Organophosphate insecticides (OPIs) including dimethoate are used in agriculture to control the insect pests, increasing the productivity, their frequent use has resulted in detrimental effects on biological systems and public health. This study aimed to evaluate the effect of dimethoate (DM) on fetuses, DNA concentration in ovarian tissues and levels of estradiol and progesterone in female mice. Methods. Female mice were divided into three groups: Group I, serve as control and was given distilled water intraperitoneally, while Group II and III were given (0.1- & 0.2-ml DM/100 ml distilled water) respectively for 7 days. Two treated females were housed with one untreated male for mating. After 7 days of the last dose, 6 female mice of each group were weighed and killed. The ovaries, uteri and liver were extracted and weighed, and ovarian hormones were measured. Also, DNA concentration in each ovary was determined. Results. The results showed a significant decrease in the weights of the liver and ovaries, the level of estradiol hormone, and DNA concentration in the ovary of treated mice as compared to those from the control group. Also, significant changes were observed in the weights of fetuses as well as the number of live fetuses. Conclusion. We found that administration of DM intraperitoneally to female mice for 7 days has influences on ovary weight, estradiol levels, and DNA concentration as well as its impact on the fetuses, therefore, it is better to use safer methods for control the pests and avoid increased use of pesticides.

Ciprofloxacin (CPFx) is one of a second-generation fluoroquinolones antibiotic and is prescribed a lot for curing bacterial infection. The aim of this study was to investigate of impact CPFx on sperm characteristics, liver DNA and histological structure of liver and testes. Twenty-four male mice aged 7-10 weeks were divided into three groups of eight. The first group (control) was given distilled water. The second and third groups received CPFx with doses 500 and 750 mg/kg respectively. All treatments were administrated orally for 14 days. Three untreated females were put with one treated male for mating. At the end of dosing period, mice were killed, testes and liver were removed and weighed. Sperm parameters, testosterone level and liver DNA were measured. Histopathology of liver and testes was carried out. The results showed that CPFx significantly affected liver DNA, sperm motility and morphology as well as it caused histopathological alterations of hepatic and testicular tissues. Moreover, it led to a significant elevation in the percentage of dead fetuses and also deformity fetuses. The results indicate that CPFX has detrimental effects on sperm quality, liver DNA and histological structure of testes and liver; therefore, it should be used with great caution.

Background and objectives. Herbal medicines have gained significant attention from the scientific community for treating and managing diabetes in both developing and developed countries. Boswellia serrata, known for its anti-inflammatory and antioxidant properties, has been historically used to treat various diseases. This study aimed to determine the effect of Boswellia serrata on body weight, blood glucose level, and pancreas architecture in alloxan-induced diabetes in albino mice. Methods. Forty albino male mice, aged 10 to 12 weeks and weighing between 24 and 34 grams, were divided into four groups of ten each. The first group was the negative control group, and the second group was the diabetic positive control group that received 120 mg/kg alloxan intraperitoneally. The third group received a single injection of alloxan at a dose of 120 mg/kg bw and was treated with Boswellia serrata macerated at a dose of 150 mg/kg bw for four weeks. The fourth group received orally Boswellia serrata extract at a dose of 150 mg/kg for two weeks, followed by a single injection of alloxan at a dose of 120 mg/kg, and were left for two weeks. Results. This study found that Boswellia serrata has antidiabetic properties in diabetic mice, as it significantly reduced blood sugar levels compared to the diabetic group. Additionally, histological analyses of the groups treated with B. serrata showed a significant improvement in the harmful effects of alloxan on pancreatic islet cells. Conclusion. Boswellia serrata has shown a notable improvement in the detrimental effect of alloxan on pancreatic islet cells, and its curative effect has been proven to be better than its prophylactic effect. This is supported by the improved blood glucose levels and the histological changes that were more pronounced.

Recently there has been an increased association between toxic substances present in the environment and male infertility. Carbon tetrachloride (CCL4) is widely used as a chemical intermediate and as a feedstock in the production of chlorofluorocarbons. CCL4 is highly toxic to the liver, kidney, testicle, brain and other tissues. Therefore, the present study was designed to identify its effect on the reproductive system in adult male mice. Thirty adult male albino mice were divided into three equal groups (n=10): the first group control, the second group received 0.1m/100g body weight olive oil and the third group received 0.1ml/100g/body weight CCL4 intraperitoneally every alternate day for three weeks. The results showed that CCl4 causes a significant decrease in body weight, sperm motility, sperm count and testosterone level, while it leads to a significant increase in the number of abnormal sperm morphology. Additionally, CCL4 caused apparent alterations in the histological structure of the testes. In conclusion, CCl4-induced reproductive toxicity in male mice.

Green Tea Extract, or GTE, is a powerful antioxidant that can be added to the extender to maintain the quality of Bali bull semen before and after freezing. This study aimed to evaluate the impact of the GTE addition in the extender on the sperm kinematic and sperm morphology from frozen semen of Bali bull. Five Bali bulls from the NAIC, were used as semen sources. In this study, there were four different treatments: a control (Tris-egg yolk without GTE), a GTE0.05 (100 mL tris egg yolk with 0.05 mg of GTE), a GTE0.10 (100 mL tris egg yolk with 0.10 mg of GTE), and a GTE0.15 (100 mL tris egg yolk with 0.15 mg of GTE). A sperm analyzer (CASA) was used to observe the sperm kinematics and morphology. Compared to the control group, adding different concentrations of GTE to the semen extender did not affect the sperm’s morphology. Before freezing, adding GTE0.05 increases total and progressive motility as well as VAP, VCL, and VSL after thawing. GTE0.15 increases STR and ALH. The conclusion is that GTE additions at doses of 0.05 mg/100 mL and 0.15 mg/100 mL can increase sperm kinematics parameters, but sperm morphology is not affected by the GTE.

Background: Lead impairs female reproductive health because it can induce oxidative stress. Zinc as an antioxidant produces an enzyme system that helps neutralize free radicals. α-Tocopherol has an antagonistic effect that reduces oxidative stress. This study aimed to demonstrate the effects of zinc (Zn) and α-tocopherol on the ovarian endogenous antioxidants and antral follicles of albino rats (Rattus norvegicus) exposed to lead acetate (Pb (C2H3O2)2). Methods: Twenty-five female Wistar rats were divided into five groups, namely groups K (control), P0, P1, P2, and P3. Following exposure and treatment for 21 days with different combinations, the albino rats were necropsied, and their ovaries were removed for subsequent histopathological preparations and endogenous antioxidant analysis. Observations were made on the ovary, including an antral follicle count and diameter calculations. Analysis of the superoxide dismutase (SOD) levels (560 nm wavelength) and malondialdehyde MDA-TBA (532 nm wavelength) were performed by a spectrophotometer. The data were analyzed using a oneway ANOVA and least significant difference (LSD) test with the SPSS V24 software. Results: The highest SOD enzyme expression in the albino rat ovaries was in P0 (17.23 ± 5.34), and the lowest was in P3 (4.21 ± 0.76). The lowest MDA level was observed in the control group (K) and P3 compared to the other groups. The highest average antral follicle count and diameter were found in the albino rats exposed to 1.5 mg/kg BW lead acetate, and treated with 0.54 mg/kg BW zinc sulfate and 100 mg/kg BW α-tocopherol (group P3) compared to the other groups. The mechanisms of action of zinc and α-tocopherol work synergistically to decrease free radicals and ovarian damage. Conclusion: The results showed that a combination of 0.54 mg/kg BW zinc (Zn) and 100 mg/kg BW α-tocopherol can maintain the number and diameter of the antral follicles and reduce ovarian SOD expression and MDA levels in albino rats exposed to lead acetate.
