Abstract
Abamectin (AB) is widely used in agriculture and has been employed as an insecticide, nematicide, and livestock pest control agent. However, it may also pose a serious threat to mammals. The primary purpose of this research was to compare the sex variations between male and female rats during exposure and to assess the risk of toxicity of abamectin, which are still largely unknown. The twenty albino rats were divided randomly into four groups (n = 5): 1) the male control group; 2) the male treatment group treated with AB (1 mg/kg B.W.); 3) the female control group; and 4) the female treatment group treated with AB (1 mg/kg B.W.). AB administration caused a drop in body weight in females more than males with showing oxidative stress in both sexes of animals, as characterized by an increase in MDA content and a decrease in glutathione (GSH) content and superoxide dismutase (SOD) activity. Reported sex-specific effects suggested that females are more susceptible from males in brain tissues for alteration of antioxidant markers while females' liver and kidney tissues showed more level of lipid peroxidation than males. In addition, mitochondrial dysfunction was associated with a significant decrease in NADH dehydrogenase (Complex I) and a significant decrease in mitochondrial ATPase, which led to apoptosis and histopathological alterations in the targeted tissues, indicating that females are higher sensitive than males to these biological events. In brief, the results of this study led to female rats are generally more sensitive than male rats to neurobehavioral and hepatic complications associated with abamectin treatment. Further evaluation should be performed to determine the adverse outcome pathways involved and to determine the effects of sex on improving the risk assessment of abamectin in both sexes.

Abstract
The testicular deficiency associated with exposure to three widely used insecticides in Egyptian agriculture was evaluated. Animals were orally treated with sub-lethal dose (1/50 of the oral LD50) of cypermethrin (CYP), imidacloprid (IMC), and chlorpyrifos (CPF) at 5, 9 and 1.9 mg/kg/day, respectively, five times a week for one month. The CYP, IMC, and CPF exposure resulted in a significant decline in animal body weight, sperm count, motility, normality, and viability with increased head and tail deformities. Significant reduction in serum testosterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH), testis superoxide dismutase (SOD), and reduced glutathione (GSH) levels. In contrast, catalase (CAT), lipid peroxidation (LPO), and protein carbonyl content (PCC) levels were significantly stimulated. Jointly, obtained results were confirmed by microscopic examination of testis sections. The present data concluded that the CYP, IMC, and CPF have a public health impact and violently interferes with male rat reproductive system.

Abstract
Several enteric protozoan species are linked to diarrhea in humans, with some causing debilitating illnesses, essentially in immunocompromised and neutropenic patients as in acute leukemias. The aim of this study was to detect intestinal protozoa in Egyptian neutropenic patients with acute leukemia. The study comprised two groups; 40 newly diagnosed neutropenic acute leukemia patients and 30 controls. Stool samples were collected from all participants and subjected to routine microscopic examination, special staining and detection of copro-antigen using rapid diagnostic test (RDT) RIDA®QUICK Entamoeba/ Giardia/ Cryptosporidium Combi. Cases were tested post-chemotherapy at the nadir of neutropenia (absolute neutrophil count ANC<= 0.5x109/L) and 19 cases were also tested initially prior to chemotherapy. Of examined patients, 15/40 (37%) were positive for Blastocystis hominis by wet mount, 10/40 (25%) had microsporidia using modified trichrome stain and only 2 cases (5%) of Cryptosporidium spp. by Ziehl-Neelsen stain. By RDT, 8/40 cases (20%) were positive compared to entirely negative controls. The positive cases included 4 patients with G. intestinalis 2 with Entamoeba and 2 with Cryptosporidium.19/40 cases were tested both pre- and post-chemotherapy. microsporidian spp. was diagnosed in 6/19 cases at the nadir of neutropenia compared to none of the cases pre-chemotherapy and the difference was statistically significant (p= 0.031*). Intestinal protozoa in acute leukemia patients post-chemotherapy are common especially B. hominis. Furthermore, RDT might be helpful for diagnosing intestinal protozoa in acute leukemia. Attention is highly required as intestinal protozoa infection can emerge after chemotherapy such as microsporidia.

Abstract
To test the role of T helper cell Th1 immunity we recruited 24 patients with idiopathic thrombocytopenia associated with H. pylori seropositivity. They were divided into 2 groups: 12 with immune-mediated thrombocytopenia (Group 1) and 12 with non-immune mediated thrombocytopenia (Group 2). We also recruited 10 individuals seronegative for H. pylori (Group 3) as controls. Initial platelet count was significantly lower in Group 1 than Group 2. H. pylori was eradicated in 10 of 12 patients in Group 1 and in all patients in Group 2. Transient improvement (< 3 months) in the platelet count occurred in only 2 patients in Group 1 while improvement for > 6 months was observed in all patients in Group 2. There was a statistically significant direct correlation between platelet count and levels of TNF- and IFN-gamma in both study groups, while a non-significant correlation was seen in Group 3. Thus, H. pylori infection should be considered in the differential diagnosis of all cases of thrombocytopenia, and should be eradicated in all H. pylori-positive patients with thrombocytopenia.

Abstract
This study was designed to estimate interferon-gamma (INF-gamma) levels among polytransfused haematology cases. Cases were selected from the haematology unit of Alexandria main university hospital, Egypt. Complete blood counts, estimation of INF-gamma and hepatitis B and C virus (HBV and HCV) status were conducted on 20 unsplenectomized patients with gamma-thalassaemia major and 20 patients with acute myeloid leukaemia (AML) in the maintenance phase and 20 healthy subjects. Mean haemoglobin levels and red blood cell counts were significantly higher in the control group than the AML and thalassaemia groups, while white blood cell counts were significantly lower in the control group than the case groups. Two AML patients (10%) and 1 thalassaemia patient (5%) were HBV-positive, while 5% of both case groups were HCV-positive. Mean values of INF-gamma were significantly different between AML, thalassaemia major and control groups: 5517 (SD 1142) pg/mL, 1024 (SD 249) pg/mL and 2980 (SD 604) pg/mL respectively.

Abstract
The role of inflammatory cytokines in the pathophysiology of beta-thalassaemia is still unclear. In this study production levels of interleukins (IL)-12 and IL-13 were measured by commercial ELISA in culture supernatants of mitogen-stimulated peripheral blood mononuclear cells-from 30 non-splenectomized beta-thalassaemia cases with iron overload and 20 age- and sex-matched healthy individuals. IL-12 levels were significantly lower among cases compared with controls (91.4 pg/mL versus 154.6 pg/mL), while IL-13 levels were significantly higher (42.5 pg/mL versus 5.7 pg/mL). There was a significant negative correlation between IL-12 and lL-13 levels among beta-thalassaemia cases (r= -0.42). Patients with beta-thalassaemia alone had higher IL-12 levels than beta-thalassaemia patients who were seropositive for chronic hepatitis B or C virus infection (140 pg/mL versus 50 pg/mL); IL-13 levels were slightly lower (65 pg/mL versus 67 pg/mL). An imbalance in the IL-12/IL-13 axis may be relevant to the pathophysiology of beta-thalassaemia.
