The effects of Geumguesingitang and Dohongsamultang on rats with nephrosis induced by a single tail-intravenous injection of puromycin aminonucleoside(PAN), 2.5mg/l00g of body weight were evaluated in the present study. The effects of Geumguesingitang and Dohongsamultang on PAN nephrosis were evaluated by measuring (1)the concentrations of albumin, total protein, total lipid, cholesterol, triglyceride, creatinine, blood urea nitrogen(BUN) and uric acid in the serum, (2)the concentrations of protein, creatinine, glucose, occult blood and volume of the 24 hours urine and (3)the volume of intake water. The results are summerized as follows; 1. In the Control group as compared to the Normal. the amount of protein of 24 hours urine was significantly increased, the concentrations of albumin and total protein were significantly decreased. Total lipid, cholesterol and triglyceride in the serum were significantly increased. The concentrations of creatinine, BUN, uric acid in the serum, the amount of glucose and occult blood of 24 hours urine were also increased significantly. 2. In the Geumguesingitang group as compared to the Control, the increase in the amount of urinary protein during 24 hours induced by PAN was significantly suppressed, and the concentrations of total protein and albumin in the serum were significantly increased. The concentrations of total lipid, cholesterol and triglyceride in the serum were significantly inhibited. The decrease of the concentrations of creatinine and uric acid in the serum were also observed significantly. 3. In the Dohongsamultang group as compared to the Control, the increase of the amount of protein and glucose of the 24 hours urine induced by PAN were significantly inhibited, and the concentrations of total protein and albumin in the serum were increased significantly. The concentrations of total lipid, cholesterol and triglyceride in the serum were decreased significantly. The decrease of the concentrations of creatinine and uric acid in the serum were observed significantly. It can be inferred that Geumguesingitang has effects on improving proteinuria, hypoproteinemia effectively. It has an effect on hyperlipidemia significantly relieved.

This study was carried out to evaluate the change of blood constituents during the growth of antlers in Korean spotted deer (Cervus nippon). Samples of blood, obtained from the jugular vein of twenty five deer (3 to 6 year-old males) were taken in 10 days interval from casting to cutting of antler and were analyzed the blood parameters. Total-protein concentration in blood serum showed significantly differences during growth period of velvet antler (p<0.01), and it had similar tendency for total protein and albumin concentration, but albumin concentration was about 40-45% of total protein concentration. Urea and creatinine concentration was tended to inverse proportion, and it was almost 30:1 for ratio of urea and creatinine concentration. The concentration of total protein, creatinine, and uric acid concentration in blood during growth period of velvet antler was similarly increased and decreased but urea concentration was opposed. The concentration of total-bilirubin and direct-bilirubin at casting was higher than those at other period(P<0.05).

The present study was designed to assess the protective effect of a selective thromboxane $A_2$ receptor antagonist, KT2-962 (KT2) and possible mechanisms of adriamycin(AD)-induced nephrotoxicity in rats. The male Wistar rats were given either of AD (7.5 mg/kg, i.v.) alone in the AD-group (n=5) or in KT2+AD- group (n=5) which is a combination of AD and KT2 (30 mg/kg/day, i.p.) for 10 days from 3 days before and 7 days after AD injection. The body weight, 24-hours urine volume, urine protein and urinary N-acetyl-$\beta$-D-glu-cosaminidase (NAG) activity were measured with an interval of 2 days during 1 week. BUN, serum creatinine and creatinine clearance were measured on the 7th day. KT2 has significantly suppressed AD-induced change of body weight, 24-hours urine volume, urine protein and urinary NAG activity in the KT2+AD-group. The change of BUN, serum creatinine and creatinine clearance were significantly inhibited in the B7T2+AD-group. Based on these results, it is concluded that KT2 prevents AD-induced nephrotoxicity and suggests that endogenous thromboxane A2 may play an important role in AD-induced nephrotoxicity in rats.

The objective of the current study was to determine factors influencing concentrations of protein-related blood metabolites in indigenous Nguni and crossbred cattle in the semi-arid communal rangelands in South Africa. The body condition scores (BCS), packed cell volume (PCV) and serum concentrations of protein-related metabolites were determined seasonally in 100 cattle raised on communal rangelands from August 2007 to May 2008. Nguni cattle had lower (p<0.05) albumin-globulin ratio, albumin, urea and creatinine, and higher (p<0.05) globulin concentrations than the local crossbreds. Local crossbreds had higher (p<0.05) alanine aminotransferase and alkaline phosphatase concentrations and lower (p<0.05) aspartate aminotransferase concentrations in the postrainy season than Nguni cattle. The creatinine concentrations of Nguni and crossbred cattle were lowest in the sour rangeland during the hot-wet season. The albumin concentrations of Nguni and crossbred cattle were higher (p<0.05) whilst PCV, albumin-globulin ratio and creatine kinase concentration were lower (p<0.05) in the sour rangeland than in the sweet rangeland. Total protein, albumin, globulin, aspartate aminotransferase and creatine kinase concentrations of Nguni and crossbred cattle were lower (p<0.05) in the hot-wet and late cool-dry seasons than in other seasons across rangeland types. Urea concentrations in both breeds were highest in the sweet rangeland in the hot-dry season compared to other seasons. It was concluded that Nguni cattle had lower concentrations of protein metabolites than local crossbreds and protein deficiencies were most prominent in the sweet rangeland during the cool-dry seasons.

This Study was carried out to observe the effect of nutritional condition on the change of protein metabolism in the animal body by feeding on imbalanced protein diet. A total 242 growing male albino rats, weighing $115{\sim}120$ gm, were used for the experimental animals. The rats were fed on the standard diet(st), protein flee diet(pf) and imbalanced protein diet(ib) for twelve weeks respectively. Hemoglobin, packed cell volume in blood, and total nitrogen, amino acid nitrogen, urea-nitrogen, creatinine, transaminases(GPT, GOT) in liver and serum, and total nitrogen in small intestine, and total nitrogen, urea-nitrogen In small intestine, and total nitrogen, urea-nitrogen, creatinine, urea-nitrogen/creatinine ratio in urine were measured. The results obtained are as follows; 1. The gained body weight were lower in pf group and ib group than those of st group. The gained body weight fed for 12 weeks, were 80% lower in pf group than those of st group, and the body weight of pf group for $50{\sim}75$ days feeding were $40{\sim}60%$ decreased, compared with the stating weight, and then all of them died. 2. The change of the brain, liver, kidney, spleen and small intestine by feeding on imbalanced diet for 12 weeks were no remarkable difference with the starting weight, but those of protein free diet group were half or more decrease and those were significantly lower in spleen and small intestine especially than the other organ 3. The contents of hemoglobin in pf group for 8 weeks feeding, and the packed cell volume in pf group for 8 weeks feeding and in ib group for 12 weeks feeding were decreased. but those of the other feeding group were almost same value. 4. The total nitrogen in the liver, small intestine and serum of each diet group were no remarkable difference respectively. The contents of amino acid nitrogen in pf group for 2 and 6 weeks feeding were increased. 5. On transaminases: a) The cycle of increase and decrease of GPT activities were come periodically and the interval of cycle were fast in the early stage of feeding and slow there-after. b) The GPT activities were decreased gradually in pf group after feeding and those were increased in ib group for 6 weeks feeding but decreased there-after. The frequency of cycle were more GPT than GOT and specially those of GPT in early stage of feeding were two or three times while GOT was one. c) The interval of increase and decrease in GOT and amino acid nitrogen cycle were similar tendency. 6. The contents of total nitrogen, creatinine and urea-nitrogen of pf group in urine were decreased very sharply from sharting feeding to one week but increased dully from six weeks to eight weeks feeding. The contents of urea-nitrogen of ib group were increased dully by feeding on ten weeks but decreased by feeding on twelve weeks. From the above results, it is concluded that the trend of the metabolic change is maintained equally by homeostatic mechanism using the endogenous protein source during a certain period by imbalanced protein diet feeding. The homeostatic mechanism is come peridically, very fast in early stage of feeing and than slow there-after.

Some effect on the protein metabolism in growing albino rats by feeding on the rice mixed with wheat or barley have been studied. The species of wheat and barley used in this experiment were either 80% polished or nonpolished wheat, barley and naked barley. The growing rats to be examined were fed on 30% wheat or barley mixed with rice diets for 8 weeks. The total nitrogen, creatinine, amino acid nitrogen and urea-nitrogen contents in the liver and the creatinine and urea-nitrogen contents in the urine have been measured. The results obtained are summarized as follows: 1. The total nitrogen contents in the liver and the serum were no remarkable difference by feeding on each mixed diet, compared with the rice diet group. 2. The creatinine contents in the liver of the unpolished wheat and barley mixed diet groups were the similar to that of the rice diet group, but these were higher by feeding on the polished wheat and barley mixed with rice diets. 3. The amino acid nitrogen contents in the liver of the polished naked barley mixed with rice diet groups were the similar to that of the rice diet group, but these were higher by feeding on the other mixed diets than the rice diet. 4. The urea-nitrogen contents in the serum of the polished wheat and naked barley mixed with rice diet groups were higher than that of the rice diet group, but these were significantly lower by feeding on the polished barley mixed with rice diets than the others. 5. The creatinine and the urea-nitrogen contents in the urine of the original wheat and barley mixed with rice diet groups were higher than that of the polished wheat and barley mixed with rice diet groups. In the view of the above results, it could be seen that the protein metabolism was remarkable change according to polish of the wheat and barley.

Essential minerals are important for human health because they support biochemical reactions in metabolism and may play a role in the development of glucose-6-phosphate dehydrogenase deficiency (G6PD). We investigated the relationship between calcium, magnesium, urea, creatinine, total protein, glucose and vitamin D levels in G6PD deficiency in this study. The control group consisted of 40 people (23 females and 17 males) and the patient group consisted of 50 people (20 females and 30 males), all of whom were between the ages of (1-12 years). The findings revealed that the calcium level in patients, depending on sex factor, has a highly significant increase (p <0.0001) when compared to the control group, especially in children who are females rather than males who are affected by G6PD deficiency. In addition, the level of magnesium was found to be significantly different (p <0.0001) in children male patients when compared to the control group. On the other side, the level of total protein was found to be significantly high in children patients (p <0.01) when comparing with control group, and the levels of urea, creatinine and glucose were found to be highly significant increase (p <0.001) in patients when comparing to healthy groups, vitamin D levels were significantly lower (p <0.0001) with G6PD deficiency comparing to control group. In conclusion, the low and high significant associations between vitamin D, calcium, magnesium, urea, creatinine, and glucose indicate that more research is needed to better understand their roles in G6PD development.

This study aimed to verify the nutritional and curative effects of protein hydrolysate in rats with cysteamine-induced duodenal uncer. Duodenal ulcer rat model was established by intraperitoneal injections of cysteamine. Sprague-Dawley, female rats weighing approximately 200g were intraperitoneally injected twice cysteamine(13mg/100g BW) at intervals of 3h per day. This procedure was repeated 3$\times$at intervals of 3d. Animals fed on 10% casein diet for infection periods. After last injection, 4 kinds of diets(10% casein, 20% casein, 10% casein hydrolysate, 20% casein hydrolysate) were given. Gastric montility, trypsin activity in gastrointestinal content, retention rate of nitrogen, plasma total protein, albumin, amino-N, urinary urea nitrogen, creatinine and hydroxyproline were analyzed for nutritional effects of dietary nitrogen levels(10%, 20%) and sources(casein, casein hydrolysate). In duodenal ulcer rat model, there was no differences between 20% casein diet and 20% casein hydrolysate in the view of severeness of ulcer, gastric emptying rate, serum total protein, serum albumin, plasma $\alpha$-amino-N, UUN, creatinine excretion, GFR, nitrogen retention. On the other hand, rats on 10% casein hydrolysate diet group had more curative effect of the ulcer, higher plasma albumin concentration and nitrogen retention than 10% casein diet group. The casein hydrolysate diet group was lower trypsin activity in small intestinal content than the casein diet group, at both nitrogen levels(10%, 20%). The results suggest that protein hydrolysate be applied in diet therapy for the patients with gastrointestinal ulcer.
