Three cases of spondyIolysis were experienced and treated by anterior interbody fusion of the involved spines at the department of orthopaedic surgery in the Taegu Hospital One case was accompanied with severe lumbago with radiating pain and other two cases with lumbago significantly. Review of literature was done with report of three cases of spondylolysis.

Emphysematous pyelonephritis is a necrotizing renal infections characterized by intrarenal and occasional perirenal gas production. Although uncommon (89 cases in the literature), it occurs almost exclusively in diabetic patients (87% of the cases). Prompt and aggressive management is required to sahage these patients. We describe a recent case of a diabetic woman with emphysematous pyelonephritis due to E. Coll, successfully managed with unilateral nephrectomy.

4.The Effect of Stress on Bladder Stability.
Korean Journal of Urology 2007;48(11):1131-1138
PURPOSE: This study was designed to examine the effect of stress on the pathophysiology of bladder stability via the Rho-kinase and nitric oxide synthase activity, which are required for muscle contraction and relaxation within the bladder. MATERIALS AND METHODS: Animal testing was conducted in two separate sessions. In the first experiment, 36 female Sprague-Dawley rats weighing about 230-270g each were employed. 18 rats were placed in the control group and 18 rats were placed in the test group. The second testing was conducted using metabolic cages. Six rats were placed in the control group and six rats were placed in the test group under a stressful environment. RESULTS: The results showed that the frequency of urination was significantly increased with time in the test group(p<0.05). However, the volume of voided urine decreased, thereby suggesting stress was a cause of overactive bladder. Analysis of bladder tissue for nitric oxide synthase (NOS) and RhoA-binding kinase(ROKalpha), important components of contraction and relaxation of bladder muscle, revealed that the levels of iNOS and ROKalpha were significantly increased with continued application of stress. This suggests that stress affects the levels of NOS and ROKalpha in an overactive bladder to influence contraction and relaxation of the bladder muscle. CONCLUSIONS: An increase in the ROKalpha expression and changes of the NOS expressions in the rats with chronic stress pathophysiologicaly support that stress contributes to the clinical symptoms of overactive bladder.

6.Change in Expression of Rho-kinase and Nitric Oxide Synthase in Penile Tissue of Rats Under Stress.
Korean Journal of Andrology 2008;26(3):130-135
PURPOSE: The autonomic nervous system (ANS) and stress hormones are important mediators in the stress response. The ANS controls the tone of corpus cavernosal smooth muscle. Clinically, it is not uncommon to develop erectile dysfunction as the sequelae of acute or chronic stress, with or without loss of libido. In this study, we investigated the effect of stress on the expression of mediators of penile corpus cavernosal smooth muscle relaxation and contraction. MATERIALS AND METHODS: Forty-eight male Sprague-Dawley rats were used, with 8 rats in each group. They were divided into six groups; stress+10, stress+20, and stress+30, which were named after their duration (days) of exposure, and a control group for each stress group. The stress group was maintained under a scheduled stress condition, while the control group was provided a comfortable general environment. Penile tissues were sampled and expressions of Rho-kinase, inducible nitric oxide synthase (iNOS), endothelial NOS (eNOS) and neuronal NOS (nNOS) were measured and analyzed by Western blotting. RESULTS: Penile Rho-kinase expression was significantly increased in the stress groups compared with the control group (p<0.05), with a greater increase during longer stress. Expression of iNOS was increased in stress+30 group (p<0.05). Expression of eNOS, nNOS, and Rho-kinase were increased in stress+20, stress+30 group (p<0.05). CONCLUSIONS: These results suggest that stress may alter penile corpus cavernosal smooth muscle relaxation by affecting mediators.

The authors obtained the following results through comparative investigation between experiences from authors clinical study of ureterolithotomy by posterior vertical incision devised by Gil-Vernet and Yoon`s clinical study of ureterolithotomy by posterior vertical incision and his lumbar incision. 1. Operation time was average 62 min. and blood loss was average about 50cc. So operation time and blood loss were similar to Yoon`s result but more or less reduced as compared with lumbar incision. 2. Postoperative urine leakage and ambulation time were 1 day and 2 day that were more or less reduced as compared with Yoon`s result. 3. Ipsilateral lower abdominal wall protrusion was noted postoperatively. We think, this is from subcostal nerve injury. 4. Postoperatively sensation change on subcostal nerve, ilohypogastric nerve and ilioinguinal nerve innervation sites were noted in half of all, but disappeared in several weeks. Considering above results, while posterior vertical incision has merits such as minimal operative invasion and early postoperative ambulation time, but it often notes inevitable nerve damage. So, we think better results would be gained by careful attention to nerve and vascular distribution.

Reversible splenial lesion syndrome can be caused by viral infection. Rubella generally occurs in
childhood, and it is rarely accompanied by neurological complications in adulthood. A 35-year-old man
visited our hospital due to conjunctival injection, mild fever, and headache 3 days after experiencing
skin rash. Brain magnetic resonance imaging (MRI) revealed distinct lesions involving white matter in
the splenium of the corpus callosum approximately 3 days following the onset of symptoms. Enzyme
immunoassay performed on serum and CSF samples was positive for rubella virus IgM. A follow-up
brain MRI was performed 24 days after the onset of symptoms, and reduced lesion size with decreased
signals were observed on diffusion weighted image. This case showed that rubella infection can result
in reversible splenial lesion accompanied by only mild neurological symptoms.

The authors report two cases of successful reconstruction in infected nonunion of the femur involving marked shortening by compression and gradual distraction at the nonunion site using Ilizarov external fixator. At first, infection was controlled by radical excision & the administration of systemic antibiotics for four weeks and we also started compression at the nonunion site 3 days after operation. Autogenous iliac bone graft was added to strengthen the site of new bone formation lastly. In this report, the role of the compression seems to provide a good environment for distraction osteogenesis by focal necrosis and triggering inflammation. Compression and gradual distraction may be one of the treatment mordalities for nonunion of a long bone with massive bone loss or shortening, even infected.
