Due to scarcity of human reports, we took advantage of the heaviest infection of M. moniliformis in rats, to describe histopathological and microanatomical valuable useful keys while confronting human occurrences. Samples were obtained from captured rats in Tehran, capital of Ira, during two dec­ades. Tissue sections were performed through hematoxylin and eosin staining to describe histopa­thological changes in rat's intestines. Totally, nine rats were found infected with M. moniliformis amongst 272 obtained rats. Heavy infection has been distinguished in 2 individuals with parasite burden of 141and 73 adult worms. Cross sections of worms within the lumen show mucosal thickness, infiltration of eosino­philic leukocyte and increase in goblet cells. Beyond the uncommonness of human infection with M. moniliformis unintended infections should not be ignored. Abundance of rats and roaches as definite and intermediate hosts must be considered particularly in countries with poor hygiene.

In this study the haemolymph components of infected and none infected Lymnaea gedrosiana with xiphidiocercaria larvae was compared. Five hundred Fifty Lymnaea snails were collected from Ilam and Mazandaran prov­inces, Iran, during 2008-2009. The snails were transported to the lab at Tehran University of Medi­cal Sciences and their cercarial sheddings were studied. Haemolmyphs of snails were ex­tracted and cells were counted using haemocytometer and cell-surface carbohydrate were recog­nized by conjugated lectin (Lentil). Haemolymph protein concentrations were measured by Brad­ford protein assay method and soluble protein compositions were determined on sodium dodecyl sulphate polyacrilamide gel electrophoresis (SDS-PAGE). From the 550 examined Lymnaea snails for cercariae, 27 snails were infected with xiphidiocer­cariae. Mean of haemolymph cells (haemocyte) number were obtained 93480±2.43 (cells/ml) for none infected snails (25 snail) and 124560±2800 (cells/ml) for infected snails (25 snail). Mannose carbohydrate was recognized on haemocyte of none infected and infected snails. Mean of protein concentration of haemolymph plasma was obtained as 1354 ± 160 μg/ml (1.4 mg/ml) for none infected snails (25 snails) and 1802±138 μg/ml (1.8 mg/ml) for infected snail (25 snails). Comparing to none infected snails, the SDS-PAGE results of haemolymph plasma of infected snails, showed an extra protein band (70 kDa). The results showed a significant differ­ence between the amounts and the kinds of proteins in haemolymph of infected and none infected snails. This information might be useful to understand of parasite detection, adhesion, engulf­ment and antigen agglutination by snail.

Recent studies indicate that Visfatin, a newly identified adipocytokine, may have potential proinflammatory effects. Since, the relationship between serum visfatin levels and metabolic syndrome (MetS) has not been established, the aim of this study was to explore the association between serum visfatin levels and anthropometric variables and the metabolic syndrome. Thirty-seven patients with MetS and 37 age matched controls (mean age 46.35±1.6 years) were included. Metabolic syndrome in patients was defined based on the 2005 criteria of the International Diabetes Federation, and anthropometric and biochemical profiles were documented. Serum Visfatin was measured using an enzyme immunoassay (EIA) kit. Using the t-test, data were compared between groups and Pearson's correlation coefficient was used to evaluate the relationship between continuous variables. P values <0.05 were considered as statistically significant. Serum Visfatin level was significantly lower in metabolic syndrome patients (P<0. 05) compared controls, log visfatin: 1.74 ± 0.27ng/ml vs. 1.86 ±0.13 ng/ml, respectively. There was no significant correlation between serum visfatin levels and any anthropometric or any metabolic parameters in patients with metabolic syndrome or the control group. The results of this study showed that serum visfatin level was decreased in patients with MetS, indicating that Visfatin cannot be considered as a new proinflammatory adipocytokine for the metabolic syndrome.
