Effect of fullerenol C60 on lung and renal tissue in lower extremity ischemia‑reperfusion injury in sevoflurane‑treated rats

The aim of the present study was to examine the effect of fullerenol C60 on lung and kidney tissue in sevoflurane‑treated rats with lower extremity ischemia‑reperfusion (IR) injury. A total of 30 Wistar albino rats weighing 225‑275 g were used and were equally divided into five groups (n=6/group): i) Sham; ii) IR; iii) IR‑fullerenol C60 (IR‑FUL); iv) IR‑sevoflurane; and v) IR‑fullerenol C60‑sevoflurane (IR‑FUL‑SEVO). Fullerenol C60 was administered intraperitoneally prior to lower extremity IR induction and sevoflurane was administered during the IR injury. Subsequently, lung and kidney histopathological examinations, and serum biochemical analyses were performed. Lung tissue showed markedly increased congestion and neutrophil infiltration in the IR group compared with in the sham group, and notable decreases in congestion and neutrophil infiltration were observed in the treatment groups compared with in the IR group. In the histopathological evaluation of the kidney samples, vacuolization, loss of brush border in tubular epithelial cells, tubular epithelial loss and varying degrees of tubular damage were observed in all groups that underwent IR. There was a significant increase in the mean renal tubule injury score in all IR groups compared with that in the sham group. In addition, the mean kidney injury score was significantly lower in the IR‑FUL and IR‑FUL‑SEVO groups than that in the IR group. It was observed that the expression levels of tumor necrosis factor‑α, interleukin 1β and intercellular adhesion molecule 1 in the lung and kidney tissues were increased following IR, and were decreased in the groups treated with fullerenol C60 and sevoflurane. Notably, it was determined that the reduction in cytokine expression was greatest in the IR‑FUL group. When the oxidant status parameters in the lungs and kidneys were examined, thiobarbituric acid reactive substances levels, and catalase and glutathione S‑transferase enzyme activities were significantly different in the groups receiving sevoflurane or fullerenol C60 treatment compared with those in the IR group. The present study demonstrated the protective effects of fullerenol C60 on the lung and kidney tissues of rats under sevoflurane anesthesia after establishment of lower extremity IR. The results of the present study showed that fullerenol C60 can reduce oxidative and histopathological damage in the lungs and kidneys following IR of the lower extremities.

Which maternal personality traits affect child behaviour during dental treatment

AIM

Maternal personality traits affect child dental behaviour and have a potential link with dental treatment methods. This study aims to evaluate which maternal personality traits affect child dental behaviour.

MATERIALS AND METHODS

Research was carried out upon 60 children aged between 3-12 years, who had been admitted to our clinic for tooth extraction. All children were evaluated by means of the Frankl Behavior Scale (FBS): degrees I and II represent negative behaviours, while III and IV positive behaviour. Thirty children with FBS degree III and IV were assigned to Group I and 30 children with FBS degree I and II were assigned to Group II. Children in Group I underwent tooth extraction with local anaesthesia. Children in Group II underwent tooth extraction under deep sedation. During the first visit, the mothers were tested with the Minnesota Multiphasic Personality Inventory to evaluate personality traits. All mothers in Group I and half the mothers in Group II filled a complete and valid test.

RESULTS

Group I and II mothers were compared according to the test results: scores of the Minnesota Multiphasic Personality Inventory (MMPI) test were significantly higher in Group II (p<0.05).

CONCLUSION

We hypotetise that character features of mothers of children with negative dental behaviour and positive dental behaviour are different and affect child dental behaviour.

Are there any effects of Sevoflurane and Desflurane anaesthesia on blood glucose levels in acute hyperglycemic diabetic rats?

AIM

The aim of this study was to investigate blood glucose level of desflurane and sevoflurane on blood glucose in diabetic rats undergoing acute hyperglycemia.

MATERIALS AND METHODS

In this study, 30 male Wistar albino rats were included. Diabetes was induced by a single IP injection of streptozotocin. After the effects of chronic diabetes encountered, diabetic rats were randomly assigned into diabetic control (group DC), diabetic hyperglycemia group (group DH), diabetic hyperglycemia group with desflurane (group DH-D), and diabetic hyperglycemia group with sevoflurane (group DH-S) groups. The normoglycemic groups received an IP injection of the same amount of saline. Hyperglycemic diabetic rats were anaesthetized by desflurane 6 % or sevoflurane 2 % at a dose, by which minimal alveolar concentration (MAC) for rats would be one. The drugs were given for 4 hours within 100 % oxygen at a rate of 6 L.min-1. One hour after cessation of inhalation anesthesia, blood glucose levels were determined at 1st, 4th and 24th hours. 24 hours after the anaesthesia.

RESULTS

Serum glucose was detected to be significantly lower in Group C, when compared to Groups DC, DH, DH-D and DH-S (p = 0.002, p = 0.001, p = 0.002, p = 0.003, respectively). Blood glucose levels in the diabetic groups were similar at the end of 6 weeks period, after hyperglycemia and anaesthesia induction.

CONCLUSION

We found out that sevoflurane and desflurane administrations in hyperglycemic rats were both related with insignificant blood glucose level increase at early post anaesthesia period and at post anaesthesia 24th hours. We still think that patients undergoing anaesthesia protocols with acute hyperglycemia need relatively longer follow up periods (Tab. 1, Ref. 28).
