The concentrations of cadmium, metallothionein(MT), superoxide dismutase(SOD), and lactate dehydrogenase(LDH) were investigated in liver and kidney of rats which were fed the water containing 100 ppm cadmium chloride with basal diet and 5% Agaricus bisporus diet during 16 weeks. Cadmium concentrations in liver and kidney increased during 16 weeks, and there were significantly higher accumulation of cadmium in the kidney than in the liver. The concentrations of MTs in liver and kidney decreased linearly during 16 weeks, but there was no significant difference between control and experimental group. MT concentrations of liver were significantly higher than those of kidney. The superoxide dismutase activities and lactate dehydrogenase activities were not affected by the diet, but there was a significant difference by the duration of administration. These data indicate that the kidney is a major target organ of chronic cadmium poisoning, and suggest that Cd-induced hepatic injury, via release of Cd-MT, may play an important role in the nephrotoxicity. In conclusion, induction of MT occurs in both the liver and the kidney after administration of $CdCl_2$. However, the kidney is less responsive than the liver to the induction of MT by cadmium, which may contribute to making the kidney the target organ of toxicity during chronic Cd exposure.

The purpose of this paper was to investigate the bioavailability of oxytetracycline in pathological rats and rabbits pretreated with carbon tetrachloride and mercuric chloride. The results are as follows: The blood level of oxytetracycline administered orally was mostly decreased significantly in rabbits damaged kidney and liver, and in rabbits severely damaged kidney, the blood level of oxytetracycline was not significant at 4 to 6 hours. Urinary clearance of oxytetracycline in rabbits severely damaged kidney was inhibited at 5 to 6 hours but in rabbits damaged liver. Hepatic clearance of oxytetracycline was accelerated in rabbits damaged kidney but in rabbits damaged liver. AUC of oxytetracycline orally administered in rabbits damaged liver and kidney was largely decreased. The absorption of oxytetracycline was decreased in rats damaged liver and kidney as compared with that of normal rats. Especially, absorption of oxytetracycline in rats damaged liver was more decreased than that of rats damaged kidney. The absorption of oxytetracycline was inhibited by combinated administration of carbon tetrachloride and mercuric chloride.

In this study, the effect of squid liver powder intake on accumulation of cadmium in mice was investigated. Subjects were divided into 4 groups including the control group (CON), squid liver powder group with lipids not removed (SLP100), and squid liver powder groups with lipids removed (LFSLP50 and LFSLP100). Feed intake and food efficiency ratio of squid liver powder groups was significantly higher than the CON. As a result of investigating cadmium content in hair, serum, liver, and kidney during intake of squid liver powder, all groups showed increase in cadmium accumulation through consistent, long-term intake. Especially, cadmium content in liver and kidney of LFSLP100 was significantly higher than the content of SLP100 and CON. As a result of pathological observation on liver and kidney tissues according to squid liver powder diet, LFSLP100 showed most serious pathological symptoms. In case of kidney tissues, degeneration was significantly more severe in LFSLP100 compared to other groups. Such results suggest that cadmium concentration in human body can be increased by ingestion of whole squid including internal organs and that tissues can be damaged by increased cadmium concentration. More specific and systematic studies are deemed necessary.

Effect of freeze drying leek against cadmium poisoning on glutathione peroxidase, on glutathione reductase and on glutathione-s-transferase in liver, kidney and testes of the male rats during the administered period. In this experiment, male rats of Sprague-Dawley strain were used. The rats which were fed for 15 weeks were divided into 4 groups basal diet 3% leek added diet basal diet and cadmium in water and 3% leek added diet and cadmium in water. Cadmium was administered ad libitum 100ppm CdCl$_{2}$ in distilled water. The followings are the result of this experiment. 1. Leek enhanced the glutathione peroxidase activities which were reduced by cadmium treatment in liver, kidney and testes but not significance. 2. Leek reduced glutathione reductase activities which were incresed by cadmium in liver, kidney and testes. 3. Leek incresed the activities of glutathfone-s-transferase in liver but not in kidney and but not in testes. 4. Leek incresed glutathione concentration which was decresed by cadmium treatment in liver and kidney but not testes. This experiment showed that leek-addition group had protective effect against cadmium poisoning and alleviated GR and glutathione-s-transferase activities in tissues. Leek incresed activities of glutathione peroxidase in liver, kidney and testes but not significance. Therefore, this experiment concluded that leek defensive power against long term cadmium poisoning.

The effects of total dietary restriction(100% restriction of energy intake) on thiobarbituric acid reactive substance(TBARS) contents and intracellular antioxidant enzymes activities in the liver and kidney of young male Sprague Dawley rats were studied. The TBARS contents were reduced in both liver and kidney, up to 77% and 79% of the control rats, fed ad libitum, respectively at 7 days after dietary restriction . Superoxide dismutase(SOD) activities in the liver and kidney of rats were increased significantly by total dietary restriction. However, the activity of catalase in kidney was decreased 27% at 6 days after dietary restriction, but this enzyme activity did not change in liver. The changes of glutathione peroxidae(GSHPx) and catalase activities in the liver and kidney of rats with dietary restriction were not significant. These result suggested that dietary restriction reduce the free radical induced by tissue damage, as determined by TBARS content, in both the liver and kidney but the changes of activities of antioxidant enzymes may not be a contributory factor in reducing oxidative damage to tissue.

Purpose: This study evaluated the characteristics and the prognosis of multiple intraabdominal solid organ injuries, including those to the liver, spleen, and kidney, after blunt trauma. Methods: From January 2001 to March 2009, 39 patients with multiple intraabdominal solid organ injuries, which had been confirmed by contrast-enhanced computed tomography after blunt trauma, were included in this retrospective study. The injury severity score (ISS), abbreviated injury scale (AIS), revised trauma score (RTS), American Association for the Surgery of Trauma (AAST) injury grade of solid organs, initial hemodynamic status, blood gas analysis, blood transfusion, and the mortality were the main outcome measurements. Results: Injured groups were classified into liver/kidney (n=17), liver/spleen (n=4), spleen/kidney (n=13), and liver/kidney/spleen (n=5) groups. Patients were older in the liver/kidney group than in the liver/kidney/spleen group (43 vs 18 years, p=0.023). The initial systolic blood pressures tended to be lower in the liver/kidney group than in the other groups (84 vs 105, 112, and 114 mmHg, p=0.087). The amounts of 24-hour packed RBC transfusion were 32 units in the liver/kidney group and 4 units in the liver/kidney/spleen group, but the difference was not statistically significant. Differences were found in neither the RTS, ISS, and AIS for head, chest, abdominal, and pelvic injuries nor the AAST injury grade for solid organ, but injuries to the chest were more severe in the liver/spleen group than in the spleen/kidney group (AIS 4.0 vs 2.8, p=0.028). Conservative treatment was the most frequent applied treatment in all groups. There were 6 mortalities : 3 due to hypovolemia, 2 to sepsis, and 1 to brain injury. Mortalities occurred only in the liver/kidney group. Conclusion: Patients who had intraabdominal solid organ injuries of the liver and the kidney simultaneously, tended to be transfused more at an early time after trauma, to have lower initial systolic blood pressures, and to have a higher mortality.

Collagen is a family of proteins which consists of several genetically distinct molecular species and is intimately involved in tissue organization, function, differentiation and development. The purpose of this study was to investigate the concentration of different hydroxyproline (Hyp) fractions viz., total, free, peptide-bound, protein-bound, soluble- and insoluble-collagen hydroxyproline (Hyp) in various bovine tissues. Results showed that liver had the highest concentration of free Hyp followed by kidney, brain, spleen, lungs, muscle and heart. Liver also had the highest concentration of peptide-bound collagen Hyp followed by kidney, heart, spleen, lungs, brain and muscle. The concentration of protein-bound collagen Hyp was highest in the liver, followed by kidney, spleen, lungs, muscle, brain and heart. Total Hyp was highest in the liver, followed by kidney, spleen, brain, heart, muscle and lungs. Liver also had significantly high concentration of collagen as compared to other tissues examined (P<0.001). Spleen had the significantly higher concentration of soluble-collagen Hyp when compared to other tissues (P<0.001). This was followed by heart, muscle, lungs, brain, kidney and liver. Heart had the highest concentration of insoluble-collagen Hyp followed by lungs, kidney, liver, muscle, spleen and brain. The variation among the insoluble-collagen Hyp concentration of heart and muscle, spleen and brain was significant (P<0.001). We speculate that these differences could be due to the variation in turn over of rate of collagen metabolism in this species.
