[Study of awareness towards and the pattern of milk consumption in 7-12 year old elementary school students in the city of Sari and their mothers [2005-2006]]

Today, most societies face significant decrease in consuming milk products in children and this process would cause problems in providing the calcium needed by children, particularly since the osteoporosis is definitely connected to a lack of receiving sufficient calcium in children and adolescence age. Therefore, the goal of this study is to study the knowledge and pattern of milk consumption in 7-12 year old children of Sari and their mothers. The research samples consisted 638 male and female student at 7-12 in elementary schools [urban and rural], chosen at random from 16 schools. Necessary data were obtained through separate and different questionnaires on the output of milk consumption and its products through direct interviews. The data of the study were analyzed using t-Test, ANOVA, Duncan follow up, Chi-square and correlation coefficient. In this study, 44% of children and 37.7% of mothers consumed milk and 50.1% of children and 19.4% mothers sometimes consumed milk. 5.5% of children and 19.4% of mothers did not consume milk. Mostly, the reason for non-consuming milk among children and mothers was: not having access to milk [27.9% and 17.7%]. The awareness towards the advantages of milk was desirable in 67% children and 48.7% of mothers. It was almost desirable in 21.1% children and 4.5% of mothers and undesirable in 1.4% of children and 1.1% of mothers. The amount of milk consumption for 62% of urban children and 49% of rural children was only one unit, and, in sum, the amount of milk consumption for 59% of boys and 55% of girls was less than the recommended figures. The mean average of criteria deviation in the amount of milk consumption for children showed a significant difference from their educational levels [p=0.001] and insignificant difference from their sex. In addition, the pattern of milk consumption of children had significant relationship with the sex, education level and education of father; however, it had significant relationship with the education level of mothers and the jobs of mother and father. Children's knowledge about the advantages of milk had a significant relationship with the education level of mothers, fathers and jobs of mothers [P<0.004]; however, it had a insignificant relationship with their sex. In this study, the amount of milk consumption in half of the population subjects of the study was less than the standard recommended amount; therefore, to improve children's health status and prevent the destructive effects of osteoporosis in adulthood, there should be necessary actions to increase milk consumption among children

[Investigation and measurement of pesticidal residues; benomil and mancazeb in cucumber produced in Mazandaran]

Considering the importance and usefulness of fruits in people's daily diet as they play an important role in determining public health and also considering the significance of pesticide residues in foods and fruits, measurement of which has been repeatedly reiterated by WHO and FAO, this research was done. Irregular use of pesticides by farmers knowingly or unknowingly without observing its caress period has led to the contact of these pesticides with humans through foods and fruits and in the long run, they will surely cause chronic complications. In this study, after collecting cucumbers form 76 sample regions, we rinsed them carefully, sliced them thinly and mashed them up. Then, we extracted them three times with n butyl acetate. Later, we evaporated the solvent. At the end, we measured the residue by chromatographic gas [GC] and detector [ECD]. The results obtained were analyzed with the help of two-way ANOVA. It indicated that there is a correlation between the investigated regions and the residual amount [P>0.05]. Calculation of the mean ratings showed that the levels of these two pesticides are higher than the acceptable level in most of the regions. [0.01]

[Effect of methanolic extracts of Artemisia aucheri Boiss, Zataria multiflora Boiss and Myrtus communis L. on Trichomonas vaginalis [In Vitro]]

Considering the high prevalence of Tricomonas vaginalis [TV] in women and the known side effects of metronidazol, herbal drug therapy in order to reduce drug side effects has been considered increasingly in recent decades. This study was done to determine the effect of Artemisia aucheri Boiss, Zataria multiflora Boiss and Myrtus communis L. on Trichomonas vaginalis. This study was done on samples extracted from 100 patients with vaginitis due to Trichomona. The parasite was isolated from vagina and determined directly. Identification was done through direct smear preparation. Parasite was added to the 5 test tubes containing Dorse medium, metronidazole. dimethyl sulfoxaide [DMSO], Artemisia, Zataria and Myrtus extraction with concentration of 0.1, 0.01 ml in order to determine the effect of these concentrations within 72 hours. Trichomonas could be alived in Dorse medium for 72 hours, in presence of metronidazole for one hour and in Dorse medium for 6 hours. Also, methonolic extracts of Artemisia are effective at concentration of 0.1 after one hour and 0,01 after 4 hours of the inoculation. Methanolic extracts of Zataria at concentrations of 0.1 and 0.01 and the Myrtus extract at concentration of 0.1 are effective at beginning of inoculation but the Myrtus extract at concentration of 0.01 is effective after one hour. Considering the acceptable effect of methanolic extracts of these plants on trichomonas in in-vitro conditions, it is recommended that, the therapeutic effects of the substances from these plants to be studied in in vivo conditions and in case of having positive effect to be used as a drug

[Evaluation of chubak aqueous extract in parasite decontamination on vegetables and comparison with commercial detergent in Sari]

Use of surfactants and chemicals for washing and parasite decontamination from vegetables is not recommend-ed by W.H.O. due to it's penetration in vegetables parenchyma and probable cause of improper taste and odor and toxicity. Some surveys showed "soap-roots" rhizomes [Chubak] to contain Saponin like constituents. Those are effective on surface tension reduction and so are prefered to chemical washers. This research was designed to study plant effect on Parasite removal from vegetables and it's comparison with disinfectant and commercial detergent in Sari City [Mazandaran Province-north of Iran]. "Soap-roots" aqueous extract [1, 5, 10, 15, and 20 percent] was prepared from the Acanthophyllum squarrosum [Caryophyllaceae] rhizome by maceration method. 100 g of parsley vegetable samples was taken randomly from shopping centers. The samples were placed in contact with "Soap-roots" aqueous extract for zero and 15 minutes according to the W.H.O. guidelines. Then the effluent was centrifuged and evaluated for parasite decontamination as qualitatively and quantitatively by Mc-master counting slide [0.3 mm]. In addition in this research parasite decontamination by commercial detergent [10%] was performed with contact times 0 and 15 minutes and also pure water as blank. Maximum parasite decontamination by "Soap-roots" aqueous extract and commercial detergent [10%] at 0 minute contact time obtained was 84 and 97 parasite eggs [parasite], respectively. Also maximum parasite decontamination by "Soap-roots" aqueous extract and commercial detergent [10%] and blank water at 15 minutes contact time obtained was 230, 26 and 64 parasite ova [parasite], respectively. In this research the best parasite decontamination range by "Soap-roots" aqueous extract was obtained at concentrations of 10 to 20% and contact time of 15 minutes. Quantitavely, maximum parasite ova [parasite] decontamination from vegetable samples by "Soap-roots" aqueous extract [10%] and 15 minutes contact time released 230 parasites. This numbers included 22 alive and active nematode larva, 197 alive larvas and 20 Parameciumia
