Abstract
Background and Aim: Lichen planus (LP) is a cutaneous disease characterized by violaceus flat topped papules in variable size. It may involve body surface areas such as mocus membranes. Some studies have reported an association between oral LP ad diabetes mellitus. The aim of this study was to compare the frequency of diabetes mellitus between patients with and individuals without LP.
Methods: A case-control study was done on 30 patients suffering oral LP as case group and 60 healthy individuals as control group. Diagnosis of oral LP was confirmed by typical clinical and histopathologic findings. Participants in control group were selected from general population after matching for sex and age. Venipuncture was done to take 5 ml blood sample for measuring fasting serum blood glucose levels in both groups. A repeated blood sampling was done for ones with abnormal results in the first sampling. Findings of the study were analyzed using SPSS 16.0 statistical software.
Results: Thirty LP patients [man 13 (43.3%), woman 17 (56.7%)] with mean age (mean±stabdard deviation) of 46±13.7 years and 60 healthy individuals [man 26(43.3%), woman 34 (56.7%)] with mean ages of 46±14 years were recruited to this study. In case group only one person (3.3%) suffered from diabetes mellitus, but none of healthy group had fasting blood sugar above the normal value. In quantative evaluation, mean level of fasting blood sufar was 102.5±33 mg/dL in case group and 111.1±49.3 mg/dLin control group (P=0.09).

Abstract
Background and Aim: Hirsutism is defined as male pattern hair growth in females which affects 10% of women. Our aim was to compare free salivary and free serum testosterone levels in women with hirsutism and healthy controls.
Methods: This study was a case-control study in which 30 hirsute women in child bearing age were recruited and compared with 10 healthy controls. For each patient, a questionnaire containing demographic, clinical and laboratory information was completed. The salivary and serum total and free testosterone plus free androgen index were measured by radioimmunoassay (RIA) method. The collected data were described and analyzed using SPSS software version 11.5. Significance level was determined at 0.05.
Results: No significant correlation was seen between salivary and serum free testosterone and in free androgen index with free testosteron in patients and control groups. Comparing the results between case and control groups, except for mean serum total testosterone level (P<0.05), the other results were not significantly different. No significant correlation was seen between hirsutism severity and free serum or salivary testosterone levels. Significant correlation was seen with total serum testosterone (P<0.001). Investigating correlations between these hormones with serum free androgen index, only salivary free testosterone was correlated with this index (r=0.01, P<0.05).
Conclusion: In our study, we find no correlation between free serum and salivary testosterone, so it seems that this evaluation method is not an appropriate alternative for serum evaluation of this hormone.

Abstract
Background and Aim: Pemphigus vulgaris (PV) is the most common bullous autoimmune disease, which can cause mortality and morbidity in the patients who suffer from it. Researches to find reliable noninvasive laboratory tests to diagnose and monitor PV patients are being conducted.The aim of this study is to find the sensitivity of serum and salivary anti-DSG1 and anti-DSG3 antibodies in the diagnosis of PV by ELISA and to compare the results of serum and salivary autoantibodies with each other.
Methods: In this case-control study, 40 newly diagnosed patients with PV were recruited. Forty healthy controls were also recruited to this study. The clinical diagnosis of PV was confirmed by histopathology and direct immunofluorescence (DIF). Demographic data, disease severity and phenotypes were recorded on the questionnaires, which were developed for this study. DSG1 and DSG3 ELISA test were performed on serum and salivary samples of patients and controls.
Results: The mean±standard deviation age of patients, 43.37±11.94, with a range of 26 to 71 years. The sensitivities of serum anti-DSG3 and anti-DSG1 were 85% (34 cases had positive test results) and 90%, (36 cases had positive test results) respectively. The sensitivities of salivary anti-DSG3 and anti-DSG1 antibodies were accordingly 42.5% (17 cases had positive test results) and 60%, (24 cases had positive test results) respectively.
Conclusion: While the sensitivities of serum ELISA in detection of anti-DSG1 and anti-DSG3 were significantly higher than those of salivary ELISA, since the levels of the latter are chnaging in parallel to those of serum ELISA, they might be used to monitor the disease activity.

Abstract
The aim of this study was to investigate the possibility of using saliva instead of serum (as a simpler method without the need for blood sampling) to determine the level of some cytokines and enzymes. In this study, the levels of cytokines IL10, IFN-Y, TNF-α, TGF-β and the antioxidant enzymes glutathione reductase and glutathione peroxidase were measured in the saliva and serum of three patients with alopecia totalis by ELISA. Comparison of the levels of these substances in saliva samples at 5 am, saliva at 11 am and serum at 11 am with Friedman test did not show a significant difference. Therefore, saliva samples may be a good alternative to serum in the study of immunological factors.
