تضمنت الدراسة الحالية معرفة بعض التاثيرات الفسلجية والكيموحيوية للمستخلصات المائية للكرفس (Apium graveolensL) والجرجير(Eruca sativa Mill) والطماطم (Lycopersicon esculentum Mill) في الدم والجهاز التناسلي لذكور الجرذان البيض المعرضة للاجهاد التاكسدي المستحد | The aim of the present study was to investigate some physiological and biochemical effects of the aqueous extract of celery (Apium graveolens L.), gardeen rocket (Eruca sativa Mill) and tomato frait (Lycopersicon esculentum Mill) on blood and male reproductive so system of Albino rats (Rattus norvegicus) exposed to oxidative stress induced by hydrogen peroxide 0.5% with drinking water for 21 days using vitamin E, as well known antioxidant as criterion for comparison. For the purpose of this study, preliminary experiments were carried out to find the most effective doses of plant extracts and it was found that these doses were 100, 150, 250 mg/kg body weight for, tomato, celery and gordeen roket extracts respectively. Fifty rats (12 - 14 weeks age) were randomly divided to ten groups (treatments) each with five replicates.These groups are : Group (1) (control group) : Rats without any treatment.Group (2) : Rats treated with H2O2.Group (3) : Rats treated with celery extract (150 mg/kg b.w.).Group (4) : Rats treated with celery extract (150 mg/kg b.w.) and H2O2.Group (5) : Rats treated with Eruca extract (250 mg/kg b.w.).Group (6) : Rats treated with Eruca extract (250 mg/kg b.w.) and H2O2.Group (7) : Rats treated with tomato extract (100 mg/kg b.w.)Group (8) : Rats treated with tomato extract (100 mg/kg b.w.) and H2O2.Group (9) : Rats treated with vitamin E (500 mg/kg b.w.).Group (10) : Rats treated with vitamin E (500 mg/kg b.w.) and H2O2 Results could be summarized as follow : 1. Compared with the control, the oxidative stress induced by H2O2 caused significant increase in total count of leukocytes, neutrophilis, acidophils, basophilis, monocytes and lymphocytes, and in the level of blood sugar (glucose), Total cholesterol, triglycerides(TG), low density lipoprotein (LDL - C), very low density lipoprotein (VLDL - C) atherogenic index (First and second), Urea, Malondialdehyde (MDA) and percentages of dead sperms and abnormal sperms.This stress showed as well, a significant decrease in body weight, Hb, PCV, high density lipoprotein (HDL - C), total protein, Albumin, glutathione, sperm total number, percentages of motile and normal sperms, testes weight, prostate and epididymis weights and seminiferous tubules diameter. This treatments, however, showed no significant variations in activity levels of ALT and AST enzymes and seminal vesicle weight.2. In comparison with treatment (2) (rats treated only with H2O2) , the treatment of rats, under oxidative stress with celery extract showed a significant decrease in total count of leukocytes neutrophils, lymphocytes and in blood suger, cholesterol TG atherogenic (First index) blood urea, MDA, Percentage of dead and abnormal sperms and seminal vesicle weight.This treatment showed also a significant increase in level of Hb, PCV., body weight, total protein, Albumin glutathione, number of sperm, percentages of motile and normal sperms, testis weight, epididymis weight and prostate weight. However no significant variations were detected in levels of acidophils, basophils, monocytes, HDL - C, atherogenic (second index) and seminituferous tubules diameter.3. Treatment of Eruca extract and compared with the treatment of H2O2, showed significant decrease in lymphocytes number and in the level of blood sugar, cholesterol (T.G), LDL - C, VLDL - C and atherogenic (first and second index) blood urea, MDA, percentage of dead and abnormal sperms and seminal vesicles weight. The treatment showed also a significant increase in body weight, numbers of acidophils, monocytes, basophils, HDL total sperm numbers, percentages of motil and normal sperms and weights of testis, epididymis and prostate.However, no significant variations were observed in Hb, PCV, Leukocyte total counts, neutrophil, albumin, ATL and AST and seminiferous tubule diameter.4. The treatment of tomato extract showed similar results to that of celary and Eruca extracts except, a significant increase in AST enzyme and seminiferous tubules diameter was detected in case of tomato extract (i.e not seen in case of other plant extracts).5. Compare with H2O2 treatment, rats under oxidative stress treated with vitamin E (500 mg/kg b.w) showed significant decrease in lymphocyte numbers, Total cholesterol, TG, LDL - C, VLDL - C, atherogenic (first and second index), urea, MDA and percentages of dead and abnormal sperms.At the same time the vitamin E treatment showed a significant increase in body weight , Hb, neutrophils, acidophils , monocytes, total protein, glutathione, total sperms number, percentage of motile and normal sperms, and weights of testis, epididymis, and prostate.However, this treatment (compared with H2O2 treatment) showed no significant difference in the level of PCV total count of leukocytes, basophils, blood sugar, HDL - C, albumin, ALT, AST, seminal vesicle weight and seminiferous tubules diameter 6. The most important histological changes exhibited by the animals under oxidative stress were apparent interstitial degeneration, necrosis of supporting and spermagonial cells, separation of these cells in semicyclic manner from the basement membrane, decrease in spermatids (spermatoblasts) and mature sperms in seminiferrous tubule cavity.These effects (due to H2O2 treatment) were decreased to minimal levels when the H2O2 treated rats exposed to plant extracts and vitamin E, used in this study.7. Animals treated with plant extract or vitamin E alone (i.e not treated before with H2O2) showed no clear difference from the control animal (without any treatment) though some improvement was observed in some physiological, biochemical and histological characters of blood and male reproductive system of the studied animals The above results revealed that the plant extract used in this study play an important role in decreasing the harmful effect of the free radicals in the animals (rats) studied.
