This study was designed to observe the efficacy of Boyangsengjang-Tang(BST) on the growth of rats. The effects on growth, and the secretion of hormones in the serum was measure. Male BALA/C mice(weight 20-25g), and male ICR rats(weigh 120-150g), were each divided into 3 groups : Sample A, Sample B and a Control group. Each group consisted of 4 mice and 5 rats. Mice received $5{\mu}{\ell}$ BST, and rats received $50{\mu}{\ell}$ BST, daily. Sample A was administered with normal BST for 3 weeks. Sample B was was administered with 10 times the normal amount of BST for 3 weeks. Control group was administered with normal saline for 3 weeks. The body weight, body length, subcutaneous fat, length of femur, serum GH, serum IGFBP-3 and serum in TSH were measured at 1, 2, and 3 weeks. The results were as follows ; 1. The body weigh of the rats increased significantly in Sample A after 3 weeks when compared with control group. 2. The body length in rats increased significantly in Sample A when compared with control group. 3. The amount of subcutaneous fat in the mice increased significantly in Sample B after 1 week when compared with control group. The amount of subcutaneous fat in rats increased significantly in Sample A and Sample B after 3 weeks when compared with the control group. 4. The length of the femur in rats increased significantly in Sample in A and Sample B in 1, 2, and 3 weeks when compared with the control group. 5. The level of GH, IGFBP-3 and TSH in the serum was not statically different when compared with the control group. According to the above results, BST (which reinforces the Kidney's Yang and strengthens muscle and bone) increases body weight, body length, subcutaneous fat and the length of the femur when compaired with the control group. BST therefore seems to improve growth.
This study was performed to investigate the effects of lead poisoning and different levels of dietary lipid on lead and lipid metabolism in the rats. Forty eight male weanling rats of Sprague-Dawley strain weighing 73.1$\pm$11.1g were blocked into 6 groups according to body weight. Dietary lipid were given at the lev딘 of 5, 20 and 40% of total caloric intake and lead were either administered or not. The results obtained are summerized as follows ; 1) Food intake, weight gain, F.E.R. liver and epididymal. fat pad weights, weight and length of bone, hematocrit and hemoglobin content in Pb-adminstered groups were lower than these in Pb-free groups. 2) Plasma lipid and cholesterol levels were tended to be higher in Pb-administered groups than in Pb-free groups, while liver lipid and cholesterol levels were tended to be lower in Pb-adminstered groups. 3) Fecal dry matter excretion was tended to be higher in Pb-adminstered groups than in Pb-free groups, and were increased with increasing dietary lipid level. Daily fecal excretions of lipid and cholesterol were higher in high lipid groups than in low lipid groups and these levels were even higher in the animals exposed to Pb than in Pb-free groups. 4) Pb contents in blood, liver, kidney and bone were significantly higher in Pb administered groups than in Pb-free groups. Pb levels of blood, liver and bone did not show any significant difference among groups with different levels of dietary lipid, but Pb concentration in kidney of Pb-adminstered groups increased with increasing dietary lipid level.
C-type lectins are crucial for pathogen recognition, innate immunity, and cell-cell interactions. In this study, a C-type lectin gene was cloned from the rock bream. The full-length RbCTL cDNA was 729 bp with a 429 bp ORF encoding a 164-residue protein. The deduced amino acid sequence of RbCTL had all of the conserved features crucial for its fundamental structure, including the four cysteine residues involved in sulfide bridge formation and potential $Ca^2+$/carbohydrate-binding sites. RbCTL contains a signal peptide one single carbohydrate recognition domain. It showed 29.4% similarity to the C-type lectin of rainbow trout. RbCTL mRNA was predominately expressed in gill and head-kidney tissue and expressed less in peripheral blood leukocytes, trunk-kidney, spleen, liver, intestine and muscle. Expression of RbCTL was differentially upregulated in rock bream stimulated with LPS, Con A/PMA and poly I:C.
This experiment was conducted to determine and compare some characteristics of the meat and carcass of rabbits aged 11 weeks according to sex. In the experiment thirty male and thirty female New Zealand White rabbits were slaughtered. The weights and percentages of cold carcasses, skin with head and limbs, liver, kidney, heart, lung, fore legs, hind legs, breast and ribs, loin and abdominal wall were recorded. The values for carcass length, lumbar circumference, pH in the muscles of Biceps femoris and Longissimus dorsi, meat to bone ratio and cooking loss were also determined. The mean values for cold carcass weight and cold dressing percentage were 832 g and 48.77% in male and 849 g and 48.69% in female, respectively. In this study no significant differences were shown between male and female rabbits in the characteristics of carcass and meat except the value of pH of Longissimus dorsi muscle which was markedly higher in males than that in females meat. Slaughter weight was positively correlated with the weights of carcass, skin with head and limbs, lung, liver, kidney, heart and weights of joints (p<0.01) and dressing percentage (p<0.05).
The objective of this study was to describe a radiofrequency (RF) coil design for in vivo sodium magnetic resonance imaging (MRI) for use in small animals. Accumulating evidence has indicated the importance and potential of sodium imaging with improved magnet strength (> 7T), faster gradient, better hardware, multi-nucleus imaging methods, and optimal coil design for patient and animal studies. Thus, we developed a saddle-shaped sodium volume coil with a diameter/length of 30/30 mm. To evaluate the efficiency of this coil, bench-level measurement was performed. Unloaded Q value, loaded Q value, and ratio of these two values were estimated to be 352.8, 211.18, and 1.67, respectively. Thereafter, in vivo acquisition of sodium images was performed using normal mice (12 weeks old; n = 5) with a two-dimensional gradient echo sequence and minimized echo time to increase spatial resolution of images. Sodium signal-to-noise ratio in mouse kidneys (renal cortex, medulla, and pelvis) was measured. We successfully acquired sodium MR images of the mouse kidney with high spatial resolution (approximately 0.625 mm) through a combination of sodium-proton coils.
This study investigated the effects of chitosan on mineral metabolism in rats exposed to cadmium by oral administration. Six week-old Sprague-Dawley rats were divided into eight groups. Four groups were fed AIN-93G based 3% ${\alpha}$-cellulose diets and the other four groups were fed 3% chitosan diets for four weeks with the oral administration of 0, 0.5, 1.0, 2.0 mg Cd/2ml distilled water three times per week, respectively. The essential mineral contents of serum, liver, kidney and bone (femur and lumbar), and the excretion of calcium in feces and urine were determined. There was no significant difference in weight gain and food intake among groups. The cadmium administration significantly decreased calcium in serum, iron in blood, calcium and iron in liver and iron contents in kidney. In contrast, calcium and zinc contents in kidney increased by the administration of cadmium. The weight, length and breaking forces of the femur and lumbar were not significantly different due to cadmium administration and chitosan among the groups. The fecal excretion of calcium was increased by the administration of cadmium. On the other hand, calcium absorption and the absorption rate were decreased by Cd administration. In the groups without Cd administered (N, N-Chi groups), chitosan significantly decreased the absorption rate of calcium by increasing the excretion in feces (p<0.05). These results suggest that cadmium administration may facilitate the decline of essential minerals in rats and also, chitosan may have a conflicting effect between cadmium and the essential minerals of tissues.

Whole-body insulin resistance results largely from impaired insulin-stimulated glucose disposal in skeletal muscle. Our previous studies using differential display and quantitative real-time RT-PCR have shown that a novel cDNA band (DD23) had a higher level of expression in insulin resistant skeletal muscle and it was correlated with whole-body insulin action, independent of age, sex, and percent body fat. In this study, we cloned and characterized DD23. The DD23 sequence is part of the 3'UTR region of the RNA binding motif, single stranded interacting protein (RBMS3). We have cloned the full length cDNA for RBMS3 and identified two splice variants. These variants named DD23-L and DD23-S have 15 and 14 exons respectively and differ from RBMS3 in the 3'UTR significantly. Northern blot analyses showed that an ~8.8 kb mRNA transcript of DD23 was predominantly expressed in skeletal muscle and to a lesser extent in placenta, but not in heart, brain, lung, liver, or kidney, unlike RBMS3. Elevated expression levels of these novel alternatively spliced variants of RBMS3 in skeletal muscle may play a role in whole body insulin resistance.

Purpose: This study aimed to evaluate the clinical findings in pediatric rhabdomyolysis and the predictive factors for acute kidney injury (AKI) in Korean children. Methods: Medical records of 39 Korean children, who were newly diagnosed with rhabdomyolysis from January 2008 to December 2015, were retrospectively analyzed. The diagnosis was made from the medical history, elevated serum creatinine kinase level >1,000 IU/L, and plasma myoglobin level >150 ng/mL. Patients with muscular dystrophy and myocardial infarction were excluded. Results: The median patient age at diagnosis was 14.0 years (range, 3-18 years), and the male to female ratio was 2.5. The most common presenting symptom was myalgia (n=25, 64.1%), and 14 patients (35.9%) had rhabdomyolysis-induced AKI. Eighteen patients (46.2%) had underlying diseases, such as epilepsy and psychotic disorders. Ten of these patients showed rhabdomyolysis-induced AKI. The common causes of rhabdomyolysis were infection (n=12, 30.7%), exercise (n=9, 23.1%), and trauma (n=8, 20.5%). There was no difference in the distribution of etiology between AKI and non-AKI groups. Five patients in the AKI group showed complete recovery of renal function after stopping renal replacement therapy. The median length of hospitalization was 7.0 days, and no mortality was reported. Compared with the non-AKI group, the AKI group showed higher levels of peak creatinine kinase and myoglobin, without statistical significance. Conclusion: The clinical characteristics of pediatric rhabdomyolysis differ from those observed in adult patients. Children with underlying diseases are more vulnerable to rhabdomyolysis-induced AKI. AKI more likely develops in the presence of a high degree of albuminuria.

Excluding an operation remedy about an example of Traumatic Cervical Stenosis patient, by doing pattern identification such as blood stagnation in hospitalization for the early days and such as the stagnation of Oi for the middle days and such as Eum deficiency of liver and kidney for the last. We have done treatment by being based on method of therapy to promote blood flow to remove blood stasis and to promote the normal flow of Oi and to nourish the liver and the kidney. In result, we had remarkable conclusion and considered that we had to treat a patient like that appropriately by distinguishing & making a diagnosis correctly from now on. If we apply clinically by thinking of Oriental Medicine through more example of symptoms, we have considered that it will serve as a momentum that we can sympathize with the excellency of Oriental Medicine. In the future, we have considered that have to be necessary to make more researches and reports upon it.
This study was performed to validate the procedure of transarterial embolization of the renal artery (TAE-RA) using iohexol-ethanol solution in dogs with unilateral experimental hydronephrosis and to evaluate the embolized kidney using B-mode ultrasonography and selective angiography. Experimental hydronephrosis was induced by ligation of unilateral ureter in 12 dogs. Ultrasonographic findings revealed that size of the kidney was significantly increased at 9 days and 17 days and the length of renal cortex was significantly decreased at 17 days after ligation of the unilateral ureter and it was in accordance with dilation of ipsilateral renal pelvis. No significant change of BUN, creatinine, ALT, calcium, and phosphorus was found immediately after unilateral experimental hydronephrosis. Therefore, it was concluded that unilateral hydronephrosis was established in 12 dogs at 17 days after ligation of ureter. Renal artery embolization was performed using selective catheterization in the hydronephrotic kidney of seven dogs and EKG, $SpO_2$, body temperature, pulse, and respiratory rate were within normal ranges during procedures. Iohexol-ethanol solution was used as embolic material. Average ethanol dose for renal artery embolization was $1.94{\pm}1.24ml/kg$. There were no dogs expired after TAE-RA and no side effects associated with regurgitation of iohexol-ethanol solution. Revascularization of renal artery was not found in angiography in dogs treated by TAE-RA at immediately after TAE-RA and 14 days after TAE-RA. Ultrasonographically, the mean longitudinal length of the embolized kidney decreased significantly at 2 and 3 months after TAE-RA compared to that of contralateral normal kidney. In summary, marked shrinkage of the embolized kidney was observed in dogs with unilateral experimental hydronephrosis treated by TAE-RA with iohexol-ethanol and no adverse effects were observed throughout the observation period. It is concluded that TAE-RA with iohexol-ethanol solution is a viable alternative to nephrectomy in dogs with unilateral hydronephrosis.
