  • When we see normal gait, gait cycle is seperated as stance phase and swing phase. It needs 6 determinant of gait of pelvic rotation, pelvic tilt, knee joint of stance phase, ankle and foot motion, ankle and knee motion, and pelvic movement to be accomplished. In addition, a joint and muscle action is accomplished biomechanically at the same time with its gait cycle. In oriental medicine, the relationships between chang-fu physiology and meridian physiology are summaried as follows ; ${\bullet}$ chang-fu physiology : Spleen manages the extremities. Liver manages soft tissues. Liver stores blood. Kidney stores essences. Kidney manages bones. ${\bullet}$ meridian physiology : The Leg Greater Yang Meridian and meridian soft tissues The Leg Yang-Myeong Meridian and meridian soft tissues The Leg Lesser Yang Meridian and meridian soft tissues The Leg Greater Yin Meridian and meridian soft tissues The Leg Lesser Yin Meridian and meridian soft tissues The Leg Absolute Yin Meridian and meridian soft tissues Especially, we can find out relations between in a "blood supplied feet can walk well" that explains "blood regulations and by liver nourishing effects"that is the closest concept of muscle. Abnormal gaits are due to three causes as following; first, physical defect secoud, pain third, nervous system or instability of muscle. In oriental medicine, we can know relationship in "atrophy, numbness, stroke, convulsion, muscular dystrophy of knee, rheumatoid arthritis, five causes of infantile growing defects, five causes of softening, sprain". Especially, atrophy is the most important symptom. Gait evaluation should be emphasized where a point can walk 8 feet to 10 feet considering stride width, stride length, the body weight center, stride number, flexion, extension, rotation of a joint as a standard factor. The point is we should find out something strange in a patient's side, front and back view. After that we should find out its cause as an index that we can observe abnormal findings in a joint and muscle.

  • Based on the soft and rigid extents, tissues are mainly divided into two groups in mammals, soft tissues including heart, lung, kidney and brain, and hard tissues including tendon, cartilage, teeth and bone. Among various tissues, bone, a dynamic rigid organ, is continuously remodeled by the opposing functional activity between bone formation by osteoblasts and bone destruction by osteoclasts. Bone protects the soft tissues and provides mineral reservoirs, which can supply the mineral needs of other soft tissues to normally maintain cellular function. While calcification in bone is an important action to fundamentally support the body and protect the soft tissues, calcification in soft tissues, including the heart, aorta, kidney, lung and spleen, results in severe organ damages, eventually causing sudden death. A growing body of evidence indicates that the osteoporotic patient who are aging, post-menopausal, diabetes and chronic kidney disease simultaneously represent a high clinical incidence of soft tissue calcification, illustrating a link between soft tissue calcification and bone decalcification (osteoporosis). This study will review what is currently known about the connection between bone decalcification and soft tissue calcification.

  • The purpose of this study was to evaluate detecting methods and the relationship between tissues and blood for enrofloxacin and metabolic ciprofloxacin residues in broiler chickens. Two groups of broiler chickens were administrated via the drinking water with $50{\mu}g/mL$ and $100{\mu}g/mL$ of enrofloxacin for 5 days, respectively. The concentration of enrofloxacin and metabolic ciprofloxacin in tissues (muscle and kidney) and blood were measured during administration period (for 5 days) and withdrawal period (for 12 days) by high performance liquid chromatography (HPLC) method. Also, all samples were conducted for screening of residues by microbial method using E. coli for quinolone detection and immuno-chromatography method using Smart kit. The relationship between tissues (muscle and kidney) and blood for enrofloxacin and metabolic ciprofloxacin residues in broiler chickens was followed : The levels of enrofloxacin and metabolic ciprofloxacin residues in muscle and kidney were higher 2.9~3.2 folds, 3.6~3.8 folds more than the residues levels in blood, respectively. These results support we can predict the residues in muscle and kidney from the residues in blood. In comparison of detecting methods for antibiotic residues, microbial method using E. coli for quinolone detection and immuno-chromatography method using Smart kit could detect positive reaction at similar or lower concentration than violative concentration of enrofloxacin and metabolic ciprofloxacin in chicken tissues. These results support what two screening methods are useful for screening of quinolone detection in chickens.

  • Tissue homogenates of Ehrlich ascites tumor tissues and several normal tissue of mice were incubated separately in medium maintaining $C^{14}$_acetate concentrations of 5, 10, 20, 30, 40, 50 and 60 mg%, in order to determine maximum oxidative rates of acetate. In every incubation experiments, respiratory $CO_2$ samples rapped by alkaline which was placed in the center well of the incubation blask were analyzed for total $CO_2$ Production rates and their radoactivies. The fractions of $CO_2$ from medium acetate to total $CO_2$ production rate were obtained with relative specific activities (RSA) which were calculated by ratio between specific activities (SA) of $CO_2$ and medium $CO^{14}$_acetate and $CO_2$ production rates from medium acetate were calculated from RSA and total $CO_2$ production rates. Maximum plateau values of oxidative rates described above were determined at incubation experiments of various concentrations of medium acetate and compared the oxidative rates of acetate of tumor with those of normal tissues such as kidney, brain and liver. Maximum plateau values of total $CO_{2}$ Production rates were obtained at acetate concentration of 20 mg% and represent $25.0{\pm}0.54\;{\mu}M/hr/gm$ in the brain, $16.3{\pm}2.5$ in the kidney, $9.1{\pm}1.78$ in the liver and $11.5{\pm}3.2\;{\mu}M/hr/gm$ in the ascites tuners. Substancial $CO_2$ yield was observed in the tumor tissues as in the normal tissues. On the other hand, plateau values of RSA were $25.7{\pm}1.04%$ in thee brain, $9.1{\pm}0.72%$ in the kidney, $2.5{\pm}0.73%$ in the liver and $0.51{\pm}0.12%$ in the tumor tissues. $CO_2$ yields from the medium acetate, were 4.19 in the kidney, 2.28 in the brain, 0.228 in the liter and $0.059\;{\mu}M/hr/gm$ in the tumor tissue. These show wide range even in the normal tissue but remarkable decrease in the tumor tissue. This fact means that further oxidation of acetate was inhibited remarkably in the tumor tissue.

  • Whether there exists a sympathetic neural regulation on the aquaporin (AQP) channels in the kidney was examined. Male Sprague-Dawley rats were used. They were renal nerve denervated by stripping the nervous and connective tissues passing along the renal artery and vein, and painting these vessels with 10% phenol solution through a midline abdominal incision. Three days later, the expression of AQP1-4 proteins in the denervated kidneys was determined. The content of norepinephrine was found significantly decreased following the denervation. Accordingly, the expression of AQP2 proteins was markedly decreased. The expression of AQP3 and AQP4 was also slightly but significantly decreased, while that of AQP1 was not. Neither the basal nor the AVP-stimulated accumulation of cAMP was significantly affected in the denervated kidney. It is suggested that the sympathetic nervous system has a tonic stimulatory effect on AQP channels in the kidney.

  • Present study aimed to investigate the effect of zinc accumulation on the tissues of Carassius auratus with various rearing condition. Heavy metal, Zn, was accumulated in the gill, bone and muscle increased for exposure period of 40 days. Moreover, the accumulated concentration of Zn in the gill showed relatively higher than that in other tissues. Also, activities of antioxidant enzymes in the gill, kidney, liver and muscle tissues after exposure to Zn were increased in the manner of exposure period. Antioxidant enzyme activities were shown higher in the gill and muscle than those in the kidney and liver tissues. The gill of C. auratus showed abnormal shapes in its secondary lamellae by long time exposure condition and determined the increased numbers of mucous cells in gill exposed to Zn. In addition, the edema, the exfoliation of epithelial cell was shown in the gill and membrane damages were observed in mitochondria and nucleus. In the kidney, we observed not only the atrophied glomerulus, but the expansion of empty space in Bowman's capsule. Based on the above results, it is considered that the exposure to the high level of Zn for long period possibly involves in the decrease of respiratory and excretory rates, giving rise to secondary lesion of tissues.

  • Spirochetes were isolated from the midgut of Ixodes persulcatus ticks captured at Chungju, Korea and identified as Borrelia afzelii strains by polymerase chain reaction. To determine the pathogenicity of the B. afzelii strains isolated in Korea, the microbiological and pathological features of Lyme disease were observed in C3H/He mice after intraperitoneal inoculation of the fresh isolate of B. afzelii strain. The results are summarized as follows 1) The Borrelia were detected in the tissues of heart, spleen, kidney, urinary bladder and knee joint within 7 days after inoculation of infection by dark field microscopic examination. The isolation rate from heart, urinary bladder and joint was significantly higher than the rate from spleen, kidney, and blood samples. 2) The Borrelia was detected in heart muscle by indirect immunofluorescent antibody test. 3) Antibody to the Borrelia was detected as early as one week after inoculation. 4) The marked tropism of the Borrelia was observed in myocardial, urinary tract and joint tissue. The main pathological features are inflammation in tissues of heart, kidney, joint and urinary bladder. From these results, the Borrelia afzelii strain isolated in Korea were determined as pathogenic strain.

  • In order to evaluate the effect of Chekambohyulansin-tang (CST) which was a traditional poly-herbal formula has been used for treatment of obesity in Korea, on the obesity in ovariectomized rats, the changes of body weight, peri-kidney, abdominal and perineal subcutaneous fat weight and their histological changes were measured with the detection of number and/or size of adipocytes after an oral administration of CBT extracts (125, 250 and 500 mg/kg, respectively). CBT significantly attenuated elevations in the body weight, the absolute and relative weight of peri-kidney, abdominal and perineal fat tissues and decrease the severe hypertrophy, the number of adipocytes, and the diameter of adipocytes of peri-kidney, abdominal and perineal fat tissues in ovariectomized rats in a dose dependent manner. These results provide a story evidence that CBT can playa role in the treatment of obesity induced by ovariectomy. Determination of the specific mechanisms involred toxicological dosage of CBT on obesity will require addition study.

  • Background: This study aimed to investigate the effects of Oenanthe javanica (OJ) extracts on rats with potassium oxonate (PO)-induced hyperuricemia. Methods: The effects of OJ extract on rats with PO-induced hyperuricemia-induced were monitored. Changes in the body weight and organ indices of hyperuricemic rats were calculated to detect anti-hyperuricemic effects. Blood samples were collected to observe the effect of reducing serum uric acid concentration. Kidney tissues were stained to observe histopathological changes under a microscope. The activity of xanthine oxidase (XO), which catalyzes xanthine to uric acid in the liver, was assessed to observe the inhibitory effect of XO. Results: 1. The body weight of hyperuricemic rats showed no considerable differences between the control group and the treatment group. The OJ group had significantly improved liver index, whereas the allopurinol group had improved liver and kidney indices. 2. Serum uric acid levels increased significantly after PO injection, and the OJ and allopurinol groups showed a significant reduction effect. 3. PO injection led to the inflammation of kidney tissues, and OJ improved it significantly. 4. The activity of XO after PO injection was significantly increased, and allopurinol significantly inhibited XO activity in the liver. Conclusion: In the hyperuricemia rat model, OJ extract reduced uric acid concentration and demonstrated its anti-inflammatory effects. Thus, OJ extracts can be used to lower uric acid levels.
