Increasing applications of electric and electromagnetic fields have caused some anxieties in human health. This research work has been done on the effects of 0.04 T and 0.06 T intensities with 50HZ frequency in blood cell of adult NMRI mice. In this work solenoid coils to produce electromagnetic fields were used two experimented groups (n=12) were exposed to electromagnetic wave four hours a day for 28 days. The results of experimental groups were compared with sham groups (n=6) and controls (n=6). Electromagnetic investigation of blood cell showed significant decrease of red blood cell(RBC) , white blood cell(WBC) , platelet (Pt) , hemoglobin (Hb) and MCHC (pandlt;0.05) in 0.06 and 0.04 mT electromagnetic field compared with sham and control groups. The amount of MCV and MCH increased at the same field significantly. Mean value of hematocrit in different groups did not show significant change.Results of this research work showed electromagnetic field could effect on the blood cell, As a result of damage on liver cells because of being exposed electromagnetic were this change will happen.

Ecological efficiency is the product of the efficiencies with which organisms exploit their food resources and convert them into biomass. (E.Ricklefs andamp; L.Miller , 1999). This survey was accomplishing during for seven month on the 20000 ha of the south part of the Sabzevar region. The lizards captured on 4 one-ha plots (I-II-III-IV) that were chosen to represent two kind of vegetation (include of shrubs and bushes). Plots I, II placed at shrubs vegetation (Tamarix hispidaandHaloxilon aphyllum) and plots III, IV placed at bushes vegetation (Peganum harmalaand Cousinia sp). Lizards were sampled by 2 methods. The first method consist of padding, repeated search of areas during 2 days (on morning, noon and after noon and night). Nearly all encountered lizards were captured by noosing or by hand. The second sampling method was accomplished with pit-fall trapping. Twenty pitfall traps were established in each plot. All traps were plastic buckets (20 cm diameter and 18 cm length). Traps were placed at random-systematic within a plot, buried in the ground, and leveled with the soil surface. Traps were checked each 3 days. Finally each captured lizard was weighed and data analyzed with ANOVA method (by SPSS software). Outcome of analyze demonstrator that mean of lizard biomass in each of plots I,II is different with plots III,IV,{I III,IV andamp; II III , IV} , in addition , it is true for the sum mean of I,II and III,IV, {I,II andamp; III,IV}.

In the present study, the effects of muscarinic agents on WIN55, 212-2 induced state-dependent memory of passive avoidance task were examined in mice. One-trial step-down paradigm was used for the assessment of memory retention in adult male NMRI mice. Post-training intra-CA1 administration of cannabinoid receptor agonist, WIN55, 212-2 (0.5 and 1 andmicro;g/mouse) decreased the memory retrieval. Amnesia induced by post-training WIN55, 212-2 (1andmicro;g/mouse) was significantly reversed by pre-test administration of WIN55,212-2 (0.5, 1andmu;g/mouse, intra-CA1), and induced WIN55, 212-2-state-dependent memory. Administration of scopolamine (4 andmicro;g/mouse) but not physostigmine (0.25, 1 and 4 andmicro;g/mouse) intra-CA1, 5 min before test by itself decreased the memory retrieval. On the other hands, the animals in which retrieval was impaired, due to WIN55, 212-2 (1andmicro;g/mouse) post-training administration, pre-test administration of physostigmine (1 and 4 andmicro;g/mouse) and scopolamine ( 4 andmicro;g/mouse) intra-CA1 24 hr after train in dayandrsquo;s test restored, memory retrieval. Furthermore animals under influence of post-training administration of WIN55, 212-2 (1andmicro;g/mouse), pre-test co-administration of non-effective doses of WIN55, 212-2 (0.25 andmicro;g/mouse) and scopolamine (1 andmicro;g/mouse), increased the restoration of memory by the WIN55, 212-2. These findings may implicate the involvement of muscarinic receptor in state-dependent memory induced by intra-CA1 administration of the WIN55, 212-2. Manuscript profile

Amphibians and reptiles are very important in biological control. Because of richness of fauna and flora in Mazandaran province and since many parts of it have not been studied yet, this research was done in order to identify the amphibians and reptiles in Shahid Zaree National Park of Sari during 2006-2008. This park located in southern part of Sari-Gorgan road, east of Sari city. There are no permanent rivers in this area, but just some shallow rivers produced by rain are observed in it. More than 200 specimens of amphibians and reptiles were collected by hand from different parts of park and most of them were released after identification and only a few of them transferred to zoological laboratory of Islamic Azad University-Damghan branch. Pictures and slides were taken from the live samples, and then specimens were fixed and preserved in 10% formalin.17 identified species belong to 10 families including: Rana macrocnemis, Rana ridibunda, Bufo variabilis, Emys orbicularis, Mauremys caspica, Drevskia chlorogaster, Lacerta strigata, Cyrtopodion caspium, Anguis fragilis, Pseudopus apodus, Dolichophis jugularis, Platyceps najadum, Gloydius halys, Telescopus fallax, Natrix natrix, Natrix tessellata, Typhlops vermicularis. Rana macrocnemis among amphibians and Lacerta chlorogaster among reptiles have the most frequency.Telescopus fallax was reported in Mazandaran province for the first time. Manuscript profile

In recent years, different methods have been employed to prevent pregnancy with ultimate aim of controlling human population. Treatment of some disease by alternative medicine as opposed to the traditional medicine associated with unwanted side effects has been found helpful. Use of FoeniculumVulgare has been identified as tranquilizer, anti spasm, elimination of digestive difficulties and reduction of maleandrsquo;s sexual hormones. Therefore, this investigation was mainly conducted to measure the possible effect of this Herbaland#39;s extract on maleand#39;s hormones production. In this research, several rates were divided into four experimental groups and one control group. Experimental groups were injected with 35, 70, 140 and 280 mg/Kg of this herbal extract and the control group received only saline. The results showed that the testosterone and LH level in experimental groups from dosages of 35 to 280 mg/Kg had meaningful decrease differences not only in first but also in second week. On the contrary, no difference was observed between the experimental group with 35 doses and the control group. The result showed that the meaningful differences also existed in the FSH hormone level between experimental group with 280 mg/Kg and the others groups just in second week. Manuscript profile

Hawksbill turtle (Eretmochelys imbricata (is one of endangered sea turtles that spawns in Persian Gulf coasts. This study has done during reproductive season of this species (March 2005 to June 2006)in Shidvar Island that is one of most important nesting area in Iran. During this study, nesting parameters of 35 female hawksbill turtles such as nests depths, number and weight of eggs, incubation time and hatching success rate were measured. In this island, clutches had an average of 92 eggs per clutch with mean of mean egg weights 32.94g and a mean of egg diameter of 38.49 mm. the average of incubation time and hatching success were 57.3 and 73.6% respectively. These data show that hawksbill eggs and hatchlings in Shidvar Island and also other parts of Persian Gulf are bigger and larger than other parts of world. These data confirm that Shidvar Island is of tremendous biodiversity importance. This is enhanced by the fact that it is not subject to human habitation and is relatively free from eggs and hatchlings predators. The likelihood that successful conservation of this island can play a positive role in safeguarding regional hawksbill populations is high. Manuscript profile

The importance of child care after birth and feeding them canandrsquo;t be stressed anymore. Meanwhile the process of lactation is the most crucial aspect of child feeding. In contrast the lack of healthy and enough food to the child is so vital which needs to be considered. There are so many remedies needed to improve and increase the lactation of mothers. Usually eliminating this deficiency has done through the use of chemical medicine. Side effects resulting from the use of these medicines have led us to use herbal medicines instead. Fennel for example is one of them. We have used in this study 75 mature female rats which are 2 to 3 month old and their proximate weights are (180-200). These rats divided into four experimental and one control group. The experimental groups have respectively received 35, 70,140 and 280 micro liters of the hydro extract of Fennel in the time periods of 5, 10 and 15 days. At the same time, control group have received physiologic serum in the form of IP. During the test, after 5, 10 and 15 days, the animals had a blood test in order to have their hormone measured and to determine the rate of Prolactine hormone. During the test, children have weighed daily in given times. Finally, the effects of fennel on lactation have measured through two options. 1. Motherandrsquo;s Prolactine hormone changes. 2. Childrenandrsquo;s weight changes. Tukey, Dunnett tests have used in order to review the statistical results. The differences between values in the level of (pandlt;0.05) and for the Dunnet test (pandlt;0.025) have been shown. Finally hydro extract of fennel didnandrsquo;t have significant effect on lactation in female Rat. Manuscript profile
