Antimetabolited인 6-aminonicotinamide(6-AN)가 토끼의 혈청내 효소 및 대사 물질에 미치는 영향에 관하여 연구하였다. 복강투여시 (l5mg/kg의 체중) 포도당과 콜레스테놀농도는 현저이 증가하였으나 알부민고 총단백질량은 크게 변하지 않았다. Creatine phophokinase,glutamic oxaloacetate transaminase,glutamic pyruvate transaminase 및 alctate dehydrogensenase활성은 매우 증가하였으며 alkaline phosphatase와 Ca, P, Na, K, Cl 및 Co등의 수준은 영향을 받지 않았다.

cis-Dichlorodiammineplatinum(cisplatin) is one of the most effective antitumor agents currently available for cancer therapy. However, its clinical use has been limited by its severe side effects, especially nephrotoxicity. So, to evaluate the effects of 2(3)-tert-butyl-4-hydroxyanisole(BHA) on cisplatin nephrotoxicity in rats, both compounds were given intraperitoneally. Remarkable protective effects of BHA against nephrotoxicity of cisplatin were observed when BHA was administered to rats 1hr after cisplatin injection. On the other hand pretreatment with BHA 1hr prior to cisplatin did not reduce weight loss, blood urea nitrogen and creatinine levels. Hepatotoxicity induced by combination treatment of cisplatin and BHA was evaluated by measuring serum glutamic pyruvate transaminase and serum glutamic oxalate transaminase. Combination treatment did not affect the levels of SGPT and sGOT except 1hr pretreatment. The present results indicate that BHA may provide protection against cisplatin nephrotoxicity, when it is given 1hr after cisplatin.

Cisplatin is one of the most effective antitumor agents currently available for cancer therapy. However, its clinical use has been limited by its severe side effects, especially nephrotoxicity. Therefore, brazilin, which has a radical scavenging effect, was given intraperitoneally to evaluate the effect on cisplatin nephrotoxicity in rats. Remarkable protective effects against nephrotoxicity of cisplatin were observed when brazilin was administered to rats simultaneously with cisplatin. Hepatotoxicity induced by combination treatment of cisplatin and brazilin was evaluated by measuring serum glutamic pyruvate transaminase and serum glutamic oxalate transaminase. Combination treatment did not affect the levels of sGPT and SGOT, and any combination treatment did not induce metallothionein in kidney. Brazilin which has radical scavenging effect directly reduced nephrotoxicity of wisplatin in vivo. Thus, it seems that nephrotoxicity of cisplatin was caused by free radicals. The present results Indicate that brazilin, when it is given with cisplatin, may provide protection against cisplatin nephrotoxicity in rats.

Chlorpyrifos (CPF) is one of the most heavily used organophosphate pesticides and is useful as an insecticide drug. However, CPF also causes toxic effects in nontarget organisms, including humans and animals. Jageum-Jung (JGJ) is a traditional oriental medicine, composed of five specific herbs with antioxidant and hepatoprotective properties, used for detoxification. In the present study, highly concentrated CPF was orally administrated to male Institute of Cancer Research mice to produce acute toxicity, and the protective effects of JGJ administration were investigated through statistical analysis of changes in body and organ weights and serum biochemical parameters. JGJ caused body and organ weights to recover and reduced the levels of serum biochemical parameters indicative of liver damage, such as glutamic oxalate transaminase, glutamic pyruvate transaminase, alkaline phosphatase, lactic dehydrogenase, urea, glucose, total cholesterol, and triglyceride, that had been increased by CPF treatment. Our results demonstrated that JGJ ameliorates the effects of acute chlorpyrifos-induced toxicity. Therefore, JGJ has the potential to be used as a traditional medicine to alleviate insecticide toxicity.

The objective of the current study was to determine acute plasma stress responses in two size groups of juvenile Epinephelus akaara (average body weight: $8.4{\pm}2.1$ and $3.3{\pm}0.6g$; 150 and 120 days after hatch, respectively) exposed to abrupt salinity drops (from 34 practical salinity unit, PSU seawater to 18, 10 PSU (experiment 1) or 26, 18, 10 PSU (experiment 2), respectively). Plasma glucose, glutamic oxalate transaminase, glutamic pyruvate transaminase, red blood cell counts, and gill histology were determined during 72 h exposure. Significantly increased plasma glucose, glutamic oxalate transaminase levels, and red blood cell counts were observed in fish exposed to 18 or 10 PSU. Histological changes, such as hyperplasia and lifting of epithelium in the gill secondary lamellae, were also observed in fish exposed to 18 or 10 PSU at 72 h post-drop. E. akaara exposed to sudden salinity drops to 18 or 10 PSU still seems to undergo the primary adjustment phase before fish reaches a new homeostasis, whereas fish exposed to 26 PSU seems to mount osmotic changes. Therefore, the no observed adverse effect levels for 72 h acute salinity challenge was 26 PSU in our study, and salinity drop to 18 PSU and below can possibly cause acute adverse effect, in which fish could be vulnerable to additional stresses such as a temperature changes or handling stress.

To investigate the effects of yellow soybean powder on serum lipid level and enzyme activities, male Sprague-Dawley(SD) rats were given hyperlipidemic diets for 6 weeks. Rats(n=8) were divided into three groups consisting the normal group(N), hyperlipidemic diets group(C) and hyperlipidemic diets and yellow soybean powder group(YSP). YSP group lowered triglyceride, total lipid, phospholpid, ester-cholesterol and free-cholesterl than control group. YSP group lowered total-cholesterol, VLDL-cholesterol and LDL-cholesterol but increased HDL-cholesterol of the serum compared to the control group. Athergenic Index(AI) and LHR(LDL-cholesterol/HDL-cholesterol ratio) of YSP group was decreased by control group (p<0.05). On the other hand, glutamic oxaloacetate transaminase(GOT), glutamic pyruvate transaminase (GTP), lactate dehydrogenase(LDHase) and alkaline phosphatase(ALP) enzymes activities were decreased by hyperlipidemic diets group (C). These results suggest that yellow soybean powder fed a lipid lowering effect in serum of rats.

Juvenile Paralichthys olivaceus (mean length $17.3{\pm}2.2cm$, mean weight $46.5{\pm}6.3g$) were exposed for 10 days to tributyltin (TBT) at various concentrations (0, 1, 2, 4 and $8{\mu}g/L$). Hematological parameters, such as red blood cell (RBC) count, hematocrit (Ht), and hemoglobin (Hb) concentration, were considerably decreased by high TBT concentrations. In plasma constituents, inorganic components such calcium and magnesium were also significantly altered. Plasma calcium was notably decreased, whereas plasma magnesium was increased. The enzyme components, glutamic oxalate transaminase (GOT) and glutamic pyruvate transaminase (GPT), were significantly decreased by TBT exposure. The present findings suggest that TBT exposure can cause significant alterations in hematological parameters and plasma constituents of flatfish Paralichthys olivaceus.

This study was to examine the lipid metabolism of fermented Rhynchosia nulubilis (FRN) in obese rats. The abnormal content of blood lipids often results in metabolic diseases, such as obesity and hyperlipidemia. Seven weeks female Sprague-Dawley rats were divided into four groups and fed high fat diets for 44 days. Also FRN was administered orally for 44 days at 7.5 ml/kg of body weight of rats. The effects of the lipid metabolism were evaluated by total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), glutamic pyruvate transaminase (GPT) and glutamic oxalacetic transaminase (GOT) levels in sera. The levels of TC, TG, LDL and GPT in FRN-treated groups were lower than those in obese groups. While HDL levels were significantly increased. These results demonstrated that FRN had improving effects of lipid metabolism in the obese rats, suggesting that FRN would be used as an ingredient of the useful functional products.
