RESUMEN

Arsenic (As) is a toxic metalloid that affects many organs through drinking water. This study aims to examine the efficacy of ozone therapy on chronic arsenic toxicity. Twenty-four male Wistar albino rats were housed in individual cages and grouped as control, As, O3, and As + O3. As was applied by adding 5 mg/kg/day in drinking water for 60 days. Ozone therapy was applied at 0.5 mg/kg/day (i.p.) O3 in the last 5 days of the experimental period. Tissues were harvested and analyzed for histopathological injury and apoptotic markers. There was no significant difference between the As + O3 and O3 groups (p = 0.186 and p = 0.599) for light microscopic criteria: inflammatory cell infiltration and hydropic degeneration in liver tissue.In TUNEL assessments, similar outcomes were obtained in the control and As + O3 groups. A statistically significant increase was observed in p53 and Caspase 3 (Casp-3) expression levels in the As group compared to the O3 and As + O3 groups. There was no significant difference between the As + O3 and O3 groups on peritubular hemorrhage and desquamation parameters in kidneys (p = 0.147 and p = 0.094). The KIM-1 expression level was significantly increased in the As group compared to the As + O3 group (p = 0.01), and the Casp-3 expression level was not significantly changed in the O3 group compared to the As + O3 group (p = 0.59). In conclusion, it is determined that ozone therapy has ameliorative effects on the microscopic injury of liver and kidney tissues. In addition to microscopic improvement, KIM-1 gene expression levels were ameliorated in the kidneys. The apoptotic cell counts and the Casp-3 and p53 gene expression levels were decreased by O3 administration. Thus, ozone therapy can be a treatment choice for As toxicity.

RESUMEN

Arsenic (As) is a toxic substance that damages the human body through exposure to drinking water. This exposure damages many organs and tissues in the body, especially the liver and kidneys. Hyperbaric oxygen (HBO2) therapy is a treatment method that acts by reducing oxidative stress parameters in tissues with high-pressure oxygen. Based on this, our study aimed to investigate the effectiveness of HBO2 on liver and kidney tissues with chronic arsenic toxicity. In the study 24 male Wistar albino rats (220-300 g, two to three months old) were equally divided into four groups: Control; As; HBO2; and As+HBO2. All animals were housed in individual cages. The toxicity model was created by adding arsenic to drinking water at a dose of 5 mg/kg/day for 60 days. HBO2 was applied 2 ATA pressure for 90 minutes a day for five days. At the end of the study, liver and kidney tissues were taken and stored for analysis. In liver tissue, histopathological showed that arsenic reduced inflammatory cell infiltration, sinusoidal congestion, and hydropic degeneration, while HBO2 increased these measures. Similar results were found by TUNEL method. In kidney tissue, both histopathologic and TUNEL method examinations found similar results with the liver: The As group was more damaged than the As+HBO2 group.

RESUMEN

Valproic acid (VPA) is a anticonvulsant and mood-stabilizing agent used to treat epilepsy in patients of all ages. However, it can cause hepatotoxicity with increased oxidative stress. Melatonin (MEL) is known as antioxidant and antiinflammatory agent. Therefore, the present study designed to investigate the probable protective role of melatonin against VPA-induced liver toxicity. For that purpose, 28 Wistar rats were randomly selected and divided into four groups, namely the Group C (vehicle), VPA (500 mg/kg/day VPA), MEL + VPA (10 mg/kg/day melatonin + 500 mg/kg/day VPA) and MEL (10 mg/kg/day melatonin). The agents were given by oral gavage for 14 days. Blood and liver tissue samples from all the rats were harvested on the 15th day of experiment. Biochemical analyses were conducted on the blood samples. The levels of malondialdehyde (MDA), superoxide dismutase (SOD), alpha glutathione S-transferases (α-GST), nuclear factor-κB (NF-κB), myeloperoxidase (MPO) and changes in gene expression were examined in the liver tissues. Also, liver histopathological analyses were conducted. VPA administration significantly increased the levels of α-GST, MDA, NF-κB and of IL-1ß, TNF-α gene expression in the liver compared to Group C. Moreover, vacuolization, hydropic degeneration, inflammatory cell infiltration, and sinusoidal congestion were commonly detected in the VPA-treated group along with the highest apoptotic index (TUNEL staining) values. Melatonin administration was revealed to exhibit powerful protective properties at cellular, inflammatory and oxidative level activities against VPA-induced liver toxicity. Therefore, melatonin administration may be used as an adjuvant therapy against to VPA-induced liver toxicity.

RESUMEN

In recent years hyperbaric oxygen (HBO2) therapy has been considered as an effective method for the treatment of gentamicin (GM)-induced renal toxicity. However, the findings related to the use of HBO2 for GM toxicity are limited and contradictory. The aim of this study is to investigate the protective role of HBO2 on GM-induced nephrotoxicity. For this purpose, Wistar albino rats (n=28) were randomly divided into four equal groups: C, HBO2, GM and GM+HBO2. GM (100 mg/kg, ip) and HBO2 were applied over seven days. On the eighth day blood and kidney tissue samples were harvested. The albumin, creatinine, and urea levels were determined from serum samples. Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) activities, malondialdehyde (MDA), total antioxidant status (TAS) and total oxidant status (TOS) values were analyzed spectrophotometrically. The relative expression level of TNF-α, IL-1ß and Kim-1 gene were determined by qRT-PCR assays; histopathologic investigation was completed in kidney tissue samples. Serum urea, albumin and creatinine levels significantly increased in the GM group compared to the GM+HBO2 group. For antioxidant parameters the GM+HBO2 group was not statistically different from the C group but was significantly different compared with the GM group. TNF-α, IL-1ß and Kim-1 gene expression levels in the GM group were statistically increased compared to the GM+HBO2 group (p=0.015, p=0.024, p=0.004) respectively. Severe tubular necrosis, epithelial desquamation and mild peritubular hemorrhage were observed in the GM-administrated group, while HBO2 exposure ameliorated these alterations. In conclusion, HBO2 exposure may be defined as a potential method for the prevention of GM-induced renal toxicity.

RESUMEN

OBJECTIVE: Ankaferd Blood Stopper (ABS) is a medicinal plant extract used topically as a hemostatic, anti-inflammatory, and anti-oxidant agent. Its cytoprotective effect mainly depends on its pleiotropic properties by modulating inflammatory mediators such as IL-1ß, IL-6, and TNF-α. This study aims to test the possible therapeutic effect of ABS in the treatment of erosive and inflammatory conditions occurring in the uterine cervix. METHODS: Twenty-four female Wistar Albino rats were used in the present study. Trichloracetic acid was applied intravaginally to establish an experimental rat model of cervicitis. The rats were randomly divided into three groups: group I (injury), group II (injury+isotoinc saline), and group III (injury+ABS). After 3 estrous cycles of ABS and isotonic saline treatment, the amount of inflammation, vascular congestion and erosion were evaluated in the cervical tissues by using a modified semi-quantitative scale of 0-3. Immunohistochemical staining with monoclonal antibodies against IL-1ß was also performed. RESULTS: Compared with group I and II, the ABS group showed the least inflammatory cell infiltration, vascular congestion and cervical erosion, compared with the ABS group prominent IL-1ß staining observed in group I and group II. CONCLUSION: Our data suggest that ABS is a highly effective alternative to induce normal cervical epithelium and can be used safely in the treatment of cervical inflammation with or without cervical erosion.

RESUMEN

SUMMARY OBJECTIVE: Ankaferd Blood Stopper (ABS) is a medicinal plant extract used topically as a hemostatic, anti-inflammatory, and anti-oxidant agent. Its cytoprotective effect mainly depends on its pleiotropic properties by modulating inflammatory mediators such as IL-1β, IL-6, and TNF-α. This study aims to test the possible therapeutic effect of ABS in the treatment of erosive and inflammatory conditions occurring in the uterine cervix. METHODS: Twenty-four female Wistar Albino rats were used in the present study. Trichloracetic acid was applied intravaginally to establish an experimental rat model of cervicitis. The rats were randomly divided into three groups: group I (injury), group II (injury+isotoinc saline), and group III (injury+ABS). After 3 estrous cycles of ABS and isotonic saline treatment, the amount of inflammation, vascular congestion and erosion were evaluated in the cervical tissues by using a modified semi-quantitative scale of 0-3. Immunohistochemical staining with monoclonal antibodies against IL-1β was also performed. RESULTS: Compared with group I and II, the ABS group showed the least inflammatory cell infiltration, vascular congestion and cervical erosion, compared with the ABS group prominent IL-1β staining observed in group I and group II. CONCLUSION: Our data suggest that ABS is a highly effective alternative to induce normal cervical epithelium and can be used safely in the treatment of cervical inflammation with or without cervical erosion.


RESUMO OBJETIVO: Ankaferd Blood Stopper (ABS) é um extrato de plantas medicinais utilizado topicamente como um agente hemostático, anti-inflamatório e antioxidante. O seu efeito citoproteico depende principalmente das suas propriedades pleiotrópicas por meio da modulação de mediadores inflamatórios tais como IL-1β, IL-6 e TNF-a. O objetivo deste estudo é testar o possível efeito terapêutico do ABS no tratamento de condições erosivas e inflamatórias que ocorrem no colo uterino. MÉTODOS: Vinte e quatro ratas Wistar Albino foram utilizadas no presente estudo. O ácido tricloroacético foi aplicado intravaginalmente para estabelecer um modelo experimental de cervicite em ratos. Os ratos foram divididos aleatoriamente em três grupos: grupo I (lesão), grupo II (lesão + fisiológico sérico) e grupo III (lesão + ABS). Após três ciclos estrais de ABS e tratamento fisiológico sérico, as quantidades de inflamação, congestionamento vascular e erosão foram avaliadas nos tecidos cervicais usando uma escala semiquantitativa modificada de 0-3. Coloração imuno-histoquímica com anticorpos monoclonais contra IL-1β também foi realizada. RESULTADOS: Em comparação com os grupos I e II, o grupo ABS mostrou menos infiltração de células inflamatórias, congestionamento vascular e erosão cervical. Além disso, em comparação com o grupo ABS, observou-se uma coloração proeminente de IL-1β no grupo I e no grupo II. CONCLUSÃO: Nossos dados sugerem que o ABS é uma alternativa altamente eficaz para induzir o epitélio cervical normal e pode ser utilizado com segurança no tratamento da inflamação cervical com ou sem erosão cervical.
