[Evaluation effect of different density auxin and fungi piriformospora indica and sebacina vermifera on mentha piperita and thymus vulgaris in vitro condition]

Mentha piperita and Thymus vulgaris are two important species of family Lamiaceae that abundantly used in pharmaceutical, food, cosmetic and hygienic industries. Objectives in this study were the effect of different concentration of auxin and fungi Piriformospora indica and Sebacina vermifera on the growth and development of peppermint and thymein vitro condition. Two distinct experiments were conducted; the first evaluate the effect of different auxin levels [IAA NAA IBA] on M. piperita and T. vulgaris growth, and the second examined the effect of two fungi Piriformospora indica and Sebacina vermifera on plant height, root length, shoots and root weight in in vitro in a completely randomized design. The first study suggested the most effective hormone dose for the M. piperita growth was 1mg per liter of IBA and in the T. vulgaris it was 1 mg per liter of IAA. Increasing of the hormone doses resulted in growth decrease. The second study evolved that growth of the plants inoculated with fungi increased significantly. The data indicated that the plants inoculated with S. vermifera were the highest of all and the plants inoculated with P. indica had the most weight. The nodes of M. piperita and numbers of shoots in T. vulgaris increased significantly. These results indicate that the best hormone for tissue culture peppermint and thyme are 1mg per liter of IBA and IAA, respectively. Also using these fungi can increase grow and development of plants

Laparoscopic treatment of polycystic ovaries with neeble cautery in clomiphen resistant patients [evaluatian of treatment results]

This study was conducted to evaluate the clinical and reproductive outcomes after Laparoscopic Ovarian Drilling [LOD] performance in infertile women with Clomiphene resistant Poly Cystic Ovary Syndrome [PCOS]. Regular menstrual cycles, ovulation and pregnancy rates have been considered as three main outcomes being evaluated in this study. 72 Clomiphene-resistant anovulatory women with PCOS in Karaj Hospital were taken into account in this study from 2002-2005. Laparoscopic Ovarian Drilling [LOD] using a needle cautery was performed. Each ovary was punctured at 6 points. Patients were followed for 24 months for evaluating the outcome. After laparoscopy, regular menstruation occurred spontaneously in 82.6% and maintained regular at least for 6 months. The incidence of conception at 6, 12, 18, and 24 months after surgery was 14.7%, 36.8%, 58.5%, 67.6% respectively. Laparoscopic ovarian drilling is an effective treatment in Clomiphene-resistant anovulatory women with PCOS

Caesarean section rates in teaching hospitals of Tehran: 1999-2003

To determine the trends of caesarean section in teaching hospitals of Tehran University of Medical Sciences, a retrospective analysis was performed on the obstetric data from 3 hospitals in a 5- year period. The caesarean section rate increased from 35.4% of deliveries in 1999 to 42.3% in 2003. The data showed that there was a steady increase in elective operations that might explain the rise in overall caesarean section rate
