Because of the rapid progress in genetic research, only a small part of what is known about clinical genetics is taught in medical schools. At Nippon Medical School a clinical genetics course for fourth-year students started in October 2002. In the present study, we used a questionnaire to investigate how well second-year medical school students understand clinical genetics. The results of the questionnaire suggested that many students are confused about basic concepts in clinical genetics, such as the differences between inherited disease and diseased caused by genetic disorders and between hereditary and chromosomal disorders and also suggested that education in clinical genetics is needed in medical schools. In the United States, guidelines for teaching genetics in medical schools have been established. However, in Japan, considering the lack of consensus about medical genetics terminology, to disseminate correct knowledge about clinical genetics, the present situation of medical genetics education in medical schools must be clarified, and various other measures, such as establishing what information should be taught, should be carried out.

During past 15 years 78 patients were operated for thoracic aortic aneurysm. Patients operated in emergency or dead within 24 hours after operation or with preoperative renal failure were excluded and remaining 65 patients were studied for factors affecting postoperative renal dysfunction. Postoperative renal dysfunction was based on the serum creatinine value which was within normal limit before operation and exceeded 1.5mg/dl after operation, or which increased by 1mg/dl and more from preoperative value. 23 patiens developed postoperative renal dysfunction and the incidence was 35.4%. As preoperative factors, old age, male and high value of preoperative serum creatinine were significantly (p<0.01) related with postoperative renal dysfunction. As intraoperative factor, decreased urine output per operative hour was significantly (0.01<p<0.05) related. Other preoperative factors; hypertension, diabetes, location of aneurysm, dissecting and nondissecting, intraoperative factors; operation time, volume of operative bleeding, minimum systolic blood pressure during operation, clamping time of aorta, minimum temperature of rectum, difference of adjuncts (temporary shunt or extracorporeal circulation), postoperative factors; systolic blood pressure at arriving ICU, urine output of first postoperative day were not significantly related. Between the operative procedures of graft replacement and extraanatomic bypass, no significant difference was recognized in occurrence of postoperative renal dysfunction, but patients with patch angioplasty etc. developed no renal dysfunction. In the complications within one week after operation, central nervous system dysfunction, infection and hemorrhage had a tendency to occur together with renal dysfunction. For prevention of postoperative renal dysfunction it is important to minimize the renal ischemia, to protect the kidney and to maintain urine output during operation, particularly in patients of preoperative decreased function of kidney and of old male with advanced arteriosclerosis. Also it is necessary to choose the less invasive procedure of operation for patients of severely decreased function of kidney and to consider about organ system relations in patients of postoperative renal dysfunction.

Isolated left-side inferior vena cava is rare, there being only four cases associated with abdominal aortic aneurysm reported so far in the Japanese literature. A 72-year-old man was admitted to our hospital for the evaluation of an abdominal pulsatile mass. CT scan revealed abdominal aortic aneurysm with isolated left-sided inferior vena cava. Aneurysmectomy and bifurcated graft replacement was performed with retracting inferior vena cava. The postoperative course was uneventful.

Objective: Acanthopanax senticosus Harms extract (ASE) is an ingredient of functional foods, such as health supplements, in Japan. We investigated the effects of ASE on CYP2C9 activity.
Methods and Results: CYP2C9-catalyzed diclofenac 4′-hydroxylase activities in human intestinal and liver microsomes (abbreviated as HIM and HLM, respectively) were significantly decreased by the addition of ASE in a concentration-dependent manner. Kinetic studies of diclofenac 4′-hydroxylase in HLM revealed that ASE addition significantly decreased V_max but had no effect on K_m. These results suggest that diclofenac 4′-hydroxylase activity is suppressed by ASE addition in a non-competitive manner. Then, we investigated the time courses of diclofenac 4′-hydroxylase activity in rat liver microsomes after ASE oral administration (50 to 400 mg/kg). Diclofenac 4′-hydroxylase activities were significantly lowered by the administration of 200 and 400 mg/kg ASE at 0.5 to 4 hr compared with control (0 hr). Furthermore, we investigated the effects of ASE oral administration on the pharmacokinetics of tolbutamide (substrate for CYP2C9) in rats. The area under the concentration-time curve of tolbutamide after ASE oral administration (400 mg/kg) was enhanced by approximately 1.6 times compared with that without ASE oral administration.
Conclusion: These findings indicated that ASE inhibits human intestinal and hepatic CYP2C9 activities.

Our present study investigated DNA sequence analysis of Human Papillomavirus (HPV) typc-33 in sexually active women. In present study 22 HPV-33 positive Endocervical specimens were obtained by use of Polymerase Chain Reaction (PCR), from total 500 participants, and further analyzed by DNA sequencing of the Long Control Region (LCR), E6 and E7 genes. For the genes LCR and E6 13 samples, for the gene E7 all 22 HPV-33 positive samples were sequenced by Applied Biosystcms. All 22 HPV-33 positive participants were Mongolian nationality. Most common Non-prototype-Likc variant in LCR is HPV-33 LCR-17 (11/13). one HPV-33 LCR-5 (1/13), and only one Prototype was found (1/13). In the E6, 12 samples were variant 33-E6-6 (12/13), and one prototype was found. lntheE7, 13 Prototype (13/22), 11 Non-prototype-Like variants were found. From the sequence result of gene sites in LCR, E6 and E7 most common HPV-33 variant in Mongolia is MN-17-6-0 (10/13), HPV-33 MN-0-6-0 (1/13), HPV-33 MN-5-6-0 (1/13) and one Montreal variant were found HPV-33 MT-17-0-0 (1/13). We identified 3 new variants of 11PV-33 which we called MN (Mongolia). From sequence result in 3 sites of genes, LCR is more variable compare with E6 and E7. F.6 were variable compare with E7.

Great interest has been paid to moxibustion from many thousand years ago as one of effective folk medicine, hewever while through the years only practical use has been emphasized, its scientific basis has remained unclear. About 60 years ago Dr. Shimetaro Hara studied on moxibustion histologically and pharmacologically and suspected the widespread meridian theory (theory of Keiraku) in explaination of the moxibustion effect and presented “non-specific heat aggregated autologous tissue protein therapy” theory. It can be said that his theory coincides with today's nonspecific immune regulatory therapy applied to cancer and immune deficient diseases.
Using 9 Week-old femal SLC-Wistar rats, we administered regular moxa moxibustion or electrical moxibustion under the same circumstances as regular moxa moxibustion daily fom definite duration. Following moxibustion, using 0.5mg of HG as an antigen together with Freund's incomplete adjuvant, we sensitized two sites on the foot pads of rats once or twice (2 weeks later).
On the 7th day after the primary or secondary sensitization 1.0mg of HγG in 0.1ml of saline was injected subcutaneously at an intact sites of foot pad and foot pad edema formed was measured periodically. Taking sheep red blood cells and using refined human IgG myeloma protein as an antigen and glutar-aldehyde an a fixing reagent, we admindstered PHA (passive hamagglutination) for the assay of serum antibody level of moxibusted animals.
In comparison with moxibustion, on the same schedule 5mg/kg of levamisole (LEV) was adminstered orally daily and results were examined.
The inflammatory edematous reaction which was induced with the HγG reached a peak 3 hour salter the antigen challenged on the intact foot pad, then gradually weakened until it returned to normal was an immediate type skin reaction.
This edema rection in the moxibustion group and the LEV group also when compared with the control group was significantly stregthened. The antibody titer according to the PHA reaction showed after the primary sensitization, no remarkable increase in the moxibustion group, in fact, the level was about the same as the control. After the secondary sensitization the antibody titer of the moxibustion group was much higher than that of the LEV group compared with the control.
And the strongest effects were obtained in the moxibustion and LEV group. As an immune activator, the functional mechanism of moxibustion compared with levamisole which is said to have some function on the T cells will become clear in the future.
Moreover, it will be clinically possible to use moxibustion as a supplementary therapy to build up the immune response.

This study examined if modified Wingate Anaerobic Test (Wingate method) and Evans-Quinney Anaerobic Test (Evan-Quinney method) procedures could be applied to the meas-urement of maximal anaerobic power output (POmax) which is usually determined during 8-s maximal cycling depending predominantly on alactacid energy sources. The criterion measure of POmax was either the highest power output among 5 to 7 power outputs meas-ured at different workloads (Selection method) or the peak power output estimated from quadratic regression (Peak method) . POmax and anaerobic power outputs with these four methods were measured during 8-s maximal cycling on Monark bicycle ergometer with toe-stirrups. Forty-four young athletes (25 males and 19 females) served as subjects. Analysis of the data indicated that: 1) There was a very high correlation (r=0.995, P<0.001) between POmax determined by Selection and Peak methods, with no statistical difference in their absolute means. 2) POmax determined by Wingate method correlated (r=0.937, P<0.001) significantly with POmax determined by Peak method, while mean values differed signif-icantly. 3) POmax determined by Evans-Quinney method also correlated (r=0.890, P<0001) significantly with that determined by Peak method; however, mean values differed significantly and degree of the difference in POmax was particularly greater in females. It is concluded that both Wingate and Evans-Quinney methods with a cycling duration of 8 s might be applicable for the assessment of POmax by utilizing linear regression equations developed in this study. Further studies are needed as to the feasibility of using these methods, particularly on females.

The purpose of this study was to measure the effectiveness of RPE on exercise intensity for senior citizens. A maximum workload test was administered with the use of a bicycle ergometer on older male and female subjects. The results of our study can be summarized as follows:
1. Two trials were performed on separate days. A high correlation coefficient for the first trial and the second trial was found. The reliability for the male group was r=0.76 (p<0.01) and that for the female group r=0.90 (p<0.01) .
2. A correlation range of r=0.55-0.79 (p (0.01) was found for RPE and physiological exercise intensity (which includes oxygen intake and heart rate) . A higher result was found when the relative value was used in the analysis of the oxygen intake and the heart rate instead of the absolute value.
3. Significant correlation coefficients of r=0.63-0.64 (p<0.01) were found for RPE and the work load in terms of watt units.
4. The majority of the physiological variables were statistically determined ; however, there were no correlations between RPE and systolic blood pressure.
In conclusion, based on our study, we have found that RPE and HR ; RPE and %Vo₂max: RPE and watts grouped individually had a high correlation for effectiveness. The only exception in our study was the RPE and the blood pressure group because no correlation was found overall. Therefore, the overall effectiveness of RPE was proven to be quite sensitive even for senior citizens, and as a result RPE can be utilized when exercise is prescribed for evaluatory measurement in senior citizens.
