Background: This study investigates the levels of superoxide dismutase (SOD) activity in serum and saliva of patients with chronic periodontitis (CP). In addition, the outcome of scaling and root planing (SRP) with and without vitamin E supplementation is evaluated in terms of changes in periodontal parameters and SOD activity in patients with CP. Methods: Serum and salivary SOD activity in 38 patients with CP were compared with those of 22 systemically and periodontally healthy individuals (control group). At periodontal examination, serum and saliva samples were obtained. Patients with CP were randomly divided into treatment groups 1 (TG‐1) and 2 (TG‐2). SRP was performed for both groups, and TG‐2 also received 200 mg (300 IU) vitamin E every other day. Periodontal parameters and SOD activity were evaluated after 3 months. SOD activity was determined using an SOD assay and enzyme‐linked immunosorbent assay reader at 450 nm. Results: SOD activity in both serum (P <0.05) and saliva (P <0.001) was lower in patients with CP compared with controls. After 3 months of follow‐up, SOD activity improved in both treatment groups; however, the improvement in TG‐2 was higher than in TG‐1, along with more improvement in periodontal parameters. Serum SOD levels in TG‐2 increased even above the level of the control group. Conclusions: Systemic and local SOD levels are lowered in CP. Adjunctive vitamin E supplementation improves periodontal healing as well as antioxidant defense. 相似文献

Background: Recently, some studies have revealed the effect of polycystic ovary syndrome (PCOS) on gingival inflammation. This cross‐sectional study attempts to assess the periodontal status and systemic inflammation of women receiving medical treatment for PCOS and women newly diagnosed with PCOS. Methods: A total of 126 participants comprising 41 newly diagnosed patients with PCOS (PCOS‐N), 45 patients with PCOS on medical treatment (PCOS‐MT), and 40 systemically healthy controls (control group [CG]) were examined. Periodontal parameters, anthropometric parameters, and serum levels of high‐sensitivity C‐reactive protein (hsCRP) were recorded. Results: Women with newly diagnosed PCOS had increased sites with bleeding on probing (BOP), probing depth, clinical attachment level (CAL), waist circumference (WC), hsCRP, and prevalence of periodontitis compared with control and PCOS‐MT groups (P ≤0.05). On partial correlation analysis after controlling for confounders, BOP and CAL correlated positively and significantly with hsCRP (P = 0.01 and P = 0.005). Multivariate linear regression analysis revealed that BOP and CAL (dependent variable) (P = 0.009/R2 = 0.05 and P = 0.005/R2 = 0.07, respectively) had significant association with hsCRP. Furthermore, hsCRP, when considered as outcome, also exhibited association with CAL and WC (P = 0.002/R2 = 0.07 and P = 0.04/R2 = 0.106). Logistic regression analysis demonstrated that the PCOS‐N group had 2.88 times increased likelihood of having moderate periodontitis (adjusted odds ratio 2.88, 95% confidence interval 1.18 to 6.98). Conclusions: Women with newly diagnosed PCOS may have increased prevalence and likelihood for periodontitis, with higher measures of periodontal inflammation and breakdown than those on medical treatment for PCOS and systemically healthy females. Furthermore, periodontal breakdown might depend on systemic inflammation and vice versa. 相似文献

Objectives
Study includes 20 patients with diagnosis of fascial space infections of odontogenic origin to assess efficacy of serum prealbumin and CRP levels as monitoring tools for determining severity of infections, nutritional status, hospital stay and efficacy of treatment.Methods
Blood samples taken on day 0, 4, and 8 for measuring serum levels of markers. Simultaneously clinical parameters like swelling size, pain etc., were also recorded on day 0, 4, and 8 and appropriate treatment given to each patient. Correlation between markers and parameters was found using regression and paired t test.Results
Statistical analysis found strong correlation between laboratory values of markers and parameters used to measure severity of infection also. Prealbumin and crp are significant markers for hospital stay (p < 0.01). Prealbumin also found to be a sensitive indicator of nutritional status (p < 0.001).Interpretation and Conclusion
Prospective analysis indicates prealbumin and crp are effective markers for determining severity of infection, treatment efficacy and hospital stay. Prealbumin is also sensitive marker for nutritional status. Duration of antibiotic usage, intensive unit care, use of nutritional supplements becomes more rationale. Markers also make treatment cost effective and help protecting patients from side effects of excess drug usage. 相似文献954.

We report a case of aggressive pilomatrixoma (PMX) in a 25‐year‐old male who presented with swelling in left supraclavicular region of 2‐month duration. A diagnosis of small round cell tumor was suggested on fine‐needle aspiration cytology. He underwent wide excision of the mass. On histomorphological examination, a diagnosis of aggressive PMX was made. The swelling recurred after 3 months of complete resection and on examination had similar morphological features. The case is presented because of the potential diagnostic difficulties on cytological examination and rare occurrence of aggressive variant of PMX. Diagn.

Palpable chest wall lesions are unusual manifestation of an underlying thoracic pathology and it is difficult to diagnose them with their diverse spectrum ranging from benign to malignant. Considering the exposure of patient to invasive biopsy/excision and the risk of local complications, FNAC is now being increasingly used in the primary assessment of these lesions. Objectives of this study were to report the spectrum of chest wall lesions in the population of a developing country and evaluating the diagnostic role of FNAC. All the patients who presented with palpable cutaneous or subcutaneous chest wall swelling during a period of January 2003 to August 2010 were reviewed retrospectively. May Grunwald Giemsa and Papanicolaou stained aspirates were examined, along with special stains. Seven hundred seventy‐three cases were subjected to chest wall FNAC, of which 726 (93.9%) cases were satisfactory. Age ranged from 1 to 93 years with M:F = 0.92:1. 358 (49.3%) were diagnosed as inflammatory and 368 (50.7%) were neoplastic lesions. Two‐hundred thirty four cases (32.2%) were diagnosed as mycobacterial abscess (likely tuberculous). Of the neoplastic lesions, 153 were malignant with carcinomas being predominant (88.2%). Malignant cases comprised of scar site recurrence in breast carcinoma (73 cases), metastatic carcinomas (62 cases), primary sarcomas (eight cases), hematological neoplasms (six cases), and miscellaneous group (four cases). Overall malignant lesions accounted for 21.1% (153/726) of satisfactory chest wall aspirates. FNAC is very useful and simple investigation for early diagnosis of chest wall abscesses, cutaneous metastases from visceral malignancies, and scar site recurrence in breast carcinoma. Diagn.

The detection of Trypanosoma evansi in blood is intricate, primarily in chronic stage of infection, as the parasitaemia is often low and fluctuating. The climatic conditions of the target area of Punjab (a province of India with a total of 34,000 horses and ponies used for sports and transport) are conducive for the parasite propagation. The objective of present investigation was to assess the prevalence of T. evansi in central and western Punjab by PCR and card agglutination test (CATT/T. evansi) in relation to clinico-haematobiochemical alterations and risk factors associated with latent trypanosomosis. A total of 169 equine blood and serum samples tested by CATT/T. evansi revealed 16 cases positive, with 6.8% from central plain and 13.63% from western zone. To assess the specificity of serological test, PCR1 was performed using established primer pair TR3 5′-GCG CGG ATT CTT TGC AGA CGA-3′ and TR4 5′-TGC AGA CAC TGG AAT GTT ACT-3′ for T. evansi. PCR2 applied with primer pair RoTat1.2F: 5′-ATG TCA ACG ATG CCT GTT ACA TTA CGC AC-3′ and RoTat1.2R: 5′-TAA ATA TCA CTG TCA AGA CCT GCT GCG G-3′ to rule out the consensus between the finding of the two PCR assays and agglutination test for T. evansi, which displayed results in concordance with PCR1. PCR assays showed 1.92 and 1.51% positive samples from central plain and western zone, respectively. With respect to PCR assay, CATT/T. evansi showed 100% sensitivity and 92.1% specificity. Microscopy showed a very low prevalence rate of 0.59% with only one sample positive with teaming parasitaemia. Comparison between sexes revealed higher positivity in mares by the three tests (BSE: 0.95%, PCR: 2.88%, CATT/T. evansi: 14.42%). The haemato-biochemical factors were found to be altered in PCR positive cases, while the mean value of vital parameters lied in normal range in seropositive cases. The female horse (RR = 0.0937, 95% CI = 1.388–190.223%) population was found to be at the highest risk of seropositivity for T. evansi, particularly in the unorganized farms (RR = 19.726, 95% CI = 2.918–400.221%). 相似文献

Dietary consumption of green vegetables has been associated with protection against mutagenic and clastogenic activity of genotoxicants. Chlorophyll, being present in all green plants, had earlier been suggested to be the principal factor involved. Mice were administered (i) crude aqueous extract of leaf of Indian spinach, Beta vulgaris L. var. benghalensis Hort., and equivalent amounts of (ii) chlorophyll extracted from the leaf; (iii) purified chlorophyll, (iv) chlorophyllin, a sodium-copper derivative of chlorophyll; daily for 7 days. On day 7, one set of mice from each treatment was administered potassium dichromate—a known metallic clastogen. The mice were sacrificed after 24 hours. Chromosome preparations were made from bone marrow following the usual colchicine-air dry-Giemsa schedule. The cytogenetic endpoints scored were chromosomal aberrations and damaged cells. Crude leaf extract and chlorophyllin were nonclastogenic and reduced the clastogenic effects of potassium dichromate to the control distilled water level. Chlorophyll alone, whether extracted from the leaf or obtained in commercially purified form, was clastogenic and could reduce the effects of the chromium salt only to its own level. The protective action of the crude leaf extract may be attributed to the total effect of the interaction between the different components within the leaf extract, in which the clastogenicity of chlorophyll had been neutralized. © 1996 Wiley-Liss, Inc. 相似文献

Objective. Neuromuscular joint protection requires proprioceptive input and motor output. Impairment of proprioception in knee osteoarthritis (OA) may contribute to, and/or result from, the disease. If this impairment was exclusively a local result of OA, a between-knee difference would be expected in patients with unilateral OA (UOA). To explore causal directions, 2 hypotheses were tested: 1) proprioception is worse in UOA patients versus elderly controls; 2) proprioception is worse in the arthritic knee versus the unaffected knee in UOA patients. Methods. Twenty-eight UOA patients (Kellgren-Lawrence grade ⩾2 in 1 knee and <2 in the other knee) and 29 elderly controls were enrolled. The unaffected knee of each UOA patient and both knees of the elderly controls were required to meet symptom, examination, and radiographic criteria. Proprioception (detection threshold of joint displacement after slow, passive, automated knee motion), body mass index, pain, functional status, range of motion, and laxity were measured. Results. UOA patients had worse proprioception than did elderly controls, in either knee. A between-knee difference was not found in UOA patients. Conclusion. Impaired proprioception is not exclusively a local result of disease in knee OA. The relative importance of impaired proprioception in the development and progression of knee OA will require longitudinal study. 相似文献
