Islam is a religion that was establishedin the 7th century by the Prophet Muhammad who was commissioned as a Messenger of God. It is also the modern or latest version of the message sent by God through some prophets, e.g. Adam, Noah, Abraham, Moses and Jesus. Not only is it associated with the mental aspect, however, it also impacts every part of life, from eating and sleeping to working and playing. It can be, therefore, considered a way of life.Meanwhile, one’s lifestyle has recently come to have great meaning especially in the developed countries. Methods to assess lifestyle are suggested by some authorities such as Breslow and Morimoto. Accordingly, we have tried to investigate whether Muslims, the followers of Islam, have a desirable lifestyle as defined in today’s terms, i.e. the cultural dependence of the lifestyle formation.As a result, Muslims seeking to live in accordance with the doctrine of Islam may have a relatively good lifestyle. Islam may also be associated with the relief from the mental stress and give Muslims a guideline to live a happier life.

Objectives: The purpose of this study was to investigate the effect of tomato juice drinking on the anti-mutagenicity of saliva. Methods: Subjects were 22 healthy male university students. They were divided into tomato group and control group. The tomato group drank tomato juice for 10 days. The anti-mutagenicity of saliva was measured using the umu test. Results: In the tomato group, there was a significant increase in the inhibiting capacity of saliva on the mutagenicity of AF-2 after tomato juice drinking for 10 days. This increase was, however, temporary. In the control group, there was no such change in the inhibiting capacity of saliva. Conclusions: These findings suggest the significant effect of tomato juice drinking on the anti-mutagenicity of saliva. In addition, lycopene may have played an important role in its mechanism.

Objectives: To use the evaluation of a specific brain function obtained by optical topography. This system uses a non invasive method to measure brain function, unlike other major systems. Methods: Twelve optical fibers were attached to the subject's head. Hemodynamic changes in the motor cortex were measured during finger tapping before and after alcohol intake for each ALDH2 genotype. Results: Different hemodynamic changes in the motor cortex were observed among the ALDH2 genotypes. Conclusions: Optical topography is a useful tool for evaluating specific brain functions. Further research is needed on the relations between various environmental factors and brain functions by optical topography.

The relations between salivary variables, lifestyle and mental health status were investigated for 61 healthy female university students. The salivary secretion rates were significantly higher in the good lifestyle group compared with the poor lifestyle group. Among the 8 lifestyle items tested, “eating breakfast” and “mental stress” were significantly related to the salivary secretion rates. The present findings suggest that the acquisition of a good lifestyle is also very important from the viewpoint of the prevention of oral disease. A highly significant correlation (r=0.97; p<0.01) between the salivary cortisol levels and the cortisol secretion rates when controlled for the salivary secretion rates was also observed. This suggests that there is a high correlation between the intact salivary cortisol levels and the total cortisol quantity per unit time. Therefore, both these values can be used as a good index for the salivary cortisol determination.

The purpose of this study was to investigate the effect of weight reduction on the anti-mutagenicity of human saliva. Subjects were 16 male college judo players. The anti-mutagenicity of the saliva was measured using the umu test. There was an inhibiting effect of the saliva on the mutagenicity of AF-2. However, a modifying effect of the saliva on Trp-P-1 was not observed. On the day before a competition and 7 days after the competition, the inhibiting capacity of the saliva for the mutagenicity of AF-2 decreased and increased in two non-weight reduction and two weight reduction groups, respectively. However, on the day before the competition, the changed body weights (r=−0.77, p<0.01) and BMI (r=−0.77, p<0.01) were significantly correlated with that of the inhibiting capacity of the saliva for the mutagenicity of AF-2. In addition, the BMI at 20 days before the competition was not significantly but markedly correlated with it (r=0.50, p=0.057). At 7 days after the competition, however, these correlations were not found. These findings suggest a unique correlation between the anti-mutagenicity of human saliva and body weight or BMI.

The purpose of this study was to investigate the effect of weight reduction prior to a competition on the salivary cortisol level for first-rate judo players. Subjects were divided into three groups by the weight reduction rate. On the day before the competition, the cortisol levels of the low- and high-weight reduction group showed a tendency to decrease and were significantly lower than that of the non-weight reduction group (p<0.05). However, with regard to the change in the stress indices, there was a difference between the high- and low-weight reduction groups. In the high-weight reduction group alone, there was a significant increase in the stress indices on the day before the competition (p<0.05). These findings suggest that the HPA axis is affected during the relatively early stage of weight reduction and mental stress is increased at the higher weight reduction rate.

A 74-year-old man undergone mitral valve plasty. After cessation of cardiopulmonary bypass, bleeding persisted from the cardioplegia injection site and dilatation of the ascending aorta with discoloration was observed. The diagnosis of type A aortic dissection extending to the descending aorta was made by transesophageal echocardiogram. Replacement of the ascending aorta was performed under deep hypothermic circulatory arrest. The postoperative course was uneventful. The false lumen of the aortic arch and descending aorta was thrombosed completely on postoperative computed tomography. Intraoperative aortic dissection is a rare but fatal complication of cardiopulmonary bypass. Prompt recognition and appropriate surgical management are of prime importance.

OBJECTIVESThe purpose of this study was to compare the anti-mutagenicity of Salivette and test-tube sampling saliva. In addition, the relation between the inhibiting and pH-buffering capacities of saliva was investigated.
METHODSSubjects were 52 healthy female university students. The collection of saliva samples was carried out using 2 sampling devices; test-tube and Salivette. The anti-mutegenicity of the saliva was measured using the umu test.
RESULTSThe inhibiting capacity of Salivette-saliva was significantly lower compared with that of testube-saliva (p<0.01,t test). However, there was a significant correlation between them (r=0.35; p<0.05). In addition, there was a significant correlation between the inhibiting and pH-buffering capacities of saliva (r=-0.36; p<0.05).
CONCLUSIONSThese findings suggest that both the Salivette and the test-tube may be appropriate as saliva-sampling devices. In addition, they suggest that the bicarbonates might inhibit the anti-mutagenicity of saliva, or that the activity of substances related to the anti-mutagenicity of saliva might be dependent on pH.
