This dissertation is try to figure out why chestnut belongs to kidney channel, from the viewpoint of five elements theory. After studying chestnut's property, flavor, channel tropism, main cure ability, prescriptions, shape, sweet, and prohibitions, I came to the following results. 1. Property of chestnut is warm and has no toxicity, so it is less related than kidney property. 2. Flavor of chestnut is salty and sweet, so it has some relation to kidney and spleen properties. 3. Channel tropism of chestnut enters mainly into kidney channel, and then spleen and stomach channels. 4. Chestnut controls kidney function of storing the essence of life, determining the condition of bone and marrow, conduction water metabolism, affecting reasoning activity, and controls activity of nine openings of body. It also has effects on functions of spleen, intestines and stomach. 5. Prescriptions including chestnut is similar to that of human brain, it is possible to reason out that chestnut has some relation to human brain. 7. As flavor of chestnut flower is similar to that of spermatic fluid, so it has som relation to kidney property. 8. As chestnut has property of blocking qi and it causes spleen, stomach and colon system to be confused, so it is suggested that persons with weakende spleen and stomach be not allowed to take in.

In recent years, the prevalence of type 2 diabetes mellitus has dramatically increased in Korea as the diet has rapidly become westernized. We determined the effect of long-term cola intakes on glucose metabolism and oxidative stress in weanling male Sprague Dawley rats consuming a moderate fat diet Thirty male rats, born from 6 female rats, were randomized into cola or water drinking groups. For 28 weeks, all rats were provided with an ad lib solid diet having 33 percent of its metabolisable energy as fat In addition, rats of the cola group were provided with ad lib cola instead of water. The daily total caloric intake did not differ between groups. The rats in the cola group consumed a higher proportion of carbohydrates, and their mean body weight and fasting serum insulin level were lower than that of the control group. Whole-body glucose disposal rates measured by an euglycemic hyperinsulinemic clamp were higher in the cola group. However, lipid peroxide levels in kidney tissue were higher in the cola group than in the control group. Superoxide dismutase activity in kidney tissues was lower in the cola group compared to the control group, while glutathion peroxidase and catalase activities were not significantly different between the two groups. In conclusion, long-term cola intakes decreased insulin resistance, but increased oxidative stress in kidney tissue due to decreased SOD activities, which may lead to kidney damage. Thus, moderate changes in insulin resistance may not affect the status of oxidative stress, and vice versa.

This study was conducted to investigated the short-term effects of early weaning and protein intake on organ and cell growth, nitrogen metabolism and physiological functions of rats. Five groups of early weaned rats separated from the dam on the 15th day postpartum were each given one five diets consisting of either one of the three levels of casein-low(8%), -normal (16%), and -high(32%), or a normal level (16%) of isolated soy protein(ISP) or egg yolk protein, for 7 days. The normal weaned rats were fed maternal breast milk for three weeks from birth. On the 22nd day postpartum , all the rats were sacrificed . The weight gain of the early weaned rats, especially the ones fed high protein, was observed to be significantly lower than that of the normal weaned rats. By the 15th day, of early weaning and especially in the ISP-fed rats, the total DNA contents of liver and kidney, which may be said to represent an index of cell numbers, significantly decreased, but their fresh and dry weight and protein/DNA ratio, allegedly representing an index of cell size, significantly increased , not affecting the cell number and cell size of brain. There were no differences in total serum protein and albumin concentrations between early and normal weaned rats. In the early weaned rats observed , the serum urea N and $\alpha$-amino N concentrations significantly increased in high protein-fed rats, and decreased in low protein-fed rats. Another observation was that no significant difference was noticed as regards to serum GOT activity, total bilirubin, uric acid, and creatinine concentration, which may represent indices of liver and kidney functions, among rat groups, GPT activity was an exception . These results suggest that premature weaning and the quality and quantity of dietary protein significantly affect organ and cell growth and nitrogen metabolism but does not seriously affect physiological functions in the neonatal development of rats.

This study was performed to investigate effect of dietary fibers in rice and barley on glucose, lipid and cadmium (Cd) metabolism in the rat. Fifty-six male Spague-Dawley rats weighing 244.6$\pm$2.7g were blocked into eight groups according to body weight and raised for four weeks with diets containing 0 or 0.04%(w/w) CdCl2 and four different carbohydrate sources, starch, rice flour, barley flour and mixture of rice and barley flour(7 : 3, w/w). Total dietary fibers and $\beta$-glucan contents of barley were about three times higher than those of rice (10.75% vs. 3.94%, 3.11% vs. 1.06%, respectively). Food intake, weight gain, food efficiency ratio, liver and kidney weights were lower in Cd exposed groups, and barley group among Cd exposed animals showed highest weight gain, food efficiency ratio and organ weights. Fasting serum glucose levels were not significantly different among groups, Serum cholesterol level was lowest in Cd exposed barley group. Serum HDL-cholesterol level was higher in none-Cd exposed starch and barley groups, and HDL-cholesterol : total cholesterol ratios were higher in none-Cd rice and mixed flour groups than other groups. Liver total lipid and triglyceride levels were lowest in barley groups regardless of Cd administration. Fecal total lipid, cholesterol and triglyceride excretions were high in barley and mixed flour groups. Liver Cd concentrations were low in Cd exposed barley and mixed flour groups. In Cd exposed barley group, fecal weight and Cd excretion were highest and Cd retention ratio was lowest among groups. Small intestine metallothionein(MT) concentration was highest in Cd exposed rice group, and kidney MT concentration was highest in Cd exposed barley group. In conclusion, cereals showed different effects on lipid and Cd metabolism that might be mediated by dietary fibers in cereals. Especially $\beta$-glucan-rich barley group showed greatest lipid and Cd lowering effects by increasing fecal lipids and Cd excretions.

The kidneys are exposed to toxicants and waste product and can be affected easily by these toxicants and by products of the metabolism. The consumption of adequate water is necessary to remove waste and to keep kidney healthy. Deficiency of liquid in the blood leads to various adverse effects on the kidney. The most common adverse deficiency of liquid in blood is deposition of solid matter in the kidney and subsequently formation of kidney stone. Nephrolithiasis (kidney stone) can be treated by drugs if it is small in size but if it blocks the route due to its big size then surgery is the only way to remove it. The recurrence rate of the problem is very high and it may reappear within 10 years. In Unani literature Hasāh wa Raml al-Kulya (nephrolithiasis) is described in detail. As per Unani literature stagnation of Ghalīz mādda (filthy and viscous matter) in the kidney is the main cause of the formation of kidney stone. Various single and compound formulations drugs are described for the management of kidney stone which are very effective as well as safe. Management is divided into two parts i.e. symptomatic treatment to relieve pain and to methods adopted to remove stone from the kidney. Musakkin-i-Waja'(analgesic) drugs are used for pain while Mufattit-i-Hasāh (lithotriptic) and Mudirr-i-Bawl (Diuretic) drugs are used to remove stone. Majoon Aqrab, Qurs Kaknaj and Dawa-e-Gurda etc. are compound drugs mentioned in literature for removal of kidney stone. Single drugs like Alu Balu, Tukhm Khayar, and Kharkhask etc. are also used for same purpose.

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.

A 22-year-old male patient was diagnosed with autosomal dominant polycystic kidney disease (ADPKD). He received conservative treatment with an angiotensin-converting enzyme inhibitor. Two years later, oral therapy, consisting of 60 mg tolvaptan per day, was initiated. Compared with height-adjusted total kidney volume, the rate of kidney growth reduced significantly from 7.33% to 0.66% annually, since commencement of the tolvaptan therapy. The liver enzyme profile and serum sodium level and osmolality were constantly within normal ranges. In Korea, this is the first reported case of a patient with ADPKD who received tolvaptan treatment for more than 1 year. This case demonstrates that long-term tolvaptan treatment appears to be safe, well tolerated, and effective for ADPKD.

Mitochondria was observed much around the nuclear membrane of liver tissue where the energy metabolism process is active. Testis tissue had a large number of undifferentiated cells, and cristae in Inner membrane of Mitochondria was not observed clearly. Morphological damage occurred first in Inner membrane rather than the outer membrane. The kidney tissue was clearly observed in the form of cristae. Radiation-induced damage occurred at the edges of both ends, and the membrane was observed bursting with the thickness of the outer membrane. Small intestine cells were observed in many mitochondria in the tissues around the villus, where bowel movements were active. Morphological damage occurred with the outer and inner membranes getting tangled. Mitochondria sensitivity to radiation was sensitized in testis and small intestine tissues, and kidney, ovary and liver tissues were found to be resistant.

This study was conducted to investigate the effects of brown rice and brown rice phytosterol on blood pressure and lipid levels in spontaneously hypertension rats (SHR). SHR were grouped according to blood pressure and fed either a control diet or experimental diets containing 50% brown rice powder or 5% brown rice phytosterol for 3 weeks. Body weight gain and epididymal fat weight were significantly reduced in the brown rice powder and brown rice phytosterol groups compared to control. Brown rice and brown rice phytosterol diets suppressed age-dependent increases in systolic blood pressure compared to control. In addition, brown rice and brown rice phytosterol diets decreased total lipid, triglyceride, and cholesterol levels in the liver, whereas serum HDL cholesterol increased. Lastly, brown rice phytosterol reduced TBARS contents in the kidney. These results suggest that brown rice and brown rice phytosterol exert antihypertensive effects that improve lipid metabolism in SHR.

The purposes of this article are understanding the meaning of yin deficiency interpreted with a perspective of Traditional Korean Medicine and a modern perspective a study and assigning modern diseases to yin deficiency pattern types. Clinical papers were searched in China National Knowledge Infrastructure(CNKI) from 1995 to 2013. Results are as follows. First, yin deficiency written in the "Neijing" has been understood in many ways. It is translated such as deficiency of yin qi, inner qi, essence, cubit pulse, yin meridians qi, viscera yin and kidney. Second, yin deficiency pattern are related with disorders of the endocrine system, immunity, energy metabolism, blood circulation, cytokine, microelements, lipid metabolism and capability of getting rid of oxygen free radicals. Third, from pattern types, diverse diseases classified in types involving the heat from yin deficiency, which reflects pathologic conditions of deficiency heat which is distinct characteristics of yin deficiency pattern. Various diseases classified in types related with liver or kidney are reported, which reflects two viscera are more related with yin deficiency than other viscera. Fourth, levels of pattern types surveyed are more specific than Korean Standard Classification of Diseases(KCD) and specific enough to be applied clinically. This article surveyed the categories of modern diseases yin deficiency pattern types is assigned to but the detailed relation between them will be necessary to be studied in the future.
