Isometric tension was recorded in uterine arterial ring preparation contracted by potassium (60 mM) and norepinephrine(1.8 X 10(-7) M). With pretreatment of various concentrations of nifedipine(2.9 x 10(-9) ~2.9 X10(-7) M) and verapamil(2.2 X 10(-7) -2.2 X 10(-5) M), the relaxation was dose-dependent and inhibitory effects of both agents were more marked on the potassium than norepinephrine-evoked contraction. After immersion of the arterial preparation in calcium-free solution, the potassium-evoked contraction was decreased to 21+/-4.1%(mean+/-SEM) of the response in normal Krebs solution and norepinephrine-evoked contraction to 26+/-3.8%. The responses to both agents were completely restored when the calcium concentration was increased to 4.0 mM. Pretreated nifedipine(2.9 x 10(-7) M) in calcium-free solution depressed the potassium-evoked contraction to 7.3+/-1.6% and norepinephrine-evoked contraction to 12+/-3.7%. In addition of calcium(0-4.0mM), the potassium-evoked contraction increased to 30+/-4.6% and that by norepinephrine to 45+/-5.4%. Pretreated verapamil(2.2 X 10(-5) M) in calcium-free solution depressed the potassium-evoked contraction to 14+/-3.6% and norepinephrine-evoked contraction to 18+/-3.3%. In addition of calcium(0-4.0mM), the potassium-evoked contraction increased to 41+/-4.2% and that by norepinephrine to 57+/-4.7%. It was concluded that nifedipine and verapamil relaxed KC1 contracted ring in the presence of external calcium and relaxed norepinephrine contracted ring in both the presence and absence of external calcium. These findings suggest that calcium antagonists interfere with the release of calcium from intracellular sites as well as with the slow inward current of calcium.

Renal cell carcinoma takes up 85 per cent of primary malignant renal tumors. It frequently metastasizes to the adrenal gland, lung, bone, liver and nephrectomy site but rarely to the head and neck area. When metastasizes to head and neck area, it involves the gingiva, tongue, palate, parotid gland, uvula, mandible, and lip. When tumors are found in the salivary gland consisting of clear cells, it is impartant to carry out differential diagnosis of various primary tumors with clear cell and metastatic renal cell carcinoma. Patients' medical history, review of system, and pathologic findings would be helpful factors in the differential diagnosis. In this paper, we report on a case of renal cell carcinoma which had metastasized to the psubmandibular gland after a radical nephrectomy.

OBJECTIVES: Radioiodine (RI) therapy is known to subject cellular components of salivary glands (SG) to oxidative stress leading to SG dysfunction. However, the protective effects of antioxidants on RI-induced SG damage have not been well investigated. The authors investigated the morphometric and functional effects of epigallocatechin-3-gallate (EGCG) administered prior to RI therapy and compared this with the effects of amifostine (a well-known antioxidant) in a murine model of RI sialadenitis. METHODS: Four-week-old female C57BL/6 mice (n=48) were divided into four groups; a normal control group, a RI-treated group (0.01 mCi/g mouse, orally), an EGCG and RI-treated group, and an amifostine and RI-treated group. Animals in these groups were divided into 3 subgroups and euthanized at 15, 30, and 90 days post-RI treatment. Salivary flow rates and lag times were measured, and morphologic and histologic examinations and TUNEL (terminal deoxynucleotidyl transferase biotin-dUDP nick end labeling) assays were performed. Changes in salivary (99m)Tc pertechnetate uptake and excretion were followed by single-photon emission computed tomography. RESULTS: Salivary flow rates and lag times to salivation in the EGCG or amifostine groups were better than in the RI-treated group. Histologic examinations of SGs in the EGCG or amifostine group showed more mucin-rich parenchyma and less periductal fibrosis than in the RI-treated group. Fewer apoptotic cells were observed in acini, ducts, and among endothelial cells in the EGCG or amifostine group than in the RI group. In addition, patterns of (99m)Tc pertechnetate excretion were quite different in the EGCG or amifostine group than in the RI group. CONCLUSION: EGCG supplementation before RI therapy could protect from RI-induced SG damage in a manner comparable to amifostine, and thus, offers a possible means of preventing SG damage by RI.

Myotonic dystrophy is the most common autosomal dominant myopathy in adults. Our patient, a 41 year-old female suffering from myotonic muscular dystrophy, developed upper thoracic myelopathy due to hypertrophy of the ligamentum flavum and the posterior longitudinal ligament. She had a typical hatchet face and ptosis with "head hanging forward" appearance caused by neck weakness. Motor weakness, sensory changes and severe pain below T4 level, along with urinary incontinence began 3 months ago. Genetic and electrodiagnostic studies revealed myotonic dystrophy type 1. Magnetic resonance imaging of the spine showed loss of cervical lordosis and spinal cord compression due to hypertrophied ligamentum flavum and posterior longitudinal ligament at T1 to T3 level. We concluded that her upper thoracic myelopathy was likely related to the thickness of the ligamentum flavum and posterior longitudinal ligament due to repetitive mechanical stress on her neck caused by neck muscle weakness with myotonic dystrophy.

OBJECTIVE: To evaluate the association between the severity of endometriosis and the preoperative neutrophil-to-lymphocyte ratio (NLR) and serum level of cancer antigen 125 (CA 125). METHODS: Data were obtained from the medical records of 419 patients who underwent laparoscopic conservative surgery for ovarian endometrioma between April 2005 and March 2013. Each patient's preoperative complete blood count was recorded and the endometriosis score was assessed. RESULTS: The endometriosis score was not associated with either the NLR or the serum level of CA 125. The endometriosis score was negatively related to preoperative hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration. The only positive association was between NLR and the patients' age. NLR and preoperative serum anti-Mullerian hormone level were found to be negatively related. CONCLUSION: The severity of endometriosis was not associated with the serum level of CA 125 or the NLR. The presence of a negative correlation between the severity of endometriosis and red blood cell dynamics needs further investigation.

OBJECTIVE: To identify differences in the expression of the genes for peroxisome proliferator-activated receptor (PPAR)-γ, cyclooxygenase (COX)-2, and the proinflammatory cytokines interleukin (IL)-6 and tumor necrosis factor (TNF)-α in granulosa cells (GCs) from polycystic ovary syndrome (PCOS) patients and controls undergoing controlled ovarian stimulation. METHODS: Nine patients with PCOS and six controls were enrolled in this study. On the day of oocyte retrieval, GCs were collected from pooled follicular fluid. Total mRNA was extracted from GCs. Reverse transcription was performed and gene expression levels were quantified by realtime quantitative polymerase chain reaction. RESULTS: There were no significant differences in age, body mass index, and total gonadotropin dose, except for the ratio of luteinizing hormone to follicle-stimulating hormone between the PCOS and control groups. PPAR-γ and COX-2 mRNA was significantly downregulated in the GCs of PCOS women compared with controls (p=0.034 and p=0.018, respectively), but the expression of IL-6 and TNF-α mRNA did not show significant differences. No significant correlation was detected between the expression of these mRNA sequences and clinical characteristics, including the number of retrieved oocytes, oocyte maturity, cleavage, or the good embryo rate. Positive correlations were found among the PPAR-γ, COX-2, IL-6, and TNF-α mRNA levels. CONCLUSION: Our data may provide novel clues regarding ovarian GC dysfunction in PCOS, and indirectly provide evidence that the effect of PPAR-γ agonists in PCOS might result from alterations in the ovarian follicular environment. Further studies with a larger sample size are required to confirm these proposals.

We report two cases of cutaneous Mycobacterium(M.) marinum infections in a 43-year-old man and a 31-year-old woman who had multiple subcutaneous nodules on the left upper extremity and an erythematous ulcer on the right elbow, respectively. Skin biopsy specimens revealed chronic granulamatous inflammation and AFB positive bacilli in the dermis. The culture from tissue specimens on Lowenstein-Jensen media at 30'C for 10 days, yielded cream-colored colonies, which became yellow when exposed to light. The organism was identified as M. marinum by selected biochemical reactions. The patients were treated with surgical excision followed by administration of minocycline and administration of minocycline, respectively.

Xanthogranulomatous pyelonephritis is a chronic inflammatory condition that can only be diagnosed by histological examination, and is often associated with renal calculi, obstruction and urinary tract infection. We report a case of bilateral xanthogranulomatous pyelonephritis in a child with end stage renal disease, which was misdiagnosed as renal cell carcinoma preoperatively.

PURPOSE: N-acetylcysteine (NAC) has been known to have protective effects on the prevention of radiocontrast induced nephropathy (RCIN) in chronic renal failure (CRF). We investigated the effects of NAC in acute renal failure (ARF). METHODS: From January to June 2006, we retrospectively enrolled patients with ARF who were checked with contrast computed tomography (CT) at an emergency department. We divided patients into the NAC group and the control group. We compared baseline demographic characteristics, underlying diseases, infused fluid volume, blood urea nitrogen (BUN), and serum creatinine (Cr) level before and after CT scan. ARF was defined as serum Cr>1.5. mg/dL. RCIN was defined as an increase in serum Cr level of at least 0.5 mg/dL or 25% 48 hours after CT. RESULTS: Of a total 106 cases, 23 patients were the NAC group and 83 were the control group. There were no significant differences in baseline findings including underlying disease, cause of ARF and serum Cr level. The volume of infused fluid before and after CT were not different between the two groups (before; p=0.183 after; p=0.149). After CT scan, BUN and serum Cr level were decreased without statistical significance in both groups (NAC vs control group: BUN; 21.0+/-12.9 vs 20.5+/-14.2 p=0.863 Cr; 1.3+/-0.5 vs 1.4+/-0.5 p=0.451). RCIN developed in total 3 cases, 2 cases in the NAC group and 1 in the control group (p=0.524) and one of the NAC group performed hemodialysis. CONCLUSION: In case of patients with ARF, there was no protective effect of NAC on RCIN.
