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.

A study was conducted to examine the relationship between percent body fat (%fat) and medical examination parameters. The subjects were 250 women aged 17 to 68 years, who neither drank nor smoked. The results obtained were as follows:
After controlling for the effects of age and maximal oxygen intake per kilogram body weight (VO₂max/wt), %fat showed a significant correlation with high-density lipoprotein cholesterol (HDL-C), total cholesterol/HDL-C ratio (TC/HDL-C), β-lipoprotein (β-L), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic tansaminase (GPT), uric acid (UA), white blood cell count (WBC), red blood cell count (RBC), systolic blood pressure (SBP), and diastolic blood pressure (DBP) . Values of %fat calculated from each regression equation when HDL-C=38mg/dl, TC/HDL-C=4.9, β-L=500 mg/dl, GOT=41mu/ml, GPT=46 mu/ml, UA=5.7mg/dl, WBC=8500/mm3, RBC=520×104/mm3, SBP=159 mmHg, and DBP=94 mmHg were 32.2%, 31.9%, 30.8%, 35.4%, 36.4%, 31.8%, 30.7%, 35.0%, 33.8% and 32.6%, respectively.
The subjects were then divided into 2 groups, above (above group) or below (below group) 30%, 31%, 32%, 33%, 34% or 35% body fat. Wherever the subjects were divided into 2 groups at these values of %fat, the above group showed a significantly higer occurrence of abnormal values for medical parameters than the below group.
The subjects were further divided into 3 groups: 154 subjects with %fat below 29.9% (N group), 47 subjects with %fat between 30% and 34.9% (MO group), and 49 subjects with %fat above 35% (O group) . The O group showed significantly higher occurrence of abnormal values for medical parameters than the MO and N groups. The O group also showed a significantly higher mean value of DBP than the MO and N groups. Furthermore, the O group showed a significantly lower mean value of HDL-C and significantly higher mean values of TC/HDL-C, UA, GOT, GPT, SBP, FBS than the N group. There was no significant difference between the N and MO groups in the occurrence of abnormal values for medical parameters. However, the MO group showed a significantly lower mean value of HDL-C and significantly higher mean values of TC/HDL-C, UA and β-L.
These results suggest that the values of medical parameters become poorer when %fat exceeds 30%, a level widely used in Japan as a criterion for evaluation of obesity.
The subjects were further divided into 3 groups: 50 subjects who were non-obese and fit (NF group) ; 104 subjects who were non-obese and unfit (NU group) ; 88 subjects who were obese and unfit (OU group) . There were significant differences in the occurrence of abnormal values for medical parameters among these groups. The NF group showed the lowest values, followed by the NU and OU groups. Thus, it seems preferable to evaluate individuals using a combination of %fat and VO₂max/wt.

A study was conducted to derive a criterion for evaluation of obesity based on relationships between percent body fat (%fat) and clinical parameters. The subjects were 457 men aged 18 to 73 years. The results obtained were as follows:
After controlling for the effects of age, maximal oxygen intake per kilogram body weight (VO₂max/wt), alcohol intake and cigarette smoking, %fat showed significant correlations with high-density lipoprotein cholesterol (HDL-C), total cholesterol/HDL-C ratio (TC/HDL-C), fasting blood sugar (FBS), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), γ-glutamyl transpeptidase (γ-GTP), white blood cell count (WBC), red blood cell count (RBC), systolic blood pressure (SBP), and diastolic blood pressure (DBP) . Values of %fat estimated from borderline values of these clinical parameters ranged from 17.9% to 20.4%.
When the subjects were divided into 11 groups from a below 12% fat group to an above 22% fat group, the 18%, 20%, 21% and above 22% fat groups showed significantly higher occurrence of abnormal values for clinical parameters than the below 12% fat group.
When the subjects were divided into 2 groups, i, e, above (above group) or below (below group) 18%, 19%, 20%, or 21% body fat, the above group always showed a significantly higher occurrence of abnormal values for clinical parameters than the below group.
The subjects were further divided into 3 groups: 250 subjects with %fat below 17.9% (N group), 63 subjects with %fat between 18% and 19.9% (MO group), and 144 subjects with %fat above 20% (O group) . The O group showed the highest occurrence of abnormal values for clinical parameters, followed in order by the MO and N groups. These differences were significant. The O group showed a significantly lower mean value of HDL-C and significantly higher mean values of TC, TC/HDL-C, TG, GPT, SBP, DBP and FBS than the N group. The O group also showed significantly higher mean values for WBC and RBC than the MO and N groups. The O and MO groups showed significantly higer mean values of β-L, γ-GTP and UA than the N group.
From these results and the fact that a value above 20% fat is widely used as a criterion for evaluation of obesity, men with a %fat range of 18.0% to 19.9% are defined as mildly obese, whereas those with above 20% fat are defined as obese.
The subjects were further divided into 3 gooups: %fat below (non-obese) or above (obese) 20%, and VO₂max/wt above (fit) or below (unfit) values recommended by the Ministry of Public Welfare for each age group. One hundred fifty-one subjects were non-obese and fit (NF group), 142 subjects were non-obese and unfit (NU group) and 107 subjects were obese and unfit (OU group) . The NF group showed the lowest occurrence of abnormal values for clinical parameters, followed in order by the NU and OU groups. These differences were significant. Thus, it seems appropriate to evaluate obesity by using a combination of %fat and VO₂max/wt.

This is the third symposium on 'cancer and acupuncture and moxibustion'. Many physicians and intellectuals are skeptical of the use of Western medicine for cancer patients, which often lead to serious adverse events. Acupuncture and moxibustion, which is capable of improving quality of life (QOL) and activating immunity with minimal side effects is also expected to have beneficial effects on various stages of cancer patients, such as prevention of development or recurrence of cancer and palliative care. In fact, evidence has recently accumulated in the field. Dr. Fukuda, Associate Professor of Meiji University of Integrative Medicine, who reported the usefulness of acupuncture and moxibustion in palliative care in the first symposium and bibliographical information in the second has reported this time on the topic of safety and effectiveness of acupuncture on chemotherapy-induced peripheral neuropathy. Dr. Kurokawa from the National Defense Medical College reported the effectiveness of acupuncture on physical and psychological symptoms, QOL, prevention of adverse events, and pre-and post-operative disorders in cancer patients. Dr. Kouchi from Saitama Medical School reported on the usefulness of acupuncture in the university hospital and factors which influence the effect. Dr. Nakamura from Morinomiya University presented a case with chemotherapy-related symptoms who had been cared for with a long-term application of moxibustion. In contrast to these reports on the efficacy of the acupuncture for chemotherapy-and radiotherapy-induced side effects, Dr. Magara from Somon Hachipuji Clinic, who had consistently reported a preventive effect of autonomic immune therapy that involves acupuncture without Western clinical treatment from the first symposium, this time presented topics regarding improvement in the immunity by increasing various cytokines, the possibility of reduction of a tumor even in a case of advanced cancer that cannot be treated with a surgical approach, reduction of the recurrence rate among cases who were treated with his approach as compared with those under conventional approaches. He insisted we should concentrate our efforts on research on preventing the recurrence of cancer with approaches that activates the natural healing process of human beings.
We concluded that clinical trials with a larger sample are needed to clearly identify the usefulness of acupuncture and moxibustion for cancer patients.

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 individual feedback intervention (IFB) or general video intervention (GV) on promoting daily physical activity. One hundred and thirty-six community-dwelling people volunteered as subjects and participated in the 2-month walking program provided as a correspondence course. The subjects were randomly allocated to one of four groups, which consisted of either IFB or GV. Each of the groups was based on behavioral science. The stage of change in exercise, self-efficacy for exercise and daily physical activity were measured before and after intervention 4 months later during the follow-up period. There were statistically significant effects of both ‘time’ (F=3.71, p=0.026) and ‘time’בIFB’ (F=3.76, p=0.025) in self-efficacy for exercise; while there was no significant effect of interaction between ‘time’בGV’. As for daily physical activity, there was no significant effect of the interaction both of ‘time’בIFB’ and ‘time’בGV’. These results suggest the IFB of promoting self-efficacy for exercise.

Objective: In The Hospital of Hyogo College of Medicine, a oral rinse containing polaprezinc (PZ), a zinc-containing drug for gastric ulcers, was used as a hospital preparation to treat radiotherapy-related oral mucositis, and its efficacy was reported.  However, the dispersibility of PZ for carboxymethylcellulose sodium (CMC), which was used as the base of the oral rinse, was unfavorable, raising an issue.  In this study, we newly prepared a PZ oral rinse containing carboxyvinyl polymer (CP) as a base, and examined its usefulness.
Methods: A questionnaire survey regarding the usefulness involving 10 healthy volunteers and a pharmaceutical test were conducted.
Results: The results of the questionnaire survey showed that the optimal concentration of CP was 0.5%.  There were no serial changes in the pH, adhesiveness, or PZ content for 7 days after preparation.  Furthermore, there were no differences between CMC and CP.  The dispersibility of PZ in the oral rinse containing CP as a base was more favorable than that in the oral rinse containing CMC.
Conclusion: The results of this study suggest that the PZ oral rinse containing 0.5% CP as a base is useful, and that its stability is similar to that of the oral rinse containing CMC as a base.

Objective: Oral mucositis is one of the serious and frequent acute side effects due to chemoradiotherapy (CRT) for head and neck cancer.  In this study, we prepared an oral rinse as a hospital preparation for the treatment of oral mucositis, which was a suspension of polaprezinc (PZ), a zinc-containing therapeutic agent for gastric ulcer, in carboxyvinyl polymer (CP), a water-soluble large molecule.
Methods: We carried out stability tests of the PZ-CP oral rinse, and investigated its effects on the radiation-induced oral mucositis in patients who received CRT for head and neck cancer.
Results: In the stability test, the pH, viscosity, adhesion and PZ content in the preparations did not change throughout 28 days after preparation.  In the clinical evaluation on the basis of the distribution of the Grade of oral mucositis, the Grade of oral mucositis in the PZ group was significantly lower than in the control group at 6 and 7 weeks (p=0.016, p=0.018).  The incidence of severe oral mucositis of Grade 3 was 15.0% (3 cases) in the PZ group and 41.7% (10 cases) in the control group at 6 weeks, and was 15.0% (3 cases) in the PZ group and 33.3% (8 cases) in the control group at 7 weeks.
Conclusion: These results suggest that PZ-CP oral rinse inhibits the aggravation of oral mucositis induced by CRT or promotes its healing.

Purpose: To consider the relationship between undergraduate tests and the national examinations administered to undergraduate students, predict the outcome of national examinations, and determine the cutoff value for passing national examinations.Methods: We studied students who graduated in March 2016 from five rehabilitation colleges for physiotherapists and occupational therapists. We investigated the national examination results of physical therapists and occupational therapists, undergraduate tests such as admission tests, first year student final exams, second year student final exams, and three tests administered to third year students. Statistical analysis, Pearson's Correlation coefficient, and logistic regression analysis were used. The cutoff value was determined by recipient operation characteristic curve.Results: Each performance test and national examination showed a significant positive correlation with the Department of Physical Therapy (305, pass rate 83.6%), Department of Occupational Therapy (89, pass rate 100%) and the predictive examination for the Department of Physical Therapy. The first and third simulation tests were extracted (p<0.05), each cutoff value was 130.5 points and 169.5 points respective.Conclusion: We established a relationship between undergraduate tests and national examinations. We also clarified the predictive test for the physical therapist national examination and its cutoff value.

We report a case involving a young female patient with severe mandibular retrognathism accompanied by mandibular condylar deformity that was effectively treated with Le Fort I osteotomy and two genioplasty procedures. At 9 years and 9 months of age, she was diagnosed with Angle Class III malocclusion, a skeletal Class II jaw relationship, an anterior crossbite, congenital absence of some teeth, and a left-sided cleft lip and palate. Although the anterior crossbite and narrow maxillary arch were corrected by interceptive orthodontic treatment, severe mandibular hypogrowth resulted in unexpectedly severe mandibular retrognathism after growth completion. Moreover, bilateral condylar deformities were observed, and we suspected progressive condylar resorption (PCR). There was a high risk of further condylar resorption with mandibular advancement surgery; therefore, Le Fort I osteotomy with two genioplasty procedures was performed to achieve counterclockwise rotation of the mandible and avoid ingravescence of the condylar deformities. The total duration of active treatment was 42 months. The maxilla was impacted by 7.0 mm and 5.0 mm in the incisor and molar regions, respectively, while the pogonion was advanced by 18.0 mm. This significantly resolved both skeletal disharmony and malocclusion. Furthermore, the hyoid bone was advanced, the pharyngeal airway space was increased, and the morphology of the mandibular condyle was maintained. At the 30-month follow-up examination, the patient exhibited a satisfactory facial profile. The findings from our case suggest that severe mandibular retrognathism with condylar deformities can be effectively treated without surgical mandibular advancement, thus decreasing the risk of PCR.
