Exposure to X-rays (ionizing radiation) may cause chromosomal aberrations (CA) in somatic or germinative cells in exposed individuals, and may lead to manifestations of diseases such as cancer. This study was carried out to assess the CA frequency in lymphocytes obtained by means of temporary culture of peripheral blood from dentists in Londrina, Paraná, Brazil, who have worked for more than ten years with X-rays. The results obtained from the experimental group were compared with a matched negative control group, which had never been exposed to X-rays. All individuals, dentists and controls, answered a personal questionnaire, from which a profile of each group was obtained. Slides, prepared after the cultures, were stained with Giemsa, and 100 to 200 metaphase cells were analyzed per individual. CA frequencies and types were registered and statistical tests were not necessary to evaluate the obtained data. The analysis of mitotic index (MI) did not indicate significant differences (p < 0.05) between the group of individuals exposed to X-rays and the control group. The analyzed confounding factors did not influence the results of MI and CA frequencies.

Membranes that aid the guided bone regeneration (GBR) process have been the subject of studies of compatible biomaterials that contribute to this repair process. The present study compared different membranes used in critical-size defects of rat calvaria by assessing GBR as well as histological, histomorphometric, and immunohistochemical reactions. Forty-eight male albino Wistar rats were randomly allocated into four groups (n = 12 each), namely, C: membrane-free control group (only blood clot, negative control group); BG: porcine collagen membrane group (Bio-Gide®, positive control group); GD: bovine cortical membrane group (first experimental group); and GDF: thicker bovine cortical membrane group (second experimental group). Rats were euthanized at 30 and 60 days postoperatively. Quantitative data from the histometric analysis were submitted to two-way ANOVA and Tukey’s posttest when p<0.05. Histomorphometric results of the thicker bovine cortical membrane at 30 and 60 days were promising, showing improved new bone formation values (p<0.05), and the CD group presented similar results in both analysis periods, being surpassed only by the GDF group (p<0.05). The immunohistochemical results were associated with the histomorphometric data. A less-thick membrane also assisted in GBR. All membranes promoted GBR, especially the positive control and experimental groups.

OBJECTIVEOver the last decade, a number of authors have investigated the utility of different biological and synthetic matrices as alternatives to conventional nerve grafts. However, the autologous nerve graft remains the gold standard, even though it often involves using a pure sensory nerve to reconstruct a mixed or even a pure motor nerve. Furthermore, limited donor sites often necessitate a significant mismatch of needed nerve tissue, especially for large proximal nerve defects such as brachial plexus lesions. Here, the authors present a new technique that overcomes these problems: the fascicular shift procedure (FSP). A fascicular group of the nerve distal to the injury is harvested in a sufficient length to bridge the nerve defect.METHODSThe method of fascicular shifting was tested at the sciatic nerve in 45 Lewis rats. In the experimental group, a 15-mm nerve defect was created and reconstructed with a fascicular group that was harvested directly distal to the gap. This group was compared with 1 negative control group (defect without reconstruction) and 3 positive control groups (sensory, motor, and mixed graft). After 12 weeks of nerve regeneration, outcome was evaluated using retrograde labeling, histomorphometric analysis, and muscle force analysis.RESULTSAll reconstructed groups showed successful regeneration with various levels of function. The negative control group showed minimal force measurements that were of no functional value. The fascicular shift provided sufficient guidance to overcome nerve defects, had higher (p < 0.1) motor neuron counts (1958.75 ± 657.21) than the sensory graft (1263.50 ± 538.90), and was equal to motor grafts (1490.43 ± 794.80) and mixed grafts (1720.00 ± 866.421). This tendency of improved motor regeneration was confirmed in all analyses. The mixed graft group was compared with the experimental group to investigate the influence of the potential damage induced by the fascicular shift distal to the repair site. However, none of the analyses revealed an impairment of nerve regeneration for both the tibial and common peroneal index muscles.CONCLUSIONSThis study demonstrates that harvesting a transplant from the nerve segment distal to the injury site offers a mixed graft without causing additional donor-site morbidity. These grafts perform statistically better than a standard sensory graft in terms of motor recovery. The fascicular shift presents a novel method to reconstruct large proximal nerve defects, making it immensely attractive in brachial plexus reconstruction.

One of the commonly used chemotherapy drugs is cyclophosphamide. However, the use of cyclophosphamide can provide various toxic effects. The most common toxic effect of cyclophosphamide is bone marrow suppression with anemia as one of its markers. The antioxidant content of cainito leaf potentially increase the production of blood cells, especially erythrocytes. The aims of this study is determining the effectiveness of the cainito leaf ethanol extract against cyclophosphamide induced mouse erythrocyte count in vivo. A sample of 20 male wistar rats was divided into five groups; normal group, negative control group, and three groups of ethanol extract of cainito leaf with dose 100 mg/kgBW, 200 mg/kgBW, and 400 mg/kgBW were administered for one week followed by intraperitoneal cyclophosphamide with dose 50 mg/kgBW as much as one time. One Way Anova Test result showed a significance of 0.015 (p<0.05). However, the LSD test results showed no significant different results between the negative control group and the treatment group. The conclusion was that there was no difference in the amount of erythrocytes in mice given only cyclophosphamide with previous rats given cainito extract.

The objective of this study was to evaluate the antipyretic effect of key lime (Citrus aurantifolia L.) leaf extract on white rats (Rattus norvegicus) induced fever by using DPT vaccine. Thirty male white rats with the body weight of ±200 grams and the age of 2-3 months old were used in this study. Those rats were grouped equally into five groups, consisted of a negative control group (2 mL aquabidest), a positive control group (acetaminophen 6.3 mg/100 g of body weight), the first dose of key lime leaf extract (1.26 mg/100 g of body weight), the second dose (2.52 mg/100 g of body weight) and the third dose (5.04 mg/100 g of body weight). The measurement of rat temperature was conducted before and 2 hours after getting DPT vaccine, and every 30 minutes posttreatment until 120 minutes. Data at the 120th minute were analyzed by using One-Way Anova test. The results of One-Way Anova test showed that there were significant differences (p<0.05) among treatment groups. The results of post-hoc test analysis showed that the significant differences (p<0.05) were found between a negative control group and four other groups. There was no significant difference (p>0.05) between a positive control group and three groups of key lime leaf extract. It concluded that the key lime leaf extract has an antipyretic effect on white male rats.
