Objectives: It has been documented that the administration of exogenous androgens to immature female rats produces polycystic ovaries. There is a substantial reduction of antioxidants in this condition, with an elevated risk of oxidative stress. The current research is intended to evaluate these effects and to assess the protection provided by aqueous garlic extract (AGE). Methods: An experimental study conducted at University of Health Sciences, Lahore. The data was collected over a period of one month. Fifty female prepubertal rats, 21 days of age, were divided into five groups, A, B, C, D and E. Group A served as control. Group B received testosterone propionate (TP) subcutaneous for 14 days and served as disease control. Group C received testosterone propionate (TP) subcutaneous for 14 days and concomitantly Aqueous garlic extract (AGE). Group D receive testosterone propionate (TP) subcutaneous for 14 days and Aqueous garlic extract (AGE) from day 14-21. Group E received testosterone propionate (TP) subcutaneous for 14 days with no intervention till day 21. Blood samples of 50 female rats were drawn by doing cardiac puncture and clear serum was collected by centrifugation. This serum was used to assess the Catalase enzyme by using specific commercial kits. Results: The concentration and activity of catalase enzyme in the female rats with polycystic ovaries showed significant decrease as compare to the healthy controls. The involvement of antioxidants to manage the polycystic ovaries may be helpful as secondary therapy to prevent oxidative damage. Conclusion: The results showed that AGE with its antioxidative properties not only prevents the damage caused by oxidative stress, it also increased the level of serum catalase that helps to create a balance between beneficial oxidant generation and damaging oxidative stress. Key words: Androgens, immature female rats, ovaries, antioxidants, oxidative stress, aqueous garlic extract (AGE), Catalase. How to cite: Bashir.Y., Habib N. Ashraf .S.

SUMMARY Immature female rats were fed thiouracil for 30 days and injected with 10 i.u. human chorionic gonadotrophin (HCG) for the last 20 days. In thiouracil-fed animals, HCG produced large ovaries containing follicular cysts. These ovaries showed a subnormal concentration of cholesterol but both a normal total content and normal incorporation of [1-14C]acetate into digitonin-precipitable-sterols. Liver and serum cholesterol concentrations were reduced, but in vivo, 4 hr. incorporation of acetate into sterols was doubled suggesting either an acceleration of cholesterol turnover or delayed utilization of sterol precursors of cholesterol. HCG also reduced ovarian cholesterol concentration in euthyroid animals but total organ content and incorporation of [14C]acetate were not altered, nor were liver and serum cholesterol affected. Since the effect of induced ovarian cysts on sterol metabolism cannot be accounted for by known effects of thyroid or gonadal hormones it is suggested that influences of steroid hormones on lipid metabolism may be greatly modified in thyroid deficiency.

Doxorubicin (DOX) is effective chemotherapy in several malignancies, but large-scale toxicities limit its clinical usefulness. Propolis has been reported to exhibit a broad spectrum of biological activities. We aim to assess the protective efficacy of propolis against DOX-induced multi-toxicity in female rats. Forty female rats were divided into four groups: control group; Group (P) were administrated oral propolis (100 mg/kg once daily for 28 days); Group (P+DOX) were injected with a single intraperitoneal dose of DOX (20 mg/kg i.p at 24th day after the propolis administration) and group (DOX) were injected with doxorubicin only. Estimation of cardiac, renal and hepatic injury markers, apoptosis and pro-inflammatory cytokines were done using sera. Also, liver and heart tissue samples were collected to determine GSH and MDA as oxidative stress markers. In addition to histopathological and immunohistochemical examination of Cytochrome-C and Connexin43 on lysed myocardium, liver, kidney and lung tissues. Doxorubicin toxicity caused marked deteriorations of measured parameters through the different mechanisms in different body organs. However, pre-treatment with propolis significantly ameliorated these alterations. Thus propolis can ameliorate the DOX-induced experimental multi-toxicity as cardiomyopathy, hepatotoxicity, nephritis and pneumonia. Thus, it could be a promising protective agent in DOX treatment protocols.

Cadmium (Cd) has been recognised as one of the most important environmental and industrial pollutants, and up-to-date investigations have shown that one of the mechanisms of its toxicity is associated with the induction of oxidative stress. The aim of this study was to determine the connection between acute oral and intraperitoneal exposure to Cd and parameters indicative of oxidative stress in the plasma of rats, as well as to examine the potential protective effect of magnesium (Mg) in conditions of acute oral and intraperitoneal Cd poisoning. The experiment was performed on male albino Wistar rats (n=40) randomly divided into control group, Cdor group that received 30 mg kg-1 b.w. Cd by oral gavage, Cd+Mgor group that orally received 50 mg kg-1 b.w. Mg one hour before oral Cd, Cdip group that received 1.5 mg kg-1 b.w. Cd intraperitoneally, and Cd+Mgip group that intraperitoneally received 3 mg kg-1 b.w. Mg 10 min before intraperitoneal Cd. The animals were sacrifi ced 24 h after treatment and the following parameters were measured: superoxidedismutase activity, superoxide anion, total oxidative status, advanced oxidation protein products, and malondialdehyde. All parameters of oxidative stress in rat plasma were negatively affected by Cd treatment with more pronounced negative effects after intraperitoneal treatment, with the exception of superoxide dismutase (SOD) activity. Although both oral and intraperitoneal Mg pretreatment had protective effects, more pronounced benefi cial effects were observed after oral administration, since it managed to completely prevent Cd-induced changes in the investigated parameters. The observed results support the use of Mg as potential protective agent against toxic effects caused by Cd.

Toxoplasmosis is a common parasitic infection in the world. Since increased free radicals and oxidative stress are reported in many parasitic diseases the purpose of the present study was to evaluate the oxidative stress in acute and chronic toxoplasmosis. RH strains ofToxoplasmatachyzoites were used in the present study. Twenty-five female rats were infected with the parasite while 25 other rats were as the control group that received normal saline. Zero-, 5-, 7-, 10-, and 45-day postinfection (DPI) blood samples were taken. Some parameters related to oxidant and antioxidants such as antioxidant enzymes, malondialdehyde, and total antioxidant capacity were measured. On day 7 after infection, GPX activity and GSH level were significantly increased and in the mentioned day the amount of total antioxidant capacity was significantly reduced. In other cases, there were no significant differences between the groups in different days. Overall, based on the results it seems that, on day 7 after infection, in infected rats responses to oxidative stress were triggered and led to decrease of total antioxidant capacity. Furthermore, glutathione was increased to cope with stress. It seems that probably antioxidant defense system entered the infection to the chronic phase and changed the parasites stage.

Гипертиреоз - одна из частых причин вторичного остеопороза. Изучение темпов потери костной ткани при гипертиреозе (тиреотоксикозе) в различных возрастных группах является важным и мало изученным процессом. Цель работы - изучение влияния длительного введения высоких доз L-тироксина на показатели минеральной плотности костной ткани самок-крыс в различные возрастные периоды. Методика. Исследование выполнено на 50 самках крыс Wistar 2 мес., 5-6 мес. и 24 мес. L-тироксин (25 мкг на 100 г) вводили внутримышечно в течение 30 сут. Животные были разделены на группы: неполовозрелые самки (контроль), неполовозрелые самки, получавшие L-тироксин; самки репродуктивного возраста (контроль), самки репродуктивного возраста, получавшие L-тироксин; старые самки (контроль), старые самки, получавшие L-тироксин. Прижизненное определение показателей минеральной плотности костной ткани (МПКТ) проводили на двухфотонном рентгеновском денситометре «Prodigy» (GE Mediсal systems, LUNAR, model 8743, 2005; USA; программа «Experimental animals») дважды (в начале эксперимента и через 30 сут.). Исследовали позвоночник, кости таза, задние конечности и показатель МПКТ всего скелета. Результаты. Установлено, что введение высоких доз L-тироксина статистически значимо увеличивает показатели МПКТ во всех отделах скелета только у неполовозрелых животных. У крыс репродуктивного возраста введение высоких доз L-тироксина вызывало снижение показателя МПКТ, при этом максимальная потеря костной ткани была выявлена на уровне позвоночника и задних конечностей. Снижение показателя МПКТ было статистически значимым не только по сравнению с соответствующим показателем контрольной группы, но и по сравнению с исходными значениями. У старых крыс гипертиреоз вызывал менее значимое повышение МПКТ. Заключение. Выявленные возрастные особенности динамики показателей МПКТ следует учитывать при интерпретации данных рентгеновской денситометрии, в частности при изучении экспериментального вторичного остеопороза вследствие тиреотоксикоза. Hyperthyroidism is one of the common causes of secondary osteoporosis in patients of different ages, so the study of the rate of bone loss in different age groups is very important and little studied. The purpose was to study the effect of prolonged administration of high doses of L-thyroxin on bone mineral density (BMD) parameters of different regions of the skeleton of Wistar female rats at different age periods. Methods. The study was performed on 50 female Wistar rats of three age groups (2 months, 5-6 months and 24 months). L-thyroxin in a dose of 25 mcg per 100 g of body weight, was administered intramuscularly for 30 days. The animals were divided into the following groups: immature females of the control group; Immature female rats who received L-thyroxine; rats of the reproductive age of the control group; rats of reproductive age who received L-thyroxine; Old females of the control group; Old females who received L-thyroxine. In-vivo determination of BMD parameters was performed on a two-photon x-ray densitometer «Prodigy» (GE Medial Systems, LUNAR, model 8743, 2005, USA, Experimental animals program) twice (at the beginning of the experiment and after 30 days). The following sections of the skeleton were examined: the spine, pelvic bones, hind limbs and the BMD index of the entire skeleton. Results. It was found that high doses of L-thyroxine significantly increases BMD indices in all parts of the skeleton only in immature female rats. High doses of L-thyroxine to the animals of reproductive age caused declines in BMD, maximum bone loss was detected at the level of the spine and hind limbs. The decline in BMD was statistically significant, not only in comparison with the corresponding index of the control group, but also in comparison with the baseline values. In old rats the hyperthyroidism caused less significant increase in BMD. Conclusion. Identified age features of the dynamics of BMD indices should be considered in the interpretation of X-ray densitometry data, in particular in the studies of the experimental secondary osteoporosis due to hyperthyroidism.

In this study, it is aimed to determine the histopathological and haematological effects of apigenin, phloretin and myricetin on Wistar immature female rats using Tier 2 of the uterotrophic assay. The female rats were divided into 17 groups with 6 rats in each group. There was a negative control group and positive control dose groups that contained 0.07 µg/kg/day, 0.7 µg/kg/day and 7 µg/kg/day of ethinyl estradiol (EE), 0.7 µg/kg/day 17α-ethinyl estradiol + 1 mg/kg/day tamoxifen and genistein. The other dose groups contain 1 mg/kg/day, 10 mg/kg/day and 100 mg/kg/day of apigenin, myricetin and phloretin. All chemicals had been given to Wistar immature female rats with oral gavage for three consecutive days. At the end of the study, blood samples were analysed for haematological parameters. Tissue samples that were taken from the liver, kidney, spleen and thyroid were histopathologically and histomorphometrically examined. There were no significant differences between oil control and other dose groups for glomerular histomorphometry. However, there were siginificant differences for thyroid histomorphometry. Especially, 10 and 100 mg/kg/day of phloretin dose groups had a siginificant increase in colloid surface area in thyroid compared with the 1 mg/kg/day of phloretin and oil control groups. Significant histopathological changes (congestion, degeneration, fibrosis and mononuclear cell infiltration) were noted in the tissue specimens obtained from the treatment groups compared with the control group. According to the results of the haematological analysis of the groups, especially the values of erythrocytes and haematocrit were increased significantly in most of the dose groups according to the oil control group.

Backgound: The generation of oxidative stress can be referred to Aluminium toxic effect in animals and humans. This study aimed to evaluate the role of broccoli (Br) and beetroot (Be) extarcts as antioxidant that prevents oxidative stress that associated with aluminum toxicity. Materials and Methods: Fifty Wister female rats were grouped into five groups (each 10 rats): Group 1: control group, administered drinking water only. Group 2: (Neurogenerative) which were induced by oral administration of aluminum chloride (20 mg/kg b.w) daily for one month. Group 3: Rats given aluminum chloride were treated with Rivastigmine (Ri) (1 mg/kg b.w) as a reference drug daily for five weeks. Group 4: Rats given aluminum chloride were treated with beet root extract (50 mg/kg b.w) daily for six weeks. Group 5. Rats given aluminum chloride were treated with broccoli extract (50 mg/kg b.w) daily for five weeks. Results: (AlCl3) group showed a significant increase in Ach level (P<0.05) and a non-significant change in DOP and NE levels compared to control. (AlCl3+Be) was non-significant (P˂0.05) change in Ach, DOP and NE levels compared to (AlCl3) group and showed a significant (P<0.05) increase in Ach level compared to control. (AlCl3+Br) showed a significant (P<0.05) increase in NE level and non-significant (P˂0.05) change in Ach and DOP levels compared to (AlCl3) group. (AlCl3+Ri) showed a significant (P<0.05) increase in Ach, DOP and NE levels compared to (AlCl3) group. Also, showed a significant (P<0.05) increase in Ach and NE compared to control. Conclusion: Neuroprotective role of broccoli in the present study which may result from its antioxidant properties due to its bioactive content such as glucosinolate, isothiocyanate, Sulforaphane, and flavonoids. Therefore, Broccoli can have a favorable effect on neurotoxicity due to their antioxidant and anti-inflammatory properties.

Introduction: Cisplatin is one of the most widely used drugs for the treatment of various cancers but has oxidative tissue damage as one of its side effects. This study investigated the oxidative stress profile in some important body tissues following the co-administration of cisplatin (CIS) and resveratrol (RSV). Methods: Thirty-five adult female rats with an average body weight of 162g were divided into 5 groups (n=7) and used for this experimental study. Group A served as the normal control group and received distilled water only. Group B received only a single dose intraperitoneal injection of 10mg/kg CIS. Groups C, D and E were orally given 5, 10 and 20mg/kg of RSV respectively for 7 days, starting 24h after a single CIS dose intraperitoneal injection of 10mg/kg. Selected body tissues were harvested for oxidative stress profiling at the end of the experiment. Results: CIS significantly increased malondialdehyde levels and decreased glutathione, superoxide dismutase and catalase levels in all the tissues assessed (ovary, uterus, liver, kidney, pancreas, stomach and spleen) when compared to the normal control. The RSV treatment caused the reversal of these effects; malondialdehyde levels were significantly decreased, while glutathione, superoxide dismutase and catalase levels were significantly increased across all the examined tissues. Conclusion: RSV at different doses could be effective in the management of CIS-induced oxidative stress and lipid peroxidation across some body tissues. However, this effect may be dependent on the dose of CIS and RSV.
