  • To identify the treatment effect of lactic acid bacteria for diabetes, the treatment effects of a single administration of acarbose (a diabetes treatment drug) or lactic acid bacteria, and the mixture of acarbose and lactic acid bacteria on diabetes in a type 1 diabetes animal model, were studied. In this study, streptozotocin was inoculated into a Sprague-Dawley rat to induce diabetes, and sham control (Sham), diabetic control (STZ), STZ and composition with live cell, STZ and composition with heat killed cell, STZ and composition with drugs (acarbose) were orally administered. Then the treatment effect on diabetes was observed by measuring the body weight, blood glucose, and serum lipid. For the histopathological examination of the pancreas, the Langerhans islet of the pancreas was observed using hematoxylin and eosin staining, and the renal cortex, outer medullar, and inner medullar were also observed. The induced diabetes decreased the body weight, and the fasting blood glucose level decreased in the lactic-acid-bacteria-administered group and the mixture-administered group. In addition, the probiotic resulted in the greatest decrease in the serum cholesterol level, which is closely related to diabetes. Also, the hematoxylin and eosin staining of the Langerhans islet showed that the reduction in the size of the Langerhans islet slowed in the lactic-acid-bacteria-administered group. The histopathological examination confirmed that the symptoms of diabetic nephropathy decreased in the group to which viable bacteria and acarbose were administered, unlike in the group to which dead bacteria was administered. The mixture of lactic acid bacteria and acarbose and the single administration of lactic acid bacteria or acarbose had treatment effects on the size of the Langerhans islet and of the kidney histopathology. Thus, it is believed that lactic acid bacteria have treatment effects on diabetes and can be used as supplements for the treatment of diabetes.

  • Objectives: We designed the study to compare the oncologic and renal function outcomes of off-clamp, laparoscopic partial nephrectomy (OCLPN) and conventional laparoscopic partial nephrectomy (HCLPN) for renal tumors. Methods: Between March 2008 and July 2015, 114 patients who underwent laparoscopic partial nephrectomy (LPN) of a renal neoplasm were studied. We performed LPN without hilar clamp on 40 patients (OCLPN, Group 1), and conventional LPN with hilar control and renorrhaphy on another 40 patients (HCLPN, Group 2). We retrospectively reviewed the medical records of each patient's age, sex, R.E.N.A.L. nephrometry score (RNS), operation time, complications, hospitalization period, tumor size, positive resection margin, histologic classification of tumor, pathologic stage, Fuhrman grade, estimated blood loss (EBL), warm ischemic time (WIT), and estimated glomerular filtration rate (eGFR) before and one year after surgery. Results: There were no significant differences in age, sex, preoperative eGFR, EBL, surgical (anesthesia) time, and tumor size between the two groups. The mean eGFR was not significantly different between the OCLPN and HCLPN groups 1 month (95 and $86.2mL/min/1.73m^2$, respectively; P = 0.106), 6 months (92.9 and $83.6mL/min/1.73m^2$, respectively; P = 0.151) and 12 months (93.8 and $84.7mL/min/1.73m^2$, respectively; P = 0.077) postoperatively. The change in eGFR after one year was 3.9% in the OCLPN group and -7.9% in the HCLPN group. Conclusions: OCLPN was superior to HCLPN in preserving renal function one year after surgery, and there was no statistically significant difference in tumor treatment results.

  • The present study is designed that the herb medicines which are returned to kidney, pancreas and are known by efficacy in growth are supplied to pigs, thereafter the effects to growth and secretion of growth hormone in serum is investigated. For this purpose the 24 days old pigs, which are crossbreeding, castrated are used. The conclusions are that after 4 weeks' supply of herb medicinal compounds, pigs' weight gain has increased in low nutritional group with statistical meaning(p〈0.05). And one day's weight gain has increased with statistical meaning(p〈0.05) in all groups. Regarding food take, the second nutritional group has more significant increase than control group. Utilization rate of nutrition doesn't have any statistical meaning in all groups, but it has the tendency that as herb medicinal compounds are added, utilization rate of nutrition is increased. Increase of vertebra lengths and level of growth hormone in serum according to supply of herb medicinal compound don't have any statistical meaning because of small sample size, but 10 - 20 % increase of vertebra lengths and 10 - 30 % increase of level of growth hormone are observed.

  • Malignant schwannoma is rare tumor which is derived from schwas cells or nerve sheath cells, and it is frequently associated with Von Rechlinghausen's disease. We experienced one case of malignant schwannoma on the right chest wall without Von Rechlinghausen's disease. Patient was 64-year-old man who presented painless palpable mass on the right lower -chest wall for about 2 months. On chest computed tomography, the mass which was 6$\times$6 cm in size and had central necrosis, involved 11th rib with destruction, invaded the diaphragm and displaced the kidney anteriorlly. He underwent on-bloc resection of the tumor and discharged without any problem after 20 days.

  • Sprague-Dawley rats received subcutaneous injections of gentamicin sulfate, 50 and 100mg/kg for 3, 7 and 10 days. The hematological and blood chemical values were determined. Kidneys were examined histologically and ultrastructurally. The results obtained were summarized as follows; 1. The serum values of aspartate transaminase, blood urea nitrogen and creatinine in the rats administered gentamicin, 50 and 100mg/kg/day were significantly increased than those in the control. 2. The ratio of kidney weight to body weight was significantly increased in the rats injected gentamicin, 100mg/kg for 10 days than those in the control. 3. The brush borders of proximal convoluted tubules in the kindneys received gentamicin, 50 and 100mg/kg/day were decreased or absent in periodic acid-Schiff staining. 4. The necrosis of proximal convoluted tubules was shown in the rats given gentamicin, 50 and 100mg/kg for 7 and 10 days. 5. The regeneration of the proximal tubular epithelia was observed in the rats treated gentamicin, 100mg/kg for 10 days. 6. The number and size of lysosomes were increased in the proximal convoluted tubules of the rats injected gentamicin, 50mg/kg for 7 days, many of which contained myeloid bodies.

  • Purpose: : To assess the clinic value of application of laparospic ultrasonography (LU) in partial nephrectomy of small renal cell carcinoma. Materials and Methods: From 2007 to 2011, 28 small renal cell carcinoma patients in ou clinic underwent laparoscopic partial nephrectomy with LU. For comparison with preoperative conventional ultrasound and CT, we collected ultrasonic performance of the affected side kidney, renal tumor location, size, echo change, blood supply situation and the relationship with the surrounding tissue. Results: LU could more clearly show the tumor interior structure and blood supply, as well as the relationship with the surrounding tissue. It also can provided doctor assistance with real-time tumor resection, reducing operative complications. Conclusions: LU can clearly show tumor internal structure and blood supply, which is helpful for explicit diagnosis. Moreover, it supplies accurate information for surgeons and assists surgery. Therefore LU has an important guiding value in partial nephrectomy for small renal cell carcinoma.

  • Biological samples can be fixed either by chemical method by using chemical solution or physical methods by using heat treatment. The problem in traditional heat fixation is unsatisfactory quality due to uneven heat conduction in specimen and loss of inner cell contents. Chemical fixation method also bears several intrinsic problems like the limit in specimen size, time consumption in fixative impregnation, and loss of low molecular weight cell components. These factors deteriorate the quality of fixed specimen, thus limit the magnification and contrast of tissue pictures. Microwave heat has been reported to be a good alternative to current chemical methods to overcome these problem. In this study, we tried to introduce the microwave energy method to routine fixation work in hospital. We replaced chemical fixative with saline to provide moderate reaction condition, and used frozen section to reduce time for sample preparation. Temperature was measured at each experiment. The fixation of rat kidney tissue with 2.45 GHz electromagnetic wave and saline showed similar result to the control group fixed with traditional chemical method. Human tumor tissue fixed with 2.45 GHz electromagnetic in frozen section was improved in terms of histochemistry of PAS and immunohistochemistry of tumor marker like cytokeratin. Total turnaround time was reduced from $24\sim38$ h to to $2\sim4$ h. In conclusion, the quality of samples prepared by microwave heating method was at least as good as that of traditional method. If the condition for the fixation of different specimens is standardized, this new method could be applied to routine work in hospital, and could save working time as well.

  • Serial ultrasonographic examinations were daily performed on 12 Shih-tzu bitches from 15 days after ovulation until parturition to determine the time of first detection and ultrasonographic appearance of the fetal and extra-fetal structures and to determine the size of gestational structures. Gestational age was timed from the day of ovulation (day 0), which was estimated to occur when plasma progesterone concentration was first increased above 4.0 ng/ml. The gestational length in 12 Shih-tzu bitches was 62.1 (range:60-64) days. The initial detection of the fetal and extra-fetal structures were: gestational sac at days 19.2 (16-21); zonary placenta in the uterine wall at days 25.9 (24-28); yolk sac membrane at days 24.1 (22-26); amniotic membrane at days 26.6 (24-28); embryo initial detection at days 22.3 (21-24); heartbeat at days 23.8 (23-25); limb buds at days 29.3 (27-31); fetal movement at days 32.3 (31-34); stomach at days 32.6 (29-34); urinary bladder at days 33.1 (29-35); skeleton at days 35.9 (34-38) and kidney at days 45.8 (45-48).

  • Using morphometric technique, the present study was made of the kidney of rabbit embryo in the 13 days of the gestation. Their section areas of the renal tubules and the glomerular cells were compared with the those of adult rabbit, 1. In the developing renal tubule, the tubular section areas were larger than that of the adult, but the nuclear section areas of tubular calls were smaller than the adult. The microvilli of their cell surface were poorly developed, and their cytoplasm contained well developed mitochondria with euchromatic nucleus. 2. In the developing glomeruli. the nuclear section area of the cells of the parietal layer, the podocytes, and the endothelial cells were similar size, but their nuclei were larger than those of the adult. The cytopalsm of the podocytes contained well-developed rough endoplasmic reticulum, Golgi apparatus, and round mitochondria.
