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.

Unkei-to was used successfully to treat three patients with primary Sjögren's syndrome (pSjS). The first case was a 67-year-old woman. In April 1993, she visited Tonami General Hospital with the symptom of dry eyes. Her condition was diagnosed as pSjS from being antinuclear antibody (ANA) positive, dry eye, and decrease of saliva secretion. She used eye drops, but her dry eye did not improve, she visited our department in June 1995. Administration of Unkei-to improved her symptoms after 6 months of treatment.
The second case was a 73-year-old woman. In 1987, she was treated in our hospital for lumbago based on spondylosis. In 1991, she began to suffer from pain and swelling of the right sterno-clavicular joint (RSCJ) and was admitted. She was anti-SS-A/Ro ANA positive, schirmer's test was positive, lymphocyte infiltration was observed by lip biopsy, and thus pSjS was diagnosed. Treatment with Unkei-to resulted in the improvement of pain and swelling of RSCJ, as well as a decrease in serum C-reactive protein. But a favorable effect on dry mouth was not attained in this case.
The third case involved a 39-year-old woman who began to experience polyarthralgia and dry mouth in June 1991. She visited a neighborhood hospital and was diagnosed as pSjS from hyper γ-globulinemia, anti SS-A ANA positivity, and decrease of saliva secretion. She first visited our hospital in March 1994. We administered Keishikaryojutubu-to and improvement of polyarthralgia was observed. Subsequently, she suffered from symptoms of dry eye and dry mouth. We treated her with Unkei-to, which improved the symptoms of dryness, but not polyarthralgia in this case.
These observations suggest that Unkei-to might be a useful agent for the treatment of pSjS.

To clarify a mechanism of psychologic relaxation by artificial hot spring, the effect of hot spring bathing on psychologic sweating was studied in 11 healthy subjects (1 female and 10 males, age 26±5.7 years). After lying in the supine position for 5 minutes, the subjects were asked to take a bath with plain water or artificial hot spring for 5 minutes in the sitting position. The temperature of the bath was 40°C. To prepare the artificial hot spring, sodium sulfate tablet (Tsumura & Co.) was solved in 200L of plain water. For the measurement of psychologic sweating, Perspiro (Suzuken, Co. Ltd) was used. Sensor was attached to the first finger by biphasic adhesive tape. The psychologic sweating was induced by deep respiration, mental arithmetic, hand grip, blood pressure measurement and blood sampling. There were no statistical significant differences of CV value, heart rate, blood pressures, catecholamine values and serum β endorphin levels before and after the bathing. The psychologic sweating markedly decreased after the bathing (11.5±19.6 to 1.1±2.7 for plain water bathing, 14.9±21.9 to 1.6±5.1 for artificial hot spring, N. S.).
The decrease in psychologic sweating after bathing suggests the action of psychologic relaxation by bathing.

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.

In the previous papers, we reported the effects of electronic moxibustion on immune response of experimental rats to the exogeneous antigens, human γ-globulin.
The results supported the theory, “non-specific heat aggregeted autologous tissue protein stimulation therapy” presented by Dr. Shimetaro Hara in 1933.
Therefore, in this paper we chose two kinds of antigens, one is the T-cell dependent antigen, dinitrophenylated keyhole limpet hemocyanin (DNP-KLH), the other is the T-cell independent antigen dinitrophenylated Ficoll (DNP-Ficoll) to analyse the mechanism of electronic moxibustion whether it enhances the immune response or not.
Using 9 weeks old femal SLC-Wistar rats, we administered the electronic moxibustion according to the method reported in the previous papers. Following daily moxibustion for 8 weeks, antigens were giver twice at intervals of one week together with Freund's complete adjuvant. And 4 days later from the last antigen stimulation direct, DNP plaque forming cells in the spleen were counted.
The results obviously showed daily electronic moxibustion for 8 weeks enhanced immune response against the T-cell dependent antigen (DNP-KLH) stimulated rats but no effect on the immune response to the T-cell independent antigen (DNP-Ficoll) stimulated rats.
The daily electronic moxibustion for 4 weeks to rats failed to show any effective results against both antigens stimulation.
The responses of spleen cells against mitogenic lectins, PHA, Con A and PWM were analysed 3 days after the incubation with lectins by tritiated thymidine up takes into cells. The results also showed the animal group received the electronic moxibustion for 8 weeks manifested higher response against the one of T-cell mitogens, Con A compared with either the group received the electronic moxibustion for 4 weeks or the control group, not received any treatment.
These results suggested that the immune activation mechanism exhibited by the electronic moxibustion is via the activation of T-cell function and the electronic moxibustion does not act on B cell nor antibody forming cells.
The direct effects on the animal skin by the electronic moxibustion were shown exactly the same physical characteristics as the conventional moxibustion method as reported in the previous papers. Therefore, we could expect the similar T-cell activation effect on the immune response by the conventional moxibustion.
But from our results to get such a T-cell activation by the electronic moxibustion, it has been necessary to administrate the electronic moxibustion daily at least for more than 4 weeks.
Next we would like to make clear what kinds of subpopulation in the T-cell populations are activated by the electronic moxibustion.
Before the clinical administration of the electronic moxibustion as one of immune activators, it is necessary to investigate further about the optimal amounts of the moxibustion, effects of the moxibustion on the cellular immunity or tumor immunity.
