This study focuses on endoscopic and pathologic alterations of gastrointestinal (GI) disorders of Iranian patients with common variable immunodeficiency (CVID). Nineteen of 39 CVID patients (48%) had GI complaints. The most common symptom was chronic diarrhea (28%). In endoscopic examination of small intestines, 15 patients had no abnormal finding. Duodenal biopsy revealed villous atrophy in eight and nodular lymphoid hyperplasia in three patients. There was no statistically significant difference between patients with and patients without duodenal villous atrophy regarding the presence of chronic diarrhea, anemia, and absolute CD4+T cells. In three patients, biopsies of the colon showed chronic noncrypt-destructive colitis. GI problems pose a high morbidity to CVID patients and are second only to respiratory complications. CVID patients are at increased risk of infectious and inflammatory conditions in the GI tract. Early diagnosis of these complications improves the quality of life and well-being of patients.
The present study was conducted to investigate the effects of fenugreek seed meal (FKSM) on growth performance, blood haematological and biochemical factors, survival and stress resistance of the common carp (2.46 AE 0.06 g) fingerlings.Four practical diets containing 0 (control), 0.5%, 1% and 1.5% FKSM were used to feed fish. Fish were fed on the tested diets at a rate of 3% of body weight for 8 weeks. Results indicated that fish fed the control diet had a significantly lower weight gain, specific growth rate and condition factor compared to the other treatments (P < 0.05). Feed conversion ratio decreased significantly in fish fed diets containing FKSM. There were no significant differences in glucose levels, red blood cell count, haematocrit and haemoglobin between treatment groups and the control group (P > 0.05). Significantly lower white blood cells count was observed in fish treatment with FKSM when compared with the control group (P < 0.05). The cholesterol level in group fed supplemented diet by 1% fenugreek significantly lower than other groups (P < 0.05). Total protein levels were significantly higher in all treatments compared to the control (P < 0.05). No mortality was recorded during the feeding trial. In salinity stress experiment, highest survival rate belong to fish fed supplemented diet by 1% fenugreek. These results indicate that FKSM can be considered as a beneficial dietary supplement for improving the growth performance and blood indices of common carp fingerling.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
