  Children who are born with Intrauterine Growth Retardation (IUGR) have higher rates of seizures, sepsis, respiratory failure and neonatal mortality. The aim of this study was to determine risk factors associated with IUGR. This was a case-control study that carried out in Shariati Hospital of Bandar Abbas. Sixty IUGR and 60 normal birth weight infants were selected in the delivery room. The first normal birth weight baby born, after an IUGR baby, was taken as a control. A structured questionnaire was used to collect socio-demographic data, maternal data including past obstetric history, current pregnancy and delivery data, as well as data about the newborns. Data were analyzed using SPSS version 13 software. Risk factors associated with IUGR in this study were maternal work (OR = 10.2, CI 95% = 1.2-87.3), to have hypertension (OR = 7.4, CI 95% = 1.5-36.9), to use hookah during pregnancy (OR = 3.5, CI 95% = 1.1-12.6) and not to use antenatal care (OR = 3.9, CI 95% = 1.2-13.7). Screening women for known risk factors of IUGR, counseling, health education about risks of IUGR and the ways of prevention is necessary to reduce the rate of it.

  In this study samples of three commonly consumed fish ( Sefid, Kafal and Koli ) were analysed for concentrations of heavy metals (Pb, Cd and Cu). Fish were captured using electric fishing on four sites along the Tajan River (Mazandaran province). The concentrations of heavy metals were determined by atomic absorption spectrophotometer. Samples contained detectable concentrations of heavy metals but at concentrations below the Maximum Residue Limit (MRL). Cadmium concentrations were below the MRL. Lead contamination showed no significantly different. Copper contamination was correlated with the localization of industrial plants. With respect to concentrations of pollutants in the Tajan river should not pose a serious threat to the fishes and public health.

  In this study concentrations of Parathion (organophosphorous pesticides) was determined in four commercially valuable fish species, Rutilus frisikutum, Clupeonella delicatula, Mugila auratus and Vimba vimba, from four sites of Tajan River in July 2004. The concentration of parathion was measured by gas chromatography electron-capture detection (GC-ECD). Concentrations of the parathion in examined fish species ranged from 5.94 (site III) to 49.57 (site IV) lg kg-1 (wet weight). No difference found between kind of fishes in each sites about parathion concentrations but there are two groups of sites that were significantly different from one another in terms of parathion concentrations: sites 2, 3 and 4 < site 1 (p<0.05). Parathion in the edible parts of the investigated fish were in the permissible safety levels for human uses and should not be public concern among peoples in Mazandaran province.

  The aim of this research was to evaluate the amount of lead in the tissue of Astacus leptodactylus especially in their muscle which the consumed part of their body. In this study the crayfish was exposed to intermediate concentration of lead nitrate (500 μg L-1) for periods up to 3 weeks. In the first, second and third weeks bioaccumulation in various tissues was under investigation. The data of toxicological analysis obtained by the method of atomic absorption revealed that the levels of bioaccumulation of metal are different in various tissues of this crayfish. The accumulation of the lead in gills was the highest and in muscles was lowest degree. The amount of heavy metals in the tissues of crayfish was as follow. Gills>exoskeleton>hepatopancreas (digestive glands)>digestive tract>green gland>testis and ovary>muscles.

  Due to different human activities in the vicinities of Aras dam, various pollutants such as heavy metals are entered into the reservoir and thus polluting the aquatic ecosystem. As a result, this heavy metal is accumulated in the tissues of Astacus leptodoctylus, which is considered as one the abundant species of crayfish that has got important food values and is of economic importance due to its export to other countries. In this research, the bioaccumulation of heavy metals in different tissues of this animal is taken into consideration. The concentration of Fe, Cu, Zn, Mn, Pb, Ni, Co and Cr among the tissues of female and male Astacus leptodactylus has been determined. The highest concentration of Cu and Fe was found in the gills and the highest level of Zn was found in hepatopancreas. Besides, the highest Mn concentration was recognized in exoskeleton. Furthermore, no significant difference was found between the male and female crayfish in the concentration of the heavy metals in their tissues, except for the concentration of some of the metals such as Fe in some of the tissues such as hepatopancreas.

  One of the effects of industrialization of communities is great consumption of different chemical substances that resulted severe consequences such as, chronic poisoning that most of them will be dangerous and life threatening. The metals are part of major substances with mutational and carcinogenic effects. With respect to the collective characteristics of these metals on human and environmental health, we decided to evaluate their adverse effects. Present study was done in Gillan province (North of Iran) on green leaf of Tea cultivated in Lahijan and Fuman cities. The samples were selected from ten regions and five samples from selected areas were studied. evaluation of metals in green leaves (Pb, Cd, Cr and Zn) was carried out by atomic absorption spectrometry .The results showed a significant relation between the amount of lead and regions (P < 0.05) and also comparison between these mean numbers showed that in Eastern station, lead had the highest amount with average of 5.300 ppm in Fuman and 4.300 ppm in Lahijan samples. Amounts of other metals (Cd, Cr and Cu) were below standard that proposed by WHO. With respect to obtained results, there is a great potential for hazardous substance in the studied regions and it is necessary to make a serious analysis about this substances in other regions of Gillan Province.

  In this study samples of Cucumber (Cucumis sativus L.) were analyzed for concentrations of lindane (organochlorine pesticides). Samples were gathered on four sites in Sari city (north, south, east, west and central areas) in Mazandaran province of Iran. Quantitative determination of the lindane was performed by gas chromatography electron-capture detection (GC–ECD). Samples contained detectable concentrations of lindane but at concentrations below the proposed limit by WHO. No significant difference was found between sites about lindane concentrations but Central area showed maximum level in lindane concentrations (p < 0.05). Concentrations of lindane in cucumber sampled in this study should not be public concern among peoples in Mazandaran province.

  The anthocyanin pigment was extracted from the four different Berberis plant (B. khorasanica, B. integerrima, B. orthobotrys, and B. vulgaris) using the soaking and wetting in Ethanol (1% acidified). The extracted anthocyanin pigments then were exposed to number of environmental conditions, which could destabilize the anthocyanin molecules. These environmental conditions were included three different pHs (0, 1.5 and 3), various temperatures (5oC, 15oC, 25oC and 35oC) and presence or absence of light. The results of the study showed that increasing in pH, temperature or exposure to light is able to spoil the anthocyanin molecule. Another factor affecting the tolerance of anthocyanin towards the environmental condition is the role of different species. Among the various Berberis species anthocyanin pigment in B. khorasanica, showed the greatest resistance to destruction by environmental conditions followed by B. vulgaris, B. orthobotrys, and B. integerrima.

  Echium amoenum (Boraginaceae) is a very popular medicinal plant which is used as a tonic, tranquillizer, diaphoretic, cough remedy, sore throat and pneumonia in Iran`s traditional medicine. Preliminary phytochemical study of the plant, with standard procedures, showed that it contains saponins, flavonoids, unsaturated terpenoids and sterols. There was no evidence of tannins, alkaloids and cyanogenic glycosides. In this study an aqueous extract from petals of this botanical was used in 125 mg kg 1 concentration as compared with diazepam 1 mg kg 1 intraperitonealy (i.p.), during 2 different treatment courses, 15 and 30 days. Anxiolytic effect of extract was investigated in Rat using the elevated plus maze model of anxiety. After finishing these courses and 30 min after last injections, the test performed. Results revealed that in 30 days treatment course, time spent in open arms was significantly higher than 15 days treatment in all groups and this effect is lower than diazepam. So we showed a significant time-dependent increase in time spent in open arm.

  Echium amoenum belongs to the Boraginaceae family and is a biennial and perennial herb indigenous to the narrow zone of northern part of Iran and Caucasus. The flowers and leaves of this plant are used medicinally as ant febrile, anti-depressive, for the treatment of stress, laxative and anxiolytic. In this study we prepared an aqueous extract from dried petals of this botanical in 125 mg kg 1 concentration (effected dose on anxiety on basis of other researches) and tested the effect of extract on motor coordination in Rat as compared with diazepam 1 mg kg 1 as sedative and synthetic drug. Rotarod apparatus used in this study. The experiment did during 15 and 30 days. Statistical analysis of the latency to fall from the rotarod revealed that intraperitonealy administration of E. amoenum in 125 mg kg 1 and diazepam 1 mg kg 1 produced motor in coordination in 15 days but motor coordination in 30 days compared to control group.
