Objectives: To investigate the tissue-protective effects of three gel formulations (chitosan, chitosan with taurine or chitosan with dexpanthenol) as active substances against an acute overdose of diclofenac sodium. Methods: White outbred conventional male rats were allocated to five experimental groups: the first is an intact group that did not receive any drug, the second group is a control group that received 50mg/kg of diclofenac sodium once orally, the third, fourth and fifth groups are an experimental group that received our studied drugs at a dose of 0.16ml/100mg b.w. once orally 1 hr. before diclofenac sodium, the third group received chitosan-based gel 1%, the fourth group received chitosan-based gel 1% with 4% taurine and the fifth group chitosan-based gel 1% with 0.43% dexpanthenol. Blood samples were taken for biochemical, hematological and blood coagulation system tests on day 7th after administration of diclofenac sodium. Results: An acute overdose of diclofenac sodium caused marked extensive tissue necrosis in the liver, bleeding in the gastrointestinal tract and inflammatory process, these marks were evidenced by different changes in the test of the blood samples. Significantly 73.6% of the blood indicators were improved by the administration of chitosan-based gel 1% with 0.43% dexpanthenol, while 57.8% were improved by chitosan-based gel 1% with 4% taurine and 68.4% by chitosan-based gel 1%. Conclusion: Chitosan-based gel 1% with dexpanthenol 0.43% can help in mitigating hepatic injury, gastrointestinal bleeding, and systemic and local intestinal inflammation caused by an acute overdose of diclofenac sodium.

This study investigated the protective effects of vanillin against acute brain damage induced by carbon tetrachloride (CCl4) in rats. The study was performed on 32 male rats divided into four groups: a control group, vanillin group ([Va] 150 mg/kg/day, intraperitoneally [i.p.]) and CCl4 toxication groups received a single injection of CCl4 (1 ml/kg, i.p.; CCl4 and Va + CCl4 groups). The degree of protection in brain tissue was evaluated by the levels of malondialdehyde (MDA), glutathione (GSH), superoxide dismutase, glutathione transferase, glutathione peroxidase and nitric oxide (NO). Vanillin showed a significant brain-protective effect by decreasing the level of lipid peroxidation and NO2 and elevated the activities of antioxidative enzymes and level of GSH. Consequently vanillin blocked oxidative brain damage induced by CCl4 in rats.

Objective. The aim of this study was to investigate protective effects of resveratrol, a strong antioxidant, against possible negative effects of chronic immobilization stress on testes of male rats histochemically, immunohistochemically, ultrastructurally, and biochemically. Material and Methods. Male Wistar rats were divided into 4 groups (n=7). Group I, control group (C), was not exposed to stress. Group II, stress group (S), was exposed to chronic immobilization stress. In Group III, low dose resveratrol + stress group (LRS), rats were given 10 mg/kg/day resveratrol just before the stress application. In Group IV, high dose resveratrol + stress group (HRS), rats were given 20 mg/kg/day resveratrol just before the stress application. For chronic immobilization stress application animals were put in the plastic tubes (6 cm in diameter, 15 cm in length) during 32 days for 6 hours. All animals were sacrificed 18 hours after the last stress application. Results. Histochemical and ultrastructural investigations showed that in stress group there was germ cell deprivation in seminiferous tubules and increase of connective tissue on interstitial area. No significant changes were seen in low and high dose resveratrol groups. After immunohistochemical investigations, TUNEL (+) and Active Caspase-3 (+) cells were increased in seminiferous tubules of stress group compared with those control group, but they were decreased in low and high dose resveratrol groups. According to biochemically results, MDA, GSH, and testosterone levels in stress group showed no significant difference when compared with those of the other groups. Conclusion. The chronic immobilization stress increases oxidative stress and apoptosis and causes histological tissue damages; resveratrol can minimize the histological damage in testes significantly.

AbstractNicotine is one of the psychostimulant agents displaying parasympathomimetic activity; the chronic neurochemical and behavioral effects of nicotine remain unclear. Exercise lowers stress and anxiety and can act as a non-pharmacologic neuroprotective agent. In this study, the protective effects of exercise in nicotine withdrawal syndrome-induced anxiety, depression, and cognition impairment were investigated.Seventy adult male rats were divided randomly into five groups. Group 1 served as negative control and received normal saline (0.2 mL/rat, i.p.) for 30 days, whereas group 2 (as positive control) received nicotine (6 mg/kg/day, s.c.) for the first 15 days. Groups 4, 5, and 6 were treated with nicotine (6 mg/kg/day, s.c.) for the first 15 days and then were treated with forced exercise, bupropion (20 mg/kg/day, i.p.), or a combination of the two for the following 15 days. Between day 25 and day 30, Morris water maze was used to evaluate spatial learning and memory. From days 31 to 35, the elevated plus maze (EPM), open field test (OFT), forced swim test (FST), and tail suspension test (TST) were used to investigate the level of anxiety and depression in the subjects.Nicotine-dependent animals indicated a reflective depression and anxiety in a dose-dependent manner in FST, EPM, and TST, which were significantly different from the control group and also can significantly attenuate the motor activity and anxiety in OFT.Forced exercise, bupropion, or their combination can attenuate nicotine cessation-induced anxiety, depression, and motor activity in the mentioned behavioral assay. We conclude that forced exercise can protect the brain against nicotine withdrawal-induced anxiety, depression, and cognitive alteration.

Doxorubicin (DOX) is one of the most potent and widely used chemotherapeutic agents to treat several malignancies. However, the clinical use of DOX is seriously restricted due to its acute and chronic cardiotoxic side effects This study investigated the protective effect of (Ajwa) date aqueous extract (AJDAE) against doxorubicin-induced cardiotoxicity in rats. Sixty Wister albino male rats (150-200 gms.) were comprised in our study and divided into six equal groups: group I (untreated control), group II, group III, rats were orally received AJDAE (0.75 & 1.5 gm/ kg.bw) respectively, for 4 weeks, rats of groups IV, V and VI were intraperitoneally injected with one dose of doxorubicin (5 mg/kg.bw) at the end of the 4th week of the study to induce cardiotoxicity, rats of groups V & VI were orally received AJDAE (0.75 & 1.5 gm/ kg.bw) respectively. Cardiac enzymes, lipid profile, SOD, GR, GST, GPx, CAT and MDA in rats’ hearts homogenate, urinary 8OHdG as well as DNA integrity and histopathological changes were investigated in all studied rats.Oral administration of AJDAE (0.75 & 1.5 gm/ kg.bw) attenuated the cardiotoxicity of DOX, improved the cardiac enzymes, lipid profile, reduced the urinary 8OHdG and prohibited the depletion of endogenous antioxidants and suppressed lipid peroxidation (MDA). Moreover, AJDAE enhanced DNA integrity. Histological findings showed that AJDAE (0.75 & 1.5 gm/ kg.bw) administration reduced cardiomyocytes alterations, congestion, edema and the intense cellular stress exerted on myocardial fibers as well as restored the cardiomyocytes architecture. Our data showed that AJDAE obviously resulted in protective effects against DOX-induced cardiotoxicity in rat’s heart. It can be concluded that Ajwa date offers a considerable protection against DOX-induced cardiotoxicity.

Objective: We aimed to investigate whether cyclophosphamide-induced damage to rat ovary can be prevented by DHEA. Material and Method: Group 1 (the control Group): no treatment was administered. Intact ovarian tissue was removed and blood samples were taken for anti-mullerian hormone (AMH) test. Group 2 (the Cyclophosphamide Group): Rats received Cyclophosphamide intraperitoneally at a single dose of 150 mg / kg. Group 3 (the Cyclophosphamide + DHEA Group): Rats received Cyclophosphamide intraperitoneally at a single dose of 150 mg / kg at baseline and DHEA subcutaneously for 10 days at a dose of 60 mg / kg daily. Rats in groups 2 and 3 were sacrificed at the end of 10 days, ovarian tissues were removed and blood samples were taken for AMH test. Results: While normal ovarian tissue damage scores were zero, cyclophosphamide showed significant damage and histopathological changes in all rats. Cyclophosphamide group had higher vascular congestion (p=0.004) and total damage scores (p=0.010) than normal ovarian group. Cyclophosphamide + DHEA group had higher edema (p<0.001), vascular congestion (p<0.001) and total damage scores (p<0.001). Cyclophosphamide group had a decrease in primordial (p = 0.001), primary (p = 0.043) and preantral follicles(p = 0.006). Cyclophosphamide + DHEA group showed a decrease in primordial (p = 0.001) and antral follicles(p = 0.018). AMH levels did not decrease in both groups. Conclusions: It was found that the use of DHEA to prevent Cyclophosphamide-induced ovarian damage in rats did not produce significant changes in antral follicle counts, ovarian volume, and AMH levels, which were important for clinical practice.

Infertility in marriage is an important medical, biological, social and demographic problem. Inguinal hernioplasty is objectively considered as a factor of male infertility in 9.8% of cases. Under these pathological conditions, the structural elements of the spermatic cord are compressed those appears the circulatory disturbances in testicle. Disorders of reproductive function often occur precisely because of hemodynamic disorders, which are considered one of the leading pathogenetic factors in the development of male infertility. Purpose — to establish peculiarities of testicles vessels and tissues remodeling under dosed spermatic cord stenosis conditions and during the reperfusion period. The experiments have been carried out on 78 non-linear white male rats, weighting 180–200 grams which were fed due to a standard diet of vivarium. All the animals were divided into four groups: one control group and three experimental ones. The control group included six intact animals. All the other comprised the experimental group which was divided into three series six animals per each depending on the terms of observation. The animals with the model of dosed stenosis of funiculus comprised first experimental group; the animals with the model of dosed stenosis and one-moment decompression, starting from the third day of the experiment comprised the second group; to the third group we referred the animals with the model of dosed stenosis of the funiculus which have undergone decompression with the correction of reperfusion changes due to the method proposed by us, starting from the third day. During the experiment it was established that after one-time decompression of the spermatic cord that was under the experimental stenosis conditions, apereas destructive changes in testicles parenchyma and decreases the functional activity of the organ. Despite that the compression factor has been removed and the blood flow in arteries and veins has been fully restored, there was no improvement in the hemodynamics of the testicle. The use of the dosage decompression method of the spermatic cord helps to improve the hemodynamic conditions of the organ during the reperfusion period. In this case, the detected changes of the testicle’s parenchyma and its intra-organ vessels were less pronounced than during stenosis of the spermatic cord and its one-time decompression. The functional activity of the testicles with use of the reperfusion changes correction, was slightly violated, the spermatogenesis index has been increased and the mature forms of spermatozoa were present in the seminiferous tubules. Thus, the usage of the proposed method of the spermatic cord decompression allows us to obtain positive dynamics in testicles blood vessels remodeling in reperfusion period.

The aim of this study is to assess the effects of high blood glucose levels in male rats with diabetic induced by alloxan on their physiological conditions. Diabetes mellitus is a category of metabolic hyperglycemia disorders caused by insufficient body production or pancreatic action. In addition to hyperglycemia, a number of other factors are also important for pathogenesis, such as Hyperlipidemics and cortisol oxidative. Forty five mature male rats used in this study, these were divided into 3 groups, Control group(G1) : gavage distilled water, Group2(G2): injection intraperitoneally with Alloxan150 mg/kg bw for two weeks and Group3(G3): injection intraperitoneally with Alloxan 150mg/kg bw for twenty four days. Blood samples taken from all groups estimation of Peroxynitrate, GSH, CAT, and SOD concentrations%. The findings revealed a significant improvement in diabetic classes in glucose (p<0.05) and peroxynitrate relative to control (G1). Diabetic concentrations of (G2, G3) relative to the control group (G1) were substantially reduced in SOD, GSH, CAT and diabetes mediated (P < 0,05). In conclusion, diabetes can cause significant changes in SOD, GSH, CAT levels in rats.

Цель исследования - оценка возможности использования интегральных гематологических индексов для выбора оптимальной модели ушивания послеоперационных ран в эксперименте. Методика. Исследование проводили на 297 белых беспородных крысах-самцах массой 190-210 г, которые были разделены на 3 группы, по 99 крыс в каждой. Одна группа являлась контрольной, у второй группы крыс был смоделирован раневой процесс с натяжением брюшной стенки; у третьей группы животных - модель раневого процесса с применением трансплантата нанокомпозитного материала. Определяли следующие интегральные гематологические индексы: индекс Кребса; коэффициент Бредекка; лейкоцитарный индекс; индекс соотношения нейтрофилов и моноцитов; индекс соотношения лимфоцитов и моноцитов; индекс соотношения лимфоцитов и эозинофилов; коэффициент отношения альбуминов к глобулинам; оксипролиновый коэффициент. Результаты. Установлены статистически значимые колебания показателей интегральных гематологических индексов в динамике заживления послеоперационной раны у крыс. Заключение. На основе полученных результатов был сделан вывод, что особенности динамики интегральных гематологических индексов, выявленные на различных моделях раневого процесса, отражают неспецифические и специфические защитные реакции организма в целом, позволяют делать прогноз дальнейшего течения и исхода раневого процесса, а также обеспечивают возможность выбора оптимальной модели ушивания послеоперационной раны. The article presents results of predicting the wound healing process using integral hematological indexes. The aim of the study was to describe the dynamics of integral hematological indexes of wound healing process in rats to predict its outcome. The study included 297 white mongrel male rats weighing 190-210 g, which were divided into three groups, 99 rats in each. One group was a control group; in the second group, a wound healing process with abdominal wall tension was modeled; in the third group, a wound healing process with a graft was modeled. The following integrated hematological indexes were determined: Krebs index; Bredeck index; leukocyte index; neutrophil/monocyte ratio; lymphocyte/monocyte ratio; lymphocyte/eosinophil ratio; albumin/globulin ratio; and oxyproline coefficient. The study showed that changes in values of integral hematological indexes were mostly statistically and clinically significant. We concluded that changes in integral hematological indexes in different models of wound healing reflect nonspecific and specific protective responses of the body as a whole and allow to predict further course and outcome of the wound healing process.
