The aim of the present study was to evaluate the potential toxicity of Cefuroxime (CFR), a second-generation cephalosporin antibiotic, on ovary of ‘wistar’ rats. A total of 32 adult female rats (12 weeks old) were intraperitoneally injected with CFR at a dose of 0, 30, 60 or 120 mg/kg, divided into two equal doses daily, for 7 days and sacrificed 24 h after the last dose. Biochemical assays showed significant reduction in oestradiol and progesterone levels in compari...

Kalach 360 SL (KL), glyphosate (G) surfactant-based herbicides, is a systemic herbicide effective against weeds. It was applied in agriculture in Tunisia and throughout the world, which can represent a risk to non-target organisms. The aim of this study was to investigate the morphological and biochemical aspects of ovary injury after exposure to KL. Female Wistar rats were divided into three groups: group 1 was used as a control; group 2 orally received 0.07 ml of KL, (126 mg...

The present study aimed to investigate the effect of time-of-days (TOD) on some biochemical and hormonal responses after resistance training sessions.Methods: Ten trained subjects performed three resistance-training-sessions at 0700 h, 1300 h and 1700 h. Each training-session included six upper and lower body resistance exercises with 3×10 repetitions. Blood lactate (Lac), creatine kinase (CK), lactate dehydrogenase (LDH), cortisol (C) and testoster...

Introduction: Liver abnormalities are rarely observed in thyrotoxicosis. Diagnosis should be considered only after outruling other possibilities of hepathic pathology, especially autoimmune disaese. We report the case of a 6-year-old girl with Graves’ disease who presented a liver dysfuntion.Case report: A 6-year-old girl with a history of Graves’ disease diagnosed and treated 15 days before, was admitted for jaundice and pruritus. The interrog...

Objective: Considering that the patients with Turner syndrome (TS) have a high prevalence of autoimmune disease, an early investigation for digestive system diseases should be carried out in those with TS.Case 1: A 13-year-old girl, followed for Turner’s syndrome with characteristic facial dysmorphia, developed glaring diarrhea. Colon and endoscopic endoscopic examinations have led to ulcerative colitis. It was put pentasa with a favorable evolution...

Introduction: The association of primary hyperparathyroidism (PHPT) and hyperthyroidism secondary to toxic multinodular goiter (TMNG) is rarely described in the literature. Hereby, we describe the clinical, biological, and radiological characteristics of two patients having this rare association.Observations: First case: A 66 years-old female was diagnosed with primary hyperthyroidism. Her thyroid antibodies were negatives. During the follow-up, she pres...

Autoimmune thyroid diseases (AITD), which include Hashimoto thyroiditis (HT), Graves’ disease (GD) and primary idiopathicmyxoedema (PIM), are recognized by their clinical and genetic heterogeneity. In this study, we have carried on a global approach gathering 20 year genetic and clinical data on a Tunisian multigenerational family (Akr). Our purpose was search for a combined genotype involved in AITD susceptibility using 33 gene polymorphisms. The Akr pedigree is composed...

We aimed to identify causal mutation(s) in 13 patients with thyroid dyshormonogenesis (TD) from three consanguineous Tunisian families. A 12-year clinical follow-up showed phenotypic variability ranging from the presence to the absence of goiter, sensorineural deafness, and mental retardation. Genetic analysis using microsatellite markers within two candidate genes (TPO and PDS) gave evidence of linkage with the TPO gene. Sequencing of its 17 exons and their flanking intron-ex...

Introduction: Dysthyroidism is not uncommon during chromosomal aberrations. The objective of this work is to study the characteristics of this association at the epidemiological and clinical levels.Methods: This is a retrospective study of 27 cases of patients with trisomy 21 chromosomal abnormalities (6 cases), klinefelter syndrome (4 cases) and Turner syndrome (17 cases) genetically confirmed, collected at endocrinology service at Sfax University Hospi...

Introduction: The magnesium deficiency is frequently associated with diabetes mellitus, it is also incriminated in the occurrence of diabetic complications (micro and macrovascular). Our objective was to study the correlation between magnesium deficiency (Mg) and the presence of chronic diabetic complications.Material and methods: Prospective study that concerned type 2 diabetics (T2D). Our patients were subdivided into 2 groups G1 and G2: G1 including 1...
