Boar Quality Semen Testing and Presence of Mycoplasma Organism

This paper describes results of mycoplasma organism and Mycoplasma hyopneumoniae detection in semen of boars. During routine examination of semen quality in 2015 and 2016, different percent of specific changes in the spermatozoa of 23 b oars were observed and these samples were subjected to mycoplasma detection. The se changes were manifested as frequent distal midpiece reflex abnormalities with sporadic coiled principal piece; but booth loops were filed with fine, net like /reticular form s ( “ entrapped pseudocytoplasmatic droplet ” ). Based on the observed morphological forms i t is suspected on the presence and influence of microorganisms, primarily of Mycoplasma origin . PCR and real time PCR molecular methods were examined in all suspected s perm samples. The presence of Mycoplasma spp was found in 15 samples, of which, Mycoplasma hyopneumoniae was found in 8 samples. In the remaining seven samples differentiation to other mycoplasma species were not carried out . This article is indicating t hat genital form of mycoplasma could manifest its effect on semen quality and this may be more significant than current literature data are indicating and recogniz ing as problem in boars. In the same time, i ts high incidence in suspected semen samples coul d be more stressed as a source of sexually transmitted infection. Further estimation of Mycoplasma influence on boar semen quality is needed.

Serum and Saliva MMP-3 in Patients with OLP and Oral SCC

ABSTRACT Background Matrix metalloproteinase-3 (MMP-3) plays a key role in development of cancer. The purpose of this study was to assess MMP-3 in the serum and saliva of patients with oral lichen planus (OLP) and oral squamous cell carcinoma (OSCC). Materials and methods Thirty patients with OLP (8 reticular and 22 erosive forms), and 20 patients with OSCC (6 in low stage and 14 in advanced stage), were enrolled in this study, conducted at the Cancer Department, Clinic of Oral Medicine, Tehran University of Medical Sciences. The serum and saliva MMP-3 was assayed by ELISA method. Statistical analysis of the Student's t-test, ANOVA and Pearson correlation coefficient was performed. The mean saliva and serum levels of MMP-3 were significantly higher in patients with OSCC compared with OLP. Results The serum and saliva MMP-3 concentrations increased from reticular form of OLP to erosive form of OLP, and increased further to low stage of OSCC and advanced stage of OSCC. Serum MMP-3 correlated significantly with unstimulated (r = 0.310, p = 0.038) and stimulated (r = 0.365, p < 0.026) saliva MMP-3. Conclusion Serum and saliva MMP-3 levels appear associated with OLP and OSCC. How to cite this article Agha-Hosseini F, Mirzaii-Dizgah I, Mahboobi N, Shirazian S, Harirchi I.

Gyvenimo kokybė sergant erozineopine ir retikuline plokščiosios kerpligės formomis

The present work analyses various life quality aspects of 79 patients with oral lichen planus, who were examined in the Žalgiris Clinic of Vilnius University Hospital in the period 2009-2012. Oral lichen planus had different forms of the disease and individual experience, which impacted quality of life. The erosive-ulcerative form of the disease as compared to reticular form had more detrimental influence on psychological, social or physical comfort of patients. A high percentage of patients (48,3% erosive-ulcerative form and 44,5% reticular form) were concerned about their future with oral lichen planus.

Oral Lichen Planus : A Review

Oral lichen planus (OLP) is a chronic mucosal condition commonly encountered in clinical dental practice. Lichen planus is believed to represent an abnormal immune response in which epithelial cells are recognized as foreign, secondary to changes in the antigenicity of the cell surface. It has various oral manifestations, the reticular form being the most common. The erosive and atrophic forms of OLP are less common, yet are most likely to cause symptoms. Topical corticosteroids constitute the mainstay of treatment for symptomatic lesions of OLP. Recalcitrant lesions can be treated with systemic steroids or other systemic medications. However, there is only weak evidence that these treatments are superior to placebo. Given reports of a slightly greater risk of squamous cell carcinoma developing in areas of erosive OLP, it is important for clinicians to maintain a high index of suspicion for all intraoral lichenoid lesions. Periodic follow-up of all patients with OLP is recommended.
