RESUMO

Drug counseling is important in women with epilepsy since data about the effects of maternal antiepileptics on the developing fetus are limited. Although pregnant patients on the most teratogenic drugs are treated in accordance to the European Medicines Agency guidelines, a large amount of them may be exposed to the teratogenic medications unintentionally. We performed a tertiary center observational study about medications of pregnant women who were consulted to Teratology Information Service (TIS) unit for evidence-based teratogenic risk analysis. The registration records of 134 pregnant women between 2014 and 2018 were examined. We evaluated the diagnoses, prescriptions, usage of antiepileptic drugs, and distribution of drug subtypes and investigated the drug-related congenital anomalies after delivery. Women were recontacted after delivery to obtain information about health status of infants. We found that 33 women were diagnosed with neurological disorders. A total number of 60 neurologic drugs was prescribed, including 13 antiepileptics. Antiepileptic drugs covered 38.4% valproate (n = 5), 15.4% pregabalin/gabapentin (n = 2), 15.4% levetiracetam (n = 2), 15.4% lamotrigine (n = 2), 7.7% phenytoin (n = 1), and 7.7% carbamazepine (n = 1). Delivery outcomes revealed that valproate exposure resulted in one baby with congenital cataracts, one postnatal exitus with cardiac dysfunction, and one therapeutic abortion. Various antiepileptic drugs were prescribed to pregnant women prenatally or at different times of pregnancy and valproate was the most common antiepileptic drug consulted to TIS for teratogenic risk analysis. Disseminating TIS units and reporting the outcomes to the teratogenesis literature provide proper evaluation of teratogenic risks of drugs accordingly.

RESUMO

BACKGROUND: Doxorubicin is an anthracycline chemotherapeutic agent that causes cardiomyopathy as a side effect. Here, we aimed to investigate the effects of linagliptin and bisoprolol on the management of doxorubicin-induced cardiomyopathy in rats. METHODS: Wistar rats were divided into six groups (n = 8). Group I received saline for 4 weeks; group II received 1 mg/kg bisoprolol for 8 weeks; group III received 3 mg/kg linagliptin for 8 weeks; group IV received 1.25 mg/kg doxorubicin for 4 weeks for the induction of cardiomyopathy; group V received 1.25 mg/kg doxorubicin for 4 weeks plus 1 mg/kg bisoprolol for 8 weeks; and group VI received 1.25 mg/kg doxorubicin for 4 weeks plus 3 mg/kg linagliptin for 8 weeks. Electrocardiography and isometric mechanography were conducted to measure ventricular contractile responses. Myocardial tissue and serum samples were analyzed for oxidative and cardiotoxic markers by ELISA. RESULTS: Electrocardiography revealed that QRS, QT and Tp intervals were longer in group IV than group I. Doxorubicin caused a significant decrease in ventricular contraction, which was significantly prevented by bisoprolol. Doxorubicin resulted in myocardial fiber disorganization and disruption, but bisoprolol or linagliptin improved this myocardial damage. Glutathione peroxidase was significantly decreased in groups IV and V. Bisoprolol or linagliptin treatment attenuated the significant doxorubicin-mediated increase in malondialdehyde. Doxorubicin and linagliptin provided significant elevations in CK-MB activity and troponin-I levels. CONCLUSIONS: Doxorubicin resulted in pronounced oxidative stress. The beneficial effects of bisoprolol and linagliptin on myocardial functional, histopathological and biochemical changes could be related to the attenuation of oxidative load.

RESUMO

BACKGROUND: Reactive oxygen species-induced cell injury has been considered to be one of the main etiologic factors in ischemia-reperfusion injury (IRI). As a potential antioxidant agent, epigallocatechin gallate (EGCG) was examined in skeletal muscle of the rats after IRI with or without treatment. MATERIALS AND METHODS: Tourniquet application applied to the rats' hind limbs was selected as the appropriate IRI method. Animals were randomly distributed to one of the following groups: (1) sham control + SF (saline) (10 mg/kg/i.p.) (SC-SF), (2) IRI (4 + 2 h) + SF (10 mg/kg/i.p.) (IRI-SF), (3) IRI and EGCG (25 mg/kg/i.p.) (IRI-EG25), and (4) IRI and EGCG (50 mg/kg/i.p) (IRI-EG50). In another set of experiments with identical groups, the only difference was that the reperfusion period was 24 h. A number of different parameters relating to the damage seen in the skeletal muscles, lungs, kidneys, and liver and particular cytokines were measured by proper analytical methods. RESULTS: In comparison with the SC-SF group, IRI (4 + 2 h) induced an increase in the total oxidative status of skeletal muscle (10.17 ± 0.61 versus 15.74 ± 1.10) and blood creatine phosphokinase (CPK) (669.88 ± 50.23 versus 7202.38 ± 766.13) and lactate dehydrogenase levels (686.00 ± 67.48 versus 1343.00 ± 113.01). Although 25 mg/kg EGCG could not reverse these parameters to their normal levels, the higher dose of EGCG, that is, 50 mg/kg, was sufficient to prevent the increases seen in total oxidative status (8.55 ± 0.85) and CPK levels (4741.63 ± 339.40). In addition, reduced total antioxidant status of skeletal muscle in the IRI-SF group (0.50 ± 0.06) was elevated by the administration of EGCG (50 mg/kg) (0.85 ± 0.04). Regarding remote organ injury, only alanine transaminase (ALT) and aspartate transaminase (AST) levels were found to be increased, showing a slight damage in liver tissue. However, neither dose of EGCG was able to prevent this deleterious effect. As for cytokines (interleukin-1ß, IL-6, IL-8, tumor necrosis factor-α, and monocyte chemotactic protein-1), there were no differences between the study groups. In regard to long-term IRI (i.e., 4 + 24 h), statistically significantly elevated parameters in the IRI-SF group were as follows: CPK, lactate dehydrogenase, creatinine (Cr), and blood urea nitrogen. On the other hand, none of them were influenced by either dose of EGCG. According to the results, EGCG demonstrates a considerable protective effect toward IRI (4 + 2 h) of skeletal muscle. CONCLUSIONS: Although oxidative stress seems to play a significant role both in the pathogenesis of IRI and in the mechanism of action of EGCG, there is no evidence that inflammatory cytokines are, at least in our model, crucial mediators regarding the former events.

RESUMO

Isotretinoin is known as a potent teratogenic agent. Pregnancy should be ruled out before isotretinoin is prescribed. In this study, we evaluated the fetal outcomes of pregnant women who had inadvertently been exposed to isotretinoin during or before pregnancy. We collected data of pregnant women who had admitted to the Teratology Information Service due to isotretinoin exposure. Data regarding medications and comorbidities were documented. Outcomes were grouped as: live births, stillbirths, live births with congenital malformations, induced abortions (due to fetal abnormalities), spontaneous abortions, and elective abortions. We found that three women had gone to elective abortions. Three babies were live born without birth defects, of which, maternal exposure periods were between 0 and 3 weeks, 9 and 10 weeks before last menstrual period. One woman, exposed to isotretinoin up to the fourth week of gestation, decided ongoing her pregnancy with no current drug-related complications. Although many risk management programs worldwide have been used to prevent isotretinoin-related teratogenicity, the results of the present study showed that women became pregnant during isotretinoin intake and opted for pregnancy termination. Attention should be paid to the risk management programs mandating effective contraceptions, in order to lessen the drug-related terminations.

RESUMO

BACKGROUND: Pharmacovigilance and spontaneous reporting of adverse drug reactions (ADRs) have pivotal roles in drug safety. This study aimed to evaluate the knowledge, attitude and practice of health professionals towards pharmacovigilance in a university hospital in Turkey. METHODS: An observational, cross-sectional study via a 25-item self-administered questionnaire was conducted among physicians (n=161) and nurses (n=321). RESULTS: Although 66% (320/482) of the subjects were aware of the 'pharmacovigilance' term, the awareness of the Turkish Pharmacovigilance Center was as low as 30% (161/482). Similarly, 41% (198/482) of the subjects did not know the pharmacovigilance contact point of the hospital. Defining and determining new ADRs and improving patient safety were associated with the importance of spontaneous reporting by the subjects. According to the physicians, unawareness of the national pharmacovigilance system was the first discouraging factor, as was the unawareness of the need for spontaneous reporting of ADRs for the nurses. Although the frequency with which the nurses encountered ADRs was lower than that of the physicians, their claimed reporting ratio (21%; 68/321) was more than the physicians (8%; 12/161). CONCLUSIONS: There is significant potential under-reporting of ADRs, which seems to be the result of several factors, including the lack of the knowledge of the national pharmacovigilance system.

RESUMO

OBJECTIVE: Postmenopausal osteoporosis is a frequent cause of morbidity and can negatively impact life expectancy; iodine is an essential element for bone mineralization, and iodine deficiency is frequently observed. The aim of the present study was to understand the connection between postmenopausal osteoporosis and the level of iodine in the body. METHODS: A total of 132 participants were divided into three groups: group 1 consisted of healthy postmenopausal women (n = 34), group 2 comprised osteopenic women (n = 38), and group 3 included women with postmenopausal osteoporosis (n = 60). The three groups were compared according to demographic, clinical, and laboratory findings. RESULTS: The urinary iodine levels were recorded as 216.1 ±â€Š125.2 in the control group, 154.6 ±â€Š76.6 in the osteopenic group, and 137.5 ±â€Š64.9 in the postmenopausal osteoporosis group (P < 0.001). These differences were maintained after adjustment for body mass index (P < 0.001). The urinary iodine level accurately correlated with the total T-score for the lumbar spine (r = 0.236, P = 0.008). Multiple regression analysis showed that corrected for body mass index, alkaline phosphatase isoenzyme, and urinary deoxypyridinoline, the urinary iodine level was significantly associated with total T-score (beta coefficient = 0.270, P = 0.006). CONCLUSIONS: The urinary iodine level was significantly lower in women with postmenopausal osteoporosis, and iodine replacement may be important in preventing osteoporosis in areas where iodine deficiency is endemic.

RESUMO

AIM: The aim of this study was to compare the effects of topical lidocaine spray, cream and injection on pain perception during intrauterine device (IUD) insertion. METHODS: Multiparous women of reproductive age were randomized into control, lidocaine cream, spray and injection groups. A 10 cm visual analog scale was used for all patients to evaluate pain during the three steps of the IUD insertion procedure. Baseline pain assessment was made immediately after the administration of analgesics, the second pain assessment was performed immediately after use of the tenaculum, and the third pain assessment was performed after IUD insertion. RESULTS: Two hundred patients were enrolled in the study. The groups were similar in terms of demographic characteristics. The lidocaine injection group exhibited higher baseline pain scores (P < 0.001). Pain associated with tenaculum use was lower in the lidocaine spray group. Pain related to IUD insertion was lower in the lidocaine spray and injection groups (P < 0.001); however, lidocaine spray was superior to injection for the reduction of IUD insertion related pain (P = 0.001). CONCLUSION: Lidocaine spray is a good option for reducing the pain experienced during insertion of an IUD. It reduces pain related to both tenaculum use and IUD insertion. Spray application is both easy and rapid. Paracervical lidocaine injection also reduces pain during IUD insertion, but has no effect on tenaculum-related pain; moreover, the injection itself is painful. Therefore, this option is not a plausible method for reducing pain during IUD insertion.

RESUMO

BACKGROUND: Our aim was to compare single incision and conventional laparoscopic surgeries performed for benign adnexal masses with regard to their intraoperative characteristics and postoperative pain levels. MATERIAL AND METHODS: The main outcome measures were laparoscopic entry time, total operation time, amount of bleeding, intraoperative complications, post-operative pain scores, additional analgesic requirements, and length of hospital stay. RESULTS: A total of 71 women, 39 in the conventional laparoscopy group and 32 in the SILS group, participated in the study. Demographic findings did not differ between the two groups. Similarly, rates of intraoperative complications, rates of conversion to laparotomy, pre- and postoperative hematocrit levels were not significantly different between the groups. Laparoscopic entry time was shorter in the SILS group (10.4 ± 5.9 min. vs. 5.28 ± 1.7 min.). However, total operation time was similar in the two groups. The groups did not show significant differences regarding additional analgesic requirements, or postoperative pain scores after 24 h. However, pain scores in the recovery room and after six and 12 h were lower in the SILS group. CONCLUSION: SILS seems to be effective and safe for the treatment of benign adnexal masses. SILS appears to be advantageous regarding postoperative pain especially in the early period.

RESUMO

BACKGROUND: To evaluate amniotic fluid pro- and anti-inflammatory cytokine levels in women with postterm and term pregnancies in labor and not in labor. METHODS: The study involved three groups: postterm (Group 1, n = 29), term in labor (Group 2, n = 28), and control (Group 3, n = 30). All groups were compared with respect to age, gravidity, parity, obstetric history, gestation week, cervical dilatation and effacement, maternal serum C-reactive protein and white cell count, amniotic interleukin 4, 6, and 10 levels, birthweight, and cord blood pH. RESULTS: The amniotic fluid interleukin 10 level was 24.4 ± 8.8 pg/mL in the postterm group, 13.5 ± 5.1 pg/mL in the term in labor group, and 19.8 ± 5.4 pg/mL in the control group (p < 0.001). The amniotic fluid interleukin 4 level was 86.5 ± 57.7 pg/mL in the postterm group, 38.2 ± 29.2 pg/mL in the term in labor group, and 81.9 ± 68.4 pg/mL in the control group (p = 0.002). The amniotic fluid interleukin 6 level was 329 ± 135.1 pg/mL in the postterm group, 252.8 ± 138.7 pg/mL in the term in labor group, and 227.9 ± 114.4 pg/mL in the control group (p = 0.02). There was a positive correlation between gestational age and IL-10 levels (p < 0.05). CONCLUSIONS: Amniotic fluid IL-10 and IL-4 cytokine levels were increased in postterm pregnancy and they decreased with active labor.

RESUMO

The aim of this study was to detect the presence of Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Mycoplasma hominis, Trichomonas vaginalis, and Ureaplasma urealyticum in genital specimens of symptomatic patients. This study also examined the role of U. urealyticum in infections of the lower genital tract. Cervical and urethral samples from 96 patients (46 males, 50 females) were tested using the Seeplex(®) STD6 ACE kit. Consent forms were received and a questionnaire was applied. All statistical analyses were performed using the SPSS statistical software program (version 17.0). Among the samples tested, at least 1 pathogen was detected in 49% of the samples; specifically, the rate of detection of U. urealyticum, M. hominis, C. trachomatis, N. gonorrhoeae, M. genitalium, and T. vaginalis was 29.1%, 10.4%, 8.3%, 7.3%, 6.3%, and 4.2%, respectively. U. urealyticum was detected as the sole pathogen in samples from 10% of female patients and 28.3% of male patients (p = 0.035). U. urealyticum was present in 54.5% (18/33) of samples in which a single pathogen was detected and 71.4% (10/14) of samples in which multiple pathogens were detected. Among men, significant differences in discharge, dysuria, and pruritus were not noted among those with negative results (84.6%, 69.2%, and 38.5%, respectively), among those positive for only U. urealyticum (100%, 66.7%, and 26.7%, respectively), and those positive for N. gonorrhoeae, C. trachomatis, M. genitalium, and T. vaginalis (100%, 93.3%, and 26.7%, respectively). Detection of U. urealyticum, either alone or together with other pathogens, in a symptomatic group of patients is an important finding, particularly in men.

RESUMO

The aim of this study was to investigate the differences of placental elasticity between intra-uterine growth restriction (IUGR) and normal pregnancies to show whether or not there is any association between histopathological changes and placental elasticity. Fifty-five human placentas were collected at delivery, including 25 with IUGR and 30 controls. Strain elastography (SE) was performed ex vivo and all placentas were examined histopathologically. Elasticity index (EI) and histopathological findings were compared between groups. The placental stiffness and presence of histopathological changes were higher in the IUGR group than in controls (p < 0.05). Also, histopathological findings were associated with decreased EI values, but no specific patterns of histologic abnormalities were identified except villitis and delayed villous maturity. Distinct reduced placental elasticity could be the result of the cumulative effects of all the histologic findings in IUGR.

RESUMO

PURPOSE: To evaluated the potential antioxidant agent Legalon (r) SIL (silibinin-C-2',3-bis(hydrogensuccinat)) in the skeletal muscle of rats. METHODS: IRI was achieved via tourniquet application in Wistar-albino rats. Experimental groups were chosen as (i) sham control, (ii) IRI (3+2 h), (iii) IRI and Legalon (r) SIL-50 (50 mg/kg/i.p.), (iv) IRI and Legalon (r) SIL-100 (100 mg/kg/i.p.), and (v) IRI and Legalon (r) SIL-200 (200 mg/kg/ i.p.). Muscle viability (evaluated by triphenyltetrazolium chloride dye method), malondialdehyde, superoxide dismutase, catalase, and glutathione peroxidase were assessed in muscle samples using a spectrophotometer. RESULTS: Although viability of the injured limb non-significantly declined in the IRI group, administration of Legalon (r) SIL did not prevent injury. However, dramatic increase observed in malondialdehyde levels in the IRI group was prohibited by Legalon (r) SIL in a statistically significant manner. In comparison with the sham-control group, IRI and Legalon (r) SIL administration did not cause any significant alterations in the levels of superoxide dismutase, catalase, and glutathione peroxidase. CONCLUSION: Although Legalon (r) SIL was not sufficient to prevent muscle injury in terms of viability, it is found to be an effective option to reduce reactive oxygen species-induced cell injury.

RESUMO

Sarcomas of the vulva in the Bartholin's gland area are extremely rare in adults and only a few cases have been reported in the literature. A 65-year-old female patient without any previous complaint presented to our hospital complaining of a genital lump with progressive enlargement over the last six months. Pelvic examination revealed a 6 × 5 cm solid mass lesion with irregular margins localized in the left Bartholin's gland. Preoperative pathology results indicated a benign lesion, which was subsequently totally excised. Histopathological examination of the lesion revealed leiomyosarcoma. When a lesion is localized in the Bartholin's gland area, preoperative biopsy may suggest benign cytology, which can lead to a delay in diagnosis and curative treatment. Total local excision is the first choice for vulvar-complicated masses in the Bartholin's gland area. The present case is the ninth well-documented case reported in the literature.

RESUMO

OBJECTIVE: The aim of this study was to investigate the effect of metoclopramide on endometrial receptivity with an immunohistochemical investigation of integrin ß3 expression in pregnant rats. MATERIALS AND METHODS: In the present study, the pregnant mice administrated by different doses of metoclopramide were used to explore the effect of metoclopramide on embryo implantation, especially on the endometrial receptivity. RESULTS: The statistical results showed that the number of implanted embryos was gradually declining along the increasing dose of metoclopramide. When the administrated dose of metoclopramide was 3 mg/kg per day, great changes were observed in the exposed uterine morphology and down-regulated integrin ß3 were also found in high dose metoclopramide-exposed mice. CONCLUSION: Metoclopramide exposure, especially in high doses may alter endometrial receptivity by effecting integrin expression on decidual tissue which can decrease pregnancy rates. This drug should only be recommended for use during pregnancy when benefit outweighs the risk.

RESUMO

OBJECTIVE: To evaluate the role of rapamycin in the prevention of diabetic oxidative stress and the regulation of angiogenic factors. DESIGN: Experimental animal study. METHODS: Diabetes was induced in 20 adult male Wistar rats by a single intraperitoneal administration of streptozotocin (60 mg/kg). Rats were randomly assigned into diabetic and rapamycin groups (n = 10). Ten healthy normal adult male rats of same age formed the control group. All groups were followed for 3 months. Rapamycin group received 1 mg/kg rapamycin via orogastric gavage during the last 4 weeks. At the end of 12 weeks, rats were sacrificed and biochemical oxidative stress markers (malondialdehyde and nitrotyrosine), together with vascular endothelial growth factor, hypoxia-inducible factor-1α, and pigment epithelium-derived factor, were measured in the retina. Blood biochemical analyses were also done. RESULTS: In the diabetic group, retinal malondialdehyde and nitrotyrosine levels were increased in comparison with control and rapamycin groups (p < 0.05). Rapamycin suppressed oxidative stress and showed a beneficial effect. It also decreased all angiomodulator cytokines compared with the diabetic group (p < 0.05). Correspondingly, rapamycin also decreased plasma malondialdehyde levels compared with the diabetic group (p = 0.037). CONCLUSIONS: Rapamycin may have a protective role against diabetes-induced oxidative retinal injury and may decrease angiomodulator cytokines.

RESUMO

Hydatid disease is an endemic infection which can affect any organ, mainly the liver and lungs. Peritoneal echinococcosis is usually known to occur secondary to hepatic hydatid cyst rupture into the peritoneal cavity. An isolated cyst in the pelvic cavity is considered as primary only when there are no other hydatid cysts. Herein, we report an isolated pelvic-cervical hydatid cyst which presented without any involvement of the other abdominal organs or lungs. Our patient, a 27-year-old woman with the primary complaints of dyspareunia and chronic pelvic pain, had thin-walled large cystic mass originating from the cervix, diagnosed by ultrasonography. She underwent surgery with the most likely initial diagnosis of exophytic fibroid with cystic degeneration. Gynecologists should be aware of the possibility of isolated primary hydatid cyst of the pelvic cavity and should consider this condition in the differential diagnosis of cystic pelvic masses, especially in areas where the disease is endemic.

RESUMO

OBJECTIVE: To evaluate the prevalence of HPV DNA and cervical cytological abnormalities, to compare cervical cytology results and HPV DNA and to define HPV types distribution in a large series of Turkish women who have undergone HPV analysis in hospitals that are members of the Turkish Gynecological Oncology Group. MATERIAL AND METHOD: Between 2006 and 2010, a total of 6388 patients' data was retrospectively evaluated at 12 healthcare centers in Turkey. Demographic characteristics, cervical cytology results, HPV status and types were compared. RESULTS: The mean age of the patients was 38.9±10.2. Overall, 25% of the women were found to be HPV positive. Presence of HPV-DNA among patients with abnormal and normal cytology was 52% and 27%, respectively. There was significant difference with respect to decades of life and HPV positivity (p < 0.05). HPV was positive in (within the HPV (+) patients) 37%, 9%, 27%, 20%, 22%, and 41% of the ASCUS, ASC-H, LSIL HSIL, glandular cell abnormalities, and SCC cases respectively The most common HPV types in our study were as follows; HPV 16 (32%), HPV 6 (17%), HPV 11 (9%), HPV 18 (8%), HPV 31 (6%), HPV 51 (5%), HPV 33 (3%). CONCLUSION: In this hospital based retrospective analysis, HPV genotypes in Turkish women with normal and abnormal cytology are similar to those reported from western countries. Further population based prospective multicenter studies are necessary to determine non-hospital based HPV prevalence in Turkish women.

RESUMO

BACKGROUND: Existing studies suggest that music therapy can have favorable effects on hypertension and anxiety. We therefore set out to investigate the effect of Turkish classical music. OBJECTIVES: To investigate whether Turkish classical music has positive effects on blood pressures and anxiety levels in elderly patients. DESIGN, SETTING AND SUBJECTS: This was a randomized controlled trial performed on 60 hypertensive patients living in a local elderly home in Adana, Turkey. METHODS: Following the completion of a socio-demographic form for each patient, Hamilton anxiety scale was applied. Thereafter, the subjects were randomly divided into two equal-size groups and were allowed to either listen to Turkish classical music (music therapy group) or have a resting period (control group) for 25 min. OUTCOME MEASURES: The primary and secondary outcome measures were blood pressure and Hamilton anxiety scale scores, respectively. RESULTS: The mean reduction in systolic blood pressure was 13.00 mmHg in the music therapy group and 6.50 mmHg in the control group. The baseline adjusted between treatment group difference was not statistically significant (95% CI 6.80-9.36). The median reductions in diastolic blood pressures were 10 mmHg both in the music therapy and control groups. The between treatment group difference was not statistically significant (Mann-Whitney U test, P = 0.839). The mean reduction in HAMA-A was 1.63 in the music therapy group and 0.77 in the control group. The baseline adjusted between treatment group difference was not statistically significant (95% CI 0.82-1.92). CONCLUSION: The study demonstrated that both Turkish classical music and resting alone have positive effects on blood pressure in patients with hypertension.

RESUMO

PURPOSE: To investigate the potential beneficial effect of silibinin in ischemia-reperfusion injury (IRI) of skeletal muscle. METHODS: Under urethane anesthesia, four experimental groups were established in Balb/c mice: I) Sham-control, II) IRI (Tourniquet-induced) (2+1 h), III) IRI+ethanol (10%), and IV) IRI+silibinin (50 mg/kg/IP). The viability of muscle (left) was evaluated by the triphenyltetrazolium chloride dye method and calculated as the percentage of the contralateral control muscle (right). Malondialdehyde, superoxide dismutase, and catalase were measured in the gastrocnemius muscle via a spectrophotometer. RESULTS: The viability of gastrocnemius muscle in group II was significantly lower in comparison with that seen in group I. The administration of either ethanol or silibinin rendered the tissues to recover nearly to the baseline level. Additionally, malondialdehyde levels were higher in group II than those in group I. The application of silibinin prior to the reperfusion attenuated these to the control levels. However, malondialdehyde levels in the ethanol administrated group were reduced as well. The enhanced superoxide dismutase activity seen in the IRI group was not diminished in the animals treated with either silibinin or ethanol. Similarly, there were no differences between groups regarding the catalase activities. CONCLUSION: Ethanol seems to be effective in attenuating IRI in skeletal muscle and no definite conclusion can be made on silibinin effect.
