  • This experiment was conducted to study the effects of dietary zinc and ethanol on the mineral contents of serum and changes of the liver tissue. Eighty male rats of Sprague-Dawley strain with average weight of 80$\pm$5g were divided into five groups according to zinc levels(5ppm and 100ppm), ethanol and isocaloric sucrose feedings. The rats were sacrificed after 4 and 7 weeks of feeding periods. The results are summarized as follows. 1. There was a decrease of weight gain in the ZD group compared with the C group and also decreased in the CE and ZDE groups fed the ethanol solution. The feed intake was decreased in the ZD and ZDE groups, and the feed efficiency was also greatly reduced in the ZDE group. 2. The liver weight of the ZD and ZDE groups was increased, however, the weight of testis was decreased in the same groups. And the weight of spleen was decreased in the ZD group. 3. The AST and ALT activities of serum were significantly increased in the ZDE group. 4. The content of serum zinc was influenced by the dietary zinc level, and the amount was significantly decreased in the ZD group. But the content of serum copper was remarkably increased in the ZD grou. The calcium and magnesium contents of serum were decreased in the ZD and ZDE groups. 5. The morphological changes of the liver tissue were not different among the C, CE and PF groups, but the abllooning denaturation of the liver cell together with the infiltration of the local inflammation cell was found in ZD and ZDE groups.

  • Changes of plasma DNA contents and serum biochemical values were measured in rats administered with $HgCl_2$ to investigate the in vivo cytotoxic effects of mercury and examine the usefulness of these changes as indicators of mercury exposure and diagnosis of mercury poisoning. Rats were given once intraperitonealy $HgCl_2$(0.13. 0.32. 0.8 and 2 mg/kg b.w) and the changes of plasma DNA contents and serum biochemical values were measured at the time of 2, 4, 8, 24, 48 and 72 hours after the administration of $HgCl_2$. Plasma DNA contents began to increase from 2 hours after the administration of $HgCl_2$ in all the treatment groups significantly compared to control with dose-dependent pattern. The levels of plasma DNA reached to peak at 48 hours as 2.77, 7.60, 15.46 and 16.51 times higher than control in each treatment group of 0.13, 0.32, 0.8 and 2 mg/kgb.w, respectively and remained to be higher until 72 hours after the administration. The values of creatine kinase, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, blood urea nitrogen and glucose of serum were increased, however the values of alkaline phosphatase, total protein and triglyceride were decreased. These changes of increase and decrease showed dose-dependent pattern but the starting time, maintenance and magnitude of change were various and characteristic according to serum biochemical indices. Among the changes of serum biochemical values, those of aspartate aminotransferase, lactate dehydrogenase and blood urea nitrogen were apparently and significantly increased compared to control from 2 to 72 hours by the administration of 2 mg/kg $HgCl_2$. This study demonstrates that plasma DNA and serum biochemical values such as aspartate aminotransferase, lactate dehydrogenase, blood urea nitrogen and etc. are valuable as biomarkers for mercury exposure assessment and diagnosis of mercury poisoning.

  • This study aimed to determine the effects of adrenalectomy on the sexual gland, the thyroid gland and the serum components. A total of 192 Wister strain albino rats were evenly divided into 4 sexually equal groups for the comparisons. Each groups was divided into a control and a treatment group by sexuality. Each tissue of the sexual gland and the thyroid gland was microscopically examined, and at the same time body weight and serum components were also examined on the 1st, 7th, 14th, 28th, 42nd, 56th, 70th and 84th day respectively following adrenalectomy. The results obtained were as follows: 1. The body weight was sufficiently retarded in decreasingly after the adrenalectomy as compared to that of control. 2. The histological change of testis started atrophy of spermatogonia and degeneration of spermatocyte. There was a, pp.ared no cell division activity. Spermatozoa in the seminiferous tuble was not noticed but degeneration of interstitial cell was started and spermatozoa in the epididymal duct disa, pp.ared. 3. Degeneration of oocyte and follicular cell was noticed as the histological change of ovary. There was not a, pp.arance of primary follicle and corpus Iuteum but interstitial cell was proliferated. 4. For the effect of adrenalectomy on the histological change of the thyroid gland, the number of small follicle decreased and that of large follicle increased as the time passed following the adrenalectomy. And the follicular epithelial cell became squamous as typical condition of functional decreased. 5. It was shown that in the total contents of serum protein no difference with control occurred with in the 70th day for male and female adrenalectomized, respectively. But the differences in protein contents were significanly decreased on the 70th day. 6. No difference occurred in the total serum lipids on the 7th day, but they decreased significantly on the 42nd day, and (P<0.01) on the 56th, and 70th day. A tendency to decrease was noted as time elapsed following adrenalectomy. 7. Increase and decrease were intercrossed in the serum cholesterol contents between the control and th treatment groups on the 28th day. But the difference significantly decreased on the 42nd, 56th, and 70th day after adrelalectomized. The contents showed tendency to decrease as time elapsed following adrenalectomy. 8. The blood glucose contents rapidly decreased with time. The difference were significant on the 28th and 42nd day, and highly significant on the 56th and 70th day for male adrenalectomized. 9. In case of solium, there was no noticeable sexual distinction. There was slight in creasing or decreasing for the control group. But the treatment group tended continuously to decrease for male and female. 10. It was shown that potassium contents tended to increase on the 28th day for male and female, but the differences were small. 11. As for chlorine, it tended to decrease rapidly on 7th day for male and female adrenalectomized, and the tendency continued.

  • Effect of the ingestion of porphyran extracted from Porphyra yezoensis on calcium, magnesium and potassium contents in serum and tissue was investigated using hyperlipidemic and hypercholesterolemic rats. The contents of calcium magnesium and potassium in serum of rats fed porphyran for four weeks were higher than those of the control group. The contents of calcium and potassium were decreased with increasing a porphyran level while magnesium content was increased. Liver calcium contents in an $1\%$ porphyran group were significantly (p<0.05) higher than those in the control group, and magnesium contents in a $10\%$ porphyran group were higher than those in the control group. Kidney calcium and magnesium contents in rats fed porphyran were significantly (p<0.05) high compared with the control group. However, potassium content in kidney was Increased as a porphyran level was increased in diet. Spleen calcium and potassium contents were significantly lower in the porphyran groups than those in the control group. Rats fed the $5\%$ porphyran diet had higher magnesium content in spleen than any other diets. The results showed that diets supplemented with several porphyran levels had variable effects on the contents of calcium, magnesium and potassium in serum and tissue of hyperlipidemic rats.

  • Objectives The object of this study was to observe the effects of Hyeongbangjihwhang-tang (HB; Soyangin prescription) on the 5/6 NTX induced CRF rats. Methods Each of Hyeongbangjihwhang-tang aqueous extracts 200mg/kg were orally administered once a day for 35 days from 4 weeks after 5/6 NTX surgery. Four groups, each of 8 rats per group were used in this study, were sham group, CRF group, ${\alpha}$-Tocoperol group and HB group. Changes on the left remnant kidney weights, serum BUN, creatinine levels, caspase-3, PARP immunoreactivities were observed to nephroprotective effects, and relative immunomodulatory effects were monitored based on the changes of lymphatic organ weights and splenic cytokine contents. In addition, the changes on the kidney MDA, GSH contents and SOD, CAT activities were also calculated for antioxidant effects, and the effects on the CRF related cachexia were demonstrated based on the changes of body and epididymal fat pad weights, serum TG, TC, LDL and HDL levels. Results and Conclusions 1) HB was significantly decreased the left remnant kidney weights, serum BUN, creatinine levels and caspase-3, PARP immunoreactivities. 2) HB was significantly increased lymphatic organ weights and splenic cytokine contents. 3) HB was significantly increased body and epididymal fat pad weights, and was significantly decreased serum TG, TC, LDL and HDL levels. 4) HB was significantly decreased MDA contents, and was significantly increased GSH contents and SOD, CAT activities. The results obtained in this study suggest that HB significantly retarded immunosuppressions and cachexia related to the 5/6 NTX induced CRF through modulations of oxidative defense systems. Especially HB showed the highest favorable effects more than those of ${\alpha}$-tocoperol.

  • This study examined the effect of dietary lipids and guar gum on lipid metabolism in ovariectomized rats. The experimental animals received ovarietomy (OVX). Lipids sources were divided into 3 groups (soybean oil(SB), beef tallow(BT)) and fish oil(FO)) and guar gum was supplemented to each lipid diet (SBG, BTG, FOG). Experimental diets were fed to therats for 16 weeks. Serum triglyceride (TG) levels were higher in the BT group and lower in the FO group as compared to the SB group .Serum total cholesterol (Tc) and HDL-C levels were lower in the FO group as compared to the SB group. Serum LDL-C and phospholipid levels were lower in the FO group as compared to the SB group. Serum lipids levels were lowered by guar gum supplement. Serum SFA(saturated fatty acids) contents were not significantly influenced by dietary lipids and guar gum. Serum MUFA(monounsaturated fatty acids) contents were the lowest in the SB group. Fecal weight was highest in the beef tallow group and lowest in the fish oil group. Fecal weight was increased by guar gum supplement in all lipid groups. Total bile acid content in feces was increased by guar gum supplement in the soybean oil and beef tallow groups. The endothelial cells of the beef tallow group changed from a flat shape to distorted round and enlarged shapes. The subendothelial layer was the thickness the thickest in the beef tallow group ; the interspace between elastic lamina was widened and elastic lamina was straightened and partly disrupted . The fish oil group showed more porminient endothelial cells and subendothelial layer. Internal elastic membrane and elastic lamina exhibited regularly wavy shapes. Guar gum supplement showed positive effects in all lipids groups. Based on the above results , it is suggested that beef tallow increased serum TG levels and injured the wall of the aorta. On the other hand, fish oil , which decreased serum lipid levels, has a positive effect on the walls of the aorta. Guar gum protects the aorta from injury by reducing the serum lipid levels. Therefore, it is suggested that soybean oil and beef tallow consumed with guar gum is beneficial.

  • To compare the extent of heat treatment in domestic infant formula, pH,titratable acidity, undenatured whey protein contents, HMF contents and protein-reducing substances of three commercial products (A, B, C) were measured. The pH of B products was lowest and the titratable acidity of B product was highest. The contents of undenatured whey protein per 100ml serum were 0∼30mg(A products), 90∼130mg(B products)and 80∼90mg(C products), respectively. Distinct differences of undenatured whey protein contents according to the manufacturer and infat's stage in age could be observed. The HMF contents of tested products showed 10.9∼21.5umol/L and B-2 product(B products for the second stage of 5∼9 month) was the highest among tested products. The protein-reducing substances showed 4.46∼9.50mg K4Fe(CN)6/100ml serum nd B-2 product was the highest among tested products.

  • This study was divised to observe the effects of ginseng on the body components of Sprague-Dowley Albino male rats by alternating the diet. Just weaned rats (130 heads, weighing(83 ${\pm}$ 4g) were fed with each stock diets supplemented with 0.5, 1.0 or 3.0% ginseng powder for 4 weeks or 8 weeks, and after that fed with stock diet only for 8 or 4 weeks. Compared with the each corresponding group which was fed with ginseng control diet, the protein, total lipid, total cholesterol and free cholesterol contains in serum, liver and aorta of them were determined. The results obtained was summarized as follows ; Protein and total lipid contents of the rat were decreased, caused by the alternating diets, but total cholesterol and free cholesterol contents were increased in the serum, protein and free cholesterol contents increased, conversely total lipid contents decreased in the liver, and in aorta total lipid and total cholesterol contents decreased, In the view of the above results, it can be seen that the alternating diet (stock diet after feeding with ginseng diet) has an influence on the body components of rat.
