Abstract
Background: Thyroid hormones play a critical role in hematopoiesis, and thyroid disorders such as hypothyroidism and hyperthyroidism can affect blood parameters. Therefore, this study aimed to evaluate the effect of thyroid dysfunction on various blood parameters.
Methods: This case-control study included 194 subjects who were classified into three groups based on TSH levels: hypothyroid (n=70), hyperthyroid (n=56), and control (n=68). Conditions that affect blood parameters, including pregnancy, inherited or acquired red blood cell abnormalities, chronic inflammatory diseases, evidence of nutritional deficiencies, and underlying diseases such as cancer, as well as patients unwilling to participate in the study, were excluded. Hematological parameters were measured using a cell counter, and the results were analyzed using SPSS software.
Results: The results showed that 78% of the participants were female and 22% were male, aged 4 to 89 years. The analyses revealed that RBC, Hb, HCT, WBC count, and WBC differential count were significantly different between the three groups (P-value <0.05), but the differences were not significant for MCV, MCH, MCHC, RDW, PLT, and MPV (P-value >0.05). Correlation analysis indicated a significant correlation between TSH and Hb, HCT, WBC, PLT, neutrophils, lymphocytes, monocytes, and eosinophils (P<0.05).
Conclusion: Since thyroid hormones play a critical role in hematopoiesis, thyroid dysfunction can affect many hematological parameters. Therefore, the management of patients with thyroid disease should include the CBC test. In addition, patients with poor responses to anemia treatment may have an underlying thyroid disorder.

Abstract
ABSTRACT 
Background and objectives: Lactic acid bacteria (LAB) are potential candidates for the mucosal vaccine. Staphylococcal enterotoxin B (SEB), as a potent superantigen exotoxin is associated with widespread dietary poisoning and induction of toxic shock syndrome. Also, cholera toxin is the most important virulence factor in Vibrio cholera pathogenicity. CTB, a well-known immune adjuvant, enhances immunity and is mainly used to produce recombinant vaccines as antigen immunization enhancers. This study aimed to produce recombinant Lactobacillus Plantarum as a candidate vaccine against Vibrio cholera producing Cholera toxin and Staphylococcus aureus producing enterotoxin SEB. Methods:  A gene sequence encoding  SEB, devoid of superantigenic activity, and CTB were successfully designed, synthesized, cloned, and then expressed in a secreted form in the Lactobacillus Plantarum. The recombinant protein containing His-Tag was purified by Ni-NTA Agarose ion-exchange chromatography column.  The purified protein was confirmed by Western blotting. Results: The result of this study demonstrated the expression of this recombinant protein in the Lactobacillus Plantarum system by pnz7021 expression vector. The protein electrophoresis showed that the molecular weight of recombinant fusion protein was 52 kDa. Western blot analysis also confirmed the production of recombinant protein. The use of recombinant vaccines has received a great deal of attention today. LP-pnz7021–SP-rseb-ctxB can be used as a suitable candidate in recombinant vaccines against Vibrio cholera producing Cholera toxin and Staphylococcus aureus producing enterotoxin SEB.
