the removal of organic precursors of disinfection by-products (dbps), i.e. natural organic matter (nom), prior to disinfection is considered as the most effective approach to minimise the formation of dbps. trihalomethanes (thms) as the main group of dbps are categorized and considered to have the potentiality of increasing the rate of liver, kidney and cns adverse effects. this study which pre...

a b s t r a c tintroduction: because of more exposure to mercury compounds, the prenatal and postnatal neurotoxic effects of mercury compounds have gained more attention in last decade. the aim of this study was to investigate the effects of mercuric chloride intoxication on spinal cord development during prenatal period. methods: 36 adult sprague-dawley rats after observing vaginal mating plaq...

topical solutions containing aluminum chloride are known to be the first line of therapy for hyperhidrosis. palmar hyperhidrosis however, is less responsive to aluminum chloride therapy and successful treatment may require 6-8 h application of high concentrations up to 30% that commonly leads to skin irritation. the purpose of this study is to investigate the effect of 30 min iontophoretic appl...

regarding many disadvantages of traditional method to produce concentrated yoghurt, several attempts have been done for mechanization of process in industrial scale. using membrane systems especially ultra filtration is one of these methods. in this survey, method to produce direct concentrated yoghurt, fresh milk was concentrated to 19% snf by ultra filtration method then diluted to 13 and 16 ...

67gallium-bleomycin complex (67ga-blm) was prepared using thakour method. radio-thin-layer-chromatography of prepared complex showed a2 and b2 radiopeaks with rf at 0.7 and 0.4 respectively with a purity of above % 95. tissue uptake of 67ga-blm and 67gacl3 in twelve tissues including tumor, blood, liver, lung, spleen, muscle, skin, heart, kidney, colon, colon content ,bladder and the total body...

oral supplementation with 50, 100 and 150 ?g/ml calcium chloride to the fifth stadium larvae of csr2xcsr4 biovoltine hybrid silkworm, b. mori on fat body glycogen, protein, and total lipids and haemolymph trehalose and protein have been studied. one of the four normal feeds per day was substituted with treated leaves fed to silkworms at fifth instar larvae. the controls were fed with the leaves...

conclusions considering possible side effects of heparin and the increase in treatment charges and the fact that using heparin did not have a significant effect on patency and survival of catheters in the studied patients, it is recommended to use normal saline solution to maintain the patency of central venous catheters. results there was no significant difference in the rate of flushing (p = ...

background edible salt is the most commonly used food additive worldwide. therefore, any contamination of table salt could be a health hazard. objectives the present study aimed to determine the levels of heavy metals in table and bakery refined salts. materials and methods eighty-one table refined salt samples and the same number of bakery refined salt samples were purchased from retail market...

A technique is described for study of the kinetics of lateral transport of ions across single roots of corn, Zea mays, in short term experiments under steady state conditions. The kinetics of chloride transfer to the vessels reflected the kinetics of absorption of chloride by the root cells. Efflux from the root vacuoles contributed to only a small extent to transport of chloride into the exuda...
