تاثير عصارة نبات البروكلي في متلازمة تعدد الاكياس المبيضية المستحدثة في الجرذ الابيض Effect of Broccoli Plant Juice On Induced Polycystic Ovarian Syndrome In Albino Rats

المستخلص: The goal of present study was to investigate the benefits of broccoli as anti androgenic plant in protection and treatment for reproductive hormonal and metabolic disturbance, which combined with polycystic ovarian syndrome (PCOS). Three experiments for 3 PCOS models were done. First Experiment : The prepubertal female rats at 21 days old, were injected with Testosterone (T) subcutaneously for 39 days (first model). The females of this experiment were divided into 6 groups (8 rats each) as follows : Group 1 was injected with sesame oil. Group 2 was injected with T hormone. Group 3 was injected with T hormone with orally gavaged of broccoli juice. Group 4 was injected with sesame oil, and at the end of the last injection was orally gavaged with distilled water for 30 days. Group 5 was injected with T hormone, and at the end of the last injection was orally gavaged with distilled water for 30 days. Group 6 was injected with T hormone, and at the end of the last injection was orally gavaged with broccoli juice for 30 days. Second Experiment : The prepubertal female rats at 21 days old, were injected with Letrozole (L) subcutaneously for 39 days (second model).The females of this experiment were divided into 6 groups with the same style of the first experiment. Third Experiment : it was achieved by the injection of pregnant rats prenatally (days 16 to 19 of gestation) with 1 mg of T hormone subcutaneously (third model), and then the female offspring were divided into groups (8 rats each) as follow : The first offspring group : The female rats offspring at 21 days old (their mothers were injected with sesame oil from 16th to 19th day of gestation) were orally gavaged with distilled water until 60 days of age. The second offspring group\ gavaged with distilled water : The female rats offspring at 21 days old (their mothers were injected with T hormone from 16th to 19th day of gestation) were orally gavaged with distilled water until 60 days of age. The second offspring group\ gavaged with broccoli juice : The female rats offspring at 21 days old (their mothers were injected with T hormone from 16th to 19th day of gestation) were orally gavaged with broccoli juice until 60 days of age. The third offspring group : The female rats offspring at 21 days old (their mothers were injected with T hormone from 16th to 19th day of gestation and orally gavaged with broccoli juice) were orally gavaged with distilled water until 60 days of age. Females of all groups were sacrificed after 24 hours from the last treatment to undertake weight, histological, hormonal and metabolic study for each group. the results of present study showed the symptoms that reported PCOS of the three female experiments such as ovarian cyst, hyperandrogenemia, hormonal and metabolic disturbance, etc. Also a well improvement has been noticed in all syndrome symptoms on females gavaged with broccoli juice for all three rats PCOS experiments, these results indicate that broccoli juice has got a protective and curative role against this syndrome.

تاثير الجسيمات النانوية للنحاس على بعض اعضاء الجهاز التكاثري الذكري للفئران البيض Mus musculus Effect of Copper Nanoparticles On Some Organs of Male Reproductive System In Albino Mice Mus Musculus

المستخلص: This study was conducted on 20 male of Swiss albino mice, where the main target of this study was to identify the influence of copper nanoparticles (Cu - NPs) on some organs of the male reproductive system. Animals were orally administered with 0.1 ml of 100 mg/kg Cu - NPs for 7, 14, 21 days. Then the animals were dissected in the next day after the end of the dosing period and took from them testes and epididymis (head and tail) to study the parameters in which these particles have affected, and this parameter as follows : 1 - Changes in the weights of each of the animals bodies, testes, tunica albuginea, and epididymis (heads and tails). 2 - Changes in sperm characteristics in testes and epididymis (head and tail), which included : the percentage of live sperms, abnormal sperms and sperm concentration. 3 - Changes in the percentages of the spermatogenic cells, which included : a - Spermatogonia. b - Primary & Secondary Spermatocytes. c - Spermatids. d - Sperms. 4 - Changes in numbers of leydig cells and nuclei diameters. 5 - Changes in diameters of seminiferous tubules and their lining wall thickness. 6 - Changes in thickness and height of epithelial cells in both the head and tail of the epididymis. 7 - Histopathological changes in testes and epididymis (head and tail). Phenotype description of testes from mice treated with copper nanoparticles for a period of 21 days occurrence of congestion and a few amount of fatty material around the testes. The results also revealed a decline in the average body weights on the period of 7 and 21 days of treatment when compared with the weight of the same animals before treatment and the decline was significantly at (P<0.05). Whereas the testes and tunica albuginea weights recorded a significant decrease in their average weights (P<0.05) when compared with control groups. As well as the epididymis weights where showed significantly decrease (P<0.05) in the average of the epididymides heads weights for all three periods of treatment, while a significant decrease (P<0.05) in the average weight of the epididymis tail appear for two periods 7 and 21 days compared with control groups. The study also reported a decrease in the percentage of live sperm and the average sperm concentration and an increase in the percentage of sperm abnormalities extended to all periods of treatment compared with control groups and this change was significant at the level of (P<0.05). The number of leydig cells and nuclei diameters, the results show a decrease in their averages and all the extended treatment period when compared with control groups, and this decrease was significantly at (P<0.05). Treatment with particles of copper nanoparticle indicated a decrease in the percentage of spermatogonia, primary spermatocytes and sperms in all periods of treatment compared with control groups and this decrease was significantly at the level of (P<0.05). While the results of the study revealed a significant increase at the level of (P<0.05) in the percentage of secondary spermatocytes and spermatids compared with the control animals. The study also showed a significant decrease at the level of (P<0.05) in the diameter of the seminiferous tubules of testes and the wall thickness of the seminiferous tubules for all periods of treatment compared with control groups. As well as a reduction in wall thickness and height of the epithelium in epididymis (head and tail) for all periods of treatment compared with control animals and this decline was significantly at (P<0.05). The current study also recorded a textile damage in the testes and epididymis (head and tail), which summarized the crash of some seminiferous tubules, degeneration of lining cells in tubule, the appearance of vacuole between cells and lifting epithelium from the basement membrane. On this basis, this study has shown for the first time that particles of copper nanoparticles have a negative impact on the effectiveness and activity of the male reproductive system in albino mice.

تاثير الدقائق النانوية للفضة في بعض الجوانب التركيبية والوظيفية للجهاز التناسلي الذكري للفئران Effect of Silver Nanoparticles On Some Structural And Functional Parameters of Male Reproductive System of Mice

المستخلص: تطرقت هذه الدراسة الى معرفة تاثير الدقائق النانوية للفضة (Ag NPs) في بعض الجوانب التركيبية والوظيفية للجهاز التناسلي الذكري للفئران. جرعت الحيوانات فمويا بالـ Ag NPs بجرعة 5 ملغم/مل وللمدد 5, 10, 15 يوما وفي اليوم التالي لانتهاء كل مدة معاملة تمت التضحية | This study touched to know the effect of silver nanoparticles (Ag NPs) on some organs of the reproductive system and the testosterone hormone in male albino mice. animals were orally dosed with 200 mg/kg of Ag NPs for 5, 10, 15 days and the next day to the end of each period of treatment has animal sacrificed and autopsy after taking their weights before and after the treatment for the comparison between them and then took the testes and epididymis (head and tail) from them after measuring their weights. This study included the study of changes in the weight of animals and organs, sperm characters in both the testes and epididymis, the percentage of cells generating sperm, the number of Leydig cells and the diameters of these cell nuclei, changes in the seminiferous tubules in the testes and changes in epididymis tubule and histopathological changes as well as changes in testosterone level. The results of the animals weights before treatment showed a significant decrease (P<0.05) compared to the weights of the same animals after treatment, while the results of this study after comparing with the control group showed a significant decrease (P<0.05) in the weights of testes and tunica albuginea for the periods of 5, 10 and 15 days. The epididymis showed a significant decrease (P<0.05) in the average weights of the epididymis head for the three periods while the average weights of the epididymis tail showed a significant decrease (P<0.05) for the periods of 10 and 15 days. The vitality and the concentration of the sperms showed a significant decrease (P<0.05) in their percentages for the three periods. All the results above showed a significant decrease (P<0.05) when they compared between the three periods of the treatment. While the sperm abnormalities showed a significant increase (P<0.05) in their percentage in each of the testes and epidydimes for the periods 5, 10, 15 days with a significant increase (P<0.05) in these abnormalities when they compared between the three periods of the treatment. The histological results of this study after comparing to the control group revealed histopathological changes in the testes and the epididymis (head and tail). The percentage of spermatogenesis showed a significant decrease (P<0.05) in the number of spermatogonia, primary spermatocyte and sperms when compared to the control group with a significant decrease in the number of these cells when compared the three treatment periods with each other. While the number of secondary spermatocyte and spermatids was significantly increased (P<0.05) when compared with the control, with a significant increase in the number of these cells when comparing the three periods of treatment. Whereas the results of Leydig cells after comparing to the control group showed a significant decrease (P<0.05) in the number and the diameter of the cell nucleus. The results of this study also showed a significant decrease (P<0.05) in the thickness and the diameter of the seminiferous tubules of the testes and the thickness, The epithelium height of the epididymis (head and tail) when compared to the control group with significantly decrease in the thickness and diameter of the seminiferous tubules of the testes and the thickness and epithelium height of the epididymis (head and tail) when they compared between the three treatment periods. The results of this study when compared to the control group showed a significant decrease (P<0.05) in the level of the testosterone hormone with significantly increase (P<0.05) in the testosterone level when compared between the periods of 5, 10, 15 days. From these findings it is concluded that the AgNps crossed the blood - testis barrier and caused many changes to the testicular tissues and decreased the level of the testosterone. This may affect the fertility of mice.
