Introduction: Basal cell carcinoma is the most common malignancy in humans. A number of treatment modalities are available. We performed this study in order to determine the efficacy of Mohs micrographic surgery in treatment of basal cell carcinoma.
Materials and Methods: This retrospective descriptive study was performed on 194 basal cell carcinoma (in 175 patients) were treated in Isfahan Al-Zahra Hospital from september 1999 to March 2003 with Mohs micrographic surgery. Data were obtained from patient's files and were analized by SPSS software.
Results: Of the 175 patients (with 194 basal cell carcinomas), 110 (62.85%) paticnls were male and 65 patients (37.14%) were females. The mean age of patients was 58±12.38 years. The majority of tumors were located on face and scalp. 180 of tumors were primary and 14 were recurrences. 17% of tumors were larger than 2cm. Recurrences of the tumor occured in 3 patients. The cosmetic results were excellent and good in 81%. The incidence of recurrnce rate was 0.9%.
Conclusion: Kecurrence rate is low when basal cell carcinomas treated with micrographic surgery so this treatment modality (when indicated) is also strongly recommended in Iran for the treatment of basal cell carcinoma.

Introduction: Androgenetic alopecia is a very common disease. According to some reports, up to 96% of people have some form of this disease. In this paper we compared the effect of an herbal drug composed of the urticadioica, chamomilla, thymus vulgaris, equisetum arvense and foeniculum vulgare with 2% Minoxidil solution in the treatment of androgenetic alopecia.
Materials and Methods: We evaluated 82 patients suffering from androgenetic alopecia in a double blind prospective study. We counted terminal and vellous hair in 1 square centimeter of the predetermined area of scalp before and after treatment. After 6 months of treatment, the results were evaluated
Results: According to our findings, herbal drug and Minoxidil were effective in regrowthing the hair (45% vs. 35% respectively) and there were no meaningful differences between efficiacies of these two drugs
Conclusion: Herbal drug can be used as an adjunct or as an alternative to Minoxidil for treatment of the androgenetic alopecia.

Introduction: Some articles have suggested an increase in the prevalence of oral candidiasis in patients with psoriasis, as well as the potential for exacerbation or chronicity of psoriasis. Therefore, the prevalence of oral candidiasis in patients with psoriasis and its comparison with healthy individuals has been considered.
method: In this cross-sectional study, 43 people with psoriasis and 43 seemingly healthy individuals referred to dermatology clinics affiliated with Isfahan University of Medical Sciences were randomly selected and examined for the presence or absence of Candida albicans in the oral mucosa by direct lam and culture. Were placed.
Results: According to the results of this analytical study, 44.2% of patients with psoriasis with Candida albicans were infected with oral cavity, which was 25.6% for healthy individuals, and this difference was significant (p=0.05). There was also a significant relationship between the severity of psoriasis and the prevalence of oral Candida albicans (p=0.05).
Conclusion: The study found that candida yeast was more common in patients with psoriasis than in healthy people. According to the results of this study, it is recommended that all patients with psoriasis be examined for the presence of Candida albicans in the mouth and, if the test is positive, be treated with antifungal drugs.

Background: Due to concerns over the negative impacts of PCB compounds on environment and their persistence, their production, use, and import has been banned in some countries. More recently, the Chemical Treaty on Persistent Organic Pollutants (POPs) has listed PCBs among priority chemicals for eventual elimination by 2025. The aim of this study was to determine the effect of solvents on the photodegradation of askarel oils using photolysis for reducing their hazards. Materials and Methods: The photochemical reactor, used in this experimental trial, was based on photolysis through UV/ H2O2 with a 500 ml beaker and low-pressure mercury lamp with a wavelength of 254 nm. The lamp was immersed in the beaker. The temperature and PH of the samples were constantly monitored. The experiments were repeated three times. Askarel oils were analyzed by GC/ECD. Results: The means of degradation of total PCBs due to the use of lamp for ethanol solvent and isooctane were 88% and 77%, respectively. The mean degradation of total PCBs in terms of the applied solvent ratio to the oil transformer for 1:1, 2:1, and 3:1 values for ethanol and isooctane were 55%, 85%, and 88%, and 40%, 77%, and 78%, respectively. Conclusion: Photolysis of PCB compounds in the presence of ethanol solvents, isoocatnes with strong oxidants such as H2O2, indicated their degradation or reduction in oil transformers with lower energy, and no yield of toxic byproducts. There was a significant difference in the employment of ethanol solvent and isooctane in degradation of askarel oil.

Background: Poly chlorinated biphenyls (PBCs) are the group of organic chemical materials that have a great chemical stability. These compounds are hazardous pollutants which pose various occupational and environmental problems. This study was conducted to determine the effect of microwave rays, hydrogen peroxide, Tio2 catalyst, and ethanol on the decomposition of PBCs. Materials and Methods: In this experimental study, a vessel reactor (250ml volume)that was connected with a tube connector to thecondensor system was used. A microwave oven with a fixed frequency of 2450 MHZ was used to provide microwave irradiation and ray powers used at 540, 720 and 900w. pH and temperature of the samples were continuously monitored and the experiments were repeated three times. Askarel oils were analyzed by GC-ECD. Results: The mean of total PCBS degradation at 540, 720, and 900w was 83.88±1.63, 89.27±2.44, and 95.98±0.81%, respectively. The mean of total PCBS degradation in terms of ratio to solvent with oil transformer in 1:1, 2:1, and 3:1 was 53.8±3.26, 79.04±1.24, and 95.08±1.69%, respectively. The mean of total PCBS degradation in terms of not using H2o2/Tio2 and using H2O2 (20%) and 0.05, 0.1, 0.15, and 0.2 g of Tio2 concurrently was 71.47±0.81, 87.9±2.16, 89.48±1.69, 91.7±1.24, and 93.07±3.09 %, respectively. Conclusion: Using microwave irradiation in the presence of H2O2 oxidant and Tio2 catalyst leads to the reduction of PCBS.
