transaminase (GOT), nephrotoxic indicators such as blood urea nitrogen(BUN), and creatine(CRE), and total cholestero(TCHO), and triglyceride(TG) in mouse blood serum were significantly decreased in the ME compared to EG. The acetylcholinesterase(AChE) activity of ME(109.00% and 108.47%, respectively) in mouse brain tissues was decreased in ME compared to EG(116.10%). Finally, ME was remarkable in vivo antioxidant activities in the mouse liver and brain tissues by superoxide dismutase(SOD), oxidized glutathione(GSH)/total GSH ratio and the malondialdehyde (MDA) assay. Therefore, the mixed-extracts was considered to be effective a high value food with protective effect against chronic ethanol traetment-induced cytotoxicity in liver and brain tissues.

Objectives This study aimed to investigate the effect of Bangkibokryeong-tang (BBT, Fangjifuling-tang) on blood glucose and body fat in high-fat diet-induced obese mice. Methods The experimental animals were divided into five groups- normal diet-fed control (ND), high-fat diet-fed control (HFD), HFD+BBT 75, HFD+BBT 150, and HFD+olistat as a positive drug control group. Markers of obesity, such as body weight, organ weight, diet efficiency, and serum levels of total cholesterol, triglycerides, lipid content, leptin, adiponectin, glutamic oxaloacetic transaminase (GOT)/glutamic pyruvic transferase (GPT)/lactate dehydrogenase (LDH), blood glucose, and insulin, were measured. Furthermore, results of the oral glucose tolerance test and ${\alpha}-glucosidase$ inhibition activity were examined in obese mice. Results Mice treated with BBT demonstrate lower body and organ weight, and reduced weight gain and food efficiency than that in the HFD-only control group. In addition, BBT decreased lipid accumulation in the liver and the levels of enzymes such as GOT, GPT, and LDH in the serum. Furthermore, the levels of triglycerides, total cholesterol, low density lipoprotein (LDL), and leptin were decreased in the serum but the levels of high density lipoprotein (HDL) and adiponectin were increased in the BBT-treated group compared with the control group. The BBT-treated group also demonstrated decreased blood glucose and insulin concentrations induced by feeding on a high-fat diet and improved glucose tolerance. Conclusions Based on the results above, BBT may reduce body fat and hyperglycemia in HFD-induced obesity. This suggests that BBT may be clinically useful in the treatment of obesity.

These experiments were undertaken in order to find out the useful clinicopathological diagnostic methods of cadmium poisoning in dogs. Twenty-one dogs were divided into a control group and 6 experimental groups. The experimental groups were adminstered orally 5, 10, 15, 30, 60 and 120mg of cadmium per kg of body weight for 56 days. All dogs were examined for clinical signs, and weekly changes in hematological and blood chemical values. All dogs were necropsied on 57th days of experiment. Tissue samples including hair, skin, muscle, lung, liver, kidney, spleen, pancreas, testis, ovary, uterus, and bone were collected and analyzed for cadmium, zinc, iron and copper contents using atomic absorption spectrophotometer. From these experiments following results were obtained : 1. All experimental dogs showed vomitting, salivation, anorexia, decreased water-intake, dehydration, and marked weight loss. The dogs received 30mg/kg or more of cadmium died during the period from 2nd to 7th week after administration. 2. Hematologically, all experimental dogs showed decrease in erythrocyte count, hemoglobin concentration, and packed cell volume. The anemia was identified as normocytic and regenerative morphologically. 3. No significant differences in serum glutamic oxaloacetic transminase, glutamic pyruvic transaminase, blood urea nitrogen, and cholosterol value were obseved between the control and experimental dogs. 4. The cadmium contents in various tissues of experimental dogs were estimated as $37.8{\sim}201.8{\mu}g/g$ in bone, $14.1{\sim}49.5{\mu}g/g$ in liver, $13.2{\sim}53.1{\mu}g/g$ in kidney, $0.4{\sim}35.2{\mu}g/g$ in pancreas, $0.8{\sim}35.4{\mu}g/g$ in spleen, $0.9{\sim}30.1{\mu}g/g$ in hair, $0{\sim}7.1{\mu}g/g$ in lung, $0{\sim}5.1{\mu}g/g$ in skin, and $0{\sim}3.6{\mu}g/g$ in muscle, respectively. However, the serum, testis, ovary and uterus showed no cadmium accumulation. Two contol dogs showed cadmium accumulation only in bone. 5. Significant differances in zinc, iron, and copper contents in tissue samples were observed between the control and experimental groups.

The study was carried out to examine effect of cadmium spraying on mulberry leaves on the growth and metabolism of mulberry tree.The results obtained were as follow:1. Brown spot were appeared on the leaves as the symptoms of damage and the damage was remarkable with higher concentration of cadmium.2. Higher concentration of Cd inhibited the length and diameter of mulberry branches with a significant difference (P<0.05) for the length. The growth of branch length in both 5 and 7 ppm treatment of Cd was inhibited by 31% compared with the control. 3. Cadimum concentration of mulberry barks was noticeably lower than that of leaves. 4. Cadimum concentration over 3ppm inhibited significantly chlorophyll content, activitsies of respiration, glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transase (GPT) and adenocine triphosphate (APT). 5. The lowest concentration of cadmium was identified to be 3ppm to incur the inhibitory effect on the growth and metabolism of mulberry and cadmium content of mulberry leaves at the concentration was 13.86ppm.

The energy metabolism with the normal laying hen and progesterone injected non-laying hen are compared. 1. The FHP of 109.7Kcal for laying hen was 25.5 percent higher than the 87.4 Kcal found for non-laying hen. 2. The MEm's of laying hen and non-laying hen were 149, and 135Kcal/Kg$\^$0.75/day and NAME's of the diets were 77 and 83 percent, respectively. For the laying hen shown negative retention in body energy during the experiment, the 77 percent NAME was the value of supporting egg production. For the non-laying hen shown the positive retention in body energy and zero egg production, the 83 percent NAME was of growth. 3. A change in body weight of 1g was comparable to 3.54 Kcal for laying hen, and 5.0 Kcal for non-laying hen, when calculated on regression equations between body weight change and body energy retention(BE). The figures indicate that the tissue energy is used with an efficiency of 70 percent for egg production. 4. Plasma level of triiodothyronine(T3) for the laying hen is appeared to be higher than that of non-laying hen, although the levels of thyroxine (T4) are equal both in laying and non-laying hen. 5. Activities of four hepatic enzymes(ATP citrate lyase, fructose diphosphate aldolase, isocitrate dehydrogenase and glutamte pyruvic transaminase) were significantly greater in the laying hen than in the non-laying hen.

The effects of dietary fiber isolated from Synurus deltoides on constipation induced by loperamide (4 mg/kg/day) were investigated. Food intake and body weight both decreased in the 5% S. deltoides dietary fiber and loperamide-treated group (SD5) and 10% S. deltoides dietary fiber and loperamide-treated group (SD10), whereas fecal water contents increased by 2.4 and 3.4-fold in the SD5 and SD10 groups, respectively. The concentrations of total-cholesterol, HDL-cholesterol and triglyceride in the sera of the SD5 and SD10 groups were lower than those in the control (C) group. However, the biochemical parameters, GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyruvic transaminase), and glucose levels, were not affected by the level of S. deltoides. In addition, the concentrations of total-cholesterol and triglyceride in the livers of the SD5 and SD10 groups were also significantly lower than those in the control group. These results suggest that dietary fiber isolated from S. deltoides might ameliorate constipation symptoms, and lower lipid concentrations in the blood and liver.
