  • This study was investigated the effects of the lower power He-Ne IR laser treatment on the changes of blood biochemical components in the rat liver damaged by the carbon tetrachloride (CCl₄). The twenty one Sprague-Dawley adult male rats weights (260±18.6 g) were designed to the three groups: one control group and two experimental groups, the experimental groups were divided into the CCl₄-treated groups and the laser therapy group (CCl₄+ Laser). The experimental groups were injected twice with CCl₄(1.0 ml/kg body weight) intraperitoneal for two days. Each group was sacrificed after two weeks irradiated with the lower power He-Ne IR laser for ten minutes per every day. The activity of alanine aminotransferase (ALT), lactic dehydrogenase (LDH), alkaline phosphatase (ALP) and the concentration of serum glucose treated with He-Ne IR laser groups was significantly decreased to the conrtol (treated with carbon CCl₄) group. The activity of aspartate aminotransferase (AST) was decreased in the laser group but not significantly, the concentration of the serum cholesterol in the laser group was significantly increased comparing with the control and case control groups. In conclusion, the effect of the lower power He-Ne IR laser treatment is believed to be a possible protective effects for CCl₄ induced acute hepatotoxicity in rats.

  • The purpose of this study is to inspect trends of the paper of Korean medical treatment on Carbon Tetrachloride-induced Hepatotoxicity and try to establish the future direction for development of Korean herbal medicine. We reviewed 79 papers which had been published from 1981 to 2010 in journals published in Korea. According to these studies, Carbon Tetrachloride-induced hepato-celluar degeneration and necrosis induced to increase in serum aspartate amintransferase (AST), alanine aminotransferase (ALT), Alkaline phosphatase (ALP), ${\gamma}$-Glutamyl transferase (${\gamma}$-GTP), lactate dehydrogenase (LDH), bilirubin, blood urea nitrogen (BUN) and albumin levels. In biochemical analyses, antioxidant enzymes such as superoxide dismutase (SOD), Glutathione S-transferase (GST) and catalase in hepatic tissue were remarkably incresed by Carbon Tetrachloride treatment. We found that some of the herbal extracts have a protective effect against Carbon Tetrachloride-induced Hepatotoxicity. More studies of oriental medicinal herbs are required for developing a treatment of hepatotoxicity.

  • The objective of this study was to characterize the adverse effects of Ahnjon-Yichun-Tang during early pregnancy. Following successful mating, female Sprague-Dawley rats were given Ahnjon-Yichun-Tang(AYT) extract by oral administration daily with dose of 150mg (n=10), 300mg(n=10), 450mg(n=10) for 20 days of pregnancy. The rats in Control group(n=10) were orally administrated with Saline. All pregnant rats of Ahnjon-Yichun-Tang-treated and Control groups were sacrificed on day 20 of pregnancy. The pregnancy outcome was determined and the internal and reproductive organs of pregnant rat were observed. The fetuses were examined for the presence of various developmental toxic endpoints and stained with alcian blue and alizarin red S, and observed skeletal malformations. The results obtained in this study represent that there is no significant changes between Control and Ahnjon-Yichun-Tang-treated groups in body weight, organ weight, blood chemistry values, hematological values and pregnancy indexes of pregnant rat. The skeletal malformation of fetus was not observed as well. These results suggest that oral administration of Ahnjon-Yichun-Tang does not produce either maternal or developmental toxicity.

  • The hypoglycemic effect of an exo-biopolymer (EXO) and endo-biopolymer (ENDO) produced from submerged mycelial culture of Ganoderma lucidum was investigated in streptozotocin (STZ)-induced diabetic rats. Both the EXO and ENDO showed hypoglycemic potential, however, the former proved to be more potent than the latter. The administration of the EXO at the dose of 100 mg/kg body weight (BW) significantly reduced the plasma glucose level (23.5%) and increased the plasma insulin level (2.2 fold) in the diabetic animals. The EXO also lowered the plasma total cholesterol, triglyceride, low-density lipoprotein (LDL) cholesterol, and athrogenic index by 14.7, 31.4, 24.1, and 45.4%, respectively, and reduced the liver total cholesterol and triglyceride levels by 6.7 and 25.8%, respectively. It increased the plasma high-density lipoprotein (HDL) cholesterol (37.7%), compared to the control group. Furthermore, the alanine transaminase (ALT) and aspartate transaminase (AST) showed lower activities in the EXO administered groups than the other experimental groups. Taken together, these results suggest that the exo-biopolymer may alleviate the blood glucose level by increased insulin secretion.

  • This study investigated the physiological effects of a diet containing calcium oxide (CaO) on the olive flounder, Paralichthys olivaceus. The results indicate that the amount of calcium in the blood was higher in the calcium group compared with the controls. The aspartate amino transferase (AST) and alanine amino transferase (ALT) levels were lower in the calcium group, while lysozyme activity was higher in the calcium group. Histologically, fish in the calcium group had more hepatocytes in the liver and more intact scales. In addition, an attack experiment using Vibrio anguillarum (KCTC-2711) and Edwardsiella tarda (KCTC-3657) showed that the survival was higher in the calcium group compared with the controls. These results suggest that feeding fish CaO when they require it, such as during periods of gonadal maturation and rapid growth, will increase their immunity and resistance to pathogens.

  • The toxicity and histopathologic changes of diazinon (O, O-diethy-O-(2-isopropyl-6-methyl-4-pyrimidinyl)phosphorothioate) was investigated in rat. Rat was treated with diazinon (100 mg/kg/day) by oral administration for 12 days. The experimental results were summarized as follows. Biochemical parameters such as ALT, AST, LDH and glucose in serum were significantly increased and hematological parameters such as Hb, Hct and PLT in blood were slightly increased in treated groups. Also the activities of serum cholinesterase were very significantly decreased in treated groups. In the histopathological changes, the normal lobular architectural pattern of the liver was well preserved in all treated groups. However, vacuolation or fatty change were represent in hepatocytes. Sections of liver from rats treated with diazinon for 3 and 6 days contained slight lipid infiltration in the form of small droplets randomly distributed that were graded minimal (+) or moderate (++) compared with the respective control condition. After 9 days, there were numerous small and large vacuoles in the terminal hepatic venule and perilobular areas of many serial sections of these rats indicative of fatty infiltration which were graded moderate (++) and severe (+++). After 12 days, fatty infiltration progressed periportal tract areas and graded severe (+++) and very severe (++++) in experimental groups. Note absence of cellular necrosis or inflammation.

  • The hypoglycemic effects of four edible plants (Angelicae tenuissimae (A. ten.), Pleurospermum kamtschaticum (P. kam.), Adenophora remotiflora (A. rem.) and Zanthoxylum schinifolium (Z. sch.)) in streptozotocin (STZ) -induced diabetic rats were investigated. Sprague-Dawley male rats weighing 190-230 g were induced diabetes mellitus by the STZ injection (45 mg/kg) into the tail vein and were divided into six groups ; normal, STZ-control and four edible plant groups (A. ten., P kam., A. rem. and Z. sch. groups). Normal and STZ-control groups were fed a AIN-93 diet and four groups of STZ-induced diabetic rats were fed one of each experimental diets containing 10% of the edible plant powder for 4 weeks. Diabetic rats showed the lower weight gain compared to the normal rats. In experimental groups except P. kam., AST activities were close to normal. A. ten. group were lowered ALT activities slightly. The plasma glucose levels of the diabetic experimental groups were significantly decreased at 4th week. The plasma insulin levels in diabetic experimental groups were not significantly different compared to the STZ-control group. The liver glycogen levels in STZ injected rats were significantly lower in compared to the normal rats. However no significant differences were found in response experimental plants intake in diabetic rats. The muscle glycogen were not significantly different among all the groups.
