Background: Men with chronic obstructive pulmonary disease, have reduced endogenous testosterone levels, but the relationship between pulmonary function and endogenous testosterone levels, is inconsistent. Testicular volume is a known indicator of endogenous testosterone levels, male fertility, and male potency. In the present study, the authors investigated the relationship, between testicular volume and lung function. Methods: One hundred and eighty-one South Korean men age 40–70, hospitalized for urological surgery, were retrospectively enrolled, irrespective of the presence of respiratory disease. Study subjects underwent pulmonary function testing, prior to procedures, and testicular volumes were measured by orchidometry. Testosterone levels of patients in blood samples collected between 7 AM and 11 AM, were measured by a direct chemiluminescent immunoassay. Results: The 181 study subjects were divided into two groups, by testicular volume (≥35 mL vs. <35 mL), the larger testes group, had better lung functions (forced vital capacity [FVC]: 3.87±0.65 L vs. 3.66±0.65 L, p=0.037; forced expiratory volume in 1 second [FEV1]: 2.92±0.57 L vs. 2.65±0.61 L, p=0.002; FVC % predicted: 98.2±15.2% vs. 93.8±13.1%, p=0.040; FEV1 % predicted: 105.4±19.5% vs. 95.9±21.2%, p=0.002). In addition, the proportion of patients with a FEV1/FVC of <70%, was lower in the larger testes group. Univariate analysis conducted using linear regression models, revealed that testicular volume was correlated with FVC (r=0.162, p=0.029), FEV1 (r=0.218, p=0.003), FEV1/FVC (r=0.149, p=0.046), and FEV1 % predicted (r=0.178, p=0.017), and multivariate analysis using linear regression models, revealed that testicular volume was a significant predictive factor for FEV1 % predicted (β =0.159, p=0.041). Conclusion: Larger testicular volume was independently associated, with favorable indices of lung function. These results suggest that androgens, may contribute to better lung function.

The purpose of this study was to evaluate the effects of periodontal curet and various rotating instruments on the root surfaces. Thirty-five extracted teeth with advanced periodontal disease were used. They was root planed with periodontal curet, periodontal Perio-Clean bur, periodontal Roto-Perio bur, resin polishing ET bur, and resin polishing diamond fissure bur. To find dentinal tubule orifices on the root surface, tetracycline HCI solution was applied to the one tooth of treated each group. Then, root surfaces were investigated using scanning electron microscope. Amount of loss of cementum was evaluated by loss of tooth substance index. The results were as follows. 1. Groups treated with periodontal curet and Perio-Clean bur showed irregular surface and concavities. Concavities seemed to be lacunae of cementocyte. Other groups treated with Roto-Perio bur, resin polishing ET bur, and resin polishing diamond fissure bur showed partially opened dentinal tubule orifice. 2. Groups treated with periodontal curet and Perio-Clean bur and tetracycline HCl showed irregular surface. No dentinal tubule orifice was seen. Other groups treated with Roto-Perio bur, resin polishing ET bur, and resin polishing diamond fissure bur and tetracycline HCl showed dentinal tubule orifice with various shape and size. 3. Loss of tooth substance indices were compared between groups. There was no statistically difference between periodontal curet and Perio-Clean bur groups. There were statistically differences between periodontal curet and Roto-Perio bur, ET bur, and diamond fissure bur groups. As a result of this study, groups treated with Roto-Perio bur, resin polishing ET bur, and resin polishing diamond fissure bur showed more cementum removed than groups treated with periodontal curet and Perio-Clean bur. Therefore, in a conventional treatment for periodontal disease, it was recommended that periodontal curet or Perio-Clean bur should be used. In a treatment for regeneration of periodontal tissue, it was recommended that Roto-Perio bur, resin polishing ET bur, or resin polishing diamond fissure bur should be used

Purpose: The improvement of testicular volume, testosterone levels and sperm concentration was suggested to be significantly associated with the number of internal spermatic veins (ISVs) ligated during varicocelectomy. Herein, we investigated preoperative color Doppler ultrasonography (CDU) findings as potential preoperative predictors of the number of ISVs requiring ligation during microsurgical subinguinal varicocelectomy. Materials and Methods: In a prospective evaluation of 40 patients, maximal vein size and maximal reflux velocity were measured,while the total cross-sectional area of the affected testicular veins during a Valsalva maneuver was calculated using CDU by a single uroradiologist. Microsurgical subinguinal varicocelectomies were performed by one urologist. Results: Among the semen parameters, semen morphology showed significant improvement (p=0.033), which was much clearer in the patients with a higher number of ISVs ligated than a lower number of ISVs ligated. Among the various preoperative variables, maximal reflux velocity and total cross-sectional area on CDU were related to the number of ISVs ligated (r=-0.442, p=0.004; r=0.594, p=0.000, respectively). Furthermore, univariate and multivariate linear regression analyses showed that maximal reflux velocity and total cross-sectional area on CDU were independent predictive factors of the number of ISVs ligated. Conclusion: Maximal reflux velocity and total cross-sectional area on CDU were related to the number of ISVs ligated. This means that the maximal reflux velocity and total cross-sectional area measured by preoperative CDU can predict the number of ISVs requiring ligation during microsurgical subinguinal varicocelectomy, which might be related to significant improvement of semen parameters after varicocelectomy.
